Given the rapid development within China, the inequality of available water resources has been increasingly of interest. Current methods for assessing water stress are inadequate for province‐scale rapid monitoring. A more responsive indicator at a finer scale is needed to understand the distribution of water stress in China. This paper selected Defense Meteorological Satellite Program Operational Line‐scan System night‐time stable lights as a proxy for water stress at the province level in China from 2004 to 2012, as night‐time lights are closely linked with population density, electricity consumption and other social, economic and environmental indicators associated with water stress. The linear regression results showed the intensity of night‐time lights can serve as a predictive tool to assess water stress across provinces with an R2 from 0.797 to 0.854. The model worked especially well in some regions, such as East China, North China and South West China. Nonetheless, confounding factors interfered with the predictive relationship, including population density, level of economic development, natural resource endowment and industrial structures, etc. The model was not greatly improved by building a multi‐variable linear regression including agricultural and industrial indicators. A straightforward predictor of water stress using remotely sensed data was developed.

“…Metrics based on urban metabolism approaches have also been reviewed in the literature. Ravalde and Keirstead (2017) [22] propose performance-based metrics derived from urban metabolism and exergy approaches to quantify multi-resource flows in cities and investigate pathways for sustainable resource use. Thomson and Newman (2018) [23] explore how urban metabolism approaches can be employed to assess the sustainability of different urban fabrics.…”

Embedding Circular Economy Principles into Urban Regeneration and Waste Management: Framework and Metrics

In a highly urbanised world, cities have become main centers of resource consumption and generation of waste. The notion of the circular economy (CE) identifies strategies for slowing and narrowing resource use through the prevention of waste, improvement of resource use, and substitution of the use of primary resources with recovered materials (and energy). The literature has recently started to explore the concept of circular cities, and a number of cities around the globe have adopted circular economy strategies. Urban regeneration can play a critical role in enabling more circular loops of resources and contribute to more sustainable urban environments; however, there is a lack of contributions in the literature that explore the circularity of urban regeneration projects. The aim of this research is to address this gap by providing a framework and metrics to embed circular economy principles into urban regeneration. The proposed framework and set of metrics are then applied to a case study in West London to quantitatively assess CE implications and point to opportunities to increase circularity. Three main scenarios are developed to assess resource impacts of different waste strategies. The maximizing recycling scenario suggests that over 65% recycling and just under 35% energy recovery could be achieved for the area. However, findings suggest potential trade-offs between strategies centered around energy recovery from waste and strategies that prioritise recycling of recyclable fractions from waste. The three scenarios are then assessed against the CE metrics proposed. Again, here, ‘maximising recycling’ better aligns with the proposed CE metrics and contributes to cutting around 50% of GHG emissions associated with management/disposal of residual waste while increasing opportunities for resource recovery. Finally, some conclusions are drawn pointing to pathways to maximise optimal resource use and infrastructural provision in urban regeneration.

Urban metabolism analyzes the supply and consumption of nutrition, material, energy, and other resources within cities. Food, water, and energy are critical resources for the human society and have complicated cooperative/competitive influences on each other. The management of interactive resources is essential for supply chain analysis. This research analyzes the food-water-energy system of urban metabolism for sustainable resources management. A system dynamics model is established to investigate the urban metabolism of food, water, and energy resources. This study conducts a case study of Shihmen Reservoir system, hydropower generation, paddy rice irrigation of Taoyuan and Shihmen Irrigation Associations, and water consumption in Taoyuan, New Taipei, and Hsinchu cities. The interactive influence of the food-water-energy nexus is quantified in this study; the uncertainty analysis of food, water, and energy nexus is presented.
