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.

This book presents recent findings from the South Asian region (SA), broadly including groundwater studies on (a) quantity, (b) exploration, (c) quality and pollution, (d) economics, management and policies, (e) groundwater and society, and (f) sustainable sources. It offers a compilation of compelling, authentic insights into groundwater scenarios throughout the water-stressed South Asia region. Comprising Afghanistan, Bangladesh, Bhutan, India, Myanmar, Nepal, Pakistan, and Sri Lanka, it is the most densely populated region in the world: It occupies approximately 4% of the global land area but supports more than 25% of the global population. The SA region now faces an acute shortage of fresh water due to a rapid rise in water demand and changes in societal water-use patterns. Combining essential advances and perspectives, this book offers a valuable resource for all scientists, planners and policymakers who are interested in understanding and developing the SA and other related areas.

This book focuses on the transformation of Bangladesh in respect to its people, geography, economy and environment. The authors discuss current problems such as vulnerability caused by environmental degradation in Bangladesh but also opportunities of this rapidly changing country. The book explains how the country is rapidly transforming from a rural subsistence agrarian based economic system to a new economic partner contributing to global processes. Bangladesh is presented as an example for the changes in the Global South, where a mismatch is often observed in linking resources and activities with environmental sustainability, possibly due to insufficient base-line knowledge. As faster growth is marginalizing resources to increase the GDP, the sustainability of resource exploitation is being questioned. The authors describe the vulnerable situation caused by possible sea-level rise, soil degradation, biodiversity loss, climate extremities, urbanization, and population displacement. This volume offers comprehensive knowledge about the geography and environment of Bangladesh and aims to help readers further investigate the issues and work on solutions. The book appeals to academics, professionals and students at all levels interested in Bangladesh as well as environmental problems and geographical issues in a rapidly transforming country.

"Water is becoming an increasingly scarce resource for most of the world's citizens. The current trends indicate that the overall situation is likely to deteriorate further, at least for the next decade, unless the water profession eschews "business as usual" practices, which can only allow incremental changes to occur." Groundwater is the least understood and least appreciated, yet the most important, natural resource available to mankind. Groundwater represents about 97% of the existing fresh water resources, excluding the resources locked in polar ice. More than one and a half billion people in the urban parts of the world today depend on groundwater. Groundwater supply is more reliable than the seasonal, and sometimes erratic, surface water and provides the main line of defense against drought. Moreover, the quality of groundwater is, by and large, superior to surface water and cheaper to develop. However, when available, data on groundwater is very scanty. As a result, the World Bank is now paying increasing attention to this valuable resource, through both operations and sector work. This publication represents the proceeding of the seminar "Groundwater: Legal and Policy Perspectives" that was organized by the Legal Vice Presidency of the World Bank. It explains some basic technical aspects of groundwater, surveys the regulatory framework for it, and discusses the World Bank experience and international law regarding this precious resource. It is a timely publication and should also assist in a better understanding and appreciation of this valuable source. It will be of interest to Bank staff, borrowing country officials, international agencies and research organizations working on groundwater.

Ground water resources are receiving global attention, as human population growth and development cause significant changes to the earth system. It plays a major role in ensuring livelihood security in many parts of South Asia and its contribution to poverty alleviation is substantial. The complex nature of ground water problems in the Indian Sub-continent requires a precise delineation of the ground water regimes in different hydro geological settings and socio-economic conditions and is a primary necessity for sustainable and equitable management. Strategies to respond to ground water over-exploitation and deteriorating water quality must be based on a new approach. Practical policies and various solution options urgently need to be formulated and implemented to prevent the development problems. There is pressing need to evolve workable methods and approaches based on modern scientific researches on ground water resources, as well as to build a social framework including community participation at all levels for a ground water development system. The community participation in water pumping policies, incentives of efficient use, affordability of low income users and other vulnerable groups, water awareness are prime factors for success of any ground water based water supply project.

The Ganges Basin is a part of the Ganges-Brahmaputra-Meghna (GBM) River Basin and is one of the most populated (600 million) river basins in the world. This study focuses on the Eastern Ganges Basin (EGB) and covers India (Bihar, Jharkhand and West Bengal), Bangladesh and the Nepal Terai. Poverty is acute in the EGB, where household incomes are low, food security is not assured and devastating floods (and also water shortages) occur too often. The EGB is underlain by one of the most prolific aquifers in the world. Yet, farmers struggle to cope with dry spells and droughts because of their inability to access groundwater. Huge untapped groundwater, surplus surface water, and enormous plains and fertile lands highlight the requirement of proper planning for groundwater management and governance to reduce poverty and assure food security. The aim of this report is to assist planners/policymakers in the planning and management of groundwater resources in the EGB. This report mainly discusses about hydrogeology, groundwater potential and challenges, and groundwater quality issues in the EGB. Moreover, it is an attempt to form a base for future work related to groundwater development, management and modeling in this basin.
