Examining interactions between large-scale land cover and land use change and regional climate in areas undergoing dynamic land transformations, like the Brazilian Cerrado, is crucial for understanding tradeoffs between human needs and ecosystem services. Yet regional climate models often do not include accurate land cover data of these complex landscapes. We use National Center for Atmospheric Research’s Weather Research and Forecasting (WRF) model coupled to the Noah-Multiparameterization (Noah-MP) land surface model to run 10-year climate simulations across Brazil to assess (1) whether an accurate, regionally validated land cover data set with two, new agricultural land cover classifications improves model simulation …

The Amazon basin has been subjected to unprecedented rates of land-use change over the past several decades, primarily as a result of the expansion of agriculture. Enhanced rain forest conservation efforts toward the end of the twentieth century slowed deforestation of the Amazon but, in turn, increased demand for land repurposing in the adjacent Cerrado (savanna) region, where conservation regulations are less strict. To maintain or increase yields while minimizing the need for additional land, agricultural producers adopted a form of intensification in which two rain-fed crops are planted within a single growing season (double cropping). Using 10 years (August …

El objetivo preliminar de este estudio fue determinar las características del uso de tierra de cinco comunidades indígenas representadas por cuatro grupos culturales dentro de la zona de influencia nordeste. Un segundo objetivo fue el de averiguar cómo y en qué grado las fuerzas económicas y culturales están influenciando las decisiones con respecto al uso de la tierra. Los resultados de este estudio son preliminares, pero esperamos que la información sea de alguna utilidad para los administradores de esta área protegida.
