   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

   The problem of vegetation degradation in Kenya's semi-arid areas must be addressed, if these areas are to support the increasing human and livestock population. However, efforts to rcvcgctatc denuded rangelands will be beneficial only if the right species and cultural practices arc employed.

   Climate change impacts livelihoods adversely in dry-lands of Northern Kenya in terms of longer and harsher droughts, shorter and intense precipitation and floods. Climate change interlocks with peoples life-worlds differently for different reasons. Understanding the foregoing can inform and make policy more relevant. What are the Samburu peoples discernment of climate change and how have they confronted it? The paper examines the Samburu perspectives of climate change and the resulting coping, adaptation mechanisms and practice, and their prospects.

   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. A modified-Whittaker sampling design was used to collect soil
   and pasture samples in three land cover types (bare, herbaceous and woody) under three

   A study on factors affecting honey production and indigenous knowledge of the Kibwezi Communities
   in honey production was conducted using formal and informal interviews by questionnaires between January and
   Sepicmber, 199). Honey plants were determined using pollen analysis, field observation and indigenous
   knowledge. Botanical composition of trees and shrubs in unsettled University of Nairobi site and adjacent settled
   area was determined and data ana lysed for density: frequency: diversity. similarity and dissimilarity indices.

   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

   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.

   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
