Jerry Jacka is an associate professor in the department of anthropology at the University of Colorado Boulder. One aspect of his research examines the impacts of climate change on food security and social networks in highlands Papua New Guinea. Severe El Niño - Southern Oscillation (ENSO) events cause months-long droughts and frosts in the highlands that destroy subsistence food crops. Customarily, people utilized diverse gardening practices and long-distance migration to mitigate food insecurity. However, economic development and other social changes are challenging these adaptive strategies. Jacka works primarily with indigenous people, studying both sustainability and the limits to resilience in their social and ecological systems.
