Dozens of First Nations in Canada lack access to safe and secure water resources. This thesis proposes the decentralization of water treatment in First Nations, and explores how architecture might integrate and decentralize water collection, purification, and storage strategies in Hiawatha First Nation. It simultaneously explores the very deep and layered spiritual connection between women and water in Anishinaabe culture. Feminist theory is used as a lens through which the research and design is approached. Synthesizing vernacular strategies with contemporary technologies led to the development of a regionally sensitive architecture that creates much needed space for purification, healing, and growth of the community and the individual. The Pimaadashkodeyaang Cultural Centre in Hiawatha First Nation investigates Anishinaabe architecture and culture, feminist theory and space, and water and productive landscapes. Multiple design strategies emerged that inform how to design with water from both a pragmatic and mythopoetic perspective.

Retaining of water resources quality is one of the global ecological problems of the modern time. The most promising direction in solving the problem of water resources protection is the reduction of negative environmental influence of waste water from production facilities by upgrading the existing water treatment technologies. To treat utility water, technical and rain water from site facilities of Transneft system entities, the specialists developed and approved standard technological diagrams, which are used in producing treatment facilities. The standard technological diagrams provide for all necessary stages of waste water treatment ensures the reduction of pollution level to normal values. However, during operation of treatment facilities it was established, that to ensure the required quality of waste water treatment with initially high levels of pollution, the new technological solutions are necessary. The author presents the results of scientific-research work, in the context of which the best affordable technologies were identified in the area of the treatment of waste water with increased content of pollutants and non-uniform ingress pattern. On the basis of the research results the technical solutions were developed for optimization of operation of existing waste water treatment facilities by means of using combined treatment of technical and rain waters and utility waste waters and applying bioreactor with movable bed – biochips. The use of bioreactor with movable bed allows the increase in the area of active surface, which facilitates increase and retention of biomass. Biochips are completely immersed into waste waters, and biofilm is formed on the entire volume of immersion area, facilitating retention of biomass and preventing formation of sediments. Due to mixing the floating device with biofilm constantly moves along the whole area of bioreactor, and, in doing so, speeds up biochemical processes and uniformity of treatment. The advantages of a bioreactor with movable bed – its active sludge durability against increased and changing pollutant concentrations, change of waste water temperature and simplicity of application – ensured the possibility of its use for blending utility waters, technical and rain waters.

Individual Risk

Many Indigenous communities across Canada suffer from the lack of access to clean drinking water; ensuring individuals and communities have safe water to drink either from their home or from their local environment requires the consideration of multiple factors including individual risk perception. In collaboration with local leaders, semi-structured interviews (n = 99) were conducted over a two-year period in the Dene Tha’ First Nation and Kátł’odeeche First Nation to unpack the issue of risk perception and its meaning to local community members. These local metrics of risk perception including smell, taste, safety, health fears and level of concern were then used to explore patterns in other data on drinking water consumption patterns and bottled water use. The results are consistent with previous research related to water insecurity and indicate that both communities consume more bottled water than the average Canadian. Results also varied by jurisdiction; those in Alberta indicated much higher levels of concern and a greater degree of bottled water consumption.

AbstractHydrate-based gas separation technology is applicable to the CO2 capture and storage from synthesis gas mixture generated through gasification of fuel sources including biomass. This paper reports visual observations of crystal growth dynamics and crystal morphology of hydrate formed in the H2 + CO2 + tetrahydropyran (THP) + water system with a target for developing the hydrate-based CO2 separation process design. Experiments were conducted at a temperature range of 279.5–284.9 K under the pressure of 4.9–5.3 MPa. To simulate the synthesis gas, gas composition in the gas phase was maintained around H2:CO2 = 0.6:0.4 in mole fraction. Hydrate crystals were formed and extended along the THP/water interface. After the complete coverage of the interface to shape a polycrystalline shell, hydrate crystals continued to grow further into the bulk of liquid water. The individual crystals were identified as hexagonal, tetragonal and other polygonal-shaped formations. The crystal growth rate and the crystal size varied depending on thermodynamic conditions. Implications from the obtained results for the arrangement of operating conditions at the hydrate formation-, transportation-, and dissociation processes are discussed.

Global population growth and water resource scarcity are significant social problems currently being studied by many researchers focusing on finding new materials for water treatment. The aim is to obtain quality water suitable for drinking and industrial consumption. In this sense, an emergent class of crystalline porous materials known as Covalent-Organic Frameworks (COFs) offers a wide range of possibilities since their structures can be designed on demand for specific applications. Indeed, in the last decade, many efforts have been made for their use in water treatment. This perspective article aims to overview the state-of-the-art COFs collecting the most recent results in the field for water detection of pollutants and water treatment. After the introduction, where we overview the classical design strategies on COF design and synthesis for obtaining chemically stable COFs, we summarize the different experimental methodologies used for COFs processing in the form of supported and free-standing membranes and colloids. Finally, we describe the use of COFs in processes involving the detection of pollutants in water and wastewater treatment, such as the capture of organic compounds, heavy metals, and dyes, the degradation of organic pollutants, as well as in desalination processes. Finally, we provide a perspective on the field and the potential technological use of these novel materials.

The transition toward circular economy models has been progressively promoted in the last few years. Different disciplines and strategies may significantly support this change. Although the specific contribution derived from design, material science, and additive manufacturing is well-established, their interdisciplinary relationship in circular economy contexts is relatively unexplored. This paper aims to review the main case studies related to new circular economy models for waste valorization through extrusion-based additive manufacturing, circular materials, and new design strategies. The general patterns were investigated through a comprehensive analysis of 74 case studies from academic research and design practice in the last six-year period (2015–2021), focusing on the application fields, the 3D printing technologies, and the materials. Further considerations and future trends were then included by looking at the relevant funded projects and case studies of 2021. A broader number of applications, circular materials, and technologies were explored by the academic context, concerning the practice-based scenario linked to more consolidated fields. Thanks to the development of new strategies and experiential tools, academic research and practice can be linked to foster new opportunities to implement circular economy models.

Do So

In 2018, the Chippewas of Georgina Island First Nation (GIFN) implemented a First Nation property tax system under the First Nations Fiscal Management Act (FMA)—one of the earliest First Nations in Ontario to do so. Implementation of a property tax system gave GIFN an opportunity to improve funding for and expand local services, and provide a more equitable sharing of local service costs between cottagers leasing First Nation land and the First Nation. Key challenges encountered when implementing the property tax system were building consensus around the need for a tax system, building an appropriate administrative infrastructure, carrying out property assessments, and professionals lacking knowledge of First Nation property tax. These challenges, however, presented opportunities to create a knowledge base around property taxation within GIFN, among cottage leaseholders, and in the wider community. Key lessons learned were (1) start as soon as possible; (2) First Nations Tax Commission support and standards are important; (3) staff training is important; (4) communicate early and often; (5) hold open houses; (6) local services are more than garbage collection; (7) property taxes do not harm lease rates or cottage sales; (8) educate lawyers, real estate agents, and other professionals; (9) startup costs were significant; (10) coordinate laws and standards with provincial variations; (11) modernize systems; and (12) utilize other parts of the FMA.

Introduction Despite high diabetes rates among Canadian First Nations people, little is known about their cardiovascular disease risk. Our aim was to describe the apolipoprotein profile with respect to cardiovascular risk in a Canadian First Nation community. Methods In 2003, a representative sample of adult members of a Manitoba First Nation (N = 483) participated in a screening study for diabetes and diabetes complications. We assessed their cardiovascular risk factors. Results Sixty percent of women were at increased cardiovascular risk because of low apolipoprotein A1 (apoA1) levels, compared with 35% of men. The proportion of women with low apoA1 levels decreased with age, but the proportion with low high-density lipoprotein levels remained stable across age groups. Both apoB and apoA1 were significantly associated with obesity when age, sex, diastolic blood pressure, homocysteine, diabetes, and insulin resistance were controlled for. Conclusion Apolipoprotein and lipid profiles in this First Nation population suggest high cardiovascular risk. Future research should characterize the lipoprotein particle size in this population.

Abstract Background This paper focuses on a longitudinal research program in Manitoba, Canada, by the Innovation Supporting Transformation in Community-Based Research Project (iPHIT) to learn from First Nations across the province that have developed effective community-based primary healthcare models. The research is relevant and timely as First Nations across the country, and Indigenous populations globally, work towards improvements in population health and health equity via critical analysis and restructuring of health services. The purpose of the paper is to deepen an understanding of decolonization as it is defined within the communities, as a central aspect of health restructuring. Methods The study is a qualitative, grounded theory analysis, which is a constructivist approach to social research that allows for generation of theory in praxis, through interactions and conversations between researchers and research participants. Findings are based on 183 in-depth interviews and eight focus group discussions with participants from 8 Manitoba First Nation communities. The study was designed to understand strengths, limitations and priorities of primary healthcare strategies and frameworks of the communities. The iPHIT team was an active collaborative partnership between the First Nation communities, First Nation Health and Social Secretariat of Manitoba, and the University of Manitoba. The First Nation partners led in all aspects of the research, from development to implementation, data collection, analyses, and dissemination. Respected Elders from the communities also guided in appropriate research and engagement protocols. Results Data was coded and then grouped into 4 interconnecting themes. These are: (1) First Nation control of healthcare, (2) traditional medicine and healing activities, (3) full community participation, and (4) moving out of colonization involves cleaning up and moving beyond the mess that colonization has inflicted. Conclusion Decolonizing health involves a taking back of Indigenous wisdom and traditional activities; connections to the land, resources; intra- and inter-community relationships. Participants emphasized the value of full community engagement with respect to inclusion of different interpretations of and experiences in the world, highlighting creation of a shared vision. The study focused on First Nation community experiences and interests in Manitoba specifically, though the data may be applicable to national and global decolonization efforts.
