Peatlands are wetlands where : a) waterlogging delays decay a) waterlogging delays decay ; b) dead plants form peat Colchis,Georgia What are peatlands What are peatlands
Lesotho Peat accumulates for thousands of years storing concentrated Carbon in thick layers peat from 2 m deep
Covering 4 million km 2, primarily in the boreal, subarctic and tropical zones, peatlands are found in almost every country. Peatlands are everywhere…

Peatlands are the most space-effective carbon (C) stocks of all terrestrial ecosystems. Kyrgystan Peatlands and carbon
While covering only 3% of the World’s land area, peatlands contain 550 Billion tonnes of carbon in their peat.
This is equivalent to twice the carbon stock in the forest biomass of the world.
This makes peatlands the top long-term carbon stock in the terrestrial biosphere. Ruoergai China
Peatland drainage and fires are one of the main sources of carbon released to the atmosphere from the land use sector.

Peat compared to other stores
The main impacts on peatlands include drainage for agriculture and forestry and associated peat fires, peat extraction, infrastructure and pollution
Drained peat releases carbon Drainage to 1 meter = emission of 90 ton CO 2 /ha/yr in tropics - 30 ton CO 2 /ha/yr in temperate regionDrainage to 1 meter = emission of 90 ton CO 2 /ha/yr in tropics - 30 ton CO 2 /ha/yr in temperate region SE Asia: Agriculture & agro-forestry on 12 million ha contributes around 600 MtCO 2 /yr (drainage only)
Main regions with peatland emisions from drainage
Burning peat releases more carbon Tentative average annual emissions estimate: 1400 to 4300 Mt CO 2 /y

Peatlands have greater potential for permanence than any other terrestrial ecosystem (All Coal and lignite and part of the oil and gas originated from peat deposits of previous geological periods).
Future trends in emissions
Water levels and methane emissions in temperate peatlands per year
Water levels and methane emissions in tropical peatlands per hour
Water levels and nitrous oxide emissions in tropical peatlands per hour
Emission reduction Stopping or controlling drainage and fire are the most important and cost effective measures to reduce peatland emissions. Stopping or controlling drainage and fire are the most important and cost effective measures to reduce peatland emissions. Increasing water levels in peatlands decreases Carbon dioxide and nitrous oxide emissions but may increases methane only in non-forested peatlands. The result is a net reduction in GHG emission. Increasing water levels in peatlands decreases Carbon dioxide and nitrous oxide emissions but may increases methane only in non-forested peatlands. The result is a net reduction in GHG emission. Pilot emission reduction projects have demonstrated that rapid reductions in emission can be achieved within months or at most a few years after the management interventions. Pilot emission reduction projects have demonstrated that rapid reductions in emission can be achieved within months or at most a few years after the management interventions. Large scale emission reductions are possible at relatively low cost of $1-5/tonne of Carbon dioxide. Large scale emission reductions are possible at relatively low cost of $1-5/tonne of Carbon dioxide. Emission reductions often have more permanence and less leakage that other land use emission reduction options.

Conclusions Peatlands are the most important terrestrial carbon store. Peatlands are the most important terrestrial carbon store. Peatland drainage and fire releases about 3 billion tonnes of Carbon dioxide per year – equivalent to about 40% of total emissions from land use change – equal to all emissions from deforestation – but on only 3% of the land area. Peatland drainage and fire releases about 3 billion tonnes of Carbon dioxide per year – equivalent to about 40% of total emissions from land use change – equal to all emissions from deforestation – but on only 3% of the land area. Peatland stocks naturally have a long permanence, but after degradation can generate long term emissions.

Drainage may reduce methane emissions in some peatlands but increases nitrous oxide emissions. Drainage may reduce methane emissions in some peatlands but increases nitrous oxide emissions.
