Climate, Food, and Nutrition
Climate change is impacting our global food system, and, in turn, changes to food supply and quality may affect our health.
Lewis Ziska, Ph.D., is a plant physiologist formerly with the U.S. Department of Agriculture's Agricultural Research Service. He has published over 100 peer-reviewed research articles related to climate change and rising carbon dioxide that address: agriculture and food security; invasive species; and plant biology and public health. Ziska was a contributor to the 2014 International Panel on Climate Change report (Food Security Chapter); the 2014 National Climate Assessment (Public Health Chapter); and The Impacts of Climate Change on Human Health in the United States: A Scientific Assessment.
Climate Change and Mental Health
Changes to our environment affect our everyday life, perceptions, and experiences. They can be gradual changes in temperature or precipitation as well as more abrupt changes, like extreme weather events. Both impact the way we think and feel. These effects of global climate change on mental health and well-being are a critical part to addressing the climate crisis and responding to its overall health impacts.
Susan D. Clayton, Ph.D., is the Whitmore-Williams Professor of Psychology at the College of Wooster in Ohio. She has a Ph.D. in social psychology from Yale University. Clayton’s research examines humans’ knowledge and attitudes about the environment, the effects of climate change on mental health, and issues of social and environmental justice. She has written extensively about psychology and climate change. Clayton serves on the editorial boards of the Journal of Environmental Psychology, Sustainability, and the Journal of Zoological and Botanical Gardens, and is the editor of the Cambridge Elements series in Applied Social Psychology. She is a lead author on the forthcoming Sixth Assessment Report of the Intergovernmental Panel on Climate Change.
Joshua C. Morganstein, Ph.D., is Associate Professor and Assistant Chair in the Department of Psychiatry and Assistant Director at the Center for the Study of Traumatic Stress (CSTS) in the Uniformed Services University of the Health Sciences in Bethesda, Maryland.

Wildfires and Indigenous Populations
Prompted by a changing climate, record heat, dry vegetation, and low humidity, unprecedented wildfires have burned throughout the world. Wildfires and exposure to wildfire smoke pose multiple human health threats from burns and injuries, to respiratory illnesses and mental health issues. These health effects of wildfires are disproportionately impacting vulnerable groups, such as indigenous populations. These indigenous populations however hold unique ancestral knowledge of the land and have cultivated their own best practices for managing it.
Emily Dicken, Ph.D., serves as the Director of Emergency Management with the First Nations Health Authority in British Columbia, Canada. As an Indigenous academic, Dicken works to explore decolonization within the field of emergency management.
Bill Tripp is a Karuk tribal member and Director of Natural Resources and Environmental Policy for the Karuk Tribe Department of Natural Resources in northern California, U.S. Tripp is a specialist on forest management and indigenous fire use. He was co-PD on the USDA-NIFA AFRI Food Security project, and co-author of the Karuk Climate Adaptation Plan. Tripp serves as Co-Chair on the Western Region Strategy Committee for the National Cohesive Wildland Fire Management Strategy, and participates in many other forums focusing on forest and fire management in a manner inclusive of indigenous stewardship.
David Bowman, Ph.D., holds a research chair in Pyrogeography and Fire Science in the School of Natural Sciences and is the Director of the transdisciplinary Fire Centre at the University of Tasmania in Australia. Bowman is developing the transdisciplinary field of pyrogeography that provides a synthetic understanding of landscape burning that unites human, physical, and biological dimensions of fire from the geological past into the future and that spans local to global geographic scales.
Community-based Participatory Research (CBPR) in India
Community-based participatory research (CBPR) is a partnership approach to research that involves community members, organizations, and researchers during all steps of the research process. NIEHS has long recognized the value of CBPR, especially when working with vulnerable populations where community members may not have a voice. Earlier this year, NIEHS coordinated a CBPR workshop that brought together practitioners and stakeholders from two opposite sides of the globe.
Edith Parker, Dr.PH. is the dean of the University of Iowa College of Public Health.

Parker’s research has been funded by the National Institutes of Health and the Centers for Disease Control and Prevention. Her research interests include environmental health interventions and community engagement and outreach.
She is a nationally recognized expert for her work in community-based participatory research (CBPR), which she began focusing on while earning her doctoral degree. Since then, she has consulted on community-academic partnerships around North America, publishing papers on the benefits of CBPR. In 2017, she received the University of Iowa Regents Award for Faculty Excellence, which honors faculty members for work representing a significant contribution to excellence in public education.
Rajesh Tandon, Ph.D. is an internationally acclaimed leader and practitioner of participatory research and development. He founded Participatory Research in Asia (PRIA), an organization that advocates for and provides training in participatory research. Today he serves as the president of the organization, championing the cause of building organizations and capacities in marginalized communities.
As a pioneer of participatory research, Tandon has given new meaning to academic research by redefining the relationship between the researcher and the subjects of that research. He is the co-chair of the UNESCO Chair on Community Based Research and Social Responsibility in Higher Education. He has also served on committees for the Government of India, the University Grants Commission of India, and the United Nations. He has received numerous awards and honors from his work with PRIA and these organizations. In 2011, he was the first Indian to be inducted to the International Adult and Continuing Education Hall of Fame.
Tandon studied electronics engineering at the Indian Institute of Technology, Kanpur. He went on to earn his MBA from the Indian Institute of Management (IIM), Calcutta, and his Ph.D. in management from Case Western Reserve in Cleveland, Ohio. Prior to his work with PRIA, he taught at IIM, Calcutta.
