Planejamento Urbano

This paper explores the housing challenges that Rio de Janeiro faces, which is specifically manifested in the form of favelas or squatter settlements, and that municipality’s strategies to overcome these challenges. The Favela Bairro slum upgrading program (FBP), which seeks to transform favelas into formal neighbourhoods, is seen as a complex and appropriate solution to Rio’s housing woes. The paper specifically focuses on land tenure challenges in Rio and the way the FBP dealt with this issue. The FBP is noteworthy as an example of slum upgrading without full land tenure legalization and for its use of state of exception, primarily the concession of right to use but not full ownership of land in order to allow this program to take place. This placed greater emphasis on infrastructural and living condition improvement rather than legalization of land tenure. As a result, the implementation of FBP has had the effect of increasing the security of tenure of favela residents.

Over the past decade there has been a sudden, extraordinarily large, and simultaneous expansion of multi-billion dollar housing programs in many emerging and developing economies. This shift occurred after a long period of limited public involvement in social housing production. Yet, despite the fact that countries and cities have introduced such large-scale programs, there has been little independent analysis of the rationale, efficacy and potential long-term effects of these interventions. Adopting a perspective that expands beyond typical public finance approaches, this paper examines the renewed shift in public housing provision. It provides an outlook of recent experiences in housing provision, showcases general trends in housing, proposes an evaluation framework, and offers a series of recommendations aiming at strengthening the programs. The paper concludes that if large-scale housing assistance is to help accommodate the almost 2 billion additional people who will live in cities over the next 35 years, as well as help to address the growing housing affordability issues, much more attention should be paid to the lasting effects that such programs can have on the structure of cities for generations to come.

Recently a large data set has been collected for LAC countries, which permits detailed study of household tenure. This data set constitutes the empirical basis of this paper in which the following research questions are addressed: What are the main patterns of urban housing tenure in LAC countries and how and why do they differ? What is the role of household income in determining urban housing tenure? To what extent does the presence of informal housing upset the positive linear relationship between income and tenure that is typically found in developed countries? The paper is organised as follows. The first section offers a brief review of the existing literature on the role of household income and tenure. The methodology employed in the study is explained in the second section and the results are presented in the third section.

Urban inequality is widely debated but few studies examine developments over time and across cities. In this contribution, we develop a novel approach to study the dynamics of inequality in cities of the Global South. Using a sample that includes cities in Africa, Latin America, and Asia, we track trends in equality since the 1990s in four domains: the labor market, education, private goods, and public amenities. With descriptive statistics, inequality indexes, and logistic regression analysis, we show that while inequality in educational attainment is decreasing across all cities in our sample, patterns in the other domains are more complex. Even though the middle occupational group is growing in most cities in our sample, there are important exceptions and substantial regional variations. While we find that inequality in material comfort more often decreased than increased, class position continues to predict access to both private goods and public amenities. Although the observed patterns are complex, we find no proof of escalating inequalities in the domains under study.

What can the Participatory Budget (PB) teach us about slum upgrading in the cities of the Global South? This article describes the process of slum upgrading via PB in Porto Alegre, Brazil. Participatory budgeting (PB) is a renowned mechanism of resource allocation that transfers decision-making power over the capital expenditure portion of the municipal budget from the City Council to public assemblies. However, the impact of PB on municipal service delivery in general and housing in particular is understudied. Ethnographic findings are based on slum upgrading process via PB in an informal settlement in the East District of Porto Alegre. Fieldwork included 16 interviews with residents who had been PB delegates, PB councilors, municipal architects, lawyers, and the social worker involved in the slum upgrading project of Vila Radiante, East District. Furthermore, analysis of district-level expenditures on public works required for slum upgrading as well as analysis of site plans informed the conclusions. The Porto Alegre PB demonstrates that slum dwellers' involvement in all stages of the slum upgrading process, from resource allocation to service delivery, contributed to the effective distribution of housing and basic infrastructure. Slum dwellers are a heterogeneous group with diverse housing needs. Housing via PB addresses this diversity and provides an alternative to the dichotomist debate in international planning between, on one hand, slum clearance followed by public housing projects and, on the other, the promotion of assisted self-help housing through programs of land tenure and basic infrastructure provision.

The main purpose of this paper is to ascertain whether the concession of real right to use (CRRU) has been widely applied by Brazilian municipalities, and the extent to which beneficiaries (individuals living in regularised low-income settlements) make effective use of such an instrument to secure tenure status. Another relevant aspect is to review the relationship between securing land tenure and the use of land as collateral for investment. It is hoped that the paper can be used as the basis for a longitudinal study to monitor progress in the provision of secure tenure for the urban poor in Brazil, by investigating the strengths and weakness of CRRU to the formulation and implementation of pro-poor urban land tenure policies. Findings indicate that municipalities have to overcome problems related to the implementation of these programmes, such as; resistance on the part of the judiciary (at the municipal level) to incorporate newly acquired rights; the need to change attitudes towards the legalisation process of occupied land; and the need to change residents’ perceptions of this new instrument. The success of CRRU can depend on the articulation of these issues, as well as more integrated actions among planners, lawyers, city managers, and the residents of these settlements to advance performance.

The city of São Paulo, home to 11 million people, suffers constantly the effects of  flooding caused by extreme precipitation. Localized floods occur every summer in various parts of the city. Besides the losses and inconvenience felt by the residents, floods produce damages that cross the city boundaries, affecting income and output in the metropolitan area as well as in other parts of the state and the country. The objective of this study is to evaluate the economic impacts of floods in the city of São Paulo through the use of a Spatial Computable General Equilibrium (SCGE) model integrated to GIS information related to the location of points of floods and the firms within their influence. It is estimated that floods contributed to reduce city growth and residents' welfare, as well as hampering local competitiveness in both domestic and international markets. An intra-city total impact-damage ratio of 2.2 and an economywide total impact-damage ratio of 5.0 were found.

The main question concerns the ways in which knowledge management configurations (KM) within urban governance are being transformed through digitization and spatializing information (GIS). This question fits into broader discussions on how knowledge construction, circulation and utilization can improve competences in local government (efficiency and effectiveness), make urban planning more knowledge-based, and provide greater recognition of citizens’ knowledge (accountability). Local governments need such instruments in dealing with increasing complexity and uncertainty in urban development. We examine how uneven patterns of technological change in using ICT and GIS are transforming current local government work processes in terms of efficiency and effectiveness in their outcomes, utilizing empirical data from extended case studies in six medium-sized cities in India, South Africa, Brazil, and Peru, participating in the Chance2Sustain research network. Knowledge management in cities is configured through several dimensions: 1) discourses for digitizing KM in local urban development; 2) actor networks producing socio-spatial knowledge; 3) embedding KM in decision-making processes (power struggles, exclusion); and 4) influences of KM on work practices and interfaces with citizens. The case study results show that 1) KM discourses concerned four issues: strategic urban planning and integrated land use planning; determining geographic boundaries in urban development discourses; streamlining work processes of local governments, and mapping poverty and needs assessments; 2) initiatives mainly link government with the private sector at various scale levels; 3) codified and technical knowledge remains dominant in discussions on urban development; and 4) effects of KM are uneven, but improve work process efficiency, although the interface with citizens remains limited, focusing on middle-class relations to the exclusion of the poor.

International theory and practice have promoted state-assisted upgrading of ‘informal’ urban areas worldwide since the late 1970s, with various forms of monitoring and assessment of impact. Two independent studies of how residents perceive and evaluate such interventions have recently been undertaken for neighbouring parts of the upgraded area of Novos Alagados on the Itapagipe peninsula in the northwestern part of Salvador, Brazil’s third largest city. These studies start from different premises and have been implemented in very different ways, but both have the objective of permitting the ‘voice’ of the residents to be heard concerning the upgrading process. Comparing them helps highlight the essential ‘fuzzy’ nature of values concerning urban interventions of this nature and leaves us with thoughtprovoking questions concerning the role of local society in relation to the state in urban development, and the potential this has for on-going forms of urban management in cities which are emerging globally.

The presence of precarious housing solutions, such as favelas and irregular settlements, is a basic feature of urban inequalities in Southern cities, and the predominant description of the international literature suggests social and housing homogeneity of these areas. They are known to be strongly affected both by economic conjunctures and by public policies, which changed intensely in Brazilian metropolises since the 1990s, transforming the existing housing precarity. This article discusses recent changes in housing precarity in the city of São Paulo, showing a reduction of its intensity, but the increasing heterogeneity of the situations. We estimate the population in favelas and irregular settlements and the socioeconomic indicators of their inhabitants and households recently, drawing on a study using Census data and Geographic information system techniques. The paper shows that nonetheless there was a significant improvement of life conditions in favelas and irregular settlements, which tend to be quite heterogeneous, there is a maintenance of considerable inequalities between these housing solutions and the entire rest of the city.
