Food security and climate change are two pressing issues shaping the future of tropical land use. Brazil, home to abundant land that is rich in carbon, water, and biodiversity and often cleared for agropastoral and renewable energy purposes, is the ideal location for studying socioeconomic and environmental trade-offs of land use dynamics. Here, I use recent (2000–2016) land-use land-cover change dynamics in the established agricultural states of Mato Grosso and Goia's to demonstrate how incentivizing intensive agricultural practices and improving degraded pastures may be a means by which Brazil can increase agricultural production while conserving the remainder of the Cerrado. …

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 …
