Allometric Equations for Estimating Silk Oak (Grevillea robusta) Biomass in Agricultural Landscapes of Maragua Subcounty, Kenya
(Hindawi International Journal of Forestry Research, 2018)Grevillea robusta is widely interplanted with crops in Maragua subcounty, a practice that enhances biomass quantities in farmlands. However, quick tools for estimating biomass of such trees are lacking resulting in ... -
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 ... -
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 ... -
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 ... -
Framing natural assets for advancing sustainability research: translating different perspectives into actions
(Springer, 2018)Sustainability is a key challenge for humanity in the context of complex and unprecedented global changes. Future Earth, an international research initiative aiming to advance global sustainability science, has recently ... -
Spatial scales influence long-term response of herbivores to prescribed burning in a savanna ecosystem
(CSIRO PUBLISHING, 2017-01)Both wild and prescribed fire in savanna ecosystems influence habitat use by herbivores by creating or maintaining spatial and temporal heterogeneity in forage quality and vegetation cover. Yet little is known about how ... -
Fire disturbance disrupts an acacia ant–plant mutualism in favor of a subordinate ant species
(Wiley and sons, 2017-03)Although disturbance theory has been recognized as a useful framework in examining the stability of ant–plant mutualisms, very few studies have examined the effects of fire disturbance on these mutualisms. In myrmecophyt ... -
Estimation of Above Ground Biomass in Forests Using Alos Palsar Data in Kericho and Aberdare Ranges
(Scientific Research Publishing, 2017)Above Ground Biomass is one of the six pools identified in the inventory of forest resources and estimation of greenhouse gas emissions and sinks from the forestry sector. The pool varies by management practices in different ... -
Impact of human activities on land degradation IN Lugari subcounty, Kakamega county, Kenya
(E3 Journals, 2016-10)This study investigated the impact of human activities on land degradation in Lugari Sub-County, Kakamega County in Kenya. The study sought to analyze the extent of land degradation; identify the causative factors for land ... -
Effects of Sawdust, Forest Soil and Cow Dung Mixtures on Growth Characteristics of Blue Gum (Eucalyptus saligna) Seedlings in South Kinangop Forest, Nyandarua, Kenya
(Scientific Research Publishing, 2017-09)Forestation programs, in Kenya have been hindered by, among others, high cost of tree seedling production and longtime seedlings stay in the nursery. This has been attributed to poor quality of forest soil and unavailability ... -
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 ... -
