    When the Canadian company Bedford Biofuels (BB) started talks with local ranch owners in Tana Delta district (Kenya) about subleasing their land for a large jatropha plantation, they were not the first ones to come to the region for a large-scale agricultural project. Nor were they the first to explore the possibilities of starting a jatropha plantation in Kenya’s coastal area.

    Constrained access to land is increasingly recognized as a problem impeding rural household welfare in densely populated areas of Africa. This study utilizes household and plot level data from rural Kenya to explore the linkage between land access and food security. We find that a 10% increase in operated land size would increase total cereal consumption and home produced food consumption by 0.8% and 2.0%, respectively. We also find that land rental is the dominant mechanism that poor rural farmers use to access additional land for cultivation.

    Biodiversity in rangelands is decreasing, due to intense utilization
    for livestock production and conversion of rangeland into cropland;
    yet the outlook of rangeland biodiversity has not been
    considered in view of future global demand for food. Here we
    assess the impact of future livestock production on the global
    rangelands area and their biodiversity. First we formalized existing
    knowledge about livestock grazing impacts on biodiversity,
    expressed in mean species abundance (MSA) of the original

    The land question in many African countries has geographical, political, economic, social and demographic nuances. These factors color land and resource rights for pastoral and forest dwelling communities. Land as property draws from the universality of the theory of property in time and space with the earliest theoretical explanations of property being occupation of land and where property belonged of right to him who seized it first. Land therefore represents the earliest form of property and includes resources on the land such as trees; pasture; water and wetlands.

    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.

    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.

    Nitrogen (N) fixation was estimated for three Acacia senegal (L.) (A. senegal) Willd. varieties (A. senegal var. senegal, kerensis, and leiorhachis) growing naturally in different sites in the dryland areas of Kenya. The quantities of N2 fixed were estimated by the 15N natural abundance method, using leaves as the sampling material. Balanites aegyptiaca (B. aegyptiaca) was selected as the reference species growing in the same area. Soil samples were also collected under A. senegal trees for nodule assessment. Leaf 15N natural abundance values (δ15N) were significantly different between A.
