Este estudo compreende uma avaliação de procedimentos e medidas de recuperação de áreas degradadas por mineração na Região Metropolitana de São Paulo-RMSP. Inicialmente, apresenta-se o problema investigado e a hipótese que orientou a pesquisa. Destaca-se o caráter incipiente dos trabalhos de recuperação efetuados na RMSP e o papel relevante que poderiam ter em face do contexto urbano (Capítulo 1). Descreve-se o método adotado na realização da pesquisa, ressaltando o levantamento de 42 minas ativas (17 de brita, 15 de areia, 4 de caulim, 3 de argila, 1 de calcário, 1 de quartizito e 1 de rocha ornamental), 11 minas desativadas e 54 antigas áreas de mineração atualmente ocupadas por outros usos, totalizando 107 áreas estudadas (Capítulo 2). Apresenta-se um breve panorama mundial e nacional sobre o tema da recuperação de áreas degradadas por mineração. Inclui-se uma discussão sobre conceitos básicos, métodos e técnicas comumente empregados em minas ativas, usos pós-mineração freqüentes e instrumentos legais, institucionais e empresariais utilizados no planejamento e gerenciamento da questão (Capítulo 3). Avaliam-se os procedimentos relacionados ao planejamento da recuperação na RMSP, tendo como referência a análise de 91 Planos de Recuperação de Áreas Degradadas-Prads relativos a minerações ativas e desativadas na RMSP (Capítulo 4). As medidas de recuperação praticadas em minas ativas na RMSP são avaliadas quanto às finalidades desejadas, procedimentos adotados e desempenho obtido (Capítulo 5). Discutem-se aspectos relacionados à instalação de usos pós-mineração na RMSP, tendo como base o estudo em minas desativadas e a análise sobre a reabilitação de antigas áreas de mineração que se encontram atualmente ocupadas de forma desordenada ou planejada (Capítulo 6). Ao final, sintetizam-se as conclusões gerais obtidas, contemplando os aspectos principais sobre as medidas de recuperação e a instalação de usos pós-mineração na RMSP

Historically, the Human Development Index (HDI) is used to measure the socioeconomic performance of a population. Despite harsh criticism about its efficiency as an indicator of development, it is still widely used as a tool for public management planning. This study proposes a methodology using geoprocessing techniques to perform the mapping and prediction of HDI spatial distribution in the Una River Basin (HDI URB). We used data from the 2010 Demographic Census to calculate the sub-indexes of population longevity, education and income. After obtaining the results, we applied Ordinary Kriging geostatistical interpolation to obtain the continuous variation of HDI values. According to the results, the highest value of HDI URB was obtained in the northern region of the basin located near the urban area of the municipality of Ibiúna (0.86), decreasing as it approached the southern region (0.69), classified as an average human development. Finally, the methodology, despite some limitations, proved to be satisfactory, since it was able to represent internal differences in a water basin from the point of view of quality of life of the population. It may be applied as a tool for management and public administration.

Purpose – The purpose of this paper is to investigate the effectiveness of mitigation measures adopted in a scheme of EIA follow-up by examining their performance in reducing geo-environmental impacts in earthwork activities during the Rodoanel southern section construction in São Paulo, Brazil. This environment is fragile in terms of affected watersheds because the highway crosses two important reservoirs that supply most of the metropolitan water demand. Therefore, this research also aims at promoting water quality control. Design/methodology/approach – This study combines complementary sources as evidences in the literature and field checks, tests and monitoring. The methodology was supported by criteria for evaluating the effectiveness of mitigation measures in the case study approach. Findings – The EIA follow-up activities contributed to the maintenance of environmental conditions in the majority of the control points at the end of the construction phase. Water quality parameters were not statistically different before and during the construction of the highway. The choice and arrangement of mitigation measures were successful in ensuring water quality control by avoiding siltation. Practical implications – A robust scheme for designing and evaluating mitigation measures contributes to the improvement of their effectiveness and is pivotal to the success of the EIA follow-up. Originality/value – This case study serves as an example for extending EIA follow-up practice in special to the improvement of the design and evaluation of mitigation measures in similar contexts.
