The land and its natural resources (earth, water, plants and wildlife) provide food, water, firewood, medicinal plants and other ecosystem services. The soils regulate the carbon cycle and other biophysical processes. The land provides its populations with security, status and social identity. However, across the planet, land degradation affected 100 million hectares (twice the surface area of Greenland) every year between 2015 and 2019. If this trend continues, 1.5 billion hectares of land will need to be restored by 2030 in order to reach neutrality in terms of land degradation. Conducive to poverty and famine, this situation particularly impacts the 1.5 billion people living in the arid, semi-arid and dry sub-humid areas that cover 40% of the planet's land mass.
