Ecology: The Tropical Deforestation Debt
Tropical deforestation is a significant cause of global carbon emissions and biodiversity loss. A new study shows that deforestation today leaves a carbon and biodiversity debt to be paid over subsequent years. This has potentially profound implications for forest conservation.
متن کاملDeforestation and tropical insect extinctions.
In a study comparing historical and recent records of forest-dwelling Helictopleurus dung beetles across Madagascar, Hanski et al. (2007) reported that species not found in Madagascar-wide sampling in 2002– 2006 have experienced a significantly higher level of deforestation within their known geographical ranges than those species that were recorded. They suggested that deforestation is respons...
متن کاملTropical Deforestation in the Amazon
Tropical forests are a unique environmental resource that provide numerous global benefits. Of the world's biomes, they provide the greatest biological diversity of plants and animals. It is estimated that these forests contain at least fifty percent of the world's animal species and almost seventy five percent of the world's plant species. Increased deforestation is likely to reduce this biodi...
متن کاملReducing uncertainties on carbon emissions from tropical deforestation: Brazil Amazon study case
In the last year, Brazil announced the voluntary commitment to reduce its greenhouse gas emissions from 36.1% to 38.9% by 2020 and, to this end, such a commitment requires cutting down 80% of the deforestation in the Amazon rainforest until that year. Much of the uncertainty on the role of forests for carbon emissions is due to the lack of reliable deforestation data. The Brazilian’s National I...
متن کاملGlobal biodiversity loss from tropical deforestation.
Tropical forests are incredibly biodiverse; they support at least two-thirds of the world’s biodiversity (1) despite covering less than 10% of Earth’s land surface (2). Unfortunately, prospects for tropical forests and the biodiversity therein are becoming increasingly bleak owing to unabated deforestation and forest alteration (3) that stem from human activities such as logging, hunting, agric...
