Lake Victoria (LV), is the largest tropical fresh water lake. It is however facing a myriad of challenges like eutrophication, introducing species, mass extinction and climate change. Eutrophication has mostly been seen as a result of non-point pollution from upstream agricultural areas. However, studies have found that atmospheric deposition could perhaps be the greatest cause of nutrient loading in the lake. Our study looked at black carbon as one of the factors favoring eutrophication in LV. Black carbon is a product of incomplete combustion of biomass or fossil fuel. Biomass burning is prevalent in many areas of Africa and our results have shown a great spatial and temporal variability in its concentration in sediments. The sedimentation rates calculated after analyzing 210Pb activity were 0.87, 0.53 and 0.35 g cm-2 yr-1 while the average black carbon concentrations were 4.6, 2.1 and 6.9 mg g-1 for Siaya, Kisumu and Busia, respectively. These results provided valuable information when compared to past historical events in the Lake region especially eutrophication. The study also found that soot BC has been increasing in the past 100 years suggesting the input from fossil fuels. This study elucidates the complexity of drivers of eutrophication in Lake Victoria. Nitrogen and Phosphorous from the upstream agricultural sites has long been seen as the main cause of eutrophication. Through this study we find that soot deposition in the lake coincides with the period of increased primary productivity. The Total Organic Carbon and Total Nitrogen were also analyzed and have shown increased remarkable increase with time. All these geochemical variables are a testament to the increased role of human activities on the lake’s productivity. While other studies on soot in marine environments have associated bacterial growth to nutrients attached to soot black carbon. We correlate the concentration of soot in Lake Victoria basin to blooming of cyanobacteria.

This dissertation is a combined digital history-narrative history project. It takes advantage of newly digitized historical newspapers and soldier files to explore how the people of Victoria B.C. Canada, over 8000 kilometers from the front, experienced the Great War 1914-1918. Although that experience was similar to other Canadian cities in many ways, in other respects it was quite different. Victoria’s geographical location on the very fringe of the Empire sets it apart. Demographic and ethnic differences from the rest of Canada and a very different history of indigenous-settler relations had a dramatic effect on who went to war, who resisted and how war was commemorated in Victoria. This study of Victoria will also provide an opportunity to examine several important thematic areas that may impact the broader understanding of Canada in the Great War not covered in earlier works. These themes include the recruiting of under-age soldiers, the response to the naval threat in the Pacific, resistance by indigenous peoples, and the highly effective response to the threat of influenza at the end of the war. As the project manager for the City Goes to War web-site, I directed the development of an extensive on-line archive of supporting documents and articles about Victoria during the Great War that supports this work (http://acitygoestowar.ca/). Once reviewed by the committee, this paper will be converted to web format and added to that project. / Graduate

There remain vast knowledge gaps in the global south as to how tourism will affect climate change and vice versa. Recent extreme weather events in southern Africa attributed to climate variability and change have led to speculation that, the Victoria Falls, is under threat from climate change. This research was aimed at examining the two-way linkage between tourism and climate change. The research adopted a pragmatism paradigm in a mixed-method case study. A number of research techniques were used to investigate the problem, namely: an online survey (n=427), secondary data analysis, field observation and interviews. Data analysis was done making use of Mann-Kendall Trend Analysis, QuestionPro analytics, Microsoft Excel Analysis Toolpak, Tools from ArcMap 10.3.1 and SPSS 24. Content analysis and thematic analysis was used to analyse secondary and interview data respectively. It emerged that the Victoria Falls is experiencing climate change, which resulted in statistically significant increase in temperature over the past 40 years of between 0.3°C and 0.75°C per decade. However, no significant changes in rainfall were noted, although there has been a seasonal shift in average rainfall onset. Weather extremes and annual rainfall point to increased occurrence and severity of extreme years of droughts and wetting which has in turn also affected waterflow regime at the waterfalls. The changes have a negative impact on wildlife, tourists, and tourism business in the area. The study also revealed that tourism is an equally significant driver of climate change through carbon emissions throughout its value chain. Carbon emissions from tourism value chain are set to increase in the foreseeable future despite efforts of going green by the industry owing to exponential growth of the industry. There is, therefore, a need for the industry to adapt, mitigate and intensify green tourism efforts to achieve sustainability. The study further suggests that there is a need for better communication and education to build resilience and capacity for the tourism industry to deal with climate change. Further research is suggested to ascertain the tourism threshold for the area, impact of climate change on wildlife and basin changes that led to water flow increase in the Zambezi River. / Environmental Sciences / Ph.

La presente investigación aborda la crisis actual –evidenciada desde el 2015- que atraviesa el conglomerado textil Gamarra en el contexto de una ciudad neoliberal como Lima: desregulada, privatizada y que favorece capitales extranjeros. Se buscó analizar las estrategias desplegadas por una selección de empresarios que actualmente cuentan con una posición de estabilidad y liderazgo en el conglomerado. Se planteó que las trayectorias de los empresarios, así como sus experiencias concretas en un entorno comercial con características locales específicas, devienen en lecturas particulares de la crisis, así como en diversas estrategias para sobrevivir a ella. Al contar con distintas trayectorias, y por tanto distintas habilidades y conocimientos, los empresarios cuentan con capacidades diferenciadas para influir en las transformaciones del conglomerado. El estudio tiene carácter exploratorio. Para ello, se eligió aproximarnos a las historias de vida de una muestra de empresarios a través de entrevistas a profundidad. Los ejes sobre los cuales giraron las entrevistas fueron sus experiencias tanto laborales como de vida dentro del conglomerado. Los resultados fueron presentados a partir de dos estrategias principales. La primera, Reivindicación, consistió en estrategias de carácter colectivo que buscan mantener el valor espacial de Gamarra que surgió al conformarse y que considera necesario mantener una amplia red de empresarios así como su carácter de aglomeración económica. La segunda, Privatización, consistió en estrategias que generan espacios privados como las galerías-malls, y que busca generar productos especializados similares a los de las marcas transnacionales así como estrategias des-localizadas de venta a través de redes sociales y envíos motorizados. Finalmente, lo que ambas estrategias tuvieron en común fue haber sido construidas al margen del Estado. Ambas buscan mantener su potencial comercial así como una identidad autónoma en el conglomerado. / Tesis

In Australia and the US, women play a vital role in the agricultural sector. However, historically farmwomen’s contributions to agriculture as well as their individual knowledge and social resilience to stressors like climate and climate change have been unrecognized and rendered invisible. Drawing on interdisciplinary scholarship from geography and the humanities, this dissertation explores the farm as place in a changing climate, drawing on women farmers’ experiences, under three distinct themes: identity, place, and photography. The dissertation research includes three distinct parts. First, incorporating non-fiction writing and photography, I explore my agricultural and religious heritage, as well as familial connections to the landscape of rural Idaho. Second, and in conjunction with The Invisible Farmer Project, the largest ever study of Australian women on the land, I analyze women’s photo voices, relying primarily on interview and Facebook data, as well as photographs, to understand women’s emotive connections to the farm as place, farmer identities, and roles in the agricultural sector. Analysis of the Facebook posts revealed how women are establishing a new dialog about what it means to be a woman farmer and how emotion is the foundation for establishing community and connection. Women's posted photo voices allow us to gain new insights into the women farmers' connections to the farm as place as well as their diversified perspectives and identities. Third, using integrative methods, I study women farmers and ranchers in Idaho, United States and Victoria, Australia through an environmental history lens. Examining the history of water in each region, and how the layering of social and environmental factors shapes the farm as place, resilience, and women’s work, I study how the identities of the women farmers and the farm as place cannot be separated. In both the second and third parts, I seek to redefine "farmer" by revealing experiences that have been invisible in the traditional agricultural sector. Rural women farmers have diverse identities and experiences, and their contributions to the agricultural sector are significant. They perceive and adapt to climate impacts and they are resilient. Their experiences with the farm as place is at the center of their identities, resilience, day-to-day work, and shapes their adaptation strategies and emotional well-being.

This research examines the impact, if any, of the introduction of casemix funding on public hospitals in Victoria. The results reported here show that in Victoria, during the period under observation, rural hospitals showed a significantly greater preponderance, relative to metropolitan hospitals, to either amalgamate or close down. Since 1 July 1993 public hospitals in Victoria have been compared for efficiency in the delivery of their services. The casemix funding arrangements were installed, among other reasons, to improve efficiency in the delivery of hospital services. Duckett, 1999, p 107 states that under casemix funding 'The hospital therefore becomes more clearly accountable for variation in the efficiency of the services it provides'. Also, 'Generally, case-mix funding is seen as being able to yield efficiency improvements more rapidly than negotiated funding'. Hospital comparisons provide State bodies with information on how to allocate funding between hospitals by means of annual capped budgets. Budgets are capped because funding is restricted to a given number of patients that can be treated in any given year. Thus, casemix funding relies heavily on cost comparisons between hospitals, and the way that hospital output is measured relies on the use of diagnosis related groups (DRGs).
