Cooperative Food Systems

Cooperative Food Systems builds on Cooperative Development Institute’s more than 20 years of work helping farmers, fishermen and consumers develop cooperatively structured food businesses and looks at how to change our food system through increased cooperation.

The whole idea of cooperatives is that we can do more together than on our own.
