The Soils for Europe Conference in Coimbra arrived at a moment when the conversation around European soils is changing character. For much of the past decade, soil science in Europe has been dominated by diagnosis: mapping degradation, quantifying carbon losses, cataloguing contamination, and documenting the steady attrition of soil biodiversity. The gathering of roughly 500 participants under the EU Mission “A Soil Deal for Europe” signals a deliberate pivot from that diagnostic phase toward implementation, a shift that carries its own scientific and institutional challenges. Transitioning from research to action requires not only that knowledge exists, but that it is organised, accessible, and translated into forms that farmers, land managers, and policymakers can actually use.

The scale of the underlying problem helps explain why the European Union elevated soil health to the status of a Mission. Soils are among the slowest-renewing resources on the continent; the formation of a single centimetre of topsoil can take centuries, while erosion, compaction, and sealing can destroy it in a single season. The European Commission’s estimate that 60 to 70 percent of EU soils are unhealthy reflects cumulative pressures operating over decades: agricultural intensification, urban expansion, industrial contamination, atmospheric deposition, and climate-driven drying in southern regions. Because these pressures interact—erosion strips the carbon-rich top layer, which in turn weakens structure and biodiversity, which further accelerates degradation—the response cannot be piecemeal. This systemic character is precisely why the Mission framework, with its eight interlocking objectives, was designed to coordinate research, monitoring, and practice across member states rather than leaving soil policy fragmented across sectors.

The entry into force of the Directive on Soil Monitoring and Resilience in December 2025 represents a legal milestone that researchers at the conference repeatedly framed as transformative. For the first time, soil health in the EU is governed by dedicated legislation rather than by provisions scattered across water, waste, and agricultural law. The three-year window for member states to transpose the directive into national law creates an immediate demand for harmonised monitoring methodologies, comparable indicators, and shared data infrastructure. This is where the scientific community’s contribution becomes concrete: without agreed metrics for soil organic carbon, biodiversity, structure, and contamination, the directive’s ambitions cannot be assessed consistently across borders. The launch of the Soil Data Catalogue, developed by the SoilWise project with the EU Soil Observatory, addresses one of the most persistent obstacles in this domain. Soil data in Europe has historically been dispersed across national surveys, research institutes, and legacy datasets collected under incompatible standards. Making such data findable, accessible, interoperable, and reusable—the FAIR principles that now underpin European research infrastructure—is a precondition for both the directive’s implementation and for the research agenda that SOLO’s roadmaps articulate.

The timing relative to the Common Agricultural Policy negotiations for 2028 to 2034 gives the conference’s policy sessions particular weight. The CAP remains the largest financial instrument shaping land management across the EU, and its design determines whether farmers are rewarded for practices that build soil health—cover cropping, reduced tillage, diversified rotations, agroecological infrastructure—or whether incentives continue to favour approaches that externalise soil costs. The session organised by SOLO with PAN Europe and the Leibnitz Centre for Agricultural Landscape Research brought together the constituencies whose alignment is essential: the Commission officials who draft regulations, the researchers who generate evidence, the farmers who implement practices under real economic constraints, and the advisory services who mediate between science and field. The recommendations emerging from such dialogues matter because the historical record shows that soil-relevant measures in agricultural policy succeed or fail largely on questions of design: how payments are structured, how compliance is verified, and whether advisory systems have the capacity to support change at the farm level.

SOLO’s own structure illustrates a methodological evolution in how European research projects approach knowledge generation. As a Coordination and Support Action rather than a conventional research project, its mandate is explicitly about synthesis, coordination, and agenda-setting. The nine Think Tanks, each co-developing roadmaps with stakeholders ranging from researchers to farmers to educators, embody a transdisciplinary model in which the boundaries between knowledge production and knowledge application are deliberately blurred. The open co-creation session in Coimbra, where participants critiqued the draft roadmaps covering the eight Mission objectives plus nature conservation of soil biodiversity, reflects an emerging norm of research validation through stakeholder scrutiny. This approach acknowledges a lesson learned repeatedly in environmental science: research agendas designed without practitioner input tend to produce knowledge that is scientifically elegant but operationally irrelevant, while stakeholder-driven agendas risk missing emerging problems that only fundamental research can anticipate. The iterative feedback loop—roadmaps drafted by Think Tanks, tested in regional co-creation nodes, and revised after public review—is designed to navigate between these failure modes.

The pilot Key Performance Indicators developed with the Mission Soil Board deserve particular attention, because measuring the impact of research funding is notoriously difficult. Traditional metrics—publications, citations, project deliverables—capture scientific output but say little about whether awareness has grown, whether decisions have changed, or whether sustainable soil management practices have actually been adopted on the ground. The KPI set presented at the conference attempts to bridge this gap by tracking outcomes along the pathway from research to societal change. This is methodologically demanding: attribution is contested, time lags between research and adoption can span decades, and baseline data on farmer behaviour and policy influence are often absent. That SOLO is piloting these indicators with the Mission Board suggests an institutional willingness to be held accountable for impact, which is itself a notable development in how EU research programmes evaluate their own effectiveness.

The Think Tank on the EU’s global soil footprint addresses a dimension of soil health that remains underappreciated in public discourse. Europe’s soils may be degrading within its borders, but European consumption patterns exert pressure on soils far beyond them. Imported commodities—soy for livestock feed, cocoa, coffee, palm oil, timber—embed soil degradation in exporting regions, meaning that the EU’s apparent progress on domestic soil health can be partly offset by displacement effects elsewhere. This concept, familiar from carbon footprint accounting, is more difficult to operationalise for soils because degradation is harder to measure remotely than deforestation or emissions. A strategic pathway to reduce the EU’s global soil impact will likely need to combine trade policy instruments, supply chain due diligence, and consumption-side measures, all informed by better data on where and how European demand drives soil change abroad. The conference’s inclusion of this topic among its highlights signals that the Mission’s ambition extends beyond territorial soil management to Europe’s role in the global soil system.

The participatory and sensory dimensions of the conference programme—the Soil Banquet’s edible landscape, the soil ecoacoustics workshop, the Soil Collage game, the farmers’ market at the Botanical Garden of Coimbra—should not be dismissed as decorative. They respond to the Mission’s eighth objective, increasing soil literacy in society, which recognises that soil suffers from a visibility problem. Unlike forests or oceans, soils are largely hidden, and their degradation is gradual and often invisible until thresholds are crossed. Research on environmental perception consistently shows that people protect what they can perceive and understand. Translating soil science into embodied experiences—tasting a landscape built from locally sourced ingredients, listening to the acoustic signatures of living soil—represents an attempt to build the affective and cognitive foundations on which behavioural and political change depend. Around 150 posters across three sessions, alongside the policy debates, indicate that the scientific core of the Mission remains robust; the creative formats are an addition to, not a substitute for, technical exchange.

The involvement of nearly 40 co-organising projects reveals the scale of the EU’s investment in soil research under Horizon Europe. Projects such as AI 4 Soil Health, Best4Soil, Bin2Bean, CURIOSOIL, DeliSoil, ECHO, InBestSoil, MARVIC, MINAGRIS, NBSOIL, SOILL, and their many counterparts each address fragments of the soil challenge—carbon farming methodologies, nutrient recycling, contamination assessment, nature-based solutions, living lab coordination, digital soil mapping. The risk inherent in such a distributed portfolio is fragmentation: dozens of projects producing incompatible datasets, overlapping recommendations, and duplicated effort. The conference itself, and the coordination role SOLO plays alongside the Mission Soil Secretariat, function as mechanisms of integration, ensuring that the whole of this research investment exceeds the sum of its parts. The presence of Living Labs—real-world sites where solutions are tested with farmers and land managers under actual conditions—embodies the Mission’s insistence that soil research must be grounded in practice rather than confined to experimental stations.

Looking toward 2030, the deadline the Mission has set for leading the transition to healthy soils, the Coimbra conference marks a midpoint assessment rather than a conclusion. The establishment of 100 Living Labs and Lighthouses, the harmonised monitoring framework now backed by legislation, and the research roadmaps awaiting finalisation together form an architecture for the remaining years. Whether that architecture delivers measurable improvement in the health of Europe’s soils will depend on factors no conference can control: the ambition of national transposition of the soil directive, the orientation of the next CAP, the willingness of agricultural sectors to adopt changed practices, and the trajectory of climate pressures that increasingly test the resilience of the very systems soil scientists are working to protect. What the conference demonstrated is that the European soil community has moved decisively from asking what is wrong to organising around what can be done—a shift whose significance will only become clear in the harvests, monitoring reports, and policy evaluations of the years ahead.
