“…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.…”
