A characterization of ecosystem services, drivers and values of two watersheds in São Paulo State, Brazil

Caracterização dos serviços do ecossistema, valores e forçantes de duas bacias hidrográficas no estado de São Paulo, Brasil

Abstract

The evaluation of ecosystem services is a tool to raise awareness about benefits of ecosystem functions for human well-being. In Brazil, few studies and reports assess ecosystem services in a watershed context. The aim of this paper is to fill this gap by assessing ecosystem services of Jacaré-Guaçu and Jacaré-Pepira Watersheds (São Paulo State, Brazil) in a temporal scale of 10 years. Land cover and uses’ capacity to provide ecosystem services and drivers were assessed as a result of mapping these areas. Economic values were estimated based on literature information. Results showed that cultivated and managed terrestrial areas stands out over other areas and then, regulation and maintenance services are reduced in these areas. Wetlands and natural vegetation, with smaller areas, are important for the supply of regulation and maintenance services of both watersheds and economic values indicate the magnitude of degradation or maintenance/restoration.
