Climate Change

• A new study of Colombia’s lowland forests and savannas finds that the nation may have extensive peatlands — organic wetland soils formed over thousands of years — holding as much as 70 years’ worth of Colombia’s carbon emissions. Protecting them from agricultural development is essential to preventing greenhouse gas releases.
• Researchers made peatland estimates by taking sediment cores in 100 wetlands, quantifying peat content, then building a model to predict locales for other peat-forming wetlands using satellite imaging. Peat was found in unexpected ecosystems, such as nutrient-poor white-sand forests, widespread in northern South America.
• Sampling in many locations was only possible due to the ongoing but fragile peace process between the Colombian government and armed rebel groups. In some places, security has already deteriorated and further sampling is unsafe, making this study’s scientific estimate a unique snapshot for now.
• Most Colombian peatlands are remote, but deforestation is intensifying along the base of the Andes, putting some wetlands at risk. Colombia’s existing REDD+ projects have been controversial, but opportunities may exist to combine payments for ecosystem services with peacebuilding if governance and security can be improved.
