Tenn. Code § 43-34-102
It is the intent and purpose of the state to encourage the conservation, protection, and responsible utilization of lands that are managed for purposes of agricultural production. It is recognized that these lands are finite, fragile, and valuable resources that contribute economically and socially to the well being of the state. It is also recognized that these lands are subject to change and conversion from agricultural production as a result of urban expansion, and similar land development measures. It is the policy of the state to provide a process for the recognition of lands dedicated to agricultural production and to assure an accurate understanding of the impacts of public policy decisions that might otherwise alter the capability of those lands to remain in agricultural production.
