“Water Security as an Essential Component of the Defense Industrial Base” is the latest perspective piece by DKI APCSS’s own DR. Deon Canyon. The article highlights the important role water security plays in maintaining military readiness and national defense. The defense industrial base, which relies on water for manufacturing, cooling, and sustaining installations, faces significant vulnerabilities due to water scarcity driven by climate change, population growth, and resource competition. Canyon warns that disruptions in water supply could increase costs, reduce productivity, and hinder military operations, especially in water-stressed regions like the Indo-Pacific. He emphasizes the growing reliance on water-reliant AI computer systems in defense and calls for governments and industries to invest in water-efficient technologies, diversify water sources, and enhance water resilience in military facilities. The article shows that safeguarding water security is vital to sustaining defense capabilities and protecting national security.
