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 ...
The livelihoods of millions of people and species are at risk with deforestation. The act is a domino effect that affects multiple aspects of a community, ecosystem, and economy. [9] Many African nations have begun to implement restoration projects to reverse the effects of deforestation.
The Gobi desert continues to expand northward, with over 70% of Mongolia's land degraded through overgrazing, deforestation, and climate change. [64] In addition, the Mongolia government has listed forest fires , blights , unsustainable forestry and mining activities as leading causes of desertification in the country. [ 65 ]
A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
A 10.3 million km2 area, or 34.2% of the continent's surface, is at risk of desertification. If the deserts (Sahara and Kalahari) are taken into account, the affected and potentially affected area is roughly 16.5 million km2 or 54.6% of all of Africa. 5.7 percent of the continent's surface is made up of very severe regions, 16.2 percent by ...
In a forest resource assessment of Ethiopia, Reusing found that within 17 years (1973–1990) high-forest cover decreased from 54,410 to 45,055 km² or from 4.72 to 3.96% of the land area. [5] He calculated a deforestation rate of 1,630 km² per year, which means that deforestation at the same rate would leave about 18,975 of the 45,055 km² in ...
Urbanization, expansion of agriculture, and energy consumption contribute to deforestation. Wood is the primary natural resource used in local communities. Studies show that wood is often used inefficiently by people living in rural, traditional housing. [14] Saudi Arabia's growing population increases food insecurity. In turn, forests are ...
Deforestation in the Democratic Republic of the Congo has been caused partly by unregulated logging and mining, but mostly by the demands made by the subsistence activities of a poor population. In the east of the country, for example, more than 3 million people live less than a day's walk from Virunga National Park. Wood from the park's ...
