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.
The United Nations' Intergovernmental Panel on Climate Change's (IPCC) Special Report on Climate Change and Land (SRCCL), also known as the "Special Report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems", [1] [2] is a landmark study from 2019 by 107 experts from 52 countries.

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 ...
Soil on degraded land is less resilient and crops grown on degraded soil produce lower yields. Land degradation also negatively influences global food security: in the next 25 years, global food production might drop by up to 12%. [8] This will lead to an increase in average food prices of up to 30%. [9]

Desertification is a gradual process of increased soil aridity.Desertification has been defined in the text of the United Nations Convention to Combat Desertification (UNCCD) as "land degradation in arid, semi-arid and dry sub-humid regions resulting from various factors, including climatic variations and human activities."
