The Africa Soil Information Service (AfSIS) is developing a practical, timely, and cost-effective soil health surveillance service to map soil conditions, set a baseline for monitoring changes, and provide options for improved soil and land management. Because knowledge about the condition and trend of African soils is highly fragmented and dated, there is an urgent need for accurate, up-to-date, and spatially referenced soil information to support agriculture in Africa. This coincides with developments in technologies that allow for accurate collection and prediction of soil properties.
