Health cannot be separated from the health of ecosystems
In May 2026, the World Health Organization brought forward a truth that global environmental policy has long overlooked: the healers, herbalists, and knowledge keepers of Indigenous communities are not bystanders to the planetary crisis, but among its most consequential casualties. Traditional medicine has never separated human health from the health of the living world, and as climate change, biodiversity loss, and land degradation accelerate, they are erasing not only medicinal species but the accumulated wisdom of millennia. What is at stake is not sentiment or heritage alone — it is the primary healthcare system for communities across the globe, and a tested model of ecological stewardship that modern institutions have yet to replicate.
- Medicinal plants are vanishing as habitats shrink, and centuries-refined treatments are losing potency as soils shift and seasons change.
- Indigenous knowledge systems — encoding which plants heal, how to harvest, when to gather — face irreversible loss as communities are displaced and younger generations leave for cities.
- For many communities worldwide, traditional medicine is not a cultural preference but the only healthcare system available, making its erosion a direct health emergency.
- The WHO is pushing to embed traditional medicine into the Rio Conventions — the international frameworks on climate, biodiversity, and desertification — arguing their siloed implementation is a strategic failure.
- As of mid-2026, the integration of Indigenous knowledge into global environmental policy remains far more aspiration than action, with funding, territorial protection, and decision-making power still largely withheld from communities.
In May 2026, the World Health Organization convened a side event to argue something that global climate and conservation policy has consistently ignored: traditional medicine and Indigenous knowledge systems are not peripheral to the planetary crisis — they are among its most urgent casualties, and potentially among its most powerful solutions.
The logic is simple but cuts against how health policy is typically made. Climate change, biodiversity collapse, and land degradation are dismantling the ecosystems that traditional medicine depends on entirely. Medicinal plants are disappearing. The potency of treatments refined over centuries is shifting as growing conditions change. And the knowledge itself — which plants heal which ailments, how to harvest sustainably, how to prepare remedies — is being lost as communities face displacement and the landscapes that encode this wisdom are transformed beyond recognition.
The WHO positioned traditional medicine as a bridge across the three Rio Conventions — the international agreements on climate change, biodiversity, and desertification — frameworks that are rarely discussed together and almost never include traditional medicine in their implementation. That omission, the WHO argued, is not an oversight but a strategic failure.
The human stakes are concrete. For many Indigenous communities, traditional medicine is not a cultural preference but the only healthcare system available. When medicinal species vanish and knowledge transmission is interrupted, the result is not cultural loss alone — it is a health emergency, stripping communities of treatments that have sustained them for millennia and of the autonomy to care for themselves.
The WHO's case is ultimately pragmatic: Indigenous knowledge systems have integrated human health and ecological stewardship simultaneously for thousands of years, modeling what modern medicine and conservation have struggled to achieve separately. But for that recognition to translate into change, it would require governments to center traditional medicine in climate action and biodiversity policy, protect the territories where medicinal species grow, and grant Indigenous communities genuine decision-making power. That transformation, as of mid-2026, remains largely unrealized.
The World Health Organization convened a side event in May 2026 to make a case that has been largely absent from global climate and conservation discussions: that traditional medicine and Indigenous knowledge systems are not peripheral to solving the planet's environmental crises, but central to them.
The premise is straightforward, yet it cuts against how most health policy is made. When governments and international bodies talk about climate change, biodiversity collapse, and land degradation, they rarely mention the healers, herbalists, and knowledge keepers whose practices depend entirely on the ecosystems those crises are unraveling. Health, in the conventional framing, is treated as separate from nature. But traditional medicine has never operated under that illusion. Its survival, its effectiveness, its very transmission from one generation to the next—all of it rests on the health of the living world around it.
The WHO event positioned traditional medicine as a bridge connecting three major United Nations frameworks: the Convention to Combat Desertification, the Framework Convention on Climate Change, and the Convention on Biological Diversity. These are the Rio Conventions, the international agreements meant to address the three dimensions of planetary breakdown. Yet they are rarely discussed as a unified problem, and traditional medicine is almost never mentioned in their implementation.
What the WHO was signaling is that this omission is a strategic failure. The triple crisis—climate change, biodiversity loss, and land degradation—is not an abstract threat to traditional medicine. It is an immediate, material one. Medicinal plants are disappearing as habitats shrink and shift. The potency of treatments that have been refined over centuries is changing as growing seasons alter and soil composition shifts. And perhaps most critically, the knowledge systems themselves—the accumulated understanding of which plants heal which ailments, how to harvest sustainably, when to gather, how to prepare remedies—are being lost as Indigenous communities face displacement, as younger generations migrate to cities, as the ecosystems that encode this knowledge are transformed beyond recognition.
The human dimension here is not incidental. Indigenous communities across the globe rely on traditional medicine not as a cultural preference but as a primary healthcare system. For many, it is the only healthcare system available. When medicinal species vanish, when the knowledge that teaches how to use them is interrupted, the consequences are not merely cultural loss. They are health emergencies. Communities lose access to treatments that have sustained them, sometimes for millennia. They lose the autonomy to care for themselves.
The WHO's framing suggests that recognizing traditional medicine as a critical link in addressing planetary crises is not a matter of cultural respect or romantic preservation. It is pragmatism. Indigenous knowledge systems have sustained human health and managed ecosystems simultaneously for thousands of years. They represent, in effect, a tested model for the integration of health and ecological stewardship that modern medicine and modern conservation have struggled to achieve separately.
For this recognition to matter, though, it would need to reshape how the Rio Conventions are actually implemented. It would require governments and international bodies to center traditional medicine and Indigenous knowledge in climate action, biodiversity protection, and land restoration efforts. It would mean funding research into traditional practices, protecting the territories where medicinal species grow, and ensuring that Indigenous communities have decision-making power in conservation and climate policy. As of mid-2026, that integration remains more aspiration than reality.

The Hearth Conversation Another angle on the story
Why does the WHO think traditional medicine belongs in climate policy? Isn't that a health issue, not an environmental one?
Because traditional medicine can't exist without healthy ecosystems. A healer's knowledge is useless if the plants they depend on are gone. Climate change and biodiversity loss aren't just environmental problems—they're health emergencies for the communities that rely on traditional medicine.
But surely modern medicine can substitute? If a medicinal plant disappears, can't we synthesize the compound?
Sometimes, maybe. But that misses the point. Traditional medicine systems are integrated—they're about which plant, harvested when, prepared how, given in what context. That knowledge took centuries to develop. And for many Indigenous communities, it's the only healthcare they have access to. Losing it means losing health security.
So the WHO is saying these three UN conventions—on climate, biodiversity, desertification—should all be talking to each other?
Exactly. Right now they operate in silos. But they're all threatening the same thing: the survival of medicinal species and the transmission of the knowledge about how to use them. If you want to actually implement these conventions, you have to include the people whose survival depends on the ecosystems they're meant to protect.
What would that actually look like in practice?
It would mean Indigenous communities having real decision-making power in conservation and climate projects. It would mean funding research into traditional practices, not to extract and patent them, but to support their continuation. It would mean protecting the territories where medicinal species grow. Right now, that's mostly not happening.
