Like humans, peatlands need water to survive. When peatlands are drained, the compressed organic matter begins to decay, turning long-submerged carbon into carbon dioxide and adding more greenhouse gases to our already overheated atmosphere. Complicating matters, peatlands and all wetlands are natural sources of methane, a more potent but shorter-lived greenhouse gas. In some cases, draining may actually decrease methane emissions.

- This means if our peatlands are getting drier, we would have an increase in emissions of carbon dioxide, but a reduction in methane emissions.
- Complicating matters, peatlands and all wetlands are natural sources of methane, a more potent but shorter-lived greenhouse gas.Bulunamadı: increase
- 7. Peatland drainage leads to increase CO2 emissions, a rise of N2O release in nutrient rich peatlands but may not significantly reduce CH4 efflux.Bulunamadı: why
- When accounting for this higher GWP, increases in CH4 emissions may reduce or even counteract C savings associated with peatland restoration.
- CO2emissions from drained and burned peatlands equate to 10 per cent of all annual fossil fuel emissions. “These emissions can and should be avoided.
