Professor Le Heron is an economic geographer whose research concerns land-based production, agribusiness and food and commodity chains. He has made a major contribution to our understanding of agro-commodity systems, in the process consolidating this sub-field within the international field of economic geography. His work integrates a political economic perspective on land-based industries with an analysis of the flows across space as they are shaped by the forces of globalisation and regulation. As such he has played an important role in elucidating those activities that have helped shape New Zealand’s place in the global economy. His work has had considerable international impact and is widely cited.
