ABSTRACT

Background: Homicide rates in Brazil are among the highest worldwide. Although not exclusive to large Brazilian cities, homicides find their most important determinants in cities' slums. In the last decade, an urban renewal process has been initiated in the city of Belo Horizonte, in Brazil. Named Vila Viva project, it includes structuring urban interventions such as urban renewal, social development actions and land regularization in the slums of the city. This study evaluates the project's effect on homicide rates according to time and interventions. Methods: Homicide rates were analyzed comparing five slums with interventions (S1⁻S5) to five grouped non-intervened slums (S0), with similar socioeconomic characteristics from 2002 to 2012. Poisson regression model estimates the effect of time of observation and the effect of time of exposure (in years) to a completed intervention, besides the overall risk ratio (RR). Results: Using the time of observation in years, homicide rates decreased in the studied period and even more if considered cumulative time of exposure to a completed intervention for S1, S2, S3 and S4, but not for S5. Conclusions: Although the results of the effect of the interventions are not repeated in all slums, a downward trend in homicide rates has been found, which is connected to the interventions. New approaches could be necessary in order to verify the nexus between slum renewal projects and the reduction of homicide rates.

ABSTRACT

There is little scientific evidence that urban upgrading helps improve health or reduce inequities. This article presents the design for the BH-Viva Project, a "quasi-experimental", multiphase, mixed-methods study with quantitative and qualitative components, proposing an analytical model for monitoring the effects that interventions in the urban environment can have on residents' health in slums in Belo Horizonte, Minas Gerais State, Brazil. A preliminary analysis revealed intra-urban differences in age-specific mortality when comparing areas with and without interventions; the mortality rate from 2002 to 2012 was stable in the "formal city", increased in slums without interventions, and decreased in slums with interventions. BH-Viva represents an effort at advancing methodological issues, providing learning and theoretical backing for urban health research and research methods, allowing their application and extension to other urban contexts.

Resumen Hay poca evidencia científica de que las estrategias de regeneración urbana contribuyen a mejorar la salud y reducir las inequidades. En este trabajo se presenta el diseño del Proyecto BH-Viva, estudio “cuasi-experimental”, de múltiples fases, con métodos mixtos, incluidos los componentes cuantitativos y cualitativos, que propone un modelo de análisis para el seguimiento de los efectos de las intervenciones en el entorno urbano puede tener en la salud residentes de las aldeas y los barrios marginales en Belo Horizonte, Minas Gerais, Brasil. En el análisis preliminar hubo diferencias intra-urbanas en la mortalidad proporcional por grupos de edad, al comparar las zonas con y sin la intervención; las tendencias de la mortalidad de 2002 hasta 2012 se mantuvieron estables en la ciudad formal, el aumento en el pueblo sin ninguna intervención y disminuyen de que con la intervención. El BH-Viva es un esfuerzo para avanzar en cuestiones metodológicas, proporcionando el aprendizaje y la base teórica de los métodos de investigación y de investigación en salud urbana, lo que permite la aplicación y la extensión en otros contextos urbanos.


Resumo Há poucas evidências científicas de que estratégias de requalificação urbana contribuam para a melhoria da saúde e redução das iniquidades. Este artigo apresenta o delineamento do Projeto BH-Viva – estudo “quasi-experimental”, multifásico, com métodos mistos, incluindo componentes quantitativos e qualitativos, propondo um modelo de análise para monitoramento dos efeitos que intervenções no ambiente urbano possam ter sobre a saúde de moradores de vilas e favelas em Belo Horizonte, Minas Gerais, Brasil. Em análise preliminar observou-se diferenças intraurbanas na mortalidade proporcional por grupos etários, ao comparar áreas com e sem intervenção; a tendência de mortalidade de 2002 a 2012 mostrou estabilidade na cidade formal, aumento na vila sem intervenção e decréscimo naquela com intervenção. BH-Viva representa um esforço no avanço de questões metodológicas, fornecendo aprendizado e subsídios teóricos para a pesquisa e métodos de investigação em Saúde Urbana, possibilitando a aplicação e extensão em outros contextos urbanos.

ABSTRACT

Mitigation policy and regulatory frameworks are consistent in their strong support for the mitigation hierarchy of: (1) avoiding impacts, (2) minimizing impacts, and then (3) offsetting/compensating for residual impacts. While mitigation frameworks require developers to avoid, minimize and restore biodiversity on-site before considering an offset for residual impacts, there is a lack of quantitative guidance for this decision-making process. What are the criteria for requiring impacts be avoided altogether? Here we examine how conservation planning can guide the application of the mitigation hierarchy to address this issue. In support of the Colombian government's aim to improve siting and mitigation practices for planned development, we examined five pilot projects in landscapes expected to experience significant increases in mining, petroleum and/or infrastructure development. By blending landscape-level conservation planning with application of the mitigation hierarchy, we can proactively identify where proposed development and conservation priorities would be in conflict and where impacts should be avoided. The approach we outline here has been adopted by the Colombian Ministry of Environment and Sustainable Development to guide licensing decisions, avoid piecemeal licensing, and promote mitigation decisions that maintain landscape condition.

ABSTRACT

The Brazilian state of Mato Grosso was a global deforestation hotspot in the early 2000s. Deforested land is used predominantly to produce meat for distal consumption either through cattle ranching or soya bean for livestock feed. Deforestation declined dramatically in the latter part of the decade through a combination of market forces, policies, enforcement and improved monitoring. This study assesses how representative the national-level drivers underlying Mato Grosso's export-oriented deforestation are in other tropical forest countries based on agricultural exports, commercial agriculture and urbanization. We also assess how pervasive the governance and technical monitoring capacity that enabled Mato Grosso's decline in deforestation is in other countries. We find that between 41 and 54 per cent of 2000-2005 deforestation in tropical forest countries (other than Brazil) occurred in countries with drivers similar to Brazil. Very few countries had national-level governance and capacity similar to Brazil. Results suggest that the ecological, hydrological and social consequences of land-use change for export-oriented agriculture as discussed in this Theme Issue were applicable in about one-third of all tropical forest countries in 2000-2005. However, the feasibility of replicating Mato Grosso's success with controlling deforestation is more limited. Production landscapes to support distal consumption similar to Mato Grosso are likely to become more prevalent and are unlikely to follow a land-use transition model with increasing forest cover.

ABSTRACT

Advocates of land-titling programs in developing countries posit that these programs lead to a multitude of benefits, including health improvements. This paper presents the results of a child health survey of several Lima communities after various time exposures to Peru's urban land-titling program. The results provide suggestive evidence that improved property rights increase children's weight but not their height, which is consistent with previous work on the topic. However, titles also appear to raise children's risk of being overweight or obese, implying that the observed weight gain is not necessarily an improvement in nutritional status.
