Análise dos serviços de geodiversidade na bacia hidrográfica do Rio São Francisco em Minas Gerais

Abstract

Geodiversity is a concept used since the 1990s to designate the abiotic elements of nature as well as their active processes. Since its inception, its use has become common in scientific jargon with application in various contexts in environmental studies. The approaches include research involving geotourism, geoconservation, quantification of geodiversity, in addition to its valuation through its goods and services, among others. Geosystemic services are the benefits (goods and services) that people derive from nature and can be divided into four broad categories: regulation, support, provision, and cultural services. In Brazil, research on geodiversity, although it has increased in recent years, is still incipient and there is much to be done. In this context, the work aims to map and analyze the geodiversity services of the São Francisco River basin (Minas Gerais portion) using the Water Resources Planning and Management Units (UPGRHs) as a reference. The research methods involved six steps: selection and acquisition of data, treatment and spatialization of the database, data normalization, overlay of geodiversity services, kernel analysis and examples of highlighted services. The results indicate the UPGRH SF5 with great availability of geodiversity services. Other UPGRHs also stand out as the UPGRHs SF1, SF3 and SF7. It is believed that this work contributes in an innovative way in the perspective of the management of water resources by the State of Minas Gerais by offering an analysis of the existing geodiversity services in the São Francisco River Basin considering its UPGRHs.
