Spatio-temporal dynamics of land use practices on rivers in tropical regions: A case study of Ruiru and Ndarugu Basins, Kiambu County, Kenya
(2017-03)Land use dynamics are known to cause considerable modifications to the environment with broad and sometimes severe impacts on water quality and aquatic natural resources. In this study, the impacts of land use practices ... -
Biomass Energy Resource of the Highland Bamboo (Yushania alpina) and Its Potential for Sustainable Exploitation in Southern Aberdares Forest
(Scientific Research Publishing, 2017-08)Yushania alpina is the only bamboo species native to Kenya and covers about 150,000 ha growing in pure or mixed stands in the montane forests. The Aberdare forest is one of the natural habitats for Y. alpine occupying an ... -
Assessing Climate Variability Adaptation and Coping Strategies Among Rural Households in Kenya.
(Journal of Water Sciences & Environment Technologies, 2018)The aim of this study is to assess the adopted water scarcity adaptation and coping strategies of rural households to climate variability. It also identifies suitable strategies that minimize the impact of climate variability ... -
Diversity and Altitudinal Distribution of Understorey Corticolous Lichens in a Tropical Montane Forest in Kenya (East Africa)
(research gate, 2018)Lichens constitute an important component of tropical forest biodiversity. This study inventoried corticolous lichens and examined their variation in various forest types with varying climatic conditions in Mt. Kenya, East ... -
Climate Change Perception Among the Pastoralist Women in Narok County
(Academic Research International, 2018-03)With regards to the effects of climate change, Kenya has identified its ASALs as the most vulnerable areas to climate change with huge impacts on livestock rearing, small-holder agriculture and tourism, which are the ... -

Ecological, Recreational and Educational Potential of a Small Artificial Wetland in an Urban Environment
(African Journal of Aquatic Science, 2019-11)Pertinent questions remain on whether small, artificial wetlands, such as abandoned quarries play any ecological or socio-economic role in the environment. To increase information on roles played by small-sized artificial ... -
Carbon Sequestration by the Above Ground Biomass Pool in the South West Mau Forest of Kenya, 1985 - 2015
(Journal of Environment and Earth Science, 2020)Forests are important for regulation of the global carbon balance. Increase in forest biomass enhances atmospheric carbon sequestration while decrease in forest biomass contributes to carbon dioxide emissions. World over, ... -
Trend and Variability in Interannual Air Temperature Over South West Mau Forest, 1985 - 2015
(Journal of Natural Sciences Research, 2020)Globally high altitude forest regions are considered to be more prone to rapid warming. These regions have also shown great seasonal and inter annual temperatures variability. In Kenya mean annual temperatures increased ... -
Radiometric survey of the Tyaa river sand mine in Kitui, Kenya
(2020-07-02)Gamma spectroscopic analyses of sand and rock samples from Tyaa River report an average activity concentration of 33 ± 1, 55 ± 2.8 and 812 ± 40.46 Bqkg-1 for 226Ra, 232Th and 40K, respectively in the sand. A similar analysis ... -
5. Absentee owners and overlapping home ranges in a territorial species
(2021-01-07)Abstract Understanding animals’ use of space can shed valuable light on multiple other aspects of behavioral ecology, including social organization, dispersal, and foraging efficiency. Home ranges, territories, core areas, ... -
Using the Biological Condition Gradient Model as a Bioassessment Frameworks to Support Rehabilitation and Restoration of the Upper Tana River Watershed in Kenya
(Frontiers in Environmental Science, 2021-07)The biological condition gradient (BCG), a scientific framework that describes the change in ecosystem characteristics in response to human-induced levels of stressors, was modified and used to characterize watershed ... -
Evidence of nutrient translocation in response to smoke exposure by the East African ant acacia, Vachellia drepanolobium
(Wiley & Sons Ltd, 2021-09)1. Fire is a major selective force on arid grassland communities, favoring traits such as the smoke-induced seed germination response seen in a wide variety of plant species. However, little is known about the relevance ... -
Fine‐scale variation in soil and topography influences herbaceous vegetation and the distribution of large mammalian herbivores
(Wiley, 2023-04)Current understanding of the distribution of vegetation and large mammalian herbivores (LMH) is based on a combination of biogeographic studies and highly controlled field experiments, but a more complete understanding ... -
Analysis of Short-Term Drought Episodes Using Sentinel-3 SLSTR Data under a Semi-Arid Climate in Lower Eastern Kenya.
(2023-06)This study uses Sentinel-3 SLSTR data to analyze short-term drought events between 2019 and 2021. It investigates the crucial role of vegetation cover, land surface temperature, and water vapor amount associated with ... -
Hourly reference evapotranspiration analysis using synoptic meteorological measurements and ERA5 reanalysis data from Kenyan Counties
(2023-09)Kenya has had five failed rain seasons for the last three years. In this context, there was a mass recurrent crop failure, death of livestock and wildlife, persistent water scarcity, and droughts of varying intensities. ...
