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.

Groundwater is invisible, but its impact is visible everywhere. Everything around us relies on groundwater, our drinking water and sanitation, our food supply and our natural environment. Yet because it is invisible, information, management and governance of groundwater is often poor and inadequate. This book contributes to UN Water Groundwater year (2022), and to the effort of “making the invisible, visible”. Through worldwide case studies ranging from the Americas (California, Brazil), to Asia (India, Iran, Lao PDR, Nepal), Africa (Malawi, Tanzania, South Africa) and the MENA region (Lebanon, Morocco, Yemen), including cases of transboundary aquifers, the chapters in this edited volume reflect important recent advances in interdisciplinary knowledge on the governance, management, practice and science-policy interfaces of groundwater. An insightful resource for researchers and planners in the field of environmental policies, water laws, climate change and groundwater governance, this book comes with a new Introduction. The other chapters were originally published in Water International.

Groundwater contributes to the sustainable development of many Asian cities by providing water for domestic, industrial and agricultural uses and regulating ecosystem flows. However, groundwater has not always been properly managed, which often has resulted in depletion and degradation of the resource. Groundwater Environment in Asian Cities presents the up-to-date scientific knowledge on groundwater environment in fourteen Asian cities using Driver-Pressure-State-Impact-Response (DPSIR) framework. In detail the book presents the facts and figures of groundwater dependency, problems related to groundwater over exploitation, implementation of various policy instruments and management practices and their results in selected fourteen Asian cities, namely; Bandung (Indonesia), Bangkok (Thailand), Beijing (China), Bishkek (Kyrgyzstan), Chitwan (Nepal), Delhi (India), Dili (East Timor), Ho Chi Minh (Vietnam), Hyderabad (India), Khulna (Bangladesh), Lahore (Pakistan), Seoul (South Korea), Tokyo (Japan), and Yangon (Myanmar). The book provides the one-step platform to get sufficient details about groundwater aquifers, hydrogeology, groundwater status, impacts on groundwater environment and responses (technology, policy, institutional, etc.) deployed in the case studies cities, and therefore, provides a snap-shot of Asian groundwater environments. The theoretical background of the topics discussed along with the case studies help the readers understand the similarities and differences about the status of groundwater development and use in each city. In addition, the information in the book will serve as a baseline for other research such as mitigation of groundwater related problems (e.g., land subsidence), impact of climate change on groundwater, and importance of groundwater for implementing sustainable development goals in future. - Presents a framework for evaluating groundwater environment in urban environments - Includes case studies and local examples from a broad geographical range of urban environments from virtually every region in Asia, including Bandung, Bangkok, Delhi, Bishkek, Beijing and Tokyo - The book will be a valuable resource for groundwater adversaries in the scientific, decision-making and end-user communities, particularly for understanding and assessing state of groundwater resources in the region as well as learning from the responses practiced so far (Dr. Linda Anne Stevenson, APN) - The contents in this book are very much useful for informed decision-making for protecting groundwater environemntand therefore contributes in making invisible visible (Dr. Neno Kukuric, IGRAC) - With concrete examples and lessons for readers, this book responds to the call for comprehensive research and studies, the implementation of new science-based methodologies and endorsement of principles for groundwater resources management and cities (Dr. Aureli Alice, UNESCO-IHP) - As a "Regional Hub for Groundwater Management in the Asia Pacific Region, IGES finds this book as a very much useful reference for knowledge hub partners, groundwater managers, academic institutions, research scholars, and international organizations working in the areas of groundwater in Asia and beyond (Dr. Hideyuki Mori, IGES)

Groundwater has provided great benefits to agriculture irrigation in semi-arid OECD countries, but its intensive use beyond recharge in certain regions has depleted resources and generated significant negative environmental externalities.

Groundwater resources are facing increasing pressure from consuming and contaminating activities. There is a growing awareness that the quantitative and qualitative preservation of groundwater resources is a global need, not only to safeguard their future use for public supply and irrigation, but also to protect those ecosystems that depend partial

This Special Issue presents the work of 30 scientists from 11 countries. It confirms that the impacts of global change, resulting from both climate change and increasing anthropogenic pressure, are huge on worldwide coastal areas (and critically so on some islands in the Pacific Ocean), with highly negative effects on coastal groundwater resources, which are widely affected by seawater intrusion. Some improved research methods are proposed in the contributions: using innovative hydrogeological, geophysical, and geochemical monitoring; assessing impacts of the changing environment on the coastal groundwater resources in terms of quantity and quality; and using modelling, especially to improve management approaches. The scientific research needed to face these challenges must continue to be deployed by different approaches based on the monitoring, modelling and management of groundwater resources. Novel and more efficient methods must be developed to keep up with the accelerating pace of global change.

A complete treatment of the theory and practice of groundwater engineering, The Handbook of Groundwater Engineering, Second Edition provides a current and detailed review of how to model the flow of water and the transport of contaminants both in the unsaturated and saturated zones, covers the production of groundwater and the remediation of contaminated groundwater.

Groundwater Contamination in Coastal Aquifers: Assessment and Management first describes groundwater contamination in coastal aquifers and then delves into specific topics surrounding various hydrogeochemical processes. Next, the book covers case studies of groundwater quality assessment using recent techniques, explains the various pollutants and contaminants in coastal aquifers, and covers management and remediation methods to control contamination in coastal aquifers. This key reference encompasses various topics in broader perspectives on groundwater contamination in coastal aquifers, providing a significant contribution to the field of hydrogeology. - Presents global case studies that show the reader how this issue is affecting sites around the world - Includes a remediation plan that solves problems surrounding the management of groundwater, water treatment techniques, and the management of available groundwater resources - Provides advanced techniques that can be applied and used as methodologies for solving groundwater issues

The over-exploitation of groundwater and marked changes in climate over recent decades has led to unacceptable declines in groundwater resources. Under the likely scarcity of available water resources in the near future, it is critical to quantify and manage the available water resources. With increasing demand for potable water for human consumption, agriculture, and industrial uses, the need to evaluate the groundwater development, management, and productivity of aquifers also increases. Laboratory Manual for Groundwater, Wells, and Pumps serves as a valuable resource and provides a multi-disciplinary overview for academics, administrators, scientists, policymakers, and professionals involved in managing sustainable groundwater development programs. It includes practical guidance on the measurement of groundwater flow, soil properties, aquifer properties, wells and their design, as well as the latest state-of-the-art information on pumps and their testing, and groundwater modeling. Features: Covers basics of groundwater engineering, advanced methodologies, and their applications and groundwater modeling Examines groundwater exploration, planning and designing, and methods for formulating strategies for sustainable management and development Serves as a reference for practitioners on practical applications and frequently occurring issues of groundwater investigations, development, and management.
