    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

    Land Use and Land Cover Change (LULCC) is the most prominent cause of Soil Organic Carbon (SOC) variability in any landscape. Kenyan Arid and Semi-Arid Lands (ASALs) have been facing extensive land use/ cover changes in the last three decades prompting a review on the impacts it has on soil quality and consequently on land degradation. This study was carried out in 2016 in Olesharo Catchment, Narok County, one of the prominent ASALs of Kenya.

    Coastal Kenya is a food deficit area producing only 20 percent of its
    food requirement and is referred to as a net importer of food.
    However, technologies that can improve food production in the area
    exist and continue being developed. These technologies include:
    deep tillage, timely planting, use of green manure, animal manure •
    and fertilizer application.
    Social capital refers to the various social relationships and networks
    and the resources that become available thereof. Adoption has to do

    There is correlation on land degradation in reference to environment conflict against natural
    resources undocumented. Environmental conflicts mostly depend over human needs and issues
    such as distribution, allocation and natural resources management. History documents show how
    resource-based conflicts had contributed to highly destructive wars at Karamoja and Kagera
    regions of Uganda, Darfur in Sudan, in Rwanda genocide and even in the Niger Delta. Mau
    Forest Complex is Kenya’s important water tower. Important rivers that deplete in to Lake

    Region:East Africa.Focus:A review of catchment studies (n = 37) conducted in East Africa evaluating the impacts ofLand Use and Land Cover Changes (LULCC) on discharge, surface runoff, and lowflows.New hydrological insights:Forest cover loss is accompanied by increased stream discharges andsurface runoff. No significant difference in stream discharge is observed between bamboo andpine plantation catchments, and between cultivated and tea plantation catchments.

    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.
