The historic pandemic faced by the international community today boldly demonstrates the complexity and interconnectedness of the resource challenges we must better understand and address in the future. Further complexity is observed when accounting for the impact of compounded shocks related to natural disasters and forced migration around the world. Effectively addressing these challenges requires the development of research that cuts across disciplines and innovates at their interfaces, in order to develop multifaceted solutions that respond to the social, economic, technological, and policy dimensions of these challenges. Water, energy, and food systems are tightly interconnected. They are faced with pressures of varying natures and levels of urgency which need to be better understood, especially as nations work toward achieving the UN 2030 Agenda’s Sustainable Development Goals by 2030. This paper will review existing models and knowledge gaps related to water-energy-food (WEF) nexus models, as well as models for quantifying the impact of migration, pandemics, and natural disasters on this resource nexus. Specifically, this paper will: (1) explore the WEF nexus literature and identify gaps in current assessment tools and models; (2) explore the literature on tools and models for predicting the shocks of migration, natural disasters, and pandemics; (3) identify interconnections between water, energy, and food systems and the identified shocks; (4) develop a common framework that provides a road map for integrating those shocks in WEF nexus analysis; (5) provide recommendations for future research and policies moving forward.

Lebanon faces a mix of underlying political and economic challenges, shocks, and triggering events that threaten the sustainability and resilience of its interconnected resource systems. The complex nature of these pressures begs for a systems approach to better understand the existing interconnections and to support the co-creation of cross-sectoral solutions to address them. This article specifically aims to: 1) conduct a scoping review of the existing literature and current events to identify interconnections between water-, energy-, and food-related challenges as they relate to the underlying conditions and triggering events at play in the context of Lebanon; 2) highlight ways in which the Water-Energy-Food (WEF) Nexus is a useful lens through which to understand and act upon issues at different scales; and 3) identify emergent themes including decentralization and systems thinking and their roles as catalysts toward more resilient resource systems. The examination concludes with two main recommendations: first, to create platforms and opportunities for interactive resource planning and decision making to facilitate systems-thinking for top-down WEF management; and second, to empower decentralized initiatives at the local level to build resilient, bottom-up solutions to WEF challenges.
