Income inequality can be both a driver and a consequence of food systems. As a driver, inequality can play into food production systems, food environments, and individual factors that influence access to food. However, food systems can also contribute to income inequality through skewed distribution of the value of food across the supply chain (producers assume more risk and less of the revenue than distributors or retailers).
