Water-Energy-Food Nexus Management in Rural Communities: A Comprehensive Review from an Engineering Perspective

The water-energy-food (WEF) nexus framework serves as a roadmap for the clear understanding of the complex relationship and interdependency among the water, energy, and food sources which are basic human needs. This paper reviews the application of microgrid control systems for the sustainable management of the WEF nexus in rural communities by focusing on the integration of renewable energy sources. In this work, the existing frameworks on WEF nexus, microgrid energy management models for rural communities, and optimization techniques are critically reviewed. The study further identifies the knowledge gaps that exist in terms of integrated microgrid control strategies for sustainable WEF management and practical implementation within rural communities, showing the potential to develop a holistic framework with ability to realize sustainable resource management and resilience in underserved communities.
