Avaliação econômica da implementação da cobrança do uso da água na bacia hidrográfica do rio Coruripe/AL

Abstract

Water is a finite natural resource with economic value, as established by Law No. 9,433 of 1997, which establishes the National Water Resources Policy (PNRH). Therefore, charging for the use of water is an important instrument in the control of water resources, through which it can contribute to sustainable development, boosting the rationalization of water and promoting economic benefits for river basin plans. In this context, this paper aims to investigate the implementation of charging for water use in the state of Alagoas, specifically in the Coruripe River Basin, highlighting institutional and legal aspects. In relation to Alagoas, this is a significant milestone in the management of water resources, given that it should guarantee water availability and quality for subsequent societies, as proposed by Article 225 of the 1988 Federal Constitution “Everyone has the right to an ecologically balanced environment, a good for the common use of the people and essential to a healthy quality of life, and the public authorities and the community have the duty to defend and preserve it for present and future generations”. With this in mind, this research uses the model proposed by the Alagoas State Secretariat for the Environment and Water Resources for the implementation of charging. In addition, the study explores the process of economic impacts on collection, as well as the possible difficulties faced by the public sector and water users. Therefore, this research results in a critical and comparative analysis of water charging mechanisms, in order to contribute to the effectiveness and improvement of this management instrument.
