Nexus Framing of Sustainability Issues: Feasibility, Synergies, and Trade-Offs in Terms of Water-Energy-Food.

Multisectoral integration has been at the core of sustainability debates and is continuously rearticulated through different concepts. Following the 2007–2008 financial, food, and energy crises, a new concept, the water–energy–food nexus, gained prominence to identify trade-offs and synergies between water, energy, and food systems and guide the development of cross-sectoral policies. The nexus is essentially a systems-based perspective that explicitly recognizes these three systems as both interconnected and interdependent, and thus integrated approaches are required that move beyond sectoral, policy, and disciplinary silos. The nexus is also a political process, one in which the interplay of different types of power, as well as the actors wielding them, is not just a procedurally technical one. This tension between the nexus as a complex system and the nexus as a political process constitutes the core debating idea, in terms of feasibility, methods, and theory, in this article.
