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.
Sustainable Development Goal 15 (SDG 15 or Global Goal 15) is about "Life on land".One of the 17 Sustainable Development Goals established by the United Nations in 2015, the official wording is: "Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss".

Soil sealing or soil surface sealing is the loss of soil resources due to the covering of land for housing, roads or other construction work. [1] Covering or replacing the topsoil with impervious materials like asphalt and cement as a result of urban development and infrastructure construction paired with compaction of the underlying soil layers results in the mostly irreversible loss of ...
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 ...
In total, one-third of the world's population lives in drylands where land degradation is reducing food supplies, biodiversity, water quality and soil fertility. [ 2 ] The bioreclamation of degraded lands (BDL) system was developed by the International Crops Research Institute for the Semi-Arid Tropics ( ICRISAT ), with the aim of helping ...
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".

Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste .
The result is less labor and lower costs that increase farmers’ profits. No-till farming and cover crops act as sinks for nitrogen and other nutrients. This increases the amount of soil organic matter. [8] Repeated plowing/tilling degrades soil, killing its beneficial fungi and earthworms.
