Brazil has a privileged position in the agricultural world market notably because of its productivity gains and the incorporation of new agricultural frontiers. The expansion of agricultural frontiers has caused substantial changes in land use and land cover in the country. In this research, we aim to analyze the space-time dynamics of soybeans and livestock production in the Brazilian territory during the period 1991-2015. The data used were the time series of municipal production from the Brazilian Institute of Geography and Statistics. The spatial analysis adopted the following procedures: (a) change vector from the annual calculation of the midpoint of production; (b) mapping of the growth and acceleration rates of the two productions, and (c) mapping of correlation between the time series of soybean and livestock. The results showed high rates of growth and acceleration for soy production in the South, Central-West and Matopiba (which aggregates Maranhão, Tocantins, Piauí and Bahia states) regions. The results demonstrate the effects of Brazil's Soy Moratorium, promulgated in 2006, contained soybean expansion into the Amazon region. However, as a side effect, soybean production replaces livestock production in the savanna region, which in turn migrates to the Amazon rainforest. The inverse correlation in the municipalities of the Central-West, South and Matopiba regions indicates the conversion of pasture to soybean. This coupled dynamics of soy and livestock act on two fronts of deforestation. We highlight the importance of public policies that comprehensively understand the spatial-temporal dynamics of Brazilian agriculture to promote sustainable land-use practices.
