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.
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 .
The rising temperatures cause massive wildfires especially in the Boreal forests. One possible effect is the change of the forest composition. [21] Deforestation can also cause forests to become more fire prone through mechanisms such as logging. [22]
Yet deforestation increased by 4% worldwide in 2022 compared with 2021, as s. The world is moving too slowly to meet pledges to end deforestation by 2030, with the destruction worsening in 2022 ...
One result is that shifting cultivation is not the primary cause of deforestation in all world regions, while transport extension (including the construction of new roads) is the largest single proximate factor responsible for deforestation. [19] Habitat size and numbers of species are systematically related.
Drivers of deforestation and forest degradation by region, 2000–2010, from the Food and Agriculture Organization publication The State of the World's Forests 2020. Forests, biodiversity and people – In brief [3] Deforestation is much worse than forest degradation, but it is clear and visible.
25-50% of the rainfall in the Amazon basin comes from the forest, and if deforestation reaches 30-40% most of the Amazon basin will enter a permanent dry climate. [14] In another article published by Nature, it points out that tropical deforestation can lead to large reductions in observed precipitation. [15]
The direct causes of deforestation within the DRC are well understood and have been identified consistently by many sources. [2] [3] [9] The direct causes are as follows: 1) road infrastructure development, 2) slashing and burning the forests to transform forest land into agricultural land, 3) the collection of fuelwood and charcoal, and lastly 4) unregulated artisanal and small-scale logging.
