    Land degradation is a gradual, negative environmental process that is accelerated by human activities. Its gradual nature allows degradation to
    proceed unnoticed, thus reducing the likelihood of appropriate and timely control action. Presently, there are few practical frameworks to help
    countries design national strategies and policies for its control. The study presented here developed a framework for the national assessment of
    land degradation. This framework is envisaged to support governments in formulating policies on land degradation. It uses time-series remote

    Rehabilitating degraded rangelands using enclosures offers various benefits to agro-pastoral households. However, enclosure benefits cannot be generalized as there are variations across dryland ecosystems and societies. This study assessed the qualitative and quantitative benefits derived from rehabilitating degraded rangelands using private enclosures in Chepareria, West Pokot County, Kenya.

    Natural disasters disrupt people's lives through displacements, destruction of livelihoods and property, deaths, and injuries. Consequently, they take back years of development, thus posing a major challenge to the achievement of the Millennium Development Goals especially the target of halving extreme poverty by 2015 and Kenya's set development goals as contained in Vision 2030.

    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 objective of the study was to detect and identify land cover changes in Laikipia County of Kenya that have occurred during the last three decades. The land use types of study area are six, of which three are the main and the other three are the minor. The main three, forest, shrub or bush land and grassland, changed during the period, of which grasslands reduced by 5864 ha (40%), forest by 3071 ha (24%) and shrub and bush land increased by 8912 ha (43%).

    This study aims to document various community efforts in land rehabilitation and assess their potential. Data were captured using interviews and focus group with 150 community members. A public participation index was used to establish the extent of community efforts in land rehabilitation. The study revealed that in the absence of proper management and dune stabilisation, large areas covered with mobile sand dunes continue to be a threat to grazing lands in northern Kenya. In recognition of this threat, the people of North Horr have launched several initiatives to contain the problem.

    Most early alley cropping studies in semi-arid Kenya were on fairly flat land while there is an increase in cultivated sloping land. The effectiveness of aging contour hedgerows and grass strips for erosion control on an about 15% slope of an Alfisol was compared. The five treatments were Senna siamea hedgerows with tree prunings applied as mulch to crops (H + M), hedgerows with crops with prunings removed (H), mulch only applied to crops (M), crops with Panicum maximum grass strips (G), and a sole crop control of a rotation of maize (Zea mays) and cowpea (Vigna unguiculata).

    The area northwest of Mt Kenya is undergoing rapid land use changes caused by a population influx. Rapid population growth and subsequent pressure on land raise the problem of how to increase and sustain agricultural production while at the same time conserving the natural resources (montane forest with Olea africana and Juniperus procera as main species at 2900 m asl.). Deterioration in soil physical and chemical properties following deforestation for agriculture can adversely affect crop production, especially from soils on mountain slopes.

    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.

    Makueni District has experienced low crop production per unit area despite increased hectarage under crop
    production. The district relies heavily on farming for food and income generating activities for the households.
    However, poverty level has been on the increase due to poor crop production and limited diversity in sources of
    income. Analysis of field survey carried in the district shows high variability of soil nutrients (Nitrogen,
    Phosphorous, and potassium), Cation Exchange Capacity (CEC) and soil pH due to various land use systems
