Land and Population Problems in Kajiado and Narok, Kenya
(Cambridge University Press, 1984-03)The physical appearance of Africa's marginal semi-arid lands shows evidence of eroding hillsides, denuded plains, large erosion shelves, and deep sheer-sided gulleys. These features manifest an imbalance between humans and ... -
Evaluation of agrometeorological indices as maize yield predictors in a high rainfall Kenyan environment
(East African Agricultural and Forestry Journal, 1990)Maize is the most important food crop in Kenya and occupies more than 25% of the total land area in many high rainfall areas of the country. Investigations were carried out to test which agrometeorological crop yield ... -
A Review of Methods for Estimating Evapotranspiration
(Kluwer Academic Publishers, 1991)The problems which characterize the study of evapotranspiration are briefly discussed. Different models which have been used for estimating evapotranspiration are reviewed. They include the eddy correlation model, mass ... -
“Heat island” in a Humid Tropical City and its Relationship with Potential Evaporation
(Springer-Verlag, 1991) -
Day-time Effects of Urbanization on Relative Humidity and Vapour Pressure in a Tropical City
(Springer-Verlag, 1991) -
Responding to population pressure in the rural Kenya
(Kluwer Academic Publishers, 1993-08)This paper reviews different historical and contemporary factors responsible for population pressure in the rural Kenya. It is argued that the process is not new, having its roots in the colonial administration. Cultural ... -
Field Assessment of Flood Event Suspended Sediment Transport from Ephemeral Streams in the Tropical Semi-Arid Catchments.
(PubMed, 1995-03)An assessment of suspended sediment transport was carried out in a number of semiarid catchments during flood events in order to quantify the degradation rates. In order to quantify these, a systematic sampling procedure ... -
Multivariate analysis of plant communities in the Narok district, Kenya: The influence of environmental factors and human disturbance
(Kluwer Academic Publishers, 1996)Species type in 42 samples was examined using ordination analysis to establish whether the vegetation pattern displays gradation due to environmental factors, and whether the pattern was being altered by human disturbance. ... -
Modelling the impact of land abandonment on runoff and soil erosion in a semi-arid catchment.
(University of London, 1997)The overall aim of this research is to evaluate the dynamic interactions between soil moisture, vegetation and erosion of abandoned land in a semi-arid setting within the context of changing climate, with a view to ... -
Conflicts over resources: Saiwa Swamp National Park (Kenya) and its environs
(Kluwer Academic Publishers, 1997)This paper examines conflicts in Saiwa Swamp National Park and adjacent households. The conflicts centre on poaching of park resources and destruction of park ecology on the one hard and, the spread of diseases, crop damage ... -
Phenological and physiological evaluation of the potential of Tohono O'odham Z16 maize as a new crop for the semi-arid areas of SE-Kenya
(Journal of Agriculture in the Tropics and Subtropics, 1997)This study intends to compare the phenology, crop water requirements and the diurnal behaviour of leaf water potential of the new maize variety Tohono O'odham Z16 and of the locally grown varieties, i.e. Makueni DLC and ... -
Potential of Episodic Flows in Some Four Representative Non-perennial River Flow Catchments in Semi arid Laikipia District, Kenya
(Kluwer Academic Publishers, 1997)The purpose of this study was to establish the water resources of thenon-perennial streams in providing supplementary water needs inLaikipia district. This district has undergone remarkable land usechanges resulting in ... -
Variations of the effective temperature index (ET) in Kenya
(GeoJournal, 1998)Using the Effective Temperature Index (ET) as a measure of climatic comfort conditions in Kenya, this study analyses its spatial, seasonal and diurnal variations. This index is computed using data collected from 57 weather ... -
Phenology and Diurnal Course of Leaf Water Potential of Three Bean Varieties under a Semi-Arid Environment in South-East Kenya
(Faculty of Science Kenyatta University, 1998)The objectives of this study were to observe the phenology and to investigate the diurnal behaviour of leaf water potential (LWP) in three bean varieties under irrigated and unirrigated treatments with a view to making ... -
An investigation of the influence of human disturbance on selected soil nutrients in Narok District, Kenya
(Kluwer Academic Publishers, 1999)Selected soil nutrients were analysed purposely to establish whether they display a spatial pattern due to environmental factors and whether the pattern has been affected by human activities. Data analysis involved descriptive ... -
Biological Nitrogen Fixation in Selected Legumes of the Semi-Arid Makueni District of Southeast Kenya
(Journal of Agriculture in the Tropics and Subtropics, 1999-10)The major objective of this study was to investigate biological nitrogen fixation in two main legumes (green gram and common bean) grown in semi-arid southeast Kenya. Nodulation experiments on the two legumes were carried ... -
Crop water relationships and thermal adaptation of kathika beans (Phaseolus vulgaris L.) and green grams (Vigna radiata L. Wilczek) with special reference to temporal patterns of potential growth in the drylands of SE Kenya
(Journal of Arid Environments, 2001)High soil temperatures influence seedling emergence as well as the performance of plant organs and yields. Temperatures of above 40°C were recorded in the topsoil of the Ferralsols of the semi-arid areas of SE Kenya during ... -
Improvement of drought adapted tepary bean (Phaseolus acutifolius a. Gray var. latifolius) yield through biological nitrogen fixation in semi-arid SE-Kenya
(European Journal of Agronomy, 2002-01)Tepary bean (TB), a drought adapted bean variety has recently assumed prominence among resource poor farmers in semi-arid SE-Kenya. However, its productivity is still low because of inadequate inputs. Greenhouse experiments ... -
The impact of ecotourism on livelihood and natural resource management in Eselenkei, Amboseli Ecosystem, Kenya
(Wiley, 2002-06)This paper presents the impact of ecotourism† on livelihood and natural resource management in the periphery of Amboseli Biosphere Reserve in Kenya. Ecotourism initiatives that have been introduced by Porini Ecotourism, a ... -
A note on the response by smallholder farmers to soil nutrient depletion in the East African highlands
(WFL Publisher Science and Technology, 2003)Agriculture provides a major share of national income and export earnings in many developing countries while ensuring food security, income and employment to a large proportion of the population. Many people in developing ...
