Description

Farm to school programs connect schools with nearby farms to incorporate locally-grown foods into school breakfasts, lunches, and snacks. Local food can be delivered via salad bars, fruit and vegetable bars, breakfast or lunch entrees, or taste testing or snack programs. Comprehensive farm to school programs have several additional components, including: school gardens, nutrition and agriculture education, recycling, composting, and food waste reduction efforts, as well as enrichment activities such as cooking classes, farm field trips, or classroom visits by food producers. Schools can implement farm to school programs independently; state and local policies can also support and encourage farm to school programming. 

Expected Beneficial Outcomes

Increased willingness to try fruits & vegetables
Increased fruit & vegetable consumption
Improved nutrition
Improved local economy

Evidence of Effectiveness

There is some evidence that farm to school programs increase knowledge about, willingness to try, and consumption of fruits and vegetables among school children (Jones 2015, Izumi 2015, Yoder 2014, Moss 2013, Slusser 2007Evans 2012aScherr 2013Wang 2010a, UNC-F2S, Evers 2015). Farm to school programs are a recommended strategy to improve dietary habits and nutrition (USDA-Ritchie 2011CDC-Fruits and vegetables 2011CDC-Dietz testimony 2009TFAH-Levi 2014, Berlin 2013). However, additional evidence is needed to confirm effects.

Research suggests that more years of farm to school programming are associated with greater increases in fruit and vegetable consumption than fewer years (Yoder 2014), and continued exposure to farm to school programming may be needed to sustain positive effects on vegetable consumption (Evers 2015). Farm to school programs that include salad bars can increase children’s fruit and vegetable consumption and can lower their saturated fat intake (Slusser 2007). Nutrition education interventions that include school gardening components increase children’s willingness to try and knowledge about fruit and vegetables more than nutrition education alone (Morgan 2010).

Rigorous research on farm to school programs alone is limited; however, assessments of school gardens, salad bars, and multi-component school interventions that are similar to farm to school programs show positive effects (Taylor 2013). Multi-component interventions that last for at least one year, increase exposure to fruits and vegetables school-wide, and integrate with existing curriculum increase children’s fruit and vegetable consumption. Such interventions that also include encouragement from school food service staff, peer leadership, teacher training, and parental involvement have shown the greatest effects (Knai 2006French 2003Howerton 2007). Multi-component interventions that combine daily activities with special school-wide events can be more effective than daily activities alone (Perry 2004).

Surveys of food service professionals in the Upper Midwest and Northeast US suggest these professionals support farm to school programs because kids like the food and eat fruits and vegetables instead of throwing them away (Izumi 2010). Surveys also suggest that food service directors are motivated to participate in farm to school programs to support local farmers and local economies (Colasanti 2012), though many have concerns about food safety and distribution challenges (Pinard 2013). Surveys of growers in Mississippi and Vermont suggest that producers are motivated to sell produce to local schools both to increase profits and to improve community nutrition and increase students’ awareness of agricultural practices (Rosenberg 2014, Conner 2012). After exposure to farm to school programs, parental surveys suggest that children request more fruits and vegetables at home (Jones 2015).

School lunch recall surveys have been validated as an effective and efficient tool for assessing school lunch intake (Paxton 2011). 

Implementation

United States

According to the national farm to school website, all 50 states have operational programs; programs are located in both rural and urban communities (National Farm to School). According to the US Department of Agriculture Census, 42% of school districts surveyed have an existing farm to school program, that is over 42,500 schools participating in farm to school activities (USDA-F2S Census). As of October 31, 2014, 46 states had proposed or enacted legislation regarding farm to school programs (CAFS-F2S legislation 2015, NCSL Winterfeld-Obesity prevention 2014). The Farm to School Act of 2015 has been introduced in Congress as part of the process for the Child Nutrition Act Reauthorization (National Farm to School).

Program evaluations have been conducted in many states, including Wisconsin, California, Connecticut, Florida, Maine, New York, North Carolina, Oregon, and Vermont (Yoder 2014, VT FEED-VT F2S, UNC-F2S, Azuma 2001).

Case studies of farm to school programs are also available from efforts in California, Colorado, Florida, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Montana, New Hampshire, New Mexico, New York, North Carolina, Oregon, Pennsylvania, Vermont, Washington, and Wisconsin (National Farm to School). Many university extension programs house and support farm to school programs, for example Ohio State University Extension (OSU Ext-F2S), University of Minnesota Extension (UMN Ext-F2S), and University of Illinois Extension (UIL Ext-F2S).

Wisconsin

As of 2015, there were farm to school activities serving local food in over 235 school districts across the state (WI F2S, WI DPI-F2S). The 2009 Wisconsin Act 293 supports school-based initiatives to combat childhood obesity by connecting K-12 schools with healthy locally grown produce (WI Act 293). 

In 2013, the Transform Wisconsin Coalition awarded impact grants to 26 communities across the state to address one of three key areas, including strengthening farm to school programs so Wisconsin students have access to fresh fruits and vegetables (Transform Wisconsin).

There are several resources available to assist Wisconsin communities implementing farm to school programs (UW CIAS-F2S Toolkits, WI DPI-Davidson 2011, WI F2S, WI DPI-F2S, Fifth Season Co-op).
