consumptive landscapes + annotated plan/ section
Consuming Topography
Loverina Cruz (KUL) Md Rafiqul Islam (KUL) Winnie Amondi Sawo (TUK) Victor Omondi Ongor (TUK)
Ndenderu’s landscape is choreographed by steep valley slopes and river systems that structure agricultural activities. The interplay of the water and topography is crucial for the agricultural production of Ndenderu, influencing landscape appropriations and consumption patterns. How are natural landscape systems influencing consumptive landscape appropriations?
36

Where is the balance?
Hagar Faggal (KUL) Mohammed Leruk (TUK) Matimba Ngobeni (WITS) Natalia Recalde (KUL)
Rapid Urbanization has engulfed Ndenderu area, threatening indigenous landscape appropriations and practices. Increasing densification is probably the biggest casualty of the rapid landscape transformations. How are current modes of human consumption of nature shaping (in) balanced landscapes?
37
consumptive landscapes + process diagram
(Re)working the land
Sharmin Kabir Shimul (KUL) Bob Nyachiro (TUK) Victor Kiprop (TUK) Silvia Parra (KUL)
Ndenderu’s natural landscape has catered for a rich diversity of agricultural uses. How are different inhabitants working these lands, appropriating and re-creating the valleys and slopes?
38
productive landscapes + annotated plan/ section
A farmer’s productive land
Daniela GarcĂa-Rojas (KUL) Gaarith Williams (KUL) Daniel Matata (TUK) Victor Obinge (TUK)
While rapid urbanization in Ndenderu has critically reduced rural activities, individual agricultural and economic actions can positively impact local and territorial contexts, while even interacting with the global market. How does a particular plot of land in Banana Hill embody multilayered productive landscapes and macro-networks?
39
productive landscapes + collage
Western Bypass market relations
Fahri Abdala-Reyes (KUL) Karmen Hoge (KUL) Paul Mumbo Musili (TUK)
The Western Bypass construction comes with heavy land speculation, while providing new opportunities for connecting and integrating Ndenderu to the city of Nairobi. The new linkage also allows to connect roadside markets with the entire market network of Nairobi. What kind of market network could the Western Bypass through the Ndenderu-Wangige valley system establish?
40

Water prints
Elizabeth Agwa (TUK) Darina Andreeva (KUL) Rachid Garcia Elmosri (KUL) Felix Wambua (TUK)
Ndenderu is a peculiar territory of dispersed river valleys,directly correlating to anthropogenic cycles of use and appropriation. While wider valleys seem to host more centralized supply systems of reticulation pipes and springs, narrow ones rely more on decentralized boreholes and open waterways. How do these diverse water systems intertwine and interact?
41
typology + annotated plan/ section
Spatial disparity across valley system
Grace Kamweru (KUL) Luis Villadiego (KUL) Jepchumba Lagat (TUK) Victor Kipkoech (TUK)
Land use in Ndenderu and its surroundings is defined by its topographical and administrative characteristics, where clear border divisions can be seen due to these phenomena. How do the topography and planning regulations influence the typology of housing, infrastructure, and land use?
42

Transitions of appropriation
Emma Brecher (WITS) Zeeshan Ghani (KUL) Santiago Cortinez (KUL) Beatrice Mwangi (TUK)
Different patterns of landscape appropriation are affecting the thresholds between individual properties and the common territory. Regarding the linear settlement structures of the area, how do diverse thresholds impact socio-economic associations in the urbanizing valleys of Ndenderu?
43

Water equity?
Benjamin Baggott (KUL) Khanh Nguyen (KUL) Ernest Ndungu (TUK)
The privatisation of water supply through boreholes has given the majority of the population access to a reliable water source. However, has monopolisation and privatisation of water opened up new avenues for both environmental and social abuse?

Kikuyu is a town expanding at the confluence of newly constructed highway and railway infrastructures, fragmenting it into an urban archipelago. Occupation was dominated by sedentary agricultural communities and it is home to Ondiri Swamp, a highly exploited underground watersource for Nairobi and neighboring counties, that some call an underground water tower.

Benjamin Baggott (KUL) Khanh Nguyen (KUL) Ernest Ndungu (TUK)
The Ondiri Wetland is known to many as an “underground water tank� making it an important water source to dependents such as adjacent industries, Kikuyu Springs and Nairobi City. How can new strategies be implemented in and arround the Ondiri Wetland to counter its current perception and use as a dumping ground and free water source, to one that is preserved, recognised and celebrated for its ecological importance?

Forest Consumption
Grace Kamweru (KUL) Luis Villadiego (KUL) Jepchumba Lagat (TUK) Victor Kipkoech (TUK)
Urban development in Kikuyu sub-county is gradually threatening the limited forest resources in the area. Housing, new roads, railways expansion and other infrastructural development has led to a significant decrease of forest resources in the urban areas. New settlements and use of charcoal fuel in the rural areas also exacerbate this threat. How do we create a balance between human development activities and existing biodiversity?
51

Dead Ends
Elizabeth Agwa (TUK) Darina Andreeva (KUL) Rachid Garcia Elmosri (KUL) Felix Wambua (TUK)
The urbanized valley of Ongata Rongai, home to the Mbagathi river, is replete of dead ends, abrupt enclosures, fences and barriers. How has this patchwork of dead ends emerged over time? And what challenges does it pose for future urban development and design?
52
consumptive landscapes + process diagram
Water communities
Emma Brecher (WITS) Zeeshan Ghani (KUL) Santiago Cortinez (KUL) Beatrice Mwangi (TUK)
The water consumption patterns through natural source pumping, boreholes and municipal pipelines affect community relationships and value associations in the water catchment and distribution areas. As the town environs continue to grow and their need for water increases, how can these consumption patterns be spatially manipulated to enhance social relationships?
53
productive landscapes + annotated plan/ section
Ecology or economy?
Sharmin Kabir Shimul (KUL) Bob Nyachiro (TUK) Victor Kiprop (TUK) Silvia Parra (KUL)
The green house business of Kikuyu, both subsistence and industrial, has exponentially grown over the last years due to decreasing land sizes and reduced returns on open farmlands, causing environmental deterioration of natural water resources. What strategies need to be developed to create more environmentally friendly farming techniques across the Kikuyu landscape?
54
productive landscapes + collage
Industrial Ecosystem
Loverina Cruz (KUL) Md Rafiqul Islam (KUL) Winnie Amondi Sawo (TUK) Victor Omondi Ongor (TUK)
Growing industry in and around Kikuyu is putting profound pressure on natural reservoirs, water towers and landscapes of the area. How do these industries produce a new urban landscape, attracting new towns, developing centralities, and establishing economic circularity? How could industrial production be designed and controlled to restore and maintain the area’s ecological integrity?
55

Valley resistance
Hagar Faggal (KUL) Mohammed Leruk (TUK) Matimba Ngobeni (WITS) Natalia Recalde (KUL)
The valley around Kikuyu town comprises of a rich series of wetlands and forests creating unique conditions for a variety of (potentially exploitative) economic activities including subsistence agriculture, large scale industries and high density housing. What strategies need to be considered to protect the natural logics of the valley system in the face of increasing production cycles?

Mobility typologies
Daniela GarcĂa-Rojas (KUL) Gaarith Williams (KUL) Daniel Matata (TUK) Victor Obinge (TUK)
The rapid urbanization of Kikuyu area has been framed by the construction of new mobility networks that heavily contrast with previous rural and peri-urban roads. Which new building typologies have and can emerge along Kikuyu’s rapidly densifying infrastructural systems?
57
typology + process diagram
Mutating typologies
Fahri Abdala-Reyes (KUL) Karmen Hoge (KUL) Paul Mumbo Musili (TUK)
As the Kikuyu landscape continues to be subdivided by large infrastructural projects, it has shaped an archipelago of mutating urban morphologies and housing typologies, each closely bound up with its distinct placement in the landscape. How can new flexible forms of urbanization be designed to accommodate this continuously changing urban landscape?

Ongata Rongai, sits in the lowlands of Ngong Hills that form a transition to the Athi-Kapiti plains which were formerly recognized as the Kitengela conservancy area. Now an emerging vibrant town, Ongata Rongai, adjacent to the Nairobi National Park and previously home to the pastoral Maasai tribe, is confronted by dilemmas of urbanization. The predominant pastoral communities still own most of the land, but new sedentary forms of urbanization pose a stark contrast to their indigenous practices. This is more evident by rising human-wildlife conflicts that expose the neglect of harmonious coexistence of both man and wildlife.

The economy of the city of Ongata Rongai depends largely on the meat market and the construction industry. Nevertheless, urban development is gradually replacing pasturelands, which results in the permanence of informal livestock pens within the city and reduced grasslands. In what way can space be redistributed to reorganize informality in the construction and the meat industries of Ongata Rongai?

01_Rethinking the heritage landscape. NATIONAL ROYAL PARK
The first case concerns the idea of natural heritage in metropolitan context. The National Royal Park (hereinafter, NUP) is an example of historical conservation, legal protection, and collaborative relation with urban areas. NUP is a proto case of an ecological urban park of “2 700 hectares characterized by both - leaved and mixed forests and an open grass-dominated landscape” (Elmqvist et al. 2004, 312), which is known for its reserve of oaks that, until today, are supplying timber for the royal navy (Erixon et al. 2018).

Heritage landscape management: the historic narrative regarding the park is an important frame for preservation. National policies since the 14th century have been enacted to prohibit, to expropriate and to protect the natural reserve (Elmqvist et al. 2004), all of them related to oak exploitation for ship building (Erixon et al. 2018) (Elmqvist et al. 2004). NUP represents a unique case of productive and heritage landscape management over time. Moreover, as Uggla states, the park represents ancient and contemporaneous ideals (2014).

Furthermore, regarding ecological coexistence on the park, the preservation of oak trees is closely linked with the existing wildlife, in particular the interaction jay-oak where the birds (jay) play the role of a gardener (Erixon et al. 2018). As a consequence, Erixon at al. and Elmqvist et al. point out that the preservation of birds depends of the promotion of well-connected large patches of conifers, understanding that the latest are the natural environment for nesting (2018) (2004). “The lack of other effective inter-patch acorn dispersers makes the oak dominated landscape fragile” (Elmqvist et al. 2004, 722).
The created narrative regarding the history is an important frame to preserve this park, which works as a natural structure in the city (Uggla 2014). “The area’s history, with its transformation from agricultural landscape to royal hunting ground, has contributed to the park’s specific landscape, which combines open land and forest” (Uggla 2014, 373).

Contrary to what one might think, productivity can save the landscape. It is broadly recognised that the given relationship along a stream can generate different interactions. “Water equals power. The capture, storage and distribution of water inextricably bind physical and social processes into a thorny relationship between nature and society” (Shannon 2007, 6). The good management of water in a large-scale could promote peace and diplomatic relation among States. Moreover, in a small-scale the relation among communities, which usufruct from the same stream – are also replicated, in a smaller scale, as the same relationship among communities.

The third case is an example of coexistence among the forests, the rivers and the ocean. “A fisherman of the Kesennuma Bay introduced the famous phrase, ‘The forest is a lover of the sea’” (Yanagi 2019, 33). Shigeatsu Hatakeyama – an oyster farm of Kasennuma Bay- who points out that the lack of iron on the sea reduces the quantity of plankton on the bay, which is its main aliment (Yanagi 2019). According to the fisherman, the research made by Katsuhiko Matsunaga supported the planting trees movement upstream of rivers that he has promoted (UN News 2017). “Freshwater from the terrestrial area has a strong influence on the Fe [iron] concentrations in surface seawater in the coastal areas, especially close to the river mouths.” (Yamamoto, et al. 2020, 12).

“Many trees must be cut down to build new houses [after the earthquake of 2011](…) I think this is a great opportunity to care for the forests by rebuilding houses with local trees [cedars planted since WWII], light will reach into the forests, revitalizing the forest, rivers, and finally, the ocean as well” (Hatakeyama 2011).

The second case is about defining the territory in relation to the coexistence between land and the wildlife migration. The cases can act as a theorical framework to redefine both the concept of territory and landscape-scale intervention when the wildlife is taken into account as part of the productive process. Migrations flows take large portion of land, which natural boundaries are more related to natural elements than to administrative boundaries. Wellknown are the migratory routes of species all over the world and conservation efforts to preserve them.

The Gateway National Recreational Area (hereinafter, GNRA) is an example of coexistence between a national park and a dense coastal urban population, facing threats to a greater extend from outside of its boundaries, such as pollution or presence of non-native species (Mahan et al. 2009). “GNRA is a complex mosaic of natural and cultural resources and recreational facilities interwoven with New York City neighbourhoods and small New Jersey towns” (Mahan 2015, 51). Thus, “The Jamaica Bay Wildlife Refuge (…) provides excellent nesting, migrating, and wintering habitats for over 300 species of shore-, land, and water birds” (Brown et al. 2001, 208).

The national park promotes a short-distance migration network of birds on the estuarine shoreline. “A finely fragmented habitat is normally perceived as continuous habitat by a wide-ranging species, whereas a coarsely fragmented habitat is discontinuous to all species” (Dramstad et al. 1996, 45). As a consequence, the wildlife refuge of Jamaica Bay depends on the preservation of the rest of the pieces of the mosaic, which, at the same time, are remnants of an ancient landscape no longer found in this populated area.
no longer belong to administrative boundaries. Following the same logic, we should agree that the urban landscape ecology should consider larger scale of migratory flows. As an example, Jamaica Bay depends on Gateway but also, on the several wildlife refuges along the East-Cost.
In this case, the territory is defined by routes, flows and nesting places which
37
Conclusions Why design putting emphasis on nature should be the correct answer? Urban actions based on ecological network obliges to think large scale actions taking into account, for instance, animal migration: “The concrete space constituted by such networks and frontiers had more in common with a spider’s web than with geometrical space” (Lefebvre 1993, 193). The movement and flows of animals, plants, water, wind, and energy make functional the spatial pattern (Dramstad et al. 1996).
New form of linkage Another example is the city of St. Louis (in the USA) which has encouraged the creation of a huge mosaic of gardens in the city; most of them, in private yards, promoting pollination and refuge for the monarch butterflies, which migrate along the route through North America. “They need places to rest and milkweed plants for females to lay their eggs on” (Beatley 2017, 40). The efforts to create a mosaic by 300 gardens in the city demonstrate collective effort and an honest coexistence between human and wildlife. In this case, it is the city, on the way between agricultural fields and the National Park (Mark Twain), which decided to promote becoming a linkage instead of becoming an interference. Therefore, the case of St. Louis responds to one of the features described by Dramstad et al.: “the contribution to the overall system” (1996, 24). Does coexistence mean that there is a spatial competition? It does, however, the creation of new spaces, different to the existing one, attempt to build a collaborative coexistence. For instance, the case of NUP (National Royal Park in Stockholm) aims to preserve a heritage landscape, giving new uses to this gigantic oak reserve. Moreover, its borders and the city’s borders become blur, given rise to an urban park, which, contrary to other examples in the global north, is a unique case of a gigantic patch preserved over the centuries. NUP guides the narrative of Stockholm until today, following the tacit agreement among the citizens who have decided to reinvent its historical
38

As a consequence, the boundaries of a landscape changed and, at this moment, it is time, as a planner, to have different views over the territory: to look again at the nature and its features. Natural reserves such as GNRA, located in a highly densely populated area, is an example of remaining patches which are interconnected by its fauna. In this case, each part depends on the another, becoming all together a wintering habitat for migratory species.
landscape. It is also a successful case of coexistence between citizens and their heritage; understanding that to preserve the patrimony means to preserve the old rather than to accept the new. It means to unveil natural elements that could improve the life of those who have decided to preserve this large green patch in the city. Thus, reinforce the coexistence based on collaboration instead of competition. Can collaborative coexistence define a new scale of urban projects? Actions based on urban ecology invite to rethink the size of the interventions of urban projects. How to define the scale of interventions related to productivity? The answer given by the Fisherman Forest case is that the landscape structure can define boundaries where to intervene. It invites to look around at where the productive areas are and to seek the different elements that affect the productivity. For instance, in the Kasennuma Bay, it is not only fishermen taking care of forests, rather, the vision includes, for instance, all the communities along the stream: woodcutters, rice farmers, small settlements on both the hill and the bay. This case is rich in types of coexistence, between food and environment,
20
At the same time, the case of GNRA emerges as the last chance for the wildlife in an overpopulated territory of New York. Patches related to each other by the wildlife integration is what the preservation of these pieces of lands in the bay makes strong. This could draw a lesson for areas already overpopulated in Nairobi. For instance, today, as MĂŠdard states, natural elements serve as borders in some cases separating poor from other urbanizations (2010). Pieces of forests are seen as a static barrier that divide rather than connect. The case of GNRA shows how separate natural elements in the territory can be joined by invisibles strings. Probably, for the West-Nairobi, the case of St. Louis is more useful as this project promoted the social integration in this segregated racial city. The gardens were spread out in different areas of the city without any distinction. The collective effort became real when different types of communities had the same interest. In this case, the coexistence between human and wildlife, built through new spaces in the city, besides of promoting pollination, have created something new, more related to a multiple collaboration than a competition for the same space.
timber production and fishermen activities, communities; joined by the stream and its tributaries; reinforcing the idea that improving the productivity should include a vision further the regular borders. A new Coexistence in West-Nairobi The west side of Nairobi should be re-founded respecting the visible and invisible natural linkages of the territory. Through the examples of a collaborative actions along the landscape structure, such as the Fisherman Forest or the NUP, West-Nairobi could improve the strengths of its rich natural territory, making stronger the diversities of coexistences present there. By lessons learnt from the studied cases, it is relevant to come up with innovative spaces of coexistence and with bigger scale of intervention. The more people involved, more durable solutions for facing climate change. Doubtless, water, related to a conservation and promotion of a productive landscapes, is the agglutinating element of this territory. West-Nairobi should be re-founded based on the sacredness of its streams, valorizing the events along them and preserving the sacred goods that the streams bring.

Historically, Istanbul has a 1600-year-old practice of urban agriculture. However, due to continuous grow of the city population, settlements spread out to the historically non-urbanized fabrics, in the past – urban agriculture fields. Also, policy of the city did not take in account benefits of food supply provided by these vegetation fragments in the city in the last century, most of them already disappeared.

Long procedure of Yedikule Urban Gardens protection and renovation convey to the citizens reinvention of lost historical fabrics together with functional model of city development. (Elifnaz Durusoy; Duygu Cihanger 2016) Besides, accordingly to the theory of Urban countryside by Quayle Moura, these vegetation islands in dense cities could decrease environmental effects. Generally, cities patterns consist of interwoven historical traces of the past, decisions of the present and transforming models of the future. Hence, in

projecting the future, the analysis of the past could bring methods and ideas of an indigenous urban planning for supporting sustainable model of city efficiency. Thus, regards to Nairobi Urban part, it could be noticed that indigenous techniques of agriculture in Ndenderu and Kikuyu, pastoralism in Ongata Rongai were pushed out from the city centers. Example of Istanbul urban gardens demonstrates that indigenous elements should belong to a modern city as a vital source of coexistence of human-made system and nature. Hence, small elements of previous land use traditions could make a difference for the more resourceful city development.

Continuous Productive Urban Landscapes (CPULs) is a theory, implemented by Katrin Bohn and Andre Viljoen, that describes connection of productive land in urban tissue by creating infrastructure of open urban spaces and network of connected agricultural spots, which can support building environment around. (André Viljoen; Katrin Bohn; Joe Howe 2005) Project of Urban farming completely transformed earlier industrial town.

(“Carrot City - Middlesbrough Urban Farming Project”) Therefore, three main advantages could be highlighted for methodology of CPULs are: protection of bio-diversity, saving the amount of resources used to produce food and waste cycling management. (Bohn and Viljoen) Also, the scale of a Town is in between City and Rural scales, hence, both theories of Urban countries and Rural metropolis could be found in the project, for instance,

integration of urban agriculture and support of communities. In case of Kenia, requirements for more efficient food supply are very complex. Especially, when urbanization pattern eats up productive landscapes that provided food on the past. In the scale of a town, opportunity to preserve and use not occupied by urbanization spots are higher the in the city centers. Thus, empty spots could be connected into productive agricultural landscape in Ndenderu and Kikuyu regions and regards Ongata Rongai region, indigenous occupation of animal husbandry could be reinvented to original land.

Mexico City was founded by Aztecs in the territory of lakes and famous for its irrigation agricultural system of canals – chinampas. However, colonizers drain the lakes towards the Gulf of Mexico. (Vitz 2018) Also, during the centuries city was growing and changed the size from 300,000 inhabitants in Aztecs time to 22,000,000 currently. (Felipe Correa; Carlos Garciavelez Alfaro 2015) Thus, indigenous occupation, one of the most bio-diverse ecological systems in the world is endangered. Nowadays, Mexico City, suffering from the flooding, is the city under water table, and only small expanse of water could be found on the previous place of

the lakes. However, last centuries active debates about value of the lakes and indigenous chinampas systems were evoked. Today, this is the area of protection of indigenous chinampas practices and renovation of the lake system. (Vitz 2018) For instance, project of “The Xochimilco Ecological Park” designed by Mario Schjetnan. On the one side, the project includes renovation of water body along with flora and fauna of the place. On the other side, indigenous ancient methods of food production were preserved. (MXCity 2016) In rural scale, ecological and human-made systems interacted and interwoven the most, with privileges of nature. Consequently, the value of natural resources

is especially vital for these areas. Preserving and high responsibility for the land use management in these areas are crucial for the environment. Situation with chinampas in Mexico City display the real value and possible damages that could happen if artificial systems interrupt natural process. This example is one of the most demonstrative for the whole area of western part of Nairobi. Since this region still has the most valuable resources of water system, forestry, biodiversity, and productive indigenous landscape that work together as one system. Destroying this system elements means that survival of the communities in these territories is in danger. However, as it was identified by
Quayle Moura, people living in Rural metropolis should be supported and be able to survive on the goods received from a land. Hence, proper policy is required to make a difference for that cases. (Quayle 1997)

In a context of water scarcity in a place like West Nairobi, one might ask why water is becoming harder and harder to come by, especially clean water sources. Certainly, there is a global governance crisis regarding water access, but in terms of water equity, not water scarcity (Wilder and Ingram 2018). Nevertheless, access to clean water resources has been

However, underground water extraction may not applicable everywhere due to terrain morphology, source depletion or pollution. In these cases, and considering the rainfall regime, rainwater harvesting becomes a feasible solution. As the nonprofit organisation, PITCHAfrica states, “In Kenya there is seven times the amount of rain falling than is needed by the population” (Walker 2015). With this in mind, the group PITCHAfrica designed and constructed two rural schools in Kenya with rain harvesting facilities.
54
The choice of appointing schools as water harvest centres is not arbitrary: in rural communities, schools are usually places where the community gathers. To incorporate the water component creates a new meaning for these places, involving and educating the community in the water catchment process. These two schools (Usaso Nyro School and Enanda Highschool) were built in 2013 by PITCHAfrica and consist of several buildings that collect rainwater with their roofs. The water is later drained to water tanks and filtered with special filtering pots made by the community.

It is important to acknowledge that, given the project’s scale, a limited amount of people can be served. For this reason, is better applicable –but not limited to- rural environments. However, the Uaso Nyiro School collects annually around 350,000 litres of clean water (Turnbull n.d.), which can sustain close to 3,500 people if we consider a base minimum of a 100 litre per day (United Nations 2014).
Only major urban areas within West Nairobi are provisioned with clean piped water. In the case of Kikuyu, only 63.6% of the population is being supplied by the Kikuyu Water Company (Kilonzo, et al. 2019), extracting water from the Kikuyu Springs. In more rural areas, where water is more difficult to come by, a community-centred solution with a rainwater catchment system might be a feasible solution.

As already mentioned, the depletion of underground sources is one of the main issues due to borehole overuse, along with the increasing soil pollution. In this regard, to be ethical about this method of consumption is to consider the replenishment of underground water sources sustainably. In Kenya, with the lack of green public spaces in urban areas, the absorption of runoff rainwater is both a social and an environmental problem.
56
The Tanner Springs Park in Portland, designed by Atelier Dreiseitl in 2010, collects rainwater runoff from the asphalted streets, storages it in a pond where it is filtered by reeds, and then is absorbed by the soil, recharging the underground sources with clean water. By opening this absorption process to the public, Tanner Springs becomes an education project in itself.

Casablanca, Moroco
Reichen & Robert & Associés, Agence Ter
Considering the fairly dry climate of Casablanca, Morocco, the Anfa Quartier landscape project by Agence Ter, is thought as a water management urban park, sensitive to the rainfall regime. This urban project is centred around a central park designed to be an ‘ecosystem network’ for the entire area through the use of hydrophilic plants, fresh gardens and wooded strips (Agence Ter n.d.).
58
In its essence, the Anfa Quartier is a mix-programmed project structured around a water management park in a former airstrip, that not only reclaims nature within the urban environment but incorporates water, bringing life to the surface ecological systems. One might argue that the water management system presented in the project may not be enough, however, the idea of bringing life to the urban form through water systems remains relevant.
Š Agence Ter
In contrast with the highlands of West Nairobi, the area around Ongata Rongai has a savanna-like climate, where animal herding is still being practised. A project sensitive to the ecological systems through the use of water could be tremendously beneficial to the animals grazing and migrating, added to the benefit of incorporating much needed green areas within the city.
59
Conclusions
From the three approaches to the water question, I argue that water equity, due to the current climate crisis already presented, should incorporate a broader ecological scope; addressing water security for present and future communities imply to rethink the way water is consumed, as we are embedded in a larger ecological system. The strategies of the presented projects aim to solve different issues regarding water ethics: human consumption in isolated areas (Waterbank Schools), replenishment of underground sources (Tanner Springs Park) and revitalization of surface ecology (Anfa Quartier Vert). Taken in consideration West Nairobi’s complex natural and built environment, added to the ever-pressing water situation that affects Sub-Saharan Africa, the three scales of the projects studied become a flexible solution to different situations, tackling issues that go beyond water equity: community building, public space and sustainable urban development. There is an opportunity to go beyond the water equity-human approach by restoring natural water sources and ensuring good water quality for life to thrive; taking a step further to build urban-natural structures for both humans and non-humans. Water ethics can become a better way of planning and designing territories through a water-based strategy in contexts where this resource is endangered.

(Fazenda da Toca 2019)The negative effects of erosion are particularly felt in hills and valleys, which is of concern to the undulating landscape of West Nairobi.
Despite this outward expansion, valuable portions of Nairobi’s agricultural and ecological history are still intact. By encouraging the city, landowners and residents to adopt different techniques that actively promote the preservation of it’s valuable ecological and agricultural landscape, Nairobi will be in a stronger position to confront the multiple challenges brough about by climate change and a growing urban population. Agroforestry is a land use principle that that can go a long way in helping the city of Nairobi conserve it’s agricultural and natural landscapes. Agroforestry is the integration of trees and other perennial shrubs into agricultural systems. (Agroforestry Research Trust 2018)Simply put, it is the combination of forestry and agriculture. Standard agricultural practices are usually concerned with maximising short term yields. While agroforestry tries to emulate natural systems through the combination of trees and farmland. By mimicking natural ecological

Trees on farmlands have multiple benefits for both crops and animals. As the roots of trees extend much farther than that of annual crops, water is able to permeate the soil with more ease, leading to less waterlogging and runoff, reducing the chance of erosion.(Laffan 2020) Trees have the ability to take up water in deeper layers of the soil that cannot be reached by the crops, this is significant as nutrient rich water that would otherwise be lost to ground water is recirculated back into the system. The canopies of trees act as windbreaks, lowering the rate of evaporation for the surrounding vegetation, mitigating the effects of droughts. (HĂźgel 2017) Canopies of trees also act as a shelter, which increases animal welfare and promotes biodiversity. By allowing trees to be a part of the agricultural landscape, farmers have the ability to diversify their income sources. For example trees can provide fodder for livestock, food through fruit and nuts, firewood and timber. As the case studies show, agroforestry is an a flexible concept that can be adapted to the varying plot sizes and climate biomes of West Nairobi.

Since 1840 the farm has been an important producer of high quality merino wool and for the last three generations has implemented Agroforestry principles. (Laffan 2020)The farm is run holistically with an emphasis placed on preserving and enhancing the natural resources of the farm. The additional 260 000 trees, consisting of native eucalyptus and exotic pines as well as NH hardwoods, provide much needed shelter for the sheep and other livestock from the extremities of both summer and winter. The trees help reduce wind chill that would otherwise cause severe loss of young stock during winter. (Laffan 2020)

The fast growing pines are harvested each week depending on the demand and the shade providing hardwood trees are selectively chosen and milled for timber purposes. As well as being essential to the economic sustainability of the farm, the trees help create a resilient landscape.

Many farmers in Kenya need to have multiple sources of income in order to survive.

Fazenda da Toca is a 2300 ha farm in the state of Sao Paulo, Brazil. Since 2009 it has become a large scale organic production hub that currently has four primary agricultural operations all managed independently in partnership systems but with the same underlying philosophy of land regeneration. These are; laying poultry, dairy cows, grains and agroforestry. (Fazenda da Toca 2019) By understanding that all these agricultural systems can work in symbiosis, a sustainable and regenerative productive landscape is created that has a diversity of income sources. The farm has implemented an Agrosilvopastoral system, it

has done so by combining dairy cattle, grains, avocado trees and honey. The main economic source for this system is milk production and by combining the cows with other forms of agricultural production, multiple benefits have been realised for the farm. (Fazenda da Toca 2019) The additional tree coverage provides shade, silage as a by-product of sorgum processing and importantly additional high value products such as avocado, timber and honey. This diversity of production encourages a variety of ecosystem services such as, bee pollination, nutrient recapture, water retention and importantly carbon sequestration.

https://fazendadatoca.com.br/
The drawing above is a representation of the pasture area in Fazenda da Toca. The paddocks are dispersed in between rows of forests planted in a north-south direction, this provides shade for the cattle throughout the day. Two types of avocado trees were chosen, Fortuna Avocado and Avocado Hass, so that fruit can be produced throughout the year. Different varieties of eucalyptus trees were planted alongside the avocado trees to ensure a permanent supply of flowers, for the production of honey throughout the year. (Fazenda da Toca 2019)
The architecture of the grain production is much the same as the pastoral system with the only difference being, in the summer there is a cultivation of sorghum intercropped with lab beans and in winter oats is planted alongside millet. Crop rotating within the structure of the trees, allows the soil to recover and replenish it’s nutrients, ensuring a resilient and productive future for the farm.
Much like the wester regions of Nairobi, the province of Sao Paulo has been subjected to intense land degradation. Farms like Fazenda da Toca provide an environmentally beneficial and economically viable alternative to the destructive practices of deforestation, monoculture and stripping of resources.

The Picaso Food Project is a communal experimentational food garden that uses principals of Agroforestry to provide a biodiverse public garden that also acts as a pantry to the city. It is essentially a 4500m2 public park where the trees other than providing an aesthetic function also produce food and shelter for the surrounding urban environment. (FRUTTORTI DI PARMA 2019) The park is still young and will take more time to develop fully, however it was designed to grow into a forest with seven distinct layers, mimicking a natural forest environment.

The Picasso Food Forest is an important public amenity that provides the residents of Parma with the opportunity to have a deeper interaction with nature, healthy eating habits and a better understanding of food growth. With active participation from the surrounding community the forest has contributed to the development and fostering of the neighbourhood community.

SLOW TOURISM Towards sustainable tourism development of West Nairobi
Defining slow tourism Globally, tourism is a fast-growing industry with diverse products link to environment, history, and culture. With tourism’s strong connection with nature, the impacts of tourism in the environment are more remarkable. In this regard, new forms of tourism are tied up with sustainability. Ecotourism, cultural, heritage, health and medical tourism are tourism types motivated by environmental protection, but at the same time, personal and social well-being (Assaf, Baloglu and Oh 2016). Emerging from the same driving factors was slow tourism, a new concept originating from Cittaslow movement in Italy in the late 1990s. In its early notions, the ‘slow’ in slow tourism was emphasized through ‘movement’ and ‘consumption’ (Go and McGrath 2106). Dickinson and Lumsdon (2010) define slow tourism as “a conceptual framework that involves people who travel to destinations more slowly overland, stay longer and travel less and who incorporate travel to a destination as itself an experience and, once at the destination, engaged with local transport options and slow food and beverage, take time to explore local history, culture and support the environment” (pp. 1-2). Lipman and Murphy (2012) distinguished ‘slowness’ in consumption through slower travel, less transport and mobility. These definitions explore slowness more in human travel behavior and why people engage in slow travel. However, the research focuses more on slow tourism’s contribution to a more sustainable development of landscape, and in the case of Nairobi’s peripheral areas, to regenerate and retain the identity of its territory amidst challenges in relation to climate change and urbanization.

with multiple backwards and forward economic linkages. Most of the country’s tourism is nature-based and about 10% of its land area has been appropriated for wildlife conservation and development of ecotourism based on wildlife viewing. Popular National Parks such as Lake Nukuru, Nairobi, Tsavo, Masai Mara, an Amboseli are the main gateways for safaris. Although Kenya’s tourism heavily relies on wildlife, the coastal areas and unique indigenous cultural heritage also provide comparative advantage for tourism development. However, there was a decline in tourism arrival associated partly with the country’s political turmoil and reduction of the quality of Kenya’s tourism product. There was unplanned and disorganized spreading of hospitality facilities resulted in severe resource degradation (Akama 1999). This, together with a lack of competitiveness in tourism product offerings with other African countries, has led to attaining lower levels of tourism demand in recent years. Kenya’s capital, Nairobi, also receives decent numbers of visitors because of its historical and wildlife attractions. But the urban core has been transformed to a highly commercialized area and preceded to a modern culture supported by leisure products including casinos and nightlife. Thus, the peri urban areas of Ndenderu, Kikuyu and Ongata Rongai are seen as the new tourism locations, as the areas carry several popular attractions (e.g. Ngong Forest, Kiserian Markets). Interesting landscapes, growing horticulture and floriculture industries and indigenous practices were also discovered during fieldwork. Within the slow

Rural tourism in China has been an effective catalyst of promoting industrial reconstructuring, agricultural development and rural upgrading. In the early stages of the country’s rural tourism development, the government encouraged establishment of village-level tourism programs to maintain ‘rurality’ of the village landscapes, local customs and culture, which are the key components of rural tourism in Suichang (Huang and Ryan 2013). Suichang is a small agrarian village located in Lishui, a mountainous region of Zhejiang Province. Suichang is known as the origin of both Qiantang and Our rivers and for its picturesque forest landscape, gold mine and quality tea products. In 2005, the governor

carried out rehabilitation at the village level, starting with dilapidated village houses. Many of the houses were abandoned as locals migrate to cities for better economic opportunities (Huang and Ryan 2013).
(https://www.portfoliomagsg.com/article/luxe-life-in-beijing.html)
Beijing-based architecture firm, Chiasmus Partners, designed a plan to restore the village with the slow tourism model, akin to ‘pensione’ concept in Europe, referring to Italy’s small hotels and guest houses (Kalkreuth 2019). As some mass tourism projects caused displacement of locals and villages converted to gentrified inns, the redevelopment of Suichang Tea Garden Village aims to retain history and traditions of the villagers. Original houses will be renovated to add extra rooms for hospitality, as the locals will remain in their own homes. One important aspect to maintain the identity of the landscape is avoiding ‘cement plus steel’ rural building style to guard against visual destruction. Aside from selling local produces like tea, bamboo shoots, honey and herbs, the locals will also be part of hospitality teams, for instance, acting as chefs and tour guides. This becomes possible through establishment of shareholding cooperative organizations (or village-based associations). In this autonomous enterprise model, households need not to obtain individual business licenses. The whole village will work as a unified corporation, as tourist will be received unanimously through cooperative association, and then allocated to individual homes. The restoration of the houses is tied in a sustainable economic model, where individual households turn into hospitality operations offering accommodation, food and beverage (Huang and Ryan 2013). In a county scale, the government created a unified brand of ‘Suichang Commune’, a tourism marketing strategy that carries the traditional rural image of Chinese villages and farming activities in the 1950s. The brand was applied in different levels, at the county level, village level and individual households, to convey the authentic nature of Suichang landscape (Huang and Ryan 2013).

Ndenderu’s Tea and Coffee Plantations
(https://www.pinterest.co.kr/pin/144959681736529160/)
Together with horticulture, coffee and tea constitute over half of Kenya’s economy in total trade export earnings (Karugu 2006). The district is suitable for farming because of the combination of fertile soil, suitable climate and well-developed infrastructure. Tea production continues to grow as Kenya remains one of the leading supplier of black tea worldwide. Coffee production, on the other hand, has been affected by drought and has drastically decline over recent years.
(Google Earth 2020)
Most parts of Ndenderu and Limuru were called ‘white highlands’, derived from the British and Europeans settlers who eventually established residence, coffee and tea plantations, cereal farms and ranches in the area. To date, several coffee and tea farm estates owned by European settlers still operate in Kiambu incorporating tourism such as tours and homestay. Such tours enable visitors to pass through various small towns, an opportunity to showcase Kenyan rural life. Other small-scale farms are also operated by the locals that continue to use indigenous practices in growing and harvesting tea and coffee products.

The ‘Suichang Commune’ framework can be well applied in the development of tourism in Ndenderu to showcase rural landscape, early colonial village life, and local’s traditional farming methods and produce. Further, the rehabilitation of villages, in the case of Ndenderu, small scale farm estates can meet the basic needs of dining and lodging at locals’ homes.

Lower Austria has more than 2000 years of floral history, and ‘garden tourism’ attracting 3 million visitors yearly. A diverse network of show gardens was created in Lower Austria to showcase and connect different garden cultures from private gardens, historical gardens, theme parks, adventure gardens, and other emerging garden types. This network operates under the ‘Nature in Garden’ movement, which also conducts activities for landscape development and ‘ecological gardening’. Different garden shows are open to the public and offers inspiration in settings of Austria’s diverse garden types: palace gardens, monastic gardens, and contemporary gardens in private homes (Nature in the
82
Garden 2012). The initiative also aims to raise awareness in making gardens and green spaces more ecological following set of principles and guidelines: • Banning use of peat, pesticides, chemical, synthetic fertilizers • Growing variety of indigenous, regionally typical and ecologically-valuable plants • Using beneficial insects and ecologically valuable garden elements • Composting, mulching, use of rainwater and other recycling techniques • Growing varieties of plants resistant to diseases and pests • Growing herbs, fruits and vegetables in home gardens
(https://wp.eghn.org/en/die-garten-tulln-2/)
Die Garten Tulln was one of ‘Nature in the Garden’ showcase project in Austria in 2008. The show garden is the first ecological horticultural show in Europe and hosts more than 50 show and theme gardens in a 10-hectare site located in Tulln, Austria (Nature in the Garden 2012). The garden became a permanent facility and now includes other facilities like treetop walk and adventure playground. There are interesting garden examples now in Die Garten Tulln that Kikuyu floral industry can take inspiration from. For instance, The Garden in a Changing Climate grows plants with drought agreeability as rainfall becoming fewer during summer and winter. The plants have lower water needs, and irrigation facilities were constructed to direct flow of water uses to save water. Another type is wood roof gardens that displays greening of roofs strategies that can be adopted to urban environment. More than ornamental value and benefits, these plants are drought tolerant and urban air resistant, and have valuable contribution to cities’ biodiversity. The Earthworm garden shows the importance of natural cycle to improve gardens. Earthworm humus improve soil life and helps decomposting garden and kitchen waste, thus reducing the need for pesticides and fertilizers (Nature in the Garden 2012).

Floriculture has been identified as a niche tourism product under Kenya Vision 2030. Over the last decade, there has been a steady increase in floral export, selling flowers to more than 60 countries worldwide. The biggest exporter of roses is the European Union, with a share of about 35%, whereas approximately 50% goes to Dutch Auctions, placing Kenya as one of Europe’s top suppliers (Kenya Flowel Council n.d.). In Kenya, roses are grown in greenhouses on large monoculture farms (Benoit 2019). One of the largest floriculture farms in Kenya is Magana Flowers Kenya located in Kikuyu, down south of Unduri Swamp. The farm is operating in a fully hydroponic rose farm composed of 43 green houses and grows 3 categories of roses, in large head-size, richer color and longer vase-life sizes. Despite floral demand and in place facilities, floral industry in Kikuyu is still primarily dedicated for export and has not been tap for tourism purposes (Kuragu 2006). Taking from The Garten Tulln experience, Kikuyu can explore variety of floriculture products that is appropriate in Kenya’s weather. Water scarcity is a big problem in Kikuyu as industries compete for water use. Despite existing system of water towers and reservoirs, water supply system is not established, and domestic water use is predominantly directed from these natural sources. The prolification and dispersed planning of industries also contribute to water pollution. Floriculture is an industry that mainly depends on water, thus types of plants and cultivation must ensure protection of water sources in Kikuyu. Applying The Garten Tulln’s principles of banning the use chemical pesticides and exploring growing plants that overcome climate change impacts (e.g changes and decreases in water supply, increase drought, increase flooding) can be a sustainable solution to Kikuyu’s floriculture industry. Further, investments on rain-fed floriculture and other water recycling programmes will reduce pressure from natural water resource consumption. As Kenya’s weather will not permit all year flower farm display, the gardens can be converted to other uses such as public park, events place and similar to the case presented, garden exhibitions and model projects that can showcase Kenya’s commercial and indigenous floral products and ecological practices.

03_Remaining Maasai IL NGWESI

(https://journeysbydesign.com/destinations/kenya/laikipia-central-highlands/il-ngwesi-lodge)
Laikipia, Kenya
Lakipiak Maasai
In the early 1990s, the Maasai community of Il Ngwesi Group Ranch started to engage in wildlife tourism as a way to improve their livelihood while maintaining pastoral practices. To reduce sole dependence on pastoralism, the Maasai utilized wildlife (or livestock) in the form of community-based wildlife tourism enterprise (Harrison 2001). In the community level, the key benefits of this diversification are obvious in improved social infrastructure and economic security. In the long run, tourism also brought promotion of Maasai culture and preservation of pastoral lands. The co-existence of tourism and utilization of pastoral activities is evident in the case of Il Ngwesi II Group Ranch in Laikipia District, Rift Valley
86
Province of Kenya. Il Ngwesi Group II Ranch is just one of the 29 wildlife tourism enterprises operating in Laikipia, together with other tourist properties of private cattle ranches, wildlife conservancy and forest reserves. Much of the area of Il Ngwesi II Group Ranch is conservancy and in 1996, Il Ngwesi Lodges were built targeting luxury tourist market (Harrison 2001). Cultural Bomas were also constructed separately from the lodges to provide fee-paying tourists view of Maasai life and cultural performances. Today, 60% of the area is set aside for tourism and wildlife, and 40% as grazing land (Harrison 2001).
(http://ilngwesi.com/content/visit/)
Community Based Enterprises Il Ngwesi is centered on community-based tourism and it has yielded positive socio-economic and livelihood benefits for the Maasai community. Through eco-friendly activities, tourism was used to conserve wildlife, uphold Maasai culture and developed community social infrastructures (Harrison 2001). World Tourism Organization identify community-based tourism as a model of tourism development which encourages local participation and benefit sharing. Il Ngwesi is owned, managed and staffed entirely by Maasai communities. Profits from the lodge and donations from tourists provided funds for construction
of school and health buildings, supported school fees and acquisition of land for grazing. Many Maasai women were also given livelihood opportunities in producing beadworks for market sale, set up souvenir shops at the lodge and financial capital to run small businesses (Harrison 2001).
87
(http://ilngwesi.com/content/visit/)
Ongata Rongai’s predominant land activity is livestock farming where majority of the residents, mostly outside Ongata Rongai’s core district, still practices Maasai pastoralism. There are areas where small and medium scale agricultural farming are mixed in communal ranches. The area’s vastness and proximity to Nairobi City provides competitive advantage in expanding meat industries, but also tourism activities. There are several tourist attractions in the area: Ngong Hills, Giraffe Sanctuary and Oloula Forest, but it is the rich Maasai culture that can provide distinct identity to Ongata Rongai in positioning itself as a major tourist destination outside Nairobi.
88
Conservancies like Il Ngwesi are mostly found adjacent to National Parks as they are former group ranches that were consolidated to become wildlife conservancy mixed with sustainable ecotourism activities. The case of Il Ngwesi can be wellapplied in the remaining group ranches that are now subject to land subdivision and privatization due to urbanization pressures. Converting private ranches to conservancies will help preserve Maasai’s pastoralist activities, as well as diversify economic livelihoods by employing Maasai as administrative staff, tour guides, rangers, etc. Maasai’s indigenous pastoralism requires large land tracts, and land consolidation will help facilitate animal movement within conservancies.
Wildlife viewing remains to be the major tourist attraction but research clearly shows that there are other tourism product offers in West Nairobi. Taking account climate change and urbanization challenges, integrated development of ‘slow’ tourism circuit in West Nairobi can be a variant new industry that can mitigate these challenges but at the same time, promote tourism products of landscape and culture unique to Ndenderu, Kikuyu and Ongata Rongai.
(© Loverina Cruz)
Ndenderu’s tea and coffee plantations, Kikuyu’s floriculture and Ongata Rongai’s pasturelands can be merged into one ‘slow tourism’ destination scheme for West Nairobi. The focus will be the improvement of existing tourism destinations and developing new tourism products showcasing each of the area’s major offer. The component can be one integrated infrastructure development of tourism sites to connect them as one tourism circuit. Because all tourism offers are nature and culture-based, slow tourism can be harnessed as a strategy to create interest in rural areas in Kenya. Slow travel itinerary in the circuit can be a solution to growing problems in West Nairobi as it can create growing interest in rural African villages, heritage and culture, improve accessibility and enhance environmental consciousness. Socio-economic benefits will also spread to the local communities.

conclusion.
Since these alternatives generate few or no emissions of polluting substances, human proximity is feasible, and therefore additional programs and uses can be introduced. In most of the cases, energy production usually takes place isolated from the public realm either for sanitary/security purposes or just because of its scale and location is not near to human settlements, for example, the Taichung Power Plant, in Taiwan, a heavy polluter of carbon dioxide or the Gansu Wind Farm in China, the largest wind farm in the world, which in 2015 wasted 39% of its capacity and its isolated location in the Gobi desert, far away from the large concentration of population in the coast prevents the wind farm to address the problem of massive coal production in the countries’ large metropolises (Hernández -New York Times, 2017). When it comes to ownership and/or administration it is usually carried by a public or private enterprise, which means that access to energy can be more sensitive to market logic. New means of renewable energy are making possible to allow people and communities to be more independent from this logic and also to give access

The Hillerød Utility Company set the goal to integrate water purification, biomass, geothermal heat production a recycling station, and test sites for solar and wind energy. The concept was developed around turning a “necessary burden” into a public asset, and investigate how each component creates synergies with other pieces of the puzzle. (Birney, 2020) An important characteristic of the project is the educational factor, which means that clean energy production is visible to the public realm and explicitly demonstrated in specific zones, thus looking for “spreading the message put in practice”. The slopes become Biocorridors, the first layer. This layer articulates the ecosystem around the main
94
wetland and defines the program’s structure. Along these corridors, blue corridors allow water runoffs to be channeled into the wetland zones. The following layer is the zoning, with the water treatment plant as the largest and most centric part, with the different means of energy generation around and with the social/educational components in the center as well as observation decks and pedestrian and cycling paths inside. Another important factor is both the operational and financial efficiency, as Henning Gade, Project Manager of the company states: “We consider it an important task to create a plant that is as financially sustainable as possible. The new plant will generate electricity and
Figure 3. Functional zoning and bio-corridors. Holmes, Damian (2017) Energy, Climate and Environmental Park | Solrødgård Denmark | C.F. Møller Landscape
use wastewater as a resource to a much greater extent than previously. If we can also affect people’s waste behavior, it can further optimize our operation and reduce expenses...” The water treatment plan intervention was conceived as part of the landscape, as the facility seems to emerge from the ground, its rooftop becomes part of the park, and its facades are transparent in order to allow the visitor to see the process of the treatment. (ArchDaily, 2019) Key points: Public space-oriented, Overlapping of programs and uses, Social involvement (education factor), Financial and operational efficiency. These model’s key points can be implemented anywhere but their potential
can be better exploited with a of mix of uses, local cooperation and a strong institution that can ensure that the overlap of programs is creating synergies and where the landscape is thought based on user experience and safety. In the Kenyan context, the diverse potential of renewable energy means of production can facilitate the overlapping of programs to be feasible. On the other hand, the lack of public spaces and ecosystem fragmentation in the periurban area of Nairobi plus its rapid urbanization can increase the possibility that public space as such will be attractive and that the education factor can play a role in the choice of the means of energy production as energy poverty decreases.

02_Case 2 Energy decentralization NAGELE ENERGY MASTERPLAN
2018
Figure 4. Masterplan. FABRICations (2017)
Nagele, The Netherlands
FABRICations and BETA
This masterplan comes from the latest initiative carried by the Chief Government Architect of the Noordoostpolder municipality “Energy Lab Nagele” which comes from the initiative started in 2009 to revive the town through a bottom-up approach and with a sensitivity to the town’s modernist cultural heritage. “Energy is no longer an abstract concept coming from afar, rather it is something everyone could welcome in their backyard” - Fabrications, 2018. It aims to “secure a sustainable future by making Nagele energy self-sufficient through an innovative system of energy collection and storage. Something critical for the conception of the concept is the reciprocal development of collective facilities in the village core and large- scale energy production beyond
96
the forest fringe. (FABRICations, 2018). FABRICations’ proposal utilizes four different means of energy generation, wind, solar, biogas and algae farming. Not all of them are there to generate electricity but they have a particular purpose: Biomass: Processes both green and organic waste to generate energy specially for domestic use; Algae Farming: Produces heat that will be used to warm swimming pools and green houses. Key points: Energy decentralization/Communal production, Diverse means of energy production, New energy and a recovered landscape as catalysts for innovation and entrepreneurship, Energy and public space synergies (One motivates the other one).
Figure 5. Scheme FABRICations (2017)
In the context of the periurban area of Nairobi, this example can bring some ideas that can be applied. Firstly, the decentralization of energy and communal production, Kenya has a rate of 82% of its population living under energy poverty or no access at all (Moss, 2017), and the construction of an electrical grid may require an additional amount of resources that make it harder to found, and also to supply in distant contexts. Energy decentralization is feasible under the context of a sunny country through solar energy and also in an agrarian context, through biomass Diverse means of energy production is needed both to secure energy but, specially on the case of biomass, to prevent a counterproductive effect for a clean
environment. Biomass is specified due to its abuse can lead to deforestation or environment destruction (Field, Campbell & Lobell 2007). Energy has always been a driver for production and industrialization, it is needed in order to thrive. Having energy, among other aspects, in the center of development policies is a must. Clean energy can be attractive to people and, as in the first case was mentioned, its location of production can be a public space as well. An important factor that is more explicit in Nagele is that the energy produced is used to operate the public facilities, this principle can also be used in Nairobi and anywhere.

AGER Group
The Gowanus Lowline Competition, launched in 2011, had as its main interest the value of the urban development of post industrial urban lands (e-architect, 2011), studio AGER’s design approach is based on a healthy working industrial ecology where wastes are recycled, resources conserved, and community regenerated based on the existing foundations of a site. Among the language used for the site bioremediation “Curtain Mattress” is the one that relates to new energy generation mechanism (Buslter Editors, 2011). This process is carried out by a mechanism called Microbial Fuel Cell (MFC), which is a mechanism that uses contaminated soil as a fuel to generate energy.
98
The Curtain Mattress is composed by a geotextile retaining wall, a sliding walkway, and the LED display (woven into the geotextile membrane), integrated with the MFC. This membrane will be powered by contaminated water, and the greater the contamination levels the more power generated for the LED lighting. The LED lighting becomes a performance indicator, which informs passerby of the level of soil contamination, thus becoming also an indicator (Buslter Editors, 2011). Bruce Logan (2013) suggests that Microbial Fuel Cell can be better applied to wastewater treatment by distilling ammonia out of water, so that concentration
Figure 7. Microbial Fuel Cell sceme. Ross, Philippa (2011)
gradients could be established with ammonia to generate power in a systems similar to a flow battery. Logan also states that 5% of the energy produced in the United States is used for water infrastructure, he proposes that a truly sustainable mechanism that generates energy through it can help the wastewater to be not waste anymore. Among the main challenges is to build the enormous quantity of liter systems required for this process, something that hasn’t been done yet, therefore this lack of experience means that we can’t have a clear perspective of the Microbial Fuel Cell system.
The Microbial Fuel Cell is a promising mechanism that could be applied in any country on Earth once its challenges have been solved. The way is implemented in the Gowanus Lowline is interesting as an indicator, but it implies that in order to operate in another scale the river has to be polluted. This is not what the designers mean certainly, but its application must be beyond that, in cases such as wastewater coming from large urban centers, it could be quite useful to generate energy in wastewater plants that will provide energy to such plants, as professor Logan (2012) mentions.

state can’t completely cop with since it has little resources. This research provides two concepts that can be applied in cities with similar economical conditions as Nairobi: Decentralization and Program Overlapping. Decentralization: As in the case of Nagele, it helps to those communities in energy poverty far from the great urban cores, this reduces the cost of the construction of the grid and also may make them more independent of companies, since many live in a situation of informal economy, incomes are not constant and some people cannot afford to pay electric bills. In the context of a city like Nairobi, sun is always present, therefore ensuring a yearround generation. Program Overlapping: In this concept, two aspects are included, one is the diversity of mechanism of generation in a single place, and the other one is roughly program overlapping. In the three cases mentioned, program overlapping is the essence of their idea. In the Hillerød and Nagele cases, there’s not only a diversity of mechanisms in generation, but also the facilities become a public asset. In the first case, it is more public space oriented, and it plays an educational role as well, in the case of Nagele, energy production also is inserted in the public realm but with a more explicit integration of synergy, for example, agriculture in the site produces material for biomass energy while algae farming helps to heat the water sports facilities. Program Overlapping is also present in the Gowanus Lowline case, as it serves as an indicator of the levels of pollution.

Urban agriculture has been a way of securing food and income for a large group of people who did not have the chance of being recruited in an official employment. (Omondi 2018) Therefore, a lot of families in Nairobi who have in-migrated from rural areas to urban centers in search for income opportunities, urban agriculture has been their mean of bringing their agrarian practices in to their environment. Hence, chicken, sheep and livestock are found roaming through the streets fragmentally, and private farming plots are scattered along the roads. Nairobi’s urban farmers use their crops for both, economic income and their own household use to feed their families. The urban poor women are mostly the ones

As most, if not all, of the informal dwellers in Cairo originally come for rural areas in Egypt as Upper Egypt and Delta, their original livelihood practice is farming. Hence, the project purposes to bring farming back to life in various areas and settlements in Cairo, especially for low-income communities to provide them selfsufficiency and food security. Schaduf started their project of installing soil-less hydroponic farming on the rooftops of the Cairo’s compact urban settlements. (Dalakian 2012) Sherif Hosny, the cofounder of Schaduf and the project, explains that Cairo holds a massive amount of vacant rooftops, in addition to high rate of unemployment, and its climate is also very suitable for farming productivity.
104
These factors together make rooftop cultivation a perfect intervention so people would make better use of their roofs as a new productive and social space for building inhabitants to meet and children can use the space to play. Additionally, as proximate buildings start to grow plantations on their rooftops, the plants absorb the CO2 emissions thus decrease the temperature of the areas’ microclimate. (KALAN 2014)
Š GIZ Š Valentina Cattane
This method of urban agriculture is very applicable in Nairobi, as the city comprises the same factors of unemployment, suitable climate, and unused rooftops in areas of flat-roof buildings. This application would strongly support the urban poor in Nairobi to self-sustain their food production. Besides, as Nairobi faces very high temperatures in summer, the intervention would regulate the climate in the involved areas.

The Food Garden Rotterdam was designed on a former industrial wasteland, for a main target of providing the vulnerable individuals and families with adequate, maintained food security. The project is of 7000 square meter area, which grants the vulnerable and unemployed individuals potentials for volunteering and participating in the cultivation and production process in the garden. The harvests of the garden could then be used by people in need as the homeless, the food bank of Rotterdam, in addition to the volunteers. The volunteers profit from their productions as they can sell them around, which also reinforces their social networks and cohesion. (Inherit 2017) The project creates strong social

As Nairobi comprises a huge percentage of urban poverty and unemployment, a similar project within the city’s grey urbanism would maintain food accessibility to the low-income communities. Furtherly, a lot of vacant spaces in-between buildings have great potentials to turn to productive spaces where the diverse unemployed including youth, men and women would coordinate in producing yields for the whole community. The way the gardens gradually interweaved between the buildings, connecting them with aesthetic and productive spaces is very inspiring to understand and apply within the Nairobi urban settlements.

03_Rural-Urban Integration SONGZHUANG ARTS AND AGRICULTURE CITY Beijing, China
On the Eastern periphery of Beijing, the project introduces a new approach of intertwining rural life within urban settlements. Agriculture is already a crucial part of the Songzuan’s local economy, as about 55% of the area consist of agricultural lands. However, rapid urbanization started destroying the agricultural plots, declining the agrarian productivity. Thus, the project aims to maintain the food security of Beijing’s urban fringes and generate self-sufficient communities. To do so, the plan allocates farmlands and agricultural productive landscapes right in the center of the project, while surrounded by the proposed urban developments on the productive lands’ fringes. (DeOliveira 2017) The proposed community

Inhabitant were relocated within their neighborhoods with their same neighbors and social networks, and the existing farmland were integrated into the plan. The new housing system of clusters is connected with surrounding services. (SASAKI 2012) Reviewing this project is insightful for understanding bigger-scale planning of agro-urban settlements and rural-urban integration.

The project’s intention of interlinking new urban settlements with existing and proposed landscapes is great, however, it could have been more suitable for the area to use the existing settlements and propose new units within the existing landscapes, instead of creating a whole new plan from scratch and bringing it in to the area. By attaining that, it would also be applicable within the context of Nairobi’s peripheries to cluster the existing and proposed settlements within the area’s productive landscapes.

Urban Agriculture within Nairobi is often recognized, however, in very inefficient and unhealthy means. As most of the inhabitants of Nairobi and its peripheries are originally farmers, interpolating community food gardens, farmlands, rooftop farming, allotment gardens, backyard plots and other productive landscapes encourages the former farmers to relive their main occupation. Beside the ongoing privatization of the agricultural plots in the peri-urban areas, the conjoining of communal gardens of different scales reinforces the social inclusion of the community. As Nairobi comprises a huge group of marginalized urban poor, homeless and unemployed, these urban agricultural interventions help turn their lives to more productive and socially inclusive people. The urban poor secure their access to food throughout their own cultivation and production. Meanwhile, selling their products maintains an economic income for them. The homeless people have access to the public products and yields of the gardens. Besides, the participation

Socio-economic Benefits of Biodiversity Kenya’s fast-growing economy is driven by sectors (agricultural ~34% of GDP and tourism ~9% of GDP) that are mainly dependent upon the conservation of biodiversity (Thornton 2010; World Bank 2019). Thus, failing to conserve biodiversity not only has ecological impacts but also significantly damages the socioeconomic environment. It becomes important for Kenya to maintain biodiversity not only in the rural regions but also in its main cities like Nairobi. A lot of ethnic communities (such as Masaai, and Kikuyu) in Nairobi are dependent

Rethinking Coexistence Studying the growth of Nairobi, it becomes clear that the city might not be able to sustain its biodiversity. It is important to study how different approach towards implementation of projects, design and policies can open paths towards rethinking coexistence between man and nature. To start thinking about coexistence between man and nature, it is important to point out where the current system fails. The degradation of the natural systems can be linked uncontrolled urbanization, however, these factors are backed by lack of Š USGS/NASA

can be improved to have a positive impact on the socio-economic environment of Nairobi. In addition, the paper acknowledges the need for growth of Nairobi, and investigates how the growth can be sustainable through these different approaches.

01_Rethinking Community Participation
Failure of top-down approach The first approach concerns the relation between micro-meso scale ecosystems and different communities directly or indirectly dependent upon it. With a rich rural background, many of the communities in Nairobi – such as Kikuyu (farmers in the highlands), the Masaai (pastoral farmers in the savanna) - have been living as a part of the ecosystem for centuries. However, suffering from a top-down approach, the policy-making process often overlook many of these ecosystems and the needs of the communities dependent upon them. With no strict land use policies regarding these ecosystems the agricultural valleys are transforming into residential settlements, the wetlands are consumed by industries and greenhouses, the forest are cut down for land, the pastoral grounds are being fragmented for new housing societies. In some cases, the land is overtaken by informal settlements. The loss of the ecosystems has greatly affected the communities who have been collectively using the land in a sustainable way.

Neglected impacts lead to large consequences The impacts from the loss of ecosystem are not only ecological but also social and economic. Communities suffer by losing their means of income, their way of living, traditions, and culture. With the fear of never being compensated for the loss of ecosystems, many of the communities are selling their ancestral lands and moving away. Taking advantage of this situation, the land is being bought private investors who tend to develop it for the higher-income populations socially excluding and marginalizing these communities. If they don’t move away, they are forced to find a new way of living and income. While some people
manage to benefit from the change, majority fail to adopt and recover from the ecological loss.

Social awareness lead to big change Within the context of a large urban city, the project shows recovery of a loss mangrove ecosystem, and how urban development can be combined with nature conservation through community involvement. As the city saw rapid urbanization, the ‘protected’ mangrove forest was cleared for new real estate development. Along with new luxurious buildings the site also hosted growing informal settlements. In 1980s the government recognized the importance of the lost ecosystem and started taking actions. The Mello Barreto Education Park was part of this initiative along with two other projects - the Peninsula and Gleba F. Together these projects were aimed at recovering the lost mangrove forest,

preserving the belt around the lagoon, purifying the water, educating the locals, and improving soil quality (Herzog and Finotti 2013). For the creation of the park, the local authorities teamed with the resident associations (ACIBARRA) in creating social awareness on importance of indigenous ecosystems. The team worked on the process of ecogenetics – the recovering of landscapes using specimens from the original ecosystem (Chacel 2001). An innovative approach at the time, ecogenetics proved to help raise social awareness of indigenous biodiversity and its aesthetic potential in natural landscape (Nassauer 1997).

Involving community In the context of Nairobi, the park sets an example of how communities can get involved, be educated, and help in recovery of the ecosystems around them. The parks success is credited greatly to the involvement of the resident association. By spreading awareness of the indigenous plants and wildlife, the locals realized the importance of the lost ecosystem and the positive effects it can have. With the recovery of the entire Lagoon belt, the locals were able to have access to cleaner water, better sanitation, improved flora and fauna. In doing so, the park not only served an ecological function but also a social one (Herzog and Finotti 2013).
Creating a resilient boundary Sitting on the edge of the Tijuca National Park and the Lagoon, the strategically placed parks creates a soft edge between the urban and the nature. While providing many social recreational spaces and educational service, it is less threatened by the infrastructural development and protects the National park from the growing urbanization. Similarly, Nairobi has a lot of potential for such strategically placed projects that can be develop into an indigenous ecosystem while protecting the area against aggressive city expansion

02_Rethinking Natural Values
Decentralizing governance Since two of the main protected areas (Karura Forest and Nairobi National Park) in Nairobi were gazetted long before the independence, today these areas are under the strong pressure of being dominated by the uncontrolled urbanization. Karura Forest
The management of these areas are under different government agencies. Despite the law being clear about restriction on development in any protected areas, these agencies are often pressurized or incentivized to sell the land to the government to allow building new infrastructure in the protected areas (Welz 2019). This is possible as the established centralized management can overlook the needs and values of the protected areas and serve in favor of the government decision. Often there are many protests from the environment protection agencies regarding the decisions of the government, but they are left unheard. Without the decision-making power the environment protection agencies and other stakeholders often turn to environmental law which often obscured the interest of nature behind the developmental and human interests (Sands 2012; O’donnell and Talbot-Jones 2018). The approach of decentralizing the management has its advantages but it comes with a lot of challenges. It needs a restructuring of the institutional framework, a new way of protecting nature under law, and identifying stakeholders with their roles. With the approach the goal should be not just protecting the area but making it sustainable and beneficial for all the stakeholders involved.

Whanganui Iwi
Human rights for the river The case of Whanganui River is one of the first natural resource to be given legal identity, with rights and duties equal to a legal person (Davison 2017). Under the Te Awa Tupua act 2017, a treaty was signed between the Maori tribe of Whanganui and the Crown. This Act creates a new governance framework for the river, while recognizing its entire 290km stretch, its catchment area, and metaphysical elements as a whole entity (O’donnell and Talbot-Jones 2018). The case presents a new governing framework consists of Te pou Tupua, who is responsible of acting and speaking on behalf of rivers well-being. Acting as a guardian, Te pou Tupua consists of two representatives working together, one from the crown and one from the Whanganui tribe. In addition to Te pou Tupua, the new legislation offers the support of and advisory group (Te Karewao) and a strategy group (Te Kopuka na) which will develop, review, monitor and
120
approve implementation of strategies. The strategy group consist of up to 17 key stakeholders of which some are; different tribes linked to the river, representatives from the energy and power scheme, tourism, conservation, wild games, and government representatives. The focus of this strategy group is collaborative planning and management of river catchment area (O’donnell and Talbot-Jones 2018). The case is an example an inclusive framework rather than an exclusive one. It expands the legal framework creating a nested management community (TalbotJones 2017). In addition to the legal rights, the Crown is responsible to support the Act through a series of payment.
Inclusive framework The case can claimed to be successful as it changes the management system through legislation with minimum disruption and settles the long standing claims of the Whanganui tribe (Talbot-Jones 2017). The fact that the Te awa Tupua Act is created on a national level also helps with creating a powerful alternative institutional arrangement, which is mutually accepted by both the crown and the tribe, while simultaneously decentralizing the authority by engaging also engaging series of actors, stakeholders, and communities (O’donnell and TalbotJones 2018).

Apart from creating a strong legislation, the act also recognizes and respects the Maori relationship with nature. The Maori view nature as an ancestor, and with the Act the government has gained support of the local communities in protecting the source of water. The river is source of tourism, games, energy, and domestic water. By this act the government secures its supply of water (Iorns Magallanes 2015)

Using this case as an example the government of Kenya can introduce a more inclusive framework and institution that is serving the interested and values of multiple key stakeholders. Many of the protected land has ancestral ties to the communities such as Kikuyu swamp, Oloolua forest, and Nairobi National Park/Savanna. The government of Kenya can greatly benefit by working with the communities and tribes in protecting these areas. It can be productive for the government as it reduces the number of oppositions, engages with every stakeholder, and keep the metaphysical value of the land intact. The implementation of such a framework can be challenging in the bureaucratic environment of Kenya, however it is essential to decentralize the control over protected areas and recognize their values as more than open land. Working with local communities has been proven successful for the Kenyan government when they trained the Masaai to protect the wildlife from poachers rather than hunting them. (Coren 2014)
The tribe have a long history with the river, as they have been its guardian for over 700 years.

03_Rethinking Urban Spaces
The focus of the policies regarding wildlife and nature has been on the areas with the least human presence. Yet with the acquired data, Tyrrell (2019) and his team show that certain wildlife can be higher in areas with substantial human presence. For example, the fragmented green spaces of Nairobi (Urban parks, forest reserves, national parks, and as well as the residential gardens) together hold as many species of birds as the Maasai Mara National Reserve (Tyrrell, Toit, and Macdonald 2019). Subsequently the green spaces in areas with more human presence are left untreated and slowly eaten away by built environment. The urban spaces get more congested creating climate change, pollution, waste problems, and traffic jams. As the city grows, residence move away from the central business district (CBD). More traffic jams are caused as residents commute daily for more than 2hrs to reach CBD (Wairimu 2019). The re-drawing of Nairobi’s boundaries, extending it numerous times indicates the uncontrolled growth (United Nations 2009). With a binary vision of nature and urban, the city fails to protect its green areas, improve living quality and uncontrol the urban growth.

Fragmented green areas A new city plan, strategically integrating green spaces into the urban environment is one of the most important approach towards coexistence. Due to uncontrolled growth of Nairobi, its once planned layout has now turned into a fragmented landscape of natural habitats, informal settlements, protected areas, residential, and commercial.

A long term vision pivoted around nature The Tirana 2030 is a vision of new era for the city of Tirana, which has been approved by the city council. With the plan the architect aims to control development, create improved infrastructure, incorporate green corridors, and enhance urban spaces. The plan follows the main theme of reconquering the landscape through a balance between the city and nature (Stefano Boeri Architetti 2017). Under the central theme the plan uses the natural dimension in several different
124
ways. New continuous orbital forest is created around the city, which includes protected parks, water bodies to preserve biodiversity, ecological corridors along the rivers, and a smaller orbital forest for mobility. The larger orbital forest will dictate the new development taking place. While the smaller orbit near the center will triple the green spaces in the city center. The project plans to launch new small urban centers near the periphery, extending the network of services while reducing the chaotic density of the city center (Stefano Boeri Architetti 2017).

Nature guiding the urbanization Compared to the existing situation, the plan significantly reduced the forecast development in favor of accessible green spaces with mix activities. It uses the orbital forest and other green spaces to restrain urban sprawl and guide the future developments. With strategic spatial projects it activates many of the urban spaces and tries to create a balance of urbanization throughout the plan. Using a large green structure Nairobi can connect its park and other green spaces, creating a continuous flow for the nature rather than being choked by urban spaces. This continuous flow can also help with the traffic problems of Nairobi.

The project also demonstrate how Nairobi can develop its peri-urban areas through a network of new urban centers without damaging the landscape. It also helps with reducing the congestion in the CBD. The ecological corridors along the river help purify the water and keep the biodiversity of the area. Nairobi’s growth is unavoidable, however learning from such plans and visions Nairobis’ urban development can be guided and integrated with the natural landscapes.

After independence, much of the public land in Kenya was privatized and given away as briberies when the government needed favors (Films for the Humanities & Sciences, Group, and M-Net 2010). Today, the rapid growth of Nairobi’s urban population is increasing pressure on land. With high property prices in the city and the availability, low prices and flexible land-use policies in the outskirts, peri-urban Nairobi is experiencing large-scale landscape transformations (Aggrey Daniel Maina 2010). The sprawling urban development is engulfing the remaining natural forests in the peripheries of Nairobi. During our fieldwork, we noticed the inhabitants are eager about the new opportunities that come with urban development, forgetting about the importance of the natural land. Forests across the globe provide essential ecological, environmental and social amenities, and many people depend on forest resources for daily survival (Schusser 2016). Akshay Vishwanath, a Friends of Nairobi National Park board member, states that the “rapidly growing and polluted city does need ‘lungs’ to provide clean air, a filtration system for clean water, and a biological system for the insects that

They also offer long-term ecological and environmental benefits such as land protection, climate resilience and water resource management. In the meantime, the planting and upbringing of the forest strengthens and empowers the community, creating a sense of pride, ownership, and stewardship that connects the people with the land. This essay aims to demonstrate that in social forestry, people build and protect the forest, and in turn, the forest protects and gives back to the people. Social forestry pays attention to the needs of the population and gives the community the power to act upon these needs. It creates an understanding of the importance of the forest, both symbolically and environmentally. It is this synergic interaction between the

Like peri-urban Nairobi, urban development and land-use changes in South Gondar, Northern Ethiopia are also threatening the function of ecosystems and biodiversity. The forests that once covered the Northern Highlands of Ethiopia have succumbed to the pressures of population growth, and the nearly the entire region has been cleared for agriculture and cattle grazing (Bahnson n.d.). Less than 3% of the native forests remain intact (Bahnson n.d.) and these last forests are found in small patches, each centered around a church (Cardelús et al. 2017). Belonging to the Ethiopian Orthodox Church, these forests have managed to persist over the years as they are considered to be sacred places, with the church
132
acting as “shadow conservation” (Cardelús et al. 2017, 726) for what remains of South Gondar’s biodiversity (Cardelús et al. 2017). It is estimated that twenty thousand minuscule sacred church forests are scattered across the Ethiopian Highlands (Bahnson n.d.). However, the isolation and lack of biodiversity of these small forests make them extremely vulnerable to human disturbances and edge effects, with little potential to regenerate (Cardelús et al. 2019).

A pilot project was initiated by two forestry specialists aiming to educate priests about how valuable their forests are and how to conserve them (Bahnson n.d.). The priests brought forward the idea to replicate the inner wall, that forms a courtyard around the church, to build a secondary outer wall that surrounds the forest, protecting the forest and its wildlife and giving it space to expand (Bahnson n.d.). Local villagers, who care deeply for the church, volunteered to collect stones from the surrounding agricultural fields to build the new wall (Bahnson n.d.). Since then, this idea has been replicated to conserve many church forests across South Gondar.
The church forest is a form of “community-based protection” (Klepeis et al. 2016, 715), where religious practices require local communal land that is effectively protected due to external institutional traditions (Klepeis et al. 2016). The forests are vital in protecting the church in the same way that they are protected by their relationship with the church. The church forests already behaved as a community gathering point, however the conservation of them brought new meanings as an ecologically important place as well as a symbol biodiversity conservation. Culturally important and respected institutions in peri-urban Nairobi, such as the church and education, be also used to protect regenerate the native forests.

Transylvania, Romania

The history of Transylvania’s forest declining forest cover is similar to that of Kenya’s. For centuries, Transylvania was a prosperous region due to its rich natural environment (Akeroyd 2016). The Saxon Villages formed farming communities, where the villagers used sustainable and traditional methods to live in harmony with the land (Accor 2020). During the communist regime, both the forests and wood-pastures were cleared for large-scale agriculture and timber industries (Drăgan, Mureşan, and Benedek 2019), leaving abandoned deforested rural landscapes vulnerable to erosion and degradation (PUR Project 2016). Today, the farms scattered across the Transylvanian countryside are under financial

pressure and many families are departing to live in urban locations (Accor 2020), as the degrading land no long provides sustainable living conditions. As natural regeneration is insufficient alone to prevent soil erosion and regenerate a biodiverse forest, a social forestry project was initiated to provide tree saplings to the landowners of affected plots (PUR Project 2016). With a strong focus on education and raising ecological responsibility, local school children plant trees with the guidance from local forestry specialists (Accor 2020). Additionally, an orchard with native traditional fruit is planted in each schoolyard, according to old Saxion tradition, and is taken care of by the students (PUR Project 2016).
Š https://www.mihaieminescutrust.ro/en/heritage/
Like in Kenya, the community respects education and this ssociation to the school helps in protecting forested lands. This social forestry project is needed to help increase economic viability and provide sustainable living conditions in the Transylvanian countryside. While a primary goal of this project is to restore the natural richness of the Transylvanian rural landscape, the reforestation has an important cultural and influential component. The involvement of school children in the tree planting and maintenance of school orchards communicates the cultural heritage to future generations. The dynamics between the local forestry specialists and school children creates a level of awareness and ecological
responsibility that ensures that the forests will be cared for and not abandoned. In this case, social forestry returns to the community by protecting and restoring cultural heritage. By incorporating the tree planting and sustainable land management principles into the education system, the forest acts as a symbol of commitment to the future. The new urbanization in peri-urban Nairobi comes with the development of new neighbourhoods and new schools, where the integration of social forestry into the educational curriculum can be a powerful instrument.

While Bangladesh barely contributes to global emissions, lying at the node of three river basins, this small coastal country is severely threatened by climate change (Rawlani and Sovacool 2011), with increasing frequency and severity of natural disasters (Nath, Jashimuddin, and Inoue 2016). Bangladesh’s coastal mangrove forests historically supported many species of flora and fauna (Hoq 2014) and acted as a buffer to mitigate the shocks of incoming storms (Rawlani and Sovacool 2011). The mangrove ecosystem supplies valuable forest products and food sources and supports the livelihood of 3.5 million local people (Hoq 2014), however, it is rapidly degrading due to competing land uses and various

Moreover, rising sea levels are detrimental to the mangroves (Gilman et al. 2008) and could put up to 30 million people living in the coastal belt at risk of displacement (Belt 2011). With the effects of climate change and the deteriorating state of Bangladesh’s forests placing its impoverished population at tremendous risk, Bangladesh, a pioneer is social forestry practices, can offer valuable lessons to social forestry development in

The Community Based Adaptation through Coastal Afforestation project recognizes that the direct participation from the people, farmers and fishers is required for serious and long-term benefits (Rawlani and Sovacool 2011). This project aims to dually mitigate the impacts of climate change while expanding the livelihood options for four especially vulnerable coastal communities (UNDP Bangladesh 2007). The first component of this pilot project is to mobilize the community in the establishment of large-scale plantations of both mangrove and non-mangrove trees. As fishing and farming are the main sources of income (Rawlani and Sovacool 2011), the second component is to expand the
livelihood options of the community through the “Forest, Fish, Fruit� model (UNDP Bangladesh 2007). This model aims to accommodate landless families and integrate food production and aquaculture into the plantations (Rawlani and Sovacool 2011). This project generates continuous income for the community by producing short-term and long-term resources, and as these income sources require a healthy forest, it simultaneously assures preservation of the forest. The communities, formerly considered a threat to the health of the forests, are now the protectors of the forests. With the people depending on the forest for their livelihood and protection of the land, the forest has a new meaning as a place

Ondiri Swamp, 2020 In the past, the swamp was a lake with clear glassy surface and surrounded by thick forests on its edges. Following deforestation and over-exploitation during the colonial era, the swamp rapidly transformed into a bog-like swamp with floating peat as a result of contaminants. Development of industries and green houses on its shores has escalated the water pollution; despite being a source of rivers that feeds Nairobi City downstream.

Agua Carioca is a project in Rio de Janeiro by Ooze architects. It sought to address water challenges across scales; from one household, through different sizes of favelas up to the city scale. This followed a history of rivers pollution with solid waste and sewage as they passed through the city into Gaunabara Bay. The design addressed poor water quality, scarcity and regeneration of the environment using three adaptable approaches of rainwater harvesting, septic tanks and constructed wetlands. The scalable water management process targeted the remote and informal neighbourhoods (favelas), where the City’s water and sewage infrastructure could not penetrate (Ooze 2017).
158
A series of constructed wetlands and water recycling solutions within different scales of neighbourhoods were developed. Constructed wetlands are proven and effective in treating waste water naturally, through sub-surface flow cells and are cheaper than the conventional treatment plants (Asian Development Bank 2015; Ooze 2017). In 2016 the first pilot project commenced for a household scale system at the home of the famous Brazilian Landscape Architect, Roberto Burle Marx. Planting design was used where wetland plants, tropical trees and bedding plants, accentuanted the function and aesthetics of the project.

A bathroom prototype was installed with the recycling system, whereas a rainwater collection unit was installed for the guest house roof, a new septic tank, a constructed wetland for cleaning the household waste water and a water storage tank that stored recycled water and run-off were also installed. The site is now used by scientists and is open for public exhibitions and research on landscape design, botany and nature conservation (Ooze 2017). Four other designs were developed and a city vision, ranging from one school of about 900 students; a small favela model for 150 homes; a medium-sized favela model for 600 homes and a larger favela model, the size of a district for 20,000 homes.
The designs were systematic and they intergrated all spatial, social, ecological and technical aspects of the sites across scales. They also portrayed potential to transform the entire city on a long-term basis (Ooze 2017). Nairobi has a similar warm tropical climate as that of Brazil; that is deemed favourable for the natural waste water treatment as advocated by this project. The scalable use of constructed wetlands could be used to polish waste water naturally from the households, the greenhouses and the industries found in Kikuyu. This would ensure that the Ondiri swamp and rivers on site have cleaner water. To curb water scarcity, rainwater harvesting could help in water usage.

The Wharf street urban park is a water sensitive urban design project by Syrinx architects implemented in 2008 in Cannington city in Western Australia. The park serves dual functions by managing storm water from the neighbouring urbanized area before discharge into Canning River and also provides user experience and recreation to the area residents (Syrinx 2017). A constructed wetland system consisting of surface and sub-surface flow vegetated marshes, bio swales and cascades is incorporated to ensure efficient management of storm water. The park restores the ecological link between the City and the Canning river enhanced by green corridors consisting of wetland

fringe plants, meadows, shrublands, woodlands and wetland vegetation. Recreational activities are supported by incorporation of picnic and barbecue areas, viewing decks and urban furniture. Besides the western region of Nairobi lacking urban parks for recreation, most of its water sources such as rivers and wetlands are under a serious threat of pollution. The waste water treatment strategies advocated by this case study could be adapted in Kikuyu to treat domestic, industrial and agricultural waste water.

The project was awarded for excellence, research and innovation for storm water management in 2015. The notable outcomes include application of best practice of improving quality of storm water before discharge into the river as per the area’s set guidelines for absorbed particles. By revegetating the foreshore of Canning river, it helped to create new ecologies and sustain the local biodiversity through the matrix of woodlands, wetlands and shrublands incorporated. The cycling and pedestrian paths within the park helped to encourage the locals to explore the new ecologies of the wetlands and river’s foreshore (Syrinx 2017).
The landscape design was innovative, contemporary and functional to link the urban park to the urbanized zone; and added aesthetics to the site. Similar interventions in Kikuyu could be applied where constructed wetland parks could be incorporated to polish effluents from the greenhouses and from Magana flower industries before discharge into the swamp and rivers, respectively. Kikuyu town also lacks an urban park where the local residents can have leisure time. The proposed wetland parks could be designed so as to provide user experience of recreation and education to the park visitors.

White Gum Valley is a suburb in Fremantle in Western Australia comprising of 80 households, that was developed to demonstrate water sensitive strategies from the household scale to the city scale. The approach included construction of a communal reservoir whose source of water was from rain-harvesting; helped the community to reduce on water use by 70%. A groundwater network system helped to boost garden irrigation, rain gardens and provided a source of water for the drip irrigation systems of individual home gardens. An filtration basin that was developed to manage storm water was transformed into a public urban park for recreation (Coorperative Research Centre 2017).
162
Water-wise principles as applied here could be assimilated in Kikuyu. In the urban cores, community reservoirs could be used to supply water to neighbourhoods so as to discourage over-extraction of groundwater through wells and boreholes. Water efficiency and recycling can be realized by harvesting of rain water and by use of drip irrigation in orchards and farmlands in rural Kikuyu to minimise wastage of water. Infiltration basins and rain gardens could be strategically located to manage run-offs from impervious surfaces within the town. Such spaces could be used as urban parks or as plazas where residents of Kikuyu engage in leisure activities.

Josh’s House is an innovative example of a household-level water sensitive urban design approach by Josh Byrne & Associates in collaboration with Landcorp. It demonstrates an exemplary method of water efficiency through rain water harvesting and storm water management; which could be replicated by housing developers in the world over (Cooperative Research Centre 2018). Kikuyu town is urbanizing very fast. The future housing expansions as well as existing ones could be remodelled to adapt into water-wise homes. Grey water could be treated within the lots and recycled to provide water for irrigation of gardens and orchards.
Landscape designs at the household scale could be strategically manipulated to support the water efficiency approach by mass planting so as ‘to hydrozone’ and minimise water demands. Drip irrigation could also assist in micro management of water in irrigation. Permeable pavements were used in the landscape to assist in storm water percolation; a viable strategy that could be applied in kikuyu in transforming most of its walkways, plazas and other impervious surfaces into porous surfaces, so as to encourage infiltration of storm water which will assist in groundwater recharge of the Kikuyu aquifer.

NATALIA RECALDE
Rural-Urban Metabolism
Landscapes in transition The peripheries of west Nairobi are going through an intense process of territorial change where diverse dynamisms are re-structuring the landscape in multiple layers: new economies, social transformation and rapid land use change are paired with ecological degradation. Main drivers of this transition are population growth, internal migration and fragile planning regulations, embedded into neo-liberal economic processes (Abuya et al. 2019). Originally a rural area characterized by agricultural production, extensive tea and coffee plantations provided subsistence for local people. Moreover, crop plantations that supported the livelihood of local rural inhabitants also provided food for the entire city of Nairobi. In current times, land conversion in the Nairobi rural-urban fringe is leading to the reduction of agricultural land to urban uses, reducing the quality and quantity of farming. High demand of housing and profitable real-estate values are the gears of constant land subdivision, transforming agricultural productive land into consumptive residential and commercial uses. Nowadays, the territory of west Nairobi is a metamorphosis of the rural and the urban, a landscape full of tension where traditional rural customs crash with modern urban ways of living. “The urban-rural interface or ‘grey’ area where farming co-exists, often uneasily, with the expansion of built-up areas” is the place of “structural transformation, intended as the transition from largely agrarian economies with most of the population engaged in farming, to a concentration of employment in manufacturing and services” (Tacoli and Agergaard 2017, 7-8). As a consequence of this uncontrollable and unpredictable structural transformation of the landscape, food security and environmental resources are in severe hazard as well as population vulnerable to the threat of climate change.

In order to grasp the complexities of Nairobi’s territorial metabolism is necessary to go beyond the dichotomy of city and countryside, like Brenner and Schmid propose in their article ‘The Urban Age in Question’: “There is no longer any outside to the urban world; the non-urban has been largely internalized within an uneven yet planetary process of urbanization. Under these conditions, the urban/rural binarism is an increasingly obfuscatory basis for deciphering the morphologies, contours and dynamics of sociospatial restructuring under early twenty-first century capitalism” (2014, 751). They also denote that a new vocabulary of urbanization is needed to adequately capture the changing nature of urbanization processes. Consequently, in the context of landscape transformation of Nairobi’s peripheries, the question arises: what design strategies can overcome the urban vs. rural antagonism to potentiate production, industrialization and living in an ecological balanced environment? The selected projects presented in the next section are useful to explore how design interventions can address some spatial, social and ecological issues of rural-urban fringes in Nairobi. The theoretical project Agronica is a vision for a form of agrarian urbanism, where productive land is constant and infrastructure is ‘weak’ and temporary. Following, the adaptation of the traditional rural settlement Kibbutz Hatzor is an example of collective living in agrarian settlements in the twenty first century. Finally, the Women’s Opportunity Center is a model of sustainable constructed and culturally appropriate social infrastructure with a powerful effect in the development of women in African communities.

Andrea Branzi
Dissolution of the urban figure into a productive landscape Agronica is a theoretical project exploring the relationship of city and countryside based on the potential hybridization of agriculture and urbanism. Developed by the Italian architect Andrea Branzi, proposes a model of ‘weak urbanization’, a concept developed as a social critique of the contemporary city on the basis of postmodernist philosophy. The proposal takes into account the variabaliblity and indeterminacy of the the way in which the forces of the economic system shape the landscape, resulting in a diffuse territorial organization that blurres the dichotomy of the urban and the rural.
170
An adaptable, reversible constructive system of light and mobile infrastructures allow the productive landscape to be the primary medium of the urban form. Considering Nairobi’s necessity to preserve productive land capacity and assure food security, his theoretical proposal can lead to explore design systems that support intense forms of production in parallel with high population density, where agricultural landscapes shapes the urban structure.
http://searching00.blogspot.com/2013/10/agronicaandrea-branzibiennale2010.html
http://architettura.it/architetture/20020219/
‘Weak’ architecture Agronica was exhibited through a model surrounded by mirrors, to create the effect of infinite landscape continuity of the theoretical framework of the project. In the model, a continuous and homogenous flat agricultural surface is the background where a grid of pillars frame transitory forms of architecture. The set of colummns support a variety of elements such as pergolas, antennas, solar panels, sunshades and floating platforms, on a productive modular system focused on adaptability and minimun contact to the ground. The system could be expanded or dismantled with almost no impact on the fields.
Buildings are represented as open and flexible containers of a wide set of functions, freed from symbolic and typological architectural connotations and transformed into lighter objects analogous to furniture. This generic and ephemeral architecture and urban form creates a situation of stable uncertainty, a model of ‘weak urbanization’ that denies a classical approach of final state stable perfection. In Nairobi, weak architecture could structure light, adaptable and reversible constructive systems that can adjust to changes without causing damage to the productive and ecological value of the landscape.

A collective productive community The Kibbutz is a cooperative and self-sufficient settlement typology that emerged in Israel in the 20th century. Meaning in Hebrew “gathering”, they were based on social equality and sharing: land was owned collectively, work division managed equally and daily life was shared communally. The spatial layout reflected this organization, having in the core the collective spaces of the community, surrounded by dwelling units and the the agrarian landscape. Due to socio-economic changes and the spread of capitalism in the past decades, Kibbutzs experienced a radical transformation, shifting away from
172
collective lifestyle towards a more private one, centered around the family household and suburban models of subdivision. “The insertion of this privatized and individualized typology into the delicately balanced collective space and life of the kibbutz devastated and damaged the kibbutz’s physical and social landscape” (Segal 2016). The project presented here aims to accommodate new neighborhoods in the existing community of 600 members in Kibbutz Hatzor, preserving the kibbutz’s unique landscape, relation to open space and notion of collectivity.
http://www.arpajournal.net/an-architecture-of-collective-living/
Adapting traditional settlements to contemporary times Conflicting urban-rural dynamics in Nairobi can benefit from collective models of housing and production. In the project, to achieve the goal of combining individual and shared ownership, a neighborhood model (in blue surrounded by a red rectangle) of private single-family homes set within the agrarian landscape is supported by the cooperative structure of the kibbutz (in green). Individual homes continue to be part of the productive cooperative in a model of ‘degrees of collectiveness’, stabilizing the social structure in a gradient that goes from private spaces to shared life.
Balance of private and shared spaces The new neighborhood consist of clusters of houses organizaded in an ‘L’ shape and surrounded by collective square yards, where shared facilities like vegetable gardens, bike parking and play areas are located. While the car is relegated to the perimeter road, houses and open spaces are connected with pedestrian and bike paths. The roof is the framing collective urban element that shapes the cluster, and also have the role of harvesting solar energy. Cooperative housing typologies can be a way to put a stop to land subdivision in the outskirts of Nairobi.

Sharon Davis Design
Socio-economic empowerment Located in a semi-rural town in the peripheries of the Rwandan capital city, this Community Center is an infrastructure for the local community, empowering women through access to knowledge, cooperation and opportunities for growing. The design brings support for Kayonza’s social infrastructure and civic realm by providing classrooms, community public space, a farmer’s market, lodging facilities and more. The goal is to support the development of local capabilities: a demonstration farm teaches women to produce income from the land through organic techniques geared towards commercial production.
174
Earth walls and green roofs make place for animal pens where women learn to raise livestock, along with food storage and processing methods that can be used to run their own food cooperatives profitably. A market showcases the center’s economic potential, where women sell the products produced on site and generate additional income. As many as 300 women participate learning entrepeneurship skills and energizing the local subsitence agriculture economy through female empowerment. As well, Nairobi is in much need of social infrastructure and public spaces to built civic relationships and development.
https://architizer.com/
https://www.archdaily.com/
Context-appropriate architecture The circular pavillions are the main architectural element of the center, structured following vernacular Rwandan villages organizing principles. They provide intimate classrooms with perforated brick walls that allow for passive cooling and solar shading, providing sustainable comfort inspired in indigenous traditional huts. Bricks for the construction of the center were made by the local future users using materials found in the site, transfering innovative low-cost building techniques to women.
Sustainable urban services The project is built with environmentally sustainable features that could be replicated beyond the community center. Rain water is collected from the roofs, filtered and pumped with solar generated power. Animal waste is transformed into biogas fuel for cooking, while composting toilets provide fertilizer for the local farm and market. Experimentation and demonstration of locally appropiate technologies can work in peripherial areas of Nairobi to transform informal urban services into sustainable and locally maintained techniques.

for an alternative for the traditional linear “take-make-dispose� economic model.
Economy (Koech and Munene 2020)
To this end, a closed cycle of materials and energy approach that helps maintain the value of resources (Petit-Boix and Leipold 2018) has been studied and applied in the past decades worldwide. By turning goods that are at the end of their service life into resources for others, closing loops in the industrial ecosystem, and minimizing the waste of materials (Minson 2016), the Circular Economy concept is expected to help maximize economic profit while reducing the environmental pressure. Nonetheless, besides its economic and environmental benefits, Circular Economy also exerts positive impacts on the social aspect, which are usually neglected. In fact, the externalities of the circularity concept can help mitigate many global social issues. Never before are human beings as vulnerable as at the moment under pandemic caused by Coronavirus, because of not only the invisible spread of the virus that affects our health but also the codependency among countries in food and other essential supplies. This raises the alarm about food security. Also, overpopulation and rapid urbanization have caused unemployment and shortage of affordable housing. Particularly in Kenya, over the years, it is believed that the country is exploiting its natural resources in an unsustainable manner (Koech and Munene 2020). Also, with an increasing population living in informal settlements and under unemployed status, Kenya has to deal with the complication of housing and welfare
178
A multi-actor, multi-level, multi-phase, and multi-pattern process The periphery of Nairobi, in strategic location proximity to the capital city yet with many large-scale informal settlements, has a lot of reasons and potentials to focus on the shift to the Circular Economy. This concept is an integration of a variety of disciplines ranging from business to natural sciences (Petit-Boix and Leipold 2018). In the scope of spatial research in this paper, the execution of circular economy can happen in many scales varied from city-scale to neighborhood-scale and in many phases, involve many actors including governmental, nongovernmental and private sectors. For instance, a strategic master plan for the entire area that allocates functional components to optimize the efficiency of the flow of materials should be done by the municipalities. Meanwhile, private-driven varied-scale projects (grassroot initiatives) should be also stimulated to infill the issues left by the top-down solutions. Multiple projects run by multiple actors in multiple scales will become a collective effort to help complete the assignment of the ambition to transit to a Circular Economy in the territory.
Possibility to address social issues in Nairobi This paper is expected to go beyond the common perspective when looking at the Circular Economy and emphasize its externalities (understood here as the capability to address social issues). Three specific social issues will be analyzed and used as examples to reveal its social sustainability potentials other than commonly known environmental sustainability. To be specific, three challenges including unemployment, food security and housing crisis reflect in three cases study and thus applying to the context of the periphery of Nairobi. These cases study are chosen
Kirchherr, et al., 2017
based on the combination of 3 dimensions: social issues, scale, actors involved.
“A circular economy describes an economic system that is based on business models which replace the ‘end-of-life’ concept with reducing, alternatively reusing, recycling and recovering materials in production/distribution and consumption processes, thus operating at the micro level (products, companies, consumers), meso level (eco-industrial parks) and macro level (city, region, nation and beyond), with the aim to accomplish sustainable development, which implies creating environmental quality, economic prosperity and social equity, to the benefit of current and future generations.”(WEF 2018)

Decentralizing Nairobi As a monocentric city, the fact that a lot of people living outside Nairobi but traveling there daily to work or looking for a job has the pressure on the employment provision in the capital city of Kenya, also it causes the traffic congestion and time inefficiency (Avner and Nakamura 2018). Also, the youth unemployment rate in Kenya is significantly high 18.34% (“Unemployment, Youth Total (Modeled ILO Estimate) - Kenya | Data” n.d.). The circular economy concept applied in the master plan can help allocate the industrial, agricultural zones thus decentralizing Nairobi and maximizing the benefit of the material.

Increased workforce At the same time, recycle process on the one hand reduce the natural resources extraction but need more human resources to collect, classify, and process the used materials on the other hand. Along with the 70% reduction in gas emission, the shift to the Circular Economy is believed to increase the workforce by 4% in each country according to research by 7 European countries (Minson 2016). That is to say, applying circularity in the city scale will provide more local jobs to help deal with unemployment and massive centralization, and develop satellite cities/towns.

02_Self-sufficiency
Vulnerability due to food insecurity People worldwide are dealing with food security, especially in urban areas where people rely on non-local products yet they are not fully aware of the issue. Moreover, in Kenya where there are a lot of informal settlements, daily meals become a big deal. 2020 is a one of the recent years when Kenya has faced the worst food insecurity. Even before the COVID-19 pandemic knocked on its door, the country faced a devastating desert locust invasion coupled with the constraints posed by excessive rainfall experienced from October 2019 (“Why COVID-19 Is Another Blow for Kenya’s Food Security” n.d.).
184
Moreover, Kenya relies on rice and wheat which are estimated 90% and 75% imported respectively. Coronavirus outbreak has led to closed markets and disruptive food delivery (“Why COVID-19 Is Another Blow for Kenya’s Food Security” n.d.). As a consequence, extreme food production deficit and increase price become a blow for Kenya’s food security. Subsistence farms are practiced yet remain fragmented annd insufficient. Therefore, it is of high importance that people start to be aware of that issue and have initiatives to tackle it in microscale. At the same time, the focus on the daily basis has neglected the demand to socialize and improve spiritual life and the need for amelioration of living quality.

Self-operating community project Agro Cite was supposed to be replaced by a car park by the Municipality of Colomes when the funding ended in 2016. The project was successful to connect the “mix of people, from different origins and social backgrounds, exchanging gardening tips”. However, it is essential to acknowlegde the capacity to be self-operating of a community project as well as the communication between governmental and non-govermental actors.

03_Housing affordability
In Kenya, it is very popular that people are long-term tenants or live in informal settlements. It is estimated that 60% of the population live in informal settlements. Coupled with the limited access to land, the housing capacity cannot afford the rising population and the land speculation makes it unaffordable for the citizens. To be specific, the housing deficit in Kenya stood at 2 million (2012) and grows at the rate over 200,000 units per year. Moreover, the living condition is another concern when families live in overcrowded houses typically with one room and lack of ventilation (“Housing Poverty in Kenya: Slums & Vulnerable Communities� n.d.).

Providing sufficient accommodation at a reasonable price by introducing a new ecosystem of sustainable living is an ambitious but feasible solution. Thinking about the recycling of materials, housing units, renewable energy and emphasis on the collective lifestyle is an interpretation of the circularity, which not only helps ease the stress on the natural resources but also the financial pressure on these tenants.

It is also aimed to replace the invest-sell model with the subscription cycle where people can subscribe to their homes (meaning various sectors: plan, structure, utilities, furniture), thus eliminating the need for expensive down payments, while simultaneously turning their subscription into equity stock, that is adjusted to the housing market valuation.

Apparently, this “dream” scenario is too theoretically perfect to be completely realized and able to address all the issues just by one solution. In reality, there are more challenges to reach the stability of the model to make it work smoothly, not only about the huge capital investment but also the uncertainty of the society. However, this is essential to recognize its sense of feasibility and the possibility to be refined and applied in the future.
191
Conclusion
Circular Economy as an umbrella concept for sustainable development Not only in Kenya but also all around the world, Circular Economy has been the strategy supported by both the public and private sectors and applied in various fields for the more sustainable development regarding the overexploitation of natural resources. Although the term is no longer new, it is still a long way to go, especially for developing countries. Considering the context of these countries, it is potential and essential to follow circularity concept now that it has capacity to address not only economic and environmental problems but also social ones. Circularity is definitely not such a perfect answer that could tackle all the issues at once. There are also a number of socio-economic and environmental risks other than its seeable potential benefits (Geissdoerfer et al. 2017). For instance, material circulation is known to produce a degradation of the material quality, requiring additional energy and resource inputs that are often disregarded (Cullen 2017). Or the shared economy is questioned about its deterioration of secure employment despite more job provision (Malhotra and Van Alstyne 2014). However, it is undeniable that the circularity concept is an effective solution to achieve ecological as well as social and economic sustainability. Circular Economy is a complex yet flexible “umbrella� concept that can be interpreted and applied in varied ways, in varied scales. Should circularity become holistic strategy in city development, this complex multi-actor, multi-level, multiphase, and multi-pattern process (Marin and De Meulder 2018) will be a possible direction for the future.

1. UA multifunctional aspects
Urban agriculture: The solution? With urban population growth, food security is a hot topic to address (FAO 2005). In order to solve it, urban agriculture (UA) is reshaping some current urban scenarios around the world (Feifei et al 2009). In that order, multifunctionality has become a key concept towards the effectiveness of agricultural sustainable development (Peng et al 2015). For this research, the UA multifunctionality balance is being critically analyzed between the Social, Ecological, Economical, and Political aspects

Argentina is divided by provinces, giving political autonomy to each of them. Overall, the country has a very complex history, facing many crises during the time, creating a sense of social activism, grassroots initiatives, and collectivism to address the consequences of political decisions (Lattuca 2012). In the case of 2001 crisis, was consequence of the neoliberalism of the epoch (Ferrer 2012). However, even if a crisis comes with high human costs, sometimes a paradise borns from hell (Soler, 2019).

and an example for Nairobi, due to their similar crisis context, and how the sustainable development strategy the study case used, could be evaluated for further implementation in Nairobi’s territory. That strategy was mainly focused on the involvement of the community in the production process, supported by the Municipality to assure land tenure for the orchards, enhancing the territory’s potential and protecting its natural ecosystem. One of the main emergencies Nairobi needs to address is social inequality. Poor and vulnerable people need urban solutions to address hunger, and the support of governmental policies will need to reach that goal, as Rosario’s has portraited.

With extreme population growth and the industrialization of the rural areas triggering land-use changes in the former farming plots, the local municipality of Beijing decided to implement policies to address food security for the population (Cai 2006). The Peri-urban areas were zoned, and since then it could be said that PUA is reshaping Peri-Urban Beijing (Feifei et al 2009). Many Agroparks and Agrotourism projects are being constructed in the surroundings of Beijing since the last 20 years. Agrotourism is the most famous PUA activity and, the multifunctionality of these kinds of projects goes towards the duality between UA and urban development (Yang et al 2016).

Moreover, is important to mention the necessity of these new types of agriculture, occurred due to 3 main factors: The urban sprawl, the rural migrants arriving in the rural areas to work in the industry, and the land competition for different economic activities, as is also currently happening in Nairobi’s peri-urban areas (Cai 2006). Xiaotangshan’s agro park is an example of future larger scaler investments in agricultural technology, and with the case of Beijing of land-use transformations in Nairobi’s peri-urban areas, could potentially attract new investments to enhance not only the food production but also increasing the economy and technology, with the support of the municipality and multiple stakeholders.

Even if the European context is evidently different from Nairobi’s one, however, the similarity is always urban growth, being Brussels one of the most international cities of the world (Corijn 2015). Coping also with the former study case in Beijing, it seems that high tech technologies, aquaponics, and vertical farming are becoming the future of urban agriculture. From this case, what is interesting to evaluate is the circular economy they have created. As Steven Beckers said: “Designing an urban farm that follows positive impact circular economy principles requires the creation of synergies between the farm, the building on which it is located and the farm’s wider urban environment”.

This project is relevant to analyze to see the options that could be supported in Nairobi’s context in the future with a bigger investment. The current context of Nairobi is full of challenges that become opportunities to address those issues in different ways. Circular economies are based in the Cradle to Cradle (C2C) concept. Normally, the objective of sustainable development projects is to reduce the CO2 emissions, but in the C2C buildings, they attempt to create a mechanism to not only reduce Co2 emissions but also to works as a forest does, by implementing physical mechanisms in the building that generate a positive impact in the

The 3 study cases were a success in their context because they managed to collaborate between many stakeholders, creating a multifunctional balance. One of those main actors was to have the support of local authorities and the active participation of local communities, to create urban sustainable development projects and address food security. Moreover, an important conclusion of this research, is that local policies were necessary to implement these projects. Without their support in any of the three study cases, It wouldn’t be achieved. As proof of it, in Rosario the urban agriculture topic was a common interest of some grassroots initiatives before the crisis of 2001 started, however, it only could take place and become a stronger project with the support of the municipality after the crisis occurred. Thanks to the landscape capacity with the initial hard work and knowledge of the vulnerable communities, the project could overlap with that background (Lattuca 2012). Moreover, another positive impact in the communities was the awareness of taking care of the environment through these projects, which is one of the most precious achievements. Learning is a very important process because new knowledge gives the power to the people to take more wise decisions also in the relationship with the environment.

Mi Teleférico is the longest aerial cable car urban transit system in the world. It is serving La Paz-El Alto metropolitan area in Bolivia, a region where 3 million people inhabit (Ministerio de Obras Públicas Servicios y Vivienda 2013). This system was planned to address certain urban issues that are also being dealt with in peri-urban Nairobi: (1) A precarious public transport system based on minibuses that cannot cope with the growing user demand. (2) The high cost in time and money of traveling between La Paz and El Alto, in the case of Bolivia. And, the same situation between Nairobi and Ndenderu, Kikuyu and Ongata Rongai, in Kenya.

and noise pollution. This system connects Las Paz and El Alto, which are completely conurbated. Likewise, they are separated by a steep slope about 400 meters tall and were previously only connected by winding congested roads. In this sense, this study case can be taken as an example for the transportation from Nairobi to Ndenderu, in which its territory, configurated by valleys and steep fertile slopes, is being crossed by roads that are usually congested. This impacts on a negative way in Ndenderu productive landscape and ecological balance.

Following this, the maximum distance between the connected spots in Mi Teleférico is 17 kilometers. In contrast, the center of Nairobi is, on average, 14 kilometers from the centers of Ndenderu, Kikuyu and Ongata Rongai. Thus, considering the similarities between both cases, could a cable car be an option to move through Ndenderu foothills? Mi Teleférico had to face great execution challenges, such as the impact on the landscape in visual terms, the privacy, and the lost jobs of the former minibus divers. Their proposal to cope with this was an extensive participatory process, in order to generate new jobs related to the new transportation system and the creation of an identity of the place.
In summary, Mi Teleférico is relevant for coming up with ideas for Nairobi, as they are both located in a similar peri-urban context, with fuzzy territorial limits and a hilly landscape. Furthermore, Mi Teleférico gives substantial lessons when talking about urban mobility transition in a developing country. This, due to the fact it is the first transport system to use electrical cable car as the backbone of the whole transit network. Therefore, the implementation of electric energy in transportation encourages to overcome from the fossil fuel tendency in mobility, while creating articulated systems.

02_Landscape regeneration through green networks DALANG GREENWAY

ŠJingli 2018
Shenzhen, China
Shenzhen Government
Shenzhen has experienced 30 years of rapid urban development, especially in its central economic district. Meanwhile, its peri-urban areas have experienced a process of rural industrialization, which has resulted in large spontaneous developments of factories and urban villages (Qu, Fu, and Calabrese 2015). Dalang is one of these peri-urban enclaves. It is located right on the border of the CBD (central business district). It has been transformed from a green-rural field into an industrial area dominated by manufacturing industries. In recent years, the government of Shenzhen has envisioned a multiscale project, which would articulate the region, the city, and the neighborhoods through greenways.
214
This was proposed with the goal of regenerating ecosystems and recovering the human scale and the contact with nature. The program of greenways has been a success in China. In this context, the big difference from the study case and Nairobi may be the budget, the politic willing and the institutional capacity. Nevertheless, it is possible to think that nature recovers what belongs to it. The flows of the rivers, the wetlands and the footprints of the forests, framed by the topography, define the territory and allow the greenways to emerge in peri-urban contexts.

Main components of an integrated greenway system in Dalang

For instance, if a greenway system would be created in Kikuyu, it could help to mitigate the loss of ‘natural’ space that has been happening in urbanization projects that had come over the swamp, fragmenting the forest system. It also could provide scenic qualities in the landscape, as well as recreational functions while preserving the natural ecosystem. Such multipurpose greenways usually involve every territorial scale and planning levels (Fábos 2004). Therefore, a green network could frame the mobility between the Kiambu County, Kikuyu and Nairobi. Therefore, a greenway system in Kikuyu could work as an ecological framework, which varies greatly in scale, from small green streets that run through urban, peri-urban, and rural areas, to wider corridors that incorporate diverse natural, cultural, and landscape features. By connecting fragmented forests ecosystems, a greenway can facilitate the movement of the people of Kikuyu in and around the town framed by the forest system. It may integrate diverse urban functions, while providing aesthetic experiences. Furthermore, greenway system linking suitable patches of habitat is a promising strategy to maintain biodiversity, and fostering slow mobilities, such as walking and biking (Ahern 1995), and even animal crossing.
Planning proposals of an integrated greenway system in Dalang
The Dalang greenway, by connecting existing green routes and slow-traffic routes, give lessons that could be applied in peri-urban Nairobi, such as enhancing the accessibility to the greenway network by public transportation, allocating transit nodes along the existing public transportation routes. Also, it can be a reference case on making use of vacant spaces in both the urban context and the productive areas to create a public space network, by adding vegetation and diverse urban functions to such places, and connecting these scattered spaces in the compact urban areas. And finally, it can also be used as learning experience on developing secondary road networks within neighborhoods as

03_Infrastructure conversion into slow-mobilities networks OTAGO CENTRAL RAIL TRAIL
2000

South Island, New Zeland
Otago Central Rail Trail Trust
The Otago Central Rail Trail is a 152 km walking, cycling and horse riding track all off-road, that was built over a rail trail. The original railway line worked form the 1930’s to the 1980’s transporting old, due to it was a pastoral-farming and mine area (Ministry of Tourism 2009). In the early 1990’s, the segment between the towns Clyde and Middlemarch stopped working as a railway. At that moment, the New Zealand Department of conservation recognized its potential as a connecting facility, as this infrastructure bordered several small towns and agriculture fields areas that, by that moment, were reachable jut by car.
216
This study case can be taken as a model for using remaining infrastructures into slow-mobility systems to move through agropastoral landscapes. That could be the case of Ongata Rongai at the south of peri-urban Nairobi. Which has an excess of vehicle infrastructure that is pulling out the cattle, and putting the animals in risk as consequence of their presence over the roads. Therefore, as in Otago Central Rail Trail, which always has had the goal of maintaining the agricultural nature of the landscape, Ongata Rongai has the chance and the challenge to rethink the way their inhabitants and their main resource -the animals- move across the territory.
Š Otago Central Rail Trail Trust 2017
The Otago Central Rail Trail Trust, the community organization that join forces to recover the rail trail and use it as a slow-mobility path, organizes workshops with the villages and farmers to manage the balance between the new slow-mobility infrastructure, the tourism that this infrastructure attracts, and agriculture. Thus, in the case of Ongata Rongai, it could be possible to take advantage, for instance, of the residual spaces left beneath the new train infrastructure, allowing the flows of both animals and people across it at the ground level.
In addition, as it was demonstrated in the Otago case, reforming the lanes and giving space to the landscape to be enjoyed can be a boost for tourism and economic practices. Infrastructural systems work like artificial ecologies, controlling and regulating movements (Otago Central Rail Trail Trust 2017). Hence, the practice of re-using infrastructure can frame the grazing productive landscape in Ongata Rongai. In sum, the greatest lesson of the Otago Central Rail Trail for Nairobi is the capacity of the community effort on taking advantage of old and underused infrastructure in order to transform it into new lanes.

action. The three study cases of this paper resulted from the coordination and synergy of governments and citizens that sought to inhabit while moving through peri-urban contexts. As Samir Bantal observed, “the countryside, a place many of us think of as stable and slow-moving is revealed as an incredibly agile and flexible realm, even more than any modern metropolis� (OMA 2020. pp. 1). Hence, envisioning new forms of moving through the peri-urban Nairobi productive landscape is needed. For this, joining fragmented natural ecosystems and taking advantage of the underused infrastructures is a starting point. In an interview in 1982, Foucault stated that the three great variables of the spacetime are the territory, the communication, and speed (Allen 1999. pp. 4). This makes me question: In order to make a change in how we move, must we also change how we communicate and how we inhabit the territory? The most probable answer is yes, because the traditional forms of mobility have been shaped in a highly

GXN + 3XN Architects, BCVA
Aarhus, Denmark
The first case study is the AGRO Food Park Extension in Aarhus, Denmark designed by William McDonough + Partners and GXN together with 3XN Architects, BCVA and Urland. It is the future of food and plant resources and is an innovative way to fuse agricultural practices with urbanity. The five focus areas of the Agro food Park Extension is healthy materials, clean energy, increased biodiversity, healthy air and clean water. It is a carbon positive city demonstration where physical elements, energies and resources flow in a loop of economic and ecological innovation and regeneration.
221
The lawn in the heart of AFP is a place for agricultural innovation and testing different production methods of crop cultivation. It is a combination of kitchen garden, beehives, energy crops, orchard and meadows. It is the communal place where people walk around to take a look at these various agricultural innovations.
223
Energy and resources remain within the system of this food park as they flow through different infrastructures. The biowaste and manures are reused for energy and irrigation while the excess heat from the infrastructure is used for the greenhouse production. Amenities like office space, gym, lounge and collaboration space surrounds the lawn with their shorter faรงade facing the street giving the feeling of connectivity in an urban context.

02_Self Sustaining Village REGEN VILLAGE
EFFEKT Architects
“ReGen Village�- a regenerative and innovative housing model is designed by EEFEKT Architects which acts as a solution for social, environmental and economic issues currently faced globally. t is a self-sustaining neighborhood design that can be placed in any place over the globe. It is a self-sustaining neighborhood design that can be placed in any place over the globe. Agriculture is one of the biggest reasons behind environmental degradation and loss of biodiversity which is why this housing model comes up with a sustainable agricultural model.
225
The design of this village model involves different forms of applied technology like energy positive homes, renewable energy, energy storage, door-step highyield organic food production, vertical farming, aquaponic, aeroponics, water management and waste to resource systems. The model also reduces the space occupied by human being by bringing in office and communal spaces closer to the dwellings. This will open up a new form of peri-urbanism and rural development that is sustainable for the environment and provides convenience to human life.
226
The dwelling infrastructures are placed around the communal and production spaces. 8 squares are connected with the housings and they are used for dropoffs and charging station for cars. Social spaces are created between the spaces of every built form to ensure a complete integration between food production and housing units.

03_Permaculture ZAYTUNA FARM Australia
Zaytuna Farm is an family friendly farm of 67 acres which is an extensive permaculture demonstration site that fronts Terania Creek opposite of the village of The Channon in Australia. The property contains 800meters of Creek frontage, numerous swimming holes and abundant wildlife. The landscape contains varied elements like high frost-free hill tops, ridges and valleys with both cleared paddocks and forest areas.
229
It is an ever-evolving ground research in practice where students can learn about different sustainable productive systems and real-life permaculture techniques and farming. Different farm systems that include animals, crops, trees, nursery, aquatics, irrigation, renewable energy, waste and recycling are other practices are incorporated with it. Other tasks include making compost and natural fertilizers from the leftovers of the farm. Pesticide-free farming and producing no waste is the key to permaculture farming. An integrated water harvesting system of multiple dams, ponds and swales with gravity irrigation is also designed throughout the site.
230
The infrastructures of this farm are made up of straw, bamboo and stylish upcycled shipping containers with passive solar aspect winder vented metal roofs. The electricity in the farm is generated by standalone off grid solar with generator back up, all toilets are state of the art composting toilets, all grey waste systems are gravel reed bed natural biological cleaning system all approved by the local government.
231
Conclusions Nairobi peri-urban areas suffer the consequences of land fragmentation and ill agricultural practices with environmental degradation. Land is a finite source and promoting multiple usage of a piece of land is very crucial to see any development. The Agro food park extension project shows how a small piece of land can be used fusing urbanity and agriculture to increase productivity and chances for innovation and entrepreneurship. The self-sustaining village model is a wonderful example of sustainable neighborhood design that uses resources and limit the area of impact that human being intervenes with their activities on a regular basis. The model shows how to inhabit in physical environment while allowing it to survive and not compromising human beings benefitting from it. Agricultural practices in peri-urban areas of Nairobi is threatening natural systems and wildlife. Zaytuna farm exhibits the practice of permaculture and how it can be applied in the reality that combines sustainable farming and construction methods. It involves a deeper understanding of how can the natural systems work in synergy with human activities and learn about pesticide-free farming.

Their relief and type of soil based on plateaus, make them proper for agricultural activities (Bautista and Palacio 2012), and they even function as mammalian corridors (figure 3a) (Varela and Trabanino 2016). That situations are part of Nairobi’s landscape, where we can appreciate potential areas in which the agroecological system could be applied (figure 3 b, c, d).

The second part, from 5 to 10 years, is for planting fruit trees such as plantain, banana, and papaya among the existing maize fields. Also, small trees like mango and avocado are part of the process (figure 4c).

A third phase could take from 10 to 15 years; mature trees serve as a canopy for small plantations, inhibiting undergrowth. In the fourth cycle, the forest transformed into a hardwood forest without underwood (figure 4d). The period starts again with plants typically cultivated from seeds saved (Watson 2019).

The productive landscape for the Nairobi valley system The Chagga culture lives in the Kilimanjaro mount. Its plantations develop between 800 and 2,300 mm, which means that its fields are mostly sloped and, at the same time, quite productive (Hawksworth and Bull 2006). In the Nairobi landscape, the slopes are quite predominant and repetitive in the complex river system of the city. Also, due to their similarities in location and altitude, the plantations species are similar as well. Four vegetation levels of plantations across the sloping terrain allow the development of this mixed activity between forests and crops. The highest level

A third level made up of plantation bushes such as coffee or beans and, finally, vegetable crops at the lowest level (Dagar 2018). In figure 5, it is possible to appreciate the distribution of the plantations of Chagga people (Hemp 2005), but for the research it is adapted to the local species of Nairobi (Bernard 2001).

Reinforcing the forest An ambitious vision and to intensify green areas made up of forests, thinking about environmental and social sustainability. Nairobi’s complex topography allows both indigenous techniques to be applied to its plateaus and valleys in search of reinforcing forests while achieving productivity to promote the agricultural activities that usually carried out. Both Mayan and Chagga cultures have demonstrated for centuries that it is possible to carry out these sustainable techniques which could apply in the areas shown in figure 6.
240
It is even possible to carry out an organized structure of the plantations, in contrast to the random distribution of indigenous cultures, to guarantee a correct delivery and production that optimizes the possible harvesting of crops.

Greening Productivity A technique practiced around the world to combat climate change, promote forest growth, increase land productivity by allowing livestock combined with reforestation, is silvopastoralism (Dagar 2018). The southern part of Nairobi in municipalities such as Ongata Rongai is characterized by its high livestock activity on mostly flatlands, being this one of its main economic activities. However, the livestock activity goes from being formal and industrial, to mixing in the urban landscape informally and without meeting safety standards (Figure 7).
Occasionally, due to the dry seasons, livestock must be moved to areas further north due to food shortages. However, to the north of Ethiopia, a neighboring country, an indigenous technique by the Tigrayan community seems to offer a solution.

It can see how southeast of Nairobi, in the town of Ongata Rongai, wide-open fields are part of the livestock landscape, a potential area for silvopastoral and increase the number of livestock forests (Figure 8a, yellow texture). A substantial change will occur in the area if we compare the hypothetical case proposed in figure 8b. With the use of indigenous tree species, that, in turn, allow livestock to be fed as an alternative when the grass begins to scarce.

However, indigenous cultures have been characterized by their practice and evident success, without the need for the machinery and infrastructure that civilized societies imply. The techniques proposed in this research are very similar to the Kenyan situation due to different characteristics such as geolocation and altitude. The location in the tropical region of these cultures and their temperatures may also be the reason why agricultural products are so similar to the Kenyan consumptive culture. Reasons that make these techniques become considered viable for applying in these soils, both in valleys and also savannas. Even planning engineering projects that take advantage of topographic complexity, could generate potential areas for new water reserves and thus have new artificial reserves that can optimize agricultural processes.

the plateau, as well as the relationship between these respective natural systems. Disperse settlements also lowers access to economic and social opportunities as well as the potential for upward social mobility. The housing production of the regular market is monotonous and targets, in general, nuclear families. As such, housing production is not adapted to demographically defined changing of societal needs and economic possibilities. Examining the cases to follow is an attempt to understand and find new productive ways of human cohabitation with the natural environment and with each other. The cases thematically explore collective living defined as: ‘Communal living: with the land and with others’; through this case I attempt to understand a set of relations of the residents with each other and with the land. ‘Infill living: together on the street’; the street is a space for mobility, trade and social exchange. Building the urban wall capitalizes on the existing opportunity the street provides. In addition to this, illustrated here is the need for secondary public realms for other kinds of interaction, and where new communities can form. ‘Cluster living: communally settling the landscape’; leveraging on local building tradition as a means to capacitate and empower local tradesman.

Vandkunsten Architects 1982-1984
Brief overview: Completed in 1984, this project can be seen as an exemplary case that demonstrates a tradeoff of individual private space for communal space. The building encloses an exterior productive landscape where communal responsibilities are shared. The private domicile are double banked to form a public interior street-like place. Comunal areas, such as kitchen, living areas, laundry rooms, workshop spaces, as well as music rooms are within this space and at the corner of the public interior. The spatial organisation here facilitates productive communal relations; however, not all residents have thrived here. With this model, high levels of participation and volentary work is demanded. This project begins to ask the folowing quesion: how can we begin to find new ways to prioritise the collective over the individual? Building collectivity: Pictured, the housing development is appropriately scaled to relate to the human scale and the contour of the landscape. The building reads and separate homes joined by a shared space. The glazed interior ‘street’ provides spaces to socialise and for children to play in all year round.

Separating elements: Evident in these drawings is a careful use of material, form and shadow to allow elements of the building to be perceived as separate elements to create an image of village as opposed to a monolith.

Brief overview: La Borda housing co-operative is organised by its residents to provide decent, non-speculative housing. This is formed through the implementation of a collective organizational structure. The project has 28 units varying between 40, 60 and 75 square meters. Communally shared facilities include; kitchen-dining room, laundry, multi-purpose space, health and care spaces, external and semi-exterior spaces. Community & Variety: Living units are organised around a large enclosed courtyard. Smaller units are placed on the south-facing facade to maximise its potential. Mixing a variety of unit sizes and types diversifies the socail make up of the community as opposed to modernist mulitiplication models based on the idea of the nuclear family.
Participation & Capacitation:
Š Google Earth
Involving the future / potential inhabitance of the project in very early stages was seen as key principle in developing the brief. As the project developed, so did the participants. The use of cross laminated timber construction was part of a strategy to fast track instruction and minimise wet trades to maximise the involvement of the community in the buildings production.
253
254
Personalisation & adaptability: Units are designed in a way to allow for relatively easy reconfiguration. This is done by a rationalizing of services, and shear walls as fixed components while internal walls, doors and windows are the same proportion. Activation & public hierarchy: The street facade of the building is activated with ground floor communal activity spaces and lettable commercial space. The interior courtyard, roof patio and multi-purpose space, provide a hierarchy and gradation of public spaces. The spaces provide opportunity for varying social groups and communities.

Conclusions The indicators and objectives for good housing and Responsive Environments (Bentley, 2015) have been extensively written about by Habraken, Turner and others; the cases studies here demonstrate ways of collective living. Co-housing and collective housing are much more than shared communal facilities. It is based on a set of complex social relations that have to be built through iterative social engagements. Expressed through Simone’s (2004) notion of ‘People as infrastructure’ where he speaks of the city as a space of complex social- spatial productive relations. A return to the notion of the public (urban) commons (Latour, 2017) is critical in creating a hierarchy of social equalizers. The importance of the streetscape in the global south is one such space; however a greater variety is required. The cases here show, enclosures / creation of these public space as sub-sets. These spaces are where communities and social bonds are created. Reflecting on this work in relation to the peri-urban life in west Nairobi, the first question is one of order. How can spatial practitioners create new orders that work with existing systems to create new relationalities for new potentials to emerge? The second question is one of efficiency. In such contexts where public infrastructure investments have to work hard, how can maximum value be extracted from limited means, how can a sense of ‘ownership’ and responsibility be transferred to the users? Thirdly, adaptability and valency. In a place that is rapidly changing, and uncertainty is constant how are environments able to adapt, and respond and attract new uses and programs?

3_Beyond the Forest: Seeding the Future of West Nairobi Benjamin Baggot, Santiago Cortinez, Zeeshan Ghani, Khanh Nguyen, Silvia Parra, Natalia Recalde
Despite being a relatively new city, Nairobi has been Kenya’s main urban centre since the early 20th century. The city has attracted many people across the country due to its vibrant culture, economic opportunities, lifestyle and landscape, all of whom have added its dynamic urban environment and rapid urban growth. In order to sustain this development, considerable
resources
are
being
consumed. Which leads us to ask: What feeds Nairobi? and where are these resources coming from?
The peri-urban areas of West Nairobi are not just an extension of the capital city, but rather a mosaic of landscapes that provides Nairobi with many of the valuable resources the city consumes. Here, the landscape rapidly changes from savannah to forest. This change is highlighted by three main ecological systems: the savanna, the Kikuyu water tower and the valley system of Ndenderu. These three areas are all interwoven with the city. A large portion of Nairobi’s water is provided by the valley and wetland system of the Northwesten watershed, whilst food is being produced in the grasslands of the southwest and the agriculture rich areas of Ndenderu.
28
With a growing population and a desperate need for housing, large portions of West Nairobi are being eaten by a sprawling metropolis that pays little to no attention to the landscape it is embedded in and the natural resources it consumes, destroying a valuable landscape to the detriment of the city.
The
fragmented
urbanisation
is
consuming areas of high food production and ecological importance. As a result, Nairobi is at risk of losing its rich agricultural and ecological history as well as its main water resources. Increased
levels
of
deforestation,
minimal waste management, pesticides and overconsumption of water have all put Nairobi’s water security under heavy pressure. What if the territory holds the key for the solutions?
29
Historical documentation has unfolded a landscape with multiple complexities and intricacies, revealing the loss of large forest and water ecosystems. These natural systems can build the framework for the reviving and upgrading of West Nairobi. By using the territory’s potential, we take advantage of the natural elements already there, which is especially important in a place of scarce monetary resources.
Valuable portions of preserved landscape still exist. Nairobi National Park, the Ngong Hills and multiple forest reserves are highly biodiverse environments. Within this forest and savanna mosaic there is also an existing forest plantation system. The knowledge of where the historical forest was, provides a framework that supports the design of a healthy and productive urban landscape.
30
The reclamation of forest and pastureland will support an improved water management system and preserve resources while providing much needed public green space. Within the historical forest framework, existing agricultural landscapes are transformed to become productive forests through agroforestry practices. New urban environments are implemented, that comprise and combine the qualities of environmental protection, production, public space provision and improved accessibility.
31
Interventions such as grazing parks provide spaces for both animals and people. Open grasslands, sports fields and playgrounds can be used as public spaces to socialise with the community while sharing the area with animals. Pockets of forests compliment the grazing park system, working as water management infrastructure and also providing an ideal environment for social amenities. The parks connect the suburban areas and urban islands to the surrounding agricultural structure.
Creating publicly accessible paths that follow the lay of the land will help include forests and agricultural fringes into the public sphere, while also delivering substantial health benefits. To create ease of movement, the forested paths follow contour lines. The level landscape and the increased density of trees will help retain rainwater, allowing the run-off water to seep into the soil, reducing the farmers reliance on irrigation.
Community involvement is essential for planting and managing the forest reclamation projects throughout the territory. By actively involving the citizens through stewardship schemes, reforesting the landscape becomes a viable project. One example of this, is to encourage greenhouses

programme around their infrastructure, in order to mitigate their negative impact on the land.

Existing landscape The ridges support both urbanization and agriculture. A distinctive urban tissue recalls the shape of the traditional rural town of Ndenderu. The continuity of the wetland ecosystem along the valleys is disrupted by road infrastructure. Remaining patches of riparian forest resist urbanization encroachment.
Ecological intervention Reclaimation of riparian forests as well as different types of productive reforestation are used to create landscape figures that delimitate urban growth. Ecological balance is restored transforming the roads into bridges to allow continuity of the wetland ecosystem.
66
Community involvement Local people are involved in the reforestation program with the creation of Community Forest Associations, cooperative farms and the invovement of educational institutions. Tree nurseries, plantation, irrigation and agroforestry practices are part of the activities taken care by residents.
Types of forest implemented From left to right (1) Existing forest: remaining patches of indigenous forest (2) Agro-forestry: combination of agriculture and tree plantation (3) Productive forest: sustainable production of timber (4) Water management forest: strategically located pockets of forest and vegetation for water catchment and cleaning.

The uncontrolled urbanization has gradually eliminated the pastoral lands which is considered the identity of the Southwest of Nairobi, particularly Ongata Rongai. Also, ecouraging livestocks and devloping livestocks trade can help Ongata Rongai depends less on Nairobi. This project is to introduce a co-existence between humans and livestocks which, on the one hand, affords housing demands and increases living condition, and integrates pastural grounds in urban fabric on the other hand. By doing so, it is expected to encourage small-scale livestock herds and new concept of urban pasture. Urban islands, Suburban and grazing parks or ecological corridor seem to be seperate zones with different functions. Yet they are well connected by the movements of animals (at different levels) and the network of forestry extended to the very urban areas. Co-existence here is about not only integration but also the increased benefits.

Master Plan of Individual Site (Ndenderu Junction) The site is a square with 1200m edge situated close to the Ndenderu Junction. The main site force is the river-valley system and the rich potential agriculture lands. The corridor extentions and new private and shared gardens and farmlands create a system of continued landscape corridor in this site.

Past
Present
Proposal
Section The topograpgy of ndenderu is mostly dominated by the ridges and valleys. In previous times, rivers used run through the valleys but with rise of unplanned urbanism, they got erased mostly. The settlement growth ate up forest and agriculture lands as well. The proposal tries to bring them back and connect them to the urban system in a more efficient way .
49
Corridor extension The dispersed patches are connected to make a continuous corridor.
New forestry The volume of the forests are increased and pockets continues inside settlements
New Urbanism Clustaring houses gives more accommodation with accessibility and open spaces.
Water Extentions Rivers are reconnected. Retention ponds are introduced for rainwater harvesting.
50
Courtyards Common courtyards are introdced to increase social sharing and accessibility.
Backyard Farming Backyards are transformed into flower and vegetable gardens for productivity.
Communal Farming Shared gardens, orchards and farmlands for comunity agriculture.
Agroforestry New productive forests are added with the core forest for enhanced productivity.
51
Reconnecting Corridor Dispersed patches of forests are exended to make a continuous volume of urban forestry. Orchards are placed with the corridor to increase productivity. Also the dried up rivers are dug and made wider and in the edge are transformed into deeper ponds to create water park and aquacuture ponds. Eventually these water parks can be transformed into entertainment places for the community. During dry season, when the rivers are almost dried up, the silt they leave can be a very fertile plant bed. These are potential for different crops that can increase the overall productivity of the area.
52
New Tissue Following old Morphology The new urbanism intertwines with the regenerated landscape mosaic consisting of patches and corridors. These are also connected with smaller patches of courtyards, private forest, communal gardens, backyard farming or traditional farm lands. The existing urban morphology is not dislocated here, just the concept of blind following of urban growth only being dominated by roads and infrastructures are changed. In the new prposal, landscape features as water, forest or farmlands are the driving force of settlement growth. Few old buildings with temporary building materials are defined as relocable structures and replaced with new buildings in different strategic locations so that the overall flow of spaces are enhanced. These intentional interwoving relation of urbanization and forestry accompanied by productive landscape reinforces the concept of “Rural Metropolis�.

Kikuyu: Revamping rural-urban transitions The landscape in Kikuyu is defined by two plateaus separated by a soft valley system of forests, marshland, and rivers. The urban core is set on the eastern plateau whereas rural farmlands form a matrix on the western plateau.
The main water features are the Ondiri swamp and Kikuyu springs which are recharged by the Kikuyu aquifer. They are sources of major rivers that serve Nairobi City downstream.
Deforestation and degradation of the swamp and the riparian zones prior to uncontrolled urbanization are evident. The development of industries and greenhouses close to the swamp has escalated the water pollution and subsequent water scarcity in the region.

Proposal: New Ecological Systems and Water Sensitive approaches New forests, parks, rain gardens and boulevards will help in stitching the fragmented forest patches, be potential zones for productive agriculture, storm water management and recreation.
73
Kikuyu Waterscape Ondiri swamp and Kikuyu springs locally provide water for domestic use, farming and to the industrial sector.They are currently threatened by pollution and over-extraction of water from the farms and the industries.
74
Strategy The design pursues new agricultural techniques, scalable water management, new water reserves and natural waste-water treatment ; towards water sensitive design and sustainable agriculture in the rural and urban zones of
Water-Sensitive adaptations in the Kikuyu Urban Countryside Integrate sustainable storm-water management using rain gardens and swales; groundwater recharge using infiltration basins and permeable paving; natural wastewater treatment by use of constructed wetlands and scalable water management from the household to neighborhood scale through coordinated water supply, rainwater harvesting and drip irrigation in the farmlands and gardens.
75
Reforestation Dense forest areas have been fragmented overtime. The bare spaces left can be transformed into ecosystem corridors as well as productive landscapes. New forests will create new wildlife habitats and help in carbon sequestration to curb climate change.
76
New Productive Agriculture Intercropping, water management systems and cleaning ponds can take advantage of the fertility of the soil while keeping the water sources of Kikuyu clean. Communal orchards can utilize drip irrigation systems to manage water use.
New Water Systems: Rainwater Harvesting // Community Reservior // Water Pans New water ponds and use of drip irrigation systems will help to improve rural farming and new orchards in the urban areas. Rainwater harvesting and use of communal reservoirs will help to conserve water by minimizing digging of many private boreholes. An industrial park as a transitional zone between the river and the industries can incorporate constructed wetlands to polish industrial effluents before discharge.
77
New Ecological Corridors New water systems need to be anchored within new forests. Reforestation can take place by connecting the fragmented forest patches creating a new ecological corridor that connects water and forest systems. Boulevards along the streets, reforestation of the bare patches as well as new woodlots along property lines will form the new forest systems. New communal orchards, parks and forests will collectively form the new ecological corridors that will transorm the outlook of natural resources in the territory.
78
New Urbanization To meet the rising demand for housing in this fast growing town, this design pursues affordable infill housing and self-build linear cohousing along the ridges. To minimize pollution by the greenhouses and industries, an incremental change of the greenhouses and warehouses is proposed to maximise capacity yet ensure maximum distance between the water sources and the structures. A proposed industrial park next to Magana industries as well as 3 other constructed wetlands on the fringe of Ondiri swamp will ensure natural waste water treatment before discharge.

Section: Past, Present and Future conditions Before rapid urbanization, forest systems were denser, the water sources were cleaner, the watertable was high and there were few settlements. Today, patches of bare land, groundwater over-extraction that lowered the watertable level and rapid and less controlled urbanization characterize the Kikuyu region. The proposed eco-corridors will ensure creation of new habitats, productive agriculture and scalable water management and this will reclaim Kikuyu’s water and forest ecosystems. A new codependent system of urbanization shall meet the urgent housing needs and ensure nature-sensitive development.

The current status of the selected site is characterized by fast urban growth, in an expansive way, where housing is mostly one or two stories tall, although new typologies such as midrise buildings of four to six stories tall have been introduced. The challenges that this site faces are the uncontrolled urban expansion that takes with it agriculture fields, the need for more housing, and the absence of public space.
104
The starting point of this project is public space, a public space system will be introduced, converting existing roads into green walkways, constructing new walkways through large blocks and creating new public spaces through land pooling. A new park that will serve both the Maasai husbandry, people, and nature will be introduced in what is today mostly private-owned bare land.
105
106
Some housing will be transformed into new vertical one that will allocate existing and new residents. The space gained from this construction will be transformed into agriculture, new facilities or public spaces. This process is going to be gradual, incentivized and its not pretended to take all over the site.

Inhabiting the Forest Plateaus
Our strategy, Inhabiting the Forest Plateaus is to embed urban development within the natural landscape.
28
Territorial Vision
Our analysis recognizes that resourceful productive areas are located in the downstream valleys of these plateaus, and topography acts as the spatial organizer of West Nairobi. Our vision is to align territorial function with the suitability of the land and locational assets. We propose to use afforestation to enhance the natural characteristics of the landscape and create a robust ecological structure that invites sustainable urban development.
29
Framing Forest
While the framing forest strengthens the ecological structure, hinders erosion and positively impacts micro-climate and water resources, it simultaneously frames urban development. The upstream densified housing and new facilities generate urban pressure on the plateaus. It organizes a spatial alteration between raised densification on the plateaus and fertile downstream valleys.
30
Productive Forest
The productive forests strengthens the productive agro-urbanity in the making of West Nairobi. It increases biodiversity and reduces the ecological impact of traditional production activities, while taking advantage of the existing natural resources and features of the land. The productive forest absorbs urban development, creating a new way of living embedded within productivity.
33
Water Catchment Forest
While the water catchment forest is a vital element for the downstream productive landscape, it also mitigates potential climate change impacts and is important for the upstream settlements. The inhabitants of West Nairobi develop an interaction with the natural water sources and the sharing water becomes part of the new ecological way of life.
36
At the north plateau of Ongata Rongai, the existing quarry presents tremendous opportunity. Having been exploited for over 50 years, the quarry is now in the final stages of its productive life.
Foresting this area recovers soil for planting nappier grass, a primary food source for livestock. A wetland system is introduced, reutilizing the alreadyexisting terrain. This system serves as a reservoir of water during the wet season and as silvo-pastoral grass during the dry season.
37
Forest Ways
Forest ways are green slow paths that aim to shift towards a socio-enviro mobility network in West Nairobi. Forest ways provide ecologic and economic connections across the sites, establishing a social relation between the various natural and human elements in the landscape.
38
Around the forest way, a border of silvopastoral production is proposed, which is protected by a framing forest in which the productive communities live. Considering future growth, the new urbanization is planned on the plateau. It is articulated with the productive communities through a linear local market.

The specific site deal with creating a sustainable solution of Permaculture farming embedded with high density settlements along with forest armatures to reduce encroachment. Food production is a crucial element of this site and it is necessary to bring a balance between ecology and economy.

The introduced settlements along the forest armatures aid in the system by contributing their waste water that nourishes the plants, passes through bio-swales where the movement of water is slowed and filtered through different reed systems as it passes down the slope. Every cluster of houses has a retention pond to ensure that there is always a natural water resource and all the purified water passes the final purification wetland before it flows down the swamp.
67
Existing agricultural practices are replaced with permaculture and blend of agroforestry. It is a production system that benefits the restoration of natural systems and also human consumption and economy. Fair share is related to limiting consumption and putting surplus back into production system. Permaculture zones of use are at once an organizing force during the design process as well as a management tool. They directly aid our efforts by offering simple, but effective logic to the positioning of design elements in the whole system. The closer an element is to nexus of human activity, the more attention it can receive than elements positioned further away. This is because the amount of time and energy embedded in travel always increases with distance.
68
Wetlands has a natural capacity as filters. Because they are found down low in watersheds and they are used to filtering everything coming down. Artificial wetlands are built to handle wastewater and use the biology of healthy soil and aquatic plants to break the bonds and absorb pollutants. Using permaculture design replenish and clean water and and restore a healthy hydrological cycle. Wetland park is created around the swamp to celebrate its natural system and also create a source of recreation of the dwellers in Kikuyu.

Our vision is to capitalize on the transformative potential of this in-between moment in the urban life of Kikuyu by re-imagining these infrastructures to incentivize the densification of settlement on the plateau by restricting its boundaries, whilst simultaneously de-densify the lowlands. The edge of the plateau is intended to be enclosed through re-forestation with different but complementary social and ecological functions, particularized through their relation to each adjacent urbanity. The re-forestation contributes toward the reinforcement of the larger system spanning the western edge of Nairobi. Armatures commonly associated with settlement along a route; is particularized and programmed as ‘forest-armatures’ that bridge the urbanized plateau with local green systems, whilst conversely in the lowlands, translate as sparsely urbanized connections incorporating new kinds of agriculture and other economically productive activities between plateaus. The idea of ‘forest-armatures’ is conceived of as an urban tactic capable of being deployed at varying scales and through diverse programmatic activities, whilst consistently constituting both settlement and natural systems along a connecting route.
In Kikuyu, one of the strategies we employ is the notion of ‘forest-armatures’. forest-armatures is conceived of as an urban tactic capable of being deployed across the terrain at varying scales and through diverse programmatic activities, whilst consistently constituting both settlement and natural systems along a connecting route. The Forest Armatures bridge the urbanized plateau with local green systems, whilst conversely in the lowlands, translate as sparsely urbanized connections incorporating new kinds of agriculture and other economically productive activities between plateaus.

2X2 Stratergy
In Kikuyu the plateau known to locals as ‘the water tower’ is divided from the valleys below by infrastructures, such as the railway and the Southern Bypass that connect West Nairobi. The countering logics of the railway which follows the contour, and that of the bypass which cuts the landscape, is used to create a framing forest that mediate these rationalities with that of the landscape. The framing forest enclose the edge of the plateau with indigenous reforestation. The reforestation contributes toward the reinforcement of the larger system spanning the western edge of Nairobi. The vision for the site is both to reinforce the existing and create new relationalities between the pre-existent and the proposed settlements, and the ecologies of the area; to mediate an interrelationship between the human and natural habitats of the plateau, with those of the valley. On the plateau and its foothills, this is envisioned as a series of discrete yet connected social infrastructure interventions. This is to be achieved through the balanced insertion of additional social facilities and functions, creating new and respecting the existing ecological logics of settlement. These insertions aim to organize and catalyse appropriate development on the plateau while simultaneously incentivizing de-densifying the valleys below, to create community scaled public spaces. The nature of the insertions and its spatial and programmatic specificity is conceived of so as to afford the possibility of evolving a non-linear program of implementation, so as to respect established local cultural practices.

Warer Places Water flowing from the highlands in the north of kikuyu is captured and retained on the plateau in a series of pools, each supporting a pocket of forestry and wetland ecology that contribute to the cleaning of the water resource as it flows. Coupled with new and existing social infrastructures, these ‘Water Places’ become sites with social valency and a critical resource for agrourban activities. The resultant systems are intended to create and encourage gradations of nature through their complementary levels of enclosure and publicness. Water can be used as a primary sponsoring tool to achieve this; building upon established community social practices and community processes. These will contribute directly in managing the sharing of common resource; by inserting new resources, collective places and infrastructures that enhance those that already exist.

Ongata Rongai has a unique landscape as the area is still predominantly pastoral. To preserve this identity, address land conflict between human and wildlife, and combat climate change impacts, the following interventions were introduced: rehabilitation of existing grazing lands by integrating communal indegenous enclosures, integrating agroforestry and agripastures as coexistence borders, adding wetlands and waste stabilization ponds to re-use storm and waste water, protecting area reserved for greenhouse forest and opening up urban cores for urban agriculture.
88
To harnessed productivity of areas near Kandisi and Mbaghati rivers, urban agricultural pockes, agripastoral areas, forest catchment and animal corridor were integrated into the landscape.
The new dwellings were clustered to allow animal movement around individual and communal agripastures.
Waste stabilization ponds were introduced adjacent to the urban core to maximize urban household’s waste water discharge that are treated to serve as water for agipastoral irrigation.
89
The forestways for livestock crossing at the river allows the animals torest and enables the rotation of grazing lots.

5x5 propsal for Ongata Rongai
As animal’s movement is limited by the current urbanization and roads, a forest way that allows animal to travel between the two riparian areas is established. In the new productive borders along the river small paths that allow animals to cross the rivers are added. These strategies aim to protect the socioeconomic practices of the Massai community.

Floodable areas
Dwellings relocation due to flood risk
During the wet season, flooding areas in the south of the river where animals have access to water are designated as protected pasture lands. Also, a forest way is proposed for the circulation of livestock between the plateau and areas at the south of the river.
Silvo-pastoral border
Silvo-pastoral edge
Around the forest way, a border of silvopastoral production is proposed, which is protected by a framing forest in which the productive communities live.

New productive communities on the framing forest
Considering future growth, the new urbanization is planned on the plateau. It is articulated with the productive communities through a linear local market.

Proposed conversion of the Kandisi quarry At the north plateau of Ongata Rongai, the existing quarry presents tremendous opportunity. Having been exploited for over 50 years, the quarry is now in the final stages of its productive life. Foresting this area recovers soil for planting napier grass, a primary food source for livestock. A wetland system is introduced, reutilizing the already-existing terrain. This system serves as a reservoir of water during the wet season and as silvo-pastoral grass during the dry season.

Proposed situation
While the water catchment forest is a vital element for the downstream productive landscape, it also mitigates potential climate change impacts and is important for the upstream settlements. The inhabitants of West Nairobi develop an interaction with the natural water sources and the sharing water becomes part of the new ecological way of life.
