Illustrative scenario
What if Colombian Amazon took a scaled approach to “Protected areas and Indigenous reserves”?
Starting point · documented
Forest clearing concentrated in an arc of deforestation threatens connectivity between the Andes and the Amazon.
The intervention · documented
Protected areas and Indigenous reserves
Expanding and enforcing protected areas and resguardos.
Indigenous lands and protected areas are associated with lower deforestation.
Schematic direction of change
Halting loss can happen faster than restoring what has been lost; ecosystems recover over years to decades.
Causes this could address
- Illicit cropsCoca cultivation contributes to clearing in some areas.
- Governance gapsWeak state presence in remote areas limits enforcement.
Impacts that could ease
- Biodiversity lossThe region is one of the most biodiverse on Earth.
- Loss of Andes–Amazon connectivityFragmentation disrupts ecological corridors.
Wider reach at higher intensity is an assumption of this illustration.
How change might unfold
Near term
Rates of clearing or degradation can slow where protection is enforced.
Medium term
Restored areas begin to function, supporting some species and services.
Long term
Mature habitat and biodiversity return slowly, and some losses are irreversible.
Faded stages are less likely to be reached at scaled intensity.
What this would not change
Extinctions cannot be reversed, and market, governance and climate pressures continue outside protected areas.
What it depends on
- Sustained funding and institutional capacity
- Consistent enforcement and monitoring
- Local stakeholder support
- Participation of affected communities
