Local food systems and short food supply chains have drawn a lot of attention over the past decades. While consumers’ preferences and willingness to pay for local food have been widely explored in high-income countries, farmers’ multifactorial choice of marketing channels remains poorly investigated. This study focuses on the fresh vegetable sector in Wallonia and identifies important factors affecting farmers’ decision to participate in different types of local short food supply chains. We use qualitative data from semi-structured interviews, focus group discussions and sectorial events, and quantitative data from an online survey with 82 farmers, comprising a discrete choice experiment to conduct our research. We identify general preferences and sources of preference heterogeneity using econometric techniques (mixed logit models). Our results will be presented at the seminar, hoping for your valuable feedback.
