Résumé
The impacts of climate change vary across regions and communities. In general, these are most severe in those regions which display high vulnerability on account of a number of factors including social and climatic vulnerabilities. Droughts and desertification contribute to reducing the availability of water, which increasing impacts agriculture and probably reduces the quality of life of populations in semi-arid region. This work presents an evaluation of social and environmental vulnerabilities in six semi-arid districts of Bahia, Brazil. The methodology was developed from the assessment of scenarios from the Intergovernmental Panel on Climate Change (IPCC) and forecasts of the Instituto Nacional de Pesquisas Espaciais (INPE) for regions of Brazil. The aim was to identify climatic, socioeconomic and environmental indicators in seeking to assess the social vulnerabilities in the districts studied. Subsequently, an index of socio and environmental vulnerabilities for municipalities was studied, and as a result, it was possible to identify which municipalities have greater social vulnerability in the face of climate change estimates for the semi-arid region of Bahia - Brazil.
