Abstract: The choice of areas for nature conservation involves the attempt to maximize the benefits, whether by carrying out an economic activity or by the provision of Ecosystem Services. Studies are needed to improve the understanding of the effect of the extent and position along the watershed of restored areas on soil and water conservation. This study aimed to understand how different restoration strategies might reflect in soil conservation and sediment retention. Using InVEST tool, sediment transport was simulated in a small 12 km2 watershed (Posses River, in Southeast Brazil), where one of first Brazilian Payment for Ecosystem Services (PES) projects is being carried out, comparing different hypothetical restoration strategies. With 25% of restoration, sediment export decreased by 78% for riparian restoration, and 27% for the steepest slopes restoration. On the other hand, the decrease in soil loss was lower for riparian restoration, with a 16% decrease, while the steepest slopes restoration reduced it by 21%. This mismatch between the reduction of sediment export and soil loss was explained by the fact that forest not only reduces soil loss locally but also traps sediment arriving from the upper parts of the watershed. While the first mechanism is important to provide soil stability, decreasing the risk of landslip, and to maintain agricultural productivity, the second can improve water quality and decrease the risk of silting, with positive effects on the water reservoirs at the outlet of the watershed. This suggests that Riparian and the Steepest Slopes restoration strategies are complementary in the sense of preventing sediments from reaching the water bodies as well as protecting them at their origin (with the reduction of erosion), so it will be advisable to consider the two types of restoration.

A microrregião de Paragominas, Estado do Pará, face ao interesse de Produtores Rurais e do Governo do Estado pelo incentivo à produção de soja, vem crescendo sua área plantada, e se constituindo em polo produtor de grãos no estado. A Embrapa Amazônia Oriental e a Embrapa Soja em atenção a essa demanda vem conduzindo experimentos visando avaliar o comportamento de cultivares de soja na região. Os experimentos foram instalados no campo experimental da Embrapa Amazônia Oriental que fica a cerca de 12 Km da cidade de Paragominas, a qual está localizada a 02º 57' 24" latitude Sul e altitude é de 85 m. A umidade relativa e a precipitação média anual na região é de 81% e 1.801 mm, respectivamente. Em experimentos conduzidos no período de 1997 a 2002, destacaram-se as cultivares: BRS Sambaíba, BRS Tracajá, BRS Babaçu, BRS Seridó RCH, com rendimentos médios de 3.861, 3.768, 3.431 e 3.258 kg/ha, respectivamente. Propõe-se com estes resultados, manter a indicação dessas cultivares para cultivo na microrregião de Paragominas.
