MRiver Njoro has been experiencing a gradual decline in the quality and quantity of water, resulting in various waterborne diseases among people living in the watershed. The current study covers the period 1998 - 2002. The main objective of the study was to document the prevalence of waterborne diseases in River Njoro watershed and their implications on human health. Medical data from a purposive sample of three health institutions within the watershed for the aforementioned period was collected. ln addition, Participatory Rural Appraisal (PRA) reports for the area were reviewed to document community's perceptions. Questionnaires were also administered to clinical officers in the sampled institutions. A data registration form was developed to collect case register data on the waterborne diseases. The study focused on four diseases, namely; diarrhoea, amoebiasis, typhoid and bacillary dysentery. The data collected was analysed using Epidemiology Information System 2002 (Epi Info 2002) and tables and graphs generated showing the annual and seasonal trends in the prevalence of the diseases. The study found out that, diarrhea cases increased in Nessuit during the dry season as opposed to the cases in Njoro and Kapkures, which were lower during dry months. The situation is however, reversed upon the onset of rainy seasons. Diarrhoea and Bacillary dysentery were common in children below 2 years while typhoid and amoebiasis were common among adults above 20 years. This could be attributed to infective dose, responsible for various diseases. The PRA reports indicated that water-related diseases and water shortages were among the most important issues affecting residents in the watershed. Community members pointed out the revival of stalled water projects and harnessing of rainwater as some of the ways that could reduce the incidence of the diseases. The cost estimates for diarrhoea and typhoid were Kshs 568 and Kshs 2,029 respectively. These costs did not include other costs such as pain and suffering by family members. The study demonstrated there was a correlation between the incidence of waterborne disease and the quality and quantity of water in River Njoro.Item Trends , Local Perceptions and Cost of Waterborn Diseases in River Njoro Watershed, Nakuru District(Egerton University, 2006-08) Kiragu, J.M.Item The Effects of Mangrove Habitat Degradation on Fish Abundance and Diversity in Ungwana Bay-Kenya(Egerton University, 2007-05) David Mirera H.OItem The role of turbidity on picoplankton organic carbon synthesis and growth rates in Lake Baringo ,Kenya(2008-08-04) Olilo, Casianes OwinoWind induced turbidity in Lake Baringo impacts negatively on picoplankton biomass and growth rates. This study investigated the impact of turbidity on picoplankton organic carbon synthesis and growth rates at low (northern), moderate (central) and high sediments disturbance (southern) zones in Lake Baringo. The investigation-followed simple completely randomised design and analysis of variance. Turbidity was measured in the field by a portable turbid meter. Van Dorn was used for field water sample collection. Composite samples of picoplankton from each of the sampling sites were incubated in 3 glass bottles. 100 ml of water were filtered through nuclepore filters using a suction pump to remove predators. Acrdidine orange was used to stain the nuclepore filters. Picoplankton cells were counted under epiflourescence microscope using the frequency of dividing cells technique. Results of this study have shown that picoplankton abundance was strongly and positively related to particulate organic matter (R2 = 0.89; P5 0.004) and dissolved organic carbon (R2 = 0.88; Pfi 0.005) in all the three zones. Specific picoplankton organic carbon synthesis was positively related to the turbidity at the southern (R2 = 0.46; Ps 0.14) and central zones (RZ= 0.47; P$0.l3) but lowest positive relation was observed at the northem zone (R2=0.23, P5033). Picoplankton loss estimates showed strong association with turbidity at the southem (R2=0.503, Ps 0.11) and northen-1 (R2=0.509, P5 0.11) zones, but weak association in the Central zone (R2 I 0.38; P§ 0.19). ln the Southern zone the picoplankton specific growth rates were weakly related to the lake’s water turbidity (R2=0.32, P$ 0.24) while in both northem and central zones there was no link. Picoplankton specific growth rates were strongly and positively related to biological oxygen demand (R2 = 0.56; Pg 0.04) in all the zones. Particulate organic carbon and dissolved organic carbon were strongly and positively related (R2 = 0.99; PS 0.05) in all the zones. These results reassert the phenomenon of energy storage by organic carbon in lake ecosystems. The frequency of dividing cells technique shows that picoplankton organic carbon synthesis, growth rates and the cell division phase of the cell cycle are physiological processes impacted upon and functionally dependent on turbidity. Rainfall influenced these processes with low effects during the dry season (December 2003- March 2004) and high effects during the wet seasons (June 2003-July 2003) in the central, northern and southem zones in ascending order of magnitude. This information is useful for policy appraisal and the management of Lake Baringo fisheries and other freshwater lakes ecosystems with a similar problem of sediments deposits.Item The Impacts of Kisii Municipality and Gesonso COffee Factory Effluents on the Water Quality of River Riana, Kenya(Egerton University, 2008-09) Ombicha, Kariuki SamuelItem The Influence of Community-Based Participatory Monitoring and Evaluation in Environmental Conservation - The Case of Homa Bay District, Kenya(Egerton University, 2008-12) Otieno, Oduwo Alsen.Item Effects of human-wildlife conflicts on the socioeconomic well being of farmers in Taveta Sub-District, Kenya(Egerton University, 2009) Mtunji, Nathaniel KainguItem The impacts of introductions of Cyprinus carpio L.
