But centuries of drainage, agriculture, and extraction have dramatically altered these ecosystems. Today, half of Europe’s wetlands are gone, and the loss is not only cultural or ecological: wetlands are among nature’s most powerful carbon sinks. When they are disturbed, however, they can flip from storing carbon to releasing greenhouse gases.

A new study published in Nature addresses a major obstacle to climate-aware restoration policy: the absence of a continent-wide, high-resolution picture of where wetlands are, what types they are, and how disturbed they have become. Led by researchers at the Global Wetland Center at the University of Copenhagen, the work aims to make wetland restoration targets measurable and actionable across Europe.

“To meet wetland restoration targets, we need a high-resolution map showing their extent, the different types, and what is disturbing them today,” says lead author Gyula Máté Kovács. He emphasizes that without such insight, it is difficult to assess wetlands’ true climate impact—especially where restoration potential is greatest.

Using 10-meter satellite imagery and machine learning, the team produced an open-access digital product called European Wetland Types. The map classifies six categories of natural and semi-natural wetlands across 38 European countries, enabling consistent, cross-border comparisons of wetland extent and condition.

The researchers highlight that Europe’s wetlands are highly fragmented. Roughly 27–33% occur in contiguous areas smaller than 25 hectares, and 7–11% are found in patches under 1 hectare. Because many existing datasets are too coarse, the smallest wetlands may be systematically missed—reducing the accuracy of restoration planning and carbon risk assessments.

Across the mapped region, about one fifth of wetlands are highly affected by human activity. Inland marshes emerge as among the most disturbed, while peatlands are flagged as a top priority for climate benefits due to their strong capacity to store soil carbon.

However, the stakes extend beyond biodiversity. The study estimates that up to five billion tonnes of CO₂-equivalent soil carbon may have been released compared with a scenario where these wetlands remained undisturbed—an amount comparable to roughly 1.5 years of total EU CO₂ emissions.

Built to support implementation of the EU Nature Restoration Law, the map helps member states identify restoration candidates and estimate likely climate outcomes. By harmonizing how wetlands are defined across countries, it also allows EU institutions to evaluate reporting on a comparable basis.

The team is now extending the approach to develop a global version of the map, with the goal of improving worldwide estimates of greenhouse gas emissions from wetlands and guiding restoration strategies at larger scales.

]]> 172824 Sister Projects Urge Stronger EU Measures to Save Europe’s Wetlands https://scienmag.com/sister-projects-urge-stronger-eu-measures-to-save-europes-wetlands/ Wed, 08 Jul 2026 20:38:16 +0000 https://scienmag.com/sister-projects-urge-stronger-eu-measures-to-save-europes-wetlands/ A coalition of Europe’s leading wetland restoration projects has released a pivotal white paper urging immediate, unified policy action to protect and rehabilitate these critical ecosystems. The joint effort, involving major EU-funded initiatives such as ALFAWetlands, RESTORE4Cs, REWET, and WET HORIZONS along with other key partners, draws on extensive scientific research, policy analysis, and extensive field experience to recommend a comprehensive strategy for wetland conservation across Europe.

Wetlands are among the continent’s most vital ecological resources, serving as natural water filters, flood regulators, carbon sinks, and biodiversity hotspots while supporting local economies and communities. However, ongoing drainage, reclamation, and land-use transformations compounded by climate change are causing rapid wetland degradation. This not only threatens biodiversity but also undermines the role of wetlands as carbon storage systems, thereby conflicting with the European Union’s climate commitments.

The white paper lays out four critical strategic priorities to drive policy reform. These emphasize harmonizing European environmental policies, mobilizing funding from both public and private sectors, enabling landscape-scale restoration efforts through improved governance, and enhancing wetland monitoring coupled with active stakeholder engagement. These priorities are informed by evidence collated across diverse ecosystems and political contexts, reflecting a consensus on the pathways necessary to overcome existing barriers.

European policy instruments such as the Nature Restoration Regulation, Water Framework Directive, Common Agricultural Policy, and LULUCF Regulation are identified as crucial levers to expedite wetland recovery. Furthermore, emerging frameworks like the EU Carbon Removals and Carbon Farming Regulation and the international Kunming–Montreal Global Biodiversity Framework offer new opportunities to integrate wetland restoration into broader climate and biodiversity agendas.

Practical examples underscore the feasibility and benefits of coordinated action. Finland’s success in restoring thousands of hectares of peatlands through national programs and innovative financing mechanisms highlights the effectiveness of voluntary landowner participation combined with policy support. Germany’s experience showcases how participatory governance coupled with sustainable bioeconomy value chains can ensure restoration efforts are economically sustainable. In Spain, tailored approaches respecting hydrological complexities and rigorous monitoring demonstrate the importance of science-backed strategies.

Despite geographical and contextual differences, a striking convergence emerges among these projects regarding priority actions and solutions. This alignment reinforces the call for decisive, cohesive efforts by EU institutions, national authorities, and local stakeholders to realize the full potential of Europe’s wetlands in climate resilience and socio-economic sustainability.

The coalition emphasizes that wetland restoration transcends environmental considerations; it represents a strategic investment in water security, climate adaptation, and long-term regional well-being. They urge policymakers to transform the current political will and momentum into effective, on-the-ground implementation before the narrow opportunity window closes.

This united call signals a critical moment for Europe’s wetlands—ecosystems essential not only for their environmental functions but also for the future prosperity and resilience of European societies confronting the escalating challenges of climate change.
