Energy Water Food Nexus (EWFN) presents a valuable approach to achieving food security with a particular focus on sustainably balancing the growing demand for food with the constrained production capacity enabling supply streams. Three main pathways to overcome food security challenges and the role of Life Cycle Assessment (LCA) were identified: employing sustainable production methods in agriculture, changing diets, and reducing waste in all stages of the food chain. This work discusses how Life Cycle Assessment (LCA) might be applicable for creating the evidence-base to foster such desired shifts in food production and consumption patterns.
