This paper explains the concepts of fuzzy set theory and applies them to the problem of allocating public forest land on Vancouver Island among competing land uses. Two principal sources of fuzziness are identified: those related to uncertainty in classification (specification of management objectives) and those related to uncertainty concerning how actions affect objectives (imprecise technical coefficients). Comparing the results of classical and fuzzy decision models enables determination of which approach provides improved results, and which is more consistent with the political decision-making process in British Columbia.
"Land allocation use specialization is a forest management strategy designed to accommodate the wide array of values present on the forested landscape, having the potential to enhance both environmental and industrial uses of the forest. The details of such a strategy, however, are not fixed, being case specific. The challenge is to define the basis for zoning considering the multiplicity of values expected from each particular forestland base. Therefore, this work explores the implications of different zoning approaches for land allocation in the Prince George Forest District of central British Columbia, Canada. To do so, three objectives were set: a) evaluate the consequences of different zoning strategies on a specific forestland base; b) examine the effects of different area proportions among categories on the land use allocation; and c) explore how expected future climate change may affect land use allocation in the study area. The methodology consisted of defining the basic values expected by stakeholders from the forest land base and combining them using three different zoning approaches: three-zone, four-zone and multiple-zone. Results show that the zoning approach has major influences on the results, increasing spatial distribution and fragmentation with an increase in the number of zones. Furthermore, the increase in target area of a specific category results in its greater distribution over the landscape and better representation of the variety of landscapes found in the study area. Finally, climate change predictions can be proactively incorporated in land use plans, creating more robust land use plants. The methodology employed in this work enables the amalgamation of multiple sources of information to define forest values, it is flexible and it also provides spatially explicit allocation maps easy to assimilate."--P. ii.
The goal of Kangas, Kangas and Kurttila's Decision Support for Forest Management is to provide students and researchers with a toolbox of methods for approaching the different planning situations that may arise in practice. It draws together a wide range of methods used in planning forest management regimes and presents a systematic overview of current methodological approaches. While earlier books concerning forest planning have tended to focus on linear programming, economic aspects, or specific multi-criteria decision aid tools, this book provides a much broader range of tools to meet a variety of planning situations. The methods themselves cover a range of decision situations – from cases involving single decision makers, through group decision making, to participatory planning. They include traditional decision support tools, from optimization to utility functions, as well as methods that are just gaining ground in forest planning – such as problem structuring methods and social choice theory. Including examples which illustrate the application of each technique to specific management planning problems, the book offers an invaluable resource for both researchers and advanced students specializing in management and planning issues relating to forestry.
Decision Methods for Forest Resource Management focuses on decision making for forests that are managed for both ecological and economic objectives. The essential modern decision methods used in the scientific management of forests are described using basic algebra, computer spreadsheets, and numerous examples and applications. Balanced treatment is given throughout the book to the ecological and economic impacts of alternative management decisions in both even-aged and uneven-aged forests. In-depth coverage of both ecological and economic issues Hands-on examples with Excel spreadsheets; electronic versions available on the authors' website Many related exercises with solutions Instructor's Manual available upon request
One of the more pressing resource management problems in British Columbia is the allocation of forest land between competing uses. This study examines the technical evaluation of alternative uses in environmental impact assessment (EIA) to reach land allocation decisions. A review of evaluative techniques commonly used by provincial agencies to assess resource use was conducted, along with a review of the use of cost-benefit analysis. A case study of the West Coast Trail is used to apply the methods.
