Multi-farm CSAs allow the farmer to retain control over their products (in terms of setting production levels and/or prices), but farmers use a collectively-owned (which sometimes also includes consumer owners), centralized system to market, sell and distribute their products. Schmidt, et al. (2011) conducted a case study on a farmer collaborative that aggregates, markets and distributes local products to individuals, businesses, retailers and restaurants through both a multi-farm CSA (500 members and seven types of shares) and a wholesale marketing program (intervalefoodhub.com). The model provided favorable returns to producers, but one of the main challenges faced was maintaining equity among producers given the wide variety of volume and product type. The Oklahoma Food Cooperative and High Plains Food Cooperative (in Kansas and Colorado) are similar models seeking to maintain some control with producers. However, multi-farm CSAs have inherently limited volume by their pre-contract orientation (e.g., institutions pre-purchase shares of production before the production season begins, which means that ‘excess’ produce cannot be sold to other clients).
