Résumé (anglais)

Lay Abstract: The goal of this doctoral dissertation was to develop a better understanding of how social, cultural, and ecological systems impact community health and wellbeing in various contexts. Findings indicate climate and shipping changes impact Chesterfield Inlet, Nunavut through the relationship between food security, cultural continuity, and community health and wellbeing. Relatedly, harvesting activities, access to country food, satisfaction in Inuit governance, and community involvement all increase the probability that an Inuk living in the Arctic has good or great self-rated health. Additionally, Locally Managed Marine Areas, an approach to marine resources management that includes community members as key stakeholders, not only aligns with existing local and Indigenous management practices, but can also support biodiversity and increased catch of various species. Finally, by representing these research results in a single model called an ontology, we can make educated guesses about how these different studies are interconnected. The insights gained from this work can be adopted by decisionmakers to create supports for and remove barriers to improved community health and wellbeing and community efforts to adapt to changes. Abstract: An individual’s health is influenced by more than just the health care system, but also in large part by the social determinants of health. People exist within broader social, cultural, and ecological systems which influence their health outcomes through the social determinants of health. This doctoral dissertation examines social, cultural, and ecological systems to understand several factors that support and hinder community health and wellbeing to inform future policy. This dissertation incorporates a mix of methodological approaches across four interrelated research studies to better understand direct and indirect factors influencing community health and wellbeing. In doing so, this thesis is divided into four research chapters. Study 1 consists of a community-based research project that examines how food security, cultural continuity, and community health and wellbeing are connected through the sharing of harvested country food in Chesterfield Inlet, Nunavut, Canada. Based on this understanding we can demonstrate how climate change and increased shipping along the inlet affects the community as a result of changes in marine mammals and harvesting activities. Study 2 presents a logistic regression that models how cultural continuity variables impact self-rated health for participants living in Inuit Nunangat in Canada. This model uses the Arctic Supplement questions of the Aboriginal Peoples Survey to compare measures of cultural continuity to traditional measures based on government services. This study demonstrates an important link between cultural continuity and self-rated health for Inuit living in Inuit Nunangat. iv Study 3 contains a case study of different implementation successes and challenges of Locally Managed Marine Areas globally. These cases are used to understand how community member involvement as stakeholders in marine resource decision-making not only aligns with existing local and Indigenous ways of management, but also can enhance biodiversity as well as local livelihoods. Finally, Study 4 uses ontology engineering methods to represent the results from the first three studies. This study demonstrates how this novel method can be used to illustrate the interconnectedness of results from different disciplines using diverse data sources and through the creation of different scenarios. Taken together, these studies provide timely insights regarding the ways policy can support or hinder efforts to improve community health and wellbeing and adapt to climate changes.
