Optimising harvest strategies over multiple objectives and stakeholder preferences

摘要: Abstract Natural resource management has long recognised that the multi-objective nature of is important, but struggled to operationalise this into quantitative, measurable objectives for functional use in management. Operationalising broader ecological and social been particularly problematic. In fisheries management, focus mainly on target species sustainability and, past few decades, profitability. However, now essential as have become complex social-ecological-systems. Policy legislation demand a move towards quantitative approaches reconciling multiple operationalising these within harvest strategies. We present non-commensurable-unit approach, via multi-indicator value function with explicit objective preference weights. simulation set Total Allowable Catches (TACs) three main groups reef line fishery Australia's Great Barrier Reef. Our method enables stakeholders consider richer range tradeoffs than possible bio-economic models. Moreover, it allows formal evaluation performance across alternative stakeholder group preferences, providing an impartial way obtain overall optimum TAC. The requires extensive data indicators associated each be quantitatively defensibly defined. Thus, our approach provides pathway forward forces managers confront requirements.
