Vulnerabilidade socioambiental em bacias hidrográficas no Setor Leste Metropolitano de Fortaleza, Ceará.

When considering the geotecnology innovations come enhancing new studies in contemporary times, It notes that the geoinformation of precepts have an effective application in addressing watershed. Thus, the study aims to map the socio-environmental vulnerability in coastal watersheds of rivers Catú, Cabure, Caponga Funda, Caponga Roseira and Mal Cozinhado, located in the eastern sector of the metropolitan area of Fortaleza, state of Ceara. The theoretical-methodological foundation lies in the systemic studies, based on the bias of the indivisible conception of nature and society. The Environmental Vulnerability Index was structured from the integrated analysis of the ecodynamics conditions (Environmental Vulnerability), together with the Socio-Economic Vulnerability (Municipal Human Development Index). The results achieved in this study portray that 82.27% of the area is classified in the low zone or medium-low Environmental Vulnerability and 17.73% are in the medium-high or high vulnerability zone. We conclude that in the area referred is very intense the anthropogenic pressure on environmental systems, with special emphasis on the river, lake and coastal plains. [ABSTRACT FROM AUTHOR]
