Drylands are highly vulnerable to natural and human destruction, due to the low water content of the soil (UNCCD, 2014).

About one third of all global agricultural land is either highly or moderately degraded. Australia was the first country to establish a national drought policy, and though other countries (Kiribati and Morocco) have made the first steps toward this, it remains one of the only countries to have a comprehensive drought management strategy.

In many dryland areas (INSERT SOME EXAMPLES), the climate is become even more arid and rivers, lakes and underground water sources are drying up. With climate change, terrestrial biomes also adjust – through changes in their range and species composition. This can have major impacts not only on physical processes (such as the water cycle), but also on ecosystem functions. In terms of global populations, these changes also mean that food-production zones are shifting, and in many regions crops and livestock are failing.

Desertification is a form of land degradation by which land becomes more arid. It’s definition is debated, but it generally refers to “the process of fertile land transforming into desert typically as a result of deforestation, drought, or improper/inappropriate agriculture” (Princeton University Dictionary). This process usually results in the desertified land losing its vegetation, water bodies (lakes, streams), and wildlife.

The primary cause of desertification is the removal of vegetation. This causes removal of nutrients from the soil, making land infertile and unusable for arable farming. The reason for the initial removal of vegetation varies, but the two dominant reasons are:
