Indigenous territories in Ecuador’s Amazon maintained forest quality comparable to, and in some measures better than, formally protected government reserves, according to a study published on 8 September by researcher Fernando Troya, conducted while he was a doctoral student at KU Leuven University in Belgium. The research used satellite data to track vegetation health, forest disturbance and drought resilience across three different governance models in the region.
The study found that indigenous territories without formal conservation agreements showed the greatest proportion of areas with positive long-term vegetation trends of any governance category examined, ahead of both community-protected forests and state-run reserves. Government-protected forests, by contrast, showed the most degradation overall, with 78.6% of monitored areas in northern Ecuador showing declining vegetation compared with 57.1% in the south, a difference researchers linked to greater road access, population pressure and oil development in the north.
Drought resilience set community forests apart
Community-protected forests showed particular strength in one specific test: resilience following the severe 2015-2016 El Nino drought, one of the most intense on record for the region. Areas under community governance recovered vegetation health after that drought more consistently than either indigenous territories without formal protection status or state reserves, suggesting that active, locally organised management can offer distinct advantages during acute climate shocks even when longer-term trends favour other governance models.
Troya framed the findings as evidence for a broader argument gaining traction in conservation science: protection outcomes depend as much on governance and local participation as on the formal legal status of the land itself. “Conservation is not only about drawing lines on a map,” he said. “It is also about governance, local participation, and creating systems that help people manage forests sustainably.”
Relevance beyond Ecuador
The findings add to a growing body of research across the Amazon basin and other tropical forest regions finding that indigenous and community land tenure often delivers conservation outcomes on par with, or exceeding, strictly protected reserves, despite receiving a smaller share of international conservation funding. That funding gap has become a recurring point of criticism from indigenous rights groups, who argue that formal recognition of land rights would be a more cost-effective conservation investment than expanding state-run protected areas alone.
The pattern also resonates with findings from a separate area of climate research this month: a global coral reef assessment found that some naturally occurring refugia, reef areas that have so far escaped the worst bleaching, are increasingly being studied as models for what effective, low-intervention protection can look like when conditions allow ecosystems room to self-regulate. Troya’s Ecuador findings suggest a parallel logic may apply on land, where indigenous governance systems, developed over generations, appear to function as a comparably effective form of environmental stewardship.
Ecuador’s Amazon remains under continued pressure from oil extraction, road expansion and agricultural encroachment, and Troya’s study does not suggest indigenous governance alone can withstand unlimited external pressure. What it does suggest, he said, is that policies treating indigenous land rights as a conservation afterthought rather than a primary tool may be underestimating one of the more effective mechanisms already available for protecting the forest.
Troya’s methodology, which relied on publicly available satellite imagery rather than costly ground surveys, offers a template other researchers could apply relatively cheaply to test whether the Ecuador findings hold across other Amazon basin countries, including Brazil, Peru and Colombia, where land tenure disputes between indigenous communities and state authorities remain active and, in some cases, contentious. Extending the analysis regionally would help clarify whether Ecuador’s result reflects a broader Amazon-wide pattern or specific local conditions.
