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.
Experts say soil acidity causes land degradation by decreasing the availability of plant and essential nutrients, making soil more vulnerable to structure decline and erosion.
As a result, they are suffering heavily, especially through land degradation — such as the loss of vegetation cover due to overgrazing or the loss of key species due to pollution, agriculture or ...
Restoring the world's degraded land and holding back its deserts will require at least $2.6 trillion in investment by the end of the decade, the U.N. executive overseeing global talks on the issue ...
Desertification in Africa is a form of land degradation that involves the conversion of productive land into desert or arid areas.

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 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]
At the beginning of the 20th century, around 420,000 km 2 (160,000 sq mi) or 35% of Ethiopia's land was covered with forests. Recent reports indicate that forests now cover less than 14.2% [ 25 ] or even only 11.9% as of 2005 [update] . [ 27 ]
