This Deliverable report presents the impact of key factors influencing decision making of farmers and consumers to uptake legume cultivation and, respectively, the choice to include legumes into diets. Results provide guidance on determinants of positive behavioural change towards legume inclusion. Farmer and consumer analyses are based on survey data for the UK farmers and consumers, and findings are discussed comparatively in the context of European production and consumption and main factors potentially influencing behaviours and trends. The report informs how we may operate more effectively to affect behavioural change positively towards legume inclusion.
