Rivers under Siege is a wrenching firsthand account of how human interventions, often well intentioned, have wreaked havoc on West Tennessee's fragile wetlands. For more than a century, farmers and developers tried to tame the rivers as they became clogged with sand and debris, thereby increasing flooding. Building levees and changing the course of the rivers from meandering streams to straight-line channels, developers only made matters worse. Yet the response to failure was always to try to subdue nature, to dig even bigger channels and construct even more levees-an effort that reached its sorry culmination in the U.S. Army Corps of Engineers' massive West Tennessee Tributaries Project during the 1960s. As a result, the rivers' natural hydrology descended into chaos, devastating the plant and animal ecology of the region's wetlands. Crops and trees died from summer flooding, as much of the land turned into useless, stagnant swamps. The author was one of a small group of state waterfowl managers who saw it all happen, most sadly within the Obion-Forked Deer river system and at Reelfoot Lake. After much trial and error, Johnson and his colleagues in the Tennessee Wildlife Resources Agency began by the 1980s to abandon their old methods, resorting to management procedures more in line with the natural contours of the floodplains and the natural behavior of rivers. Preaching their new stewardship philosophy to anyone who might listen-their supervisors, duck hunters, conservationists, politicians, federal agencies-they were often ignored. The campaign dragged on for twenty years before an innovative and rational plan came from the Governor's Office and gained wide support. But then, too, that plan fell prey to politics, legal wrangling, self-interest, hardheadedness, and tradition. Yet, despite such heartbreaking setbacks, the author points to hopeful signs that West Tennessee's historic wetlands might yet be recovered for the benefit of all who use them and recognize their vital importance. Jim W. Johnson, now retired, was for many years a lands management biologist with the Tennessee Wildlife Resources Agency. He was responsible for the overall supervision and coordination of thirteen wildlife management areas and refuges, primarily for waterfowl, in northwest Tennessee.

The book is the first of its kind to deal with almost the entire swath of water resources assessment, development and sustainable management. The idea of the book crystallized during the long journey of the Editors on various facets of water issues in India and abroad during their extended association, at all levels with the Ministry of Water Resources, River Development and Ganga Rejuvenation, as well as International Organizations dealing with water. Currently water-stressed, India is likely to become water scarce in not too distant a future. The global freshwater supply and its sustainable use for human consumption, and conservation of the ecosystem have never come under such a rigorous scrutiny before. The unplanned and reckless exploitation of this precious resource have led to a crisis situation, compounded by a real threat of climate change. This book is, therefore, timely and of particular relevance not only to India but the entire world. The book contains 20 chapters, beside the lead article by the Editors. The chapters are contributed by the eminent professionals, researchers, academicians and civil society representatives having an in-depth understanding of the issues. The contents of the chapters have been chosen to represent all aspects of water. The assessment of water resources using satellite data and in-depth analyses of groundwater sector like, the Aquifer Mapping Programme initiated by Government of India, application of gravity satellite data to assess the resource build up, artificial recharge of aquifers and its contamination, are dealt with by eminent experts. The articles on sustainable management of water through good governance by community participation and involvement of civil society are placed. Flood management both through a basin level approach as well as by building resilience in vulnerable areas is discussed. Other critical issues like water bodies management, constitutional provisions, water governance and financial issues, hydro-power and need of research and development in this sector are also dealt with aptly. In view of emerging crisis and complexities in this sector the future pathways and the paradigm shift that is required in administrative and policy level is also discussed.

This book highlights the need for effective water governance in India given the fact that the country has been facing serious water stress in recent years. The water management in the country needs a serious scientific understanding coupled with the cooperative approach rather than a competitive one. It looks at current water regulations and underlines the need for overhaul of some laws to ensure that high water usage efficiency is attained, groundwater depletion is arrested and management of available resources is carried out in a disciplined manner. It also looks at the role of stakeholder engagement and pricing as a mechanism to manage demand in the wake of rapid population growth and industrialization.

This book presents a collection of chapters covering research on the Litani River Basin. The Litani River Basin occupies about a quarter of Lebanon's surface area, and it has recently been subject to severe geo-environmental conditions such as water contamination and decreased discharge. This motivated the Lebanese government to take action and start working on the remediation of the river. These actions are also supported by international organizations including the World Bank.

This book focuses on the spatial distribution of landslide hazards of the Darjeeling Himalayas. Knowledge driven methods and statistical techniques such as frequency ratio model (FRM), information value model (IVM), logistic regression model (LRM), index overlay model (IOM), certainty factor model (CFM), analytical hierarchy process (AHP), artificial neural network model (ANN), and fuzzy logic have been adopted to identify landslide susceptibility. In addition, a comparison between various statistical models were made using success rate cure (SRC) and it was found that artificial neural network model (ANN), certainty factor model (CFM) and frequency ratio based fuzzy logic approach are the most reliable statistical techniques in the assessment and prediction of landslide susceptibility in the Darjeeling Himalayas. The study identified very high, high, moderate, low and very low landslide susceptibility locations to take site-specific management options as well as to ensure developmental activities in theDarjeeling Himalayas. Particular attention is given to the assessment of various geomorphic, geotectonic and geohydrologic attributes that help to understand the role of different factors and corresponding classes in landslides, to apply different models, and to monitor and predict landslides. The use of various statistical and physical models to estimate landslide susceptibility is also discussed. The causes, mechanisms and types of landslides and their destructive character are elaborated in the book. Researchers interested in applying statistical tools for hazard zonation purposes will find the book appealing.

This book shows how the change of water paradigm has become urgent, and provides evidence for new policies that expand water balance to green and virtual water. The issue of water security concerns drinking water supply but also food safety, linked to agricultural policy. Both rain-fed and irrigated agriculture play complementary roles in food security, and the water issue implies a holistic view of water resources. This view constitutes the book's backstory. The reader will find original ideas that can be applied everywhere because the example of Tunisia is typically a basis to illustrate a universally prevalent situation. The book deals with other important issues: desalination, wastewater recycling, water quality, groundwater overdraft, water savings, governance, knowledge valuing, education, information: upgrading the whole water systems for the future implies emancipation of the whole society.

This book tries to answer the question how different communities in such an arid area as the Iranian central plateau could have shared their limited water resources in a perfect harmony and peace over the course of history. They invented some indigenous technologies as well as cooperative socio-economic systems in order to better adapt themselves to their harsh environment where the scarce water resources had to be rationed among the different communities as sustainably as possible. Those stories hold some lessons for us on how to adjust our needs to our geographical possibilities while living side by side with other people. This work gives insight into the indigenous adaptation strategies through the territorial water cooperation, and describes how water can appear as a ground for cooperation. It explains the water supply systems and social aspects of water in central Iran. Topics include the territorial water cooperation, qanat's, the traditional water management and sustainability, the socio-economic context, the sustainable management of shared aquifers system and more.
