Donors, NGOs, and governments increasingly invest in campaigns to reduce consumer demand for wildlife products in an attempt to prevent the decline of overexploited and poached species. We provide a novel framework to aid these investment decisions based on a demand reduction campaign's return on investment compared to antipoaching law enforcement. A resulting decision rule shows that the relative effectiveness of demand reduction compared to increased enforcement depends entirely on social and economic uncertainties rather than ecological ones. Illustrative case studies on bushmeat and ivory reveal that campaigning to reduce demand may be more cost‐effective than antipoaching enforcement if demand reduction campaigns drive modest price reductions. The outputs from this framework can link targeted monitoring of wildlife product prices to management decisions that protect species threatened by harvest and trade.

加强反偷猎执法或减少对野生动植物产品的需求？指导战略性保护投资的框架

捐助者，非政府组织和政府越来越多地投资于减少消费者对野生动植物产品需求的运动，以防止过度开发和偷猎物种的减少。我们提供了一个新颖的框架，可以根据减少需求运动与反偷猎法执法相比的投资回报来协助这些投资决策。最终的决策规则表明，与增加执法相比，减少需求的相对有效性完全取决于社会和经济不确定性，而不是生态方面的不确定性。关于食用森林猎物和象牙的示例性案例研究表明，减少需求的运动可能比反偷猎执法更具成本效益，如果减少需求的运动能够适度地降低价格。
