Periodic Reporting for period 1 - VALERECO (Valorization Legumes Related Ecosystem Services)
Berichtszeitraum: 2024-06-01 bis 2025-11-30
The project’s overall objective is to promote adoption of underutilized legume crops as a key component of diversified and climate-resilient farming systems. It works across European regions with diverse soil-climate conditions to quantify and enhance legume ES, including soil fertility improvement through biological nitrogen fixation, biodiversity support, weed and pest suppression, and reduced reliance on chemical inputs. A key strategy is establishing Living Labs (LLs) that bring together farmers, advisors, researchers and other stakeholders to co-create, test and demonstrate legume-based solutions under real farming conditions.
In parallel, VALERECO emphasises knowledge exchange, capacity building and decision support. The Digital Legume Information Hub (DLIH) provides decision-support systems (DSS), training materials and open-access platforms to support decision-making by farmers, advisors and agri-food chain stakeholders. By linking scientific evidence, stakeholder engagement and policy-relevant insights, VALERECO contributes to the transition towards environmentally friendly and economically sustainable agricultural systems, strengthening farm resilience amid major challenges in European agriculture.
Legumes and their ES are investigated in two-factorial field trials where crop rotation and agroecological crop management consist the experimental factors. Agroecological crop management strategies include cultural practices as intercropping, cover cropping, mechanical weeding, reduced tillage systems etc. The experiments are to be conducted for three growing seasons in a wide range of soil-climate factors in the different LLs. The first trial year was completed with data collection focused on crop growth and yield, legume nitrogen fixation, soil quality traits, biodiversity indicators and weed parameters.
Complementary controlled-environment experiments were set up to assess drought and cold tolerance of selected legume species using physiological and molecular analyses to identify climate resilience traits. In parallel, behavioural and socio-economic research activities established a robust empirical baseline on perceptions, knowledge and decision-making related to legume cultivation among farmers, consumers and retailers across participating countries. This work generated harmonized datasets to support the design of future behavioural strategies and decision-support tools. The technical groundwork for the upcoming economic, environmental and life-cycle assessments (LCA) was prepared, as well as for DSS and DLIH development.
Overall, the first reporting period delivered the core scientific background to serve project goals in its subsequent implementation stages.
To quantify project impacts, data are collected and analysed on crop performance and climate resilience, soil and biodiversity indicators and weed dynamics. Cause–effect relationships are identified whenever possible to explain observed phenomena and draw more robust conclusions. In addition, the project integrates physiological, molecular and systems-level assessments of legumes’ responses to abiotic stress, strengthening the scientific basis for climate-resilient crop diversification strategies. Farmer, consumer and value-chain actor behavioural patterns are also under investigation to provide a qualitative illustration of VALERECO impacts. Overall, LL establishment creates a long-term co-creation and experimentation space that goes beyond the “plateaus” of conventional field trials.
While the project is still at an early stage, these results already extend the state of the art by enabling robust comparison, upscaling and synthesis across regions and disciplines. Further uptake and success will follow through the second and third field trial years, completion of environmental and economic assessments, validation of decision-support tools, and sustained engagement with farmers, policymakers and value-chain actors. Project ambitions rest on the hypothesis that continuous interaction between scientific evidence and real decision-making contexts opens new windows for reintroducing legumes in European fields.
