This thesis explores the lives of Maasai women today in general, and in particular as seen through the lens of one woman, and her social network in Kajiado County, southern Kenya. By using a storytelling approach, I let the women’s own vivid stories, thoughts and priorities stay in focus. While the women’s stories reveal personal details in their lives, I argue that their stories also broaden the perspective of what it is to be a Maasai woman today. Inspired by a framework of multispecies relations, especially the concept of relatedness, I look at the relationships – to both humans and non-humans – which shapes the women's lives, possibilities, decisions, and concerns. As I explore the women's more-than-human worlds, the agency of cows, goats, sheep, and even flies are acknowledged. In combination with inspiration from the framework of feminist political ecology – especially the concepts of resource access and displacement – I bridge understandings about how multispecies relations affect the women, with reflections on education and working situations, and matters of land. With this thesis, I wish to contribute to and broaden the literature and often stereotyped image of what it is to be a Maasai, especially a Maasai woman.

My dissertation research investigates the impacts of biodiversity conservation on the local population living in the Sundarban Biosphere Reserve (SBR). More specifically, the research examines the impacts of conservation on local fishing communities living on the edge of the Sundarban Reserve Forest. In addition, it examines the causes and characteristics of conflicts between the biosphere reserve managers and the local fishing communities over the resource use of the biosphere reserve. The research project also explores the impacts of ecotourism on the local population that lives on the edge of the Sundarban Tiger Reserve (STR). STR is one of the important components of the larger biosphere reserve and the core area of the STR overlaps with the core area of the SBR. Findings from research indicate that the current management of the SBR in many ways replicates a fortress conservation model in which local fishermen are denied access to the fishing grounds in the core and sanctuary areas of the STR. Furthermore, the regulation of number of boats through the Boat Licensing Certificate (BLC) creates an avenue for illegal fishing in the STR. Illegal fishing makes fishermen more vulnerable to tiger attacks as the fishermen try to avoid the patrolling forest guards and hide themselves deep in the forest. Fishermen also pay frequent fine for illegal fishing and face harassments from the biosphere resource managers. The confiscation of BLCs and fishing implements also leads to significant loss of fishing time. Additionally, the research shows how the characteristics of a fortress conservation model continue to live on despite there was no instances of eviction during the formation of the SundarbanTiger Reserve in 1973. In sum, this dissertation transforms our overall understanding of a fortress conservation model and suggests that we need to consider broader environmental and political history of a region to understand conservation in a given territory.

Pregnancy is affected by multiple factors both within and outside of a woman’s control. For those who experience a preterm pregnancy, considerations about their experiences can be revelatory and meaningful in understanding concepts such as information sharing, support systems, and care models. This research uses qualitative description to further enhance our knowledge about women’s preterm birth experiences within the Hamilton Niagara Haldimand Brant (HNHB) Local Health Integration Network (LHIN). Participant interviews (n=13), key informant interviews (n=2), and participant observations were conducted. Findings exposed 6 themes: 1) prenatal preparedness; 2) working while pregnant; 3) delivery expectations; 4) place and space; 5) supports and resource attainment; and 6) attitudes and knowledge. Collectively, the themes point to the need for improvements in service delivery and knowledge acquisition, and also suggest a new paradigm of employment involvement in pregnancy as well as reaffirmed or rebranded client-provider expectations during pregnancy. / Thesis / Master of Arts (MA)

This dissertation reviews the progress in climate, land, energy and water (CLEW) multi-scale models and proposes a framework for quantitative assessment of multi-sector long-term policies. The so-called CLEW nexus approaches have shown their usefulness in assessing strategies to achieve the Sustainable Development Goals in the contexts of increasing demands, resource scarcity, and climate change. This thesis contributes to existing research by (1) focusing on the palette of feasible long-term sustainable solutions at different scales to face current and future sustainable development challenges; (2) improving understanding of how CLEW models can best advise on sustainable development research and highlighting the strengths and limitations of existing configurations; (3) inquiring what is needed for new tools to be accessible, transferable and successful in informing the final user. This dissertation first reviews a set of models that can meet the needs of decision makers discussing research gaps and critical needs and opportunities for further model development from a scientific viewpoint. Particular attention is given to model accessibility, usability, and community support. The review explores at different scales where and why some nexus interactions are most relevant, finding, for example, that both very small scale and global models tend to neglect some CLEW interactions. This dissertation also presents the Nexus Solutions Tool (NEST): a new open modeling platform that integrates multi-scale energy-water-land resource optimization with distributed hydrological modeling. The new approach provides insights into the vulnerability of water, energy and land resources to future socioeconomic and climatic change and how multi-sectoral policies, technological solutions and investments can improve the resilience and sustainability of transformation pathways while avoiding counterproductive interactions among sectors. Finally, a case study analysis of the Indus River Basin in South Asia demonstrates the capability of the NEST framework to capture important interlinkages across system transformation pathways towards the United Nations' Sustainable Development Goals. The results show how the Indus countries could lower costs for development and reduce soil pollution and water stress, by cooperating on water resources, electricity and food production. / Graduate

Asians and expatriate Africans have been prominent in the SMME economy of South Africa. This work seeks to establish reasons for the growth and competitiveness of SMMEs run by these groups compared to those operated by local citizens. Reasons for this competitiveness are gleaned from existing literature and presented in accordance with the Perren model which attributes the growth of SMMEs to the owner’s motivation, expertise in managing growth, access to resources, and demand. In this work, the Perren model was first applied to Asians and Lebanese in East and West Africa to set a foundation for comparison with the South African situation. This work concluded that it is the four interim growth drivers acting together that cause competitiveness of Asian- or expatriate African-owned SMMEs. Policy recommendations to improve competitiveness of SMMEs owned by local citizens are then suggested at the end. / Economics / M. Com. (Economics)

Actualmente nos encontramos en un momento de profunda transformación en la historia de la humanidad y de las leyes de la naturaleza caracterizada, entre otras cosas, por un desarrollo expansivo de la industria biotecnológica. La biotecnología tiene como materia prima los recursos genéticos y, también, los extractos bioquímicos de las especies vegetales, animales y microbianas que componen la diversidad biológica, la cual permite un sin fin de posibilidades alimenticias, medicinales, energéticas, industriales entre otros recursos básicos que proveen bienes y servicios esenciales a la pervivencia de la especie humana al mismo tiempo que constituye un elemento integrante de la red de la vida.Si, la perpetua tradición del biocolonialismo o biopiratería que desarrollaron algunos pocos países arrollando a muchos se atenúa o, siendo optimistas, se extingue observando las normas que edifican el Convenio sobre la diversidad biológica y, especialmente, el régimen de acceso a los recursos genéticos en él instituido (artículo 15), las posibilidades de crecimiento económico y, consecuentemente, de desarrollo humano de estos países podría ser una de las innumerables alternativas para empezar a tomar forma. Además, la minimización de los efectos perniciosos sobre la diversidad biológica, mediante su conservación y la aplicación del paradigma desarrollo sostenible, podría favorecer y corregir el dilema utilización versus deterioro.Así pues, el artículo 15 del referido Convenio ofrece por primera vez en el Derecho internacional público un régimen jurídico para un acceso a recursos genéticos legalmente constituido. La característica principal del mismo es que el acceso a un determinado recurso genético se trata de una expectativa sometida a complejas y a la vez oportunas condiciones. Por una parte, está vinculado a contraprestaciones anteriormente inexistentes, las cuales afectan especialmente a la parte usuaria: la transferencia de tecnologías, incluidas las biotecnologías; la distribución justa y equitativa de los beneficios provenientes de cualquier modalidad de utilización y la realización de investigaciones científicas basadas en los recursos accedidos. Por otra parte, está vinculado a la legislación nacional del Estado suministrador del recurso, al consentimiento fundamentado previo del mismo e a las condiciones mutuamente convenidas en la negociación de los acuerdos que le darán vida jurídica.

Les activités anthropiques affectent les cycles biogéochimiques globaux, principalement par l'ajout de nutriments dans les écosystèmes. Il est donc crucial de déterminer dans quelle mesure les cycles biogéochimiques globaux peuvent être régulés. Les autotrophes peuvent réguler les réservoirs de nutriments par la consommation des ressources, mais la majorité des ressources leur sont inaccessibles à l'échelle globale. Par des modèles théoriques, nous avons cherché à évaluer la manière dont les autotrophes répondent à la fertilisation à l'échelle globale et leur capacité à réguler les concentrations des nutriments quand leur accessibilité est limitée. Nous avons également étudié les mécanismes qui déterminent la régulation des rapports de Redfield dans l'océan, ainsi que les effets de l'ajout de nutriments sur la production primaire océanique totale. Nous avons montré que les organismes ne régulent pas efficacement les réservoirs de nutriments. Le couplage des cycles biogéochimiques et la compétition entre groupes fonctionnels peuvent altérer, négativement ou positivement, la régulation des cycles biogéochimiques globaux par les organismes. Une régulation inefficace des concentrations de nutriments n'exclut par contre pas une forte régulation des rapports entre ces nutriments, comme dans le cas des rapports de Redfield. La fertilisation des écosystèmes terrestres et océaniques risque donc de fortement impacter la production primaire et les cycles biogéochimiques globaux, à de courtes comme à de grandes échelles de temps. / Anthropogenic activities heavily impact global biogeochemical cycles, mainly through nutrient fertilisation of ecosystems; thus it is crucial to assess the extent to which global biogeochemical cycles are regulated. Autotrophs can regulate nutrient pools locally through resource consumption, but most resources are inaccessible to them at global scales. We used theoretical models to assess how organisms respond nutrient fertilisation at global scales and how they can regulate the concentration of these nutrients when their accessibility of is limited. We further investigated the mechanisms driving the regulation of Redfield ratios in oceans, and the effects of nutrient fertilisation on total oceanic primary production. We showed that organisms cannot efficiently regulate nutrient pools. Mechanisms such as coupling of nutrient cycles and competition between functional groups can alter the strength of biotic regulation of global biogeochemical cycles, either positively or negatively. An inefficient regulation of inaccessible nutrient concentration, however, does not exclude a strong biotic regulation of nutrient ratios, as is the case with Redfield ratios in oceans. Nutrient fertilization of oceanic and terrestrial ecosystems is thus likely to have a strong impact on primary production and global nutrient cycles at both small and long timescales.
