Lone Mountain Fellow, Research Fellow

PERC Research Fellow Michael ’t Sas-Rolfes is a sustainability economist, with unique experience and understanding of the role of markets for biodiversity conservation. He is a 2023 Lone Mountain Fellow as well as a research associate at the University of Oxford with his research focused on understanding the complexities of both legal and illegal markets for wildlife products, notable those of charismatic endangered species such as rhinos, elephants, big cats, and bears. As part of his current interdisciplinary doctoral research in the Oxford Martin Program on Wildlife Trade, Michael is investigating methods for gaining a predictive understanding of wildlife trade dynamics, specifically using scenario analysis and participatory modeling to try and resolve questions about appropriate policies toward trade in endangered species.

For the past 25 years, he has been actively involved in various private conservation initiatives, starting as a financial manager of a private game reserve in South Africa. Mike conducted pioneering research into the role of private markets for wildlife conservation in Southern Africa and worked with Francis Vorhies in setting up Eco Plus, an innovative consultancy on business, economics, and the environment. His consulting experience includes work on issues as varied as energy policy, environmental impact assessments, trans-frontier conservation areas, wildlife trade policy, and institutional reform in protected area management.

He has written extensively on various conservation issues, especially relating to trade in endangered species, and has been involved with teaching and supervision of students. Mike has also worked and published with several think tanks, including the Free Market Foundation (South Africa), the Institute of Economic Affairs Environment Unit (UK), the International Policy Network (UK), and the Property and Environment Research Center (PERC), where he was a 2011 Lone Mountain Fellow.
