This book was released on 2018-03-14 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Demand for land and water for agriculture, urbanization, irrigation, hydropower, and industrialization is increasing to meet the demands of growing populations and of growing economies. However, changes in land and water resources are often studied separately. A better representation of the interaction between land-use change and its drivers on the one hand and water resources on the other is imperative for sustainable environmental management. This research investigates and develops spatial analysis methods and tools for the quantification of dynamic feedbacks between land-use change and water resources, by focusing on case study catchments in Ethiopia and South Africa. Furthermore, the research investigates methods for analysing land-use suitability and modelling land-use change. Results show that major changes in land-use have been observed in the past two to three decades in the study catchments. Model representation of the interaction between land-use change and water resources shows that changes in land-use influence hydrologic responses. These influences are especially pronounced during high- and low-flow seasons. Likewise, hydrologic processes and water resources availability influence land-use suitability and hence land-use change responses. Accounting for the dynamic feedback between land-use and hydrology thus produces improved knowledge that can better inform integrated natural resources management.

Download or read book Impacts of Global Change on the Hydrological Cycle in West and Northwest Africa written by Peter Speth and published by Springer Science & Business Media. This book was released on 2010-08-12 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: Africa is highly vulnerable to the impacts of climate change. In particular shortage of fresh water is expected to be the dominant water problem for West and Northwest Africa of the 21th century. In order to solve present and projected future problems concerning fresh water supply, a highly interdisciplinary approach is used in the book. Strategies are offered for a sustainable and future-oriented water management. Based on different scenarios, a range of management options is suggested with the aid of Information Systems and Spatial Decision Support Systems for two river catchments in Northwest and West Africa: the wadi Drâa in south-eastern Morocco and the Ouémé basin in Benin. The selected catchments are representative in the sense: "what can be learnt from these catchments for other similar catchments?

Download or read book Climate Change and Water Resources in Africa written by Salif Diop and published by Springer Nature. This book was released on 2021-02-15 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this book is on the key water-related vulnerabilities to climate change in Africa, particularly in its most vulnerable areas, exploring potential management responses to such vulnerabilities. The African countries are particularly exposed and vulnerable to the negative impacts of climate change, with important impacts on water resources and hydrological systems, water availability, water resource management and sea level variations. Already, under various anthropogenic pressures, the status of water resources in Africa has been changing over the past decades, with decreasing water quality, falling groundwater levels, and variability in rainfall, both in terms of timing and intensity. Climate change will further accelerate the rate of change, affecting the ability of people and societies to respond in a timely manner. It is clear that there is no quick fix to the pressures imposed on water resources by climate change. Increasing the resilience of ecosystems and communities to extreme events such as flooding and drought, and integrating climate change risks and opportunities into development decision-making is indeed a key challenge, as much a technical climate-change one, as a political and developmental challenge. The book, in this regard, intends to contribute to the debate around climate change in relation to water resources management in Africa, and in particular inform policy decisions and actions that will improve governments’ and communities’ ability to manage the challenges of climate change and variability in relation to the aquatic ecosystems that they depend on. The knowledge collected in this book will benefit policy makers, researchers, as well as other stakeholders.

This book was released on 2015-01-29 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: The central theme of this book is focused on the analyses and the results which emerged from the international research project BRAHMATWINN sponsored by European Commission (EC) and conducted during 2006 – 2009. The book highlights the achievements of BRAHMATWINN to carry out a harmonised integrated water resources management (IWRM) approach as addressed by the European Water Initiative (EWI) in headwater river systems of alpine mountain massifs. The latter are already impacted from climate change, and the BRAHMATWINN project established transfer of professional IWRM expertise, approaches and tools based on case studies carried out in twinning European and Asian river basins. The project addresses all important IWRM issues in a balanced way, including conflict resolution in the trans- boundary Danube and Brahmaputra River Basins in Europe and South Asia respectively. This book will be useful to researchers, professionals, managers and decision makers associated with study and application of sustainable integrated land and water resources management (ILWRM) in the backdrop of climate change.

Download or read book Modelling Water Resource Management in Lake Naivasha written by Amani Alfarra and published by LAP Lambert Academic Publishing. This book was released on 2010-06 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling Lake Naivasha, Kenya and its surroundings is an issue of very high significance because of great socio-cultural, ecological and economic values. The basin comprises a biosphere reserve, a national park with a variety of wildlife, a significant livestock activity, a very fertile land for agriculture and a growing tourism industry. The prevailing system of uncoordinated water resources management in the basin cannot sustain the ever-increasing water needs of the various expanding sectors. Therefore a strategy must be sought to integrate the various sectoral needs against the available water resources in order to attain both economic and ecological sustainability. The study attempts to develop, for the first time in the Lake Naivasha Basin, an integrated water resource management model. In order to understand the situation in the whole catchment and identify where problems exist and the weakness that affect the catchment and their improvement.

Download or read book Hydrological Modelling in Arid and Semi Arid Areas written by Howard Wheater and published by Cambridge University Press. This book was released on 2007-11-22 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arid and semi-arid regions are defined as areas where water is at its most scarce. The hydrological regime in these areas is extreme and highly variable, and they face great pressures to deliver and manage freshwater resources. However, there is no guidance on the decision support tools that are needed to underpin flood and water resource management in arid areas. UNESCO initiated the Global network for Water and Development Information for arid lands (GWADI), and arranged a workshop of the world's leading experts to discuss these issues. This book presents chapters from contributors to the workshop, and includes case studies from the world's major arid regions to demonstrate model applications, and web links to tutorials and state-of-the-art modelling software. This volume is a valuable reference for researchers and engineers working on the water resources of arid and semi-arid regions.

Download or read book Managing Water Resources in a Time of Global Change written by Alberto Garrido and published by Routledge. This book was released on 2009-01-13 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global change possesses serious challenges for water managers and scientists. In mountain areas, where water supplies for half of the world population originate, climate and hydrologic models are still subject to considerable uncertainty. And yet, critical decisions have to be taken to ensure adequate and safe water supplies to billions of people, millions of farmers and industries, without further deteriorating rivers and water bodies. While global warming is known to cause glaciers’ retreat and reduced snow packs around the world, it is not clear that mountain discharge will be lower. What is widely recognised is that water management must be adapted to accommodate significant regime changes. However, this inevitably involves managing transboundary rivers, adding further complexity to putting principles in practice. This book takes global warming and the importance of mountain areas in world water resources as the starting point. First, it provides detailed reviews of the processes going on in several rivers systems and world regions in Europe (Rhône and Ebro), North America (Canadian Rockies, Western US and Mexico), the Middle East (Jordan), Africa (Tunisia, Kenya and South Africa). These contexts provide case studies and examples that show the difficulties and potential for adaptation to global change. Land-use, economics, numerous modeling approaches are some of the cross-cutting issues covered in the chapters. The volume also includes the views of water practitioners, with two chapters authored by members of the US-Canada International Joint Commission, an industrialist from Western Canada and an environmental leader in Spain. By combining a rich set of contexts and approaches, the volume succeeds in offering a view of the global challenges faced by water agencies, international donors and researchers around the world. A case is made in some chapters to seek adaptive strategies rather than trying to reduce or control resources variability. This requires factoring in land-use, social and economic aspects, especially in developing countries. Another conclusion is that complex problems can and must be posed and negotiated with the help of models, mapping techniques and science-based facts. However complex these may be, there are ways to translate them to easily interpretable and visualisations of alternative scenarios and courses of action. This book provides numerous examples of the potential of such approaches to draft environmental programmes solve transboundary disputes and reduce the economic consequences of droughts and climate instability.
