The aim of this book is to document for the first time the dimensions and requirements of effective integrated groundwater management (IGM). Groundwater management is a formidable challenge, one that remains one of humanity’s foremost priorities. It has become a largely non-renewable resource that is overexploited in many parts of the world. In the 21st century, the issue moves from how to simply obtain the water we need to how we manage it sustainably for future generations, future economies, and future ecosystems. The focus then becomes one of understanding the drivers and current state of the groundwater resource, and restoring equilibrium to at-risk aquifers. Many interrelated dimensions, however, come to bear when trying to manage groundwater effectively. An integrated approach to groundwater necessarily involves many factors beyond the aquifer itself, such as surface water, water use, water quality, and ecohydrology. Moreover, the science by itself can only define the fundamental bounds of what is possible; effective IGM must also engage the wider community of stakeholders to develop and support policy and other socioeconomic tools needed to realize effective IGM. In order to demonstrate IGM, this book covers theory and principles, embracing: 1) an overview of the dimensions and requirements of groundwater management from an international perspective; 2) the scale of groundwater issues internationally and its links with other sectors, principally energy and climate change; 3) groundwater governance with regard to principles, instruments and institutions available for IGM; 4) biophysical constraints and the capacity and role of hydroecological and hydrogeological science including water quality concerns; and 5) necessary tools including models, data infrastructures, decision support systems and the management of uncertainty. Examples of effective, and failed, IGM are given. Throughout, the importance of the socioeconomic context that connects all effective IGM is emphasized. Taken as a whole, this work relates the many facets of effective IGM, from the catchment to global perspective.

Burgeoning population and climate change are among the most critical challenges facing the 21st century. Both have critical implications for groundwater resources, especially in many developing countries where resources are already under pressure. Due to low rainfall and high evaporation in parts of the Middle East and North Africa, groundwater is not being renewed, and groundwater laid down up to 10,000 years ago is literally being mined for irrigation, often very inefficiently. Over recent decades, groundwater levels have fallen dramatically in key grain-growing regions like the American Great Plains and the North China Plain. As the population grows and emerging economies like China and India demand more food, especially water intensive meat products, agricultural demand for water is set to increase. The rapid shift of population from the countryside to the cities is also adding to this pressure; most old wells in Beijing are now dry. Pollution from industry, agriculture and shanty towns is destroying many groundwater resources; some could take 50 years to clean up even with strict and immediate controls. This volume looks at the technical, socio-economic and political problems being faced, and at the developments in groundwater science and management that may help create a sustainable future for our planet.

The book presents an overview of recent advances in knowledge related to the assessment and management of groundwater resources, giving special attention to the uncertainties related to climate change and variability. While proposing strategies of groundwater management as adaptation, alternative and resilience under the changing environments, this book also discusses new directions and initiatives of hydrological study, in particular on the groundwater. Groundwater is a major source of water across much of the world, and acts as a component of the global water cycle on the Earth. Groundwater has the capacity to balance large swings in precipitation and has the potential to supplement surface-water resources when they are close to the limits of sustainability such as during drought. Although groundwater is pivotal to sustain water supplies, these important resources are vulnerable to increased human activities and the uncertain consequences of climate change. This book presents that groundwater with longer resident time of water circulation can be an alternative water resources and environment in changing climate. Assessments of groundwater services and benefit as well as risk are important for sustainable groundwater uses under the climate change. Groundwater which is one of the leys of adaptation to climate change should be treated as common resources and environment beyond the tragedy of the commons and dilemma of the boundaries. While providing a comprehensive description of hydrogeological characteristics of groundwater systems, the present volume also covers important aspects of legal and institutional contexts required for groundwater resources management as well as social and economic considerations. This publication may contribute to an improved understanding of the impacts of climate change and human activity on groundwater resources, provides useful guidance for policy makers and planners to include groundwater into climate change adaptation schemes and strategies.

Since human beings first appeared on the earth, we have changed land cover and land use for our own purposes, such as conveniences and high productivity. As a result of the land cover and land use changes, many serious environmental problems occur on the earth. Studying meteorological and hydrological effects of vegetation and land cover/use changes helps us to understand the environmental changes and problems happening near the earth surface, because the vegetation distributes the solar energy and water on the earth surface into atmosphere and geosphere. Subsurface hydrological responses to land cover and land use changes have drawn only regional environmental concerns, although global change caused by biosphere change has been studied in various scientific fields. The changes in land cover and land use alter water, solute and heat cycles in basins and elements of those balances, including evapotranspiration, groundwater recharge rate, discharge rates into rivers or ocean and soil moisture content, which are directly or indirectly related to the global environmental issues. Therefore, the changes in biosphere may substantially alter the subsurface hydrological system. For instance, increased groundwater recharge rates following clearing forest into grasses might be one consequence resulting in rising water tables and salinization.

It is important for the reader to understand clearly the objectives of these papers. They are not an attempt to provide accurate predictions of what is going to happen in Australia over the next few decades. Rather they represent sensitivity studies, designed to illustrate to what extent we as a nation are dependent on the climate and likely to be affected by climatic change, and attempts to develop the techniques for such sensitivity analyses. For this, the climate scenario (reproduced in the Appendix to this volume), was a key.

There is a general consensus that for the next few decades at least, the Earth will continue its warming. This will inevitably bring about serious environmental problems. For human society, the most severe will be those related to alterations of the hydrological cycle, which is already heavily influenced by human activities. Climate change will directly affect groundwater recharge, groundwater quality and the freshwater-seawater interface. The variations of groundwater storage inevitably entail a variety of geomorphological and engineering effects. In the areas where water resources are likely to diminish, groundwater will be one of the main solutions to prevent drought. In spite of its paramount importance, the issue of 'Climate Change and Groundwater' has been neglected. This volume presents some of the current understanding of the topic.

This volume arises from the work of the International Geographical Union Working Group on Regional Hydrological Response to Climate Change and Global Warming under the chairmanship of Professor Changming Liu (1992-96). The book consists mostly of peer-reviewed papers delivered at the Working Group's first three scientific meetings held in Washington, D.C. (1992), Lhasa, Tibet (1993) and Moscow (1995). These have been supplemented by a few additional chapters that have been specifically commissioned in order to give a well-rounded coverage of the global and scientific aspects of the topic. As editors, we have sought to balance state-of-the-art reviews of methodology and regional research with detailed studies of specific countries and river basins. In the spirit of the IGU, we have devoted particular effort to encouraging contributions from scientists in the non-English-speaking world. These chapters provide valuable evidence of recent climatic change and predictions of future hydrological impacts from parts of the world where little detailed work has been conducted hitherto. They provide much valuable information that is new and interesting to an international audience and is otherwise very difficult or impossible to acquire. It is hoped that the present volume will be not only a record of current achievements, but also a stimulus to further hydrological research as the detail and spatial resolution of Global Climate Models improves. One notable aspect that emerges from a number of the contributions is that many, though by no means all, recent hydrological trends are in line with global warming predictions.
