Desertification is a gradual process of increased soil aridity.Desertification has been defined in the text of the United Nations Convention to Combat Desertification (UNCCD) as "land degradation in arid, semi-arid and dry sub-humid regions resulting from various factors, including climatic variations and human activities."
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.
The causes of both drought and desertification are multifaceted and intricate, stemming primarily from the intricate interplay between climatic factors and human activities in the environment. These causes encompass: Climatic Variability: Climatic variations serve as a significant catalyst for numerous environmental degradation issues ...
Long-term drought in Nigeria has resulted in desertification and a shortage of land for raising cattle and growing crops. [1] To obtain land for farming or grazing, farmers and herdsmen are encouraged to go to new areas, which frequently leads to violence [2] [3] [4] Herdsmen and farmers have been engaged in increasingly violent fights over the previous two years.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
In a similar vein, the research by Cai et al. (2020) [17] presents a stark example of the terrestrial impact of overgrazing, showing how the fertile island effect collapses under extreme conditions in shrub-encroached grasslands. This case study emphasizes the critical need for sustainable grazing practices to protect soil health and maintain ...
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.
