The objective of this study is the analysis of Environmental Services Payments programs (PES) in the face of the concept of green economy, through a systemic approach of theoretical and practical studies that make up the knowledge on the subject. Case studies implemented in Brazil and the world were analyzed to complement the literature review. Was also carried out a survey of Brazilian legislation relevant to the PES. The current model of economic growth is socially, environmentally and economically unsustainable. Bringing out the need for the international community to engage in a transition to a green economy in order to ensure a sustainable and desirable future that promotes social equity, poverty eradication, environmental protection and human wellbeing. This focus has been complemented by growing appreciation of biodiversity, ecosystem services and the economic value of nature. In this context, the concept of Payment for Environmental Services (PES) has emerged as a potential mechanism to provide the conservation of ecosystems and the improvement of environmental livelihoods of service providers and consumers. The case study chosen to exemplify the proposed objectives, was the simulation using the program methodology Water Producer the catchment area of the river Pirajibu. Scenarios have been proposed with different soil conservation practices to areas covered with pasture. It was determined by estimating the opportunity cost, the Reference Value (VRE) to the PES. The scope of the case study was extended to analyze four possible scenarios of land use with different soil conservation practices. Under the proposed conditions, the worst erosion abatement scenario would be using pasture recovered by subsoiling, the acidity or fertilization correction may submit a PAE at least 25% value. The best scenes are framed in the pasture recovered with soil conservation (barraginhas or terraces, while using the mechanical and vegetative...
