Elements of Successful Food Sovereignty Interventions within Indigenous Communities in the United States and Canada: a Systematic Review

Despite inherent resiliency and strengths, Indigenous Peoples in the United States and Canada have been impacted by colonialism, which has led to a loss of land, culture, and identity. Loss of land in particular has had substantial impacts on Indigenous food system practices. Indigenous food sovereignty (IFS) has been determined to be a mechanism for Indigenous communities to build their capacity to address food insecurity. A systematic review methodology was therefore engaged to gather and analyze the currently published literature to date to identify common elements of successful IFS interventions within Indigenous communities in the United States and Canada. We carried out a systematic search of the following electronic databases: Academic Search Premier, Agricola, PubMed, CINAHL Complete, Indigenous Studies Portal, the Native Health Database, SocIndex, PsycInfo, and Google Scholar. The Mixed Methods Appraisal Tool was used to apply a methodologic quality score to the included articles. We used a 2-stage process for article selection with 2 independent reviewers screening the titles and abstracts of articles identified. Relevant databases were initially searched up to June 2022 with an updated search occurring in January 2023. Content analysis was carried out on the included articles using qualitative analysis software. Twenty articles met the inclusion criteria of the review. Four main categories of successful elements within IFS interventions were identified, including 1) transmission of knowledge and skills within the community through workshops, 2) cultural connectedness through cultivation practices, 3) preparation and consumption of traditional foods through community programs, and 4) community-based partnerships and collaborations. An IFS approach has led to the development of several intervention strategies within Indigenous communities, which have been highlighted in this review. The successful elements identified in this review may serve to support future food sovereignty-related programmatic and intervention development within Indigenous communities.
