All of these causes have contributed to the degradation of fertile soil, posing a serious threat to the livelihoods of millions of Africans who rely on the land for subsistence. In the Sahel, desertification is mostly attributed to wind erosion. [24] To put it simply, wind erosion is the phenomenon when a strong wind removes a field's topsoil.
The Sahel region is a climate zone sandwiched between the Sudanian Savanna to the south and the Sahara desert to the north, across West and Central Africa. 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 ...
Ghana, which is located in the Sahel region of West Africa, [5] has an arid and semi-arid climate, which makes it especially vulnerable to desertification and the negative consequences of climate change. [6] These environmental problems are further made worse by population pressure.
It was found that around 3,000 B.C., the Sahel averaged 650 millimetres of rainfall a year compared to an average of 350 millimetres recorded today. [25] Given the issue of desertification, even if Lake Chad was not directly a cause of the famine, its potential demise is expected to further aggravate the problem.
The Sahel region (brown), proposed Great Green Wall (green), and participating countries (white) Satellite photo of the Sahara The Great Green Wall or Great Green Wall for the Sahara and the Sahel (French: Grande Muraille Verte pour le Sahara et le Sahel; Arabic: السور الأخضر العظيم, romanized: as-Sūr al-ʾAkhḍar al-ʿAẓīm) is a project adopted by the African Union in ...
The Gobi desert continues to expand northward, with over 70% of Mongolia's land degraded through overgrazing, deforestation, and climate change. [64] In addition, the Mongolia government has listed forest fires, blights, unsustainable forestry and mining activities as leading causes of desertification in the country. [65]
Mali, Burkina Faso and Niger have formed the Confederation of Sahel States (AES) to reject Western pressures and establish a defense pact, signaling a shift in West Africa's geopolitical landscape ...
The Sahel has a high to very high sunshine duration year-round, between 2,400 hours (about 55% of the daylight hours) and 3,600 hours (more than 80% of the daylight hours). The sunshine duration in the Sahel approaches desert levels, and is comparable to that in the Arabian Desert, for example, even though the Sahel is only a steppe and not a ...
