Evaluation in public policy on renewable natural resources management in Parana' State: economic and environmental impacts

The paper's objective was to evaluate the effectiveness of renewable natural resources management in the State of Parana, in an approach aimed at economic and environmental impacts. It was based on a case Study in areas with unsuccessful incentives and unclarified frauds. The research diagnosed the land tenure and possession structure on the coast of the State of Parana, by relating data provided by Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renovaveis - IBAMA on heart-of-palm trees (Euterpe edulis Martius) reforestation projects in the 1970's with cutting and management plans granted. The results indicate that the researched areas are vitiated, with overlappings of tenure titles and land disputes. An analysis of native heart of palm management plans confirmed ineffectiveness, as cuts were allowed in illegal areas, contributing toward Atlantic Forest degradation. The distortions verified in the study remain to the present day, in acquisitions of Conservation Units, in proceedings for the acknowledgement of Reservas Particulares do Patrimonio Natural - (RPPN - Private Natural Heritage Reserves), in Forest Certification - FSC, or in environmental ventures such as the carbon trade, and may constitute a network.
