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 -

"This manual is intended for national trainers on environmental crime in Eastern and Southern Africa. It seeks to enable such trainers to equip police officers and other actors involved in fighting environmental crimes with knowledge and understanding of the nature of environmental crimes, environmental inspection and investigation, and prosecution of environmental crimes. Its methods are based specifically on a participant-centred learning approach to facilitate optimum participation of learners."

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.

Pythium is a water mould fungus which survive as a parasite, saprophyte or both. Pythium
spp. play important ecological services like recycling of both Carbon and mineral
nutrients for continued plant growth. Members of this genus are ubiquitous and found in
soil, water, plants and animal substrate. Spatial distribution and species diversity of
Pythium were studied with aim of determining the effects of intensive agricultural
practices on distribution and diversity. Agricultural intensification interferes with the -

Strategy implementation is the translation of chosen strategy into organizational action so as to achieve strategic goals and objectives. Strategy implementation is also defined as the manner in which an organization should develop, utilize, and amalgamate organizational structure, control systems, and culture to follow strategies that lead to competitive advantage and a better performance. The main objectives of this study were to investigate the challenges of strategy implementation in the ministry of Northern Kenya and other arid areas.

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.

Tropical rainforests are characterized by habitat stability and complexity. Hence, the forests
support a rich biological diversity, including 40% of all bird species. However, these rain
forests have been shrinking due to increasing rate of deforestation, fragmentation, and other
forms of resource exploitation. Degradation and loss of rainforests has threatened their rich
biological diversity and the life-support systems. However, the rate at which birds are
displaced by forest clearing and the potential for birds' conservation on farmlands are not -

This chapter presents and discusses the causes of land degradation, and ways of sustainable land development and agricultural productivity. The evidence presented here suggests several avenues for achieving a world without land degradation. First, efforts to promote sustainable land management need to improve locally and nationally. Second, instead of focusing solely on fertilizer subsidies, countries should use broader and more cost-effective incentives to encourage farmers to adopt integrated soil fertility management.
