Abstract

Abstract One of the benefits of forest and reforestation is linked to the erosion control and reduction of the amount of sediments suspended in water. This study proposes a methodology for Payments for Ecosystem Services associated to these benefits in 24 water supply watersheds, under influence of the Paraíba do Sul River Basin Environmental Protected Area, in Brazil. In order to estimate the water resources protection through the reforestation, the current scenario was compared to a hypothetical scenario, in which degraded pasture are replaced by forest. The avoided soil erosion could reach around 40t.ha-1.yr-1. Reforestation can avoid expenditures in water treatment, sludge disposal and dredging around USD 7.8 million per year. Annual values for PES range from USD 6 to 3,014 per hectare of reforested area. The results highlight the importance of valuing the benefits of the ecosystem services rescued. (AU)
