ABSTRACT The inspiration for this research came from a project realized by Liveinslums NGO where a dumpsite was cleaned and converted in a garden in the slum Mathare (www.liveinslums.org). Starting from this specific project of successful environmental requalification, the research explores the possibility of a intervention/plan that would work on environmental requalification at the wider scale of the entire slum. The name of the research: â&#x20AC;&#x153;Mathare Riverâ&#x20AC;?, comes from the fact that the River Mathare represents a space of opportunity for interventions in these matters and it has also functioned as guide in our spatial exploration of the slum. This book is unfolded in three parts. The first part is a report of a mapping project that has been done on the field with local stakeholders and inhabitants of Mathare. The mapping was concerning: agriculture activities, dumpsites and recycling points. The map produced was the first one of that kind in Mathare and for this reason it constitutes a very important outcome of the research. The second part of the research deeply investigates the topics of Water, Waste and Agriculture providing data and essential information for the understanding of them in the Mathare and Nairobi context. Finally, the third part of the research is focused on the strategies for environmental requalification of the slum.

INTRODUCTION “Slums constitute a foundational trope in urban studies. From Friedrich Engels to Jacob Riis in the 19th and the early 20th centuries to the 2003 UN-Habitat Report on Slums and Mike Davis’ recent book “The planet of Slums”, the slum appears over and over as a theoretically productive spatial ecology. In contemporary urban studies, the slum represents an invitation to think through both the material aspects and processes involved in contemporary urbanism and the ethical and epistemological underpinnings of urban theory today. Both are matters of equal concern as urban growth explodes across the world but particularly in countries of the global South. If a large proportion of the world’s population will be settling in cities in the global South, what does that imply for the location and the effects of urban theory? We must remind ourselves here of the intimate relation between theorizing the city and the social and philosophical project of modernity. If London, Paris, New York and Berlin provided social theorists of the 19th and 10th centuries the rich, empirical basis for creating arguments about the project of modernity, what ground do cities like Mumbai, São Paulo, Shanghai and Logos provide for a similar project today. In this essay I will explore the theoretical place of the slum today as cities of the global South begin to exert new material and ethical pressures on our understanding of global urban processes. In light of this exploration, I turn to the question of design action and its relation to the near and distant futures of urbanism.” Vyjayanthi Rao, 2010 (Lotus n. 143) 12

Vyjayanthi Rao, anthropologist researcher in the field of globalization and urban development, opens her essay: â&#x20AC;&#x153;Slum As Theoryâ&#x20AC;? with these words, highlighting the importance of considering slums in urban studies. The importance is given by the fact that nowadays slums are considered an integrated part of a city and not just as fallout, because both the geographic and demographic expansion of these slums happens to cover the 50% of the city itself. For these reasons any urban policy, which aim is to eradicate slums, becomes an absurdity. Nevertheless, the definition of slum itself has been largely debated due to its complexity as particular urban territory. What can be found in all the different definitions of slums (slum, bidonville, favela, township) is a disruption in the urban patterns from those official recognized from the respective municipalities. In the collective imaginary, the label slum is often associated with poverty, difficult living conditions and so on. Given the severe poverty conditions of the slums, the inhabitants of these areas are continuously looking for new jobs, or ways to get money on a daily base. Slumsâ&#x20AC;&#x2122; inhabitants often produce big part of the economy of the cities where they are settled. Nevertheless, the municipalities often do not officially recognize most of these economical activities as well as the same territories where slums are settled. In fact, very often there are no official maps of these territories, which make any intervention in these areas more difficult 13

to be realized. For this reason maps play a fundamental role in informal settlements and they can represent a wide range of elements such as: topography data, photos, videos, sounds, mental paths and more. It is from a mapping process that this research started in Mathare, mapping that aimed to map every agricultural activity, dumpsite and recycling point. The driving idea was to verify an environmental qualification through a series of urban acupuncture interventions, particularly addressing the garbage management and the implementation of agricultural activities. So the focus was on finding opportunities for the locals with the locals, rather than providing solutions for them. This approach has been widely described as enabling approach (Hamdi, 2010). The small scale of the urban acupuncture assures a direct confrontation with the local people, which is a very important value in this research. Thinking at the larger scale of the entire slum, all the actors, all the practitioners, all the future urban acupuncture interventions should be linked in a network, which represent another fundamental element for this research. An information is useless if not shared, and for this reason all the material included in this book are available online for everyone. Doing so, the research aims to increase the dialogue in terms of exchanging knowledge but also providing information to any 14

everyone. Doing so, the research aims to increase the dialogue in terms of exchanging knowledge but also providing information to any person interested in the studied topics. Linking back to the importance of having a daily source of income for the inhabitants of the slums, in Mathare agriculture and waste are two dimensions that can work towards environmental requalification and at the same time are possible source of income for the inhabitants (see following chapters). As it will be described further on, it is also essential a research on the specific techniques that are suitable and sustainable in the Mathare context.

PROJECT 16

As mentioned in the introduction of this book, the project of Liveinslums NGO was inspirational. Looking at the dumpsite converted in urban garden, it became clear how agriculture and garbage can work together as potentials for environmental requalification. For this reason the following pages will analyze in depth agriculture and waste. A third element will also be studied: water. This becomes very important when thinking about waste and sanitation (potable water, sewage, etc.) and also in relation to agriculture (water for irrigation). To start this study it was necessary a mapping that would involve the three elements mentioned above. We mapped gardens (agriculture), dumpsites and recycle points (waste). Map-Mathare and Map-Kibera were involved in this phase of the project. Mapping was also a way to establish relations with the local community. This fact is really important because one of the main targets of this work is to build a network among all the stakeholders involved in this research (from the inhabitant to the Ministry of Health). The last research step was focused on mapping sites for possible future interventions. These places were chosen focusing on the riverbanks.

Mapping

TOOL MAPPING

“Mathare in Nairobi, Kenya, was a blank spot on the map until December 2010, when young people of Mathare created the first free and open digital map of their own community.” www.mapkibera.org/mapmathare/

These are the words that Map Mathare community based organization

(CBO) have chosen for their website. The organization was

founded in 2009 with the intention to produce maps of Mathare. The absence of a map is one of the main problems in the context of informal settlements. Orientation is a primary need and without a map one cannot determine and view the extension and geographical localization of a certain phenomenon. It becomes almost impossible to direct and plan a requalification or redevelopment according to the present situation. In the European past, the defeat of “urban diseases” such as cholera, typhus fever, poverty, prostitution, drugs diffusion and criminality, coincided with the first production of the city plans and the emergence of urban statistics and cartographies (Else/Where: Mapping New cartographies of networks and territories, 2006, p.154). In Jai Sen’s “Power-over Power-to” (An Atlas of Radical Cartography, 2008), one can read that invisibility is not just an absence, but can be an intentional neglection. The following mapping exercise is split in two main parts. The first part 19

explores the physical aspect of the slum looking at selected â&#x20AC;&#x153;environmental activitiesâ&#x20AC;? like gardens, recycling points and dumpsites. This was possible through collaboration with two locals: Javin Ochieng and Joshua who have participated to the Map Mathare project in 2010/2011. For every point a sheet with the related information has been filled out. In the second part, there was a need to abstract from the physical reality of the slum to investigate the environmental dynamics around the slum like recognizing the stakeholders involved and exploring possible techniques to be used in further interventions. This investigation has been reconstructed and synthesized in synoptic maps in order to communicate dynamically and visually the multi dimensional analysis that was conducted.

WATER It has been estimated that 40% of the water provided by the city council is used through informal connections [1]. Monthly an inhabitant spends an average of 437 KSH for domestic water [2] and only 10% of the inhabitants of Mathare have running water at home [3]. According to Spere Humanitarian Standard the minimum number of people per water point is 250 [4]. In Mathare this value is not respected because there is one water point per 315 inhabitants [5]. According to the Mathare Zonal Plan It has been estimated that the reconstruction of the water system costs 540,000 USD [6]. The Mathare River goes longitudinally across the whole slum. The riverâ&#x20AC;&#x2122;s water is not being used due to the high pollution level known to everybody (the inhabitants call the river â&#x20AC;&#x153;coca cola riverâ&#x20AC;? because its colour is very similar to the dark brown colour of coca cola). There are mostly two causes for this pollution. First, there isn't a proper sewage system for the settlements therefore all the liquid waste flows directly into the river. Second, most inhabitants throw garbage into the river although there is a risk of getting arrested by the municipality if caught in the action. Nowadays there are many studies about the Nairobi River and therefore Mathare River being part. The most important study is the Nairobi River Basin project, done by UNEP (United Nations Environment Programme), Government of Kenya, UN-Habitat, UNDP (United Nations Development Programme), the private sector and civil society. The vision of Nairobi River Basin Programme (NRBP) is a restored riverine eco-system with clean water for the capital city and a healthier 63

environment for the people of Nairobi. One main point of this project is the “riparian zone” restoration, which is the interface between land and a river or stream [7]. This zone is 30 meters wide as defined by the NRBP [8]. It is now is partially occupied by houses. If this area had to be liberated there will be approximately 22,146 people evicted with 1,116 structures demolished of which houses, schools and churches. Instead Mathare Zonal Plan proposes an intervention that uses more the empty areas along the river. Doing this it is possible to maintain almost all the houses along the river with a demolition of only 147 structures. The global population growth represents an alarming issue for the depletion of water resources more than climate change [10] and the problem is that this amount of water is unequally distributed over the planet. Norway has 82,000 cubic meters of water against 830 cubic meters in Kenya [12]; nevertheless “virtual water trade” represents a solution to this disparity [11]. Even though there are several projects done by the World Bank and International Monetary Fund on this matter, Peter Gleick criticises the fact that often these institutions invest all the funds in one place because they are not able to use them in many other places [13]. Solutions aside, the issue of global water sources is really important and represents today’s real war [17]. If for any reason the water disappears the human race would become extinct in few days [18].

FLOODS AND BUFFER ZONE (DEF. NRBP) During floods some of the houses along the river are being flooded.

PROPOSALS FOR THE BUFFER ZONE BERKELEY: MATHARE ZONAL PLAN

[25] [9]

In opposition with the Nairobi Basin Project, the Mathare Zonal Plan proposes a more organic drawing of the buffer zone, which expands more in the empty spaces along the river and less in the built ones. This drawing aims to limit as much as possible the number of houses to be demolished. In addition the plan also defines what kind of functions will take place in this buffer zone. Among them, it is important to point out: agriculture, community spaces, reparian vegetation and a path along the river.

agriculture community spaces vegetation path

ETH: GREEN CORRIDOR [26] In 2008 studio Basel (ETH university of Zurich) proposed a project on Mathare River and its banks. They propose to create an ecological corridor (green) along the Mathare River. The idea is to connect this corridor with other planned corridors designed along the other rivers of the Nairobi district. These corridors will connect very different areas so the idea of the project would be also to create more social cohesion among different communities.

agriculture Urban agriculture plays a fundamental role in the economic development of cities of the “Global South”. Within this context, there are several projects based on agriculture as a tool to overcome certain obstacles. For example both in Kibera and Mathare the French NGO “Solidarités” has implemented an agricultural project to resolve the problem of food security, which at that time was a stressing issue due to the economic loss after election clashes of 2007. In fact urban agriculture is able to provide solutions to economical problems since it is a productive activity able to generate livelihoods. The implementation of projects in informal settlements of the Global South needs to face the challenges related to poverty and in particular to the need of sources of income for the inhabitants of these settlements. Urban agriculture has the potential to produce income and it is perfectly adapted for operations of urban acupuncture. This is due to its applicability either on a large or small scale, as well as the various ways in which urban agriculture activities may be carried out (individual or group work). In addition many of the inhabitants are familiar with agricultural practices because of their cultural origins (most of them come from rural areas where agriculture is a common practice). This research provides a fairly wide scope around all the topics related to agriculture like: seasonality, irrigation, agricultural health, soil engineering, etc. For instance in the following pages a study about the common diet of the inhabitants is presented in order to understand what kind of products to integrate to fill up their nutritional deficiencies. The investigation of the adopted agricultural techniques is essen70

tial to draw connections with other problems like: soil pollution, space availability, flood risks, etc. In fact, this could be resolved through adequate technological solutions, research and education. Shortly, towards an environmental requalification of the slum, agriculture is a great tool to control and protect riverbanks (riparian zone) that now are often in critical conditions. The idea is to recreate this riparian zone using interventions of urban agriculture situated along the Mathare River so as a way to stop the waste deposit. In addition, working on the riparian zone has to deal significantly with ecology, environmental management, and civil engineering because of their role in soil conservation [4]. Furthermore it is important to point out that the climatic and geographic conditions of Nairobi are in favour of agriculture: high solar radiation, optimal temperature and humidity for plant growth that are quiet constant during the whole year [5][6]. In the contemporary debate on cities it is repeatedly reported how urban agriculture has even an important social value, being able to establish new relationships among people [7]. This value has been proved during our research because we have found many youth group working together on agricultural projects. Last but not least, the spatial quality of agricultural projects is really important: to a master plan level, agriculture in Mathare can actually become a mean to direct the slum expansion towards a landscape one, beside the integration between nature and city that occurs, it can offer a lot of possibilities to public space design and positive use of space. 71

EXISTING REPARIAN VEGETATION

waste Waste has a striking presence in Mathare: it is scattered in various areas of the settlement and represents a high risk for the health of the inhabitants and the environment. There is no form of garbage collection for both the liquid and solid waste. In a controlled environment, liquid waste is collected using a sewage system where there is a distinction of the source (organic and chemical liquids are separate) which allows different treatments before their reintegration in the environment; while solid waste is collected according to their material nature then recycled or burnt to produce a different form of energy. Nevertheless in Mathare there is not a base infrastructure system to allow these operations to take place. Concerning the sewage system in Mathare, one can find traces of an old underground system that is not in use nowadays, as mentioned: â&#x20AC;&#x153;the sewage pipe system is in total disrepairâ&#x20AC;?[1]. What happens instead is an open-air drainage system that collects liquid wastes from all the temporary dwellings and the public toilets to discharge them in the Mathare River without any treatment, which is strongly polluting the water. As a result many bacteria have spread like Cholera (Vibrium cholerae) for example that is responsible of a large number of deaths. A recent appraisal present the total cost of KSH 80,2 M = US$ 945,000[2] for all the pipes and new hygienic blocks in big part of the slum. Dumpsites of solid waste are found in several locations in Mathare: beside the roads, in between the houses, on riverbanks and potentially every empty spot. The extended deposit of materials seriously affects the environment: organic waste fermentation releas78

es poisonous gases that can seriously damage the human breathing system. Fermenting waste in Mathare is usually referred to as “boiler” because of the heat and accompanying noise it produces. During the dry season the piles of solid waste can catch fire autonomously. Also the sedimentation of heavy metals and other irritating or toxic substances pollute the aquifer. The situation of the dumpsites for an external observer could be identified as random and one throws wherever he wants. Whether several conversations with the locals pointed out that there is a certain system or set of rules that the inhabitants follow in order to be allowed to throw garbage in a specific site. Generally speaking, the absence of a public collection service in the slum is the reason for the permanence of this situation. The waste management issue represents an obstacle not just for Mathare but as well for the city of Nairobi in general. The public services and investments cannot deal with the situation. The city dumpsite is too small and lacks any environmental measure and the private companies are expensive and penalized by the law. In addition recycling is not supported. “The Council doesn’t seem to accept the responsibility it has and to acknowledge the seriousness of the current situation.[4]”

LOOKING FOR GARBAGE

It is common practice amoung the youths to look for plastic and metals in the dumpsites of Mathare. These material will be sold to industries for recycling.

recycling COLLECTION POINTS

There are different garbage collection points in Mathare, often specialized by material. They function as intermediaries from the slum to the recycling industries. They give money in exchange of recyclable garbage. Mathare

Techniques For all the issues explored throughout this research, many techniques were also mapped as fundamental tools for the different activities of agriculture, recycling and garbage management. Nevertheless it is also important to study further technical solutions that can solve certain issues still problematic in Mathare. For example, a research on techniques to purify the water would be very helpful in the context of agriculture in Mathare. To power or teaching new techniques is enormous if thinking that a single technique can solve more than one problem and often it might bring new opportunities. Obviously whenever a new technique is introduced in a new environment, such as Mathare, this needs to face with the feasibility of it in that specific context. This means, looking at the availability of resources, the expertise of the inhabitants and so on. Therefore it is important to position a simple technique learned from a farmer in Kenya at the same level of a very innovative and technologically advanced solution. Only if the exchange of knowledge and expertise happens in this equal way, sustainable solutions can be found. On the website is possible to find some of the techniques researched (www.mathareriver.wordpress.com).

stakeholders With the term stakeholders, this research includes every single person or group who interacts with the project in all its phases. Following a simple classification, which depends on the role every stakeholder covers, it is possible here to distinguish between beneficiaries, donors, cooperators and so on. This classification is a simplification of all the different roles that actors can play, but it useful here to keep in mind all the possible expertise that can be involved. Because of its nature, this section will continuously evolve and enrich every time new connections with actors are established. It is important to underline that a stakeholders is not just someone present on the field but also any person involved or just interested in the project (i.e. supporters). The idea of this section is to be again open for everyone who is interested in looking for actors involved in the three topics threated: water, waste, agriculture.

Networking

Necessary prior the establishment of a large-scale environmental strategy is the creation of a strong and active network of stakeholders to support it. In order to create a network, communication plays the major role and for this reason the communication strategy needs to cover different areas or aims: create awareness, share knowledge and information, put people in contact. To start this networking process a blog has been created where to publish all the activities related to fieldwork and elaboration of the collected data. At the end of the first mapping phase we organized a meeting with all the stakeholders involved in this phase in order to have a first feedback from the data and experience collected (look at â&#x20AC;&#x2DC;Flyer Meetingâ&#x20AC;&#x2122; to see the topics of discussion). During the meeting was highlighted more than once the importance of creating events of awareness in the slum around environmental topics. To enhance the impact of the meeting we donated t-shirts and seeds to all the participants.

proposed vision

106

As mentioned at the beginning of this book, the last phase of this work was focused on the research of possible sites where a future intervention would be possible. The site were chosen and mapped according to the following criteria: proximity to the river, stakeholder known on site, current use of the space (prioritizing unused spaces or dumpsites). The decision of focusing on area along the river comes from the fact that these areas are the ones more suitable for the environmental requalification purposes. In fact, it is along the river that most of the agricultural activities are located as well as dumpsites. In support of this, there is also a limitation from the City Council of Nairobi that does not allow the construction of any building on the riverbanks but the only permitted activity is agriculture. For this reason combined with the risk of having a house along the river (flooding), the areas along the river are mostly empty and therefore suitable for projects of environmental requalification such as the one that inspired this research (conversion of a dumpsite in a garden). The following pages describe in details each site of intervention combined with the possible activities that can happen in these areas in respect of what discussed throughout this book (i.e. agriculture, recycling, info point for knowledge sharing and networking, etc.). These activities need to be taken as hypothesis that then need to be verified on the field when planning a real intervention.

The panels include a detailed map of the collected points plus a representation of the built environment along the river banks. The panels also include most of the pages of this book which are connected to the map where needed. For example all the sheets describing the gardens mapped are linked with a red wire to the point on the map where the garden is located. On the map also the vegetation along the river is represented using different graphic codes according to the type of vegetation present (grass, bushes, trees). 126

pilot project With the material of the research, together with Liveinslums NGO, we were able to get funds to realize the pilot project proposed in the research (as described in the previous pages). During the summer of 2013 the pilot project called Mathare North Community Garden started. After few weeks of investigation on the field, the site number 13 (see previous pages) was chosen as the most appropriate to set a pilot project for the Mathare River research. The discussion of the pilot project, started with the actors involved in agriculture or in recycling activities, who were involved in the research in 2012. The pilot project we agreed was a community garden in Mathare North that was gonna give food and income support to the Mathare North Primary School and to the youth of Mathare North. The drawings on the right show how from the research we went to the specific area and after some work on the field a preliminary plan was developed. The site work started with the help of some youth groups from Mathare North. The engagement of these groups was very important due to certain challenges that we encountered during the project. This aspect touches upon an important element that was highlighted in the research: the use of local knowledge. In a month of work 1000 square meters of garden were built and planted. The garden was meant to function not just as element of environmental protection, but also as an income generation source. This connection worked on the issue of food security that was one of the requirements from the donors. The garden was provided with pipe water, fence, gardening 128

tools and devices, seeds and a shed for meetings. Once the construction work was completed, we organised several meetings to discuss about the future management of the garden. The idea was that the vegetable products of the school garden were going to be used by the kitchen of the school to improve the diet of the students. For what concernes the community garden the idea was that the members of the project were free to decide either to eat the products or to sell them. This allows them to save money in case there is any replacement of material needed in the future. Obviously some challenges came up and for this reason, we kept a continuous dialogue with the local members. To do so we also added the members of the project to the Facebook page so that they can post comments or pictures about the status of the garden at any time.

conclusion This book showed a story of a research started in 2012 and still going on today. As represented in the last pages, in 2013 a pilot project was realized thanks to the material produced during the research. Looking at this project one year after, we learned a lot and the idea is obviously to continue to implement the vision proposed by this book: environmental requalification of Mathare through acupunctural interventions. The pilot project showed an example of using agriculture for this aim, but a lot can be done. For example an urgent need in Mathare is to face the issue of garbage collection and management. These are the issues on which this work will continue to work in the future.

134

Thanks to all who took part in this work, with the hope of continuing the collaboration, the sharing of ideas, dreams, hopes around Mathare.
