Abstract: The protection and the sustainable management of soil resources in Africa are of paramount importance, particularly in the context of the uncertain impact of climate change and the increase pressure of the human activities. This situation requires a demand for up-to-date and relevant soil information at regional and continental scales. To provide timely and reliable information on soils at these scales, low-resolution spaceborne remote sensing offers an ideal support. Through a review of multispectral, thermal infrared, passive and active microwave imaging we show that sensors help in the delineation of soils themselves, as well as in the assessment of some of their key properties and threats such as water and wind erosion, landsliding and salinisation. However remote sensing imagery for mapping soil can be problematic if applied alone and often requires the use of ancillary data and field observations. Remote sensing is shown as being complementary to digital soil mapping.
