🌍 What Are Peatlands?
Peatlands are powerful natural allies in the fight against the climate crisis, despite often being overlooked. Here's how they contribute:
Peatlands are wetlands with a thick waterlogged layer of partially decomposed plant material (peat), built up over thousands of years. They're found in many parts of the world, including boreal forests, tropical regions, and temperate zones.
✅ How Peatlands Help Fight Climate Change
1. Massive Carbon Storage
- Peatlands cover just 3% of the Earth's land surface but store over 600 billion tonnes of carbon—twice as much as all the world’s forests combined.
- By locking away CO₂, peatlands act as carbon sinks, keeping greenhouse gases out of the atmosphere.
2. Slow Decomposition
- The waterlogged conditions slow down microbial activity, preventing full decomposition of organic matter.
- This process locks carbon in the soil for thousands of years, unlike forests, which release CO₂ relatively quickly after tree death or decay.
3. Climate Regulation
- Healthy peatlands help regulate local and regional climates by maintaining moisture, humidity, and temperature balance.
⚠️ Threat: When Peatlands Are Damaged
If peatlands are drained, burned, or degraded (e.g., for agriculture, forestry, or development), they become major carbon sources:
- 1.9 gigatonnes of CO₂ are released annually from degraded peatlands (about 5% of global human emissions).
- Fires in peatlands (common in Southeast Asia) release massive emissions, cause haze, and destroy biodiversity.
💡 How to Use Peatlands in Climate Action
- Conservation of Intact Peatlands
- Preventing disturbance keeps their carbon locked away.
- Rewetting and Restoration
- Re-flooding drained peatlands stops emissions and begins the carbon-accumulation process again.
- Sustainable Use (Paludiculture)
- Cultivating wet-loving crops (like reeds or sphagnum moss) instead of draining peat for farming helps retain ecological functions.
🌱 In Summary
Peatlands = Carbon Banks.
Protecting and restoring them is one of the most cost-effective and immediate natural climate solutions available.
