The Africa Soil Information Service is continuing with their plans to develop an “interactive, web-accessible digital soil map”, outlined in a previous blog article. This map will cover all the non-desert areas of Sub-Saharan Africa and is to be completed by the end of 2013. More recently, the European Commission’s Joint Research Centre has commissioned and launched, at the meeting of the African Union (AU) and EU commissions in April 2013, the first ever comprehensive map of African soils.
The Soil Atlas of Africa aims to increase African countries’ understanding of the diversity of soils found on the continent, the importance in managing this key resource and to aid governments in strategically planning land use and investments in agriculture and urban development.
The project started four years ago and is a collaboration between experts at the European commission, the AU and the UN Food and Agriculture Organisation (FAO). Already the map has helped identify areas, in central Africa, some parts of West Africa, and southern Africa where soil is particularly fertile. Experts working on the project also hope it will strengthen government support for national soil bureaus and for training users of the Atlas at the regional level.
Declining soil fertility and soil loss is a significant problem in Africa. Nearly 3.3% of agricultural GDP is lost in sub-Saharan Africa each year due to soil and nutrient loss while more than 75% of total land in the area has degraded or highly degraded soil. The Atlas will help to identify trouble zones so that plans for the sustainable use of soil can be put in place.
