    Can market fragmentation explain the limited success of political attempts to promote grain legume cultivation in Germany?
    (2025) Mittag, Franziska; Hess, Sebastian
    Grain legumes, such as field peas, field beans, sweet lupins and soybeans, are known to increase biodiversity within the appropriate crop rotation and are an important source of import-substituting feed protein. National and regional policy schemes have long tried to support the cultivation of grain legumes. Although many regions in Germany offer favourable conditions for grain legumes, previous subsidy schemes have failed to increase the area under cultivation and farmers report a lack of market incentives. Indeed, the available price data exhibit a substantial share of non-random missing values in weeks when grain legumes were not traded. We analyse these non-price periods using cointegration tests and single-hurdle Tobit models. The results indicate that regional price formation for grain legumes in German regions depends not only on a minimum quantity of the respective legume crop in supply but also on a favourable supra-regional soybean price: Regional grain legume markets are not integrated and show evidence of a fragmented market structure. This may explain why local grain legume value chains have failed to emerge in Germany, despite decades of policy attempts to support these crops.

    Sustainability certification in the digital era: a qualitative analysis of sustainability reports across product categories
    (2026) Boller, Meta Leonie; Grabinger, Toni; Zurwehme, Annikka; Krupitzer, Christian
    The food industry faces growing pressure to align sustainability goals with the rapid advance of digital technologies. This study explores how digitalization supports and transforms sustainability certification practices across diverse food product categories. Novelty lies in examining the interplay between digital technologies and sustainability reporting intensity, offering insights into how firms communicate and operationalize sustainability commitments. A qualitative content analysis was conducted on the sustainability reports of 21 companies using MAXQDA software, assessing the frequency and depth of reporting on sustainability focus topics and digital tools applied. The study includes multiple food product categories, such as coffee and tea, chocolate, grain products, dairy products, beverages, meat and fish, and tropical fruits. Results show that larger firms and those with higher turnover report more frequently and comprehensively on sustainability and digitalization. Three clusters of companies were identified, each reflecting shared sustainability challenges rather than specific product categories. The findings suggest that the relevance of digital technologies is more closely linked to addressing these cross-cutting sustainability challenges, and that high-value product segments provide the most promising starting points for integrating digital technologies into certification processes.
