Biofuels, cropland expansion, and the extensive margin
Background: Recently, several papers have assessed land use consequences of biofuel expansion. In the absence of empirical evidence, these papers assigned subjective values to extensive margin (productivity of new croplands over productivity of existing croplands). Methods: This paper fills the gap in this area and provides a new data set which estimates land productivity at 0.5° × 0.5° (longit...

متن کاملWatershed responses to Amazon soya bean cropland expansion and intensification.
The expansion and intensification of soya bean agriculture in southeastern Amazonia can alter watershed hydrology and biogeochemistry by changing the land cover, water balance and nutrient inputs. Several new insights on the responses of watershed hydrology and biogeochemistry to deforestation in Mato Grosso have emerged from recent intensive field campaigns in this region. Because of reduced e...

متن کاملCropland expansion changes deforestation dynamics in the southern Brazilian Amazon.
Intensive mechanized agriculture in the Brazilian Amazon grew by >3.6 million hectares (ha) during 2001-2004. Whether this cropland expansion resulted from intensified use of land previously cleared for cattle ranching or new deforestation has not been quantified and has major implications for future deforestation dynamics, carbon fluxes, forest fragmentation, and other ecosystem services. We c...
