Book Description
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?

Book Description
Since the hydrological cycle is so intricately linked to the climate system, any change in climate impacts the water cycle in terms of change in precipitation patterns, melting of snow and ice, increased evaporation, increased atmospheric water vapor and changes in soil moisture and run off. Consequently, climate change could result in floods in some areas and droughts in others resulting in varying availability and the quality of water affects the quality of life, food security and also health security. This book examines the impact of climate change on water as well as health.

Book Description
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.

Book Description
"Climatic Change and Water Resources in the Middle East and North Africa" is dedicated to high-priority topics related to the impact of climate change on water resources in a water scarce region. The subject is described and discussed in three main chapters and different case studies. The three main chapters are (1) Climatic changes - sources and effects on the water cycle, (2) Impact of climate change on water resources, (3) Water resources and water management. These chapters are split up into further 26 sections. A total of 64 individuals from many countries have made contributions to this book. All topics in this book are complimentary and contribute to a comprehensive understanding of the interactions between global climate change, world water cycle and water resources. A valuable and meaningful interdisciplinary mixture of topics is combined in this book which will be of great interest to many scientists.

Book Description
This paper summarizes the methods and findings of the hydrological assessment component of the project studying likely impacts of climate change on water resources and agriculture in Africa. The first phase of the study used a version of a conceptual rainfall-runoff model called WatBal (Water Balance) applied to gridded data to simulate changes in soil moisture and runoff across the whole continent of Africa rather than to any particular catchment or water resource system. The model inputs were the climate variables of the 1961-90 climatology and physiological parameters (such as soil properties and land use) derived from global datasets for each of the 0.5 degree latitude/longitude cells across the continent. The primary model output comprised a time series (monthly time step) of simulated runoff for all the grid cells for each of the districts in the countries of interest. The second phase of the study extended the hydrology analyses to update the above hydroclimatic series to the year 2000 using updated input data. To ascertain the possible impacts of climate change within the districts being investigated this study used synthetic or GCM-based climate change scenarios as input to the WatBal model. The WatBal model was used to determine the impact of these different scenarios on runoff and actual evaporation and hence flow in the districts under study. The generated hydroclimatic series and scenario analyses were used as inputs into various Ricardian regressions in other analyses measuring likely impacts of climate change on the agricultural economies of Africa.

Book Description
Climate change has emerged as the most pressing global challenge of the 21st century and it has a dramatic effect on natural ecosystems and environment. Intelligent mitigation strategies to minimise climate change impacts can result in advanced, novel technologies; healthier aquatic ecosystems and higher food security and well-being for humans. The book includes 45 Chapters by expert authors, covering (i) Hydrometeorology and hydrology, (ii) Natural hazards and disaster risk management, (iii) Aquaculture, (iv) Changing biodiversity scenarios, (v) Capture fisheries, (vi) Food and nutritional insecurity, (vii) Climate change and socio-economic scenarios, and allied areas. It is hoped that this volume will further our understanding and research achievements in the field of climate change and its consequences and facilitate the synthesis of information on how climate-related changes will influence oceans, marine and inland ecosystems, hydrological cycles, fisheries and aquaculture and coastal communities and will be immensely useful to planners, scientists, conservationists, environmentalists, academicians, students and all those who are directly or indirectly involved in the study of impact of climate change and mitigation measures Note: T& F does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.

Book Description
Climate change is a complex long term problem and two centuries in the making. There are only but few human activities that do not contribute to it. Climate change is altering the hydrologic cycle, thus affecting the hydrology and water resources of river basins. This study has been tailored to examine the present and future hydroclimatology of Lower Niger River basin, West Africa. Therefore, the chapters have been designed and developed in a systematic way. The text is arranged in six chapters. Chapter 1 beside introduction to the study discusses the climate-related problems of the Lower Niger Basin, the objective and justification of the study. As well as why the focus of the study is on water and operational definitions. The study draws from various literatures; the same have been discussed in chapter 2. Chapter3 introduces the study area, and discusses the hydrology, topography, weather and climate of the area. Also discussed, is the geology, soil, economic structure, population and settlement, energy and agricultural activities of the area and their interactions with climate. Chapters 4, 5 and 6 discuss the study approach, the results and conclusion respectively.
