A new satellite analysis shows agriculture is the primary driver of tropical peatland conversion in Indonesia, Peru, and the Democratic Republic of Congo (DRC). This conversion, which includes burning for clearance, releases substantial greenhouse gases, undermining the carbon storage of these vital ecosystems. The study provides a detailed breakdown of emissions sources across the three countries.
Facts First
- Agriculture is the leading cause of peatland loss in Indonesia, Peru, and the Democratic Republic of Congo (DRC)
- Smallholder agriculture dominates conversion in Peru and the DRC, accounting for over 90% of emissions in the DRC
- Burning for clearance contributes roughly half of the total greenhouse gas emissions from peatland conversion
- Logging, mining, and road development are also significant drivers of loss in Indonesia and Peru
- Large-scale agriculture played no significant role in peatland conversion in the DRC
What Happened
A recent study analyzed satellite imagery to quantify the drivers and greenhouse gas emissions from tropical peatland conversion in Indonesia, Peru, and the Democratic Republic of Congo (DRC). Agriculture was identified as the primary driver of loss across all three countries. In Indonesia, agriculture accounted for 67% of peatland conversion and was the leading source of emissions. In Peru, smallholder agriculture was responsible for 61% of agricultural conversion. In the DRC, smallholder agriculture accounted for 93% of peatland conversion and 94% of emissions. Logging was a key driver in all three countries, while mining and road development were major factors in Indonesia and Peru. The study found that burning accounted for approximately half of the total greenhouse gas emissions resulting from conversion.
Why this Matters to You
The conversion of these peatlands directly impacts global climate stability. Peatlands cover less than 3% of the world's landmass but sequester more carbon than any other terrestrial ecosystem. Their deforestation and drainage release stored greenhouse gases, contributing to climate warming that may affect weather patterns, agricultural yields, and long-term environmental security worldwide. The detailed mapping of emissions sources could help focus conservation efforts more effectively.
What's Next
The study's findings provide a clear, data-driven picture of the primary pressures on these critical carbon stores. This information could be used by governments and conservation organizations to target policies and interventions, potentially focusing support for sustainable smallholder agriculture practices in Peru and the DRC. Further monitoring using similar satellite analysis methods is likely to continue tracking the fate of these ecosystems.
