Assessment of the Extent of Land Degradation in the River Loboi Watershed of Baringo County, Kenya
(2015)Increased human population pressure and climate change constitute the global underlying root causes of accelerated and devastating land degradation processes in the Arid and Semi-Arid Lands (ASALs). River Loboi watershed, ... -
Modelling Climate-based changes of sugarcane growing areas in Western Kenya
(2016)Sugar cane (Saccharum spp. hybrids) is an important cash crop for Kenya’s sugar industry contributing significantly to the country’s economy through farming and employment. Its production in Kenya is both irrigation and ... -
Effects of Climate Variability on Foraging Behaviour of Bees: A Case Study of Marigat and Ratat locations in Baringo County, Kenya
(2018)Beekeeping is among the livelihood diversification strategies likely affected by climate variability. The variation in temperature and rainfall influence forage phenology impacting on honey production in arid and semi-arid ... -
Socio-economic and Environmental Concerns of Water Resources Management in the Tana Basin, Kenya
(School of Environmental Studies and Human Science, Kenyatta University, 2007)Water is an essential resource for the development of any country and its availability is the most limiting factor for socio-economic progress and advancement. Due to various factors, there is a growing need for more water ... -
The Potential Impacts of Climate Change on Human Health and the Need for Health Education in Kenya
(Joypet Sevices & Printers Ltd, 2007)Human health is dependent on a good and clean environment and many of the factors that lead to a deteriorated environment also lead to poor health. Pollution of the atmosphere, lack of sufficient and! or polluted water ... -
Regionalization of the Upper Tana Basin of Kenya Using Stream Flow Records
(Department of Civil Engineering, JKUAT, 2007)In this study, the upper Tana basin of Kenya was delineated into homogenous hydrological zones based on monthly stream flow records from several river gauge stations in the basin using the empirical orthogonal function ... -
Forest cover change and ecosystem services of Katimok forest reserve, Baringo County, Kenya
(Springer, 2019)Forests provide vital ecosystem services to communities living around them, contributing immensely to their livelihoods. Yet, these forests undergo land use changes that threaten the abundance and availability of ecosystem ... -
The Cost-Benefit Analysis of Fisheries Management Systems in Kenya: The Case of Lake Victoria
(2014)Fisheries management costs are widely becoming issues used to choose among policy objectives. We provide simple calculations by drawing on the experience from Lake Victoria fisheries. The study applied cost- benefit analysis ... -
Spatial Modeling of Sorghum (Sorghum bicolor) growing areas in Kenyan Arid and Semi-Arid Lands Charles
(Elixir, 2014)Sorghum (Sorghum bicolor) is an important African cereal crop and is listed among Africa’s lost crops but is now gaining popularity as other cereals are declining in production due to climatic change. To promote food ... -
Interactive comment on“Hillslope experimentdemonstrates role of convergence during two-stepsaturation”byA. I. Gevaert et al.
(Hydrology and Earth System Sciences, 2014)Based on experimental results, obtained from a large scale physical model, Gevaertet al. (2014) attempt to present an alternative physical process of the formation of agroundwater ridge; its dependence on the shape of a ... -
Mapping Vulnerability to Climate Change in Malawi: Spatial and Social Differentiation in the Shire River Basin
(Scientific Research Publishing Inc., 2015)This article analyses vulnerability to climate related shocks across five districts in the shire river basin of Malawi. The analysis employs an indicator approach that integrates biophysical and socio-economic indices. ... -
A global review of the downstream effects of small impoundments on stream habitat conditions and macroinvertebrates
(NRC Research Press, 2015)The downstream ecological effects of large impoundments have previously been reviewed; however, little is known about the downstream ecological effects of small man-made impoundments. In this review, we examine 94 papers ... -
A model of landslide triggering bytransient pressure waves
(Copernicus GmbH, 2014)Previous studies indicate that most rainfall-triggered shallow landslides are initiated by a spike in rainfall intensity, which does not usually occur at the beginning of a critical storm, within which the slide is triggered, ... -
Energy considerations in groundwater-ridging mechanism ofstreamflow generation
(Hydrological Processes, 2015)Groundwater ridging is the rapid rise of a shallow water table during a rainfall event, in an environment where, in the pre-event period, the capillary fringe extends to the ground surface. Groundwater ridging is widely ... -
Transmission of pressure head through the zone of tension saturation in the Lisseeffect phenomenon
(Taylor & Francis, 2016)The problem of transmission of pressure head through the zone of tension saturation in the Lisse effect(LE), i.e., the rapid response of groundwater level to pressurized pore air in the unsaturated zone, is investigated ... -
Transient pressure waves in the vadose zone and the rapid water table response
(The Soil Science Society of America, Inc., 2013)The behaviour of a water table is important in understanding groundwater dynamics. In this 11 paper, results are presented of a disproportionate response of a water table in two distinct 12 transient pressure wave ... -
Do Smallholder Farmers Perceive Rainfall Variability the Same and Correctly? Gendered and Spatial Analysis of Perception Versus Actual Trends of Rainfall in Three Livelihood Zones in Kenya
(Journal of Environment and Earth Science, 2018)In this paper we compared perceived rainfall variability with actual rainfall variability using a more nuanced and mixed approach in order to understand the influence of gender dynamics and spatial location on perceptions. ... -
Improving the Participationof Agro-Pastoralists in Climate ChangeAdaptation and Disaster Risk ReductionPolicy Formulation: A Case Studyfrom Keiyo District, Kenya
(2011)rowing scientific evidence suggests that climate change will acceler-ate weather extremes and increase human vulnerability to disasters. Exposure ofagro-pastoralists to erratic rainfall and cyclical droughts leads ... -
Impact of Population Growth and Climate Change on the Freshwater Resources of Lamu Island, Kenya
(2015)Demand for freshwater is rising with factors, such as population growth, land use change and climate variations, rendering water availability in the future uncertain. Groundwater resources are being increasingly exploited ... -
Freshwater resource characterization and vulnerability to climatechange of the Shela aquifer in Lamu, Kenya
(Journal of Environment and Earth Science, 2015)Salinization of coastal groundwater systemscauses a severe deterioration both in amount and quality offresh groundwater resources. To support the sustainableuse and management of fresh groundwater, ...
