    Land is a critical resource in Kenya, having economic, social, political,
    environmental and cultural significance. Kenya’s population continues to rely
    on land for both subsistence and economic activities. In fact, the increase
    of the population from about 20 million people in the 1960s to about 40
    million currently, has put enormous pressure on land. Only a third of Kenya’s
    land is arable while the rest is arid and semi-arid. With most Kenyans still
    living off the land, contestations over access to, control over and ownership

    This paper presents data on diversity and abundance of soil macrofauna of various land use systems in Embu, Kenya (natural forest, plantation forest, fallow, coffee, tea, napier, and maize). Each was sampled for macrofauna using three sampling methods (monolith,
    transect and pitfall traps). Thirty four (34) genera/species of soil macrofauna were recorded, the highest number (27) being observed in napier. Majority of these genera/species being Coleoptera. Rényi diversity profile indicated that in terms of

    transect and pitfall trapping). Seventy eight (78) genera/species were recorded across the different land use systems of Taita. Rényi diversity profile indicated no significant differences in species richness across land use systems as reflected by the very close

    Due to the increased concerns about the effect of agrochemicals
    on soil health and soil biodiversity, use of
    biological methods has become most acceptable
    alternative methods for farmers to control soil
    pathogens during crop production. A study was
    therefore undertaken to determine the occurrence of
    nematode destroying fungi in Taita Taveta with the
    aim of isolating and characterizing them for biological
    control of plant parasitic nematodes. Twenty eight
    fungal isolates, distributed in three genera, were

    This study was motivated by the need to understand the interplay
    between cotton farming in Barwessa and household food security
    in the area.
    The study was centered on three main objectives:
    • To examine the extent to which subsistence farming is affected by
    cotton,
    • To identify the relationship between levels of household food security
    in relation to income and expenditure,
    • To investigate women's access to income from cotton production, their
    food production and food security roles,

    There has been tremendous changes in soil use and management in the River Njoro Watershed during the last three decades. Formerly large-scale farms converted into smallholder farms and plantation forests have gradually been lost. These changes in soil use have brought in different soil use and management approaches that have triggered soil erosion and other forms of land degradation. Up to 8.6 Kg of soil, loss per hectare from the cultivated soils has reportedly been lost in one storm. This massive soil loss was probably due to reduced aggregate stability and hydraulic conductivity.

    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

    The study was undertaken to investigate how land use and soil fertility management practices affect the occurrence of nematode destroying fungi. The aim of the study was to harness the potential of these fungi to control the plant parasitic nematodes in the study area which is a very important vegetable catchment in the Coast Province of Kenya

    The elements of Land Administration in Kenya are very fragmented and independently operated
    within the Ministry of Lands. During institutional reform there is opportunity to provide a much
    more integrated Land Administration service to the citizens, especially at the district level
    through the formation of ‘one-stop-shops’, through the integration and rationalization of the
    existing land administration and land rights delivery systems.
    This project report highlights the benefits offered through the application of GIS in management

    The distribution of Trichoderma species in soils of
    Embu and Taita benchmark sites in Kenya with
    relation to land use practices was investigated. The
    study areas were chosen because of their significant
    land use intensification and for being biodiversity hot
    spots. Soil washing and dilution plate techniques were
    used to recover Trichoderma spp from the soil samples
    collected from different land use types. The fungal
    isolates were identified and assigned to nine species
    from Embu soils and eleven species from the Taita
