Key Details
UNEP’s Peatlands Matter synthesises evidence on peatland conservation, restoration, livelihoods and climate policy. Its findings extend beyond carbon: healthy peatlands also regulate water, limit flooding, support biodiversity and sustain local communities.
Area | Key Finding |
|---|---|
Global significance | Peatlands cover about 3% of global land but hold one-third of global soil carbon. |
Scale of degradation | Nearly 12% of peatlands—around 59 million hectares—are so degraded that peat formation has ceased. |
Restoration impact | Rewetting drained peatlands can reduce carbon dioxide emissions by 50–75% compared with drained conditions. |
Climate-policy pathway | Countries should incorporate peatland protection and measurable rewetting targets into NDCs, adaptation plans and biodiversity strategies. |
Himalayan evidence gap | The review found only three Hindu Kush Himalayan restoration studies, all conducted between 2011 and 2015 by a single research group. |
What Is a Peatland?
A peatland is an ecosystem in which waterlogged conditions slow the decomposition of plants, allowing partially decayed organic matter — peat — to accumulate. Draining it introduces oxygen, accelerating decomposition and releasing stored carbon.
Protecting Intact Peatlands Offers the Strongest Return
Wet, undisturbed peatlands generally have the lowest greenhouse-gas emissions, whereas drainage exposes stored organic matter to decomposition and releases carbon accumulated over centuries or millennia. Drained landscapes also become more vulnerable to fire, erosion, subsidence and declining water quality.
The report consequently places protection ahead of repair. Avoiding drainage and degradation is usually cheaper and more reliable than attempting to recreate peat-forming conditions after hydrology and vegetation have been altered.
Where damage has occurred, restoration should begin by stabilising water levels and rewetting the peat, accompanied where necessary by native vegetation recovery, fire prevention and restrictions on damaging land uses.
Rewetting Produces a Net Climate Benefit
Rewetting can initially increase methane emissions as waterlogged conditions return. The report finds that this does not normally cancel the larger benefit from sharply lower carbon dioxide emissions: most restored peatlands achieve a net climate benefit within approximately five years.
Effective projects nevertheless require long-term monitoring, including water levels, vegetation, greenhouse-gas flows and whether restored sites resume accumulating peat. Short project cycles may capture initial ecological changes without establishing whether recovery will endure.
India’s Himalayan Peatlands Face an Evidence Deficit
The assessment covers mountain peatlands in both the Andes and the Hindu Kush Himalaya (HKH) and includes Indian examples near Chandertal and Miyar Valley. These high-altitude wetlands can support biodiversity, regulate water flows and provide grazing resources, but they remain poorly recognised and studied.
The evidence imbalance is striking: the review identified three HKH studies compared with a much larger body of Andean research, and monitoring in the Himalayan studies did not extend beyond three years. This limits confidence in applying restoration practices developed elsewhere to Indian conditions.
For India, the immediate requirement is therefore not simply to reproduce international restoration models. It is to establish site-specific evidence on peat distribution, hydrology, carbon storage, grazing pressures and restoration outcomes across Himalayan landscapes.
Conservation Must Also Work for Local Communities
The report cautions against treating peatlands solely as carbon assets. Conservation can fail when it restricts livelihoods without providing viable alternatives or ignores customary rights and local knowledge.
Possible livelihood pathways include paludiculture—productive use of wet peatlands without drainage—along with sustainable fisheries, grazing, agroforestry and non-timber products. Their viability depends on local ecology, markets and community participation rather than a single universal model.
It also recommends secure tenure, free, prior and informed consent, and meaningful participation by Indigenous Peoples, local communities, women and young people when peatland policies or carbon projects affect their land and livelihoods.
Policy Relevance
For India, the report points towards a protect-first Himalayan strategy:
Build the evidence base: Identify and map peatlands within wetland, alpine and high-altitude landscape inventories, including their condition, hydrology and carbon stocks.
Protect sites before restoration becomes necessary: Road construction, tourism, drainage and poorly managed grazing should be assessed for their effects on peat-forming systems, not only on visible vegetation or water bodies.
Connect peatlands with climate planning: Verified peatland measures could eventually support India’s NDC, National Biodiversity Strategy and Action Plan, adaptation planning and land-restoration commitments.
Test restoration locally: Hydrological interventions and grazing controls should use Indian reference sites, native species and sufficiently long monitoring periods.
Keep communities at the centre: Pastoral and local knowledge should inform management, while conservation measures must account for access, livelihoods and customary use.
Avoid premature carbon claims: Carbon finance may help fund protection, but credible accounting, permanence safeguards and community benefit-sharing must precede market-based projects.
