Monitoring vegetation phenological stages using remote sensing data for pasture management in selected asals of Kenya

The objective of this study was to monitor phenological stages of grassland in selected ASALs of Kenya, so as to provide information for sustainable pasture management. NDVI data obtained by the VEGETATION instrument onboard SPOT satellite was extracted over three selected ASAL districts of Kenya namely, Kajiado, Garissa and Baringo. Extraction points were based on a land cover map that showed the location of grassland in the three districts. Piecewise logistic functions were applied on the extracted NDVI data in order to identify phenological stages.

Participation of women in income-generating activities: a case study of Dandora, Nairobi, Kenya

The study aims at finding out factors which determine women's participation in income-generating activities, the amount of income women gain in a month and problems which face women participating in income-generating activities.

Borders, Frontiers and Security: a Case Study of Marakwet and Pokot Districts, Kenya

The objective of this thesis is to investigate and identify security issues arising from Marakwet and Pokot community interactions across internal boundaries, international borders and into their community frontiers. It analyses the Marakwet and Pokot community interactions in their domicile localities of West Pokot and Marakwet districts in Kenya. The study examines the interactions particularly at the shared borders between the two districts of Marakwet and Pokot, and it is hypothesized that community movements and interactions into their frontiers contribute to insecurity.

Spatial analysis of risk factors and their effects on peste des petits ruminants control strategies in kajiado and marsabit pastoral systems of Kenya

The contribution of sheep and goats to pastoralist livelihoods and economies is limited by the frequent occurrence of small ruminant diseases such as Peste des Petits Ruminants (PPR). PPR, also known as ‘goat plague’, is a highly contagious viral disease of sheep and goats characterised by sudden onset of depression, bilateral eye and nasal discharges, mouth sores , pneumonia, foul-smelling diarrhoea and death. In susceptible small ruminant herds, PPR virus infections result in high morbidity rates of 90 percent (%) and mortality rates of 70%.

The antiplasmodial, toxicity and pharmacokinetic properties of synthetic derivatives of the natural product Curcumin

Malaria is the most devastating protozoal infection in humans. There is widespread resistance to existing antimalarial agents hence the need for new antimalarial drugs. Curcumin, a natural product isolated from Curcuma /ongaldomestica, was used as a scaffold for the synthesis of new compounds with antiplasmodial activity. Curcumin was selected because of its low toxicity and is commercially available at a low cost.. Derivatives of curcumin were designed to act against selected molecular targets in Plasmodium falciparum.

Determination of heavy metals in lates niloticus and caridina nilotica from winam gulf of Lake victoria using x-ray fluorescence

Heavy metals have been recognised to be a major source of pollution in the aquatic ecosystems. Lates niloticus and its caridina nilotica feed, was selected as bioindicators because of their abundance in the gulf of Winam and their predator - prey relationship. The heavy metals determination was done by the x-ray fluorescence (XRF) analytical technique. For quality control Atomic Absorption Spectrophotometry (AAS) was also used for some samples.

Social structure and environment: two case studies from Eastern Kenya

The study assumes that social structures, seen in terms of role allocation, differentiation and relations, is to a large extent influenced by various environmental factors, with a particular emphasis on the physical. The interest in the topic of this study arises out of the need to understand people's ways of life and needs in different environmental settings the knowledge of which would facilitate relevant planning for such people

The influence of socio-economic and demographic factors on fertility levels in Nairobi

Nairobi which is the study area, is the largest urban centre and capital of Kenya. It acquired its urban status in 1950. It is located almost at the centre of the country. From North to south, it stretches from 2010'S to 2050'S and from East to West, it stretches from 370 10'E to 360 40'E, thus covering an area of 684 square kilometres. According to the 1979 Kenya population census statistics, Nairobi had a total population of 827,775 people. This was 5.4 per cent of the total annual population of Kenya which was 15,327,061 people.

Mathematical modelling and design of a three-dimensional geodetic network for localised earth deformation

Mathematical model is , within the framework of integrated geodetic networks for localised three dimensional geodetic monitoring networks are presented. The network design aspects has also been considered. The development of these mathematical models was based on the kinematic estimation model of geodetic network adjustment using the inte rated geodetic approach. The network design aspect considered was the weight problem for each of the various observables used.

Towards a national spatial data infrastructure (NSDI): inventory and evaluation of existing geospatial datasets and systems in Kenya

In Kenya there are presently about 50 institutions with GIS installations and it has generally been noted that there are duplications of effort in the production of geospatial data. Again, co-operation among these institutions is minimal. In order to realize an effective, infrastructure-enabled data sharing arrangement, NSDI in Kenya, an inventory of the available geospatial datasets and systems is needed. From such an inventory, it is possible to determine the capabilities and needs of individual institutions and also to identify specific areas for increased co-operation.
