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 caused by both natural and man-made forces. Climate change, which has resulted in increased aridity and decreasing rainfall in many regions, and soil erosion, which happens naturally but can be exacerbated by human activity, are the principal natural elements that lead to desertification. [18]
Nigeria has an estimated population of 113 million where human activities continues to take its toll on the environment, which ultimately results in desertification. [2] Desertification gets severe in the drylands of the country with increase in human attempts to exploit the resources of the ecological zone in the face of persistent drought. [3]
Human activities have substantial impact on coral reefs, contributing to their worldwide decline. [147] Damaging activities encompass coral mining, pollution (both organic and non-organic), overfishing, blast fishing, as well as the excavation of canals and access points to islands and bays.
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 ...
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 ...
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.
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 ...
