The draining of the Iraqi Marshlands is an example of the reorganization of a linked social-ecological system (SES) following a collapse. The goal of this study was to examine the utility of resilience as a water management tool through a case study of the Marshlands. Using the Four-Step Framework by Walker et al. (2002), it analyzed the Marshlands through the metaphor of the adaptive cycle, explored three possible future scenarios, created two models to characterize the system, and reviewed the implications of the analysis for water management in the Marshlands and resilience. This study found that resilience, and the Framework, could offer new perspectives for managing complex SESs. However, resilience is not useful during times of intense violent conflict, like war. It also found that there are resilient pathways to help the Marshlands reorganize. However, the Marshlands are very vulnerable and require strong institutional support to keep them from disappearing.

Several ways of understanding aboriginal rights surfaced in the wake of section 35 of the Constitution Act, 1982, which recognizes and affirms aboriginal and treaty rights. During my Masters’ studies, I journeyed these ways, propelled by a troubling dream that came to me while I was in law school. The dream prompted me to reconsider rights and to choose my words with caution and with care. And yet when I thought of what my dream might be trying to tell me, I was afraid. I was afraid to question rights, especially aboriginal rights. There seemed to be so much of me tied up in the cause and construction of aboriginal rights. All through law school I wanted there to be an answer I could find and defend. I wanted there to be a right way to think about aboriginal rights, something that would guarantee me a protected space to be. I wanted to continue pursuing that protection. And yet, there was my dream. Among the Anishinabe, dreams are considered gifts, for they lead us toward our greatest laws and teachings. Though I was loath to question aboriginal rights, I was not willing to question my dream. So I readied myself, preparing to put aboriginal rights into question. To my thesis, I brought all the learning I had done in and outside of law school. I also brought a question to guide me. To give me courage, I carried my faith in who I am, as Anishinabe. Knowing for all that I am Dawnis Kennedy, I am also Minawaanigogiizhigok, I set out to see what I would see. The question that led me through understandings of section 35 is this: do recent understandings of aboriginal rights within Canadian law enable Canadian courts to transform adverse relations with indigenous legal orders? The answer I found is, not yet. The interpretations of aboriginal rights I encountered have effected considerable change within Canadian law. However, my journey shows more is needed before the aboriginal rights framework can support respectful engagements with indigenous law. Indeed, without fundamental reorientation, I believe aboriginal rights jurisprudence will further entrench, rather than transform, Canadian law’s adverse relations with indigenous peoples. I would ask judges, lawyers, legislators, and all who shape Canadian law, to break away from attempts to reconcile indigenous and Canadian law within Canadian legal orders and reorient themselves towards fostering respect between indigenous and Canadian legal orders. In writing my thesis, I found cause for my concern with rights. And yet, this is not all that I found. Also, I found myself able to engage the world beyond the protective limits aboriginal rights provide. I found the ability to trust in another form of law, Anishinabe inaakonigewin, to understand my relations and actions in the world. This trust helped me to find the will to move beyond critiquing systems, toward engaging people.

This thesis analyzes the relationship between the legal traditions of indigenous peoples and the Canadian State. I posit that the current relationship is aptly characterized as imperial. The imperial dynamics of this relationship perpetuate imbalances of power between the two traditions. This situation of power imbalance produces two effects that are of concern here. First, it enframes the development of indigenous legal traditions within the liberal state, domesticating indigenous norms to accord with liberal norms. Second, it disencumbers indigenous peoples ancestral territories from indigenous authority that would inhibit Canadian and global market penetration. I rely on theoretical literature in the fields of legal pluralism and postcolonialism to develop this argument. A deep conception of legal pluralism allows us, as researchers, to think of state law as developed by a single legal tradition that co-exists with indigenous legal traditions. Postcolonial theory aids us in analyzing the particular manner in which power works in situations of colonialism and imperialism to privilege certain legal orders over others. I suggest that indigenous life is not fully enclosed by imperialism, and that as indigenous peoples we should engage those non-imperial sites and practices deeply to thicken our capacity to live freely. I suggest indigenous practices of totemism represent one such site.

The retail landscape has changed significantly since the mid 20th century, evolving from a city centre focus through strip malls, shopping centres, shopping malls, mega-malls, big box stores, and to the newest form of retailing - the lifestyle commercial centres. One constant through this evolution has been the permissive role of land use regulations in shaping the form and location of retailing. At issue is whether local governments, and in particular land use planners, have abandoned a holistic approach to evaluating the public good and instead focused solely on the economic benefits gained from new development. This study offers a new approach to understanding the "boxed in" relationship between the retail landscape and the public good: that is, boxed in by the form of available retailing, by the paradoxical lack of choice brought on by an obsessive belief in "larger is better", and by permissive decision-making that focuses too strongly on the economic benefits of more and larger retail stores. A case study of the retail landscape of Nanaimo, British Columbia is included to illustrate a practical example of this relationship. Drawing on primary research on the impact of shopping locations on individuals combined with in-depth interviews and archival research, the retail landscape is examined. The intended outcome of this research is to challenge local governments, and in particular land use planners, to more fully consider the question of the public good when evaluating land use proposals.

Chronic oil pollution or frequent small-scale oil discharges from vessel operations is an important source of marine oil pollution and considered a constant threat to marine and coastal environments. In Canada’s Pacific region, evidence of such illegal discharges has been gathered by the National Aerial Surveillance Program (NASP) from 1998 to 2007. We used this information to fit Generalized Linear Models (GLMs) for offshore waters and inshore waters and explore the relationships between oil spill occurrences and four predictor variables: shipping traffic densities for different vessel types, distance to shore, distance to port and density of small harbours. The best-fit models for both regions show that areas closer to shore and with higher density of small harbours have a higher probability of oil spill occurrences. However, only in inshore waters was shipping traffic significantly related with oil spill occurrences. Tug boats and oil tanker traffic show a significant positive relationship with oil spill observations, while carriers presented a negative association. Mapped results for offshore areas depicted the highest probability of oily discharges in Barkley Sound and at the entrance of the Juan de Fuca Strait; whereas in inshore waters, oil pollution hot spots were found in the vicinity of major commercial and tourist centres. These probability maps were used to identify Coastal and Marine Protected Areas (CMPAs) and Important Bird Areas (IBAs) more likely to be exposed to chronic oil pollution during a period of 10 years. Three areas were highlighted as the most vulnerable based on their likelihood of exposure and the sensitivity of the species they contain to oil pollution. These sites are the Tofino Mudflats, Barkley Sound, Scott Islands and the Sturgeon and Robert Banks, in the Fraser River delta. Our findings provide better understanding of the relationships between oil spill occurrences and vessel operations and help us identify likely oil pollution hot spots and sites particularly vulnerable to this stressor in Canada’s Pacific region. This information can be useful to NASP in improving its efficiency and in targeting monitoring efforts to troublesome areas. Additionally, this research contributes to regional studies that focus on analyzing the distribution of anthropogenic stressors from sea-based activities in British Columbia. Finally, we highlight the importance of collecting accurate data to properly model the probability of oil spill occurrences and encourage future research aiming to better understand and ultimately reduce the chronic release of pollutants from shipping activities into the marine environment.

In the context of growing concerns regarding global climatic change, developing methods to assess the carbon storage of various ecosystems has become important. This research attempts to develop low or no cost methods to estimate carbon stock in forests using satellite-based data. More specifically, this research explores the utility of spaceborne Light Detection and Ranging (LiDAR) data for forest canopy height and aboveground biomass estimation. High-resolution (sub meter) airborne LiDAR data were collected and validated for a 75 000 ha area near Clearwater, British Columbia. Airborne LiDAR has been widely demonstrated to yield accurate aboveground biomass estimates. 110 temporally coincident Geospatial Laser Altimeter System (GLAS) waveforms from the study site were used in this research. First, I demonstrate that airborne LiDAR can be manipulated to represent waveform curves with a high degree of similarity to GLAS waveform curves. Based on the relationship between the GLAS and simulated waveforms I am able to visualize the ground contribution to GLAS waveforms. Second, I calculate a suite of novel GLAS waveform metrics and develop models of terrain relief, canopy height, and terrain adjusted canopy height. These models compare favourably to other GLAS studies (terrain relief R2=0.76, canopy height R2= 0.75-0.88) and indicate that terrain relief should be included in GLAS derived canopy height models. Third, I attempt to extrapolate the spatially discrete GLAS estimates to spatially continuous estimates using Landsat TM data. Landsat data have been used extensively for AGBM estimation, although they are known to have limitations for studies in high biomass or structurally complex forests. I develop models to predict GLAS AGBM estimates from Landsat bands and indices (R2=0.6). I then use an airborne LiDAR derived AGBM map to generate a map of over and under prediction of AGBM, and evaluate the success of the model in areas of differing forest species and structure. I conclude that GLAS data is appropriate for AGBM estimation in forests over a wide range of biomass values, but that GLAS and Landsat integration for AGBM estimation should only be conducted in forests with less than approximately 120 Mg/ha of AGBM, 60 years of age, or 60% canopy cover.

Au cœur de la Tunisie, la Dorsale Tunisienne se présente comme une succession d'alignements montagneux remarquables, des jbels, qui s'étend du Cap Bon jusqu'à la frontière algérienne. Le problème qui se pose dans la Dorsale vient de la gravité que revêt l'érosion, ne ménageant pas les paysages de celle-ci, actuellement très dégradés. Il s'accompagne d'une politique d'aménagement de conservation des eaux et des sols mise en place par les services publics particulièrement exemplaire dans cette région, tant par la diversité des interventions, que par leur ampleur.<br />L'intérêt n'est pas d'étudier l'érosion en tant que telle, mais les populations face à ces phénomènes. Or, si l'érosion se pose bien à l'échelle régionale, et si les politiques d'aménagement de conservation se conçoivent effectivement à cette échelle, les solutions, elles, ne peuvent être recherchées qu'à l'échelle du paysage, cadre de vie des populations. Est alors analysé le lien entre les perceptions qu'ont les scientifiques et les paysans de ces paysages et de ces milieux, afin de voir si les actions d'aménagements proposées sont susceptibles d'être comprises et reproduites par les habitants. <br />A travers un réseau de petits bassins-versants, suivi par l'IRD et la DG/ACTA, a été développée une approche paysagère fondée sur la segmentation du paysage. A cette analyse du paysage, s'ajoute une recherche sur la représentation et la perception des milieux par les acteurs locaux et étatiques afin de mieux cerner l'intégration ou non des aménagements dans leur cadre de vie.

This thesis describes the geomorphology and morphodynamics of two embayed, sandy, macrotidal beach-dune systems in the Cape St. James region of Gwaii Haanas National Park Reserve and Haida Heritage Site. Gilbert Bay beach is a small embayment with a southwest aspect that exhibits prograding dune ridges. Woodruff Bay beach, a larger system with a SE aspect, is characterized by large erosional scarps on the established foredune. Aspect to erosive conditions and embayment size control the distinct morphologic responses of these beach-dune systems. The morphodynamic regime at Cape St. James consists of high onshore sediment transport potential combined with an increasingly erosive water level regime that is forced by PDO and ENSO climatic variability events. Conceptual models of potential future responses of these beaches to sea level rise show a possible landward migration of up to 3.5 m at Gilbert Bay beach and up to 4 m at Woodruff Bay beach.

The use of hybrid processes med-arb and arb-med continues to grow in both commercial and labour relations contexts. With this growth, there remains a lack of research looking at why a particular hybrid process is chosen or what variables influence individuals to choose one process over another. This exploratory study uses both an online survey of full-time workforce members and semi-structured interviews of experienced hybrid process practitioners to identify and evaluate the variables that influence conflicting parties to choose either med-arb or arb-med. The research findings suggest that two variables, importance of the relationship between the parties and the perceived strength of legal case, are the two greatest indicators of hybrid process selection. Strong support for med-arb is found when disputants place a high value on the importance of their relationship. Arb-med is preferred when relationship is of low importance and strength of legal case is perceived to be high.
