Graham MacDonald was a postdoctoral research associate with the Global Landscapes Initiative. MacDonald studies regional- to global-scale dimensions of agricultural land use and management. MacDonald’s interest in food systems is at the intersection between the biophysical and farm management context that underlies agricultural production and the socioeconomic factors that influence food consumption. Much of MacDonald’s current research addresses agricultural commodities trade. How does agricultural trade influence the distribution of resource use across regions? What is the role of international food trade in meeting dietary demand worldwide? MacDonald is increasingly interested in urban food systems, including methods to connect demand for food in cities with farming systems at different scales.
