A historical data analysis of water‐energy nexus in the past 30 years urbanization of Wuxi city, China

Abstract

In this article, the historical data of water and energy consumption of Wuxi City, one of the main cities in the Taihu Lake Basin region in Eastern China, was reviewed and analyzed to map their dynamic changes in the rapid urbanization process of the past 30 years, as the urbanization ratio changed from 24.7% (1983) to 73.7% (2013). Results show that (a) water and energy resources have generally been managed separately in overall social‐economic development planning of the city and region; and (b) the increase of water and energy consumption closely correlates with the rate of urbanization and urban growth. A Water‐Energy Nexus Chart (WENC) is proposed as a potential tool to provide a snapshot on water and energy management to show relative efficiency of water use in energy production and energy use in water treatment and supply provision. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 46–55, 2018

Integrative technology hubs for urban food-energy-water nexuses and cost-benefit-risk tradeoffs (II): Design strategies for urban sustainability

“…In existing nexus studies, several useful methods were adopted for analyzing and correlating different nexus backgrounds. The common methods include mathematical modeling (Kenway et al, 2011;Wang et al, 2017;Xie et al, 2018), life cycle assessment (LCA) (Meldrum et al, 2013;Wang et al, 2018;Bozeman et al, 2019), network modeling (Zimmerman et al, 2018), agent-based modeling (Bieber et al, 2018), spreadsheet models using numerical equations (Wilkinson, 2000), surveys with factor analysis (Bullock & Bowman, 2018), system dynamics model (Hussien et al, 2017), and geographic information system (GIS) (Gurdak et al, 2017;Uddameri & Reible, 2018). Among them, LCA is becoming a popular method (Wang & Zimmerman, 2011;Mannan et al, 2018), as LCA considers both direct and indirect inputs and outputs of resources (Retamal et al, 2008;Wang et al, 2018).…”

City-level water-energy nexus in Beijing-Tianjin-Hebei region

“…Yet city-level water-energy nexus studies are relatively limited. In China, Xie et al (2018) [58] used historical data of water and energy consumption of Wuxi city, a main city in Taihu Lake Basin region in Eastern China, to build a water-energy nexus chart in order to map their dynamic changes in the rapid urbanisation process of the past years. Chen and Chen (2016) [59] synthesised connections between water use and energy consumption, and merged them into urban nexus network in Beijing.…”

Análise Da Sustentabilidade Da Prestação Dos Serviços Do Sistema De Abastecimento De Água No Município De Belém-Pa

“…Nesse contexto, o conceito de sustentabilidade ganhou destaque, principalmente a partir da década de 80 com as conferências ambientais de Estocolmo em 1972, Eco-92 (Rio-92) em 1992, Rio+10 em 2002 e a Rio+20 em 2012, sendo inserido no âmbito das cidades e em seus serviços, para permitir a constante evolução das relações econômicas e sociais, sem impactar negativamente o meio ambiente, tornando-se uma busca constante e um desafio necessário para o desenvolvimento adequado das cidades atuais (FEIL; SCHREIBER, 2017). Xie et al (2017) apontam que a segurança hídrica e a disponibilidade de água para consumo humano são desafios em escala mundial para o processo de urbanização sustentável. No Brasil, a falta de sustentabilidade dos serviços de abastecimento de água reflete na dificuldade de ampliação dos sistemas e no elevado déficit de atendimento.…”
