“…The first turning point in China was in 2002, when a societal water-saving construction policy was set by central government [46]. There was further progress between 2003 and 2007, as megacities including Beijing began to better manage stormwater by improving their urban drainage systems and water pollution treatment works [47].…”

Urban flooding has become a serious issue in most Chinese cities due to rapid urbanization and extreme weather, as evidenced by severe events in Beijing (2012), Ningbo (2013), Guangzhou (2015), Wuhan (2016), Shenzhen (2019), and Chongqing (2020). The Chinese “Sponge City Program” (SCP), initiated in 2013 and adopted by 30 pilot cities, is developing solutions to manage urban flood risk, purify stormwater, and provide water storage opportunities for future usage. Emerging challenges to the continued implementation of Sponge Cities include (1) uncertainty regarding future hydrological conditions related to climate change projections, which complicates urban planning and designing infrastructure that will be fit for purpose over its intended operating life, and (2) the competing priorities of stakeholders and their reluctance to make trade-offs, which obstruct future investment in the SCP. Nature-Based Solutions (NBS) is an umbrella concept that emerged from Europe, which encourages the holistic idea of considering wider options that combine “Blue–Green” practices with traditional engineering to deliver “integrated systems of Blue–Green–Grey infrastructure”. NBS includes interventions making use of natural processes and ecosystem services for functional purposes, and this could help to improve current pilot SCP practices. This manuscript reviews the development of the SCP, focusing on its construction and design aspects, and discusses how approaches using NBS could be included in the SCP to tackle not only urban water challenges but also a wide range of social and environmental challenges, including human health, pollution (via nutrients, metals, sediments, plastics, etc.), flood risk, and biodiversity.

“…In addition, in order to ease the increasingly prominent water crisis, Tianjin put the most stringent water management system into practice, which has achieved remarkable results by setting out water use efficiency targets. In 2013, water use per unit of GDP was reduced to 17.52 m 3 , less than one-sixth of the national average, and water use per unit of industrial added value was reduced to 8.3 m 3 , representing the highest industrial water efficiency in China [34].…”

Urban water resources are the basis for the formation and development of cities and the source of urban water supply. However, with the acceleration of urbanization and the explosion of urban populations, the contradiction between water supply and demand in some areas, especially in big cities, has become increasingly prominent. It is simply not sufficient to rely on local conventional water resources to meet urban water demand, and a single source water supply mode has a higher vulnerability, resulting in greater safety risks in urban or regional water supply systems. Therefore, giving full play to the water supply capacity and carrying out multi-source water supplies are necessary and urgent. This paper gives an overview of the optimal allocation of multi-source for urban water supply concerning variation tendency, modeling methods and facing challenges. Based on the variation tendency of water consumption and water supply pattern in China, Tianjin is taken as a typical city for systematically outlining water supply changes and cause analysis. Subsequently, the modeling methods for proposing the optimal allocation scheme are summarized, which are composed of defining the topological relation, constructing the mathematical model and seeking the optimal solution. Ultimately, the current and emerging challenges are discussed including emergency operation of multi-source water supply and joint operation of water quality and quantity. These summaries and prospects provide a valuable reference for giving full play to the multi-source water supply capacity and carrying out relevant research so as to propose the optimal allocation scheme in urban multi-source water supply systems.China's average per capita share of water resources (about 2100 m 3 ) is only about 25% of the world average [4]. It was reported that of the 669 cities, 400 suffer from insufficient water supply and 110 suffer from severe water shortage; of the 32 cities with a population at or exceeding 1 million, 30 suffer from chronic water shortage; of the 14 coastal open cities, 9 suffer from acute water shortage [5]. Now, China is one of the 13 most water-stressed countries in the world. Apart from the low per capita availability of water resources, there is a mismatch between the spatial distribution of water resources and geographic regions with high population densities, especially in north China where water resources are particularly scarce [6]. By the end of 2010, the 11 coastal provinces lay alone the 1800 km coastal line, occupying 13.7% of China's territory with 43.0% of China's population [7]. The north of the country, similar in land area and population to the south, held only 18% of the total water despite having 65% of the total arable land [8]. In recent decades, accounting for the influence of climate change, land cover change and human activities, drought and water logging disasters, and water ecological security problems have been increasingly prominent; its impact on water availability for humans can jeopardize human life. It is demonst...

“…Technology effects, on the other hand, served to reduce water demand particularly in the early period of their analysis, but making a smaller contribution to reducing use as intensity improvements (reductions) plateaued from 2008 onwards. Shang et al (2017a) undertook a refined Laspeyres analysis of industrial water use in Tianjin, producing results with greater detail on the sectoral contribution to each of the observed effects (structural, activity and technology). They note that the intensity-("Technology") driven changes "are negative, indicating that in the study period, water efficiency improved; but some exceptions within a few industrial sectors during specific time periods are attributed toimproper management or ignorance of water saving" (Shang et al, 2017b(Shang et al, , p.1146.…”

“…The limited application of decomposition techniques may in part reflect: a lack of available water use data at the sectoral level; various holders of water consumption data across a region with no agreement on data sharing; and little prior interest in water issues in water-abundant developed countries ( Duarte and Yang, 2011). Indeed, only four examples of decomposition applied to water use are known to the authors: Cazcarro et al (2013) use SDA to analyse changes in water consumption in Spain between 1980, while Shang et al (2017b and Shang et al (2017a) use the Laspeyres and Log Mean Divisia Index (LMDI) models to decompose industrial water use in Tianjin, China. Kohler (2016) decompose water use in South Africa between 1980 and 2012 -using the Fishers index -between a structural effect and an intensity effect 5 .…”

Future climate scenarios predict significant changes in the availability of water resources at global and regional scales. Knowledge of the possible economic consequences of this are limited by a shortage of data linking economic activity with physical water use. Matching a unique premise-level dataset to economic indicators at industrial/sector level, this paper undertakes a decomposition of changes in industrial water demand for Scotland between 2012 and 2016. Results highlight the importance of taking a sectoral approach, as changes in sectoral water intensity are significant. Furthermore, changes in the structure of the economy, i.e. a move away from water-intensive industries, highlight further reductions in overall water consumption. By considering future scenarios for Scottish water resources, this paper identifies key multi-disciplinary research challenges to address the major obstacles in developing a climate-ready water policy, which also captures the potential economic opportunities for Scotland from an awareness of the role of water in the economy.
