Enhancing response farming for improved strategic and tactical agronomic management of risks of seasonal rainfall variability

Abstract Seasonal rainfall variability, particularly the uncertainty with respect to the direction and extent that variability will assume in a given season, forms the greatest source of risk to crop production in semi-arid areas of Ethiopia. Equipping vulnerable communities, in advance, with the expected date of onset of a cropping season, is crucial for smallholder farmers to better prepare to respond and manage the uncertainties. Therefore, rainfall prediction, particularly development of...

Development of a Water Quality Assessment Index for the Chania River, Kenya

Abstract Human-related activities are known to have deleterious effects on the water quality of aquatic ecosystems, but there is limited information on the impact of these on rivers in tropical regions, such as the Chania River in Kenya. The Chania River is an important source of water for humans and animals and provides habitat for a variety of flora and fauna. This study used a Water Quality Index (WQI) to assess the suitability of the water for human use based on selected physico-chemical...

Water resource management: IWRM strategies for improved water management.

Abstract Objective The analytical study systematically reviewed the evidence about the IWRM strategy model. The study analysed the IWRM strategy, policy advances and practical implications it had, since inception on effective water management in East, West and Southern Africa. Methods The study adopted the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols (PRISMA-P) and the scoping literature review approach. The study searched selected databases for peer-reviewed a...

Challenges Facing Small and Medium Water Service Providers in Kenya: A Case of Amatsi Water Services Company, Vihiga County

Abstract The access to water services is a fundamental human right. Water and sanitation services coverage in Kenya is low even with the implementation of reforms in the sector initiated in 2002. Small and medium Water Service Providers (WSP) face numerous challenges which are stifling their ability to sustainably fulfill their mandates without relying on subsidies from state or non-state entities. The aim of this study was to analyze the challenges facing water utilities in rural Counties u...

Application of Artificial Neural Network Model In Forecasting Water Demand: Case of Kimilili Water Supply Scheme, Kenya.

Abstract Potable water treatment and supply systems are designed and constructed to deliver adequate water to meet consumer demand requirements. Consequently, water demand forecasting is essential for the design and operations management of treated water supply systems. Correct prediction of time-varying water demand trends and the critical water demand values determines the extent to which a network can satisfy critical demand and maintain economic efficiency. This study aimed to forecast K...

The study of the effects of Mau Catchment Degradation on the Flow of the Mara River, Kenya

Abstract: The Mara River is the lifeline of the Trans boundary Mara basin across Kenya and Tanzania. The basin is considered one of the more serene sub-catchments of the Lake Victoria Basin and ultimately the Nile Basin. The basin traverses the famous Maasai Mara and Serengeti National Parks in Kenya and Tanzania respectively. The basin also contains forests, largescale farms, smallholder farms, pastoral grazing lands, as well as hunter gatherers and fishers. There is growing concern however...

Defluorination Of Drinking Water Using Coalesced And Un Coalesced Mica

Abstract This is a sorption study that focused on the use of mica clay mineral grouped into mica untreated, activated mica at 800 °C, mica impregnated separately with iron and aluminium for defuoridation of water. In this study, characterization of adsorbent was done by using XRF and XRD and quantifcation of fuoride by using fuoride ion selective electrode. Characterization of adsorbent showed the presence of SiO2, CaO, P2O5, Fe2O3 and Al2O3 in the adsorbent. XRD exhibited higher compositi...

Investigation on Poor Water Quality Supply in Calabar: A Case Study of Cross River State Water Board

Increase in population and change in lifestyle has created water scarcity in many parts of the country. Microstructures for rainwater harvesting, artificial recharge and reuse of water are becoming more and more popular to solve the local water problems, to mitigate water shortage and improve water quality. The study was conducted to investigate the challenges influencing the implementation of water sector reforms in Cross River State Water Board Limited and to address the poor water quality ...
