Valoração econômica ambiental de recursos hídricos: números no Brasil

Abstract

The growing demand for alternatives to manage natural resources made environmental economic valuation a target for interdisciplinary research. Once this is an incipient theme, it is needed to research methodologies able to identify problems and potential solutions to consolidate support to the environmental economic valuation (EEV). Considering this context, in this article the Brazilian research panorama was analyzed and the conceptual accuracy on workspublished on peer reviewed Brazilian journals was verified.For that purpose, it was made a systematic review on works listed on the Scholar Google base in which terms such as "valuation" and "water resources" were present. It was verified how many of them accomplished the propose of valuating water resources, considering the application of pertinent methods for capturing the value components of the environmental service. 367 works were part of this analysis, revalidating the records for identifying the objectives and methodological scientific criteria adopted on them. 19% of the total corresponded to publications in journals, of which just 14% really were about water resources valuation. On the Qualis classification system, 20% of such works were positioned in the A stratum, 70% in B stratum and 10% in C stratum. Itis concluded that despite Brazil occupying a highlight position in the terms of water resources, its literature is scarce and inexpressive. Therefore, it is essential to increase scientific production on EEV to provide a theoretical base for more effective water resources management.
