Simulação dos impactos econômicos sobre a renda agrícola com a implementação do programa produtor de água na Bacia do Ribeirão Pipiripau

Abstract

Urban growth and predatory agriculture has had negative impacts on the flow of environmental services and products provided by ecosystems around the world. In Brasil several actions and programs, with different degrees of effectiveness, have been developed by the federal, state and municipal governments. One of them is the management model and compensation scheme proposed by the so-called Water Producer Project (Programa Produtor de Água), developed by the Brazilian National Water Agency (ANA). The main instrument of the project is to compensate monetarily, with a fixed amount, social actors who adopt practices that support natural resource conservation and management. One of the potential effects of the project is to reduce the area under agricultural cultivation since farmers, once in the project, will have to reallocate land under cultivation to conservation areas. This dissertation uses primary data and linear and non-linear programming techniques to estimate the impacts of such land reallocation on farmers income. In particular, given the fact that participation will be voluntary, this study shows that the compensation amount proposed by ANA will not be sufficient to compensate for farmers that will have to reduce land under cultivation by 10% or more. Therefore, the currently stipulated compensation amounts may not offer enough incentives for farmers to adhere to the programme.
