FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico / RESUMO A Ãgua à o insumo bÃsico da sobrevivÃncia de todas as espÃcies e indicador do desenvolvimento de uma regiÃo, sendo necessÃria atenÃÃo especial no seu manejo visando sua conservaÃÃo em qualidade e quantidade. à fato certo que o Nordeste està sujeito a secas periÃdicas. Essas irregularidades climÃticas afetam principalmente as famÃlias pobres das Ãreas atingidas. Devido aos problemas ambientais e sÃcio-econÃmicos causados pelas estiagens que ocorrem no semi-Ãrido, e em particular no Estado do CearÃ, se faz necessÃrio uma caracterizaÃÃo tÃcnico-cientÃfica, atravÃs de indicadores hidrolÃgicos, e sÃcio-econÃmicos, que permitam, ao longo do tempo, um monitoramento permanente e consistente desses desastres naturais. Este trabalho tem como objetivo principal a caracterizaÃÃo dos impactos hidrolÃgicos e sÃcio-econÃmicos na bacia do Alto Jaguaribe . Para a caracterizaÃÃo das secas foram selecionados como indicadores hidrolÃgicos a precipitaÃÃo mÃdia e o Ãndice de aridez, e como indicadores sÃcio-econÃmicos a produÃÃo de grÃos, o PIB e o IDM. Foi proposto a determinaÃÃo de Ãndices experimentais de secas hidrolÃgicas e de secas sÃcio-econÃmicas. A anÃlise desses Ãndices indica uma menor vulnerabilidade sÃcio-econÃmica dos municÃpios em estudo. / Water is the basic input of the survival of all species and indicator of the development of a region which needs special attention in its management aimed at them in quality and quantity. It is indeed true that the Northeast is subject to periodic droughts. These climatic irregularities mainly affect the poor families of the affected areas. Due to environmental problems and socio-economic caused by droughts that have occurred in the semi-arid, and particularly in the state of Ceara, is a necessary technical and scientific characterization, through indicators hydrological and socio-economic, enabling over the time, a continuous and consistent monitoring of these natural disasters. This work has as main goal the characterization of hydrological impacts and socio-economic basin in the High Jaguaribe. For the characterization of drought indicators have been selected as the hydrological and rainfall average index of aridity, and socio-economic indicators such as the production of grain, GDP and IDM. It proposed the establishment of experimental indexes of drought and hydrological drought socioeconomic status. The analysis of these indices indicates a lower socio-economic vulnerability of the municipalities under study.
