The Water–Energy Nexus of Megacities Extends Beyond Geographic Boundaries: A Case of Beijing

Abstract: The water–energy nexus (WEN) is dynamic and complicated in megacities, most of which are challenged by water scarcity and the mandate to reduce energy consumption. A salient feature of water and energy services in megacities is that they are supported by a web of regional infrastructure, extending far beyond the geographic boundaries of the cities, resulting in a strong dependence on resources imported from outside. Understanding the WEN of megacities has implications not only for more efficient resource utili… Show more

“…A more comprehensive illustration of existing nexus research is shown in Figure 6, in which black lines represent a focus on the study of a particular resource (e.g., food, energy, or water), yellow lines indicate the study of integrated systems with two principal resources, and gray dashed lines emphasize the interlinkages of subsections of different nexuses. In terms of focus and level of integration, 29 papers focused on the FEW nexus, but these mostly aimed to conduct general analysis and systematic review, whereas 10 papers focused on water (Larsen & Drews, 2019;Rosa & D'Odorico, 2019), 5 on food (Abdelkader et al, 2018;Neto et al, 2018;Zhang, Campana et al, 2018), 4 on energy (Yuan et al, 2018;Ahjum et al, 2018;Whitney et al, 2019), 9 on water-energy nexus (Engstr€ om et al, 2017;Wang et al, 2017;Liu et al, 2019), 2 on energyfood (Hanes et al, 2018), and 1 on water-food (Zhang & Vesselinov, 2017). The rest of the articles applied nexus research from various angles.…”

“…The urban population is increasing and is estimated to reach 70% of the global total population by 2050. 114 Furthermore, cities are expected to consume 75% of the world's total energy. 114 Therefore, providing sustainable and renewable energy for cities is one of the most urgent issues for the development of human civilization.…”

“…For instance, Hu et al [66] assess the WEN in Beijing, focusing on the water used in electricity production and supply, as well as the electricity used for water supply, treatment, utilization, and post-use. Liu et al [67] explore the spatial dimension of the WEN of Beijing, and find that more water for energy is consumed outside Beijing's boundaries than within its boundaries. They also highlight that meeting water policy objectives implies an increase in energy use, making it harder for Beijing to meet its carbon emission control targets.…”
