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.
Deforestation is an example of large-scale land use change. The deforestation of temperate regions since 1750 has had a major effect on land cover. [19] The reshaping of landscapes to serve human needs, such as the deforestation for farmland, can have long-term effects on earth systems and exacerbate the causes of climate change. [20]
Deforestation in the city of Rio de Janeiro in Brazil's Rio de Janeiro state, 2009. Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. [1] Deforestation can involve conversion of forest land to farms, ranches, or urban use.
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 causes many threats to wildlife as it not only causes habitat destruction for the many animals that survive in forests, as more than 80% of the world's species live in forests but also leads to further climate change. [8] Deforestation is a main concern in the tropical forests of the world.
Deforestation: This is the clearing of forests for agricultural, urban, or industrial development. Deforestation can have a number of negative environmental impacts, including soil erosion, flooding, and climate change. Urbanization: This is the growth of cities and towns. Urbanization can lead to the conversion of agricultural land, forests ...
Deforestation in Madagascar is an ongoing environmental issue. Deforestation [ 1 ] creates agricultural or pastoral land but can also result in desertification , water resource degradation , biodiversity erosion and habitat loss, and soil loss .
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.
