Gleaning is the act of collecting leftover crops from farmers' fields after they have been commercially harvested or on fields where it is not economically profitable to harvest. It is a practice described in the Hebrew Bible that became a legally enforced entitlement of the poor in a number of Christian kingdoms.[1][2] Modern day "dumpster diving", when done for food or culinary ingredients, is seen as a similar form of food recovery.[3] Gleaning is also still used to provide nutritious harvested foods for those in need. In the United States, it is used due to the need for a national network to aid food recovery organizations. This is called the National Gleaning Project,[4] which was started by the Center for Agriculture and Food Systems at Vermont Law and Graduate School to aid those less fortunate much like the old Christian Kingdoms.
