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 ...
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.
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.
Large portions of the continent may become uninhabitable as a result of the rapid effects of climate change, which would have disastrous effects on human health, food security, and poverty. [41] [42] [43] Regional effects on rainfall in the tropics are expected to be much more spatially variable. The direction of change at any one location is ...
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 ...
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 ...
The environmental impact of irrigation includes the changes in quantity and quality of soil and water as a result of irrigation and the ensuing effects on natural and social conditions at the tail-end and downstream of the irrigation scheme. The impacts stem from the changed hydrological conditions owing to the installation and operation of the ...
