    The distribution of Trichoderma species in soils of Embu region in relation to land use practices was investigated. The study area was chosen because of its significant land use intensification. Soil washing and dilution plate techniques were used to recover Trichoderma spp from the soil samples. The fungal isolates were identified and assigned to eight species. Greater populations as well as a wider range of species were obtained in soils collected from the natural forests while coffee farms were the poorest ones. Land use affected the distribution of Trichoderma.

    Coastal Kenya is a food deficit area producing only 20 percent of its
    food requirement and is referred to as a net importer of food.
    However, technologies that can improve food production in the area
    exist and continue being developed. These technologies include:
    deep tillage, timely planting, use of green manure, animal manure •
    and fertilizer application.
    Social capital refers to the various social relationships and networks
    and the resources that become available thereof. Adoption has to do

    Agriculture is the backbone of the Kenyan economy contributing 26% to GDP and 70% to
    employment. Majority of the farmers in Kenya are smallholder farmers possessing less than 3
    acres of land. The agricultural sector in Kenya has been facing several challenges among them
    declining yields. While the decline in yields could be associated with several other factors, it
    could also be as a result of the effect of insecure land tenure systems which are little understood.
    This study examines the technical efficiency of alternative land tenure systems among

    Hedged agroforestry (AF) demonstration plots with maize/bean intercrops were studied at Matanya in
    Laikipia district, Kenya, between 1991 and 1995 inclusive, to understand crop yield behaviour due to
    selected soil moisture conservation methods applicable in semi-arid areas. The treatments were:
    Grevillea robusta trees root pruned, compared to unpruned, both in combination with (1) minimum
    tillage and mulching with 3t/ha maize stalks harvested from the plots with additional stalks collected

    Land conservation technologies used by farmers are known to play an important role in improving farm incomes and household welfare in the long run. For this reason substantial investments have been made in research to improve agricultural technologies in various parts of the world, from the development of new crop varieties to new practices of land management. This paper explores the impact of land rights among other factors on adoption of soil and water conservation practices.

    This article is concerned with the hypothesis that devolution, understood as entrusting local government
    with significant domains of autonomous discretionary power, will lead to the equitable and efficient management of
    natural resources. The paper focuses on the three domains of power conceived by some theorists as critical in the management
    of natural resources, namely making rules, implementing rules, and resolving disputes in relation to these rules.

    Women in most rural communities in Africa dominate farm activities in terms of labour
    supply and management. Overall, Africa's performance in terms of agricultural
    production and productivity remain inadequate and the region has failed to make progress
    in food security (Republic of Kenya, 2002). Therefore, successful agricultural reform
    programs will require raising women's productivity. The current study examines the
    existence of real evidence that women's limited access to land constitute a significant

    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).
