Professor Scarpa graduated from Universita della Tuscia, Italy in 1988 with a Laurea (with Laude) in Agricultural Sciences. In 1989, after being awarded a grant for postgraduate education by the Parco Tecnologico della Regione Umbria, he moved to the University College of Wales, Aberystwyth, UK where he achieved an MSc in Environmental Impact Assessment.  In 1990 he was employed as "Ricercatore Universitario" by Universita della Tuscia and in 1993, following the award of a grant from the Fulbright Commission he enrolled in an M.A. in Agricultural Economics at the University of Wisconsin-Madison.  He moved on to complete a PhD in Forest Economics and Ecology under the supervision of Joe Buongiorno in the same University in 1999.  He has had academic positions in the UK, Australia and New Zealand where he is also Professor of Environmental Economics at the University of Waikato, Research Professor at CenSoC University of Technology Sydney and Adjunct Professor at the University of Western Australia.  In 2012, he joined the Gibson Institute at the School of Biological Sciences at Queens as Gibson Chair of Rural, Food and Environmental Economics.

Research Interests

Professor Scarpa has various research interests in the area of rural, food and environmental economics.  His methodological interest focuses on the theory and estimation of model of choice between discrete alternatives, and on dynamic models of forest management decision.  He has co-authored over 100 peer-reviewed papers, supervised over 15 PhD students and acted as a peer-reviewer for over sixty academic journals.
