Evaluation of Sesame Cultivars for Resistance to Cercospora Leaf Spot
(Taylor & Francis, 1995)Sixteen sesame accessions (Table I) were obtained from the germplasm collection of the Sesame Improvement Project of the University of Nairobi. 1nocula of C. sesamicola were prepared using the technique described by Robert ... -
Cultural studies on two cercospora species of sesame and their interactions with some sesamum germplasm in Kenya
(University of Nairobi, 1997)Conditions influencing in vitro growth and sporulation of Cercospora sesami and C. sesamicola were investigated to determine appropriate techniques for producing adequate quantities of inocula for use in the creation of ... -
An investigation into some water quality problems of Lake Kanyaboli in Kenya
(University of Nairobi, 1997)This study attempted an investigation into some water quality problems of jake Kanyaboli. The geographical location of lake Kanyaboli within the Yala swamp and its size of 10.5km1 make it ideal for this investigation. ... -

Sewage reuse for irrigation in Athi River town: its implications on public health
(Moi University, 1998)Lead, cadmium, selenium and arsenic were the selected indicators of toxic heavy metals which were determined using atomic absorption spectroscopy (AAS) in sewage being reused for irrigation in Athi River town of Kenya. ... -

(Moi University, 1998)Lead, cadmium, selenium and arsenic were the selected indicators of toxic heavy metals which were determined using atomic absorption spectroscopy (AAS) in sewage being reused for irrigation in Athi River town of Kenya. ... -
Sewage re-use for irrigation in Athi River Town Kenya: its implications on public health
(Elsevier, 1999)Occupational environmental health associated with both industrial and domestic sewage reuse for food production in Athi River town Kenya has been studied. The levels of toxic heavy metals such as lead, cadmium, selenium ... -
Interannual variability of NDVI and species richness in Kenya
(International Society for Photogrammetry and Remote Sensing (ISPRS), 2000)A central task in community ecology is to determine biophysical controls of species richness patterns. Most multivariate models relating environmental characteristics to species richness were developed with sparse point ... -
Comparing different epidemiological models in field evaluations of selected genotypes from Solanum tuberosum CIP population A for resistance to Phytophthora infestans (Mont.) De Bary in Kenya
(Kluwer Academic Publisher, 2000)Late blight caused by Phytophthora infestans was monitored in field plots of potato genotypes selected from population A of the International Potato Center (CIP) germplasm collection. Disease severity was measured as percent ... -
Interannual variability of NDVI and bird species diversity in Kenya
(Elsevier, 2000-01-01)Species richness, or simply the number of species in a given area, is commonly used as an important indicator of biological diversity. Spatial variability in species richness has been postulated to depend upon environmental ... -
Spatial patterns of species diversity in Kenya
(2001)It is evident to any biologist that small-bodied species within a given higher taxon (order, class, phylum, etc) tend to be represented by more individuals. Hence smallbodied species are generally more abundant than ... -
Environmental factors influencing bird species diversity in Kenya
(Blackwell Publishing Ltd, 2001-09)Sustainable resource management requires understanding the factors that increase or decrease species richness. Regional species richness patterns may be predicted by analysing patterns of variation in the environment. A ... -
Body size and abundance relationship: an index of diversity for herbivores
(Kluwer Academic Publishers, 2001-11-01)It is evident to any biologist that small-bodied species within a given higher taxon (order, class, phylum, etc.) tend to be represented by more individuals. Hence small-bodied species are generally more abundant than ... -
Mapping habitat and biological diversity in the Maasai Mara ecosystem
(Taylor & Francis Group, 2003-01-01)There is need to identify ecosystems that support richer assemblages of biological species in order to preserve habitats and protect the greatest number of species. Remotely sensed data hold tremendous potential for mapping ... -
Biodiversity assessment by remote sensing
(2003-11-10)Measuring the complexity of species in (semi) natural environments is time consuming and expensive. In this paper we summarise remote sensing techniques developed for mapping and monitoring biodiversity of herbivores ... -
Scenario study for Flood Hazard Assessment in the lower Bicol Floodplain Philippine using A 2D Flood model
(ITC, 2004-03)In the frameworks of the ITC Projects (SLARIM) Strengthening Local Authorities in Risk Management, a case study was carried out on hazard assessment on Lower Bicol floodplain. The floodplain is located in four provinces ... -
Utilization of Wetland Ecosystems for Sustainable Livelihoods: The Case of Osodo in the Lake Victoria Basin.
(Maseno University, 2006) -
Hydrogeological Study of the Area North of Menengai Crater Using Electrical Resistivity Survey
(Nairobi university, 2006)An integrated study involving geophysical, geological and hydrogeological investigation was undertaken to determine groundwater potential in the areas north of Menengai Crater. Rocks exposed in the study area represent a ... -
The Plight of Fisher folk in the Fishing Industry in the Lake Region.

THE DIMINISHING WEALTH: THE CASE OF NYAMASARIA WETLANDS IN KISUMU TOWN
(Egerton university press, 2007-04)Although household food security may not capture all dimensions of food such as availability, access and utilisation; inability of households to put enough and quality food on the table is a manifestation of bad food ...
