Spillovers from Conservation Programs
Conservation programs have increased significantly, as has the evaluation of their impacts. However, the evaluation of their potential impacts beyond program borders has been scarce. Such spillovers can significantly reduce or increase net impacts. In this review, we discuss how conservation programs might affect outcomes beyond their borders and present some evidence of when they have or have not. We focus on five major channels by which spillovers can arise: (1) input reallocation; (2) market prices; (3) learning; (4) nonpecuniary motivations; and (5) ecological-physical links.
