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]
The degradation of forest ecosystems has also been traced to economic incentives that make forest conversion appear more profitable than forest conservation. [125] Many important forest functions have no markets, and hence, no economic value that is readily apparent to the forests' owners or the communities that rely on forests for their well ...
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]
Geist and Lambin (2002) assessed 152 case studies of net losses of tropical forest cover to determine any patterns in the proximate and underlying causes of tropical deforestation. Their results, yielded as percentages of the case studies in which each parameter was a significant factor, provide a quantitative prioritization of which proximate ...
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.
The forest resources of the United States remained relatively constant through the 20th century. [3] The Forest Service reported total forestation as 766,000,000 acres (3,100,000 km 2) in 2012. [4] [5] [3] A 2017 study estimated 3 percent loss of forest between 1992 and 2001. [6]
When natural habitats are destroyed or natural resources are depleted, the environment is degraded; direct environmental degradation, such as deforestation, which is readily visible; this can be caused by more indirect process, such as the build up of plastic pollution over time or the buildup of greenhouse gases that causes tipping points in ...
Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment [3] (suspected of being one of the major causes of speciation [3]), and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species.
