Always considered a classic renewable resource, after a hundred thousand years of farming and industry, rivers in many parts of the world are running dry and the groundwater is over pumped. In addition, the rate at which water sources are becoming contaminated with waste from humans, industry, and agriculture is truly alarming. Do these factors add up to a water crisis that merits drastic, large-scale action?Not necessarily say the editors of Water Crisis: Myth or Reality. They challenge this pessimism, concluding that while there are serious global water issues to be considered, the concept of a global water crisis is largely overstated. The book examines the issues and explores which conditions are permanent and unchangeable and which are remediable and changeable. The chapters explore when and where severe regional and local water problems occur and make suggestions about how they may be solved in a deliberate, non-crisis manner. The book covers recent breakthroughs in desalination technologies, the eco-sanitation revolution, international trade in agricultural products, methods of governance and negotiation in water allocation, and pricing and devolution of property rights and the roles they play in solving water issues. The editors, along with a panel of world-renowned experts, suggest that water issues can be solved over the next few decades using new technologies and processes.

Intensive use of groundwater has resolved the demand for drinking water and, through irrigation, has contributed to the eradication of malnourishment in many developing countries. The spectacular worldwide increase in groundwater use in the last decades, especially in arid and semi-arid regions, has been a silent revolution carried out by millions of small farmers. In some instances, groundwater abstraction has caused problems of quality degradation, excessive drawdown of groundwater levels, land subsidence, reduction of spring and baseflows or degradation of groundwater-dependent ecosystems. Most of these problems could be anticipated, mitigated, or even avoided with more active water agencies, adequate regulations and users’ participation in management. Groundwater Intensive Use contains a selection of papers presented at a symposium held in December 2002 in Valencia, Spain. It constitutes a step forward in creating a greater worldwide awareness of the relevance of groundwater in water resources policy. The book presents new ideas and accounts of recent advances in technical, economic, legal, administrative and political issues. It addresses groundwater development to ecosystems sustainability, through different or complementary approaches. A wide series of case studies from North and South America, Europe, South Asia and North and Sub-Saharan Africa cover the various issues. These case studies represent countries with a wide diversity of social circumstances, from areas in which development is emerging, to communities with a long history of successful groundwater use.

This book provides an overview, by leading world experts, on key issues in global water and food security. The book is divided in a series of over-arching themes and sections. The first part of the book provides an overview of water and food security. The second and third sections look at global trade and virtual water trade, and provide some specific examples on the application of the water footprint at different scales. The fourth section sets the context into wider debates related to global sustainable production and consumption. The last section of the book addresses the role of the silent groundwater revolution to help address water and food security; the water/energy nexus, and the potential for generating ´new´ water.
