With the increasing threat of depleted and contaminated water supplies around the world, this book provides a timely and much needed analysis of how cities should manage this precious resource. Integrating the environmental, economic, political and socio-cultural dimensions of water management, the authors outline how future mega-city systems can maintain a high quality of life for its residents.
"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.
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.
Sustainable Mega City Communities scrutinizes the challenges encountered when designing, planning and constructing sustainable megacities. Chapters explain the role of national and local governments for the strategic planning, development, implementation, monitoring and enforcement of standards of water, air, food and products used by the community. Other chapters cover Water Delivery Systems, Sanitation and Waste Disposal Systems, Power Systems, and Public Health Systems, new green technologies, practices, and standards predicated by the need for sustainable office building and housing. Provides an in-depth look at critical infrastructural systems, charting problems and providing possible solutions Addresses new green technologies, practices and standards predicated by the need for sustainable office building and housing Explains the role of national and local governments for strategic planning, development, implementation, monitoring and enforcement
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.
This book provides a unique synthesis of concepts and tools to examine natural resource, socio-economic, legal, policy and institutional issues that are important for managing urban growth into the future. The book will particularly help the reader to understand the current issues and challenges and develop strategies and practices to cope with future pressures of urbanisation and peri-urban land, water and energy use challenges. In particular, the book will help the reader to discover underlying principles for the planning of future cities and peri-urban regions in relation to: (i) Balanced urban development policies and institutions for future cities; (ii) Understanding the effects of land use change, population increase, and water demand on the liveability of cities; (iii) Long-term planning needs and transdisciplinary approaches to ensure the secured future for generations ahead; and (iv) Strategies to adapt the cities and land, water and energy uses for viable and liveable cities. There are growing concerns about water, food security and sustainability with increased urbanisation worldwide. For cities to be liveable and sustainable into the future there is a need to maintain the natural resource base and the ecosystem services in the peri-urban areas surrounding cities. This need is increasing under the looming spectre of global warming and climate change. This book will be of interest to policy makers, urban planners, researchers, post-graduate students in urban planning, environmental and water resources management, and managers in municipal councils.
This book features expert contributions on key sustainability aspects of urban water management in Chinese agglomerations. Both technical and institutional pathways to sustainable urban water management are developed on the basis of a broad, interdisciplinary problem analysis.
This paper highlights key urban groundwater issues and management needs. It also raises awareness and understanding of hydrogeological processes in urban areas and provides a framework for the proper and systematic consideration of groundwater dimensions in urban management. This paper suggests options for greater sustainable development and management of groundwater in urban areas.
