The European Commission has presented the first Soil Atlas of Africa, highlighting a vital natural resource which provides food, fodder, fuel wood, reduces flood risk and protects water supplies.
With full colour maps and illustrations, the atlas explains in a simple and clear manner the diversity of soil across the African continent and emphasizes the importance of this non-renewable resource. Coordinated by the European Commission's in-house science service, the JRC, an internationally renowned group of soil scientists from Africa and Europe has contributed to this atlas. The aim is to raise awareness at all levels – from politicians to the general public - of the significance of soil to life in Africa.
Deserts and drylands comprise 60% of the land surface of the African continent, populated by over one billion people. Much of the remaining land shows old, highly weathered soils which require special attention to be of use for agriculture. Population growth and urbanisation, coupled with conflicting economic challenges (cultivation of cash crops for export, biofuel production, biodiversity conservation, mineral extraction, carbon sequestration), increase the already heavy pressure on the land. Fertile and productive soils are key to tackling hunger and are a particular challenge in Africa, where, in many parts, soils are losing nutrients faster than fertilisers can be added.
Informed decision making is currently limited by the scarcity of up to date data on the soil resources of Africa. The JRC, in collaboration with the FAO and African soil scientists, will launch a pan-African assessment on the state of soil resources at the forthcoming conference of the African Soil Science Society in Kenya (October 2013).
The Soil Atlas is a collaborative initiative of the European Union, the African Union and the Food and Agriculture Organization of the United Nations to support and encourage the sustainable use of soil resources in Africa and the Global Soil Partnership for Food Security.
The Atlas explains the origin and functions of soil, describes the different soil types and their relevance to both local and global issues. It also discusses the principal threats to soil and the steps being taken to protect soil resources.
