This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a critical analysis of the water quality changes and their impacts on water resources within the Athi River Catchment and its implications of the people,Äôs livelihoods. The paper analyses the effects of land use activities on water quality in the headwater areas of the basin which has a profound impacts on the downstream water uses within the basin. The paper in addition makes an attempt to relate the impacts of human activities on water quality degradation trends within the basin against the available and potential water resources in the basin. The Athi River is the second largest in Kenya and traverses areas of diverse land use activities from the more agricultural head water areas through the industrial hub of Kenya in Nairobi to the Indian Ocean discharging its waters near Malindi town north of Mombasa. The paper gives a detailed analysis of the impacts of human activities on the water resources in regard to water quality degradation, pollution and mitigation measures. The study was based on field data collection and measurements and laboratory analysis. The researcher used 10 sampling points located within the Nairobi sub-basin and distributed along the river profile to examine the trends in water quality degradation and its implication on human livelihoods in the basin. The researcher noted a declining trend in water quality status downstream the river profile. A close analysis of the water situation in the basin paints a blink future on the available water resources in the basin against the projected water uses and increasing population compounded by the impacts of water pollution and climate change. This is likely to increase incidences of water shortage and food insecurity in many parts of the basin. The researcher recommends more investments in water harvesting infrastructure, environmental conservation and adoption of modern water management technologies.

Book excerpt: This book provides a comprehensive overview of the factors and impacts influencing water quality in various locations worldwide. It discusses the use of new analytical and monitoring methods and novel technologies for decontamination and protection of polluted waters. It includes three sections that discuss monitoring and assessment of water quality, factors of water quality degradation, and methods for water quality improvement. Water quality is a global environmental concern affecting the socioeconomic development and functionality of various ecosystems. The protection of water quality requires adequate monitoring and assessment methods included in reliable watershed management plans.

Book excerpt: Africa's high dependence upon natural resources makes the continent particularly vulnerable to changes in the availability of water as a result of climate changes. In this study, the vulnerability of water resources to environmental change is assessed on a river/lake/groundwater basin scale for the Southern, Eastern, Western and Northern African regions.

This book was released on 2015-06-01 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ‘WISE-UP to climate’ project aims to demonstrate the value of natural infrastructure as a ‘nature-based solution’ for climate change adaptation and sustainable development. Within the Tana River Basin, both natural and built infrastructure provide livelihood benefits for people. Understanding the interrelationships between the two types of infrastructure is a prerequisite for sustainable water resources development and management. This is particularly true as pressures on water resources intensify and the impacts of climate change increase. This report provides an overview of the biophysical characteristics, ecosystem services and links to livelihoods within the basin.

This book was released on 2017-11-06 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the apparently desperate situation of sub-Saharan Africa, rainwater harvesting and management is a viable intervention for upgrading rain-fed agriculture, improving water supply and sustainable livelihoods in water-scarce river basins. If strategies are developed to ensure equity allocation of basin water, a win-win situation for diverse water users can be achieved. This thesis assesses the hydrological impacts of land use changes on water resources management and socio-economic development of the upper Ewaso Ng�iro river basin in Kenya. It considers the impact of irrigation on dry season river flows and highlights the challenge of flood storage strategies. While flood storage can reduce dry season irrigation water abstractions by more than a half, without affecting hydro-ecological functions downstream, unplanned flood harvesting may impact negatively on flood flow, being detrimental to natural ecosystems and groundwater downstream.

Available in PDF, EPUB and Kindle. Book excerpt: The deterioration of water quality threatens the functioning of ecosystems and the sustainability of socioeconomic growth and development more especially for a water-stressed country like South Africa (SA). The Olifants river basin, which is one of the nine water management areas in SA, faces serious water scarcity, with declining surface and groundwater quality due to pollution from mining activities, irrigation agriculture, and industrial waste disposal. This has led to great competition for water among different economic sectors and between upstream and downstream users. As a result, the government has implemented a series of pollution control measures with the view to mitigating pollution and water shortage in the basin. This study developed and used a regional, environmental, computable general equilibrium (CGE) model to assess the environmental, economic, and social impacts of protecting the basin"Ë−s water resources. To calibrate the model, the study also constructed an environmental social accounting matrix (ESAM) using the framework of an environmentally extended SAM. Results of the environmental and economic impacts of taxing water pollution suggest that internalising the negative externality of water pollution in the Olifants river basin will effectively reduce pollution discharge (i.e., achieve its environmental goals). This, however, comes at some costs to the regional economy of the basin. The economic burden of the tax happens to be fairly small though, due to the small relative share of the water pollution supply and abatement costs in total production costs. Furthermore, recycling the tax revenue through income transfers to households or a subsidy to pollution abatement mitigates the adverse economic impacts. Results of the distributional impacts of taxing water pollution in the basin indicate that the water pollution tax is progressive (inequity and poverty-reducing) on the income side as the poorest and vulnerable derive lower shares of their income from capital, which bears the biggest burden of the tax. On the expenditure side, however, the tax is regressive (inequity and poverty increasing), due to the higher share of pollution-intensive goods in poor households"Ë−expenditure. The net effect of the tax is, however, not pro-poor. Recycling the tax revenue through a subsidy to pollution abatement sectors reduces the adverse effect of the tax on household welfare whereas uniform direct lump-sum transfers to households"Ë−income results in a progressive outcome. This study has demonstrated the importance of using an integrated framework that allows non-linear substitution possibilities and endogenous price determination to account for both the direct and indirect costs of water quality management policies. The findings should, however, be viewed with caution due to some limitations inherent in basic assumptions of this study. Firstly, demand for pollution abatement services by production sectors, is specified in a simple way using exogenously determined clean-up rates and the assumption that unit costs of pollution abatement are fixed. Secondly, this study did not account for the economic benefits from water quality improvements as well as from technological advancements that lead to reduced pollution intensities.
