A Dynamic and Stochastic Perspective on the Role of Time in Range Management

Abstract

This paper uses a new ecological-economic approach to analyze the role of time in range management in a dynamic and stochastic setting. We first construct a theoretical model of a parcel of rangeland in which time restrictions are used to manage the land. We then show how the dynamic and the stochastic properties of this rangeland can be used to construct two managerial objectives that are ecologically and economically meaningful. Finally, using these two objectives, we discuss an approach to range management in which the manager has two interrelated goals. This manager maximizes the profits from range operations and (s)he also takes steps to move the rangeland away from the least desirable state of existence.

On the choice of the optimal temporal control in renewable resource management

“…In addition to short duration grazing, grazing systems such as the Merrill three herd and four pasture system and rest rotation grazing also have spatial and temporal control aspects to them. For more on this and related issues, seeBatabyal (2001a, b),Batabyal et al (2001a-c),Batabyal and Yoo (2001), andHolechek et al (2001).3 However, we stress that our analysis applies equally well to fisheries.…”
