As the Pennsylvania farmland preservation program enters its 30th year, this is the first formal analysis of its economic impact. The value of such an analysis is to 6 estimate the benefits to the agricultural industry, the state’s economy, and the counties where the preserved farms are located. To assess the contribution of the state/county farmland preservation program to the Pennsylvania state economy, the study estimates a multiplier effect and also estimates the annual contribution of preserved farms to the agricultural economy and the general economy of the state.
