Special Issue Information

Dear Colleagues,

The Energy-Water-Food (E-W-F) Nexus (also known as the W-E-F Nexus and the F-E-W Nexus) provides a framework for the integration of planning, management and governance.  It also can provide a focus for innovation and technical development in resource management especially where the innovations address the interactions of two or all of the sectors or support multiple sectors.  Examples of areas where innovation is emerging or still needed include optimizing use of food, water and energy resources; national and global security of access to food, water, and energy; addressing environmental change and adaptations to change; enabling the achievement of SDGs by improving support for decision-making and indicator monitoring; integrated infrastructure for supporting multiple sectors, and enhancing the opportunities and benefits of new technologies such as biotechnology, robotics, AI and information technologies, among others.

This special issue is seeking papers that will discuss how new technologies and innovations can be used in the E-W-F Nexus. Examples of successes are sought that address issues that are raised in assessments and solutions that are being implemented within the E-W-F Nexus framework. The context of geographical and economic factors related to these innovations and the experiences in engaging implementation agents and communities to adopt these innovations and technical solutions are also welcomed. Papers that identify challenges and benefits of new solutions are also considered, especially where they assess administrative obstacles, ownership issues, policy barriers, and the limitations of technology.

Food, energy, and water (FEW) are essential for human health and economic development. FEW systems are inextricably interlinked, yet individualized and variable. Consequently, an accurate assessment must include all available and proposed FEW components and their interconnections and consider scale, location, and scope. Remote Alaska locations are examples of isolated communities with limited infrastructure, accessibility, and extreme climate conditions. The resulting challenges for FEW reliability and sustainability create opportunities to obtain practical insights that may apply to other remote communities facing similar challenges. By creating energy distribution models (EDMs), a methodology is proposed, and a tool is developed to measure the impacts of renewable energy (RE) on small FEW systems connected to the microgrids of several Alaska communities. Observing the community FEW systems through an energy lens, three indices are used to measure FEW security: Energy–Water (EW), Energy–Food (EF), and Sustainable Energy (SE). The results indicate the impacts of RE on FEW infrastructure systems are highly seasonal, primarily because of the natural intermittence and seasonality of renewable resources. Overall, there is a large potential for RE integration to increase FEW security as well as a need for additional analysis and methods to further improve the resiliency of FEW systems in remote communities.

Floating solar photovoltaic (FPV) systems have become an increasingly attractive application of photovoltaics (PV) because of land-use constraints, the cost of land and site preparation, and the perceived energy and environmental co-benefits. Despite the increasing interest in FPV systems, a robust validation of their suggested co-benefits and impacts on the nexus of energy, water, and food (EWF) systems is lacking. This information gap makes it challenging for decision makers to justify its adoption—potentially suppressing FPV deployment. To address this gap and to help de-risk this PV deployment opportunity, we (1) review the suggested co-benefits of FPV systems with a focus on the impacts that could alleviate pressures on EWF systems and (2) identify areas where further research is needed to reduce uncertainty around FPV system performance. Our review reveals that EWF nexus-relevant co-benefits, such as improved panel efficiency and reduced land usage, are corroborated in the literature, whereas others, such as water quality impacts, lack empirical evidence. Our findings indicate that further research is needed to quantify the water-related and broader economic, environmental, social, sustainability, justice, and resilience co-benefits and impacts of FPV systems.
