Project Summary
Are our cities prepared for the growing and rapid urbanization expected for the coming years? How do the new social, economic and environmental challenges affect the urban context, specifically informal settlements? How can we rethink sustainable urban design in vulnerable areas? To tackle these questions, this study will have a closer look at Port Elizabeth, a coastal city in South Africa, to understand its relevance and challenges. By landing at a specific informal
6
settlement, this degree project will reflect on how collaboration is a crucial element for urban design and how it is essential when working with complex communities. These reflections will be summarized in a design proposal for a South African present informal settlement, by promoting resilience towards social inequality and climate change. It will also aim to create opportunities by, strengthening local democracy, rethinking urban infrastructure and creating development.

Introduction: A global phenomenon Vulnerable urban development is an alarming problem, but not new. Moreover, it is also not restricted to a specific place. While the number of people living in slums is slowly decreasing due to extensive affordable housing programmes, there are still nearly one billion slum dwellers around the world.

Western Asia
Oceania
Asia
Sub-Saharan Africa has the largest number of slum population, amounting nearly 200 million people, this number being closely followed by Southern and Eastern Asia, as well as Latin America, where the number of slum dwellers is lower, with just over 100 million. In September 2000, world leaders along with The United Nations have gathered to develop a series of goals for
humanity at the dawn of the new century. Along these goals, there has been one stipulating that the aim will be to “significantly improve the lives of at least 100 million slum dwellers by the year 2020.� This could be achieved by upgrading the current housing systems as well as developing policies and strategies to further prevent people from settling in these areas.

1.1 The definition of informal (human) settlements
What are slums and informal settlements? While there is no single, universal definition for what we call “slums”, generally speaking they are neighbourhoods that are to a certain extend categorized as sub-standard and do not meet the minimum requirements for what we can call a reasonable standard of housing. UN-Habitat has defined them as an area that meets one or more of these following characteristics: poor level of structural quality of housing, inadequate access to safe water, overcrowding, poor or no access to sanitation and other elements of infrastructure, insecure residential status.
Poor structural quality of housing
Overcrowding
Inadequate access to safe water
Inadequate access to sanitation and other infrastructure
Insecure residential status
Informal Human settlements Lorena Zárate, President of Habitat International Coalition, defend the right use of the term “Human settlement” instead of “Informal”. It might seem a matter of terminology, but attributing the notion of irregularity to a specific group or place implies the idea of disqualification of the problem and therefore, the ones surpassing them. It is urgent that, in a broader context, the qualification of the discussion narrows the concept as precisely as it is: human.

A slum consists of a household or a group of people living under the same roof lacking one or more of these five amenities

The phenomenon of urbanization, when studying the past, occurred in what we now call the “two waves”. The first of these waves occurred in what we call “global north”, having its initial traceable around 1750, where the urban population of global north reached the 15% mark, with 10 million people living in cities. Thus, the urbanization process continued gradually and palatially, reaching the tipping

point in 1950, with 52% of the population now in urban areas, representing 423 million. This date also represents the solid start of the second wave of urbanization, which takes place in what we call the global south. However, this second wave is projected to happen in a substantially shorter time interval, and with a much more impactful scale. While the global north urbanization process took about 200

years, in the global south it is projected to happen in 80 years, and on a scale of 309 million to 3.9 billion at the end of 2030. The prospects of 2050, it is estimated that the urban population will more than double, at the mark of 9bn. The middle class population more than double, while the share that lives in vulnerable areas will triple.

1.4 Urbanisation benefits
Even with the urban growth scenario representing one of the most significant challenges of modernity, the urbanization process throughout history is seen as a significant advance. In urban settings, the population experiences an improvement in essential aspects of life. Whether by the economic, social or educational aspect, in urban environments, the individual has access to health services, qualified job possibilities, education and sanitation. Thus, despite the phenomenon of vulnerability and disparity caused by rampant urbanization, the urbanization process itself is seen as a positive aspect of our evolution and has caused significant benefits.

WHY IS AFRICAN URBANIZATION DIFFERENT? Edgar Pieterse, the Director of University of Cape Town’s African Centre for Cities, has a significant work on the field of African urbanization. His studies, together with major agencies and the UN-Habitat had suggested that the benefits and the urbanization process occurred differently in African countries, leading to conditions fundamentally different from the rest of the world. The question is: why?

Realities of african cities
Long term under and mal-investment in cities and urban infrasctructure
Turnkey projects driven by new investors often produce unsuitable outcomes; gated communities, malls, highways and other vanity projects to boost profit
A significant phenomenon that occurs in different regions across Africa is the alarming levels of the populations living in slums. This situation is the result of an initial condition of the long term under-investment in necessary urban infrastructure. It creates cities with chronic conditions and problems. This lack of investment causes
Immense pressure to address massive infrastructure backlogs through quick and dirty investments
Net effect: dramatic sprawl, ecological degradation, increasing spacial and social divides and under-investment in slum areas
a social and political pressure for the governments to accept any sort of external or private investment, creating what we can observe the other reality of African cities: the occurrence “dirty investment�, launched by the private sector with profit as the primary target. As a result, this investments creates what urban planners and urban designers all want
to avoid; a variety of gated communities, shopping malls, highways leading to nowhere and so on. These investments and projects further aggravate the situation of segregation, increasing the gap between the rich and sparse population. The concentration of income affects the most vulnerable population, living in periphrases of the cities.

To understand the scale of the demographic challenged presented in African societies, it is necessary first to observe the future trends of the demographic transition that Africa will go through. Currently, around 50% of the African population is 19 years old or younger, and it is anticipated that over the next 40 years the labour force will grow from 400 million to 1.2 billion, leading to a total increase

of more than three times. Currently, 63% of urban employment is considered vulnerable activities. It is also anticipated that the proportional growth of that informal employment will occur in the vulnerable employment number. Specialists have pointed concerns with this significant demographic shift that will be experienced in Africa, as the primary employment, liveability,
opportunities and demands for this new demographics scenarios might not be achievable unless a significant change to political and social aspects are promoted. This phenomenon leads to a more challenging scenario: the economic and employment predictions. As the African workforce will triple over the next years, it is uncertain that new job opportunities will follow the same pattern.

2.2. The economic and employment challenge

The economic challenge presented by the demographic shift can be visualized by looking at the employment period of 2000 to 2010. By the year 2000, around 65% of urban employments were vulnerable activities, such as informal work or family business.

The African GDP growth rate statistics show dramatic economic growth over the last decade. It has experienced the most rapid growth of all countries, besides China. An interesting point to observe is that, by looking at the same employment statistics for 2010, it is possible to observe that vulnerable employment was in about 63%, experiencing a decrease only of about 2%. It concluded that the dramatic GDP growth that the African economy experienced between 2000 and 2010 did not have a significant impact on the number of population vastly involved in vulnerable employment. A first point that leads to significant concerns about the inability of providing stable employment conditions to African cities regardless the economic growth is that, with the demographic shift, this trend is expected to become a chronicle condition. Secondly, this phenomenon creates a condition of slum urbanism.

Experts point out that “the inability to generate sufficient wage-earning jobs lead to the fact that most households will be unable to afford to live in a formal house, pay taxes or contest the ‘rules of the game’ when it comes to formal politics”.

2.3. Africa slum urbanism
Inverted economy: Majority informal Demand for services outstrip suply
Low or erratic incomes
Skewed allocation systems
Small taxes base
Insufficient private & public investment
The logic for the current scenario of African cities has as a starting point a logic of inverted economy: a concept in which the majority of activities and goods produced by the society are mainly informal. The economic informality leads to a low level of income rates for families and society in general. As an essential economic engine is allocated in the families consumptions of goods, this economic pillar
is yet damaged by the informal market. As a consequence, lower rate of taxes forms a shortage of a proper economic public base, with governments struggling with major taxation depravations, leading to the fourth phenomenon: the shortage of private and public investments in critical public sectors and services. It is not only the lack of investments that is a significant
Sources: UN Habitat | Susan Parnell, Edgar Pieterse, Africa’s Urban Revolution Paperback, 2014
concern, but the limited amount of investments is also scared in dirty and political purposed investments. This cycle creates a logic scenario in which the demands for public services, infrastructure and cities goods aways overcome the supplies, leading to an increase of informality in housing, employment and city planning, in a vicious cycle of slum urbanism.

Stunted social mobility
5. Competition for resources and control

Precarious low wage work
Low household incomes
6. Erosion of social cohesion
The vicious cycle created by slum urbanism in Africa is well defined by the presented Vortex of exclusion. It states that one phenomenon gives the conditions or leads to the significant results of the next event, in a cycle that is difficult to break out from or to legislate against. It creates a dysfunctional urban reality in which the formal and informal, the planned and the unplanned and the governed and the ungoverned co-exists. 26

As the structural conditions presented leads to a scenario in which slums urbanism is ha significant phenomenon, specialists in the urban African development also denominates the lack of public services and investments that creates the second and more alarming condition, the splintered urbanism. This condition is the combinations of slum neglect with enclave elite urbanism.
Land
Edgar Pieterse presents the following definition:
“Splintered urbanism is a concept that captures the interrelated dynamics between the privatisation of key public services; the fragmentation of urban geographies between those who have access (a minority) and those who don’t; and the inevitable production of under-services areas known as slums.”
Sources: UN Habitat | Susan Parnell, Edgar Pieterse, Africa’s Urban Revolution Paperback, 2014
The combination of factors presented leads to a structural obstacles reality, in which: Limited state understanding to address urbanization; regulation to penalize informality; small and skewed formal economies - limited tax base; Most African countries manifest very limited substantive decentralization; and finally the costs of largescale dysfunction paid by ‘voiceless’ slum dwellers.

The present condition of African urbanism and the logic of creating vast portions of informal society can lead to an uncertain future. With the increasing demand for urbanization, the growth of urban population and the fast tipping point of urbanization, it is anticipated that the total number of city dwellers in Africa will surpass the rural population by middle 2030s, and it will lead to a significant

increase until 2050, creating a long stand condition. The presented research shows that urbanization of poverty, as manifest in slums living conditions, combined with precarious employment, lack of public and private investment, political uncertainty, is the norm. This condition is encrusted in African society, despite the high rates of GDP growth, and the scenario is not shifting fast enough. As we continue in the study, most of the African population are exposed to fundamental privations, in incredible precarious lives. This condition is yet to have is specificness on each African country, but the main struggle is shared by African society as a whole. We can identify the pattern, but we do not know the specifics. However, one of these countries has a very particular case to add on top of the urban informality conditions. It is the country in which is the subject of this thesis; South Africa.

Fifty-eight million habitants, a wide-ranbe of ethnic groups, eleven official national languages, the risen and fall of a segregative regime, breathtaking landscapes and a climate challenge. South Africa is indeed a country with unusual combinations of elements that add to the discussion. For the focus of this study, and as an addition to the global perspective, two primary focus about South Africa will be highlighted, as it follows. 31

The poorest 60%
Hold 71% of total wealth

Poverty: who is affected More than half of South Africa’s population (55%) live in poverty (less than $83 a month) 25,2% live bellow food poverty line (less than $37 a month)

While democracy has redefined freedom for all South Africans, not enough has changed in the past two decades for those living in the country’s vast townships. In fact, South Africa remains the most economically unequal country in the world, with more than half of South Africans (55.5 %) living on less than $83 a month. Income inequality may be a problem, however, the real issue is the unequal access to opportunities
32
and essential public services. Mthandazo Ndlovu, Oxfam South Africa’s representative blames these concerning levels of inequality on the government and its continuous failures to implement a system that truly works for everyone. He has also stated: “One would have assumed that 25 years into democracy we would have had better access to land, better access to health care, we would not have children falling into
pit latrines due to failures in the provision of ablution facilities.” South Africa’s inequality scenario became especially known worldwide after a vast work developed by the photographer Johnny Miller. The Unequal Scenes is an initiative that captures the essence of the disparity between classes, and it has marked its presence on the front page of the Time magazine.magazine

3.2 The climatic challenge
The climate change impacts are already part of the world reality. Extreme weather conditions are being reported from different areas around the globe, and even though climate change might not be appointed as the direct cause of some phenomena, it increases the likelihood and the intensity of extreme weather events. In South Africa, extended drought periods that occurred at 150year intervals are already
projected to happen every 50 years. A recent and prolonged drought period in Cape Town has raised concerns that it might have a direct impact in urban life, especially in socially vulnerable areas, raising inequality to alarming levels. A recent Habitat for Humanity study shows that 900 million people are living in informal settlements worldwide with limited access to basic services. Some experts predicts that this
number might rise up until 1.6 billion, representing Âź of the global population, if different types on informal settlements are considered. A World Bank estimation points out that South Africa has the worst economic equality in the world. The water shortage, due to climate change, is expected to increase the division between social classes even further, as the resource might not be accessible for all. According
Image Source: Weetracker, Drought to blame for rising suicide cases among farmers new initiative unveiled will partly solve this, 34
https://weetracker.com/, 2019
03 | The South African Context | 2020
to Giulio Boccaletti, Nature Conservancy’s global managing director, “Inequity plays out in water very obviously, and what we’re seeing in Cape Town risks becoming an example of that”. Climate change is expected to lead to other extreme events in South Africa, according to a study by the Climate Systems Analysis Group of the University of Cape Town. Despite the decrease and seasonal changes of rainfall, a higher average temperature and more frequent and intense heatwaves are expected to take place. Higher wind speeds, increase of storms frequency and sea level rise are also pointed on the study. These events will lead to direct impacts on the city, especially to socially vulnerable areas, such as informal settlements and slums. Some of these events are already happening, for instance, extreme storms leading to flooding and settlements destructions. Water being a scarce resource is a problem not only restricted to major South African cities. A report published by the US intelligence predicts that global water consumption will exceed he supply by 40% until 2030. In this scenario, urban design and solutions towards climate resilience, especially in vulnerable social areas, will be an increase in demand.

Located on the shores of Algoa Bay in the Eastern Cape Province, The Nelson Mandela Bay Municipality is one of eight metropolitan municipalities in South Africa. It is and comprises the city of Port Elizabeth, the nearby towns of Uitenhage and Despatch, and the surrounding rural area. Having a population of 1,152,115 (census 2011), the municipality is considered an important hub for tourism and natural reserves.

The central municipality city is Port Elizabeth, that corresponds to the main municipal area. The Nature reserve parks, especially along the bay, are the main attractive points for tourists, nationally and internationally. Highways and avenues are primary connections to the municipality surroundings, as well as to the rest of the country.
Tourism represents a vital economic sector, which has increasingly contributed to job creation in recent years. The main reason is the municipality’s seaside location and its abundance of unspoiled beaches. The municipality has an airport that connects the city to important centres, such as Johannesburg, Durban and Cape Town.

4.3 The Apartheid urban planning Port Elizabeth
South Africa has one of the most dramatic racial segregation movements seen in history. The impacts of segregation are reflected in various forms in South African society to this day. Port Elizabeth had a fundamental role in what was called “The Apartheid Urban Planning model�, a method that aimed to establish specific access regions of the city according to racial differences. The model of racial segregation adopted from the Port Elizabeth planning method became a reference for other locations, where the black population, mix races, Indians and Asians were displaced outside urban centres, towards the northern region, as can be seen from 1910 to 1950.

The results of Apartheid’s urban planning are seen today, as the freed society is struggling to overcome the chronic segregation of the past. The 2011 Tapestry social survey conducted by the South Africa Department of Statistics shows that racial division by neighbourhood is still profoundly accentuated. In the study, people who perceive themselves white live predominantly in the southern
region of the city, with access to neighbourhoods equipped with urban infrastructure, access to beaches and natural resources. The northern areas, historical regions of the apartheid era, continue to be predominantly inhabited by the black African population. A large portion of this population lives in neighbourhoods with insufficient infrastructure coverage and far from the urban centre.

Currently, eight main informal settlement is being studied in the city. These studies are the result of joint action by Nelson Mandela Bay Municipality, together with the Eastern Cape Department of Human Settlements (ECDHS), the Mandela Bay Development Agency and with support from Nelson Mandela University. The purpose of this partnership is to create a set of legal, political, social and research
actions that enable the study, analysis, proposition and possibility and socialization of these settlements. Each of these different communities has similarities in fundamental weaknesses, but with varying degrees of complexity. There are also central points specific to each location. making planning work much more complex.

part 05
I want to start this chapter with a personal reflection without leaving the academic purpose of this analysis. When I set out to study the case of urban development in vulnerable areas more carefully during my Bachelor, I found myself several times reflecting if such complex and structural problems of Brazilian urban life would be a unique case in the world, or if its causes and results can also be seen elsewhere in the world.
It is curious how life ends up unfolding: That memory caught me at 3 am, in the middle of the flight between London and Johannesburg. I am writing this reflection, going to a continent I have never visited, precisely to see with my own eyes how the social vulnerabilities inherent to the neediest population are shared in a global phenomenon.
Most touchingly of this reflection, now tracing back the situation, my visit to South Africa was an experience that I will carry on as an extraordinary moment of my academic and personal career, for the rest of my life.

5.1 The city Study visit | Port Elizabeth March 2020
The visit to the Nelson Mandela Bay and Port Elizabeth took place between the 4th and the 14th of March and was the result of the partnership between Lund University and Nelson Mandela University. The visit was led by the Development and Human Settlements Department and the architecture department at Nelson Mandela University, through their representatives, Professor Sijekula Mbanga
46
and Professor Paul Makasa. To better organize the flow of what was seen during the visit, we will list four significant categories for the visit, the first of which is my account of the city. Having an urban network that spreads over more than 30km along the coast of the Eastern Cape, the city of Port Elizabeth has a rich mixture of urban spaces, relaxation, nature and recreation, being
predominantly marked by its strong connection with the sea and the old port facilities. The city is known by South Africans as the ‘friendly city’, which refers to the “lay back” mood of an ‘easy city’. In addition, the city has a vibrant mix of layers of history, with buildings dating from the early eighteen hundreds, and antiapartheid era, in addition to contemporary development.

5.2 The nature Study visit | Port Elizabeth March 2020
The natural landscape is one of the most attractive points in the city. Several times I found myself walking around the city being guided by the sound of the sea, the singing of birds and the vast diversity of parks and green areas. In several areas of the city, nature and the urban fabric mix together. It is a setting in which it is difficult to establish where the urban fabric ends and
48
where the exuberant nature begins. Several hike spots in the region can be accessed within 10 minutes from the city centre, making the city an ecotourism hub for South Africans and also for international visitors. With the greater emphasis for visitors, are the beaches, which are preserved and clean, the main one being King’s Beach, where the Pier is located. Less than a 15-minute drive from
the city centre, to the south, the Cape Recife Lighthouse Natural reserve is a famous bird-watching destination, with access control for visitors. The dunes along the coast, along with the linear park are also part of the highlights of the city’s natural resources.

5.3 Workshops and meetings with local agencies/authorities Study visit | Port Elizabeth March 2020
The collaborative aspect of the work is the most critical asset of the study. The collaboration among different organizations proved to be the key to the success of future public policies that will result in the transformation of the human settlements scenario in the region. As an essential part of the research, I had the opportunity to visit several governmental agencies, research, workshops
50
and various actions. The following is the list of agencies visited, meetings, workshops and actions promoted during the visit:
- Mandela Bay Development Agency; - Land Use and Planning Department;
- Nelson Mandela University;
- Human settlements visits;
- Eastern Cape Department of Human Settlements (ECDHS);
- Community leaders meetings;
- Nelson Mandela Bay Municipality;
- Workshop on assessment of informal settlements;

5.4 Walmer Human settlement 1 | Study visit March 2020
We visited two human settlements in the region. The first was Walmer, a community located about 4 km from the city centre. This community is located in the security area of Port Elizabeth Airport and is considered a risky and unsuitable area for housing. Another risk point for the community is the high concentration of methane gas found in the soil in some regions, with a probable origin
52
of the old landfill use in the area. The community is going through a gradual process of urban recovery promoted by the municipality. The housing RDP program is partially implemented as well as basic infrastructure, such as some paved streets, clean water and a library. The number of households is uncertain, but it is estimated that 500 families live in the community today.

5.5 Vistarus (chosen design site) Human settlement 2 | Study visit March 2020
The second community we visited was Vistarus human settlement, which will be the object of the indepth study of the project proposal for this thesis. The community is located 13km from the city centre, being established close to the Nelson Mandela University MissionValle campus. The proximity to the university allows significant strategic advances for the
54
study of the community. Another point to note is that this community has a committee of residents who take care of the administration and the interests of residents in the region, in addition to having a strong connection and proximity to the Care Center Vistarus, which supplements the community with essential services. The community is also located close to schools, a hospital and a commercial area.
05 | Study visit | 2020
55
We were welcomed by the community members, who showed us the area in detail. I had the opportunity to talk directly to the residents of the community. It was an exceptional opportunity to exchange ideas and understand a little more about their realities and needs. The process of starting with community members is essential to a collaborative design process. Most of the residents are unemployed and unassisted, which leads to high levels of social vulnerability.
56
05 | Study visit | 2020
It had rained on the morning of the day of the visit, as well as the day before, which was interesting to observe the weaknesses and the dangerous sanitary conditions of the community. As torrential rains are frequent in the region, especially in the summer, most of the shacks are impacted by the result of the rains. Some houses are partially or even destroyed. Circulations are also difficult to access since there are no paved streets or passageways.
The community has limited access to water. Supply points are scattered throughout the community. However, they are few and present fundamental sanitary problems. When water is needed, community residents use buckets to capture water at these access points. Moreover, water rationing happens frequently, and water quality is not ideal for consumption, leading to health and underlying sanitation problems.

The study visit, as well as research on the city and the impacts of national and global effects on Human settlements, enabled a detailed analysis of the community.
The main points raised were the circulation axes, the areas of access to the site, the circulation conditions, the main functions around the site and the physical issues of the place.
After surveying the number of shacks and their positions, the community flowchart and its main circulation axes, the analyzes were developed to understand the area.
An analysis of points of interest and nodes for the community was also possible based on data collection and interviews with residents.
59
6.1 Site location
The site is located 13Km away from the city centre, having one of the main north highways as the primary connection point. The main transportation method is the “taxis�, minivans privately owned and responsible for the primary connection between the neighbourhood of the city centre. There is a lack of sufficient transportation method, which leads to a difficulty for some to connect to other municipal areas. 60

6.4 Site History Development
There is no exact known date for the community establishment, or the people moved from, but investigations led to the conclusion that the community was established in 1999, with people moving from a former apartheid township that was deactivated. During the study visit, I had the opportunity to have a meeting with the Land Planning Department, in which I was presented the historical
satellites photos of the area. Investigations from 1998, it is possible to see the site with no occupation, and in 2011, the community status as we know today. The physical organization of the main flows established for the community follows the existing natural paths, as we can observe by comparing both images.

The site has an exciting range of functions in its vicinity, such as Nelson Mandela University to the north, a hospital, a school for the hearing impaired to the south and the Missionvale Care centre to the west, an important node for the community. As the primary institution of help and support for the community, the Care Center promotes activities such as workshops, qualification of manual labour, computer
courses, urban farming, and a clothing and food donation network. The main access roads to the region are paved, with the main avenue to the south and the highway to the north. However, all internal displacement to the site is severe since there are no paved roads. Circulation is complicated mainly in times of heavy rain.

The topography is a striking element on the site, especially in the central circulation axis. The in-depth study made it possible to understand how the main circulation axes within the site are, as well as which are the most important nodes. Among the central circulation, areas are the Care Center, the primary school on the other side of Highways and the open area for community discussion meetings, marked in point F.

6.9 The municipality site plans
The municipality has several plans in progress for the site, which has been going through the legal process of urban planning. The current plan is in version number 6, with previous versions also providing for a mix of social housing, RDP housing and commercial activities. The municipal plan and legislation for the site limits the number of households to 587 families that can be accommodated on the site.

6.10 The RDP housing program
The Nelson Mandela Bay Housing Development Agency (HDA) is the institution responsible for the RDP housing program for human settlements in the metro. The program aims to empower the communities and to provide access to formal urban infrastructure, paved streets, sanitation and housing. The housing program has a fixed model in which has three main bedrooms, a

bathroom and a cocking area. The RPD housing is an essential program to the area, that lead to advancements in different communities, such as the Joe Slovo community presented on the photos. However, there is still challenging to innovative urban design, as the program is designed with the traditional free house stanging model, not adapted to the different families needs.

Social vulnerability
Inefficient political regulations
Climatic risk
The first issue that needs to be addressed before starting to develop strategies is to understand the problem. The research so far has shown that the South African context of urbanization has led to a logic of producing informality. Within the design language, we can summarize this picture if we imagine a diagram where,
Quality urban life (vision)
on the one side, we have informal area residents, and on the other, a house. The house here represents the urban achievement of a dignified life, with infrastructure, recreation, economy and culture. Between the two sides of this diagram, we have the separating barriers. These barriers vary from historical urbanization
contexts, severe economic informality, lack of investments and social policies, climate change, historical segregation and social vulnerability. The design strategies aim to overcome these barriers. Although these barriers are often untouchable, they are not indestructible.
73
7.2 STRATEGY 1: The Bottom-Up approach
increase opportunities
decrease vulnerabilities What are the actions and measures to ensure the necessary infrastructure? How can we make communities more resilient?
What are the opportunities for development? What are the conditions for settlements to be less depending on external elements?
Informal settlements, as well as all forms of slums covered in the study, present different degrees of vulnerability. In most cases, these are structural vulnerabilities, for instance, interrelated and interdependent difficulties. It establishes a relationship where a specific vulnerability of the community is generated by another, which is generated by another, so on. Thus, the first step is to establish strategies
74
that reduce vulnerability. Now that alone is not enough for a sustainable proposal. It is necessary to develop opportunity strategies that bring development, economic, cultural and educational growth to the community. These opportunities are the key for the community to prosper in the future, sustainable practices that enable society to live together, as well as future development.
07 | Design strategies | 2020
bottom-up
top-down What needs to be provided, in terms of infrastructure, planning, policy and investments?
What can be done, independently and in partnerships to allow agility to the process and increase the community resilience?
The first strategy is called “Bottom-up�. In general, the concepts of Top-down and Bottom-up are well known. They represent management methodologies where priority is given to what needs to be defined, planned and programmed by the whole and what can be done in practical actions by those involved. Thus, the strategy is based on identifying measures that: Can be made feasible on the
political and regulatory scale as a basis, and practical steps that can be taken by the community. What we can observe in the application of this methodology are many possibilities for actions that can be taken by settlement residents. These actions increase resilience while shortening deadlines and making the community less dependent on State actions only.

7.3 STRATEGY 2: Adaptable typologies
As one of the main elements of the Bottom-up strategy, there is the production of the urban proposal itself. This example, from the Early Childhood Development and Family Center, proposed by Asa, is a significant element. The main element of the project and initiative is the training of residents and the community in general for the production of construction. In this way, the investment in the housing
80
produiction could serve for the technical improvement of the residents, instead of being explored by a private developers. In addition to development, this concept also reduces costs and enables a political collaboration program with different stakeholders. This collaboration can take place as the training of the workforce of the local community while also creating jobs and social dynamics.

07 | Design strategies | 2020
As a second and essential stage of the Bottom-up Approach is the implementation of residential types. This project concept can be well seen in Elemental’s Villa Verde Housing project, proposed in Chile. In this concept, the project module has an initial consolidated base, establishing a secondary autonomy for the resident to expand the house when necessary. In practical terms, this also means that
Source: Villa Verde Housing, Chile - http://www.elementalchile.cl, 2020
the resident is free to plan the expansion of the residence according to the need. From a cultural point of view, in addition to enabling the stylization of the house, this design party also allows more than one family group to live together. And from an economic point of view, it also has an advantage since the maintenance costs of an entire unit can be much higher than that of a typology tailored to the need.

7.4 STRATEGY 3: Clustering and grid organization
Different traditional African village settlements clusters
Clustering houses in a courtyard format can be considered traditional in Europe and elsewhere in the global north. But in the global south, the urban form follows a much more dynamic logic. However, when looking at traditional African villages, we have the presence of substantial elements of social integration, such as clustered units. In the historical study by Alvin Urquhart, several
88
traditional African villages and communities already preserved their organizational form of courtyard space. These spaces were usually marked by a tree in the centre, where stories are told from generation to generation. Other elements of social interaction are also found in these shared spaces, is an extension of the units and a platform for social integration and cooperation.
07 | Design strategies | 2020
Gambwe settlement village near Pocolo
One of the elements that presents one of the main challenges concerns the high population density of the Vistarus site. In this way, part of the families that today live in the region will need to be integrated into the proposed urban project, another on the site itself or in a second phase of the program. In this way, the separation and breaking of ties of friendships can be minimized with the clustered units
Source: Urquhart, Alvin W., Patterns of Settlement and Subsistence in Southwestern Angola, 1963
strategy. With typologies that encourage coexistence and harmony between families, it can be confirmed that the social impacts of the adequacy of the urban proposal can be reversed. With a design element that combines adaptable typologies with design elements such as clustered units, this strategy aims at social integration and better interaction between different members of the community.
89
Clustered units Typology 1
Clustering the units into group models that can be developed accordingly to the strategies 1 allow a more efficient urban plan to generate social engagement, trust and livelihood to the families. Each housing typology has its own clustering method that leads to a diversity of private and semi-private spaces. The typology four is designed to increase density and allows student accommodation for the university.

By gathering all the blocks into this organization, establishing a matrix that allows both spatial plannings for the blocks and also inner public spaces. The clustering of house groups into a more extensive urban block frameset is n principal measure of design strategy to promote inclusiveness and link among the households.
95
7.5 STRATEGY 4 - The plan development
With the first three strategies defined, the next step in the development of the proposal was the application of the strategy on the site. Thus, the first step was an in-depth study of current connections and circulations, as discussed in the analysis chapter. The site already has a system of connections and flows that works, having as primary means of connection, the avenue to
the south of the site. Following the same line of analysis, two existing circulation axes within the site also stood out. Thus, the work took place in overlapping these two existing circulation axes, which led to the system of dividing the site into different sectors. These sectors can be used in the implementation phase as a phasing strategy, and also as points of organization of the masterplan. With these
aspects defined, a new street network was proposed, which will follow the existing logic but more efficiently. And finally, strategies 1, 2 and 3 were applied to the organization of the masterplan, to compose the systems. Several mass studies of block layout have been developed to arrive at the current system. Following is this step-by-step strategy
1. The very frist step to the design proposal was to identify the current urban form of the shacks. 96
07 | Design strategies | 2020

Masterplan organization
The proposal is organized in the urban grid frame previously proposed, with the leading urban network organized from the central urban park that connects the site with its surroundings. The connection increases the level of social security and rescues important values of connection between the community and the city.

Housing typologies
The set of proposed typologies are organized in order to provide an urban set that can be transformed over time, according to the needs of the community. Residential types can accommodate more than 600 families, with the added possibility of mixed residential and commercial use, as well as student housing for the university.

Economic opportunities
For the community to be able to strive sustainably in the future, investment in training is essential, but also in ways to generate profit. Thus, a set of different uses has been established, which can be a source of monetization for the community.

Climate Opportunities - Rain
As one of the main points highlighted by the research is concerning water, a system for capture and reuse was proposed. The system foresees a set of street canals that, at first, retain rainwater and make natural filtration for use as cleaning and irrigation. The city has a significant rainfall, especially in winter, which is a factor that we can take advantage of.

concluding remarks
The in-depth study of urban development conditions in the most vulnerable regions of Africa, as well as the development of an understanding of the specific conditions of South Africa, led to an essential contribution to the detailing of the urban proposal.
what I identify as the great outcome of this master’s thesis: the transformative power of collaboration. A collaborative work platform, exchange of knowledge, experience and ideas is the key to elucidating the urban proposal, called Rolihlahla Village.
The study trip to Nelson Mandela Bay, as well as Port Elizabeth, had a significant influence on
Rolihlahla is a term that has its meaning traced as “troublemaker�, but it is mainly known in South Africa and the
world by the one who carried the name: Nelson Rolihlahla Mandela. As well as the essential struggles traced in the history of the South African people, the courage and collaboration needed to transform the future are present in society, which continues to fight for the best future of the nation. The small contribution to the urban prospect of this work aims at the same, essential values.

The word Rolihlahla is a very special word for South Africans. Although not well known around the world, the etymology of the word has a special meaning, which if placed in its historical context, makes perfect sense. This was Mr Nelson Mandela’s birth name: Nelson Rolihlahla Mandela.

Historically, as one of the leading historical figures in the fight for freedom, equality and an end to racism, Mandela dreamed of a world where people were celebrated not for the colour of their skin but for the content of their minds.

It is an isiXhosa name, and its meaning can be directly translate to “pulling the branch of a tree”. However, colloquially it
The Rolihlahla Village is a project proposal that is based on the vision of equality and respect for communities.
It is essential to clarify that the plan does not intend to solve the structural problem of inequality in Africa and the

world, but rather to guarantee conditions for a prosperous and dignified life, factors that cannot be denied to anyone. The world is changing rapidly, as are our cities, and it is fundamental for sustainable urban designers, to ensure that our decisions and project consequences will include everyone. In the future, there will be no place for inequality any longer.
