This paper presents a study on quality of life and sustainability indicators relating to site-planning parameters for low income public housing projects in the region of Campinas, Brazil. The study is based on a post-occupancy-evaluation (POE), conducted in five housing developments. Most of these housing projects are based on a repetitive model and are devoid of urban infrastructure. Users act on their own in providing for some elements considered necessary to create an identity and community spirit. Results show that the population relates quality of life to economic factors and sustainability is associated to reduce utility bills. Houses are preferred to apartments and satisfaction with the present housing conditions is high, despite low feelings of security in the neighbourhood. This work is part of a broader study, which aims to develop design evaluation tools. Most sensitive quality of life and sustainability indicators related to site-planning should permeate these tools and establish design guidelines. The inclusion of a large number of qualitative design issues into the decision-making process and the questioning of existing standardized solutions are seen as essential means to increase local housing quality.

Experiences of state/community partnerships in the field of land and housing in developing countries have had mixed results in attaining their goals of improving access to shelter for low-income households. Drawing upon evidence from Porto Alegre, Brazil, this paper argues that partnerships may represent an opportunity when the relationship is based on accountability and transparency, on common goals and shared responsibilities, even when resources are scarce. The role of the public partner was to provide technical and organizational assistance and act as a mediator between coops and private interests. The role of the cooperatives was to mobilize as a cooperative and develop a savings and organizational capacity. The partners carried out these roles and developed new ones during the construction of the partnership. The partnership however was not exempt from difficulties. Besides frictions between state officials and cooperators and among types of cooperatives, external constraints jeopardized the development of the organizations. Land use restrictions, lack of access to construction finance and lack of a supportive legislative and policy framework still constitute shortcomings for the development of low-income housing cooperatives in Brazil.

The replacement of fossil fuels by clean energy sources has emerged as a focus for those concerned with the creation of a less polluted urban environment. In this context, Brazil's use of ethanol as a vehicle fuel is unique, especially considering the country's successful adoption of flex-fuel technology first introduced in 2003. Currently, most of the fleet of vehicles circulating in Brazilian cities can use ethanol. The effect of this alternative fuel on the Brazilian urban environment is the focus of this study. In our study, the relationship between Brazil's fleet of flex-fuel vehicles and local CO2 equivalent emissions was investigated using parametric and semiparametric analysis based on modified Environmental Kuznets Curve (EKC) equations. The analyses employed an annual set of state-level panel data for the period from 1998 through 2013. Both analyses show that the Brazilian introduction of flex-fuel vehicles in 2003 contributed to a marginal reduction of passenger car CO2 emissions by 2013. Moreover, results also indicate that (1) there is evidence that flex-fuel vehicles can be a component in the generation of an EKC; and (2) there is a negative relationship between the area under sugarcane cultivation and CO2 emissions due to carbon sequestration. These results indicate that the substitution of ethanol for gasoline through the use of flex-fuel technology leads to fewer total greenhouse gas emissions, considering that greenhouse gas emissions from ethanol combustion and ethanol processing are outweighed by their sequestration during sugarcane growth in rural areas.

Ensuring equal access to opportunities while assessing the housing needs of low-income populations has been a significant challenge in many global south countries. Social housing programs have been recurrently criticized for reinforcing inequalities by ignoring the poor conditions of urban access. This study evaluates the urban access of a national social housing program, My House My Life (Minha Casa Minha Vida, MCMV), in Brazil, one of the most unequal countries in the world. This program is renowned for building many of its housing projects in urban outskirts. We use job accessibility metrics to identify differences and similarities in MCMV housing production in six large Brazilian cities through a comparative lens. We find that although MCMV beneficiaries have less access to job opportunities than average-income citizens, the program may improve their conditions compared to individuals with similar income levels within central cities. We hope that future studies may expand this work to include the surrounding metropolitan areas, which were not considered due to data restrictions. We also expect to encourage other efforts in the investigation of social housing impacts through spatial data science, especially in evaluating accessibility in large-scale social housing programs.

O que é um líder na percepção de um líder? Esta é a questão que a autora enfrenta, utilizando um instrumento psicossocial e psicanalítico em bairros populares de João Pessoa. A partir deste marco teórico de análise é possível perceber que as identidades assinaladas não são similares, mas contrastantes. De fato, as entrevistas realizadas permitem registrar uma clara contradição entre a identidade do líder no espaço individual-familiar e no espaço social-coletivo em que o sujeito se encontra inserido. Por sua vez, esta contradição parece emergir como elemento novo no estudo das relações entre os movimentos sociais e políticas públicas.

The United Nations Conference on Sustainable Development, held in June 2012 in Rio de Janeiro, was probably the largest event in a long series of megasummits on environmental protection and sustainable development. Roughly 44000 participants descended on Rio de Janeiro to take part in ten days of preparatory committee meetings, informal consultations, side events, and the actual conference. Yet despite this unprecedented high attendance by participants from governments and civil society, the outcome of the conference is less than many had hoped for. In this paper I review the outcomes of the 2012 Rio conference in detail, with a special focus on its contributions towards the reform of the institutional framework for sustainable development. Following this review, I discuss the way ahead and options for structural reform to restrengthen earth system governance.

The idea of a group of developing countries with shared characteristics, challenges, and needs, distinct from those of developed countries, has been central to sustainable development discourse and policy for decades. However, in the years since the original Rio conference it has become increasingly apparent that it is difficult to sustain this notion of a single developing world. Within the context of unfolding diversity, a central claim of the present paper is that lumping all countries together under the expansive category of ‘developing’ risks obfuscating the complex challenges, solutions, and fragmented geopolitics of sustainable development. Instead, it is necessary to use the terms developing country, countries, or world far more selectively, mindful that they may conceal just about as much as they reveal. In the paper I proceed to consider a number of alternative national, subnational, and transnational spatial categorisations which might be deployed to better describe and/or analyse the evolving nature, effective governance, and politics of sustainable development challenges across space.
