The grantees of the Community Food Projects Competitive Grants Program showed their strength by providing education, skills, food and resources to a diverse group of residents and food insecure communities across the nation.

Ten thousand farmers, many disadvantaged, were trained on sustainable agriculture and business management. Thousands of jobs and micro-businesses supporting the local food system were created, and customer bases for local agriculture were increased (3,000 + new buyers). Farm-to-cafeteria programs were created throughout the country providing markets for local farmers.

Nearly 19 million pounds of local, healthy food was distributed to over 2.5 million people, mostly in low-income neighborhoods across 39 states. With fast food available easily and cheaply for many Americans, the impact of providing healthy, fresh fruits and vegetables cannot be underestimated. Over 1.8 million children and youth in schools or summer programs ate fresh fruits and vegetables because of farm-to-cafeteria programs. Supplemental Nutrition Assistance Program (SNAP) and Women, Infants, and Children Program (WIC) recipients purchased local produce at farmers markets, and elder food recipients received seasonal fruit and vegetable shipments from local CSAs (Community Supported Agriculture). These healthy foods provide recipients with not only the nutrition to stay well, but also instill healthy eating habits that can last a lifetime. This becomes especially important for young children who may be at risk for obesity through the bad habits learned from a sedentary lifestyle.

Farmland depletion was delayed and local food production enhanced by the CFPs (Community Food Project) where almost 60,000 acres of land was farmed or preserved. Youth and urban gardeners learned to grow and prepare their own food through 2,500 community gardens and more than 9,000 garden plots.

Community food system capacity and infrastructure was enhanced through community food assessments, the formation of food policy councils and networks and the implementation of new policies. More than 50 million residents lived in the communities where these community-wide changes were made.

Results from the first five years of this food security program could be just a taste of the opportunities to come for improving the health, environment and economy of this country, when residents of almost every age are taught about healthy food supply and when they have access to delicious, abundant locally produced fruits, vegetables and meat.
