Deforestation is defined as the conversion of forest to other land uses (regardless of whether it is human-induced). [14] Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period. Net change, therefore, can be positive or ...
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 countries: Russia , Brazil , Canada , the United States , China , Australia , the Democratic Republic of the Congo , Indonesia , India , and Peru .
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 during the burning of forest biomass and decomposition of remaining plant material and soil carbon.
The direct cause of most deforestation is agriculture by far. [33] More than 80% of deforestation was attributed to agriculture in 2018. [34] Forests are being converted to plantations for coffee, palm oil, rubber and various other popular products. [35] Livestock grazing also drives deforestation.
In a year period, spanning from August 2019 to July 2020, deforestation in the world's largest rainforest increased by nearly 10%. In a year period, spanning from August 2019 to July 2020 ...
Deforestation occurs when humans remove trees from a forested area by cutting or burning, either to harvest timber or to make way for farming. Most deforestation today occurs in tropical forests. The vast majority of this deforestation is because of the production of four commodities: wood, beef, soy, and palm oil. [15]
Tropical deforestation: In most cases of tropical deforestation, three to four underlying causes are driving two to three proximate causes. [19] This means that a universal policy for controlling tropical deforestation would not be able to address the unique combination of proximate and underlying causes of deforestation in each country. [19]
Deforestation is the main land use change contributor to global warming, [62] Between 1750 and 2007, about one-third of anthropogenic CO 2 emissions were from changes in land use - primarily from the decline in forest area and the growth in agricultural land. [63] primarily deforestation.
