Sistema de indicadores locais de vulnerabilidade ambiental (SILVA): uma proposta de apoio ao planejamento e a gestão na sub-bacia hidrográfica do Sabugi (PR/RN).

Abstract

The watersheds of the Sabugi located between the states of Paraíba and Rio Grande do Norte plays an important role of the socioeconomic development of the region, performed by agriculture, livestock and other forms of occupation. The watersheds are essential territories for the growth of a region, and it is desirable that they present the best conditions in the soil properties, as well as their use and occupation, in order to maintain the capacity of water coverage for the various activities developed there. The study of environmental vulnerability in hydrographic basin areas becomes indispensable given the importance of diagnosing environmental conditions in mitigating impacts that threaten the dynamics of the ecosystem. In this study, a system of indicators that spatially represented the various levels of vulnerability was proposed: The System of Indicators of Environmental Vulnerability (SILVA). This system covers the following indicators: geology, geomorphology, pedology, climatology and growth, with a scale of variation of 1 to 3, being 1 stable and 3 unstable, as indicated by another adopted option. of the Fuzzy System, with the purpose of assisting in decision making, is an option that allows a hierarchical view of the situations that may exist in the study area. The functions of the human resources management system can be managed in water resource management systems.
