The potential impact of deforestation in the Brazilian Amazon on greenhouse gas emissions to the atmosphere calls for policies that take account of changes in forest cover. Although much research has focused on the location and effects of deforestation, little is known about the distribution and reasons for the agricultural uses that replace forest cover. We used Landsat TM-based deforestation ...

Deforestation contributes about 18% of all carbon emissions and leads to species extinction. In the context of climate change negotiations, international community agreed to compensate efforts made by countries toward forest protection. Forest covers approximately 80 % of the Congo basin with more than half classified as dense forest. It is estimated that Congo Basin rainforest has been rather ...

Malaria is the most prevalent vector-borne disease in the Amazon. We used malaria reports for health districts collected in 2006 by the Programa Nacional de Controle da Malaria to determine whether deforestation is associated with malaria incidence in the county (municipio) of Mancio Lima, Acre State, Brazil. Cumulative percent deforestation was calculated for the spatial catchment area of each...

Deforestation ranks at the top in the global environmental agenda. Its importance is prompted by economic and ecological roles played by the forests and the notable adverse effects caused by deforestation on human and other species. These effects include biodiversity loss, greenhouse gas emissions, disruption of water cycles, increasing soil erosion and disruption of livelihoods. Deforestation ...

A mosaic of protected areas, including indigenous lands, sustainable-use production forests and reserves and strictly protected forests is the cornerstone of conservation in the Amazon, with almost 50 per cent of the region now protected. However, recent research indicates that isolation from direct deforestation or degradation may not be sufficient to maintain the ecological integrity of Amazo...

Software engineering has to reconcile modularity with ee-ciency. One way to grapple with this dilemma is to automatically transform a modular-speciied program into an eecient-implementable one. This is the aim of deforestation transformations which get rid of intermediate data structures constructions that appear when two functions are composed. Nevertheless, existing functional methods cannot ...

The height of the annual flood crest of the Amazon at Iquitos has increased markedly in the last decade. During this same period, there has been greatly increased deforestation in the upper parts of the Amazon watershed in Peru and Ecuador, but no significant changes in regional patterns of precipitation. The change in Amazonian water balance during the last decade appears to be the result of i...

The extent and consequences of deforestation and related environmental degradation in the developing world have become the subject of considerable debate and concern. There is disagreement about how rapidly tree-covered land near the equator is being cleared or otherwise disturbed. Likewise, tropical deforestation's impacts have proven difficult to identify and to evaluate. By contrast, the con...
