Deforestation by continent. In decades since 1990, South America and Africa have shown the greatest loss of forest area, with global net loss in the 2010s still about 60% of the 1990s value. [1] Rates and causes of deforestation vary from region to region around the world. In 2009, two-thirds of the world's forests were located in just 10 ...
Deforestation is a primary contributor to climate change, [1][2] and climate change affects the health of forests. [3] Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. [4][5] Greenhouse gases are emitted from deforestation ...
Deforestation in Brazil. Brazil once had the highest deforestation rate in the world and in 2005 still had the largest area of forest removed annually. [1] Since 1970, over 700,000 square kilometres (270,000 sq mi) of the Amazon rainforest have been destroyed. In 2001, the Amazon was approximately 5,400,000 square kilometres (2,100,000 sq mi ...
Forest degradation is a process in which the biological wealth of a forest area is permanently diminished by some factor or by a combination of factors. "This does not involve a reduction of the forest area, but rather a quality decrease in its condition." The forest is still there, but with fewer trees, or less species of trees, plants or ...
The overwhelming direct cause of deforestation is agriculture. [9] Subsistence farming is responsible for 48% of deforestation; commercial agriculture is responsible for 32%; logging is responsible for 14%, and fuel wood removals make up 5%. [9] More than 80% of deforestation was attributed to agriculture in 2018. [10]
Desertification in Africa is a form of land degradation that involves the conversion of productive land into desert or arid areas. This issue is a pressing environmental concern that poses a significant threat to the livelihoods of millions of people in Africa who depend on the land for subsistence. [1][2] Geographical and environmental studies ...
Deforestation is the main land use change contributor to global warming, [126] as the destroyed trees release CO 2, and are not replaced by new trees, removing that carbon sink. [127] Between 2001 and 2018, 27% of deforestation was from permanent clearing to enable agricultural expansion for crops and livestock.
t. e. Deforestation in the Maranhão state, Brazil, in July 2016. The Amazon rainforest, spanning an area of 3,000,000 km 2 (1,200,000 sq mi), is the world's largest rainforest. It encompasses the largest and most biodiverse tropical rainforest on the planet, representing over half of all rainforests. The Amazon region includes the territories ...
