Publication: letter on Ivory trade policy in Science by Solomon Hsiang

Alongside a large interdisciplinary team, Sol coauthored a letter today in Science today explaining that recommendations to limit trade in legal ivory are based on evidence-based research. This was a response to an earlier article by Biggs et al. arguing that recommendations to limit trade were based on arbitrary values. We also point out that transparency in international negotiations are an important element of the process, in contrast to the recommendation by Biggs et al. to speed up international decision-making by negotiating international trade in ivory behind closed doors.
