Uso de instrumento de suporte à tomada de decisão para gestão dos recursos hídricos no estado de Minas Gerais

Abstract

The aim of this study was to evaluate the application of the National Water Resources Policy (PNRH) in Minas Gerais state, analysing the implementation of its instruments. In order to achieve this, two indicators related to the implementation of the PNRH instruments (composed of five verifiers) and the performance ofthe river basin committees (composed of three verifiers) in each Planning and Management Unit for Water Resources (UPGRH) were established. Each verifier was analysed in relation to its compliance percentage. Weights were also assigned to verifiers through the Analytical Hierarchical Process. Based on these figures, it was possible to calculate the Effective Contribution Index of the PNRH instruments in the state of Minas Gerais, estimated at around 71%. Although the index is considered high, the approval of water bodies classification, charging for water use, and operation of river basin agencies is still insufficient in the state. The methodology applied in the present study proved to be adequate for the evaluation of the proposed criteria, allowing, also, the aggregation of new criteria for the evaluation of PNRH management instruments.
