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.
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 ...
Environmental mitigation refers to the process by which measures to avoid, minimise, or compensate for adverse impacts on the environment are applied. [1] In the context of planning processes like Environmental Impact Assessments, this process is often guided by applying conceptual frameworks like the "mitigation hierarchy" or "mitigation sequence".

Land management is the process of managing the use and development of land resources. One aim of sustainable land management is to prevent or reverse land degradation. Another aim is to ensure water security by increasing soil moisture availability, decreasing surface runoff, and decreasing soil erosion. [1]
The Society for Ecological Restoration defines restoration as "the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed." [1] Restoration ecology is the academic study of the science of restoration, whereas ecological restoration is the implementation by practitioners. [21]
This reduces the food security, which many countries facing soil degradation already do not have. [8] Slight degradation refers to land where yield potential has been reduced by 10%, moderate degradation refers to a yield decrease of 10–50%. Severely degraded soils have lost more than 50% of their potential.
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."
