Rewetting Peatlands: Reversing Climate Change Fast

Beneath the surface of Earth's marshes, bogs, and fens lies a secret carbon vault worth twice what all the world's forests hold combined. These waterlogged ecosystems—covering just 3% of land—have quietly sequestered a third of the planet's soil carbon over millennia. Yet we've been draining them for centuries, turning climate allies into carbon bombs. In 2015 alone, Indonesian peat fires released 1.6 gigatonnes of CO₂, matching Germany and France's annual emissions. Now scientists are racing to reverse the damage through a deceptively simple solution: letting water reclaim the land.

The paradox is striking. While reforestation captures headlines and billions in funding, peatlands store carbon for 10,000 years compared to forests' few centuries—yet receive a fraction of protection. Only 17% of global peatlands have any safeguards, while drained peatlands hemorrhage 2 billion tonnes of CO₂-equivalent annually, rivaling the emissions of 70 coal plants. But a growing movement of scientists, Indigenous communities, and forward-thinking farmers is proving that rewetting these forgotten landscapes can halt emissions within months and restore their carbon-sink function within a decade.

The Breakthrough: Reversing Centuries of Damage in Years

Peatlands function as nature's time capsules. In waterlogged conditions, dead plants decompose at glacial speed—building up organic matter at roughly one millimeter per year. This process, sustained over thousands of years, has locked away approximately 600 billion tonnes of carbon in peat soils worldwide. The mechanism is elegant: when saturated, oxygen-starved conditions prevent the microbes that normally break down organic matter from doing their work.

But drain a peatland, and the clock accelerates catastrophically. Exposed to air, peat oxidizes—essentially smoldering in slow motion. A single drained acre releases about 12 tonnes of CO₂ annually. In Germany's Mecklenburg-West Pomerania region, drained peatlands account for 40% of total greenhouse gas emissions despite covering far less land. The EU's drained peatlands emit 230 million tonnes of CO₂-equivalent yearly—15% of all global peatland emissions and roughly 7% of the bloc's total climate pollution.

Rewetting reverses this process by restoring the waterlogged conditions that built these carbon stores in the first place. The science is straightforward: block drainage ditches, remove pumps, rebuild natural water flow. Within months, the water table rises. Anaerobic conditions return. Oxidation slows, then stops. The peatland transitions from carbon source back to carbon sink.

Recent research quantifies the timeline. A decade-long study of China's Zoige alpine peatland found that blocking drainage ditches increased soil water content to 88.5% in hollows and 81.1% in hummocks—levels approaching or exceeding natural conditions. Groundwater levels rose by 119 millimeters within 10 meters of blocked ditches in the first year alone. Perhaps most crucially, rewetted sites in horticultural peat extraction trials achieved net CO₂ uptake rates matching pristine peatlands within 14 years, though with greater year-to-year variability.

The implications are profound. Unlike tree-planting schemes that take decades to sequester meaningful carbon, rewetting delivers immediate emission reductions. North Carolina's restoration of 43,000 acres of pocosins—shrub-dominated peatlands—has already prevented catastrophic wildfires and could avoid 4.3 million tonnes of CO₂ emissions if scaled to 200,000 acres. That's equivalent to removing nearly a million cars from the road permanently.

Historical Perspective: From Carbon Vaults to Climate Liabilities

Humanity has been draining peatlands for agriculture and fuel for centuries, but the scale accelerated dramatically in the 20th century. In Europe, drainage began 200-300 years ago; in Southeast Asia, the process intensified only 50-60 years ago, yet with devastating speed. Indonesia, home to 24 million hectares—36% of the world's tropical peatlands—saw massive conversion to palm oil plantations and timber concessions. When those dried peats caught fire in 2015, over half a million people were hospitalized for respiratory infections, and the Indonesian economy suffered an estimated $16 billion in damages.

The pattern repeated globally. In the United States, approximately 4% of peatlands have been destroyed since colonial times, with degraded peatlands now emitting 47 million metric tons of CO₂-equivalent annually—comparable to 11 million gasoline vehicles driven for a year. Minnesota's 6 million acres of peatlands store an estimated 4 billion metric tonnes of carbon, equivalent to 27 years of the state's annual emissions, yet many remain at risk.

Finland offers a cautionary tale of unintended consequences. The country's forests and peatlands historically functioned as a massive carbon sink. But aggressive forestry practices and peatland drainage have reversed this. From 2009 to 2022, Finland's forest land sink declined by roughly 90%, with soil and peat emissions surging. By 2021-22, the country's land sector had become a net carbon source—a climate tipping point with global implications.

The lesson from history is clear: technological advances that once seemed like progress—drainage systems, industrial agriculture, peat extraction—can trigger feedback loops that accelerate climate change. But history also shows that course corrections are possible. Russia has restored over 35,000 hectares of drained peatlands using ecological methods. Scotland's Peatland ACTION programme has already restored more than 10,000 hectares, with plans for 70,000 by decade's end. The question isn't whether rewetting works, but whether we'll scale it fast enough.

The Technology Explained: Engineering Water Back into the Landscape

Rewetting peatlands requires more than simply filling in ditches. Success demands precision hydrological engineering tailored to each site's unique characteristics: peat depth, vegetation type, drainage history, and surrounding land use.

Ditch Blocking and Dam Construction

The foundational technique involves constructing barriers in drainage channels to prevent water from flowing away. Peat dams—built from unoxidized peat extracted on-site—are highly stable, impermeable, and resistant to erosion. In Sweden's Trollberget Experimental Area, researchers blocked 59% of ditches in one catchment and just 16% in another. The more thoroughly blocked site showed significant reductions in peak flow and runoff during extreme rainfall events, demonstrating that partial measures deliver partial results.

Log dams built at intervals create a cascading series of water-holding ponds. Some projects use biodegradable timber blocks instead of plastic to stabilize vegetation, eliminating long-term environmental risks. Temporary structures serve as stopgaps while natural processes reestablish equilibrium.

Groundwater Table Management

Raising the water table is the critical metric. Research shows that peatlands function as optimal carbon sinks when the average seasonal water table sits within 25 centimeters of the surface and plant cover exceeds 100% (combining moss and vascular layers). But achieving this consistently requires careful monitoring.

Modern projects deploy networks of dipwell sensors that measure groundwater levels at hourly intervals. Machine-learning algorithms analyze this data alongside soil moisture readings, weather patterns, and topographic data to predict water table fluctuations and guide intervention strategies. One study used the Simulation of Groundwater (SIMGRO) model to estimate water table depth based on terrain characteristics, peat thickness, and climate variables—providing the quantitative basis for carbon credit certification.

Vegetation Management

Water alone isn't sufficient. Rewetted sites require appropriate vegetation to rebuild peat. The Moss Layer Transfer Technique (MLTT) involves transplanting intact moss layers from healthy sites to restored areas. This approach has proven the fastest and most consistent strategy for returning optimal moisture conditions and vegetation cover.

Native species like Sphagnum mosses are essential—they thrive in waterlogged acidic conditions and their decay-resistant structure forms the building blocks of peat. However, studies show that even with rewetting and revegetation, plant community composition may differ from pristine sites for decades. In China's Zoige peatland, rewetted areas showed higher aboveground biomass but lower belowground biomass than natural peatlands, indicating a shift in carbon allocation that could affect long-term peat accumulation.

Remote Sensing and Monitoring

The scale of needed restoration—millions of hectares globally—demands efficient monitoring. Satellite remote sensing has revolutionized peatland science. The Optical Trapezoid Model (OPTRAM), using Sentinel-2 imagery, can monitor water tables weekly across diverse sites. Cloud-penetrating L-band Synthetic Aperture Radar (SAR) systems deliver consistent surface moisture estimates even in perpetually cloudy tropical peatlands, removing a longstanding observational barrier.

LiDAR provides high-resolution topographic data crucial for identifying microtopography—the hummocks and hollows that structure peatland ecosystems and influence drainage patterns. Integrating optical, radar, and LiDAR data with machine learning dramatically reduces the need for extensive ground validation, making large-scale monitoring scalable and cost-effective.

Reshaping Society: Industries and Livelihoods in Transition

Rewetting peatlands doesn't just alter landscapes—it fundamentally reshapes the economic and social systems built on drained land. In Germany, where roughly 5,000 acres are rewetted annually against a target of 100,000, the tension between climate goals and agricultural livelihoods creates political deadlock. Farmer Jörg Espig, whose family has worked drained peatlands for generations, captures the dilemma: "If that dike weren't there, this area would be covered with water." For him, dry fields mean viable livestock farming; for conservationists, those same fields represent 12 tonnes of CO₂ per acre annually.

This stakeholder conflict appears worldwide. In Indonesia, the Peatland Restoration Agency (BRG) claims to have "restored" 3.66 million hectares by raising groundwater levels to at least 40 centimeters below the surface. Yet fewer than 6,000 hectares received vegetation rehabilitation, and water table data shows wild swings—from 3.5 million hectares meeting the 40-centimeter threshold in wet 2019 to just 0.5 million in dry 2022. Critics argue that rewetting without vegetation reestablishment leaves peatlands vulnerable to fire and fails to restore ecological function.

Paludiculture: The Economic Bridge

Enter paludiculture—the productive use of wet peatlands that maintains the peat body and ecosystem services while generating income. The term, coined by Hans Joosten in 1998, describes cultivating commercially valuable crops on rewetted or naturally wet peatlands: reed, cattail, peatmoss, sago palm, and various grasses.

In Indonesia, communities are weaving purun grass into mats and baskets—a traditional craft now integrated into restoration economics. Akhmad Baihaki, a 21-year-old artisan from Pulantani village, received training in business development of purun craft through UNOPS-supported programs. This model demonstrates how rewetting can empower local communities rather than displacing them.

Ireland's €10 million Palus Demos project, led by the University of Galway with 26 European partners, aims to develop markets for paludiculture products. Early projections suggest paludiculture could boost farmers' incomes to €33,000 per hectare annually, with additional revenue from carbon credits. "It's not about preaching to farmers about the environment," explains project leader Niall Ó Brolcháin, "but providing a positive alternative."

Research confirms paludiculture's climate benefits. Studies show that while rewetting can temporarily increase methane emissions in some systems (especially with species like reed canary grass and papyrus), the long-term net greenhouse gas balance remains strongly positive because halted CO₂ emissions far outweigh methane increases. The key is matching crop selection to site hydrology and carefully managing water levels.

Job Market Transformations

The restoration economy is emerging. Scotland's £250 million Peatland ACTION program has created specialized contracting firms equipped with low-pressure machines designed for moorland topography. The South West Peatland Partnership aims to restore hundreds of hectares yearly across Dartmoor, Exmoor, and Cornwall, employing contractors through autumn and winter—seasons chosen to protect nesting birds and optimize peatland hydrology.

Yet capacity constraints threaten scaling. A ClimateXChange study analyzing 158 Scottish restoration projects found that lack of standardized cost reporting and complex tendering processes create uncertainty for contractors, reducing competition and inflating unit costs. Median restoration costs hit £1,025 per hectare with a standard deviation of £4,328—enormous variability driven by site remoteness, peat condition, and project size. Simplifying tendering procedures and providing long-term funding commitments could encourage investment in restoration capacity.

Cultural Shifts and Community Resilience

In Finland's Lapland, climate-induced drying threatens reindeer herding—a cornerstone of Sami culture—as mushrooms that reindeer feed on become scarce. "The Boreal forests here take so long to grow that even small, stunted trees are often hundreds of years old," explains Tiina Sanila-Aikio, former president of the Finnish Sami parliament. Peatland restoration isn't just about carbon; it's about preserving ways of life adapted over millennia.

Ireland's Connecting Communities with Peatlands (CCWP) project, funded through the Just Transition Fund from 2021-2024, delivered peer-led mentoring for seven community groups and 22 training courses covering conflict resolution, Leave No Trace awareness, design thinking, and plant identification. Youth camps transformed perceptions, fostering long-term stewardship. One participant noted, "We don't ignore the fact that a big part of the success is community engagement and participation."

The Promise: Climate, Biodiversity, and Beyond

The climate math is compelling. Rewetting Europe's degraded peatlands could eliminate emissions equivalent to 32 million tonnes of CO₂ annually by 2030—the EU's Land Use, Land Use Change and Forestry (LULUCF) regulation target. Globally, drained peatlands contribute roughly 5% of anthropogenic greenhouse gas emissions, more than aviation and shipping combined. The World Resources Institute estimates that drainage in Indonesia and Malaysia alone produces annual emissions equal to nearly 70 coal plants.

But rewetting delivers far more than carbon mitigation:

Water Regulation: Peatlands absorb 100-1,300% of their dry weight in water, compared to 20-30% for mineral soils. This extraordinary capacity buffers floods during heavy rainfall and sustains flow during droughts. The Trollberget study demonstrated that rewetting significantly decreased peak flow and reduced hydrograph flashiness, making restored sites function like pristine peatlands during extreme rainfall.

Biodiversity Havens: Peatlands host species found nowhere else—insectivorous sundews, rare orchids, curlews, hen harriers, bog bush crickets. Scotland's Scaliscro restoration project supports Atlantic salmon, recently listed as endangered on the IUCN Red List. In Snowdonia, a rewetted upland farm saw the return of rare bird species after two decades. Indonesia's Katingan Mentaya Project protects over 5% of the global Bornean orangutan population across 149,800 hectares of peat swamp forest.

Fire Prevention: Dried peat is essentially pre-packaged fuel. Russian peatland fires have released as much carbon in a few months as total annual human CO₂ emissions. North Carolina's pocosin restoration explicitly targets wildfire risk reduction—a co-benefit valued by insurance companies and emergency managers.

Economic Services: Minnesota's Sax-Zim Bog generates $1.18 million annually in bird-watching tourism. Restored peatlands improve water quality downstream, reducing treatment costs. In the UK, research estimates that restoring 20% of Scotland's peatlands would yield economic benefits of £80-336 million per year.

Historical Archives: Healthy peat preserves a record of human-environment interactions dating back thousands of years. "If we let the peat dry out or erode away, we risk losing that information," warns Martin Gillard, the South West Peatland Partnership's historic environment officer. Bog bodies, ancient pollen, and chemical signatures locked in peat layers provide irreplaceable climate data and archaeological insights.

The Dark Side: Challenges, Conflicts, and Unintended Consequences

Despite the promise, rewetting faces formidable obstacles:

Methane Paradox: While rewetting halts massive CO₂ emissions, it can temporarily spike methane production—a greenhouse gas 28 times more potent than CO₂ over a century. The net climate benefit remains strongly positive, but methane dynamics complicate carbon accounting and require careful monitoring. Models that use daily time steps may underestimate methane ebullition (bubble release), which occurs at sub-daily scales. High-resolution process-based models running at half-hourly intervals are necessary to capture these dynamics accurately.

Incomplete Recovery: Even after 70 years of rewetting, only 13-21% of original soil organic matter remains as resistant organic material. The most labile carbon is lost within the first few decades of drainage—emissions that cannot be fully reversed. Restored peatlands show greater interannual variability in CO₂ uptake than pristine sites, and during dry years can temporarily switch back to carbon sources. Climate change exacerbates this: a 1°C temperature rise decreases annual CO₂ uptake by approximately 5%; a 2°C rise, by 16%.

Land Use Conflicts: Rewetting requires land currently used for agriculture, forestry, or peat extraction. Finland's finance ministry estimates that reducing forest harvest by one-third to protect peatlands would cost the economy €1.7-5.8 billion annually—a 2.1% GDP reduction. Such trade-offs create fierce political resistance. Rapid approval processes and financial incentives for farmers are essential but politically challenging to implement.

Water Scarcity Tensions: In regions where groundwater extraction for drinking water or irrigation contributes to peatland drying, rewetting competes with other water uses. Balancing these demands requires integrated watershed management and stakeholder negotiation—processes that can take years.

Displacement and Leakage: If rewetting forces agricultural production to shift elsewhere, the carbon benefit diminishes. The Scaliscro project in Scotland includes a 15% buffer zone specifically to detect and mitigate such leakage, but monitoring displacement at scale remains challenging.

Permafrost Time Bombs: Northern peatlands hold up to 39 billion tonnes of carbon—twice that stored in all European forests. Climate models show that even with strong emission reductions, Northern European climates will no longer sustain peat permafrost by 2040. Once thawed, permafrost peat degrades as rapidly as active-layer peat, with laboratory studies showing cumulative CO₂ production reaching 67-125% of surface peat levels within a year. Thermokarst pond formation following peat plateau collapse can accelerate methane production to 38.6% of CO₂ accumulation. Rewetting strategies developed for temperate peatlands may not translate to these rapidly thawing systems.

Policy Fragmentation: Despite growing awareness, policy remains fractured. The EU's Common Agricultural Policy (CAP) fails to formally recognize paludiculture as eligible agricultural activity, blocking farmers from accessing incentive payments. The UK's Peatland Code, launched in 2015 as a voluntary carbon market standard, has enabled some projects but lacks the scale needed for national impact. Verra's Methodology VM0027 for tropical peatland rewetting was inactivated in 2023 after no projects registered within five years—a regulatory bottleneck signaling insufficient incentive structures.

Global Perspectives: From Indigenous Stewardship to Corporate Greenwashing

Peatland restoration is unfolding unevenly across continents, shaped by culture, governance, and economics:

Indigenous Leadership: At least 27% of global peatlands—covering 1.1 million square kilometers—overlap with Indigenous territories. More than 85% of peatlands within Indigenous lands lack other forms of protected area designation, yet these communities have safeguarded them for millennia. "Peatlands have been protected by Indigenous Peoples since time immemorial and continue to be," states the Can-Peat project. Strengthening Indigenous land rights emerges as a powerful, cost-effective conservation strategy. In Colombia, researchers estimated that peatlands hold 1.9 billion metric tons of carbon—equivalent to 70 years of the country's fossil fuel emissions—much of it on Indigenous lands.

European Policy Innovation: The EU's Nature Restoration Law, adopted in June 2024, sets legally binding targets for peatland restoration: 30% by 2030, 60% by 2040, 90% by 2050. Crucially, it mandates rewetting as a prerequisite, not an optional add-on. Germany, despite political challenges, has established ambitious targets: 100,000 acres rewetted annually to achieve climate neutrality by 2050. Yet actual progress lags at about 5,000 acres per year—a 95% shortfall requiring urgent policy acceleration.

UK Carbon Markets: The UK Peatland Code creates a domestic voluntary carbon market for restoration projects. Landowners can sell Pending Issuance Units (PIUs) that convert to Peatland Carbon Units after five-year verification. The Scottish government has earmarked £250 million for restoration through 2030 under the Peatland ACTION programme. Three educational leaflets produced with the IUCN UK Peatland Programme help landowners understand how to create Peatland Code projects and access private finance—demonstrating how targeted outreach can unlock participation.

Ireland's Certification Breakthrough: In 2025, Ireland launched a new Peatland Standard aligned with the EU Carbon Removals and Carbon Farming Certification Framework. This scientifically grounded methodology quantifies not just carbon sequestration but also volumetric water benefits, biodiversity improvements, water quality enhancement, wildfire risk reduction, and flood mitigation. Independent third-party auditors validate claims according to ISO standards. Landowners adopting the Standard can access funding from businesses committed to environmental conservation, creating a market-based incentive structure.

Asia's Scale and Struggle: Indonesia's experience illustrates the gap between policy ambition and implementation. The BRG's target of 2.6 million hectares restoration focused heavily on raising water tables but largely neglected vegetation rehabilitation—the essential second step. As David Taylor from the National University of Singapore noted, "Rewetting should be seen as a first step, not the finish line." Without native plants, rewetted peatlands remain fire-prone and ecologically incomplete. The 2015 fires that hospitalized half a million people and cost $16 billion demonstrate the stakes of incomplete restoration.

Corporate Finance Models: Rewilding Europe's Rewilding Climate Solutions platform, supported by a €2 million Grantham Foundation grant, aims to make peatland rewilding commercially attractive through nature-based carbon credits. Phase I evaluated 10 potential sites, narrowing to the Oder Delta and Swedish Lapland as pilots. Phase III plans to raise €10 million+ for large-scale restoration. "We want to make peatland rewilding initiatives commercially attractive, which will unlock a lot more funding on an ongoing basis," explains Timon Rutten, Head of Enterprise. This blended private-public finance model—combining public grants, carbon credit sales, and philanthropic capital—may offer the most promising route for scaling restoration beyond what government budgets alone can achieve.

Capacity Constraints: The biggest bottleneck isn't money—it's expertise. Large-scale landscape restoration requires specialized knowledge: hydrology, soil science, ecology, engineering, community engagement. Training programs remain inadequate. Contractor capacity lags demand. Political uncertainty creates a "valley of death" between feasibility studies and project maturity, deterring private investment. Ireland's CCWP project's focus on peer-led training and youth engagement represents an attempt to build the human infrastructure restoration requires.

Preparing for the Future: Skills, Policies, and Personal Action

As rewetting scales from niche conservation projects to mainstream climate strategy, new skills and systems will become essential:

Professional Opportunities: Restoration ecology is emerging as a career field. Specialized contractors command premium rates for peatland work—operating low-pressure machinery on sensitive moorlands, designing bespoke dam systems, conducting post-restoration monitoring. Remote sensing analysts who can process satellite data to map peat extent and water tables are increasingly valuable. Carbon credit verifiers and auditors who understand peatland-specific methodologies will be needed as voluntary markets mature.

Policy Skills: Peatland restoration requires navigating complex regulatory landscapes—agricultural policy, water rights, carbon accounting frameworks, biodiversity law. Advocates who can translate scientific findings into legislative language, negotiate stakeholder conflicts, and design incentive mechanisms will shape whether restoration reaches the necessary scale. Understanding the nuances of the EU's CAP reform, the UK's Peatland Code, or Indonesia's BRG mandate is becoming as important as understanding peat hydrology.

Community Engagement: The CCWP project's emphasis on conflict resolution, design thinking, and cultural heritage points toward the soft skills restoration demands. Top-down restoration imposed on communities often fails; co-designed projects that integrate local knowledge and create shared benefits succeed. Learning to facilitate these processes—honoring Indigenous stewardship, supporting craft-based livelihoods like purun weaving, or organizing youth camps that build long-term investment—may be as crucial as technical expertise.

Financial Innovation: Blended finance models combining public grants, private carbon credit sales, and philanthropic capital require new forms of partnership. Understanding how to structure deals that satisfy regulatory requirements while delivering returns attractive to corporate investors demands bridging traditionally separate worlds. The €2 million Grantham grant to Rewilding Europe exemplifies how strategic early-stage capital can catalyze much larger private flows.

Personal Adaptation: For those living near peatlands, adaptation may mean rethinking land use. Farmers might transition to paludiculture crops, learning to cultivate reed or cattail instead of wheat or livestock. Homeowners in peatland regions should understand flood risk implications—rewetting upstream can alter downstream hydrology. Supporting local restoration projects, whether through volunteer labor, advocacy, or financial contributions, creates tangible impact.

Consumer Choices: Avoiding peat-based horticultural products (common in garden centers) reduces extraction pressure. Choosing sustainably sourced palm oil, if available, indirectly protects Indonesian peatlands. Investing in or purchasing carbon credits from certified peatland restoration projects channels private capital where it's needed. These individual actions, while modest, aggregate into market signals that shift corporate behavior.

The Path Forward: Turning Climate Guardians Back On

Peatlands represent one of the few climate solutions that delivers immediate emission reductions while simultaneously building long-term carbon storage. Unlike carbon capture technology that remains experimental and expensive, or tree-planting that takes decades to sequester significant carbon, rewetting works on human timescales and leverages processes nature perfected over millennia.

The mathematics is unambiguous. With drained peatlands contributing 2 billion tonnes of CO₂-equivalent annually—roughly 5% of anthropogenic emissions—and covering just 3% of land, they punch far above their weight in both problem and solution space. Rewetting 500,000 hectares annually in the EU and 2 million hectares globally, as experts recommend, could eliminate emissions equivalent to shutting down dozens of coal plants while simultaneously enhancing water security, protecting biodiversity, and creating green jobs.

Yet the path forward requires confronting hard truths. The first decades after drainage are the most carbon-dynamic—losses incurred then cannot be fully reversed. Climate change itself threatens to undermine restoration, turning carefully rewetted sites back into sources during extreme droughts or thawing permafrost zones that release carbon faster than rewetting can sequester it. The window for action narrows each year permafrost continues warming and tropical peatlands continue burning.

Success hinges on moving beyond pilot projects to systemic transformation. That means binding policy frameworks like the EU Nature Restoration Law, with enforcement mechanisms and adequate funding; reformed agricultural subsidies that recognize paludiculture as eligible activity and reward farmers for water stewardship; streamlined regulations that reduce tendering complexity and encourage contractor investment; mandatory carbon accounting that includes peatlands in national greenhouse gas inventories and climate models; Indigenous rights recognition that formalizes co-management arrangements and supports traditional stewardship; blended finance mechanisms that de-risk private investment while maintaining environmental integrity; and capacity building that trains the workforce restoration demands at scale.

The technology exists. The science is proven. The co-benefits are documented. What remains uncertain is political will—whether societies will prioritize long-term climate stability over short-term economic continuity.

There's a deeper question here about how we understand progress. For centuries, draining peatlands represented advancement—turning "wasteland" into productive farmland. Now we recognize that productivity measured purely in crop yields or timber volume misses the value of carbon storage, water regulation, and biodiversity. Rewetting forces a reckoning with that narrow definition of progress and asks whether we can embrace restoration as a higher form of development.

The answer will shape more than peatlands. It will reveal whether humanity can intentionally reverse industrial-era damage at the scale and speed climate stability requires. Peatlands are a test case—contained enough to be manageable, important enough to matter, simple enough in principle (block drains, add water) that failure can't be blamed on technological inadequacy.

The clock is running. Permafrost peatlands approach tipping points within decades. Tropical peat fires grow more frequent and severe. Each tonne of CO₂ released from drained peat is carbon that took millennia to sequester and seconds to lose. But unlike many climate challenges, this one has a clear solution: let water reclaim the land, work with communities rather than against them, and give nature's carbon vaults the chance to do what they've done for 10,000 years—turn atmospheric carbon into solid ground beneath our feet. The only question left is whether we'll act while there's still time to turn back the clock.
