Available in PDF, EPUB and Kindle. Book excerpt: Provides and analyzes real examples of how structured decision making (SDM) can help solve complex problems involving natural resources. When faced with complicated, potentially controversial decisions that affect our environment, many resource management agencies have come to realize the value of structured decision making (SDM)—the systematic use of principles and tools of decision analysis. Few professionals, however, have extensive experience implementing SDM. Structured Decision Making provides key information to both current adopters of the method and those who are deploying it for the first time by demonstrating the formal use of decision analysis to support difficult, real-world natural resource management decisions. Drawing on case studies from multiple public agencies in the United States, Canada, Australia, and Mauritius, the editors present an overview of decision analysis, a classification of decision types, and a catalog of decision analysis methods. Dozens of detailed charts and maps help contextualize the material. These case studies examine a rich variety of topics, including • keeping forest birds free from disease • conserving imperiled freshwater mussels • managing water for oil sands mining • dealing with coastal wetlands in the face of sea-level rise • designing networks for prairie-dependent taxa • combatting invasive alpine shrubs • managing vernal pool habitats for obligate amphibian species • and much more Aimed at decision makers tackling natural resource challenges in government agencies around the world, as well as advanced undergraduate and graduate students preparing to work in natural resource management, Structured Decision Making shows how SDM can be implemented to achieve optimal outcomes that integrate social values and scientific understanding.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, maintaining the stock level of marine species and the sustainability of fisheries development have become critical issues in current scientific research due to over-harvest. The traditional method used to manage fisheries is the single species approach where policy is aimed at maximum sustainable yield. However, with the development of harvesting technology and increased competition to access stocks, the single species approach has been found incapable of dealing with problems of severe depletion of fish stocks. Studies show that when regulations are species specific and species are part of a multi-species fisheries, the catch levels of species are correlated which, in return, results in correlation of net returns across species. The single species approach ignores species correlation and should be modified to a multispecies approach which incorporates species correlation. This research applies portfolio analysis to multi-species fisheries, treats fish stocks as assets, and models the fishing firm faced with multiple targeting options, to determine the optimal targeting strategy. This method is applied to a New Zealand fishing firm operating within the Quota Management System (QMS). Species considered in this research are selected on the basis of two criteria: empirically these species have complete data; and, theoretically these species guarantee the covariance matrix is positive semi-definite so that the portfolio model has solution. The portfolio model is applied under two scenarios: first, the firm's optimal harvesting levels are strictly within its quota holdings; second, beyond its quota holdings by acquiring additional quota rights and/or paying deemed values on over-harvest. Efficient risk-return frontiers are generated that provide a combination of optimal strategies. Comparisons between the results and actual data are presented that allow us to draw conclusions about the benefit of implementing the portfolio approach into multi-species fisheries and the potential improvements the fishing firm can make to enhance fishing profit. It is found that the fishing firm should diversify its fishing portfolio by using external harvest rights, adjusting the holdings of some species and not harvesting other species.

Book excerpt: The overutilization of fish stocks, the overcapitalization of fisheries, the removal of associated benefits to society and growing concern over the conservation of marine biodiversity have resulted in a line of fisheries research that is multidisciplinary, dynamic and precautionary in approach. All the biological, ecological and economic factors need to be analysed if the forces regulating the dynamics of a fishery are to be appraised. This publication looks at the assumptions underlying the optimal allocation of renewable natural resources; lists the bioeconomic points of reference resulting from analysis of fisheries is supposed conditions of equilibrium; analysis bioeconomic models according to ecological interdependence factors (such as competition and predation) and technological factors (such as competition between fleets with different fishing capacity); offers a time-series analysis of fisheries and estimates the level of optimal effort; proposes mathematical models applied to bioeconomic analysis to support fisheries management plans; refutes the assumption of uniform resource distribution, incorporating a spatial dimension in fisheries dynamics analysis; and expounds basic elements of decision-making theory and criteria that reflect different attitudes to risk aversion in fisheries management.
