The Water of the Jordan Valley


Book Description

Natural saline water, waste water, and irrigation return flow endanger the groundwater aquifers in the Rift. In the long run this will ruin the socio-economic backbone of the settlements in the area. Sustainability of the water resources will only be achieved when the process of water replenishment and its underground flow is understood and water extraction is regionally controlled. Rare earth element and spider patterns are presented as new tools for studying the hydrology. Progress in 3-D modelling of groundwater flow proved successfully the impact of pumping on the surroundings of wells and overexploitation of aquifers.




Sustainable Development in the Jordan Valley


Book Description

This book summarizes the NGO Master Plan that provides a comprehensive program to rehabilitate the Lower Jordan River and its tributaries in Jordan, Israel and Palestine. It is a regional and civil society effort designed to promote the restoration of the valley’s environmental and ecological values within a realistic financial and economic framework. The plan identifies 127 specific regional and national "interventions"(projects) until the year 2050, based on seven strategic planning objectives: pollution control, sustainable water management and river rehabilitation, sustainable agriculture, Jordan River basin governance, ecological rehabilitation, sustainable tourism and cultural heritage development, and urban and infrastructure development. The total investment value is 4.58 billion USD, the plan ranks the interventions and identifies their feasibility in a short, medium and long term investment cycles considering the political environment.




The Dead Sea


Book Description

Located 400 meters below sea level, at the tectonically active irregular boundary between the Mediterranean and Arabic plates, the Dead Sea is the site of many interesting phenomena. It provides a modern analog for ancient pull-apart basins and allows researchers to examine the process of evaporite deposition from deep water. It also offers insight into the adaptive ability of the life form living in the hypersaline brine. This book, based on a conference held in Tel Aviv in December 1993, focuses on the geophysics, geochemistry, hydrology, and climatology of the Dead Sea region.




Society - Water - Technology


Book Description

This book presents the results of the Interdisciplinary Research Group "Society – Water – Technology" of the Berlin-Brandenburg Academy of Sciences and Humanities. It describes interdisciplinary evaluation criteria for major water engineering projects (MWEPs) and portrays an application to the Lower Jordan Valley (Middle East) and the Fergana Valley (Central Asia). Both areas are characterised by transboundary conflicts, by challenges due to demographic and climate change and by political and societal pressures. Based on the findings, the book provides recommendations for science and political decisions makers as well as for international financing institutions. In addition, it outlines research gaps from an interdisciplinary perspective. In the past, MWEPs have been used as an instrument to cope with the demands of growing populations and to enhance development progress. Experiences with MWEPs have shown that a purely technical approach has not always brought about the desired results. In many cases, MWEPs have even resulted in negative implications for society and environment. Therefore, improved management strategies and enhanced technologies for a sustainable water resource management system are a prerequisite to meet present and future challenges. And, moreover, the continuous evaluation and optimisation of these measures is, likewise, a must.




Water Resources in the Middle East


Book Description

This book presents various approaches to the resolution of the severe water resource issues of the Middle East, with particular emphasis on the Israeli-Palestinian water conflicts. The authors include leading Palestinian and Israeli water experts who have worked together on joint research projects aimed at building up mutual understanding and respect. The studies consider the various approaches that could be used to improve cooperation and solve the problems arising from conflicting interests.




The Legacy of Tethys


Book Description

This book is an attempt to present a comprehensive view on the aquatic biogeog raphy of a small but very dynamic and complex area of the globe. Luckily, this area, called here the Levant, has attracted much interest in the past and is being increasingly studied in the present. The interphasing between the knowledge of the historical and formative processes and that of the recent distributional aspects is fairly good. The recent years saw also a widening effort which expressed itself in several symposia and monographic books. Therefore I considered it possible to treat the whole subject of the aquatic biogeography of the Levant singlehandedly rather than in the presently widespread manner of an edited book. I am keenly conscious of the shortcommings of my approach of presenting much second-hand information. Possibly this is being compensated by the fact that this book has a more coherent structure and eventually a clearer scientific message. The effort spent in synthesizing the data from the widely different sources hopefully pays off in a presentation which is more easily comprehended by the average reader. For the suspicious reader, I would recommend to read first the closing chapter of this book in which the quintescence of this book and its message is presented in a summariz ing manner.




Lake Kinneret


Book Description

This condensed volume summarizes updated knowledge on the warm-monomictic subtropical Lake Kinneret, including its geophysical setting, the dynamics of physical, chemical and biological processes and the major natural and anthropogenic factors that affect this unique aquatic ecosystem. This work expands on a previous monograph on Lake Kinneret published in 1978 and capitalizes on the outcome of more than 40 years of research and monitoring activities. These were intensively integrated with lake management aimed at sustainable use for supply of drinking water, tourism, recreation and fishery. The book chapters are aimed at the limnological community, aquatic ecologists, managers of aquatic ecosystems and other professionals. It presents the geographic and geological setting, the meteorology and hydrology of the region, continues with various aspects of the pelagic and the littoral systems. Finally, the last section of the book addresses lake management, demonstrating how the accumulated knowledge was applied in order to manage this important source of freshwater. The section on the pelagic system comprises the heart of the book, addressing the major physical processes, external and internal loading, the pelagic communities (from bacteria to fish), physiological processes and the major biogeochemical cycles in the lake.




Still Waters: The Secret World of Lakes


Book Description

A fascinating exploration of lakes around the world, from Walden Pond to the Dead Sea. More than a century and a half have passed since Walden was first published, and the world is now a very different place. Lakes are changing rapidly, not because we are separate from nature but because we are so much a part of it. While many of our effects on the natural world today are new, from climate change to nuclear fallout, our connections to it are ancient, as core samples from lake beds reveal. In Still Waters, Curt Stager introduces us to the secret worlds hidden beneath the surfaces of our most remarkable lakes, leading us on a journey from the pristine waters of the Adirondack Mountains to the wilds of Siberia, from Thoreau’s cherished pond to the Sea of Galilee. Through decades of firsthand investigations, Stager examines the significance of our impacts on some of the world’s most iconic inland waters. Along the way he discovers the stories these lakes contain about us, including our loftiest philosophical ambitions and our deepest myths. For him, lakes are not only mirrors reflecting our place in the natural world but also windows into our history, culture, and the primal connections we share with all life. Beautifully observed and eloquently written, Stager’s narrative is filled with strange and enchanting details about these submerged worlds—diving insects chirping underwater like crickets, African crater lakes that explode, and the growing threats to some of our most precious bodies of water. Modern science has demonstrated that humanity is an integral part of nature on this planet, so intertwined with it that we have also become an increasingly powerful force of nature in our own right. Still Waters reminds us how beautiful, complex, and vulnerable our lakes are, and how, more than ever, it is essential to protect them.




Quaternary of the Levant


Book Description

Quaternary of the Levant presents up-to-date research achievements from a region that displays unique interactions between the climate, the environment and human evolution. Focusing on southeast Turkey, Lebanon, Syria, Jordan and Israel, it brings together over eighty contributions from leading researchers to review 2.5 million years of environmental change and human cultural evolution. Information from prehistoric sites and palaeoanthropological studies contributing to our understanding of 'out of Africa' migrations, Neanderthals, cultures of modern humans, and the origins of agriculture are assessed within the context of glacial-interglacial cycles, marine isotope cycles, plate tectonics, geochronology, geomorphology, palaeoecology and genetics. Complemented by overview summaries that draw together the findings of each chapter, the resulting coverage is wide-ranging and cohesive. The cross-disciplinary nature of the volume makes it an invaluable resource for academics and advanced students of Quaternary science and human prehistory, as well as being an important reference for archaeologists working in the region.
