This part is generally descriptive in nature. Its ma.jar purpose is to describe and summarize various state legislative material outside of New York which is concerned with the problem of preserving farmland from urban and speculative pressures. Such a summary can be of substantial aid to any person concerned with the possible approaches to farmland preservation in New York. One of the major problems associated with a farmland preservation program in any state is that of deciding what land should be affected by the program. An equally serious companion problem is how to define or specify the desirable land once it has been identified. For this reason, much of this discussion of state legislation will focus on the parts of the various state laws that either attempt to define eligible lands or establish criteria to be used in such decisions. It is difficult to classify state legislation in this field into a few broad categories, mainly because the different states have approached the problem in a multitude of ways. It is possible, however, to come up with some type of crude classification. This author prefers to place the various existing legislative approaches to the problem into the following four general categories: General preferential assessment, tax deferral, exclusive agricultural zoning, and restrictive agreements.
