In 2014, China initiated its national action plan for sponge city development aiming to tackle urban water and environmental challenges. Since then, numerous projects have been implemented across 30 pilot cities and beyond in China through two development stages. The sponge city development, based on a systematic approach of “source reduction, process control, and systematic remediation”, adopts comprehensive technical measures of “infiltration, detention, retention, purification, utilization and discharge”, and coordinates the different aspects of water quantity and quality, ecology and safety, centralized and decentralized, green and grey, landscape and function, on-shore and off-shore, surface and underground, etc. It aims to control urban runoff effectively, to minimize the impacts of urban development and construction activities on the natural hydrological characteristics and ecological environment, and to enable the city’s resilience like a “sponge” to adapt to environmental changes and natural disasters. This assessment standard for sponge city effects published by the Ministry of Housing and Urban-Rural Development of P.R. China is an attempt to provide guidance on the assessment of the effects of sponge city development projects and the city development as a whole. The main technical contents of this standard include: 1) general provisions; 2) terms and symbols; 3) basic requirements; 4) assessment items and 5) assessment methods. The publication of the English version of the Chinese assessment standard aims to provide non-Chinese readers an insight into what objectives are to be achieved through sponge city development and how sponge city projects are evaluated in China.

Building water-wise cities is a pressing need nowadays in both developed and developing countries. This is mainly due to the limitation of the available water resources and aging infrastructure to meet the needs of adapting to social and environmental changes and for urban liveability. This is the first book to provide comprehensive insights into theoretical, systematic, and engineering aspects of water-wise cities with a broad coverage of global issues. The book aims to (1) provide a theoretical framework of water-wise cities and associated sustainable water systems including key concepts and principles, (2) provide a brand-new thinking on the design and management of sustainable urban water systems of various scales towards a paradigm shift under the resource and environmental constraints, and (3) provide a technological perspective with successful case studies of technology selection, integration, and optimization on the “fit-for-purpose” basis.

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.

#1 NEW YORK TIMES BEST SELLER • In this urgent, authoritative book, Bill Gates sets out a wide-ranging, practical—and accessible—plan for how the world can get to zero greenhouse gas emissions in time to avoid a climate catastrophe. Bill Gates has spent a decade investigating the causes and effects of climate change. With the help of experts in the fields of physics, chemistry, biology, engineering, political science, and finance, he has focused on what must be done in order to stop the planet's slide to certain environmental disaster. In this book, he not only explains why we need to work toward net-zero emissions of greenhouse gases, but also details what we need to do to achieve this profoundly important goal. He gives us a clear-eyed description of the challenges we face. Drawing on his understanding of innovation and what it takes to get new ideas into the market, he describes the areas in which technology is already helping to reduce emissions, where and how the current technology can be made to function more effectively, where breakthrough technologies are needed, and who is working on these essential innovations. Finally, he lays out a concrete, practical plan for achieving the goal of zero emissions—suggesting not only policies that governments should adopt, but what we as individuals can do to keep our government, our employers, and ourselves accountable in this crucial enterprise. As Bill Gates makes clear, achieving zero emissions will not be simple or easy to do, but if we follow the plan he sets out here, it is a goal firmly within our reach.

The uptake of ecosystem-based approaches for disaster risk reduction (DRR) is slow, however, despite some success stories. There are multiple reasons for this reluctance: ecosystem management is rarely considered as part of the portfolio of DRR solutions because the environmental and disaster management communities typically work independently from each other; its contribution to DRR is highly undervalued compared to engineered solutions and therefore not given appropriate budget allocations; and there are poor interactions between policymakers and researchers, leading to unclear and sometimes contradictory scientific information on the role of ecosystems for DRR. The aim of this book is to provide an overview of knowledge and practice in this multidisciplinary field of ecosystems management and DRR. The contributors, professionals from the science and disaster management communities around the world, represent state-of-the-art knowledge, practices, and perspectives on the topic.
