| Resumo | Tropical forests throughout the world are disappearing or deteriorating to a very rapid pace. Among the most significant causes is the change in land use by the conversion of land use to agriculture, pasture, or urbanization. Selective logging and natural factors also account for a large portion of tropical forest loss. Although there are large efforts by national and international governments and agencies to curtail the rapid loss of such forests, there is a disturbing increasing trend of loss of tropical forest resources. There are apparent successes in government programs, but gains seem only temporary. For instance, massive deforestation occurred in the Brazilian Amazon forest during the 1970s and 1980s. It does continue but slowed down on the 1990s due to Brazils government policies. However, recent assessments show that it is on the increase again and now with different spatial patterns than before (Skole and Tucker 1993, INPE 2002, INPE 2003, Laurance et al. 2001). Occurrence of catastrophic wildfires in the last few decades in different parts of the world has raised awareness of devastating local and regional effects and the potential impact across international borders. In addition, a steady increase of wildfire risk has been detected in the last couple of decades in temperate and tropical ecosystems. Noticeably, uncontrollable wildfires in the tropics have increased in number and extent at rates higher than temperate forests. Ordinarily, undisturbed tropical rain forest is considered a fireproof ecosystem, however, severe fires occur during sustained droughts when the ecosystem is dry enough to sustain smoldering combustion, or when the canopy is disturbed by natural events or human activities. Those climate and forest conditions are concurring more often in the tropical world. The 1998/99 wildfire seasons in Mexico, Central America, Amazônia, and several other countries across the world signaled how vulnerable tropical ecosystems are becoming to wildfires and that the immediate effects can be felt across borders. The tropical southern Mexico and the state of Roraima in the northern Brazilian Amazon were heavily impacted during that wildfire season (Cairns and others 1998; Kirchhoff and Escada 1998). Extensive damage has also been observed in several parts of the Amazonian forest. These severe and extensive wildfires are a threat to the ecological integrity, biodiversity and sustainability of tropical forests. Those severe fire seasons also have shown that some land use/land cover types are more vulnerable than other types and that generalizations cannot be made in terms of flammability or carbon emissions from tropical ecosystems. An increasing amount of fire usage, coupled with large areas of forest vulnerable to fire, creates a new threat to the integrity and sustainability of the tropical forests in Amazonia and elsewhere in the tropical world. Forest wildfires that start form from escaped agriculture and rangeland fires are becoming more common throughout the tropical world. Fire has been observed to spread under the canopy for long distances and smolder for long periods on rotten trunks where it can remain active for long periods. Those accidental fires cause approximately onehalf of the area burned in the Amazon forest of Brazil, and are often associated fires that start in adjacent areas cleared for agriculture or transportation corridors (Nepstad and others 1999, Uhl and Kauffman 1990). |
