    The adoption and adaptation of enclosures in the arid and semi-arid rangelands of sub-Saharan Africa is driven and
    sustained by a combination of factors. However, reviews indicate that these factors cannot be generalized, as they
    tend to be case specific. A study was therefore conducted to explore the history and reasons for enclosure establishment
    in Chepareria, a formerly degraded communal rangeland in north-western Kenya. While Vi-Agroforestry Organization
    accounting for 52.5 % was the main source of knowledge on enclosure establishment; it has now emerged

    A study was conducted in dry and wet season to determine macro and micro mineral status of
    growing sheep and goats in arid rangelands of northern Kenya. Forty four, 22 each of sheep and goats (1-2
    year old), randomly purchased from three herds/flocks in study area, were sacrificed for whole liver and 12th
    right and left ribs. Homogenized liver samples pooled from all the lobes and defatted bone ash from whole
    left and right 12th ribs were used for determination of Ca, P, Mg, Cu, Fe, Zn and Mn status. Liver mineral

    Livestock production is the main source of livelihood in the arid and semi-arid lands in Africa. However, desertification characterized by vegetation degradation and soil erosion is a major threat to the sustainability of land-based production systems. Native rangeland forage species Cenchrus ciliaris L. (Buffel grass/African foxtail grass), Eragrostis superba Peyr. (Maasai love grass) and Enteropogon macrostachyus (Hochst. Ex A. Rich.) Monro ex Benth. (Bush rye grass) have been used to combat desertification.

    This study determined the patterns and magnitudes of land cover
    and use changes, their driving factors and impacts on soil quality
    and pasture productivity in Nakasongola district. Satellite data
    (1970 - 2009), surveys, soil and pasture sampling techniques
    were used. Woody and bare encroachments are major changes
    affecting soil quality and pasture productivity. Changes in fire
    regimes, poor stocking densities, termites, climatic variability
    and tree cutting are major drivers of the land cover and use

    This study evaluated the effects of holistic grazing management (HGM) on biomass production and soil properties under holistic and non-holistic grazing sites. The study was conducted in two Group Ranches namely, Koija and Il Motiok in Naibunga Conservancy, Laikipia County, Kenya. Vegetation attributes and soil parameters were determined in four plots randomly sited and established within the Il Motiok Ranch, which is under HGM, and in the same number of plots sited and established in Koija Ranch which is under free-range grazing system.

    study to characterize existing adaptive strategies and shifts in smallholder agro-pastoralists in relation to changes in land use and land subdivisions was carried out. A total of 48.9% of respondent indicated that there had been a shift in the adaptive strategies where unreliable rainfall, better access to land and water, acquisition of skills, shortage of pastures and proximity to wildlife habitats were the main factors influencing the shifts.

    Rangelands in semi-arid Kenya have recently witnessed extensive land use changes. These changes can mainly be attributed to increased livestock populations and the response of the increased human population to both local and exogenous opportunities and constraints. This study was carried out in Kibwezi district of Kenya mainly inhabited by agro-pastoralists. The main objective of this study was to establish how different land use types influence soil properties in tropical semi-arid rangelands.

    The impact of land use and cover change on soil quality and pasture production was investigated in the rangelands of Nakasongola District, Uganda. Landsat (TM) images of 1986 and 1990 and Landsat (ETM+) of 2000 and 2004 for Nakasongola District were used to determine the extent and patterns of land use and cover change using the Integrated Land and Water Information Systems (ILWIS) 3.6 software.

    Pastoralists traditionally relied on herd mobility to cope with drought. In the pastoral areas of Kajiado,
    Kenya this strategy is now threatened by increased individual land ownership as compared to
    communal access. Drought frequency as related to El-Nino and Southern Oscillation (ENSO) is
    predicated to increase with climate change. The aim of the study was investigate the use of herd
    mobility strategy in the ENSO related 1999/2000 la Nina induced drought under different land tenure

    The study discusses land-degradation in pastoral communities and depicts land-use system and associated human and livestock population pressure as the major determinant of vegetation cover, surface run-off, soil erosion, and species richness. The study recommends use of enclosures to reverse range degradation, and diversification of pastoral economies to reduce poverty and relieve pressure on land as the primary source of livelihood in the semi-arid rangelands of Kenya
