Intensify production, transform biomass to energy and novel goods and protect soils in Europe—A vision how to mobilize marginal lands

Open access

Abstract

The rapid increase of the world population constantly demands more food production from agricultural soils. This causes conflicts, since at the same time strong interest arises on novel bio-based products from agriculture, and new perspectives for rural landscapes with their valuable ecosystem services. Agriculture is in transition to fulfill these demands. In many countries, conventional farming, influenced by post-war food requirements, has largely been transformed into integrated and sustainable farming. However, since it is estimated that agricultural production systems will have to produce food for a global population that might amount to 9.1 billion by 2050 and over 10 billion by the end of the century, we will require an even smarter use of the available land, including fallow and derelict sites. One of the biggest challenges is to reverse non-sustainable management and land degradation. Innovative technologies and principles have to be applied to characterize marginal lands, explore options for remediation and re-establish productivity. With view to the heterogeneity of agricultural lands, it is more than logical to apply specific crop management and production practices according to soil conditions. Cross-fertilizing with conservation agriculture, such a novel approach will provide (1) increased resource use efficiency by producing more with less (ensuring food security), (2) improved product quality, (3) ameliorated nutritional status in food and feed products, (4) increased sustainability, (5) product traceability and (6) minimized negative environmental impacts notably on biodiversity and ecological functions. A sustainable strategy for future agriculture should concentrate on production of food and fodder, before utilizing bulk fractions for emerging bio-based products and convert residual stage products to compost, biochar and bioenergy. The present position paper discusses recent developments to indicate how to unlock the potentials of marginal land.

TL;DR

This position paper argues that Europe’s marginal, degraded, and contaminated lands can be mobilized for sustainable intensification, biomass/energy production, and novel bio-based goods while protecting soils. It synthesizes soil degradation evidence, amendment and crop options, microbial tools, precision agriculture, and indicator/valuation frameworks from the EU-FACCE JPI INTENSE project.

Key findings

  • Marginal/degraded lands are widespread: all forms of degradation amounted to about 10 million ha per year in Europe, with main causes identified as overgrazing (35%), agriculture (28%), deforestation (30%), fuel wood production (7%), and industrialization (4%). The EU has approximately three million sites with potentially polluting activities, of which an estimated 250,000 may need urgent remediation; remediation costs usually range from €50,000 to €500,000 per site in 40% of reported cases.
  • The paper proposes a toolbox combining precision agriculture, organic amendments (compost, manure/digestate, biochar), adapted crop rotations, phytomanagement, and beneficial plant-microbe interactions. It reports soil carbon sequestration potential up to 45 Tg C per year, fertilizer uptake of about 50% for N, 10–25% for P, and 50–60% for K, and notes that biological nitrogen fixation accounts for approximately 65% of nitrogen currently utilized in agriculture.
  • Biochar is described as up to 90% carbon by mass and useful for carbon sequestration, soil structure, and contaminant stabilization, but its research is still in its infancy. Compost and digestate are highlighted as organic amendments, with almost 50% of compost produced in Europe used in agriculture; about 32% of composts originate from biowaste and 9% from mixed waste.
  • The INTENSE project investigates test sites in France, Germany, Italy, Norway, Poland, and Spain representing low productivity, water scarcity, inappropriate land use, and contamination by trace elements or organic pollutants. The paper outlines decision-tree and functional role-based valuation approaches to guide management and economic assessment.

Methods

  • Design: position/vision paper synthesizing literature, project experience, and conceptual frameworks rather than reporting a single primary experiment.
  • Data/sample: draws on the EU-FACCE JPI INTENSE project’s test sites in six European countries, with site descriptions covering climate, lithology, soil properties, contamination, amendments, and crops.
  • Main analysis: narrative synthesis of soil degradation, amendments, crop rotation, phytomanagement, microbial interactions, indicators (including DPSIR), decision trees, and economic valuation models.

Limitations

  • Stated: no indicator perfectly reflects reality; data on macro-aggregate formation and stabilization under reduced disturbance are scarce; biochar research is in its infancy; feasibility of biomass valorization routes is still in its infancy; remote sensing is scarcely used for marginal lands; empirical literature on species diversity valuation from a farmer’s perspective is scarce; Table 5 highlights knowledge gaps.
  • Stated: many policy makers seem unfamiliar with opportunities for modern, ecologically sound agriculture, and little new science has been shared with farmers, extension services, or other agricultural scientists and technicians.
  • Evident: as a vision/position paper, it does not report complete experimental results from the INTENSE sites; many quantitative claims are cited from other studies rather than newly generated by the paper.

  • Industrial biomass figure conflicts with material-use share

    Minor

    Ten percent of the stated 12 billion tons is 1.2 billion tons of biomass for material use. The paper also reports only 1.26 million tons for industrial purposes in 2011-roughly a thousandfold less-without distinguishing the categories in a way that reconciles the figures.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
