According to Global Assessment of Land Degradation and Improvement (GLADA) a quarter of land area around the globe can now be marked as degraded. Land degradation is supposed to influence lives of 1.5 billion people and 15 billion tons of fertile soil is lost every year due to anthropogenic activities and climate change. [29]
Overgrazing by livestock can lead to land degradation. Land degradation is a process where land becomes less healthy and productive due to a combination of human activities or natural conditions. The causes for land degradation are numerous and complex. [1] Human activities are often the main cause, such as unsustainable land management practices.
Land degradation in Somalia is becoming an increasingly important issue as approximately one-third of Somalia's arable land has degraded and lost its fertility. [1] Land degradation in Somalia comes in a few major forms including soil erosion, loss of topsoil, the loss of vegetation due to overgrazing, and loss of vegetation due to the cutting of trees for the production of charcoal or for the ...
Water and wind erosion are now the two primary causes of land degradation; combined, they are responsible for 84% of degraded acreage. [2] Each year, about 75 billion tons of soil is eroded from the land—a rate that is about 13–40 times as fast as the natural rate of erosion. [78]
Overgrazing typically increases soil erosion. [7]With continued overutilization of land for grazing, there is an increase in degradation. This leads to poor soil conditions that only xeric and early successional species can tolerate. [8]

Land degradation frequently leads to less stabilization of soil by vegetation. [8] Additionally, global warming caused by climate change and other human impact on the environment, can increase the frequency of natural events (such as extreme weather) which trigger landslides. [9]
Human land development, in forms including agricultural and urban development, is considered a significant factor in erosion and sediment transport, which aggravate food insecurity. [70] In Taiwan, increases in sediment load in the northern, central, and southern regions of the island can be tracked with the timeline of development for each ...
