Conservation strategies aimed at reducing threats to biodiversity can have significant implications for multiple sectors in a socioeconomic system, but these cobenefits are often poorly understood. For example, many of the threats to native species also impede agricultural production, yet agriculture is typically perceived as in competition with conservation objectives. Although a comprehensive, multiobjective decision analysis is usually beyond the scope and capacity of conservation decision makers, failing to incorporate key socioeconomic costs and benefits into conservation decision-making processes can result in missed opportunities for diversifying outcomes and creating cost-sharing multisectoral partnerships. We devised a straightforward and readily interpretable approach to incorporate cobenefits into a threat-management prioritization approach. We used it to analyze the agricultural cobenefits of implementing 9 invasive animal management strategies designed to ensure the persistence of 148 threatened species across Australia's Lake Eyre Basin over 50 years. A structured elicitation process with 24 participants (scientists, land managers, agriculturalists, and other stakeholders) was used to collect information on each strategy, including costs, technical and social feasibility, benefits to native threatened species, and cobenefits to agricultural production systems. The costs of targeted invasive animal management to save threatened species across the basin (AU$33 million/year) outweighed the overall benefits to the agricultural industry (estimated AU$226 million/year). The return on investment for these management strategies varied substantially when agricultural cobenefits were considered alongside threatened species benefits and showed synergies and challenges. Our approach demonstrates the value of incorporating cobenefits of conservation actions into cost-effectiveness analyses to guide potential investment and partnerships and to diversify implementation pathways.

快速评估协同效益以推进威胁管理联盟

旨在减少对生物多样性威胁的保护战略可能对社会经济系统中的多个部门产生重大影响，但这些共同利益往往知之甚少。例如，对本地物种的许多威胁也阻碍了农业生产，但农业通常被视为与保护目标相竞争。虽然全面的、多目标的决策分析通常超出了保护决策者的范围和能力，但未能将关键的社会经济成本和收益纳入保护决策过程，可能会导致错失实现结果多样化和建立成本分担的多部门伙伴关系的机会。我们设计了一种直接且易于解释的方法，将协同效益纳入威胁管理优先级排序方法。我们用它来分析实施 9 项侵入性动物管理策略的农业协同效益，这些策略旨在确保澳大利亚艾尔湖流域 50 年来 148 种受威胁物种的持续存在。一个有 24 名参与者（科学家、土地管理者、农业学家和其他利益相关者）的结构化启发过程被用来收集关于每项战略的信息，包括成本、技术和社会可行性、对本地受威胁物种的好处以及对农业生产系统的协同效益。为拯救整个流域受威胁物种而进行的有针对性的入侵动物管理成本（3300 万澳元/年）超过了农业的总体收益（估计为 2.26 亿澳元/年）。当将农业协同效益与受威胁物种的利益一起考虑并显示出协同作用和挑战时，这些管理策略的投资回报会有很大差异。我们的方法展示了将保护行动的协同效益纳入成本效益分析以指导潜在投资和合作伙伴关系并使实施途径多样化的价值。
