Desertification is the term you are looking for.
If animals keep overgrazing in the savanna, it can lead to depletion of vegetation, soil erosion, loss of biodiversity, and disruption of the ecosystem's balance. This can ultimately result in desertification and a decline in the overall health and productivity of the savanna ecosystem.
Improper farming and irrigation practices are causing desertification in Mexico.
Desertification :D
The desertification of the Sahara, which intensified during the Holocene period, forced many communities to migrate southward into the more hospitable savanna regions in search of water and arable land. This migration led to the establishment of new settlements and agricultural practices in the savanna, facilitating cultural exchanges and the spread of technologies among different groups. Additionally, the movement contributed to the demographic shifts and social dynamics in the region, as populations adapted to the changing environment.
The answer is DESERTIFICATION
The Sahel is the ecoclimatic and biogeographic zone of transition in Africa between the Sahara desert to the north and the Sudanian Savanna to the south. It is arid land but not a true desert.
This process is known as desertification. It involves the degradation of land in arid, semi-arid, and dry sub-humid areas, leading to the transformation of fertile land into desert. Factors such as climate change, overgrazing, deforestation, and unsustainable agricultural practices contribute to this phenomenon.
The Sahel is a transition zone below the Sahara. It is a semiarid region. It has been rapidly become part of the Sahara due to a process called desertification.
The process is called desertification.
