The integration into global and local agri-food value chains requires farmers, food processors and grocery retailers to develop and maintain close and sustainable business relationships with buyers and suppliers. While agricultural value chains have been promoted for decades, more attention is needed on how to enable economic agents to develop trust and lasting relationships within value chains. Using qualitative and quantitative empirical results, "Agri-food Chain Relationships" provides an overview of existing relationship economics and management, offering an insight into the sustainability of current agribusiness relationships and discussing how these may be improved.
