To survive in the Arctic, the Inuit have developed a unique relationship with the marine environment and its living organisms. Unlike large marine mammals, the importance of smaller marine organisms for food, health, and wellbeing is largely undocumented. To call attention to these components of the food system in Nunavik, in northern Québec, and to understand their importance for health and wellbeing, Elders in two Inuit communities, Ivujivik and Kangiqsujuaq, were interviewed in May 2014. The objectives of this study were to: 1) document all marine organisms harvested and consumed in these communities; and 2) highlight the importance of these country foods through their position within the Inuit zoological classification, as well as their perceived contribution to health and wellbeing. Fifty-seven species of marine organisms were identified as part of the past or current food system, including birds, mammals, fish, mollusks, crustaceans, echinoderms, and algae. Harvesting location is an import...

Globalization is transforming food systems around the world. With few geographical areas spared from nutritional, dietary and epidemiological transitions, chronic diseases have reached pandemic proportions. A question therefore arises as to the sustainability of local food systems. The overall purpose of this article is to put in perspective how local food systems respond to globalization through the assessment of five different case studies stemming from an international research network of Human-Environment Observatories (OHM), namely Nunavik (Québec, Canada), Oyapock (French Guiana, France), Estarreja (Portugal), Téssékéré (Senegal) and Littoral-Caraïbes (Guadeloupe, France). Each region retains aspects of its traditional food system, albeit under different patterns of influence modelled by various factors. These include history, cultural practices, remoteness and accessibility to and integration of globalized ultra-processed foods that induce differential health impacts. Furthermore, increases in the threat of environmental contamination can undermine the benefits of locally sourced foods for the profit of ultra-processed foods. These case studies demonstrate that: (i) the influence of globalization on food systems can be properly understood by integrating sociohistorical trajectories, socioeconomic and sociocultural context, ongoing local environmental issues and health determinants; and (ii) long-term and transverse monitoring is essential to understand the sustainability of local food systems vis-à-vis globalization.

Introduction: In the French overseas department of French Guiana, in South America, nutrition therapy for the management of diabetes is based on French guidelines. However, this region is demographically diverse and includes several populations of Indigenous Peoples, Parikwene among others, also called Palikur. Due to socio-economical, cultural, and geographical differences, along with distinctions in the local food system, dietary recommendations, which many consider in the context of post-colonial power dynamics, are not well suited to local populations. In the absence of suitable recommendations, it is hypothesized that local populations will adapt their dietary practices considering diabetes as an emerging health problem.Methods: Seventy-five interviews were conducted with community members and Elders, as well as healthcare professionals and administrators providing services to the Parikwene population of Macouria and Saint-Georges de l’Oyapock communes. Data regarding the representation of cassava (Manihot esculenta Crantz) consumption and diabetes were collected via semi-structured interviews and participant observation (i.e., observation and participation in community activities), namely via participating in activities related to the transformation of cassava tubers at swidden and fallow fields.Results and Discussion: Parikwene have adapted the transformation of cassava tubers for their consumption in the management of diabetes.The importance of cassava tubers as a staple and core food to the Parikwene food system was established by identifying it as a cultural keystone species. Narratives illustrated conflicting perceptions regarding the implication of cassava consumption in the development of diabetes. Adaptations to the operational sequence involved in the transformation of cassava tubers led to the production of distinct cassava roasted semolina (i.e., couac), based on organoleptic properties (i.e., sweet, and acidic couac). Preferences for the consumption of acidic couac were grounded in the Parikwene knowledge system, as well as attention to diabetes related symptoms and glucometer readings.Conclusion: These results provide important insights related to knowledge, attitudes, and practices in developing locally and culturally adapted approaches to providing dietary recommendations in the treatment of diabetes.

Background: The prevalence of type 2 diabetes (T2D) in the French overseas department of French Guiana, South America, nearly doubles that in its European counterpart, Metropolitan France. This region is demographically diverse and includes several populations of Indigenous Peoples. Although such populations are at particular risk of developing T2D across the Americas, very little is known about their health status in French Guiana, and accurate numbers of diabetic patients do not exist. Methods: In light of a potential public health crisis, an ethnomedicinal study of diabetes experienced by Indigenous Parikweneh was conducted to provide better insight into the knowledge, attitudes and practices (KAP) related to this quickly emerging disease in French Guiana. Altogether, 75 interviews were conducted with community members and Elders, as well as healthcare professionals and administrators providing services to the Parikweneh population of Macouria and Saint-Georges de l’Oyapock. Results: Interviews suggest a high incidence of T2D in this population, with cases that have risen quickly since the mid-twentieth century. Parikweneh participants linked the development of the illness to dietary changes, notably through the introduction of new and sweet foods. Recognizing the complexity of diabetes and its symptoms, diabetic patients highlighted the importance of biomedical treatments and follow-ups, though they frequently alternated or used them concomitantly with Parikweneh medicines. With the help of biomedical tools (i.e. glucometer), local medicinal practices mirrored biomedical approaches through dietary adaptation and the use of medicinal animals and plants for glycaemic control and the treatment of complications from the disease. Conclusion: Parikweneh are appropriating T2D into their knowledge system and adapting their health system in response to this relatively new health concern. A greater understanding of local practices and perceptions relating to T2D among medical staff may therefore be beneficial for meeting patients’ needs, providing greater autonomy in their health path, and improving treatment outcomes.

Local medicinal systems, sometimes referred to as “traditional”, are characterized by a strong integration between human, animal and ecosystem health, of which the rich interdependencies are central tenets of the One Health perspective. Drawing inspiration from the concept of cultural keystone species, developed over the last twenty years to deepen understanding of the importance of certain non-human species in local societies and the reciprocal relationships between them, we propose the concept of medicinal keystone species. They can be defined according to six criteria: (i) intensity, type, and diversity of medicinal use; (ii) naming and terminology within languages; (iii) role in narratives, ceremonies, or symbolism; (iv) persistence and memory of use despite changes in and threats to the medicine system; (v) Visibility and intelligibility of the foundations of a medicinal system; (vi) opportunities for resource acquisition from beyond local territories. Two examples are presented to illustrate the medicinal keystone species framework: (1) Quassia amara , a plant prominent in French Guianese Creole medicine, and (2) Castor canadensis , an animal central to medicinal systems of Algonquian Peoples of Eastern Canada. This concept may play an important role in the conservation of social-ecological systems. By identifying sets of resources that fulfil structural and functional roles in both local medicinal systems and the cultural identity of peoples and society, it helps recognize the medicinal knowledge systems of Indigenous Peoples and Local Communities (IPLC), including Afro-descendants, and emphasizes key components of their materia medica . In this way, it can support more effective access to local medicines in healthcare systems.
