A quarter of the deforested Amazon has regrown as secondary tropical forest and yet the climatic importance of these complex regenerating landscapes is only beginning to be recognised. Advances in satellite remote-sensing have transformed our ability to detect and...
The spatial distribution of human activities in forest frontier regions is strongly influenced by transportation infrastructure. With the planned paving of 6000 km of highway in the Amazon Basin, agricultural frontier expansion will follow, triggering potentially...
Amazônia contains vast stores of carbon in high-diversity ecosystems, yet this region undergoes major changes in precipitation affecting land use, carbon dynamics, and climate. The extent and structural complexity of Amazon forests impedes ground studies of...
Timber is a strategic resource in Amazon frontier development, providing 250,000 jobs and up to one-fourth of the region’s gross domestic product (Uhl et al. 1997; Veríssimo et al. 2002a, 2002b). Since the 1980s, timber sales have replaced government subsidies as...
Amazonia contains more carbon (C) than a decade of global, human-induced CO2 emissions (60–80 billion tons). This C is gradually being released to the atmosphere through deforestation. Projected increases in Amazon deforestation associated with investments in road...
Root penetration rate was estimated for the liana Davilla kunthii St. Hill (Dilleniaceae) in a secondary forest in eastern Amazonia by relating aboveground growth with root depth measurements. Basal diameter, height, number of leaves and number of scars of...
Bolivia has undertaken important policy reforms since the mid-1990s aimed at institutionalising popular participation and promoting democratic decentralisation. In the forestry sector, municipal governments have received responsibilities and various mechanisms have...
