Análise da degradação ambiental do Polo de Desenvolvimento Agroindustrial do Alto Piranhas utilizando critérios da ecodinâmica da paisagem.

Abstract

The environmental assessment allows the identification of critical areas on the level of degradation is of utmost importance for the development of measures for preservation, conservation and restoration. This study aimed to perform a diagnostic levels of environmental degradation in the landscape between the years 2001 and 2012, adopting the criteria of ecodynamics landscape in the municipalities that comprise the agroindustrial development polo Alto Piranhas. Analyses involving the dynamics of the landscape, environmental, vulnerability, the potential social and economic impacts and degrees. It was found that areas feature predominantly medium stability/vulnerability and moderate vulnerability, potential social and economic medium to moderately low, and environmental sustainability mean in most municipalities. The environmental impacts of high and very high class, especially in areas with agricultural activities, deforestation is present in all municipalities, being proportional to the size of the municipality and the volume of activities. Areas with agriculture increased from (27,2%32,1%), wooded savanna steppe (21,5% - 39,3%) and forested savanna steppe decreased (9,7% - 21,5%). The class irrigated agriculture occupied 5,5% and increased to 6,6% of the area, the consolidated urban area (9,1% - 11,3%) and areas with outcrop (0,4% - 0,2%). Considers the data generated by the survey as propulsion mechanism for the implementation of sustainable development proposal Polo Alto Piranhas, dissemination of data generated by GIS, providing the design and implementation of integrated and coordinated actions
