Desertification is defined as land degradation occurring in the global drylands. It is one of the global problems targeted under the Sustainable Development Goals (SDG 15). The aim of this article is to review the history of desertification and to evaluate the scientific evidence for desertification spread and severity. First quantitative estimates of the global extent and severity of desertification were dramatic and resulted in the establishment of the UN Convention to Combat Desertification (UNCCD) in 1994. UNCCD’s task is to mitigate the negative impacts of desertification in drylands.

In the future scenario for livestock development, there is a continuing role for smallholder producers, particular for dairy and small ruminants, relying heavily on grass and crop-residues, however in a growth mode, intensifying production, and enhancing the efficiency of resource use (less land, labor and feed resources per unit product). In particular improving the efficiency of converting feed into milk and meat will be critical to increase their income.

Soil loss is not limited to change from forest or woodland to other land uses/covers. It may occur when there is agricultural land-use/cover modification or conversion. Soil loss may influence loss of carbon from the soil, hence implication on greenhouse gas emission. Changing land use could be considered actually or potentially successful in adapting to climate change, or may be considered maladaptation if it creates environmental degradation.
