The article presents a framework to improve water, energy, and food security by efficiently allocating resources. By using a mathematical model, the researchers found that by optimizing resource allocation, the security of these sectors can be significantly increased. In a case study in Mexico, the approach led to a 6% increase in water security, 56% in energy security, and 26% in food security. Overall, the water-energy-food nexus security was boosted by 27%. This framework can be applied to other regions to enhance resource security.
