    Characterizing soil erosion hazard and its spatial variability is critical for maintaining
    user confidence in planning soil- and water- conservation programmes and general
    land-use management. Predicting the average rates of soil erosion for a combination
    of specific soil and land-use types is vital. This is because such predictions form a
    basis for providing guidelines for effective erosion control.
    The purpose of this investigation was to examine the erosion effects of alternative

    Kenya

    For millenia, Greater Amboseli ecosystem of Kenya has had a central role in subsistence
    pastoralism and wildlife conservation by providing vast biological resources for pastoralists and
    their livestock; and habitat for wildlife. Recently, with the creation of Amboseli National Park
    and rapid changes in land tenure systems, the human use of the ecosystem has intensified. This
    change has shaped a pastoral landscape composed of livestock grazing, wildlife conservation,

    Kenya

    Preliminary findings on the effects of land use in the Masinga Dam catchment, Kenya, on the storage capacity of the reservoir are presented. Remote sensing and GIS techniques, supplemented with ground reports, were used to determine areas most susceptible to erosion. A representative catchment was then chosen for rainy season monitoring of soil loss, river suspended sediments and discharge response to rainfall. In addition, Gerlach-type traps were used to evaluate erosion rates under different crop covers and slope gradients.
