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.
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 ...
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."
Ecosystems are facing numerous threats due to human activities, such as deforestation, pollution, climate change, and habitat destruction (Millennium Ecosystem Assessment, 2005). These disturbances can disrupt the delicate balance of an ecosystem, leading to species extinction , loss of biodiversity , and the degradation of ecosystem services .
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 ...
Drought is a phenomenon that occurs in Nigeria and impacts the whole nation. The arid and semiarid regions are more sensitive than the dryer south, but the degree of vulnerability varies. In Northern Nigeria , there are several records of drought occurrences that resulted in famines in the years 1914, 1924, 1935, 1943, 1951–1954, 1972–1973 ...
The National Agency for the Great Green Wall (NAGGW) is a Nigerian federal agency under the Federal Ministry of Environment (Nigeria), established to address land degradation and desertification, boost food security and support communities to adapt to climate change in the Nigerian states of Sokoto, Kebbi, Kastina, Zamfara, Kano, Jigawa, Bauchi, Gombe, Yobe, Borno, and Adamawa.

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 ...
