Globalization and Biodiversity Conservation Problems: Polycentric REDD+ Solutions
(MDPI, 2019-02-19)Noise barriers are the most widespread solution to mitigate noise produced by the continuous growth of vehicular traffic, thus reducing the large number of people exposed to it and avoiding unpleasant effects on health. ... -
Impacts of Bush Encroachment on Wildlife Species Diversity, Composition, and Habitat Preference in Ol Pejeta Conservancy, Laikipia, Kenya
(Hindawi International Journal of Ecology, 2017)Savannah ecosystems are currently facing a biome shift that changes grasslands to woody dominated landscapes, attributable to habitat degradation. In Ol Pejeta Conservancy (OPC), Eucleadivinorum, an unpalatable and invasive ... -

Influence of Adherence to Quality Management System Standards on Access to Water and Sanitation Services in Kenya
(IOSR Journal Of Humanities And Social Science, 2018-02)In Kenya, over 3,100 children die annually for using unsafe water and poor sanitation. In the 2015/2016 financial year, access to water in Kenya stood at 54% for urban and 51% for rural areas. This low access to water and ... -
Influence of cattle on browsing and grazing wildlife varies with rainfall and presence of megaherbivores
(The Ecological Society of America, 2017)In many savanna ecosystems worldwide, livestock share the landscape and its resources with wildlife. The nature of interactions between livestock and wildlife is a subject of considerable interest and speculation, yet ... -
Influences of Human Activities on Tree Density and Diameter Distribution in Museve and Mutuluni Dryland Forest Fragments; Kitui County, Kenya
(Journal of Tropical Forestry and Environment, 2019-05-14)Forest fragments in Arid and Semi-Arid Lands are key water catchment areas and provide important ecosystem services. However, uncontrolled human activities are fast altering their stem density basal area and diameter ... -
Macroinvertebrate metrics and lipid profiles as potential indicators of land use influence in a high altitude tropical highland stream (Sagana River Basin, Kenya)
(Elsevier, 2024)Land use practices near river ecotones result in numerous inputs of terrestrial materials into the river ecosystem. While macroinvertebrates population metrics is widely used in monitoring water quality changes, including ... -
Naïve plant communities and individuals may initially suffer in the face of reintroduced megafauna: An experimental exploration of rewilding from an African savanna rangeland
(PLOS ONE, 2021-04-06)Excluding large native mammals is an inverse test of rewilding. A 25-year exclosure experiment in an African savanna rangeland offers insight into the potentials and pitfalls of the rewilding endeavor as they relate to the ... -

(Environ Monit Assess, 2016)Polychlorinatedbiphenyls(PCBs)areclassified as persistent organic pollutants (POPs) regulated by the Stockholm Convention (2001). Although their production and use was stopped almost three decades ago, PCBs are environmental ... -
POPULATION ECOLOGY, DIET AND MOVEMENT OF STRAW-COLOURED FRUIT BATS (Eidolon helvum), WESTERN KENYA
(research gate, 2012-07)The population status, movement, roost-site selection and diet of straw-coloured fruit bats (Eidolon helvum) were studied over a seven-month period in western Kenya. Overall, the bat population fluctuated markedly from as ... -
A Public-Private Partnership Scheme To Avert Desertification in the Drylands of Kenya: Lessons for Social Scientists
(University of Dar es Salaam, 2016)The drylands of Kenya make up about 80% of the total land area and are defined by aridity, thermal stress, soil moisture deficiency and general human want. The poverty bedevilling the drylands leave their inhabitants without ... -
Relationships Between Cattle and Biodiversity in Multiuse Landscape Revealed by Kenya Long-Term Exclosure Experiment
(Elsevier, 2018-05)On rangelands worldwide, cattle interact with many forms of biodiversity, most obviously with vegetation and other large herbivores. Since 1995, we have been manipulating the presence of cattle, mesoherbivores, and ... -
The Role of Selected Environmental Factors on the Regeneration of (Ocotea usambarensis ) in Mount Kenya Forest, Kenya
(International Journal of Agriculture, Environment and Bioresearch, 2018)Despites the propagation efforts, density of Ocotea usambarensis has continued to diminish in the southern slopes of Mount Kenya. The species which is native in the montane forest is seldom on farm and found as remnant ... -
