Historically, the U.S. Government has played an important role in national and regional agricultural production. At the national level, the Government uses production control programs, price supports, and loans to increase and stabilize farm commodity prices and also invests in research, development, and extension in promoting production supply. On the regional level, it has invested in various development projects such as the installation of irrigation to promote regional agricultural production, or to regulate regional land use to avoid permanent depletion of resources.
