Download or read book Managing Basin Interdependencies in a Heterogeneous, Highly Utilized and Data Scarce River Basin in Semi-Arid Africa written by Jeremiah Kipkulei Kiptala and published by CRC Press. This book was released on 2020-04-30 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: For integrated water resources management both blue and green water resources in a river basin and their spatial and temporal distribution have to be considered. This is because green and blue water uses are interdependent. In sub-Saharan Africa, the upper landscapes are often dominated by rainfed and supplementary irrigated agriculture that rely on green water resources. Downstream, most blue water uses are confined to the river channels, mainly for hydropower and the environment. Over time and due to population growth and increased demands for food and energy, water use of both green and blue water has increased. This book provides a quantitative assessment of green-blue water use and their interactions. The book makes a novel contribution by developing a hydrological model that can quantify not only green but also blue water use by many smallholder farmers scattered throughout the landscape. The book provides an innovative framework for mapping ecological productivity where gross returns from water consumed in agricultural and natural vegetation are quantified. The book provides a multi-objective optimization analysis involving green and blue water users, including the environment. The book also assesses the uncertainty levels of using remote sensing data in water resource management at river basin scale.

Download or read book Improved Hydrological Understanding of a Semi-Arid Subtropical Transboundary Basin Using Multiple Techniques - The Incomati River Basin written by Saraiva Okello and published by CRC Press. This book was released on 2019-05-13 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study aims at improving the hydrological process understanding of the semi-arid and transboundary Incomati river basin to enable better water management. Comprehensive statistical and trend analysis of rainfall and streamflow were conducted, and the Indicators of Hydrological Alteration tool was deployed to describe the streamflow regime and trends over time. Land use and land cover change, particularly the conversion of natural vegetation into forest plantation, the expansion of irrigated agriculture and the flow regulation due to dam operation were identified as critical drivers of flow regime alteration. Hydrograph separation using long-term hydrochemical data at seasonal scale, and hydrochemical and isotope data at event scale were performed to quantify runoff components. A novel methodology to calibrate recursive digital filters using routinely collected water quality data was developed and tested in the catchment. This method allows for estimation of daily baseflow from readily available daily streamflow data. Dominant runoff generation zones were mapped using the Height Above Nearest Drainage approach. The hydrological model STREAM was then employed, informed by the runoff generation zones mapping and the process understanding gained in the catchment, as well as remote sensing data. The study provides the basis for better operational water management in the catchment.

Book Synopsis Sustainability of Engineered Rivers In Arid Lands by : Jurgen Schmandt
Download or read book Sustainability of Engineered Rivers In Arid Lands written by Jurgen Schmandt and published by Cambridge University Press. This book was released on 2021-09-16 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This interdisciplinary volume examines how nine arid or semi-arid river basins with thriving irrigated agriculture are doing now and how they may change between now and mid-century. The rivers studied are the Colorado, Euphrates-Tigris, Jucar, Limarí, Murray-Darling, Nile, Rio Grande, São Francisco, and Yellow. Engineered dams and distribution networks brought large benefits to farmers and cities, but now the water systems face multiple challenges, above all climate change, reservoir siltation, and decreased water flows. Unchecked, they will see reduced food production and endanger the economic livelihood of basin populations. The authors suggest how to respond to these challenges without loss of food production, drinking water, or environmental health. The analysis of the political, hydrological, and environmental conditions within each basin gives policymakers, engineers, and researchers interested in the water/sustainability nexus a better understanding of engineered rivers in arid lands.
Book Synopsis Decentralization of River Basin Management by :
Download or read book Decentralization of River Basin Management written by and published by World Bank Publications. This book was released on 2005 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decentralization and increased stakeholder involvement have been major elements of water sector reform as ways to promote sustainable and integrated resource management particularly of river basins. Based on an analytical framework for relating decentralization and stakeholder involvement to improved river basin management, this paper infers several hypotheses about factors associated with greater or lesser likelihood of success of the decentralization process using data from 83 river basins worldwide. The results suggest that physical, political, economic, financial, and institutional characteristics of the basin do affect the process and the level of performance of the decentralization. In particular, the presence of water scarcity may be a stimulus to reform, uniting the stakeholders in the basin and leading to better performance; organized user groups push for the initiation of decentralization reforms but may be associated with costs to the process and difficulty of achieving decentralization; the existence of dispute resolution mechanisms supports stakeholder involvement and improves decentralization performance; where stakeholders accepted greater financial responsibility, complying with tariffs and contributing to the budget for basin management, the decentralization process and performance measures increased; basins with higher percentages of their budgets from external governmental sources benefited from better stability and support and it shows in the performance of the decentralization process.
Book Synopsis Institutional and Policy Analysis of River Basin Management by :
Download or read book Institutional and Policy Analysis of River Basin Management written by and published by World Bank Publications. This book was released on 2005 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The authors describe and analyze river basin management in the Guadalquivir River Basin in Spain. The Guadalquivir river flows westerly across southern Spain, with nearly all of its 57,017 km2 drainage area within the region of Andalusia. Water management issues in this semi-arid, heavily agricultural, but rapidly urbanizing region include drought exposure, water allocation, water quality, and in some areas, groundwater overdraft. A river basin agency (Confederacion Hidrografica del Guadalquivir, or CH Guadalquivir) has existed within the basin since 1927, but its responsibilities have changed substantially over its history. For much of its life, CH Guadalquivir's mission was water supply augmentation through construction and operation of reservoirs, primarily to support irrigation, under central government direction with little provision for water user participation. Following the Spanish political system's transformation and Spain's accession to the European Union, water law and policy changes greatly expanded CH Guadalquivir's responsibilities and restructured it to incorporate representation of some basin stakeholders. Although the basin agency's accomplishments in reservoir construction have been prodigious, its record of performance with respect to its newer responsibilities has been mixed, as have perceptions of its openness and responsiveness to basin interests other than irrigators. This paper--a product of the Agriculture and Rural Development Department--is part of a larger effort in the department to approach water policy issues in an integrated way. The study was funded by the Bank's Research Support Budget under the research project "Integrated River Basin Management and the Principle of Managing Water Resources at the Lowest Appropriate Level: When and Why Does It (Not) Work in Practice?""--World Bank web site.

Book Synopsis Managing Water Resources in Large River Basins by : William Young
Download or read book Managing Water Resources in Large River Basins written by William Young and published by MDPI. This book was released on 2021-05-07 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Management of water resources in large rivers basins typically differs in important ways from management in smaller basins. While in smaller basins the focus of water resources management may be on project implementation, irrigation and drainage management, water use efficiency and flood operations; in larger basins, because of the greater complexity and competing interests, there is often a greater need for long-term strategic river basin planning across sectors and jurisdictions, and considering social, environmental, and economic outcomes. This puts a focus on sustainable development, including consumptive water use and non-consumptive water uses, such as inland navigation and hydropower. It also requires the consideration of hard or technical issues—data, modeling, infrastructure—as well as soft issues of governance, including legal frameworks, policies, institutions, and political economy. Rapidly evolving technologies could play a significant role in managing large basins. This Special Issue of Water traverses these hard and soft aspects of managing water resources in large river basins through a series of diverse case studies from across the globe that demonstrate recent advances in both technical and governance innovations in river basin management.

Book Synopsis Comparison of Institutional Arrangements for River Basin Management in Eight Basins by : William Andrew Blomquist
Download or read book Comparison of Institutional Arrangements for River Basin Management in Eight Basins written by William Andrew Blomquist and published by World Bank Publications. This book was released on 2005 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study represents an effort toward understanding conditions that affect successful or unsuccessful efforts to devolve water resource management to the river basin level and secure active stakeholder involvement. A theoretical framework is used to identify potentially important variables related to the likelihood of success. Using a comparative case-study approach, the study examined river basins where organizations have been developed at the basin scale and where organizations perform management functions such as planning, allocation, and pricing of water supplies, flood prevention and response, and water quality monitoring and improvement. This paper compares the alternative approaches to basin governance and management adopted in the following river basins: the Alto-Tiete and Jaguaribe River Basins, Brazil; the Brantas River Basin, East Java, Indonesia; the Fraser River Basin, British Columbia, Canada; the Guadalquivir Basin, Spain; the Murray-Darling River Basin, Australia; the Tarcoles River Basin, Costa Rica; and the Warta River Basin, Poland. The analysis focuses on how management has been organized and pursued in each case in light of its specific geographical, historical, and organizational contexts and the evolution of institutional arrangements. The cases are also compared and assessed for their observed degrees of success in achieving improved stakeholder participation and integrated water resources management.

Book Synopsis Catchment and River Basin Management by : Laurence Smith
Download or read book Catchment and River Basin Management written by Laurence Smith and published by Routledge. This book was released on 2015-04-17 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The central focus of this volume is a critical comparative analysis of the key drivers for water resource management and the provision of clean water – governance systems and institutional and legal arrangements. The authors present a systematic analysis of case study river systems drawn from Australia, Denmark, Germany, the Netherlands, UK and USA to provide an integrated global assessment of the scale and key features of catchment management. A key premise explored is that despite the diversity of jurisdictions and catchments there are commonalities to a successful approach. The authors show that environmental and public health water quality criteria must be integrated with the economic and social goals of those affected, necessitating a 'twin-track' and holistic (cross-sector and discipline) approach of stakeholder engagement and sound scientific research. A final synthesis presents a set of principles for adaptive catchment management. These principles demonstrate how to integrate the best scientific and technical knowledge with policy, governance and legal provisions. It is shown how decision-making and implementation at the appropriate geographic and governmental scales can resolve conflicts and share best sustainable practices.
