Valoração econômica aplicando o método VERA como instrumento de gestão ambiental : caso do riacho Lagartixo no município de Capela - SE

Abstract

The Riacho Lagartixo is located in the municipality of Capela (SE) and plays a fundamental role in the supply and consumption of the municipality, with a drainage area of 45.51 km2 and with its mouth on the Japaratuba River, in the municipality of Japaratuba (SE). The Lagartixo creek microbasin is one of the main sources of water for approximately 34,514 inhabitants of the municipality of Capela and also serves for local economic development. Having important relevance because its source is inserted within a UC (Conservation Unit). Given its relevance for the region, the present study aims to value the goods/services provided by the Lagartixo stream for the municipality of Capela/SE as an environmental management instrument. The method used was VERA, which is based on estimating monetary values through the direct and indirect use of this system. The valuation of natural resources attributed to water resources showed the value of 35 million reais per year, the analyzed value refers to the production of water in the public supply and the ecosystem functions understood by the hydrographic microbasin area. The results achieved show that there is the possibility of assigning monetary values to the services provided by aquatic ecosystems using the VERA method in order to understand the importance of the sustainable use of such systems.
