The Dominican Center for Agricultural and Forest Development [7] lists the following causes of forest degradation: Excessive extraction of forest products like timber, charcoal or resin. Road building : after it has been built, the road favours soil erosion .
This causes a cycle as floods can degrade soil, and soil degradation can cause floods. Deterioration of the water quality: the increase in the turbidity of water and the contribution of nitrogen and of phosphorus can result in eutrophication.
The rising demand for certain products and global trade arrangements causes forest conversions, which ultimately leads to soil erosion. [91] The top soil oftentimes erodes after forests are cleared which leads to sediment increase in rivers and streams. Anthropogenic biomes of the world. Most deforestation also occurs in tropical regions.
Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, and animals (including humans).
The typical tropical forest may become a carbon source by the 2060s. [46] Researchers have found that, in terms of environmental services, it is better to avoid deforestation than to allow for deforestation to subsequently reforest, as the latter leads to irreversible effects in terms of biodiversity loss and soil degradation.

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.
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. [2]
Third, the deforestation of tropical forests is leading to land degradation. When forests are cleared, the soil is often left exposed to erosion. This can lead to land degradation, which can make it difficult to grow crops. The deforestation of tropical forests for fruit production is a serious problem with a number of negative environmental ...
