Minimizing the number of players involved in the supply chain helps to make it safer and more secure, which helps to protect farmers and producers as well as their end-users. Providing flexibility in licensing requirements for direct selling, e-commerce, and food transport can also help small producers and agricultural businesses to find alternative market opportunities since flexibility is relatively associated with weak/strong position of farmers and presence of long/short food supply chains.
