This book highlights the likely impacts of climate change in terms of global and national water securities, how different countries are attempting to address these complex problems and to what extent they are likely to succeed. A major global concern at present, especially after the social and economic havoc that has been caused by COVID-19 in only one year, is how we can return to earlier levels of economic development patterns and then further improve the process so that sustainable development goals are reached to the extent possible by 2030, in both developed and developing countries. Mankind is now facing two existential problems over the next several decades. These are climate change and whether the world will have access to enough water to meet all its food, energy, environment and health needs. Much of expected climate change impacts can be seen through the lens of extreme hydrological events, like droughts, floods and other extreme hydrometeorological events.

This book presents selected papers from the 7th International Conference on Water and Flood Management,with a special focus on Water Security under Climate Change, held in Dhaka, Bangladesh in March 2019. The biennial conference is organized by Institute of Water and Flood Management of Bangladesh University of Engineering and Technology. The recent decades have experienced more frequent natural calamities and it is believed that climate change is an important driving factor for such hazards. Each part of the hydrological cycle is affected by global climate change. Moreover, increasing population and economic activities are posing a bigger threat to water sources. To ensure sustainable livelihoods, safeguard ecosystem services, and enhance socio-economic development, water security needs to be investigated widely in a global and regional context.

This book pursues a comprehensive approach so as to arrive at a better understanding of the implications of climate change on sustainable development, focusing on the perspective of water. Climate change is one of today’s most pressing global issues and will become increasingly important in the decades to come, as societies will feel its pervasive impacts in many aspects of their lives. Given that the majority of these climate change impacts will be felt through the medium of water, the book explores the interrelationships and inter-linkages between water, climate change and sustainable development.

This volume collects essays from academics and practitioners from a diversity of areas and perspectives in order to discuss water security at various levels and to illuminate the central idea of water security: its focus on the individual. Beginning with the big picture, this book aims to illustrate the depth of the water security crisis and its interconnections with other aspects of societal development. It particularly draws a connection to the 2030 Agenda for Sustainable Development, and discusses that challenges faced in meeting the 17 sustainability development goals (SDG) by the year 2030. Moving from international to domestic and community perspectives, this book provides a unique analysis of issues and solutions to the water issues we face today in light of the ever looming global changes brought on by climate change. Over the past few decades the recognition of our common need for water has increased, as policymakers have sought to place more focus on the individual within policy. After the recognition of water and sanitation as a fundamental human right by the United Nations General Assembly in 2010, there is increasing recognition of the individual as the building block for the struggle for water security. This reality also intersects with adverse impacts of global climate change, and the book responds to the broader question: will clean and safe water be available where we need it and when we need it in the future?

FUNDAMENTALS OF WATER SECURITY Understand How to Manage Water Resources to Equitably Meet Both Human and Ecological Needs Burgeoning populations and the ever-higher standards of living for those in emerging countries increase the demand on our water resources. What is not increasing, however, is the supply of water and the total amount of water in earth’s biosphere—water that is integral to all standards of living. Fundamentals of Water Security provides a foundation for understanding and managing the quantity-quality-equity nexus of water security in a changing climate. In a broad sense, this volume explores solutions to water security challenges around the world. It is richly illustrated and pedagogically packed with up-to-date information. The text contains chapter learning objectives, foundation sections reviewing quantitative skills, case studies, and vignettes of people who have made important contributions to water security. To further aid comprehension, end-of-chapter problems are included—both qualitative and quantitative, with solutions available to instructors. Finally, extensive references feature books, journal articles, and government and NGO reports. Sample topics discussed include: How the study of water resources has evolved from a focus on physical availability to include social factors and governance How water security affects multiple disciplines across environmental science and engineering, hydrology, geography, water resources, atmospheric science, chemistry, biology, health science, and social and political science fields How to achieve a sufficient quantity and quality of water to equitably meet both immediate and long-term human and ecological needs Analysis of water security in an integrated manner by underscoring the complex interactions between water quantity, water quality, and society Students taking courses on hydrology, water security, and/or water resource management, along with scientists working in fields where water security is a factor will be able to use Fundamentals of Water Security as a comprehensive textbook to understand and achieve water security.

The world is on the brink of the greatest crisis it has ever faced: a spiraling lack of fresh water. Groundwater is drying up, even as water demands for food production, for energy, and for manufacturing are surging. Water is already emerging as a headline geopolitical issue—and worsening water security will soon have dire consequences in many parts of the global economic system. Directed by UN Secretary General Ban Ki-Moon at the 2008 Davos Annual Meeting, the World Economic Forum assembled the world’s foremost group of public, private, non-governmental-organization and academic experts to examine the water crisis issue from all perspectives. The result of their work is this forecast—a stark, non-technical overview of where we will be by 2025 if we take a business-as-usual approach to (mis)managing our water resources. The findings are shocking. Perhaps equally stunning are the potential solutions and the recommendations that the group presents. All are included in this landmark publication. Water Security contains compelling commentary from leading decision-makers, past and present. The commentary is supported by analysis from leading academics of how the world economy will be affected if world leaders cannot agree on solutions. The book suggests how business and politics need to manage the energy-food-water-climate axis as leaders negotiate the details of the climate regime that replace Kyoto Protocols.

The purpose of this book is to present an overview of the latest research, policy, practitioner, academic and international thinking on water security—an issue that, like water governance a few years ago, has developed much policy awareness and momentum with a wide range of stakeholders. As a concept it is open to multiple interpretations, and the authors here set out the various approaches to the topic from different perspectives. Key themes addressed include: Water security as a foreign policy issue The interconnected variables of water, food, and human security Dimensions other than military and international relations concerns around water security Water security theory and methods, tools and audits. The book is loosely based on a masters level degree plus a short professional course on water security both given at the University of East Anglia, delivered by international authorities on their subjects. It should serve as an introductory textbook as well as be of value to professionals, NGOs, and policy-makers.
