As USDA celebrates 150 years of serving American agriculture and rural communities, it is important to remember the enormous contribution of the Cooperative Extension Service, a three-way partnership between USDA and our state and county partners that forms a nationwide network of expertise. These experts work with Americans on issues that relate to a wide range of topics including: agriculture, natural resource management, nutrition, youth development, community empowerment, household and family budgeting, and disaster assistance, among others.
