What Drives Deforestation in the Brazilian Amazon?
While previous empirical analysis of deforestation focused on population, this paper builds from a model of land use which suggests many determinants of deforestation in the Brazilian Amazon. I derive a deforestation equation from this model and test a number of those factors using county-level data for the period 1978]1988. The data include a satellite deforestation measure which allows improv...
متن کاملPredictive Modelling of Contagious Deforestation in the Brazilian Amazon
Tropical forests are diminishing in extent due primarily to the rapid expansion of agriculture, but the future magnitude and geographical distribution of future tropical deforestation is uncertain. Here, we introduce a dynamic and spatially-explicit model of deforestation that predicts the potential magnitude and spatial pattern of Amazon deforestation. Our model differs from previous models in...
متن کاملLan Occupations and Deforestation in the Brazilian Amazon
Researchers are increasingly interested in understanding the impact of contentious social processes on land change. In the Brazilian Amazon, there are often contentious interactions between landholders defending private property rights and squatters who have the right to occupy land that is deemed unproductive. Previous studies suggest that the contentious social processes inherent in the Brazi...
متن کاملDeforestation Slowdown in the Brazilian Amazon: Prices or Policies?
Deforestation and biomass decay have accounted for approximately 17% of global greenhouse gas emissions (IPCC, 2007).1 This raises concerns about the extent of forest clearings in the Amazon, the planet’s largest rainforest tract. The region has long been the world’s most active agricultural frontier in terms of forest loss and CO2 emissions. In Brazil, the conversion of forest areas in the Def...
متن کاملThe future of deforestation in the Brazilian Amazon
Concern about the future of Amazonian forests is growing as both the extent and rate of primary forest destruction increase. We combine spatial information on various biophysical, demographic and infrastructural factors in the Brazilian Amazon with satellite data on deforestation to evaluate the relative importance of each factor to deforestation in the region. We assess the sensitivity of resu...
