|Water-Energy-Food Nexus: A Provision to Tackle Urban Drought Unprecedented urban growth adds pressure on the finite water resources to meet the growing demands. Urban does not only account large direct consumption of water, but also account large water footprint because of consumption of water-intensive food and high-energy consumption. Consequently, urban areas have experienced competition among various water users, particularly in the dry season. Failure of conventional approach to manage drought risk has translated realization urgency of integrated approach. Water-energy-food nexus (WEFN) approach emerges as an integrated tool to manage increasing water crisis in the context of rapid urban growth through facilitating multi-sectoral cooperation at both in-boundary and trans-boundary scales. Taking selected good practices of nexus around the world, this chapter argued that through realizing synergies across the urban water-energy-food system, cities could deliver inclusive growth, even with increasing drought risk. Scale-up of WEFN approach needs to be supported by enabling conditions. Mainstreaming of synergistic interactions across the WEFN is determined by inter-sectoral coordination, common vision, harmonizing policies, and the alignment of strategies and regulations, and economic incentives.||Water-Energy-Food Nexus: A Provision to Tackle Urban Drought||Mitra, Bijon Kumer; Shaw, Rajib; Yan, Wanglin; Takeda, Tomoko||Book Section||academic||2019||

|Development of an urban FEW nexus online analyzer to support urban circular economy strategy planning Growth of urban population around the world and, particularly, within urban areas, has placed various pressing challenges on Food, Energy, and Water (FEW) such as food security, water safety as well as energy scarcity and so on. Current studies on urban FEW nexus are mainly focused on the correlation analysis of elements by pairs, while these works are developed separately. With respect to the methods, the existing researches mostly adopt the bottom-up approach, accounting for the direct relationship between the individual production sectors. While the associations between the internal elements of the system still lack of simulation. In this study, we aim at developing an online open access tool for cities, the Urban Circular Economy Calculator (UCEC), which enables to develop different circular economy scenarios associated to FEW management. UCEC v1.0 uses Beijing data as test case. In particular, more than 20 circular economy policies related on food, energy and water are selected and divided into 6 categories. Long-term simulations on the social, economic and environmental impacts are provided to test the trajectories of policy effects. Being an open access tool, UCEC can be used also for supporting participatory processes as an urban management instrument. The solution is economically and financially feasible, due to the low level of technical requirements. The necessity of such a tool is proved by the societal need of transition toward a low-carbon and sustainable framework, which can be effectively supported by the introduction of circular economy. This transition, such as the idea behind UCEC, should preserve (or even improve) the societal wellbeing, while increasing basic resources (i.e.: FEW) accessibility, security and preservation.||Development of an urban FEW nexus online analyzer to support ...||Xue, Jingyan; Liu, Gengyuan; Casazza, Marco; Ulgiati, Sergio||Journal Article||academic||2018||

|Urban metabolism: Measuring the city's contribution to sustainable development Urban metabolism refers to the assessment of the amount of resources produced and consumed by urban ecosystems. It has become an important tool to understand how the development of one city causes impacts to the local and regional environment and to support a more sustainable urban design and planning. Therefore, the purpose of this paper was to measure the changes in material and energy use occurred in the city of Curitiba (Brazil) between the years of 2000 and 2010. Results reveal better living conditions and socioeconomic improvements derived from higher resource throughput but without complete disregard to environmental issues. Food intake, water consumption and air emissions remained at similar levels; energy use, construction materials and recycled waste were increased. The paper helps illustrate why it seems more adequate to assess the contribution a city makes to sustainable development than to evaluate if one single city is sustainable or not.||Urban metabolism: Measuring the city's contribution to sustainable development||Leonardo S.
