"This book is the outcome of the International Conference 'Water, Megacities and Global Change', and represents the collective work of 33 authors and co-authors. It contains summaries of monographs on 15 emblematic megacities: Beijing, Buenos Aires, Chicago, Ho Chi Minh City, Istanbul, Lagos, London, Los Angeles, Manila Mexico, Mumbai, New York, Paris, Seoul and Tokyo. This edition provides unique information about water management in these megacities."--Final page of pdf.
As urbanization continues, and even accelerates, scientists estimate that by 2015 the world will have up to 60 ‘megacities’ – urban areas with more than five million inhabitants. With the irresistible economic attractions of urban centers, particularly in developing countries, making the influx of citizens unstoppable, many of humankind’s coming social, economic and political dramas will be played out in megacities. This book shows how geographers and Earth scientists are contributing to a better understanding of megacities. The contributors analyze the impact of socio-economic and political activities on environmental change and vice versa, and identify solutions to the worst problems. They propose ways of improving the management of megacities and achieving a greater degree of sustainability in their development. The goals, of wise use of human and natural resources, risk reduction (both social and environmental) and quality of life enhancement, are agreed upon. But, as this text proves, the means of achieving these ends are varied. Hence, chapters cover an array of topics, from health management in Indian megacities, to planning in New York, to transport solutions for the chronically traffic-choked Bangkok. Authors cover the impact of climate change on megacities, as well as less tangible issues such as socio-political fragmentation in the urban areas of Rio de Janeiro. This exploration of some of the most crucial issues that we face as a species sets out research that is of the utmost importance, with the potential to contribute substantially to global justice and peace – and thereby prosperity.

Urban Water Crisis and Management: Strategies for Sustainable Development, Sixth Edition presents solutions for the current challenges of urban water and management strategies. Through contributed chapters, a framework is laid out for a reduction of the use of groundwater (heavily overused as a solution) and the alternative options for the supply of water to cities, or for urban water. Sections discuss urban water, its problems and management approaches, address the root causes of the water crisis in urban areas, and cover the scientific and technical knowledge necessary to manage water resources. Significant gaps between developed and developing nations in the procedure of water management are also addressed, along with practical information regarding recycling and the reuse of wastewater which is useful as baseline data for the future. Presents the quantitative study of water supply in urban areas, identifies water scarcity in megacities, and provides management approaches for sustainable development Identifies technology and the instruments required for the management and safe supply of water Includes case studies where these technologies have been successfully used
This book highlights what are likely to be the future megatrends in the water sector and why and how they should be incorporated to improve water governance in the coming decades. In this first ever book on megatrends for the water sector, 22 leading world experts from different disciplines representing academia, business, government, national and international organisations discuss what the major megatrends of the future are and how they will radically change water governance in the coming decades.

The 2020 edition of the WWDR, titled Water and Climate Change illustrates the critical linkages between water and climate change in the context of the broader sustainable development agenda. Supported by examples from across the world, it describes both the challenges and opportunities created by climate change, and provides potential responses – in terms of adaptation, mitigation and improved resilience – that can be undertaken by enhancing water resources management, attenuating water-related risks, and improving access to water supply and sanitation services for all in a sustainable manner. It addresses the interrelations between water, people, environment and economics in a changing climate, demonstrating how climate change can be a positive catalyst for improved water management, governance and financing to achieve a sustainable and prosperous world for all. The report provides a fact-based, water-focused contribution to the knowledge base on climate change. It is complementary to existing scientific assessments and designed to support international political frameworks, with the goals of helping the water community tackle the challenges of climate change, and informing the climate change community about the opportunities that improved water management offers in terms of adaptation and mitigation.
This book presents water insecurity issues in urban areas while developing a water security index and explores the innovative approaches to water development and management with examples from Asian cities. The urban water crisis is a global phenomenon, but it is more obvious in the megacities of the developing world. Urban drought, although not a familiar term, will pose a significant threat to humankind in the near future, especially in the context of increasing population in cities. Many cities are already unable to provide safe, clean water for their citizens. Some of the world’s largest cities depend heavily on groundwater for their water supply. It is unlikely that dependence on aquifers, which take many years to recharge, will be sustainable. As urban populations grow, water use will need to shift from agriculture to municipal and industrial uses, making decisions about allocating between different sectors difficult. Inefficient water-use practices by households and industries, fragmented management of water between sectors and institutions, climate-induced water shortages, environmental degradation of water sources, and inadequate use of alternate sources are also issues of major concern. Despite recent advances in the literature, there exists a considerable gap in attempting an integrated water-resource management approach. Covering all aspects of urban drought and water insecurity, this book is a valuable resource for students, researchers, academics, policy makers, and development practitioners.
Efficient and equitable water, wastewater and stormwater management for the megacities is becoming an increasingly complex task. The special issue will focus on water management in its totality for megacities, including their technical, social, economic, legal, institutional and environmental dimensions through a series of specially invited case studies from different megacities of the world. At present, around one out of two of the earth’s 6.3 billion people live in urban areas. Each year, the world population grows by around 80 millions. Practically all of this growth is urban, primarily due to migration. World’s urban population is expected to reach 5 billion by 2030, which is nearly 2/3rd more than in 2000, and would mean that 60% of world’s population will live in urban areas. The case studies analysed include some of the most interesting and challenging megacities of this planet, Dhaka, Istanbul, Jakarta, Johannesburg, México City, Riyadh and São Paulo. They assess different aspects of how water is intermingled in the overall development milleau. The special issue will considers the magnitudes, nature and extent of the present and future challenges and how these could be meet in socially acceptable and cost-effective ways. The contributors are all acknowledged water experts from different parts of the world. This book was previously published as a special issue of the International Journal of Water Resource s Development.
