With the intensification of agriculture, the simplification of crop rotations, and the rise in demand for meat, dairy and cereal products, legume production and consumption are at an historic low in Europe. But as the environmental consequences of agriculture (biodiversity loss, high greenhouse gas emissions, water pollution) and the health outcomes of modern diets (heart disease, cancer, diabetes, obesity) become better known, so great and varied hopes are being expressed about the future role of legumes in the food system. This paper catalogues and scrutinises these hopes, mapping the promissory narratives now orbiting around legumes. It identifies six food futures, each of which is made possible through the greater use of legumes in various production, processing, marketing and consumption contexts. These promissory narratives are theorised as contrasting responses to three major areas of contestation in the food systems literature. Namely i) the sustainability of livestock management, ii) the role of technology in different visions of the ‘good diet’, and iii) the merits of different models for how to make agricultural management more sustainable. It identifies the promiscuity of legumes – in terms of the range of food futures they permit – before distilling three points of consensus amongst advocates of the potential of legumes. These points of consensus relate to their nitrogen fixing capacity, their high protein content, and their long-standing historical role in the context of European food and farming. This map of legume dreams serves to guide deliberations amongst researchers, policymakers and industry stakeholders about the futures of plant-based food in Europe.

随着农业的集约化、轮作的简化以及对肉类、奶制品和谷物产品的需求增加，欧洲豆类生产和消费处于历史低位。但随着农业对环境的影响（生物多样性丧失、温室气体排放量高、水污染）和现代饮食对健康的影响（心脏病、癌症、糖尿病、肥胖症）越来越为人所知，人们对豆类在粮食系统中的未来作用。本文对这些希望进行了分类和审查，描绘了现在围绕豆类的承诺叙述。它确定了六种食品期货，每一种都是通过在各种生产、加工、营销和消费环境中更多地使用豆类来实现的。这些承诺性叙述被理论化为对食品系统文献中三个主要争论领域的对比反应。即 i) 牲畜管理的可持续性，ii) 技术在“良好饮食”的不同愿景中的作用，以及 iii) 如何使农业管理更具可持续性的不同模式的优点。它确定了豆类的杂乱性——就它们允许的食品期货范围而言——在提炼豆类潜力的倡导者之间的三点共识之前。这些共识点与它们的固氮能力、高蛋白质含量以及它们在欧洲食品和农业背景下的长期历史作用有关。这张豆类梦想地图用于指导研究人员的审议，
