Cost-effective priorities for global mammal conservation

摘要: Global biodiversity priority setting underpins the strategic allocation of conservation funds. In identifying first comprehensive set global areas for mammals, Ceballos et al. [Ceballos G, Ehrlich PR, Soberon J, Salazar I, Fay JP (2005) Science 309:603–607] found much potential conflict between and agricultural human activity. This is not surprising because, like other priority-setting approaches, they priorities without socioeconomic objectives. Here we present a framework that seeks to minimize conflicts opportunity costs meeting goals. We use it derive new investment in mammal based on (i) cost importance, (ii) current levels international funding, (iii) degree threat. Our approach achieves same outcomes as al.'s while reducing with activity by up 50%. uncover shortfalls funds many threatened areas, highlighting challenge.
