This degradation makes the forest less valuable and may lead to deforestation. Forest degradation is a type of the more general issue of land degradation. Deforestation and forest degradation continue to take place at alarming rates, which contributes significantly to the ongoing loss of biodiversity. [2]
It was superseded by REDD+ in the Warsaw Framework on REDD-plus negotiations.Since 2000, various studies estimate that land use change, including deforestation and forest degradation, accounts for 12–29% of global greenhouse gas emissions.
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 ...
Forest cover in the Eastern United States reached its lowest point in roughly 1872 with about 48 percent compared to the amount of forest cover in 1620. The majority of deforestation took place prior to 1910 with the Forest Service reporting the minimum forestation as 721,000,000 acres (2,920,000 km 2) around 1920. [2]
As an example, forest degradation may have a reference emission level for commercial selective logging and one for extraction of minor timber and firewood for subsistence use by rural communities. Effectively, every identified driver of deforestation or forest degradation has to be represented in one or more reference emission level(s).
Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.
Habitat degradation, fragmentation, and pollution are aspects of habitat destruction caused by humans that do not necessarily involve over destruction of habitat, yet result in habitat collapse. Desertification, deforestation, and coral reef degradation are specific types of habitat destruction for those areas (deserts, forests, coral reefs).
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]
