Gleaning: An Ancient Solution to Modern Food Loss
Discover how gleaning bridges food waste, hunger relief, and community action from field to table.

Each year, billions of pounds of food never make it from field to fork, lost to harvesting inefficiencies, market standards, and logistical barriers. Yet a centuries-old solution—gleaning—offers a bridge between food waste and food need. Rooted in tradition and reinvented for today, gleaning mobilizes communities to rescue surplus produce, nourish the hungry, and address the pressing challenges of modern food systems.
What Is Gleaning?
Gleaning is the practice of gathering leftover crops from fields after commercial harvest or from fields where it is not economically profitable to harvest. This can include produce left behind because of labor shortages, cosmetic imperfections, market rejection, or simple overabundance. While its origins are ancient, gleaning has found new urgency as a practical and symbolic solution to food waste and insecurity.
- Traditional Roots: References to gleaning appear in ancient literature and religious texts, where landowners left portions of their harvest for the poor.
- Modern Practice: Today, volunteers, non-profits, and occasionally municipal programs coordinate efforts with farmers to collect surplus food, delivering it to food banks, pantries, and shelters.
- Broad Scope: Gleaning encompasses farms, community gardens, home fruit trees, and sometimes even overstocked markets or institutions.
Why Gleaning Matters
The scale of food waste is staggering, with the EPA estimating that nearly one-third of food produced in the U.S. is wasted, and approximately 24% of landfill material is food waste. Farms alone account for around 21% of this loss, often due to stringent cosmetic standards or mismatches between supply and market demand. Yet, simultaneously, hunger persists: millions of people lack consistent access to nutritious food.
- Gleaning diverts perfectly edible, nutritious food from going to waste.
- It connects surplus produce with communities and individuals facing food insecurity.
- Gleaning mitigates the environmental impact of decomposing food, which can emit methane, a potent greenhouse gas.
The Twofold Benefits of Gleaning
According to research and gleaning organizations, the practice delivers dual impacts:
- Reduces food waste by capturing crops left in fields, thus lowering landfill contributions and greenhouse gas emissions.
- Improves nutrition for food-insecure populations by offering access to fresh fruits and vegetables, items often lacking in food pantries dominated by canned and packaged goods.
How Gleaning Works
Though its essence is simple—rescue unused food and deliver it to the needy—gleaning can take on various organizational forms, from small, grassroots efforts to large, coordinated campaigns.
Step-by-Step Breakdown of the Gleaning Process
- Identify Surplus: Farmers or landowners determine that a crop is remaining after main market harvests, often because it doesn’t meet size, shape, or cosmetic standards.
- Partner Outreach: Nonprofits or gleaning programs connect with willing donors and confirm date, location, and logistics.
- Volunteer Mobilization: Programs recruit and organize volunteers, providing necessary training and coordinating transportation.
- Harvesting: Volunteers enter the fields and collect usable produce, following food safety and handling protocols.
- Sorting and Distribution: The harvested food is sorted, cleaned, and packed. It is then delivered to food banks, food pantries, community kitchens, or shelters.
Who Organizes Gleaning?
Most gleaning is facilitated by non-profit organizations specializing in food rescue, sometimes in collaboration with farmers, municipal agencies, or faith-based groups.
- Society of St. Andrew (SoSA): One of the largest U.S. gleaning networks, SoSA partners with farmers nationwide, mobilizing thousands of volunteers annually. Their efforts yield millions of pounds of rescued produce each year, which is distributed through food banks and hunger relief networks.
- Local Food Banks: Many food banks have dedicated gleaning programs or teams that coordinate with area growers and volunteers.
- Grassroots Initiatives: Smaller groups, community gardens, and churches often organize gleaning days, inviting families and individuals to participate directly.
- Municipal Programs: A growing number of cities have built urban gleaning into their sustainability or public health initiatives, especially as food insecurity becomes increasingly urbanized.
Why Surplus Crops Exist
Surplus and “unmarketable” crops occur for several reasons:
- Cosmetic Standards: Supermarket contracts demand uniform size, shape, and external appearance, leaving misshapen but perfectly edible produce behind.
- Market Fluctuations: Changes in consumer demand or order cancellations leave excess produce on the farm.
- Labor Shortages: Insufficient labor can make full harvests infeasible.
- Overproduction: Farmers often plant extra as insurance against weather and pests; if all goes well, there may be more than the market requires.
- Weather Events: Crops may be damaged, rained on, or ripen all at once, outpacing picking capacity or market demand.
Modern Gleaning Around the World
While gleaning is a global phenomenon, its organization and scale can differ widely depending on cultural traditions, agricultural landscapes, and food security needs.
United States
- Scale: Most U.S. gleaning is community-based or led by nonprofits like Society of St. Andrew, as opposed to having government-led structures.
- Focus: Efforts revolve around farms, orchards, local produce growers, and occasionally urban gardens.
- Volunteer-Driven: Programs rely on local volunteers, often churches, schools, or neighborhood groups.
United Kingdom
- Centralized Networks: The UK Gleaning Network runs large, coordinated operations, regularly returning to partner farms and organizing national “gleaning days.”
- Logistics: Food is delivered to hunger-relief charities and redistributed regionally, often involving a transportation infrastructure.
Urban Gleaning
- Definition: City-run or nonprofit urban gleaning programs harvest food from community gardens, parks, public fruit trees, and sometimes households.
- Distribution: Gleaned urban produce is sent to local food banks, soup kitchens, shelters, or directly to those in need.
- Broader Impact: Urban gleaning not only supplies fresh produce but draws attention to food systems within city environments, bridging food justice and sustainability efforts.
Case Studies and Success Stories
Society of St. Andrew (U.S.)
The Society of St. Andrew has coordinated gleaning projects for over 35 years, engaging with farmers and volunteers across the United States. Annually, their efforts prevent over 30 million pounds of food from being wasted, supplying fresh produce to food banks and pantries nationwide. Alongside gleaning, their Harvest of Hope and Potato and Produce Project foster community through collective action in food rescue and distribution.
North Carolina Blueberry Gleaning Project
A collaborative project in North Carolina united extension agents, local farms, and community organizations to glean surplus blueberries for regional food pantries. Participants not only diverted thousands of pounds of berries from waste but also built awareness around local food systems and fostered new farm-community relationships.
Boise Urban Gleaning (Idaho)
Peaceful Belly Farm outside Boise partners with neighborhood groups to rescue leftover crops at the end of each harvest, distributing tens of thousands of pounds of produce to local agencies and individuals in need.
How to Start or Join a Gleaning Effort
If you’re inspired to get involved, here’s an effective pathway:
- Connect with local food banks or gleaning organizations. Many maintain regular volunteer programs.
- Reach out to area farmers or community gardens to gauge interest in gleaning partnerships.
- Recruit friends, neighbors, or community groups. The process is often more efficient and enjoyable in teams.
- Access toolkits, such as the USDA “Let’s Glean” toolkit, which provides extensive guidance on organizing a safe and efficient gleaning operation, from volunteer management to food safety best practices.
Gleaning’s Lasting Impact
Beyond simply salvaging food, gleaning plays a pivotal role in building community resilience and food system awareness:
- Education: Volunteers often gain firsthand knowledge about agriculture, food waste, and the complex journey from field to plate.
- Community Engagement: Gleaning unites diverse groups in a shared mission, fostering empathy across social and economic divides.
- Sustainability: Each gleaned crate represents food that won’t contribute to methane emissions in landfills, decreasing agriculture’s carbon footprint.
Challenges and Opportunities
While impactful, gleaning alone cannot solve the root systemic issues behind food waste and hunger. Barriers include:
- Logistical Hurdles: Timely coordination among farmers, volunteers, and distribution sites is essential but challenging, especially for perishable crops.
- Labor Intensiveness: Gleaning is physically demanding and time-sensitive; volunteer shortages can limit impact.
- Liability Concerns: Some farmers worry about legal risks from donated produce, though the U.S. Good Samaritan Food Donation Act provides liability protection.
- Systemic Overproduction: Gleaning is a stopgap; long-term change depends on market reform, including developing secondary markets for “imperfect” produce.
