	Desertification is mostly attributed to human activity and climate change. Climate change has led to an increase in extreme weather events such as droughts and forest fires, which both contribute heavily to desertification. [10] Climate change has also led to an increase in global temperatures. These warmer climates have increased rates of evaporation which speed up the process of desertification. [11] In addition, the expansion of agriculture and deforestation have decreased overall natural vegetation. Increased food demand due to population growth has led to the expansion of agriculture, which decreases vegetation through: overgrazing by livestock, improper use of fertilizers, and the irresponsible cultivation of land.

	One of the most controversial proposals comes from Allan Savory, founder of the Savory Institute. Savory proposes a holistic approach to reversing desertification - relying on, not avoiding, livestock to re-green. Savory theorizes that through proper management, agriculture can be employed in a way to mimic nature and farmers can use sustainable farming to prevent further degradation.[5]		One of the most controversial proposals comes from Allan Savory, founder of the Savory Institute.

	Desertification is a natural or human induced process in which fertile land becomes desert irreversibly. The resulting loss of plant life leads to a decrease in overall biological productivity.[1] Barren [[soil]] becomes more susceptible to erosion and increasingly vulnerable to evaporation and higher temperatures. The cause of this process is most often attributed to anthropogenic climate change, but a multitude of factors influence desertification. [2] Rapid desertification is expected to have drastic environmental, economic and political consequences. [[File:desertification map.PNG\|thumb\|alt=map\|Figure 1.

	Desertification has become an increasingly alarming problem in Nigeria. To combat the effects of desertification, a major project was launched in 2007 titled "The Great Green Wall". Through the efforts of this project it is hoped that over 8,000 km of greenery will be restored to Africa. What initially began as an idea to plant a wall of trees has slowly evolved over time to incorporate more of a mosaic approach. Aside from just planting trees the project aims to return to responsible land use. By 2030, organizers hope to restore 100 million hectares of degraded land, sequester 250 million tons of carbon and create 10 million jobs.

	Desertification is most attributable to human activity and climate change. According to scientists, poorly managed livestock herds has led to overgrazing of grasslands. In addition, the expansion of agriculture and deforestation have decreased overall natural vegetation. In turn, loss of vegetation has led to a host of problems resulting in the degradation of land. The change from fully grassed lands to scattered shrubbery leaves land bare and susceptible to erosion. Unprotected soil surfaces are also prone to salinization by evaporation and water logging. [3] Nutrients are washed away, fauna dies from lack of nutrients or washes away as well.
