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's detrimental effects on ecosystems and biodiversity can have far-reaching consequences for industries like tourism and ecotourism, which rely on healthy ecosystems to attract tourists. Desertification has enormous economic ramifications in Africa, necessitating persistent efforts to minimize the effects of desertification ...
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.
Consequently, deforestation, largely driven by human activities, has played a significant role in the desertification of Ghana. [4] Climate change is a significant contributor to desertification in Ghana. [19] The country is especially susceptible since it relies heavily on rain-fed agriculture and has inadequate capacity for mitigation and ...
Humans play a role in desertification through ill-advised land utilization practices and the mounting pressure placed on finite resources due to population growth. Essentially, human-induced desertification is a result of the exploitation of "non-ideal lands," excessive resource exploitation, unsustainable practices, and the failure to replace ...
From climate change to species loss and pollution, humans have etched their impact on the Earth with such strength and permanence since the middle of the 20th century that a special team of ...
While the frequency of drought in the region is thought to have increased from the end of the 19th century, three long droughts have had dramatic environmental and societal effects upon the Sahel nations. Famine followed severe droughts in the 1910s, the 1940s, and the 1960s, 1970s and 1980s, although a partial recovery occurred from 1975-80.
