Geopsychiatry: Climate change, migration, and mental health.

Geopsychiatry, a newly emerging discipline within psychiatry, examines the influence of geopolitical determinants on mental health and mental illness. Geopolitical determinants include conflict and wars, global austerity, climate change, public health crises (such as the coronavirus disease 2019 (COVID-19)), and migration. This study focuses on the two significant areas of climate change and migration. Climate change can affect mental health directly or indirectly in a variety of ways, including chronic (global warming) and acute (heat waves and environmental disasters) events. Certain groups of migrants, including migrating children, older migrants, refugees, and asylum seekers, are particularly vulnerable to developing psychiatric disorders. The convergence of climate change and migration is significantly complicating the already highly difficult situation for mental health services worldwide, particularly in low- and middle-income countries where access to care is limited. Despite this, the majority of studies examining mental health impacts of these events originate from high-income countries, and there is still a lack of effective preventive and treatment strategies. In 2023, the World Psychiatric Association (WPA) set up a Special Interest Group on Geopsychiatry with a clear and explicit aim to summarize current evidence and propose strategies to tackle geopolitical challenges on mental health. The Special Interest Group aims to support regional and local groups across all psychiatric disciplines and stakeholders dedicated to building local consensus, prioritizing research, crafting policies, and collating and sharing good clinical practices. With such significant effort, we can expand our understanding and collaboration on geopsychiatry and make changes to the care of people with geopolitical and mental health challenges around the globe.
