“…A last group of studies focuses on the structures of distribution channels . Their interest stems from the increasing relevance of food traceability, regulations and monitoring systems in relation to securing public health (Opara, 2003; Ahumada and Villalobos, 2009), paralleled by a growing consumer interest in the origin of food (e.g., Marsden et al ., 2000; Bätzing and Ermann, 2001; Renting et al ., 2003; Ilbery and Maye, 2006; Delaware Valley Regional Planning Commission, 2010; Abatekassa and Peterson, 2011; Carey, 2011; Miller et al ., 2016). Such studies often start from the perspective of regional food production, and ask where and how this food is distributed—often through niche markets, such as farmers' markets (Lyson et al ., 1995; Marsden et al ., 2000; Brown, 2002; Payne, 2002; Gillespie et al ., 2007; Brown and Miller, 2008; Smithers et al ., 2008; Brinkley, 2017).…”
