Book Description
The idea for this book was born at the June 1996 meeting of the IDEAL Steering Committee in Milwaukee, Wisconsin. We had just completed a successful and stimulating special symposium during the annual meeting of the American Society for Limnology and Oceanography, and enthusiasm was running high for the production of a volume that could assemble in one place the scientific findings that were starting to emerge from East Africa. IDEAL, an International Decade for the East African Lakes, had ended one round of field investigations, many of which had been centered on Lake Victoria. As the climatologists, geologists, paleolimnologists, and biologists displayed their results and debated interpretations, it appeared that some paradigms were shifting, and that new explanations of climate history and modem processes were taking shape. The Steering Committee endorsed the production of a volume that would draw together the different research results that were emerging and which would be representative of the scope of science issues that exist within IDEAL. This book follows in the spirit of The Limnology, Climatology, and Paleoclimatology of the East African Lakes, published in 1996, but has a somewhat different purpose. The previous publication also included original science results, but it was conceived to review the state of knowledge, identify critical problems, and point to new paths of inquiry. It accompanied the development of our first Science and Implementation Plan for the East African Lakes.

Book Description
The Second International Symposium on the East African Lakes was held from 10-15 January 2000 at Club Makokola on the southern shore of Lake Malawi. The symposium was organized by the International Decade for the East African Lakes (IDEAL), a research consortium of African, European and North American scientists interested in promoting the investigations of African Great Lakes as archives of environmental and climatic dynamics. Over one hundred African, European and North American scientists with special expertise in the tropical lakes participated in the symposium which featured compelling presentations on the limnology, climatology, palaeoclimatology and biodiversity of the East African Lakes. It is their papers that comprise this book. The large lakes of East Africa are important natural resources that are heavily utilized by their bordering countries for transportation, water supply, fisheries, waste disposal, recreation and tourism. The lakes are unique in many ways: they are sensitive to climatic change and their circulation dynamics, water-column chemistry and biological complexity differ significantly from large lakes at higher latitudes; they have long, continuous, high resolution records of past climatic change; and they have rich and diverse populations of endemic organisms. These unique properties and the significance of the palaeolimnological records demand and attract research interest from around the world.

Book Description
The book presents results of the Defragmenting African Resource Management (DARMA) Project covering the Lake Chilwa basin in Malawi. The central theme is that, in order to ensure resource base sustainability, research and management within the basin should adopt an ecosystems approach. Presently, research and management of the basin is sector-based, hence resource user conflicts are increasing. User demand for various resources is increasing rapidly, mainly due to population increase and lack of alternative economic activities, thereby presenting challenges to sustainable resource management. Specific areas of sectoral interconnections are highlighted and defragmentation options suggested. (Series: Defragmenting African Resource Management [DARMA] - Vol. 1)

Book Description
This book focuses on two complementary time-scales, the Holocene (approximately the last 11,500 years) and the last glacial-interglacial cycle (approximately the last 130,000 years) to synthesize evidence of climate variability at the regional and continental scale across Europe and Africa. This is the first examination of historical climate variations at such a scale, and thus sets a benchmark for future research.

Book Description
What have we learnt about the Nile since the mid-1970s, the moment when Julian Rzóska decided that the time had come to publish a comprehensive volume about the biology, and the geological and cultural history of that great river? And what changes have meanwhile occurred in the basin? The human popu- tion has more than doubled, especially in Egypt, but also in East Africa. Locally, industrial development has taken place, and the Aswan High Dam was clearly not the last major infrastructure work that was carried out. More dams have been built, and some water diversions, like the Toshka lakes, have created new expanses of water in the middle of the Sahara desert. What are the effects of all this on the ec- ogy and economy of the Basin? That is what the present book sets out to explore, 33 years after the publi- tion of “The Nile: Biology of an Ancient River”. Thirty-seven authors have taken up the challenge, and have written the “new” book. They come from 13 different countries, and 15 among them represent the largest Nilotic states (Egypt, Sudan, Ethiopia, Uganda, and Kenya). Julian Rzóska died in 1984, and most of the - authors of his book have now either disappeared or retired from research. Only Jack Talling and Samir Ghabbour were still available to participate again.

Book Description
This book is useful to those in water resources management and policy formulations, hydrologists, environmentalists, engineers and researchers. Exploiting advanced statistical techniques and the latest state-of-the-art multi-mission satellites, surface models and reanalysis products, this book provides the first comprehensive weighing of the changes in the Nile River Basin’s (NRB: ~ 3,400,000 km2 ) stored waters' compartments, surface, soil moisture and groundwater, and their association to climate variability/change and anthropogenic impacts on the one hand. On the other hand, it argues on the need for equitable use of the NRB’s waters by all 11 countries within its basin, and doing away with obsolete Nile treaties that were signed by Britain, Egypt and Sudan, which prohibit the use of the Nile by 8 upstream countries. With Ethiopia’s construction of Africa’s largest dam (GERD; Grand Ethiopian Renaissance Dam) along the Blue Nile, which is expected to take several years to fill, the Nile is back on the news. Combined with Uganda’s Nalubaale, Kiira and Bujagali dams on the White Nile, these human-induced impacts (i.e., damming), coupled with those of climate variability/change, are expected to exacerbate tension with the low stream countries (Egypt and Sudan) fearing the cut in theNile’s total volume. Furthermore, the Nile river, arguably the world’s longest river (6800 km), impacts on the livelihood of over 300 million people of 11 countries within its basin. This population is expected to double in the next twenty-five years, thereby putting extreme pressure on its water resources. An in-depth analysis of changes in the Nile’s stored waters, therefore, is essential to inform its management and sustainable equitable use. Owing to its sheer size, however, obtaining in-situ data from “boots on the ground” is practically impossible, paving way to the space-based weighing of the Nile River Basin using a suite of high spatio-temporal remotely sensed and reanalysis products, as well as those of hydrological models. “Arguably, the Nile River is the most unique river in the world. It spans extremes of rainfall from being measured by meters to being measured by centimeters, from the humid tropics to the driest of deserts. Yet, thirsty people live throughout this basin and therefore the demands on its water resources are uneven. Knowing the water amounts throughout the entire Nile Basin is a critical step for governments and international treaties to avoid the “Tragedy of the Commons”. Africa can embrace this future through the leadership of Prof. Awange and others like him who have devoted their careers to Africa’s waters” —Doug Alsdorf, Ph.D., Professor of Geophysics at the Ohio State University (USA).

Book Description
The Quaternary evolution of Kenya is set in a dynamic climatic, environmental, volcanic and tectonic context. Climate has been controlled by orbital forcing with a dominant precessional cycle of 23,000 years driving hydrological changes that have had dramatic impacts on lake levels. Climate has interacted with tectonism and volcanism to continually modify the landscapes and environments, partly influencing hominin, animal and plant evolution. The most prominent feature is the Rift Valley, whose evolution was associated with flood volcanism, rift deformation and migration, formation of caldera volcanoes and the rise and establishment of many lakes, up to about 0.3 Ma. In the western part of the country, Lake Victoria arose in the Middle Pleistocene as a consequence of rift margin uplift and resulting river reversal and ponding. In the eastern part of the country, the landscape is dominated by the Plio-Pleistocene evolution of Mount Kenya and the Nyambeni Volcanic Series which comprises of a large field of basaltic cones and vents that extend to the arid to semi-arid northern part of the country. Several factors such as the tectonic evolution, climate, wave and tidal regime, marine transgressions and regressions, sedimentation and river discharge control the geomorphology of the Kenyan coast. Geomorphological features include dune sands, coral reefs and terraces which indicate that sea level was above present levels at least four times during the Pleistocene.
