Institute of Food and Agricultural Sciences - University of Florida
The University of Florida’s Institute of Food and Agricultural Sciences (UF/IFAS) is a federal-state-county partnership dedicated to developing knowledge in agriculture, human and natural resources, and the life sciences, and enhancing and sustaining the quality of human life by making that information accessible. While extending into every community of the state, UF/IFAS has developed an international reputation for its accomplishments in teaching, research and extension. Because of this mission and the diversity of Florida’s climate and agricultural commodities, IFAS has facilities located throughout Florida.
IFAS provides research and development for Florida’s agricultural, natural resources and related food industries, which in 2010 made value-added contributions of $108.7 billion to the gross domestic product of the state economy.
