Kayapo territory, spanning approximately 9.4 million hectares across the southeastern Amazon, is one of the largest continuously protected Indigenous forest landscapes on Earth. Here, the forest is not a fragment. It is whole, connected, and alive.
Stability at Scale
Across the Amazon and beyond, once-continuous ecosystems are being fragmented into smaller and smaller patches broken apart by roads, agriculture, mining, and expanding infrastructure. What remains are often isolated fragments, no longer large enough to sustain the full systems that once thrived there. But in some places, the original scale still exists.
For decades, the Kayapo people have defended their lands against encroaching deforestation: from illegal logging and gold mining to expanding agriculture. Through strong governance systems, including territorial monitoring and guard posts, they have maintained the integrity of their forest across millions of hectares.
This continuity creates stability across a vast, intact landscape. It allows the forest to function as a system, not just a collection of trees, but a living, interconnected whole. And it is precisely this kind of large-scale stability that makes forests so important for climate stability.
Kayapo territory stores an estimated 720 million metric tons of above-ground carbon. Keeping this carbon locked in trees and soils helps prevent massive greenhouse gas emissions that would otherwise accelerate climate change.
Large forest systems are more resilient to drought, fire, and external pressures. When protected over time, they provide a form of climate security that smaller, fragmented forests cannot.

Life Needs Space
Wide-ranging species like jaguars depend on vast territories to hunt, reproduce, and maintain healthy populations. Their presence signals something deeper: a complete and functioning food web beneath them. From large herbivores like tapirs and peccaries to birds, fish, and countless smaller species, each layer of life depends on the others.
In fragmented forests, these relationships begin to break down. Species lose the ability to move, populations become isolated, and ecological balance is lost.
In Kayapo territory, the scale of the landscape allows life to move freely. Rivers like the Xingu and Iriri still run largely undisturbed, supporting rich aquatic ecosystems. Forests remain connected across vast distances, enabling species to roam, adapt, and thrive.
The rainforest creates its rain
Through evapotranspiration, trees release vast amounts of water vapor into the atmosphere, recycling moisture and feeding clouds. This process sustains rainfall locally and helps transport moisture deep into the continent through what we call “flying rivers.” These aerial flows carry water across thousands of kilometers, influencing rainfall patterns far beyond the forest itself.
Large, intact forests are essential to this system. When forests are fragmented or degraded, this moisture cycle weakens, with potential impacts on ecosystems and agriculture across South America.
As one of the largest intact forest blocks in the southeastern Amazon, Kayapo territory plays a critical role in maintaining this hydrological system. Its scale helps ensure that the forest continues to function as a living engine of water and climate.
