Economic development in the declining Maritime Provinces has proven to be an intractable problem over the last 70 years. Efforts have ranged from capitalist industrial resource extraction to worker-owned producer co-operatives. Yet, throughout its many variations, these initiatives have done little to secure the long-term economic security of Canada’s most marginalized rural communities, such as those on the western coast of Cape Breton Island. Efforts toward this end during the closing decades of the twentieth century, up to present date, have applied market-led development strategies paralleling trends in the increasingly fluid global market economy. This local economic development approach, it is argued, reinforces economic dependency established during the last century’s staples commodity extraction, even as it attempts to reduce it and promote communities’ unique socio-cultural values, through ‘local ownership’ of integration into the market economy. An analysis of conventional approaches to economic development and ‘local ownership’, that focuses on two communities in rural western Cape Breton, demonstrates this point. Several alternatives to conventional economic development are considered, with a particular emphasis on the two Cape Breton communities.

This research evaluates the decomposition of leaf litter while in litter traps. More specifically this study asks, ‘Does sugar maple (Acer saccharum Marsh.), American basswood (Tilia Americana L.) and American beech (Fagus grandifolia Ehrh.) leaf litter collected bi-weekly from litter traps undergo a loss of dry mass and nutrient content (C, N, P, K, Ca and Mg) in comparison to freshly abscised leaf litter?’The objective of the initial experiment was to determine if sugar maple, basswood and beech leaf litter collecting in litter traps, while exposed to in-situ conditions, experienced decomposition. Results indicated that sugar maple, basswood and beech leaf litter experienced early stages of decomposition and identified precipitation, freezing temperatures and microbial activity as possible mechanisms for the observed decomposition. It was found that the dry weight of sugar maple and basswood differed significantly (p < 0.05 and p < 0.10, respectively) post- 14-day experiment period as compared to the initial dry weight. Consequently, three experiments were completed to examine the aforementioned variables. Conclusions were based on measured changes in the mass and nutrient (C, N, P, K, Ca and Mg) content of freshly abscised sugar maple, basswood and beech leaf litter under ex-situ conditions. It was found that the dry weight sugar maple and basswood leaf litter exposed to 30 mm, 60 mm and 100 mm of precipitation differed significantly (p < 0.05) as compared to freshly abscised leaf litter. In general, this research affirmed that precipitation and freezing temperature contribute to a change in mass and nutrient content of leaf litter collecting in litter traps. Furthermore, through measurable production of CO2 and Community Level Physiological Profiling it was determined that microbes are present and active on the leaf surface and contribute to the decomposition of leaf litter in litter traps.

Through appropriate soil and crop residue management, soil can function as a sink for carbon (C) and nitrogen (N) for the mitigation of greenhouse gases (GHG). No research has yet investigated the potential of intercrop agroecosystems to reduce emissions of GHG to the atmosphere. This research evaluates whether maize-soybean intercrop agroecosystems sequester more C and N and emit fewer GHG than maize and soybean sole crop agroecosystems. An experiment was conducted at Balcarce, Argentina using four treatments: a maize sole crop, a soybean sole crop, and two intercrops with either 1:2 or 2:3 rows of maize to soybean. The objectives were to quantify soil organic carbon (SOC) and soil total nitrogen (TN) at 0-10, 10-20, 20-40, 40-80 and 80-120 cm depths, rates of decomposition of maize and soybean crop residue after 312 days, crop residue C- and N-input at harvest, and emissions of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Significant decreases in SOC were observed with depth in all treatments after 40 cm, and significant decreases in TN were observed with depth in all treatments after 20 cm. Crop residue from maize had the greatest input of C and N to the soil, but the slowest rate of decomposition. Soybean biomass had the least input of C and N to the soil and the fastest rate of decomposition. The 1:2 and 2:3 intercrop agroecosystems had moderate crop residue inputs of C and N and intermediate rates of decomposition. No significant differences in GHG emissions were detected between treatments throughout the growing season. The major influences on GHG emissions were weather events, soil temperature and moisture, and crop residue input. Annual GHG emissions were determined; the CH4 sink in the 1:2 intercrop and the soybean sole crop was significantly greater (P < 0.05) than the 2:3 intercrop and the maize sole crop. Emissions of CO2 were inversely proportionate to N2O, with the greatest C sink in the 1:2 intercrop.

Generation of solid waste is a problem of great environmental significance in the Mexican Federal District. With an estimated daily generation of 12,500 tons waste management is a priority for the district government. Through the launch of a new initiative known as ‘Green Plan’, the government is proposing to implement an integrated waste management system that will not only reduce the amount of waste sent to landfills, increasing reuse and recycling of waste, but also will allow the district government to realize economic gains by charging a fee for collection services and selling energy generated from incinerating waste. Integrated waste management programs have been implemented in the Mexican Federal District in the past. They have failed. This research has examined the most recent initiative in an effort to discover the causes of failure, using a case study approach. In addition to identifying barriers to and opportunities for implementation of an effective integrated waste management system in the Federal District, this research recommends options for the newly proposed waste management system that will achieve the objectives desired by the government, while aiding in the pursuit of sustainable development. The research has revealed that the performance of the Federal District’s Integrated Solid Waste Management Program, or any other program of the sort, is affected mainly by a combination of factors that are under the local government’s control: legal instruments, administrative organization and political conflicts, allocation of resources, education and training, and citizen participation. Strengthening these areas will improve the performance of the program. In comparison to much of the existing waste management literature that aims at identifying opportunities for supporting proposed systems through technological innovation (Chambal, et.al., 2003; Eriksson, et.al., 2005; Hung, et.al., 2007), this research has found that key barriers and opportunities lie in the strengthening of the institutional capacities of the local government. While recommendations of this study have been developed within the specific context of Mexico City, they may offer some more general guidance about how to respond to concerns which are likely to apply to many other large urban municipalities in developing countries. Application of the Gibson principles for sustainability in the context of Sandra Cointreau’s guidelines for sustainable waste management has provided a useful evaluation guide. This research has focused not just on evaluation of a particular waste management system, but also on the geographic and administrative context of the system in order to gain a broader insight into the factors over and above technical standards and mechanisms that affect the performance of the system.

This thesis examines the feasibility of fostering “sustainable foodscapes” in urban communities. A review of the literature on the topics of sustainability, resilience, sustainable food security, and healthy communities is used to determine to the definition of “sustainable foodscapes.” This thesis uses a framework of socio-ecological restoration to consider how communities might adopt sustainable foodscapes. A case study is conducted in the city of Waterloo, Ontario to test the criteria of sustainable foodscapes and explore some of the practical opportunities and barriers to developing sustainable foodscapes in an urban community. The methods for the case study include semi-structured interviews. Interview results indicate that a variety of sustainable foodscapes such as community gardening, individual gardening, and foraging are used in Waterloo already, and survey results suggest that various members of the community are open to the adoption of these foodscapes. The case study results reveal that diverse community members view sustainable foodscapes as an important contribution to community health, less for the purpose of ecological sustainability than for their usefulness as a way of promoting community interaction, social learning, and fostering a sense of place. Ways to conduct a socio-ecological restoration for sustainable foodscapes in Waterloo could include increasing areas for the purposes of foraging to occur in an ecologically benign manner, such as on marginal or private land; creating municipal policies and Official Plans that provide support for community gardens, and fostering more accepting attitudes towards sustainable foodscapes by providing increased opportunities for education and participation among community members.

The water soft path (WSP) has been formulated as a progressive paradigm in water management. The WSP has four main principles: water should be viewed as a service; ecological sustainability is of utmost importance; water quantity and quality should be conserved; and planning should be done from the future backwards, not projected from the present. It may be possible to use conservation-based water pricing programs, especially at the residential level, in order to incrementally implement the WSP. Moreover, the implementation of residential seasonal water rates has been suggested as a method to curb peak demand in municipal water systems, thereby deferring infrastructure expansion. The purpose of this thesis is to answer the question: what are the barriers to implementing residential seasonal water rates in the Region of Waterloo? This question is addressed using a variety of data sources, with the majority of the information coming from academic and non-academic literature, and from interviews with water professionals and local councillors. The results provide a descriptive case study concerning the barriers to implementing seasonal water rates in one particular region of southwestern Ontario, but the conclusions can be generalized to describe some of the barriers to the implementation of seasonal water rates in Ontario. Results suggest that some barriers are more severe than others, and that the more serious ones may be addressed by: expounding the potential for seasonal water rates to curb peak demand; carefully designing a rate study to be administered with non-price programs; and implementing the designed rate structure as a pilot study. It is suggested that the implementation of seasonal water rates can be used as an incremental step towards the adoption of WSP principles, but not without first envisioning a desirable future.

As Canada employs a federated system of government, there are separate environmental assessment (EA) processes. In Ontario, Canada, there is a streamlined, pre-approved, self-assessed process (i.e., the Minister of the Environment’s approval is not required) for “classes” of projects. These Class EA projects are routine, with known impacts, being predictable and mitigable, in a southern Ontarian environment. However, it is assumed that Class EA protocol developed in the southern Ontarian context is directly transferable to northern Ontario. A case-based approach, using the Victor Mine electricity transmission line project, was employed to critically examine whether the Class EA template developed in southern Ontario, could be effectively applied to the western James Bay region of northern Ontario. Specifically, the two assumptions (and corollaries) of Class EAs of predictability (corollaries: the environment is similar in all locations where Class EAs are applied; and the environment is well understood) and mitigability (corollary: all negative effects are mitigable) were examined. Primary (semi-directive interviews) and secondary (literature search) data were used to inform a themed analysis. Results indicate that the northern environment is unique: biophysically, the western James Bay area is Ontario’s only salt water coastal region, and contains one of the largest wetland regions in the world; and socio-economically, no southern Ontarian region can claim that one third of their total regional economy is related to subsistence pursuits. In addition, the northern environment is dynamic, disproportionately changing over time with respect to climate change and post-glacial isostatic adjustment. Moreover, not all negative effects are mitigable (i.e., the effects the existing electrical transmission line has had on waterfowl harvesting). Thus, the Class EA template is not transferable to the northern Ontarian context. Similarly, in other northern regions of the world where glacial isostatic adjustment is a reality and these regions uniqueness must be recognized and be reflected in the EA process, if a process exists.

Protected areas are considered to be the cornerstone of biodiversity conservation strategies and are valued sources of human well-being and ecosystem services. Yet they are not immune to the unprecedented impacts being felt worldwide. As an example, increased human activity, including development, transport of invasive species, and contributions to climate change, are transforming protected areas within the Laurentian Great Lakes into new and novel ecosystems. It is in this context of uncertainty that I explored the practice of managing for resilience. Canada’s first national marine conservation area, Fathom Five National Marine Park in Lake Huron, functioned as the study area. Besides profound and complex ecosystem change, Fathom Five is also experiencing governance challenges in the form of tangled responsibilities and issues of legitimacy. The resilience-based approach recommended elements that strengthened the capacity of the park to cope with and recover from disturbance and maintain its defining structures, functions, and feedbacks. This included a reduction of vulnerabilities (e.g., limit exposure to coastal fragmentation, manage disturbance regimes, and maintain functional and response diversity), an increase in adaptability (e.g., need to foster social learning, innovation, and improved governance structures), and an ability to navigate change (e.g., better express desired state, identify thresholds, and influence transformations), within established management practices. More specifically, methods to make spatial planning and monitoring more operational and resilience-based, were developed. For spatial planning, the decision-support tool Marxan with Zones was utilized and demonstrated how themes of representivity, replication, and connectivity could be applied in a resilience-based zoning context. For monitoring, a multivariate distance-based control chart method was developed to detect a decrease in resilience of the parks coastal wetland fish communities. Although an increase in variability was observed, a regime shift was not reported during the years investigated (2005-2012). In summary, the thesis provided an original contribution to science by examining the uncertainties and complexities facing a freshwater protected area and reframing practical conservation solutions through a resilience lens.

In a world where food production is sufficient to feed everyone, more than 850 million people live in conditions of undernourishment, hunger, or starvation. Much of the problem lies in the current dynamics of the global agri-food system; they have impaired access to food and contributed to environmental damage and social disintegration. This increasingly integrated global system is displacing family farming enterprises in favour of agro-industrial monocultures, with their associated consequences for ecosystem health (biodiversity loss, heavy reliance on fossil fuels, etc.), and in the degradation of traditional food cultures. Conventionally, the term “food insecurity” is used to describe situations of food deprivation. This study, however, adopts a broader perspective on the issue. It has associated the ideas of food security with those related to healthy food systems, suggesting that it is not only important to strive for universal access to adequate food but also to think of the means and processes by which it can be achieved; that is, a food system that promotes equity and environmental sustainability. In addition, food security also emphasizes the need for a healthy and active life unimpaired by overconsumption or inadequate eating habits. Using a systems perspective, this study has devised criteria of sustainable food security, which serve as indicators of health in the food system. These criteria include nutritional and cultural adequacy of food, physical and economic access to it, the setting in which it is offered (i.e. the “food environment”), and the food systems’ social and biophysical impacts. Such criteria were applied to two case studies: first in Canada (Waterloo Region, Ontario) and then in Brazil (Feira de Santana, Bahia), two very different contexts, but both under the influence of global agri-food dynamics. With this case study analysis, this research investigates the current challenges for achieving sustainable food security in local communities, as well as opportunities and benefits that might be available. Feira de Santana exhibits great agro-biodiversity, a very localized food system, and community initiatives to support local food traditions, family agriculture, and sustainable farming practices based on agroecology. These efforts, however, are hindered by poverty, lack of education, poor infrastructure, and little support from the local government. For its part, Waterloo Region counts on a very supportive government that strengthens local food initiatives and combines efforts with non-state organizations in order to promote a healthy food system. Despite possessing notable local food traditions, its food system is much more globalized than Feira de Santana’s. Most of its food is imported, and much of the arable land is used for agro-industrial cash-crops. This has hampered the operations of the smaller local farmers, damaged the environment (due to long transportations and intensive, conventional agriculture), and contributed to poor eating habits. Although Waterloo Region faces less food deprivation than Feira de Santana, it has a much bigger problem with respect to overconsumption and obesity – half of the local population is overweight with associated health concerns. In conclusion, this study stresses the need to consider food security from a systems perspective, taking into account social and environmental factors. Thus, it highlights the need to promote sustainable food systems, and draws some recommendations for achieving it.
