Health Risk Has Moved Across Systems. Our Institutions Haven’t

We still talk about health crises as if they begin in hospitals: a spike in cases, an alert, a response. More often, they begin much earlier—in degraded ecosystems, stressed food systems, rising antimicrobial resistance (AMR) and fragmented coordination across systems still managed separately. That’s the core insight behind approaches like “One Health,” the health of people, animals and ecosystems is interdependent, not adjacent.

That shift is no longer niche. It now underpins how health risk is increasingly understood and governed. The Quadripartite—the World Health Organization (WHO), the Food and Agriculture Organization of the United Nations (FAO), the United Nations Environment Program (UNEP) and the World Organization for Animal Health (WOAH)—has set out a shared agenda through the Joint Plan of Action, and the WHO Pandemic Agreement adopted in May 2025 reflects this integrated approach to prevention and preparedness.

Institutions understand that health risk is interdependent. Most still don’t operate on its terms—and that gap is where risk now compounds, cutting across public, private and multilateral systems alike.

That matters because the risk landscape has already shifted. More than 75% of emerging infectious diseases in humans are zoonotic, according to WOAH, while UNEP identifies food systems as a major driver of biodiversity loss and environmental degradation—the conditions under which spillover risk rises. These aren’t separate pressures; they move across the same system. This is what systemic health risk looks like in practice.

The economics reinforce it. FAO estimates the hidden costs of agrifood systems at around 10% of global GDP—a systemic risk, not just an agriculture issue.

The same is true of AMR. It’s still too often treated as a medical or pharmaceutical problem, when in reality it sits at the intersection of human health, animal health, food systems and the environment. In 2021, bacterial AMR was associated with an estimated 4.71 million deaths globally, including 1.14 million deaths directly attributable to resistance, according to WHO reporting. That is what system failure looks like when the warning signs are distributed across sectors, but accountability is not.

From Understanding to Execution

The next phase of this shift is less about scientific understanding than institutional capability. We already know the system is interconnected. The harder question is whether leaders can govern that interdependence before it turns into a crisis. UNEP’s 2024 foresight work underscores exactly that: the risk now is not simply a lack of information, but a failure to connect early shifts across systems quickly enough to act. That is a different challenge from response. It is a challenge of anticipation.

The trajectory from here is not uncertain—but it is uneven. Strip it back, and the next five years come down to two variables: the strength of ecological transition and the strength of cross-sector governance. If both remain weak, fragmentation deepens and risk compounds. If ecological transition advances but institutions stay siloed, some environmental indicators improve while disease and food security risks remain poorly managed. If governance improves but food systems and land use remain destructive, institutions may get better at containment while the drivers of instability continue to build. The most resilient future is the one in which both move together: better surveillance, stronger coordination and real progress on the upstream conditions that shape health outcomes in the first place.

We are no longer dealing with isolated health threats. We are managing system-level risk—whether our institutions are designed for it or not. The risk is no longer that we don’t see these pressures. It’s that we still manage them as if they sit in separate systems.

There are early signs of movement in that direction, but they remain at the level of coordination, not full system integration. In February 2025, the Quadripartite launched a Regional One Health Coordination Mechanism and Action Plan for the Middle and Near East, North Africa and Eastern Mediterranean regions. Its significance is institutional, not just technical. It reflects growing recognition that zoonotic disease, AMR and environmental degradation cannot be managed through parallel systems that meet only once the emergency is already visible.

Similar coordination frameworks are emerging elsewhere—across Europe, Asia and the Americas—reflecting a broader shift toward more integrated approaches to managing systemic health risk.

What This Means for Leadership

For governments, companies and institutions, this is no longer theoretical. Four shifts stand out:

• Invest upstream
  The biggest risks are being shaped before they show up in health data—in food systems, land use, veterinary capacity and environmental resilience. That’s where investment has to move.
• Break the silos—structurally
  Cross-sector coordination can’t be ad hoc—across government, industry or global systems. It has to be built into how decisions are made.
• Rethink early warning
  Surveillance now needs to span human, animal and environmental signals, not sit in separate systems.
• Change the narrative
  Prevention is harder to communicate than crisis. But without it, institutions default back to reaction.

There is also a deeper question beneath this: whether coordination needs to be institutional at all. In other sectors, complex systems are not aligned by redesigning each component, but by introducing layers that allow them to operate together. That logic is beginning to emerge here—with data integration, shared platforms and artificial intelligence starting to act as connective tissue across fragmented systems.

That does not replace institutions. But it may change how coherence is achieved when institutional change moves more slowly than the risks themselves.

The future of health has already changed. It is interdependent, systemic and shaped far upstream from the point where most institutions still begin to act. The question is no longer whether we understand that. It’s whether we are willing to reorganize around it.

Because if we don’t, the next crisis won’t expose a lack of knowledge. It will expose a failure to act on what we already know.
