The role of biodiversity in consumer research on food : a review and research agenda
(2025) Schneider, Deborah; Osieja, Sanja; Herbes, Carsten; Weinrich, Ramona
The move towards sustainable consumption has drawn significant attention from scholars and practitioners alike. Biodiversity is an integral part of environmental sustainability and food security, but it has received little attention in consumer research. Findings are fragmented into how biodiversity as a product attribute affects consumer food choices. Thus, we conducted a systematic literature review on consumer research on biodiversity in the context of food choice. We reviewed 45 papers published between 2014 and March 2025. Our analysis was guided by the TCCM (Theories, Contexts, Characteristics, and Methodology) framework for developing a systematic literature review. We examined how biodiversity was conceptualized and defined within the studies and towards study participants. Our findings show that biodiversity as a product attribute generally has positive effects on consumer attitude, willingness to pay, and product choice. However, knowledge about biodiversity and the inherent trade-offs in product choices remains limited, so consumers cannot realistically factor biodiversity into their decision-making. We find that research has taken a narrow view of biodiversity, qualitative studies are rare, and few efforts have been made to build theoretical perspectives from empirical data. We conclude with a proposed agenda for future research and a tentative definition of biodiversity for social science.
