Nature’s Overlooked Role in National Security

Why It Matters

Ecological breakdown undermines the foundations of food, water and health security, creating flashpoints that can destabilize states. Ignoring these risks leaves defense and intelligence agencies blind to a growing source of conflict.

Key Takeaways

• Cod Wars showed ecosystem disputes can trigger armed conflict
• Study of 27 cases links ecosystem loss to political instability
• US security strategy largely omits biodiversity and ecosystem risks
• EU integrates ecological threats into national‑security planning
• Anti‑science policies erode early warning systems and crisis response

Pulse Analysis

The Cod Wars of the 1970s are a reminder that natural resources can spark geopolitical tension. S. NATO base. Today, climate‑driven droughts, biodiversity loss, and environmental crime are replicating that pattern on a global scale, turning what once seemed a local fisheries issue into a strategic security concern.

Scholars now describe this as ‘ecological security,’ a framework that treats ecosystem services as essential pillars of national defense. A recent assessment published in *Nature‑based Solutions* examined 27 historical case studies where ecosystem disruption amplified social unrest and political instability. The authors identified five critical domains—food, water, health, natural disasters, and environmental crime—through which nature directly influences a nation’s security posture. Their findings show that the United States remains an outlier, with its national‑security strategy barely mentioning biodiversity or ecosystem services, while the European Union has begun embedding ecological risk analyses into defense planning. Concurrently, anti‑science actions such as the dismissal of the National Science Board weaken early‑warning capabilities and model reliability.

Integrating Earth‑system science into intelligence assessments is no longer optional; it is a prerequisite for resilient governance. Policymakers should institutionalize cross‑agency task forces that translate ecological forecasts into actionable security metrics, and allocate funding for monitoring networks that track habitat loss, illegal wildlife trade, and climate extremes. Academic‑military partnerships, like the National Intelligence Council workshops that sparked this research, can bridge the cultural gap between ecologists and defense planners. If governments adopt such collaborative structures, the emerging ‘nature‑security’ paradigm could shift from a warning signal to a strategic advantage.
