Europe Quantifies the Cost of Wild Bee Decline

Europe Quantifies the Cost of Wild Bee Decline

A collapse of wild pollinators by 2030 would result in a loss of well-being of 24 billion euros for Europe in the broad sense (12 billion for the EU alone), primarily borne by consumers through price increases. This is the central figure from a study published in Nature Communications in November 2025 — the first to precisely quantify this risk by country and by crop, combining ecological and economic models at the continental scale.

This figure changes the nature of the debate. Protection of pollinators had until now been driven by ecological and moral arguments that the most reluctant member states have regularly dismissed in the name of agricultural competitiveness. The study turns the argument around: the states that are slowing down protective rules are precisely those that would absorb the heaviest bill.

The Essentials

• A collapse of wild pollinators by 2030 would reduce European agricultural yields by 8% on average, according to a November 2025 Nature Communications study
• The annual loss of well-being would reach 24 billion euros for Europe in the broad sense (12 billion for the EU alone) and 34.4 billion euros globally
• Crops dependent on pollination — fruits, vegetables, oilseeds — concentrate the bulk of economic risk
• Member states that oppose European regulation on pesticides and nature restoration are among the most exposed
• Political instruments exist — the Nature Restoration Law, Farm to Fork, CAP mechanisms — but their implementation remains incomplete

8% Fewer Yields: What the Number Really Says

Wild bees do not pollinate like domesticated bees. They travel shorter distances, are more specialized by crop and season, and their pollination efficiency per contact is often superior to that of managed hives. For rapeseed, apple trees, or strawberries, their presence is not interchangeable with that of farmed bees.

The Nature Communications study reconstructs this mechanism at the European scale. It combines data on current wild pollinator populations, distribution models under different pressure scenarios (habitat loss, pesticides, climate change), and agricultural yield data crop by crop. The result: a complete collapse of wild populations by 2030 would translate into an average loss of 8% in yields of pollination-dependent crops across Europe.

This 8% figure may seem modest. It is not. European agriculture operates with thin net margins — often below 5% for major crops. A yield loss of this magnitude, permanent and uncompensated, would erase the profitability of a significant fraction of farms. At the sectoral level, the estimated loss of well-being of 24 billion euros for Europe in the broad sense represents the equivalent of several combined national agricultural budgets.

The geographic distribution of risk is uneven. Regions of southern and eastern Europe, where wild pollinator density remains high but agricultural pressures are intensifying, would be among the hardest hit. Spain, Romania, Poland, and Hungary stand out in sensitivity analyses as zones of high economic exposure. These are also, for the most part, member states that have actively resisted European nature regulation over the past two years.

The Political Reversal: Reluctant States Pay First

The paradox documented by the study deserves to be named clearly. Since 2022, several member states have fought against or gutted two major texts: the Nature Restoration Law and the Farm to Fork plan, which notably provided for a 50% reduction in chemical pesticide use by 2030. These resistances have been carried in the name of food sovereignty, competitiveness, and refusal of additional regulatory constraints on the agricultural sector.

The 2025 study reverses this logic. By mapping potential economic losses by country, it shows that the states most exposed to pollinator risk are precisely those whose agricultural systems remain the most intensive and least diverse from an ecological perspective. Dependence on chemical inputs has reduced wild pollinator habitats — hedgerows, fallow land, permanent grasslands — that provide the pollination service. Short-term savings from regulatory protection are medium-term debt on yields.

This is not a new argument in principle. But it is the first time it has been quantified with this geographic and sectoral precision for Europe. And precision changes politics: it becomes more difficult to oppose a diffuse regulatory cost to an abstract ecological benefit when the map of losses is superimposable on the map of resistance.

The European Commission now has a negotiation tool. The question is whether it will use it.

What Wild Pollinators Do That Hives Don’t

There are approximately 2,000 species of wild bees in Europe. To these are added hoverflies, butterflies, beetles, and pollinating flies. This diversity is not a taxonomic luxury: it is functional insurance.

Each species occupies a different temporal and spatial niche. Some pollinate early in spring, when temperatures are still low and hives are inactive. Others reach flowers whose morphology excludes honeybees. Tomatoes, for example, require vibration pollination — a behavior that bumblebees naturally practice and that honeybees do not master. European tomato production greenhouses depend massively on commercial bumblebees, themselves sourced from breeding that draws on wild populations.

The economic logic of substitution — replacing wild pollinators with farmed hives — runs up against several practical obstacles. First, hives do not cover the full spectrum of pollination services. Second, beekeeping itself depends on the health of wild populations for genetic renewal and pathogen resistance. Third, the cost of artificial pollination, where technically possible, is incomparable to the free service rendered by wild insects.

The Nature Communications study quantifies this irreplaceability: in scenarios of partial wild pollinator decline, domesticated bees compensate for only a fraction of yield losses. The ecosystem service has value precisely because it is not reproducible at lower cost.

European Instruments Exist — Their Implementation Is the Problem

Europe is not without tools. The Nature Restoration Law, finally adopted in June 2024 after a tumultuous political passage, requires member states to restore 30% of their degraded ecosystems by 2030. Agricultural environments explicitly figure among the targets: permanent grasslands, hedgerows, ponds, flowering fallows. These are exactly the habitats that support wild pollinator populations.

The Common Agricultural Policy (CAP), revised for the 2023-2027 period, incorporates eco-schemes designed to remunerate farmers for biodiversity-friendly practices. In theory, a farmer who maintains flowering strips or reduces inputs receives a supplementary payment. In practice, implementation varies considerably from one member state to another, and several countries have chosen eco-schemes with low requirements that generate limited ecological benefit.

On pesticides, the situation is more fragile. The proposal for a regulation on the sustainable use of pesticides (SUR) was withdrawn by the Commission in 2024 under pressure from member states and part of the European Parliament. The objective of reducing chemical pesticide use by 50% by 2030 is no longer carried by a binding text. It remains in the rhetoric, without enforcement mechanisms.

This gap between stated ambition and actual instruments is precisely what the Nature Communications study allows us to cost. Each year of delay in implementing protective measures represents additional degradation of habitats and pollinator populations. The 2030 window that researchers use as the horizon for collapse is not arbitrary: it corresponds to the duration during which current political decisions will take effect.

Actors Making Progress Despite Institutional Blockage

While European negotiations advance slowly, ground-level initiatives are producing documented results. In France, the Agrifaune program coordinated by the National Federation of Hunters and agricultural organizations has restored thousands of kilometers of hedgerows and grassy strips on cereal farms. Initial evaluations show a measurable increase in pollinator diversity in treated zones, with effects on yields of adjacent crops.

In the Netherlands, the Deltaplan Biodiversiteitsherstel program has mobilized since 2018 all agricultural sectors, provinces, and nature conservation organizations around quantified restoration objectives. The share of agricultural land certified as pollinator-friendly has increased significantly. The program is financed partly by CAP funds, partly by private contributions from agricultural cooperatives.

At the research level, the European consortium SURPASS2, funded by the Horizon Europe program, has developed pollinator risk mapping tools at the field scale. These tools allow farmers to identify the areas of their holdings most dependent on wild pollinators and to target improvements accordingly. Distribution of these tools to agricultural advisors is underway in a dozen member countries.

These initiatives share a logic that directly aligns with the conclusions of the Nature Communications study: protecting pollinators is not a constraint imposed on agriculture, but an investment in agricultural productivity itself. The difficulty is in scaling this demonstration to public policy, where political resistances are concentrated.

What the 24 Billion Says to the CAP

The CAP represents approximately one-third of the European Union’s budget, nearly 387 billion euros over the 2021-2027 period. It is supposed to remunerate farmers for sustainable practices while supporting their competitiveness. It achieves this imperfectly on both fronts.

The Nature Communications study provides a budgetary argument that negotiators of the next CAP, whose revision will begin in 2026, cannot ignore. If a collapse of pollinators entails a loss of well-being of 24 billion euros per year for Europe in the broad sense, then financing protective habitat measures at a fraction of this amount is economically rational. The argument is not ecological, it is accounting.

This argument has a limitation that the study acknowledges itself: the benefits of protection are diffuse and materialize over several years, while regulatory costs are immediate and localized on farms that must modify their practices. This temporal asymmetry is at the heart of political resistance. The response is not to deny the asymmetry, but to finance it — this is precisely what CAP eco-schemes are supposed to do, when correctly calibrated.

The real question posed by the study is therefore not whether protecting pollinators is worth 24 billion. It is whether European institutions are capable of designing financing mechanisms that compensate for short-term transition costs for farmers, while preserving the ecosystem service that sustains their activity long-term. Studies like this one, which make the economics of biodiversity visible, help pose the problem correctly. They do not solve it.

On this terrain, the tools are known. What is missing is the political will to apply them commensurate with the stakes that researchers have just quantified. The next CAP revision will be a serious first test.
