Natural entomopathogenic nematodes (EPNs) are considered as potential biological control agents against soil-borne insect pests. This study was conducted to determine the impact of land use on the distribution, occurrence and diversity of entomopathogenic nematode community. Isolation of EPNs was done using the baiting technique and application of morphological identification methods revealed presence of the genus Steinernema. Land use intensification negatively affected the occurrence and recovery frequency in soils of Embu and Taita districts.

Kimana Group Ranch (KGR) is a critical wildlife dispersal area for Amboseli National Park in Kenya. But
irrigated agriculture in the group ranch is leading to increased conflicts and competition for land and other critical
resources. This study used semi – structured interviews with group ranch members on their interactions with wildlife,
resource use and access, land use changes and livelihoods. Most group ranch members practiced agriculture as opposed to -

During the last forty years, the economic and demographic structure of Kenya has become increasingly urban. In
the 1980s the urban population in the country grew at over
6.5 percent a year, more than double the rate for the
rural population. This expansion has occurred even under the most adverse conditions of repressed urban
investment, as was the case during the 1990s.

Vulture population declines have been noted in West and Southern Africa, but have not been assessed in East Africa. Roadside transects conducted in 1976 and 1988 were compared with surveys done from 2003–2005 in and around Masai Mara National Reserve, Kenya. Staggering declines in abundance were found for seven of eight scavenging raptors surveyed. No Egyptian vultures were seen during recent transects.

Rangelands in semi-arid Kenya have recently witnessed extensive land use changes. These changes can mainly be attributed to increased livestock populations and the response of the increased human population to both local and exogenous opportunities and constraints. This study was carried out in Kibwezi district of Kenya mainly inhabited by agro-pastoralists. The main objective of this study was to establish how different land use types influence soil properties in tropical semi-arid rangelands.

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.

Kenya’s land surface is primarily arid and semi-arid lands (ASALs) which account for 84% of the total land area. The Desert Margins Programme (DMP) in Kenya has made some contribution to understanding which technology options have potential in reducing land degradation in marginal areas and conserving biodiversity through demonstrations, testing of the most promising natural resource management options, developing sustainable alternative livelihoods and policy guidelines, and replicating successful models.
