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
Remote Sensing of Climate provides cutting-edge techniques in remote sensing of climate variability and the environment. The book focuses on methods and data analytics, advancements in scientific research in the field, and further proffers recommendations on the possible knowledge gaps and future scientific research directions. It covers eight key themes of remote sensing and climate variability, including discussions on how the various aspects from each chapter of the themes interrelate. It also integrates several divergent perspectives on remote sensing and climate variability and the environment to show the interrelationships between the perspectives. This is an important reference for those in education and research working on remote sensing and climate science who need methods, data analytics, case studies, research strides, and key knowledge gaps in the field. - Discusses advancements and future research directions in remote sensing for climate variability in a variety of environments - Includes simplified and condensed methodologies and data analytics - Provides case studies on remote sensing of climate variability, both of the Northern hemisphere temperate systems which are little affected by climate variability, and the greater-impacted global south

Book Description
The Volta River is one of the major rivers in Africa. In this study, a dynamic regional climate model (CCLM), a hydrological model (SWAT) and a water resource model (WEAP) were used to provide an assessment of one downscaled ‘middle impact’ climate change scenario on the performance of existing and planned irrigation and hydropower schemes. The results indicate that, by the middle of the twenty-first century, altered climate is likely to undermine the technical performance of existing and planned reservoirs, which will, in turn, affect development outcomes. Future water resources development in the basin requires interventions that bolster resilience and water security. Much more systematic planning of water storage, greater cooperation between the riparian states and consideration of innovative approaches to water storage are needed.

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
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?
