    Southwestern Nigeria is replete with soils that have high gravel contents within the subsoils. Most of these soils are being opened up for cultivation as other land uses (roads and housing) are competing for agricultural lands. It is imperative that these soils be properly studied and managed to prevent serious land degradation, which may over the long term militate against food production in most rural communities.

    Land degradation in the Little Karoo is extensive. Overstocking of breeding ostriches on natural veld has been among the main causes of this. The National Department of Agriculture has set a general stocking rate of 60 ha LSU ⁻¹ as a guideline for livestock on natural veld in the Little Karoo, which equates to 22.8 ha ostrich ⁻¹.

    In sub-Saharan Africa, natural vegetation is being transformed into agricultural lands at a fast rate, endangering ecosystem services and increasing soil-loss potential, which may trigger land degradation. For the Taita Hills study area in Kenya, multi-temporal land-cover models of 1987, 1999 and 2003, derived from Satellite Pour l'Observation de la Terre (SPOT) imagery using a multi-scale segmentation/object relationship modelling (MSS/ORM) methodology and a rainfall layer, a digital elevation model (DEM) and a digital soil map were applied to model potential soil loss.
