Factors limiting productivity of overgrazed, semi-arid rangelands on the Njemps Flats, Kenya were investigated, conducting fertilization and irrigation experiments. Productivity was evaluated in terms of yield, vegetation quality and soil chemical
Water supply from the reservoir has transformed land use patterns on the Njemps Flats, providing for irrigated vegetable and cereal cultivation. No reliable sediment yield estimates were available prior to dam construction. This paper is based
information on the hydrological and erosional response of rilled hillslopes at Baringo. Implications of test results for design of conservation measures, and particularly the importance of ground vegetation, are discussed.
for the species in the area. This study has also revealed that semi-arid areas can support much higher proportions of woody vegetation than are usually reported.
