Denmark’s greener land plans depend on agreements with owners

Across Denmark, local groups have mapped possible wetlands, forests and changes to farmland. Making those plans work now means reaching agreements with owners, finding skilled staff and following what happens to the land and water.

A field near a watercourse can be several things at once: a farmer's livelihood, a source of nitrogen runoff and a possible place to restore wetland. Denmark's Green Tripartite brings those interests into the same planning process. Green Land Fund

The national ambitions are large: 250,000 hectares of new forest, retirement of 140,000 hectares of carbon-rich lowland soils and a nitrogen reduction target of 13,800 tonnes. An approximately DKK 43 billion Green Land Fund provides a funding umbrella. Much of the practical work runs through 23 local groups, where municipalities, agriculture, nature organisations and the state must find arrangements that work on particular land.

What is documented — and what is not

Documented
All 23 local conversion plans were approved in principle by the end of 2025.
Documented
KL, the association of Danish municipalities, reported more than 5,600 potential projects and about 1,200 projects “under way or established” at the beginning of May 2026.
Important limit
That 1,200-project category ranges from preliminary investigations to completed wetlands. It is not a count of 1,200 finished conversions.
Unknown here
How many voluntary agreements have been signed, how many hectares have physically changed, and how much verified nitrogen, carbon or biodiversity effect has followed.
Our assessment
The model’s strength is coordinated local planning. The challenge is to turn mapped possibilities into agreements, completed projects and environmental improvements that can be measured.

A common table before a common map

According to the agricultural organisation Landbrug & Fødevarer, each group includes municipal representatives, two agricultural representatives, two from the Danish Society for Nature Conservation and one from the Danish Nature Agency. The groups build on existing river-basin cooperation. Their geography follows water as well as administrative boundaries. Landbrug & Fødevarer

That can help make competing needs visible. Land suitable for farming may also matter for drinking water, flood protection or habitat. Putting those uses on one map gives the participants something specific to discuss: which changes are possible, where, and at whose cost.

Government describes the plans as changing project lists. Municipal councils approve the parts within their boundaries, and proposals can be revised as investigations progress. The public MARS system links national figures, local plans and individual projects. MARS status system

A shared map lets people examine the same proposals. The coloured areas still need practical answers, however. An owner must be willing to participate; drainage and water conditions must suit the project; money, replacement land and staff may have to be found.

Odense Fjord: where the map admits its uncertainty

Around Odense Fjord, six municipalities joined agricultural and nature representatives and the state in agreeing a plan on 6 October 2025. It includes wetlands to reduce nitrogen, forest, lowland-soil projects, less intensive land use, mini-wetlands and areas with potential for nature.

Odense Municipality describes the boundaries as provisional and says owners will become involved as projects take shape. External funding and short state deadlines will influence which proposals go first. Some forest and nature projects may have to wait for support from utilities, foundations, businesses, residents or other partners beyond the national allocation.

To identify possible areas, the municipality combined information about soil, terrain, drainage, groundwater, nature, nitrogen retention, flooding, land use and ownership. That work narrows the search. Negotiation must then connect the public benefit with a change the owner can accept.

Voluntary participation is both the mechanism and the test

The national agency says implementation rests mainly on grants and voluntary participation by landowners and farmers. The tools include wetlands, lowland retirement, less intensive land use and forest planting. About DKK 740 million has separately been allocated for replacement land associated with land consolidation.

For farmers, the details of compensation and replacement land affect how the remaining farm can operate. Landbrug & Fødevarer presents MARS as a way to identify opportunities and sees the instruments as a means of meeting environmental requirements.

The Danish Society for Nature Conservation welcomes the plans while describing much of the portfolio as sketches. Its guide explains that municipalities and willing owners must now turn them into projects. Both organisations participate in the process; their assessments are part of the debate around it.

The agreements must work for owners and for the environment. Weak compensation can leave projects stalled. Choosing only the easiest agreements could leave the most valuable nitrogen, carbon or habitat work undone. The model needs to keep both concerns visible.

Who will carry the plans through?

KL, the association of municipalities, reported in May that all plans had been approved, with more than 5,600 potential projects and about 1,200 under way or established. That last category includes preliminary investigations as well as completed work. KL also reported applications during 2025 for nearly DKK 2 billion in EU funding covering more than 44,000 hectares of wetland and lowland projects.

In June, KL described difficulty recruiting qualified people and barriers municipalities could not remove alone. A project may need ecological assessment, valuation, negotiation, engineering, procurement and monitoring. A large portfolio places demands on all of those skills.

Additional government funding for local administration can help. Building experienced teams and trusted working relationships takes time as well. The pace of conversion may depend on those people as much as on the amount allocated to the fund.

Five stages between a mapped proposal and an environmental result

A project count becomes more useful when it shows how far the work has progressed. Five stages need to remain distinguishable:

  1. Mapped potential: areas and sketch projects identified in local plans.
  2. Approved and financed projects: proposals that have passed investigation and received a formal commitment.
  3. Voluntary agreements: owners and public bodies have agreed on land, compensation and implementation.
  4. Physical conversion: drainage changed, wetlands established, land retired or trees planted.
  5. Measured effect: verified changes in nitrogen, greenhouse gases, water quality, habitat or other stated outcomes.

Each stage has value. It also has its own timetable. Construction can be finished before an ecological effect can be measured, so a period of waiting needs to be explained rather than counted automatically as failure.

What would make the Danish model transferable?

Three features appear useful beyond Denmark: planning around water systems, bringing organised interests to one map and making project status public. They offer ways to turn broad disagreement into decisions about specific places.

Their usefulness elsewhere would depend on the foundations beneath them: trustworthy land records, capable municipalities, compensation funding, representative organisations and enforceable environmental goals. The meeting format alone cannot supply those conditions.

The next chapter will be written in agreements and changed fields. Following those changes through to the water, soil and habitats would show what the Danish approach can achieve, and what other places might learn from it.

What we will watch next

  • The distribution of the roughly 1,200 projects across investigation, commitment and completed construction.
  • Signed voluntary agreements and actual converted hectares, not only mapped potential.
  • Whether high-value but difficult projects advance, or the portfolio drifts toward easier agreements.
  • Municipal staffing, processing times and demand for grant funding.
  • Measured nitrogen and water-quality change in places such as Odense Fjord, with ecological time lags stated openly.
