Introduction
The Economics of Food Systems Unit (D4) at the Joint Research Centre presents a collection of studies that examines socio-economic and environmental implications in a range of policy aspects related to the food-systems. The collection is organised in four thematic strands – agri-food, bioeconomy, global dimensions, and data-driven tools – each offering evidence-based insights and for some of them concrete policy suggestions.
As related to the Agri Food Sector, we highlight a relevant report analysing the economic effects of reduction of pesticides to analytical limit of quantification for imported products. The study suggests that closer alignment could benefit EU producers, while underlining that further detailed assessment is necessary to address the instances where effects on prices or competitiveness could be less favourable. Colleagues contributed to a join analysis of distributional impact of energy price shock following the 2026 war in the Middle East showing that the burden of energy price shocks fall hardest on lower-income households. More related to food chain aspects, we published an analysis on “generational renewal in agriculture” investigating aspects in farm succession showing that farmers invest significantly more in modernization and innovation once a successor is identified and actively involved; an additional interesting analysis on land-access in selected countries (Belgium, Ireland and Poland) confirms that an early identification of a successor mitigates farm contraction. Another study focused on a methodology for stress testing EU food security to map critical supply-chain vulnerabilities. On the front of new technologies, research assesses the potential of gene-edited biological nitrogen-fixation technologies to reduce nitrogen surpluses in EU agriculture.
The digest’s bioeconomy section of studies quantifies livestock value-chain contributions, estimating €256 billion in 2023 value added (≈ 30 % of EU biomass-producing activities). An analysis of public agricultural R&D highlights the potential of shifting investment from yield-maximisation toward input-saving technologies and the importance of revitalising public R&D, removing innovation barriers and tailoring technology pathways to regional contexts.
On more global issues, a study investigates the mechanisms behind the growth of global agricultural greenhouse gas emissions looking at changes in emissions into output growth, unit of input and total factor productivity (TFP). We contributed with our modelling to the EAT Lancet new report on importance of changing diets at global level. Research on climate cycles shows the heterogeneity of effects of El Niño and La Niña on food price across regions and commodities. Focusing on Africa, a study on non-tariff measures (NTMs) within the African Continental Free Trade Area (AfCFTA) indicates positive effects of regulatory harmonisation on welfare. A household survey-based assessment of cocoa producers in Cameroon reveals a widespread living income gap and suggests moderating measures. Another research in West Africa, shows that climate risk management, finance, and extension services are essential to maintain an adequate input utilisation. Finally, an evaluation of recent US trade-policy shifts indicates limited direct effects on African economies however showing indirect exposure, reinforcing the strategic importance of deepening intra-African trade.
The digest concludes with advancement on data analysis; a proof-of-concept study of an LLM-based pipeline (GPT Scheduler) for semi-automating invasive-alien-species impact assessments. While AI markedly speeds literature screening, expert oversight remains critical to ensure data quality and mitigate algorithmic bias. The authors recommend integrating AI tools within transparent, expert-led workflows.
