Responses of water resources to land and soil management in a tropical small watershed under a Payment for Environmental Services public policy. Repositório Alice

The 12-km2 Ribeirão das Posses Watershed (RPW), which is dominated by Ultisols and Inceptisols, is located in the south of Minas Gerais, Brazil. RPW discharges into the Jaguarí River, one of the most contributing rivers to supply the São Paulo metropolitan area. Over the last century in this watershed, the land use changed from native forests to more homogeneous vegetation for pastures, crops and forest plantations of eucalyptus, which have cumulative impacts on water yield and quality. To address this, a public policy was adopted establishing the Payment for Environmental Services covering three small watersheds of this river basin, including RPW. Since 2004, under such initiative, some small areas with vegetation of native species have been planted,...

Stream water quality monitoring as a tool to evaluate a payment for environmental service in Extrema (Minas Gerais), Brazil. Repositório Alice
FIGUEIREDO, R. de O.; SIMIOLI, M. M.; CRUZ, P. P. N. da; GREEN, T. R..
Posses and Salto de Cima small catchments (1,200 ha and 1,500 ha, respectively) are situated in the municipality of Extrema (MG), southeast Brazil. Their stream outlets enter into the Jaguari River, an important tributary to the Cantareira Reservoir, which supplies part of the water demand of the São Paulo metropolitan area. These catchments, with pastures as the dominant land use, have been targets of a payment for environmental service program that aims to face successive water deficit that has occurred in the region. Possible improvement of water resources has been investigated by this present hydrobiogeochemical study. Evaluations included the temporal variation of water quality parameters as well as a comparison of two monitored streams in relation to...
