    Large-scale land acquisitions have increased in scale and pace due to changes in commodity markets, agricultural investment strategies, land prices, and a range of other policy and market forces. The areas most affected are the global “commons” – lands that local people traditionally use collectively — including much of the world’s forests, wetlands, and rangelands. In some cases land acquisition occurs with environmental objectives in sight – including the setting aside of land as protected areas for biodiversity conservation.

    Few regions present bigger development challenges than the African drylands – home to nearly 300 million people, and the vast majority of Africa’s poor. Food security and rural welfare in these areas are limited by a range of factors, biophysical, socio-economic and policy-related. And many of the biggest challenges – poverty, drought, land degradation, food insecurity – will be exacerbated by climate change.

    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

    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.

    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
