Purchase of development rights (PDR) programs enjoy public as well as farmer support. PDR refers to a land use control initiative that intends to limit the use of agricultural land to farm production by making it unavailable for development. Public support for PDR is explained by the efforts of non-farm residents to preserve the rural atmosphere of the area. Farmer support, on the other hand, is dictated by market forces, such that growth in the number of farms increases farmer support of PDR.
