A 2018 Horizon Scan of Emerging Issues for Global Conservation and Biological Diversity

International audience; This is our ninth annual horizon scan to identify emerging issues that we believe could affect global biological diversity, natural capital and ecosystem services, and conservation efforts. Our diverse and international team, with expertise in horizon scanning, science communication, as well as conservation science, practice, and policy, reviewed 117 potential issues. We identified the 15 that may have the greatest positive or negative effects but are not yet well recognised by the global conservation community. Themes among these topics include new mechanisms driving the emergence and geographic expansion of diseases, innovative biotechnologies, reassessments of global change, and the development of strategic infrastructure to facilitate global economic priorities., This is the ninth such annual horizon scan., Twenty-four experts in conservation research and practice, ecology, economics, policy, and science communication identified 15 topics following a wide consultation. They followed a Delphi like process to score and identify the most important., The issues highlighted span a wide range of fields and include thiamine deficiency in wild animals, the geographic expansion of chronic wasting disease, genetic control of invasive mammal populations and the effect of culturomics on conservation science, policy and action.
