Fruit and vegetable gleaning or field gleaning initiatives gather food left in fields after the primary harvest or food in fields where harvesting is not profitable. These initiatives can also collect food after farmers’ markets or farm stands close, or excess produce from farms, orchards, or packing houses. Urban gleaning or urban harvesting initiatives gather excess produce from registered fruit trees, community, school, and backyard gardens, or other urban agriculture sites. Most gleaning initiatives rely on volunteers to harvest, pick up, sort, and deliver fresh fruits and vegetables to food banks, food pantries, churches, mobile food pantries, and other community organizations that help distribute the produce to families with low incomes. Some participating farms use cull bins while harvesting to set aside non-marketable produce for donation1, 2.
Expected Beneficial Outcomes (Rated)
Increased consumption of healthy foods
Improved dietary habits
Other Potential Beneficial Outcomes
Reduced obesity rates
Increased food security
Evidence of Effectiveness
Fruit and vegetable gleaning initiatives are a suggested strategy to increase consumption of fruits and vegetables and improve eating habits, especially for families with low incomes1, 3, 4. Such initiatives are also a suggested strategy to prevent childhood obesity by increasing children’s access to fresh fruits and vegetables2. Gleaning initiatives may improve nutrition3 and support community food security5, although effects may be greater among larger scale or more intensive operations6. Food banks, food pantries, and meal programs can use fruit and vegetable gleaning initiatives to source and distribute fresh produce, which is a suggested strategy to reduce food insecurity and malnutrition among individuals and families receiving food assistance from food pantries and meal programs7, 8. Additional evidence is needed to confirm effects.
Every year, approximately 7% of planted fields in the US are not harvested, although this number varies widely, occasionally reaching as much as 50% for a particular crop9. Gleaning initiatives effectively harvest this produce; for example, in 2011, the US Department of Agriculture (USDA) gleaned 900,000 pounds for the Feds Feed Families Food Drive1.
Successful gleaning programs face several operational challenges, especially volunteer coordination and donated produce procurement and distribution. Several studies suggest methods to optimize gleaning schedules and maximize the volume of produce gathered7, 13, 14.
Impact on Disparities
The National Gleaning Project provides information on national and state laws and regulations pertaining to gleaning and food donation, an interactive map of gleaning and fresh food recovery organizations, and gleaning and food recovery reports and materials to support organizing and implementing gleaning programs across the country15.
A 2011 national survey of food banks reports 115 organizations with local agriculture programs, including 73 gleaning programs6. The Society of St. Andrew Gleaning Network, for example, gleans 15 to 20 million pounds of food annually and distributes gleaned produce in the contiguous 48 states and Washington DC16. The California Association of Food Banks’ Farm to Family program is the largest gleaning program in the nation; it distributes over 160 million pounds of produce annually to over 40 food banks17.
Statewide gleaning projects also glean millions of pounds of produce each year, for example, the Arkansas Gleaning Project18. Some states offer growers a tax credit for donations of excess produce to state-sponsored food banks, as in Arizona, California, Colorado, and Oregon9.
Regional non-profit organizations can run gleaning programs with food banks, churches, and other community partners. One example of such a partnership is FRESHFARM Markets which gleans throughout the Chesapeake Bay region19. Many local gleaning initiatives glean thousands of pounds of produce, as in Humboldt County, CA20. Gleaning initiatives can also supply fresh produce to schools in low income areas; for example, Ag Against Hunger supplies leafy greens and fresh fruit for school salad bars via the More Produce in Schools Program21.
Urban gleaning initiatives are underway in many cities, for example, San Francisco, CA22; San Jose, CA23; Washington DC24; Springfield, MO25; Grand Rapids, MI26; Salt Lake City, UT27; and Portland, OR28.
