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.

Water Conservation in the Era of Global Climate Change reviews key issues surrounding climate change and water resources. The book brings together experts from a variety of fields and perspectives, providing a comprehensive view on how climate change impacts water resources, how water pollution impacts climate change, and how to assess potential hazards and success stories on managing and addressing current issues in the field. Topics also include assessing policy impacts, innovative water reuse strategies, and information on impacts on fisheries and agriculture including food scarcity. This book is an excellent tool for researchers and professionals in Climate Change, Climate Services and Water Resources, and those trying to combat the impacts and issues related to Global and Planetary Change. - Covers a wide range of theoretical and practical issues related to how climate change impacts water resources and adaptation, with extended influence on agriculture, food and water security, policymaking, etc. - Reviews mathematical tools and simulations models on predicting potential hazards from climate change in such a way they can be useful to readers from a variety of levels of mathematical expertise - Examines the potential impacts on agriculture and drinking water quality - Includes case studies of successful management of water and pollutants that contribute to climate change

In recent years, a greater level of integration of the world economy and an opening of national markets to trade has impacted virtually all areas of society. The process of globalization has the potential to generate long-term benefits for developing countries, including enhanced technology and knowledge transfers and new fina- ing options supporting agricultural and economic development. However, risks of political and economic instability, increased inequality, and losses in agricultural income and production for countries that subsidize their agricultural and other e- nomic sectors threaten to offset potential benefits. Globalization can also have a profound impact on the water sector – in terms of allocation and use of water – and thus on food security as well. Other global change processes, particularly climate change, are also likely to have far-reaching impacts on water and food security, and societies around the world. To discuss these issues in-depth, the International Food Policy Research Institute, the Third World Centre for Water Management, Mexico, and the Tropical Agricultural Research and Higher Education Center (CATIE), Costa Rica, held a three-day International Conference on “Globalization and Trade: Implications for Water and Food Security,” at CATIE’s Turrialba, Costa Rica, headquarters under the auspices of the CGIAR Challenge Program on Water and Food in 2005. The workshop set out to identify the major risks and emerging issues facing developing countries related to global economic and environmental change impacts on water and food 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.

This book highlights the relationship between the water sector and various other sectors in order to establish an improved understanding of the importance of water resources as an essential cross-cutting vector of socio-economic development. The book is both policy and practice oriented and is not constrained by existing definitions on water security. It includes actual experiences of policy, management, development and governance decisions taken within the water sector, and examples on how these have affected the energy and agricultural sectors as well as impacted the environment, and vice versa, as appropriate. It also discusses trade-offs, short and long-term implications, lessons learnt, and the way forward. The book includes case studies on cities, countries and regions such as Australia, China, Singapore, Central Asia, Morocco, Southern Africa, France, Latin America, Brazil and California.
