Indigenous Peoples globally are among those who are most acutely experiencing the mental health impacts of climate change; however, little is known about the ways in which Indigenous Peoples globally experience climate-sensitive mental health impacts and outcomes, and how these experiences may vary depending on local socio-cultural contexts, geographical location, and regional variations in climate change. Thus, the goal of this study was to examine the extent, range, and nature of published research investigating the ways in which global Indigenous mental health is impacted by meteorological, seasonal, and climatic changes. Following a systematic scoping review protocol, three electronic databases were searched. To be included, articles had to be empirical research published since 2007 (i.e. since the Intergovernmental Panel on Climate Change’s Fourth Assessment Report); explicitly discuss Indigenous Peoples and describe factors related to climatic variables and mental health. Descriptive data from relevant articles were extracted, and the articles were thematically analyzed. Fifty articles were included for full review. Most primary research articles described research in Canada (38%), Australia (24%), and the United States of America (10%), with the number of articles increasing over time. Mental health outcomes such as strong emotional responses, suicide, depression, and anxiety were linked to changes in meteorological factors, seasonality, and exposure to both acute and chronic weather events. The literature also reported on the ways in which the emotional and psychological impacts of climate were connected to changing place attachment, disrupted cultural continuity, altered food security and systems, forced human mobility, and intangible loss and damages. This review highlights global considerations for Indigenous mental health in relation to climate change, which can support Indigenous-driven initiatives and decision-making to enhance mental wellness in a changing climate.

The term planetary health—denoting the interdependence between human health and place at all scales—emerged from the environmental and preventive health movements of the 1970–80s; in 1980, Friends of the Earth expanded the World Health Organization definition of health, stating: “health is a state of complete physical, mental, social and ecological well-being and not merely the absence of disease—personal health involvesplanetary health”. Planetary health is not a new discipline; it is an extension of a concept understood by our ancestors, and remains the vocation of multiple disciplines. Planetary health, inseparably bonded to human health, is formally defined by the inVIVO Planetary Health network as the interdependent vitality of all natural and anthropogenic ecosystems (social, political and otherwise). Here, we provide the historical background and philosophies that have guided the network, and summarize the major themes that emerged at the 7th inVIVO meeting in Canmore, Alberta, Canada. We also provide the Canmore Declaration, a Statement of Principles for Planetary Health. This consensus statement, framed by representative participants, expands upon the 1986 Ottawa Charter for Health Promotion and affirms the urgent need to consider the health of people, places and the planet as indistinguishable.

Rapid environmental change due to climate change impacts Inuit mental wellness by altering the relationships between people, place, livelihoods, and culture. Little is known, however, about how fluctuations in weather contribute to the experience of place and the connection to mental wellness in Inuit communities. This study aimed to characterize the importance of changes in weather among Inuit, and how these changes influence mental health and wellness in the context of climate change. Data were drawn from a community-driven and Inuit-led study in the Nunatsiavut region of Labrador, Canada. In-depth interviews (n = 116 people) were conducted between November 2012 to May 2013 in the five Nunatsiavut communities. Qualitative data were thematically analyzed using a constant comparative method. Results indicated that weather impacted mental wellness through three key pathways: 1) shaping daily lived experiences including connection to place and other determinants of wellbeing; 2) altering mood and emotion on a transient basis; and 3) seasonally influencing individual and community health and wellbeing. These results demonstrate the immediate role weather has in shaping mental wellness in Nunatsiavut. In turn, this understanding of the climate-mental wellness relationship points to multiple pathways for action on climate adaptation policy and programming, and underscores the need for more culturally-specific and place-based investigations to appropriately respond to the mental health impacts of climate change.

Across Inuit Nunangat, Inuit rely on wildlife for food security, cultural continuity, intergenerational learning, and livelihoods. Caribou has been an essential species for Inuit for millennia, providing food, clothing, significant cultural practices, and knowledge-sharing. Current declines in many caribou populations—often coupled with hunting moratoriums—have significant impacts on Inuit food, culture, livelihoods, and well-being. Following an Inuit-led approach, this study characterized Inuit-caribou relationships; explored Inuit perspectives on how caribou have been managed; and identified opportunities for sustaining the Mealy Mountain Caribou. Qualitative data were collected in Rigolet, Nunatsiavut, Labrador, Canada through 21 in-depth interviews and two community open houses. Data were analyzed using constant comparative methods and thematic analysis. Rigolet Inuit described: how conservation management decisions had disrupted important connections among caribou and Inuit, particularly related to food, culture, and well-being; the socio-cultural and emotional impacts of the criminalization of an important cultural practice, as well as perceived inequities in wildlife conservation enforcement; and the frustration, anger, and hurt with not being heard or included in caribou management decisions. These results provide insights into experiences of historic and ongoing colonial wildlife management decisions, and highlight future directions for management initiatives for the health and well-being of Inuit and caribou.
