The impact of climate change and human activities on desertification are exemplified in the Sahel region of Africa. The region is characterized by a dry hot climate, high temperatures and low rainfall (100–600 mm per year). [44] So, droughts are the rule in the Sahel region. [45]
Desertification in Africa is exacerbated by human factors such as deforestation, overgrazing, and unsustainable farming methods such as monoculture and excessive use of chemical fertilizers. For example, deforestation reduces the quantity of plants that may anchor soil and protect it from erosion, whereas overgrazing depletes vegetation and ...
Desertification is one of the issues of environmental concern in Nigeria, particularly the northern part of the country. According to UNEP [4] in 1993, Northern Nigeria has one of the highest rates of deforestation in the world at about 3.5%, caused by land degradation, increase in agricultural intensity, over-grazing of livestock, and demand for fuel by cutting down trees.
At least 90% of Mongolia's pastureland has experienced some level of desertification. [3] Between 1996 and 2009 up to a third of rivers dried out or were impacted by drought conditions. [3] It has been found that desertification is predominantly (approximately 87%) caused by human factors rather than natural factors.
Deforestation leads to desertification, ecosystem and biodiversity loss, land degradation, increased greenhouse gases, and soil erosion, significantly impacting the environment and human well-being [26] Deforestation threatens the sustainability of the environment, which in turn may lead to risks for citizens' quality of life due to economic ...
In Ghana, deforestation is mostly done for commercial benefit, frequently with little consideration for the effects on the environment. In addition, the growth of human populations associated with urbanization leads to the devastation of forest vegetation to provide space for infrastructure and houses. [18] Consequently, deforestation, largely ...
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.
The UNDP report on climate change in Yemen, desertification is a major environmental issue intensified by climate change and human activities. The country faces severe droughts, unpredictable rainfall, and higher temperatures, all contributing to the degradation of arid and semi-arid land that makes up over 90% of its territory.
