Conteúdo: | Norman Borlaug, the so-called "Father of the Green Revolution," hypothesized that modern agriculture, through high yields, has helped minimize the areal extent of agriculture, thus saving natural environments around the world, especially in the tropics, from being converted to cropland. We ask how much of the recent increase in total mechanized agricultural production in the Brazilian Amazon originates from activities on recently deforested lands, and how much originates from non-forested lands? The answer to this question will be used to test the Borlaug hypothesis. The hypothesis is often the very basis for agricultural development and environmental conservation strategies throughout the world, but it has rarely been tested empirically. This project will conduct such a test over nearly all mechanized agricultural areas in the Brazilian Amazon. This test is novel: it links increases in total production to precise land use and land cover changes comprising the two factors of the total production equation - area and yield ? in a spatially and temporally explicit way using remotely sensed data. We also discuss the implications of the results for development policy in the region.
