Although an exact definition is contested, the sharing economy generally refers to models of sharing access and/or ownership of resources, goods and services, whether with or without a monetary exchange. Broader definitions may include acts of reselling, swapping, gifting, renting and lending as well,. This phenomenon exists across many sectors, and has been especially helped by digital mediation (e.g. online platforms such as Wikipedia or AirBnb). In agriculture, common forms of the sharing economy include community gardens, food swapping, and alternative food networks (AFNs), such as community supported agriculture (CSAs) or solidarity purchasing groups (SPGs). Sharing in agri-food systems can occur both on the production and the consumption end. For instance, farmers can share equipment used for production, or they can share the labor and harvest from a community garden. In addition, different forms of capital, whether human, social, natural, built, or otherwise, can be shared. While many sharing economy networks rely on trust and informal governance structures/rules, others make more use of bureaucratic elements. Supporters of the sharing economy claim it can reduce the risk that individuals take on, allow for scaling and reduce barriers to access, increase sustainability and productivity and decrease unnecessary consumption, and lead to more resilient communities. Some critics claim that benefits aren't guaranteed, and are dependent upon the motivations and methods associated with the initiative, and point to cooptation of these initiatives by corporate interests. Others claim that such a shift to sharing can lead to an unregulated market and unfair competition. Given the heterogeneity of sharing economy initiatives, it is important that they are criticized or applauded relative to the goals and context of each project.
