- Policy interventions promoting sustainable food- and feed-systems: a Delphi study of legume production and consumptionPublication . Balazs, Balint; Kelemen, Eszter; Centofanti, Tiziana; Vasconcelos, Marta W.; Iannetta, Pietro P. M.The food- and feed-value systems in the European Union are not protein self-sufficient. Despite the potential of legume-supported production systems to reduce the externalities caused by current cultivation practices (excessive use of N fertilizer) and improve the sustainability of the arable cropping systems and the quality of human diets, sufficient production of high-protein legume grains in Europe has not been achieved due to multiple barriers. Identifying the barriers to the production and consumption of legumes is the first step in realizing new pathways towards more sustainable food systems of which legumes are integral part. In this study, we engage stakeholders and decision-makers in a structured communication process, the Delphi method, to identify policy interventions leveraging barriers that hinder the production and consumption of legumes in the EU. This study is one of a kind and uses a systematic method to reach a common understanding of the policy incoherencies across sectors. Through this method we identify policy interventions that may promote the production of legumes and the creation of legume-based products in the EU. Policies that encourage reduced use of inorganic N fertilizer represent an important step toward a shift in the increased cultivation of legumes. Relatedly, investment in R&D, extension services, and knowledge transfer is necessary to support a smooth transition from the heavy use of synthetic N fertilizer in conventional agriculture. These policy interventions are discussed within current EU and national plant-protein strategies.
- Integrated policy analysis to identify transformation paths to more-sustainable legume-based food and feed value-chains in EuropePublication . Balazs, Bálin; Kelemen, Eszter; Centofanti, Tiziana; Vasconcelos, Marta W.; Iannetta, Pietro P. M.The food- and feed-value systems in the European Union are not protein self-sufficient. Despite their potential to improve the well-being of arable cropping systems, sufficient production of high-protein legume grains in Europe has not been achieved due to multiple barriers. The reasons are multiple and span economic, agronomic, research, and extension services, as well as aspects of culture and traditional dietary habits. Given the well-documented advantages of legume-supported production systems and diets, that include ecosystem and health provisions, acknowledging and promoting legumes as cornerstone species for more sustainable agri-food systems is a necessary and logical step. This paper provides an integrated analysis of case studies and current policies that shape the production and consumption of legumes in Europe. This study identified three key pathways, which can be integrated into sustainable farming systems to support current and future food security challenges via the use of legumes and legume-based products. At each pathway, we identified several enablers that support the sustainability transformation of legume production and consumption in Europe.
- A multifunctional solution for wicked problems: value-chain wide facilitation of legumes cultivated at bioregional scales is necessary to address the climate-biodiversity-nutrition nexusPublication . Iannetta, Pietro P. M.; Hawes, Cathy; Begg, Graham S.; Maaß, Henrik; Ntatsi, Georgia; Savvas, Dimitrios; Vasconcelos, Marta; Hamann, Karen; Williams, Michael; Styles, David; Toma, Luiza; Shrestha, Shailesh; Balázs, Bálint; Kelemen, Eszter; Debeljak, Marko; Trajanov, Aneta; Vickers, R.; Rees, Robert M.Well-managed legume-based food systems are uniquely positioned to curtail the existential challenge posed by climate change through the significant contribution that legumes can make toward limiting Green House Gas (GHG) emissions. This potential is enabled by the specific functional attributes offered only by legumes, which deliver multiple co-benefits through improved ecosystem functions, including reduced farmland biodiversity loss, and better human-health and -nutrition provisioning. These three critical societal challenges are referred to collectively here as the “climate-biodiversity-nutrition nexus.” Despite the unparalleled potential of the provisions offered by legumes, this diverse crop group remains characterized as underutilized throughout Europe, and in many regions world-wide. This commentary highlights that integrated, diverse, legume-based, regenerative agricultural practices should be allied with more-concerted action on ex-farm gate factors at appropriate bioregional scales. Also, that this can be achieved whilst optimizing production, safeguarding food-security, and minimizing additional land-use requirements. To help avoid forfeiting the benefits of legume cultivation for system function, a specific and practical methodological and decision-aid framework is offered. This is based upon the identification and management of sustainable-development indicators for legume-based value chains, to help manage the key facilitative capacities and dependencies. Solving the wicked problems of the climate-biodiversity-nutrition nexus demands complex solutions and multiple benefits and this legume-focus must be allied with more-concerted policy action, including improved facilitation of the catalytic provisions provided by collaborative capacity builders—to ensure that the knowledge networks are established, that there is unhindered information flow, and that new transformative value-chain capacities and business models are established.
