The Kinetic City




This scheme was used in the lecture 'The Kinetic City, Designing for Informality in Mumbai' by Rahul Mehrota, when he was professor in urbanism at MIT. In the lecture he uses the term 'the kinetic city', referring to the constant dynamic processes shaping the urban space of Mumbai, the making and remaking of the city, as opposed to the 'static city', the city of concrete and bricks that architects usually work with. Recently Mehrotra was appointed Chair of the Department of Urban Planning and Design at Harvard.

The scheme shows 'The Five Stages of Squatting', as he calls it; the five stages that a Mumbai street vender has to go through to become a more or less established part of the urban domain.

In the first stage the new street vender stalls out the products he is selling on some cardboard sheets on the sidewalk. He barely has any products on stock, so that he can never loose much if he were to be attacked by his competiting neighbors. A small number of people get interested in buying the goods he is selling. After a while he obtains a handful of costumers who regularly come back, making it possible for him to move into stage two. The street vender has teamed up with his competitors and does no longer have to fear being pushed away at any time. He can invest the money he earned to have more products on stock. But he also drew attention from the police. He now has a carpet to sell his goods, so that he can easily pick up the carpet with all his stuff inside, and run away if the police is signalled by someone on the lookout, and would raid the location where the street vender is selling his goods. To move into stage three, he needs to spend some of his earnings in bribing the police, so that they allow him to stay in place and put a bigger table to stall out his goods on a better display for his costumers. Now the street vender is less flexible, but he is able to bribe the police when necessary and has less to fear from competiting street venders. In stage four he expands his business and by offering more products and appeal to a wider range of costumers. By now he is a well-known street vender, but he needs prepare himself for the rain as monsoon is approaching. Therefore, in the final stage the street vender builds a small shed and is now an established part of the urban fabric.

It's a very interesting way of addressing this process and demonstrating that there is actually a pattern behind this process of informality.

In this post I will indicate a major trend in the development of favelas in Rio de Janeiro: how favelas ever more emerge in the outskirts of the city. I will also briefly discuss the governmental response over the past decade, and the practical impact of the City Statute (Estatuto da Cidade) in Rio de Janeiro.

A major shift, in more than 120 years since the first favelas emerged in Rio de Janeiro, is their location. Favelas initially sprang up on the hillside in proximity of the city centre, later, during the 1930s to 70s, in the proximity of factories, and after that on marginal spaces, such as the spaces between infrastructure elements.

Slum communities today are increasingly appearing in the far suburban regions, such as Barra da Tijuca and Santa Cruz. Teresa de Almeida Faria, in her doctoral dissertation at the planning institute of UFRJ, states that urban poverty moves to the edges of the city, ‘far from the city centre, from work, and from collective facilities and services’. Here the residents expect to find better social and economic conditions than in the central favelas. The poor do not only move to communities on the edges of the city, but also to regular popular neighborhoods, where they are able to buy their own property with legal entitlement. De Almeida Faria calls this process ‘peripherization’, and partly relates this back to the theory of John Turner, who saw ‘autoconstruction as a solution for urban poverty’ (de Almeida Faria 2004, pp. 22-5). It would be a positive development if poor favela residents have the opportunity to move to better and safer neighborhoods outside the city centre, albeit legal or illegal, but it requires investments in these peripheral neighborhoods from the local government, as residents of these peripheries still contribute largely to the flourishing of the city centre by working there.

We can state that the appearance of new favela locations has followed a parallel development as formal city planning. This is a consequence of the proximity to work. Janice Perlman enhances the position that new favelas today are continuously constructed in the proximity of service and construction jobs in more affluent areas (Perlman in: Roy & AlSayyad 2004, p. 109). Today these areas are not only concentrated in the city centre, or near factories, but ever more found in the peripheries. The proximity to individual economic opportunities is a more important motive to move than the proximity to urban services, schools, or an improved quality of life. It is not a coincidence that we observe the largest increase in community residents near Barra da Tijuca, the city’s major expansion area. In this area there is a great demand for laborers and work force, ranging from construction to domestic work.

Communities in the West Zone show the strongest growth rates today. The expansion of the existing communities - particularly in Zona Sul - often does not manifest itself through more land occupation. Rather we can observe vertical growth. People sell their roof rights to friends or family, permitting them to construct another one or two floors on top of their house (Neuwirth 2006, p. 56). Often the houses are prepared for this, steel bars of the reinforced concrete stick out at the top of the columns to allow vertical expansion. In favelas such as Rocinha many buildings are at least six floors tall. As these buildings are often improperly constructed of low cost materials, this leads to hazardous conditions. The road networks and urban services have insufficient capacity for the increasing density of inhabitants.

Despite all efforts in the past two decades, the number of favelas and community residents is still increasing today. Besides their political backgrounds, the legal status of slum communities seems to be a political instrument. As an example I will briefly discuss the community of Nova Cidade, in the lower class neighborhood Inhoaíba in the West Zone.



Nova Cidade

Nova Cidade is in terms of land occupation the second largest favela of the city. The community is indicated on the 2008 census map of favelas by the municipality of Rio de Janeiro, but was not yet indicated on the map of the 2005 census. Using dated photos from Google Earth it is clear to see that the neighborhood already existed in 2005; it has, in fact, barely changed nor expanded since 2005. The only thing that changed was its legal status. How this neighborhood emerged as a ‘new' favela is unclear. Further research needs to be performed on whether this kind of numerical increase of favelas is informal, and unplanned. 

 Nova Cidade 2005
 Nova Cidade 2010

















 I can only suggest some possible explanations for this case, assuming that the houses have been constructed without legal entitlement on land owned by the municipality:

- The municipality indicated the community as favela, so that it can invest in improvements of the neighborhood and implement a project such as Favela- Bairro or PAC (which seems to be not the case at this moment);

- The municipality has plans to use, sell, or exploit the land, and needs to relocate the residents currently occupying the land;

- Increasing violence or circumstances have raised awareness and interest in this community;

Either way, the condition in which the legal status of a neighborhood can change, without the neighborhood changing, raises concerns. The level of urbanization seems to stand separate from this characterization, as adjacent houses, just outside of this area, are constructed along an unpaved street, while all the streets in Nova Cidade are paved.

Hernando de Soto describes the complications of legal property rights in developing and development countries. He uses examples from Haïti and Peru, and also refers to Brazil. De Soto states that once property rights are obtained through formal, legal means (which is often a process of years, if not decades), it is often as difficult to sustain the legal status of the property rights as it was to obtain them (Soto 2000, p. 29). This appears to be the case in Nova Cidade.



The City Statute

One instrument has become very important for the eradication of poverty in Rio's favelas: the City Statute (Estatuto da Cidade), a national policy implemented in 2001.

James Holston describes in four points what the value of the City Statute is, emphasizing the unique status of the City Statute not only for Brazil but worldwide (the italics are added to extract the key points): ‘First, [the City Statute] defines the social function of the city and of urban property in terms of a set of guidelines that are substantive in nature. Second, on that basis, it frames its directives from the perspective of the poor, the majority of urban residents, and creates mechanisms to redress some of the most evident patterns of illegality, inequality, and degradation in the production of urban space. Thus it establishes social equality as a principal objective of urban planning and turns planning into an instrument for social equatization and justice. Third, the statute requires that local master plans and policies be developed and implemented with active popular collaboration. Fourth, it is not framed as a total plan (as in the paradigm of Brasília) but instead as a series of innovative legal instruments that allow local administrations to realize and enforce social function.’ (Holston 2008, p. 292). This fourth point is also addressed by Evaniza Rodrigues and Benito Barbosa who refer to this approach as ‘piecemeal’ interventions (Rodrigues and Barbosa in Cities Alliance 2010, p. 29), a term derived from Karl Popper’s idea of ‘piecemeal engineering’. In this idea, which is one of the key arguments in Popper’s book ‘The Open Society and its Enemies’, social engineering (and I think we can in this case extend this to city planning) is not used as an utopian goal but as a problem-solving instrument. This is a fundamental change from earlier perceptions of city planning in Brazil.

The City Statute is characterized by a strong emphasis on housing. One of the main problems that was tried to bridge with the implementation of the City Statute, was the condition in which private owners of land, often speculating on the increase of the land value, were able to make a stronger claim on the use of public facilities than people who could not afford to legally own land. The City Statute is used to create a more equal balance in land distribution, and in the distribution of urban facilities. This is achieved by departing at the level of the federal government. Whereas earlier the creation of social housing was an issue on municipal level, this responsibility was now shifted back in the hands of the federal government. This shift has resulted in policies such as ‘Minha Casa, Minha Vida' and PAC (Programa de Acelaração do Crescimento, Accelerated Growth Program).

The City Statute in Brazil has provided favela residents with legal means to entitlement of the land where they live after five years of occupation. This does not automatically expell the indication ‘favela’ after five years. There are still possibilities to remove the favelas, but in this case the residents can make a stronger claim on the value of their house, and have a stronger position in the legal issues and plans, and relocation. I will illustrate this with the example of the community Vila das Torres in Madureira.



Vila das Torres

Vila das Torres favela was constructed in the 1960s in the neighborhood of Madureira, on a long strip of undefined land between the transmission lines and the railroad. The community exists of one long street, with houses on both sides. It is approximately four kilometers long and forty meters in width, enclosed between a railroad and a right of way for the high voltage transmission lines. The municipality has proposed a plan for a park on the adjacent area of the transmission lines, Parque Madureira, making relocation of the community residents necessary. The community residents have been offered three possibilities: partly sponsored relocation to regular houses in the neighborhood (R$ 10.000,- + 20% funding for the new house), relocation to a new building sites in proximity of the park with temporary housing during construction works (part of the Minha Casa, Minha Vida program), or a sum of money for their house of R$ 10.000. The latter option is discouraged by the municipality as it is neither in the interest of the residents, nor that of the municipality, for they would loose sight of the residents and their new living conditions. The City Statute and its offsprings, such as Minha Casa, Minha Vida, offers the community residents these opportunities. A condition like this, in which the residents are offered three choices, was unlikely before the implementation of the City Statute.

Vila das Torres in January 2010



Conclusion

I believe that the City Statute is a successful instrument for residents of slum communities, as the social value of their property is recognized. The Statute offers a legal instrument for residents to more appropriate housing. It stood at the basis for several programs in the interest of the urban poor. The availability of nationally financed programs, such as PAC, will stimulate municipalities to search for innovative solutions for slum communities in cooperation with private parties. But the problems are far from solved. With the city in the spotlights of the world press, at least until 2016, Rio still has a long way to go. It must not limit its scope to large projects in the established central areas, but also recognise the increasing metropolitan problems in peripheral zones, and use the City Statute as an instrument to invest in those peripheral zones.

Slum Upgrading in Rio de Janeiro: Favela-Bairro

A pioneering project in slum-upgrading is Favela-Bairro (slum to neighborhood) in Rio de Janeiro. It has contributed to the mindset of urban planning as a participatory process. Largely attributing to its success were a committed local government, that was highly flexible to change existing regulations, and the involvement of grassroots initiators in the design process.

Favela-Bairro, initiated in 1993 and funded in by the Inter-American Development Bank, has reached a total of 147 neighborhoods to date. It was complemented by programs such as Bairinho, and Grandes Favelas, respectively aiming at small-scale and large-scale slums.



One of the key-figures of Favela-Bairro was architect Sérgio Magalhães. He described the main goals of Favela-Bairro as follows (Conde and Magalhães 2004): ‘Integration of slums into the city’, ‘strengthening the (existing) spatial relationship with the city’ and ‘adding new formal and symbolic ones’, as well as providing for ‘essential basic facilities and sanitation’ and infrastructure.

Concretely this was translated to the following design aspects:
• creating interconnections with surrounding neighborhoods;
• building new accesses and expanding the connection with the regular neighborhood public services;
• focussing on pedestrian flows, rather than roads for cars;
• clearly defining public spaces;

An important architectural consideration was that: ‘streets, squares, day care
centers, and buildings were designed according to contemporary trends, without resorting to a ‘simpler’ communication language, without simplistic semantics.’ (Conde and Magalhães 2004, p. 15). This consideration adds a layer of quality to the communities, equivalent to the qualities of the formal city. To architecturally treat the favela in the same way as a neighborhood, with the same means, is seen as the best way toward architectural integration in the city. Magalhães calls this: ‘tearing down material and symbolic barriers between slum and neighborhood’ (p. 15). These qualities in combination with thorough neighborhood analyses, problem-solving programs, the successful designs of Rio-based architect Jorge Mario Jaregui, among others, and grassroots participation have turned Favela-Bairro in a celebrated project.



Three UCL Bartlett scholars (Riley, Fiori, and Ramirez) praise the urbanism and architectural qualities of the project, but are critical about the project regarding its success in contributing to solving poverty: ‘Favela-Bairro will doubtlessly lead to real improvements in the lives of favela residents, giving them access to a wider range of services and infrastructure than ever before, yet as it currently stands, the program does not fulfill its potential to act as a catalyst for broader processes of democratization which are essential to ensure long-term and substantive poverty reduction.’ (Riley, Fiori, and Ramirez 2001, p. 531). If the stigma is purely geographical and based on community resident, rather than other discriminations - as acclaimed by anthropologists Brodwyn Fischer and Janice Perlman - we can not conclude otherwise than that successful urban integration of slums in the urban domain would lead to social opportunities, such as employment. However, the economical and social backgrounds, such as economic inequality on a broader scale, will not solely be solved with an urban design but require a broad effort within society.

Ananya Roy’s warning for the ‘aestheticization of poverty’ - the romantization or enchantment of the vernacular - has to be taken into account: ‘While the aestheticization of poverty can be seen as an attempt to return dignity to the urban poor, it must also be seen as a geopolitical enterprise that ignores the terribly difficult conditions under which the poor struggle and survive and aspire.’ (Roy in: Roy and AlSayyad 2008, p. 303). I think aspiration offers a prospect for the integration of the urban poor, not only in urbanization, but also in city planning. Aspiration is not limited to urbanization, but also requires a form of representation for these facilities. When Ananya Roy speaks about the aestheticization of poverty, she means the romantization of primitive ideas, such as the water-well as a place for social gathering (she refers to a housing project in India), while houses are built without their own water pipes. I think the aestheticization of poverty should be replaced by an aestheticization of urbanity. The facilities of the city must have a representation that is a celebration of urbanity, for which Favela-Bairro is a good, but modest, example. Particularly because, as chief architect Sérgio Magalhães emphasizes, the project does not resort to simple means of representation.

Favela-Bairro is a successful project in its attempt to urbanize slums, and to give this urbanization a representation. But, to place a critical remark: I think it lacks the ambition of integration into city planning at a larger level. The project is restricted to the community itself, and provides qualitative facilities for the community. Despite the emphasis on infrastructure connections, I think this may conceal, particularly for larger slums, a threat that would disconnect them from the surrounding city, by making the neighborhoods independent, that would turn the larger slums into autonomous neighborhoods. One must look for representations with larger, city-wide significance too.

Otto Koenigsberger’s views on the role of planning institutions

Otto Koenigsberger was trained as an architect in Berlin, and migrated in the early 1930’s to Egypt, where he worked as an archeologist. In 1939 he proceeded his career in India, first as chief architect in Mysore State (today: Karnataka State), after the independence of India in 1948 as federal director of housing in Delhi. In India, Koenigsberger was confronted with the needs of partition refugees in the northern provinces of India. He advised on the construction of the New Towns of Faridabad, Rajpura, Gandhidham, and Sindri. Koenigsberger proposed pre-fabricated housing, but as this plan did not succeed, Koenigsberger resigned and moved to London in 1951. In London, Koenigsberger co-founded the Department of Tropical Architecture at the Architectural Association in 1954, of which he became the head in 1957. In 1970 he established the Development Planning Unit at University College London. From the 1950’s onwards, Koenigsberger served as UN consultant on housing missions in several developing countries, where he worked closely with Charlas Abrams (main sources: Baweja 2008; and DPU-website).

Koenigsberger introduced the paradigm of ‘Action Planning’ in Architectural Association Journal in 1963. This was after he abandoned the idea of top-down planning, after his experiences in India.

Koenigsberger sought for a division of tasks in the provision of mass housing in third world countries. He defined the responsibilities of public sector agencies, such as local governments as: ‘the provision of housing plots, physical infrastructure, housing finance and, where necessary, subsidies. Their role will be to help, but not to control.’ (Koenigsberger 1986: 27). In the 1940’s and 50’s, there was a great demand for housing in the third world. Initially, the method of mass-produced, pre-fabricated housing units was proposed. This could reduce labor costs and consutrction time, and has proven successful in many western countries after the Second World War. However, as labor costs were already low in third world countries, this approach found little success. As a response to mass housing projects, USAID initiated ‘aided self-help’; future residents were responsible for the construction of houses, whereas the public sector provided for land, public services and provided for those parts of the job that required special skills of knowledge. This method was not widely applied, however, its success laid in the fact that it ‘established the principles of the division of labor and collaboration between private and public sectors’ (Koenigsberger 1986: 30), thereby paving the road for ‘sites-and-services’. Sites-and-services differed from aided self-help in a sense that allottees were provided with plots, roads, water, sewege, etc., and were free to construct their own houses. Hence, the investment of public institutions remained low. As the policy was embraced by the World Bank, sites-and-services turned into a successful instrument in the provision of housing in the third world. Koenigsberger, however, criticized sites-and-services, as the many of the projects did not reach the poor, but fell in the hands of middle-class residents, leaving the poor no other option than squatting. Koenigsberger favored slum upgrading, which he described, despite its limited application, as a ‘resounding success’, in particular in reforming our thinking about urbanism for the poor (koenigsberger 1986: 31). Slum upgrading was based on the squatter’s ‘goodwill and managerial gifts’, which it rewarded with security of tenure and basic infrastructure and facilities.

The process of building is a public affair, undertaken by the residents of the squatter settlements, while providers of public services, such as water and sewage, are poorly coordinated, and do not communicate their projects with each other or with planners. In the process of slum upgrading, Koenigsberger sees the need to redefine the role of planners. Koenigsberger advocates that ‘planners must learn to think of themselves not as controllers, but as initiators, and leaders of development’ (Koenigsberger 1983: 52); planners should start by laying out a public sector initiative, providing for plots and facilities, followed by attracting both rich and poor private investors to invest. This requires a role for the planner as an entrepreneur, as a ‘public sector developer’, or ‘development administrator’. He abandons the idea that planning should determine the exact outcome; planning does no longer mean the creation of blue-prints, but rather the initiation and coordination of processes, in which private and public sector initiatives should be brought together. This is brought forward in his most influential article ‘Action Planning’ in the Architectural Association Journal in 1963.
