At the European Development Days, EuropeAid hosted a Lab session dedicated to the relevance of soils in development policy, featuring the release earlier this year of the first Soil Atlas of Africa.

In many places, it can take up to 2000 years to create a mere 10 centimetres of fertile soil, which can be washed or blown away in a matter of hours in a severe storm, or depleted in a few years of poorly managed land and water use.
