Navin Ramankutty is Assistant Professor of Geography and the Earth System Science Program, and Tier II Canada Research Chair in Land Use and Land Cover Change at McGill University in Montreal. His broad research interests are in understanding the environmental consequences of human activities at continental to global scales. He studies the impacts of land use and land cover change on the structure and function of terrestrial ecosystems, and in turn, the effect of those impacts on the vital services such as food and freshwater that humans derive from ecosystems. More specifically, he uses a combination of global remote sensing and ground-based observations, statistical analysis, and numerical modeling approaches to study the impacts of agricultural expansion/intensification and tropical deforestation for the global carbon cycle, climate, food production, and fresh water flow. At McGill, he teaches courses in global land & water resources, global ecosystems, global environmental change, and Earth system modeling.
