Conservation has long carried a colonial legacy: draw a boundary, post a sign, and keep people out. But a sweeping new study challenges that old playbook. Researchers found that rainforest areas managed by Indigenous communities or local residents can be just as effective—or even more so—at preventing deforestation than exclusionary parks.

Published in Nature Sustainability, the research analyzed 11 million square kilometers of rainforest across 2,000+ protected areas in 66 countries.

The takeaway? Human presence doesn’t doom forests—bad governance does.

🌎 “People-in” models of conservation—those that include Indigenous stewardship, co-management, or sustainable livelihoods—performed as well or better than strict protected areas with full restrictions.

🌱 Community-managed forests were especially effective in regions with good governance and legal recognition of Indigenous land rights.

📉 In some “people-out” parks, deforestation rates were actually higher—likely due to poor enforcement, political conflict, or local resentment.

🤝 It validates Indigenous knowledge – Many communities have lived sustainably in forests for generations. Now science is catching up to that wisdom.

🧭 It reframes protection – Instead of seeing humans as threats to nature, we can see them as allies in its care.

📣 It supports climate justice – Rainforest protection shouldn’t come at the cost of human rights. Empowered communities are often the best stewards of biodiversity and carbon storage.

If we want to protect the planet’s last great forests, we shouldn’t wall them off—we should listen to the people who know them best.
