Many factors can hold roles that would lead to the increase size of the Sahara, but the most drastic remain severe droughts that are common to the area and the natural winds of the desert that pushed the desert-like conditions further south by, at one point, an annual rate of 30 miles, destroying land that was once vital for the agriculture of neighbouring communities and nations. What once was a land that people would be able to conquer with nomadic lifestyles to travel through certain routes, has become far too massive to allow many of these people to continue this form of life. Not much can be done to fight this desertification but African nations begun to take the biggest steps possible by attempting to increase sustainable land usage and, by some means, drought resiliency.
Desertification has been a two-way thing by how it has been increasing in size.There are some areas where the issue has been solely based on high usage of land for agriculture. This high amount of soil degradation has caused dryland conditions to arise in areas south of the equator in Africa. This is all while in other areas the desert’s quick expansion has become the oil cause of loss of food producing land and pushing people away from their dwellings as the desert conditions expand. Another issue has been low-proficiency irrigation programs, like ones for the Lake Chad, that have brought a huge loss of a water source, and expanding desert conditions even more. What has become a surprise is the effect that climate change has on the expansion of the African desert, the Sahara.
After realizing the high expansion rate of the desert, one might think that the Sahara will be a desert that destroys the lands and lives of millions, but this is not necessarily the case. Climate changes have been bringing frequent rains to the edges of the Sahara, causing a greening of the desert’s edges. With the rains becoming much more common, it will become possible that land will be revitalized and available for the farming communities that once settled in those regions. The connotation for climate change is typically a negative one, but with regards to the Sahara desert, it is a positive occurrence. The millions living near the hot sand could possibly thrive in population and lifestyle by how green the desert can get. The even better part of this, it’s been a continued trend for more than 20 years, giving hope that the hottest, deadliest desert in the world, will be holding a lot a more life than it has in past decades.
