"Basic responsibilities
The CCC Charter Act, as amended, aids producers through loans, purchases, payments, and other operations, and makes available materials and facilities required in the production and marketing of agricultural commodities. The CCC Charter Act also authorizes the sale of agricultural commodities to other government agencies and to foreign governments and the donation of food to domestic, foreign, or international relief agencies. CCC also assists in the development of new domestic and foreign markets and marketing facilities for agricultural commodities.
The CCC funds many programs that fall under multiple agencies within the USDA. Each CCC funded program helps achieve parts of both the CCC mission and the strategic plan of the agency under which the program falls. The CCC mission and strategic goals are achieved through the successful implementation of the following key programs areas:
Income Support and Disaster Assistance – Income support and disaster assistance programs provide financial assistance to protect farmers and ranchers from fluctuations in market conditions and unexpected natural or man-made disasters. Assistance is provided through income support programs, disaster assistance programs, and the Noninsured Crop Disaster Assistance Program (NAP). FSA is responsible for administering income support and disaster assistance programs.
Conservation – Supported by the Food, Conservation, and Energy Act of 2008 (2008 Farm Bill), conservation programs offer farmers and ranchers a variety of financial and economic incentives to conserve natural resources on the nation's privately owned farmlands. These programs focus on reducing erosion, protecting streams and rivers, restoring and establishing fish and wildlife habitats, and improving air quality through several conservation incentive payments, technical assistance, and cost-share programs. FSA and NRCS administer the CCC conservation programs.
Commodity Operations and Food Aid – FSA personnel handle the procurement, acquisition, storage, disposition, and distribution of commodities, and the administration of the United States Warehouse Act (USWA). These programs help achieve domestic farm program price support objectives, produce a uniform regulatory system for storing agricultural products, and ensure the timely provision of food products for domestic and international food assistance programs and market development programs.
Foreign Market Development – Expanding markets for agricultural products is critical to the long-term health and prosperity of the U.S. agricultural sector. With 95% of the world's population living outside the United States, future growth in demand for food and agricultural products will occur primarily in overseas markets. The CCC funds used in the market development programs play a critical role in helping to open new markets and in facilitating U.S. competitiveness and by doing so, help to secure a more prosperous future for American agriculture. Support for economic development and trade capacity building reinforces these efforts by helping developing countries to become economically stable and improve their prospects to participate in and benefit from expanding global trade in agricultural products. FAS administers the CCC foreign market development programs.
Export Credit – The CCC export credit guarantee and direct loan programs, administered by FAS in conjunction with FSA, provide payment guarantees for third party commercial financing and direct financing of U.S. agricultural exports. These programs facilitate exports to buyers in countries where credit is necessary to maintain or increase U.S. sales but where financing may not be available without CCC credit facilities."
