Introduction and overview: the greenway movement, uses and potentials of greenways

This special greenways issue has three overlapping purposes. First, to introduce the greenway movement through the best available and current literature on greenway research, planning and implementation. Second, to examine this and earlier greenways literature so that we can offer a clearer and perhaps a more comprehensive definition of greenways. Third, to organize the papers into logical groups to facilitate a better understanding of the greenways movement.
