Today municipalities and international agencies use new forms of urban upgrading as tools to address both the traditional structural problems of poverty and also as tools for violence prevention. While a causation between informal spaces and insecurity clearly does not exist, there is an interest in understanding the influence of physical interventions in neighborhood security behavior. This research tests ways in which urban projects alter perceptions of security among favela dwellers over time, in the Rio de Janeiro ＂Favela-Bairro＂ urban upgrading project. Finds that while security conditions are marginally affected, location close to main roads part of the urban upgrading project affect residents＇ security perceptions positively. However, individuals in less accessible areas of the favela present less openness to address security questions. It argues that individual proximity to upgraded main roads experience shelter from the effects of retaliation from perverse actors than those that have their accessibility impeded. Other projects such as public spaces or buildings show no significative changes in security perceptions.展开更多

This paper presents a methodology developed using shape grammar to analyze the informal city, specifically Favela da Rocinha’s buildings, in Rio de Janeiro. The goal was finding the organizational foundations of self-built houses in an informal settlement. A methodology was developed to find composition patterns and to infer a set of rules which defines a shape grammar of Rocinha houses, allowing synthesis and analysis of low cost solutions for house designs. And above all, it highlights underlying design solutions produced empirically by inhabitants of favelas, emphasizing the diversity in favela’s architecture, and, that is also able to reflect the particular necessities of targeted population.展开更多
