Why Peatlands Are Colombia’s Climate Insurance

Peatlands are often overlooked in global climate discussions. They are quiet landscapes, waterlogged soils, mosses, sedges, and cushion plants. Yet beneath their surface lies one of the largest carbon reservoirs on Earth.
Globally, peatlands cover only about 3% of the planet’s land surface, but they store approximately 450–600 gigatonnes (Pg) of carbon, which represents nearly one third of the world’s soil carbon stock.
Peatlands store more carbon than all the world’s forests combined, an extraordinary concentration of climate power in just 3% of the planet’s land surface.
The Science Behind Climate Insurance
Peat forms when plant production exceeds decomposition under saturated, low-oxygen conditions. In these environments:
Oxygen diffusion is limited
Microbial activity slows
Organic matter accumulates
Carbon is locked underground for millennia
In tropical peatlands, carbon accumulation rates range from 20 to over 100 grams of carbon per square meter per year, depending on hydrology and vegetation type.
In the Pastaza Marañón basin of the Peruvian Amazon alone, peat deposits up to 7.5 meters deep store approximately 3.1 gigatonnes of carbon in a relatively small region.
These numbers reveal a simple truth: Peatlands are long-term carbon sinks, but only while they remain wet.
When Peatlands Become Carbon Sources
The climate insurance analogy becomes clear when we examine disturbance.
When peatlands are drained for agriculture, grazing, or infrastructure:
The water table drops
Oxygen penetrates the soil
Peat oxidizes
CO₂ emissions increase dramatically
Although drained peatlands represent less than 0.5% of global land area, they contribute an estimated 5% of total anthropogenic CO₂ emissions from land use.
A single degraded hectare of peatland can emit as much carbon annually as several cars running continuously for decades.
Why Colombia Matters
Colombia holds approximately 2.8 million hectares of páramos, many of which contain peat-forming ecosystems. Beyond high elevations, peatlands are also present in Amazonian and transitional wetland regions.
Estimates suggest the country could host around six million hectares of peatlands, although mapping remains incomplete. Research in the Northern Andes identifies five major peat-forming vegetation types, from Sphagnum-dominated systems to cushion peatlands above 4,000 meters elevation. Sites affected by grazing or hydrological alteration show measurable declines in soil carbon.
This means peatlands are not only ecological features , they are strategic climate assets.
Protecting them strengthens:
National climate commitments.
Water regulation systems
Biodiversity resilience.
Long-term carbon stability
Climate Strategy, Not Just Conservation
In a warming world, preventing peatland degradation is often far more cost-effective than attempting to remove carbon through engineered solutions later. Conservation avoids emissions before they occur, rewetting reduces ongoing losses, and sustainable management safeguards long-term climate stability.
Peatlands are not peripheral ecosystems. They are climate infrastructure.
In the next article, we will examine how peatlands regulate water security in Colombia’s páramos and why millions depend on these systems without realizing it.

We are actively working to scale peatland restoration as a strategic climate solution.
Let’s build this together.
