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.

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.

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.
