Speaker: David Kanter, associate professor of environmental studies, New York University

Nutrient pollution is one of the most important environmental and human health threats society faces. Policy efforts to address it, particularly from its dominant source, agriculture, have fallen flat. Kanter argues that a new approach to national and global nutrient pollution governance is essential: one that centers nutrients in several international environmental agreements and expands the policy horizon beyond the farm to include actors across the agri-food system. Such an approach would not just enable more effective environmental policy, it would make the United States and others more economically resilient to global price shocks in an increasingly volatile world.
