    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.

    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.

    Pastoral mobility is seen as the most effective strategy to make use of constantly shifting resources. However, mobile pastoralism as a highly-valued strategy to manage grazing areas and exploit resource variability is becoming more complex, due to recurrent droughts, loss of forage, government-led settlement schemes, and enclosure of land for community conservation, among other reasons. Yet knowledge of how Samburu pastoralists perceive these changes, and govern and innovate in their mobility patterns and resource use, has received limited attention.

    Kenya, Afrique orientale

    Rangelands throughout sub-Saharan Africa are currently undergoing two major pressures: climate change (through altered rainfall and seasonality patterns) and habitat fragmentation (brought by land use change driven by land demand for agriculture and conservation). Here we explore these dimensions, investigating the impact of land use change decisions, by pastoralists in southern Kenya rangelands, on human well-being and animal densities using an agent-based model.
