The Inuit Food System: Ecological, Economic, and Environmental Dimensions of the Nutrition TransitionKenny, Tiffannie January 2017 (has links)
From the Arctic to the South Pacific, Indigenous Peoples have experienced a rapid nutrition transition involving the decline of traditional/subsistence-based ways of life and the adoption of a “Western” diet that is high in saturated fats, sugar, and processed foods. This dietary shift has been paralleled by an increased prevalence of obesity, diabetes, and, other diet-related chronic diseases.
In the Arctic, rapidly changing biophysical conditions, globalization, and integration into market economies are collectively challenging access to both country foods and nutritious market foods. Food security and nutrient adequacy thus remain elusive for Inuit communities of northern Canada. Premised upon the view that human well-being is predicated upon complex and dynamic interactions between ecosystems, economies, and societies, this dissertation integrates multiple lines of inquiry and scales of engagement (community, regional, and national) to further understanding of the nutrition transition among Inuit in Canada. The thesis is comprised of two sections.
Section 1 bridges the often disparate fields of human nutrition and wildlife conservation by addressing key questions about the status and management of Arctic species, and the implications for Inuit food security and health. For example, caribou (Rangifer tarandus) populations across the circumpolar north are currently experiencing dramatic declines in abundance and restrictions on Inuit subsistence harvest are currently implemented for several caribou populations. Caribou, however, is the primary source of protein and several micronutrients involved in the prevention of anemia (e.g. iron zinc, copper, riboflavin, and vitamin B12) in the contemporary diet of Inuit adults. Caribou consumption is also positively associated with hemoglobin levels in Inuit adults.
Section 2 considers elements of the market food system in Inuit communities. We found that the most popular market foods consumed by Inuit (e.g. sweetened beverages, added sugar, and bread) contribute significantly to total diet energy while contributing minimally to most micronutrients. Using optimization models, we have demonstrated that a nutritious diet (one meeting Health Canada dietary reference intake values) is theoretically feasible based on a mix of country food and market food, and at relatively little additional cost from current diets. However, significant deviations in patterns of food expenditure away from sweetened beverages, towards dairy, and whole fruits and vegetables would be required.
Taken collectively, this thesis provides important information, as well as new tools, and approaches, for communities, wildlife conservation and public health professionals to jointly promote ecosystem and human health in a rapidly changing environment.

Exploring the phenomena “foraging” in urban green spaces : examples from Järva City District and Stockholm County / Utforskande av fenomenet att samla och plocka i urbana grönområden : exempel från Järva och StockholmMoum Rieser, Anja January 2020 (has links)
As cities globally experience rapid urbanization, the pressure on urban green areas increases and simultaneously opportunities for human-nature interactions decrease, which are crucial for urban citizens’ wellbeing. Urban foraging- the gathering of plant or fungal materials in urban areas- is a common human-nature interaction that has been inadequately studied and overlooked in urban policy, planning, and design. The objective of this thesis is to gain insights into the practices, motivations, and barriers of foragers in Järva City District and Stockholm County. Through an exploratory mixed methodology approach, this study demonstrated that urban foraging is perceived as a recreational activity that motivates people to get out in nature and connects them to biodiversity in forests and parks within the city. Foraging links people to high quality and local food and encourages the sharing of local ecological knowledge. Foragers investigated display care for nature, indicating that foraging can nurture a bond between nature and urban citizens. The expressed barriers to foraging were time, proximity, lack of knowledge, and fear of pollution. The findings show that foraging provides various benefits for citizens in Stockholm County and Järva City District, implying that urban foraging should not be overlooked in future research and assessments, and should be considered and incorporated into urban policy, planning, and design. / Green Access

Anatomy and nutritional value of Dracaena camerooniana BakerLautenschläger, Thea, Frommherz, Lara, Monzi, Mawunu, Neinhuis, Christoph, Henle, Thomas, Förster, Anke 08 May 2023 (has links)
Even though some Dracaena species are used as medicine, their utilization as food is rather unusual. In northern Angola, however, leaves and underground tubers of Dracaena camerooniana Baker are frequently consumed. In particular, the leaves are of increasing economic value in the region. But the anatomy and nutritional aspects of the plant have not been studied so far. Therefore, a detailed anatomic description of the plant was conducted. In a second step the nutritional value of the defined material was analysed, providing a basis for the discussion of a more intensive utilisation of this rainforest shrub.
