Abstract

The process of occupation of land use in the Amazonia has resulted in a high fragmentation of the landscape in the last decades, resulting in changes in the local and regional climate. The Amazonia has an important role in the moisture transport that influences precipitation over La Plata River Basin (BRP). Therefore, it is interesting to know the potential effects that the land use and land cover change in the Amazonia have on the water balance over La Plata River Basin. Simulations with the Eta/Noah-MP regional model will be carried out for the historical and future climates over the South America, using two different scenarios of the land use and land cover change for the Amazonia. The subgrade heterogeneity will be represented by a tile approach. The study aims to adapt the regional projections of climate change including plausible scenarios of land use and land cover, developing knowledge on this topic. The results of the numerical integrations will also allow hypotheses to be drawn about the mechanisms of interaction between atmosphere and surface and their effects both local and remote. Also, the research will result in the innovation of regional modeling for the theme of land use and land cover change. (AU)
