Hahn publishes research on ecological and institutional economics focusing on ecosystem services, adaptive governance, social learning, sustainability transformations, and green economy. At present, he has four research project grants: 1) Institutional analysis of Ecological Compensation as an instrument for ensuring No Net Loss of biodiversity and ecosystem services (Formas); 2) Mistra Financial Systems: Putting financial systems to work for sustainability, where he is a leader and member of the program management group; 3) Effective and equitable institutional arrangements for financing and safeguarding biodiversity (Formas); and 4) BiodivERsA3: GreenFutureForest, where he is the leader on insurance value of ecosystems.
Hahn is also coordinating lead author for the European and Central Asian Regional Assessment of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES).
Hahn holds a PhD from the Swedish University of Agricultural Sciences, where he studied property rights of the indigenous Sami people, ethics, and conflict resolution. With a background in agricultural economics, he has explored interdisciplinary science, from social sciences to ecology. Presently, his work is mostly transdisciplinary. Previously, Hahn was a full-time teacher and the director of studies at SRC, but now focuses more on research.
In 2013, Hahn worked half-time co-authoring a report, commissioned by the Swedish government, on the value of ecosystem services. He is currently engaged in dialogue seminars within the CBD (Convention on Biological Diversity) and with IPBES.
Hahn serves as a board member of Sveaskog AB, the largest forest owner in Europe, and as a board member of the Swedish Nuclear Waste Fund. He also serves as expert in governmental investigations on climate economy and on ecological compensation. He is also a member of a think tank Global Utmaning (Global Challenge), and recently participated in a pre-study on green economy for Mistra, the Swedish foundation for strategic environmental research. This report was launched in 2015 and it was broadcasted by national television.
Hahn regularly gives presentations about his research to various Swedish parliamentary committees, the Swedish Environmental Protection Board, the Swedish Board of Agriculture, and decision-makers in the private sector, including NGOs.
Hahn collaborates with other departments at SU on teaching and research. He has helped catalyze the Faculty of Social Sciences to instigate a new topic for graduate studies: environmental social science, which will promote interdisciplinary research careers. In 2015 Hahn had some of his research featured by Stockholm University.
