Saturated and near-saturated surface soil hydraulic properties influence the partition of rainfall and snowmelt into infiltration and runoff. The goal of this study was to characterize near-saturated surface soil hydraulic properties and water-conducting porosity in sloping landscapes. The specific objectives included exploration of tension and double-ring infiltrometers for estimation of soil hydraulic properties in sloping landscapes, development of an improved method for determining water-conducting porosity, and the application of these methods in characterizing soil hydraulic properties and water-conducting porosity under three land use. Water infiltration from a double-ring infiltrometer and a tension infiltrometer at water pressures between -2.2 and -0.3 kPa was measured in a cultivated field with 0, 7, 15, and 20% slopes at Laura and under three land use (native grass, brome grass and cultivated) at St. Denis in Saskatchewan, Canada. Three-dimensional computer simulation studies were also performed for tension infiltrometer with various disc diameters, water pressures, and surface slopes. Steady infiltration rates and estimated field-saturated hydraulic conductivity (Kfs), hydraulic conductivity-water pressure relationship (K(h)), and inverse capillary length parameter were compared for different slopes and land use. These parameters were not significantly different (p<0.05) among slopes. For specific K(h) functions, a new analytical solution was developed and compared with existing methods for calculating water-conducting porosity. The new method reliably determined water-conducting porosity of surface soils and gave consistent results, regardless of the width of water pressure ranges. At the -0.3 kPa water pressure, hydraulic conductivity of grasslands was two to three times greater than the cultivated lands. Values of inverse capillary length parameter were about two times and values of Kfs about four times greater in grasslands than in cultivated fields. Water-conducting macroporosity of grasslands and cultivated fields were 0.04% and 0.01% of the total soil volume, respectively. Over 40% and 50% of the total water flux at -0.06 kPa water pressure was transmitted through macropores (pores > 1×10-3 m in diameter) of the cultivated land and the grasslands, respectively. Experimental and simulation results of this study indicated that both tension and double-ring infiltrometers are suitable for characterization of saturated and near-saturated surface soil hydraulic properties in landscapes up to 20% slope. The new method can be used to characterize water-conducting porosity from in situ tension and double-ring infiltrometers measurements more adequately and efficiently than the existing methods. Application of these methods for three land use indicated that land use modified surface soil hydraulic properties and consequently may alter the water balance of an area by affecting the partition between, and relative amount of infiltration and surface runoff.

Using ethnomethodology and influenced by ethnography, the purpose of this research has been to explore the meanings that elder residents in and around Hafford, SK and Val Marie, SK derive from their relationship with and confer upon their cultural landscapes. Hence, for a month and a half, I lived in Hafford and then Val Marie in order to speak with elder residents (age 60 or over) who have lived and worked in or around these areas for at least twenty years.<p>The meanings of elder residents hinge on their memories of growing up and making a living when younger. Their meanings also resonate with the ideas and perspectives that these individuals have formed regarding the changes in their cultural landscape. Changes include those to agriculture; service provision; and the formation of the Grasslands National Park for which Val Marie is the gateway community and Redberry Lake Biosphere Reserve in which Hafford is located. <p>The broad themes of connections, separation, and continuity that I distilled in the narratives of elder residents have guided the identification of the meanings. To this end, the cultural landscape concept has provided an ideal framework. Including the different and diverse meanings of elder residents is integral to our conception of the cultural landscape as a whole, a characteristic that assists in guiding change and development in these communities. <p>In particular, elder residents contribute to an ethical landscape infused with meanings engendered by sentiments of connections, separation, and continuity and ones that hearken to their ethics. Such meanings can have a substantive impact on the decisions influencing these areas. Furthermore, as part of intangible cultural heritage, elder residents offer the meanings they have forged as well as their ethics, the ongoing result of having lived and worked in their cultural landscape. <p>This research has helped to bring relief to the meanings of elder residents in Hafford and Val Marie. Such meanings are necessary in the overall identity of the cultural landscape. The meanings that elder residents derive from their cultural landscape are a valuable asset for communities seeking to maintain their social and economic viability and sustainability.

The present dissertation deals with the artistry of the Swedish artist Vera Frisén (1910-1990). The emphasis is being put on her landscape paintings from Västerbotten, in the northern parts of Sweden, but also includes self-portraits from her early years as a painter. Vera Frisén was born in Umeå, but lived more than half her life in Stockholm. During springtime and summer, she did however return to Västerbotten and the vil¬lages of Stöcksjö and Kolksele, where she painted the majority of her landscape paintings. The study has been given a chronological frame, where the first part sketches out the contexts and environments that came to have an influence on Vera Frisén and her artistic development. Consequently, the thesis starts with a brief biographical presen¬tation, but then moves forward to issues more central to the subject. Important as¬pects are for example her years as a student in the art academy of Otte Sköld in Stockholm during the late 1920’s, and her first separate exhibition at the gallery Färg &amp; Form in 1941. Other issues that are being illuminated in the study are the artistic and cultural conditions in Vera Friséns hometown Umeå. The discussion mainly cen¬ters on issues that took place during the 1930’s and the 1940’s – the time when Vera Frisén established herself as an artist. The second part of the dissertation includes analyses of Vera Friséns paintings. In the search of concepts that further can explain the more profound existential values in her work, the study also links the themes in her paintings to other painters in the his¬tory of landscape painting. Concepts central for discussion are for example the aes¬tethical and philosophical issue of the sublime, as it is formulated in the discourse of Immanuel Kant during the late 18th century. Thoughts expressed by other artists, writers and philosophers, linked to Vera Friséns own thoughts on the subject, are also valuable instruments in gaining a deeper understanding of her work.

The purpose of this research was to determine if the relationship between a community and the nearby provincial park can be enhanced through the use of the cultural planning process. To address the research question a qualitative approach was used which included a case study, a document analysis, a questionnaire and a series of interviews. The subject of the case study was Sandbanks Provincial Park in Prince Edward County, Ontario. The findings illustrated that there are elements and applications of the cultural planning process that can assist a community in efforts to improve or work towards establishing a relationship with its local provincial park. The cultural planning process emphasizes the use of a broad definition of culture and encourages a community to produce an inventory of its cultural resources. This helps to illustrate the value a provincial park contributes to the landscape of an area. The cultural planning process also emphasizes the importance and potential for interaction and communication between different sectors of a community, including the provincial parks. Although Prince Edward County is a leader in cultural planning, it does not yet have a perfectly interactive relationship with its local provincial park. However, the plans, policies, forums and atmosphere produced by the cultural planning have established an environment that is conducive to improving the relationship between Sandbanks and the County. Based on the findings of this research, recommendations have been made to the County, Sandbanks Provincial Park and the Ontario Parks organization. This research will contribute to the literature that exists regarding cultural planning, valuable landscape models and relationships between a community and the nearby provincial park.

Conservation in Canada is increasingly driven by land use planning processes. Approaches to governing nature conservation have shifted dramatically from protecting isolated pristine areas to greater attention to the remaining fragments of greenspace in urban, semi-urban and rural areas. The ways that societies govern and use nature are always changing, and these physical management actions are connected to deeply rooted cultural norms and values about the ideal relationship between humans and nature. In the land use planning approach to conservation, citizens and governments find value and construct meaning for remaining nature rather than beginning with normative considerations of what is most worthy of protection. At the root of this conservation planning trend is a growing appreciation for hybrid nature that is valued as natural in spite of the past or present influences upon it. This represents a dramatic shift from the traditional values involved in North American nature conservation, where nature was most valued for its perceived separation from human influence and protected to maintain its untouched qualities. In light of these ideological shifts in the ways that Canadians value and in turn manage nature, is there a corresponding change in the ways that conservation activists perceive environmental value and evaluate naturalness? An increasing number of studies demonstrate that public valuation of nature is not limited to pristine environments: even highly disturbed environments can be valued as natural and are not perceived as a form of lesser nature. Conceptions of what is natural and what is not are highly subjective and variable; in particular, the body of work on the social dimensions of both invasive species and ecological restoration demonstrates the ways in which people construct naturalness in accord with their values and cultural context. By exploring the extent to which people perceive invasive species as reducing naturalness and how ecological restoration is perceived to restore it, these subjects serve as excellent conceptual lenses for exploring constructions of nature. This study explores the subtle variations in environmental values and perception of naturalness among a study population who self-identify as pursuing the same goal: ensuring the continued protection of the Oak Ridges Moraine. The Moraine is a partly urbanized landform in southern Ontario that is situated within a complex hybrid socio-ecological landscape. It is also the subject of an active and high profile conservation movement that has spanned over 40 years. Using a combination of interviews and Q Method, this study explored how citizens engaged in Oak Ridges Moraine conservation perceive both the current and ideal state of naturalness on the Moraine, with specific emphasis on how the discourses these citizens use to frame the Moraine invoke the concept of naturalness Findings from this study reveal that Moraine activists represent a conservation paradox: they value the natural, non-human qualities of the landform, yet at the same time identify the Moraine as a hybrid landscape with both social and ecological qualities. In particular, respondents indicated a strong interest in naturalness in the context of invasive species and ecological restoration, yet at the same time identified the naturalness of the Moraine to be a lesser priority in the face of urban development pressures. In this way, citizens engaged in Moraine conservation respond to the hybrid quality of the Moraine landscape by moving beyond the binary distinction between nature and society, situating themselves as both apart from and a part of the landscape at the same time. This finding demonstrates how values for conserving nature are affected by hybridity between social and ecological systems, and suggests how embracing the paradox of hybrid nature can contribute to understanding and managing complex socio-ecological systems.

In an era of dawning anthropogenic climate change, people of atoll nations face grievous threats to their future. Rising sea levels, warming oceans, and changing weather patterns conspire with economic isolation, rapidly growing populations, and the loss of traditional livelihoods to perpetuate conditions of dependence and wardship which threaten the very existence of their island homes. This project examines an atoll nation of the equatorial Pacific, the Republic of the Marshall Islands, where the outward appearance of pristine tropical paradise belies a tragic history of nuclear weapons and ballistic missile testing at the hands of the US military. While the islands have been consistently framed in rhetoric which stresses vulnerability, smallness and unsustainability, this project contests the limited scope of the regimes of power in Oceania by considering how the independent, grassroots actions of local groups of islanders have achieved surprising and dramatic results in defiance of the policies and planners at the top. In developing a design proposal for the contemporary condition, this thesis examines the persistent ways in which the islands and people are framed by outsiders. This project engages with the social, political and natural history of the atolls: common tropes are challenged by the actions and agency of a people who have dealt with imperialist outsiders in sophisticated and conscious ways. It explores the traditional cultural practices which enabled the ancestors of the Marshallese people to flourish, and suggests that it is at the level of actions by ordinary people that the most fertile potentials lie, and are in fact already being played out. What forms of urbanism might be appropriate in this environment? How can islanders effectively manage their landscape and engage with the natural processes - as their ancestors once did to a remarkable degree? By pairing traditional techniques with modern technologies, a proposal is synthesized which could empower the contemporary Marshallese to transform their landscape and develop sustainable livelihoods in this extreme and dynamic environmental condition: to build a future which offers the best aspects of both traditional and contemporary ways of life.
