O Futuro Incerto das Florestas Tropicais The Uncertain Future of Tropical Forests

Abstract

As florestas tropicais dão abrigo à maior biodiversidade do planeta, são residência de populações indígenas, fontes de madeira e produtos farmacêuticos, contribuem para regular o clima e prestam uma diversidade de serviços ecológicos vitais - e, contudo, estão ameaçadas de desaparecimento total. As causas desta intensa desflorestação tropical são múltiplas, diferem aos níveis regional e nacional e são simultaneamente de carácter endógeno e exógeno, como é discutido. É também discutida a importância das florestas tropicais para a preservação da diversidade biológica e redução do aquecimento global, pelo sequestro do CO2. Finalmente, são referidas as áreas de desflorestação nalgumas importantes regiões da África, Índia e sudeste asiático e discutidas as suas principais causas.Tropical forests harbour most of the planet biodiversity, are home to indigenous people, sources of timber and pharmaceutical products, contribute to the regulation of the climate and provide an endless number of vital ecological services. However, they are at risk of disappearing. The causes of this rampant tropical deforestation are multiple and differ at the regional and national levels, being both endogenous and exogenous, as is discussed. The importance of tropical forests for preserving biological diversity and reducing global warming by sequestering CO2 are also discussed. Finally, we assess the extent of deforestation and discuss its major drivers in some important regions of Africa, India and southeast Asia.
