Deforestation Estimates in Avhrr/noaa and Tm/landsat Images for a Region in Central Brazil
This paper presents a comparison of tropical deforestation estimates in AVHRR/NOAA and TM/Landsat images for a region in Central Brazil where large clearings in the forest prevail. A TM scene of 02/Sept/89 in the scale of 1:250,000 was visually interpreted to produce a map with four classes: natural forests, deforested areas, natural savannahs, and rivers. The AVHRR image of 17/Sept/89 with ful...
متن کاملWhat 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 کاملCarbon emissions from deforestation in the Brazilian Amazon Region
A simulation model based on satellite observations of monthly vegetation greenness from the Moderate Resolution Imaging Spectroradiometer (MODIS) was used to estimate monthly carbon fluxes in terrestrial ecosystems of Brazilian Amazon and Cerrado regions over the period 2000–2002. The NASA-CASA (Carnegie Ames Stanford Approach) model estimates of annual forest production were used for the first...
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...
متن کاملEnvironment. The end of deforestation in the Brazilian Amazon.
G. VOGEL’S NEWS STORY “FOR MORE PROTEIN, FILET OF CRICKET” (12 FEBRUARY, SPECIAL section on Food Security, p. 811) draws attention to the potential role of insects in food security. Although insects such as mopane worms and termites are widely consumed by some societies, especially in Africa (1–7), globalization and creation of a food culture based largely on Western values has led to their mar...
