%X Brazil is among the top agriculture producers in the world and much of this is due to technological advances, which have resulted in grain yield increases in the last decades, along with land availability for the expansion of the agriculture frontier. However such expansion faces criticisms due to its close relation to Land Use and Cover changes, be it through direct conversion of natural lands to crop plantations or through indirect land use change caused by the conversion of deforested areas from one land use to another. Here we analyze terrain slope and climatic water balance variables of annual crop production areas in the Cerrado biome, Brazil, and compare these to established pasture areas in order to evaluate land availability for cropland expansion. This study does not take into account soil properties (fertility, drainage) or legal limitations i.e. Brazilian Forest code. Results indicate that 445 thousand km2 of pasture areas in the Cerrado biome presents slope and climatic characteristics (annual precipitation, annual water deficit and surplus) suitable for agriculture. More than half of the lands with slope between 0 and 3% are located within 15 km of agricultural areas already established. The states of GO and MS holds the largest amount of suitable lands. In GO, 72% of the flattest areas (0 3% slope) are located within 15 km of established agricultural areas while in MS, only 48% is located within that distance.
