    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.

    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 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

    Survey of Kenya is the country's institution charged with the
    responsibility of collecting, checking, storing and disseminating Land
    parcel related records.
    Of late efforts have been made to digitize these records and form a
    database. However the majority of the records are in paper form.
    Dissemination of this data, done through a search, is still manual. The
    public fill a search form and pay a small fee, and the records are
    reproduced to them in form of a filled and dully signed form or map or

    Participatory rural appraisal techniques and a survey of 100 households were used to evaluate livestock production, and pastoral development of the Maasai in Mara. It was observed that patterns of land-use have principally changed from nomadic pastoralism to sedentary pastoralism, agropastoralism, and, in some cases, pure cultivation. These trends have adversely affected livestock production and the productive capacity of the Mara ecosystem.

    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

    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.

    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
