  • Review of Regional Cumulative Effects Assessment
    Review of Regional Cumulative Effects Assessment October 2017 Prepared for: Manitoba Clean Environment Commission Prepared by: Halket Environmental Consultants Inc. For: O-Pipon-Na-Piwin Cree Nation OPCN Review of the RCEA ii Executive Summary Halket Environmental Consultants was engaged by O-Pipon-Na-Piwin Cree Nation to review the Regional Cumulative Effects Assessment for Hydroelectric Developments on the Churchill, Burntwood and Nelson River Systems, conducted by Manitoba and Manitoba Hydro. After reviewing the assessment we were surprised by the lack of suitable scoping and analyses and also the lack of assessment concerning mitigation measures. Therefore, we, O-Pipon-Na-Piwin Cree Nation (OPCN) wish to comment on the parts of the document that pertain to our traditional territory: Southern Indian Lake (SIL), the Churchill River from Missi Falls to Fidler Lake and the South Bay channel down to Notigi. This territory is represented in the RCEA by Hydraulic Zones 4, 5 and 6, respectively and the South Indian and Baldock terrestrial regions. OPCN were not consulted before the approach to the RCEA was conceived and implemented by Manitoba and Manitoba Hydro. If OPCN had been, the RCEA would be a very different document because it would have addressed the changes that occurred to the environment and community because of the Churchill River Diversion in a much more substantive manner. Best practice for Cumulative Effects Assessment (CEA) recommends that analyses of changes are conducted through comparisons of states of the environment at different points in time, referred to as cases. The RCEA fails to establish a pre-development case, an immediate post- development case, a current case and reasonably foreseeable future development cases.

  • Large-Scale Impacts of Hydroelectric Development
    27 Large-scale impacts of hydroelectric development D.M. Rosenberg,1 F. Berkes, R.A. Bodaly, R.E. Hecky, C.A. Kelly, and J.W.M. Rudd Abstract: The substantial size of some hydroelectric projects and the extensive total surface area covered by reservoirs globally require that research determining the impacts of these developments be done at ever-increasing spatial and temporal scales. As a consequence of this research, new views are emerging about the spatial extent and longevity of the environmental and social impacts of such developments. New findings challenge the notion of hydroelectric development as a benign alternative to other forms of power generation. This review examines the intertwined environmental and social effects of methylmercury bioaccumulation in the food web, emission of greenhouse gases from reservoirs, downstream effects of altered flows, and impacts on biodiversity, each of which operates at its own unique spatial and temporal scales. Methylmercury bioaccumulation occurs at the smallest spatial and temporal scales of the four impacts reviewed, whereas downstream effects usually occur at the largest scales. Greenhouse gas emissions, the newest surprise connected with large-scale hydroelectric development, are relatively short term but eventually may have important global-scale consequences. Limitation of biodiversity by hydroelectric development usually occurs at intermediate spatial and temporal scales. Knowledge developed from working at expanded spatial and temporal scales should be an important part of future decision making for large-scale hydroelectric development. Key words: hydroelectric development, large-scale, environmental impacts, social impacts. Résumé : La dimension considérable de certains projets hydroélectriques et les vastes surfaces totales globalement couvertes par les réservoirs nécessitent que la recherche menée pour déterminer les impacts de ces développements soit conduite à des échelles d’espace et de temps de plus en plus grandes.

    Failed Partnership to Future Partnership: An Examination of Social Impacts Moving from Institutional Failure to Partner with Indigenous Communities to a New Model of Partnership A Thesis submitted to the Faculty of Graduate Studies of The University of Manitoba In partial fulfilment of the requirements of the degree of MASTER OF ARTS Department of History University of Manitoba Winnipeg Copyright © November 2018 Erin Yaremko 0 Acknowledgement of Treaty Territory and Positionality I acknowledge that I reside and work on treaty 1 and treaty 5 territory, the traditional territories of the Anishinaabeg (Ojibway), Muskeko-ininiwak (Cree), Dakota and Nakota peoples, and the homeland of the Red River Métis Nation. As a settler descendant I acknowledge the continuation of modern colonial barriers First Nations continue to face, and am consciously aware of the white privilege I carry. I commit myself to building reciprocal partnerships and alliances to further the growth of the Indigenous perspective in historical source. I come to this research and work with anticolonial, anti-racist world views and commit myself to furthering my own personal growth and understanding of Indigenous methodology and world views through continual alliance with each Nation I am fortunate to partner with. My early upbringing through inner city volunteer positions and further work in areas of social justice facilitated the growth of my passion for social justice-based research and work in partnership with other cultural groups. Past work in partnership with the Japanese Canadian based project Landscapes of Injustice helped foster my understanding of large social justice- based research projects. Work in partnership with the Japanese Manitoban and Japanese Saskatchewan communities furthered my understanding of colonization in Canada and the trauma caused by western society.

When reservoirs are created, bacterial decomposition of flooded organic material causes a small amount of the inorganic mercury sequestered in these soils to be converted into organic or methylmercury (MeHg). Methylmercury is easily absorbed by aquatic organisms that feed in sediments and becomes accumulated and concentrated at progressively higher concentrations moving up the aquatic food web.

    Memorial to Frederick James Alcock 1888-1972 DR. HUGH S. BOSTOCK 2150 West bourne Avenue, Ottawa, Ontario, Canada The death of Frederick James Alcock in his 84th year on the 18th of March 1972 in Ottawa, Ontario, is a great loss to his numerous friends whose interests embrace many walks of life. Fred was born on the 16th of November 1888, in Giiersville, Ontario, and is now buried in Meaford, Ontario, where he spent his boyhood days. In 1927, he married Marion Ethel McBain Freeman and is sur­ vived by her, their two children, Frances Anne and Richard Arthur, and six grandchildren. Fred received his early education in Meaford. From there he entered the University of Toronto, where he majored in geology and mineralogy, and where lie obtained his B.A. degree with first-class honours in 1912. For the next three years, lie studied at Yale University, specializing in structural geology and petrology. Ile received his Ph.D. in 1915. The following year was spent at the University of Wisconsin where he concentrated on Precambrian geology. From 1911 to 1947 he worked with the Geological Survey of Canada and was then appointed Chief Curator of the National Museum of Canada. He retained this position until his retirement in 1956. He began geological field work as a student assistant with the Geological Survey of Canada in 1911. From that season on he spent the summers with the Survey and was appointed to its staff in 1915. His first paper “On Two New C’rinoids from the Trenton Formation of Ontario” was printed in 1912.
