The thesis examines land-use changes in a selected area of the Niagara Fruit Belt between 1954 and 1978. Part of the former township of Louth was chosen for investigation because it is located in the centre of the fruit belt, and is an area affected by several urban influences. Two detailed land-use maps were produced from aerial photograph interpretation. These maps reveal the many exchanges among agricultural land uses and the actual loss to urban and urban-related uses which occurred during the time span investigated. They indicate the loss of fruit land to non-agricultural uses is less than was anticipated. Increases in grape acreages have been implemented relatively close to the city of St. Catharines and the lost peach acreage is not entirely due to urbanization. A land-use change index was developed, based on total change per lot, for use in the quantitative analysis. The 1954 assessment roll provided the data on individual properties. Eight hypotheses were developed to account for the land-use changes. These were rejected, and it was suggested that the study area was undergoing a "normal” process of change, resulting from a combination of agricultural and urban forces. Further research is needed in order to understand more fully, the processes of land-use change in an area such as Louth. / Thesis / Master of Science (MS)

Most land use plans and policies, including those concerning growth management, are created in urban hubs (Afshar, 1994; Summer, 2005). My interest in this thesis started by asking the question: What are the criteria that ensure that land use plans and related policies serve rural livelihoods and stewardship under the lens of sustainability and resilience? Being a citizen residing in Niagara Region, I was inspired to find out the criteria to judge plans and policies in rural Niagara as a case study. This thesis uncovers the categories of consideration for rural areas close to urban centres in developed countries, and the context-specific criteria pertaining to rural Niagara. The eight context-specific categories, merged with sustainability and resilience imperatives, are presented as evaluation criteria in a brief form as follows: 1. Plans and policies should provide for building communities’ capacity in participative and collaborative governance including overlap in governance; 2. provide means for reconciling different interests in a way that celebrates diversity and ensures sufficiency and opportunity for all towards intragenerational equity while supporting community solidarity to acknowledge slow variables and feedback signals; 3. provide for the support of viable farming by fostering livelihood sufficiency and preserving resources for future generations within a regional character; 4. provide for strengthening the socio-economic base integrity in ways that also maintain/ rehabilitate the socio-ecological base by reducing threats to its long-term integrity while encouraging diversity and innovation. 5. Plans and policies are to be used as tools to reduce intragenerational and intergenerational inequities in livelihood sufficiency and opportunity through collective responsibility, and innovative solutions to the local poverty problems. 6. Plans and policies should allot specific clauses to alleviate land stressors through institutionalized adoption of the precautionary principle, socio-ecological system integrity and the application of all sustainability imperatives while rewarding voluntary stewardship. 7. Plans and policies should acknowledge and foster multi-functionality in agriculture as one of the means to foster livelihoods, socio-ecological system integrity, and sustainable use of resources through the integration of all sustainability imperatives. Multi-functionality entails fostering diversification, the building of a regional modular character while acknowledging slow variables and system feedbacks through innovative local solutions 8. Plans and policies should cater for Preparedness for the Future by institutionalizing the adoption of precaution and adaptation as one of the means to prepare for uncertainty and applying all sustainability imperatives to seek mutually supportive benefits while nurturing a resilient Niagara character through all resilience imperatives The above eight categories relate to all the sustainability imperatives (listed in appendix C) and all the resilience imperatives (listed in appendix D) in various ways. The research used the technique of triangulation for corroborating evidence. By reviewing a purposeful sample of Niagara government and non-government documents, the presence of the eight categories was confirmed. A sample of articles in a local paper also confirmed the presence of the categories. By counting the number of mentions for each category, the priority order was inferred. In the case of Niagara the top priority is given to “Viable Farming” as concerns grow over the mounting challenges faced by family farms. “Stewardship” is the second priority to enable the rural and farming communities to play the role of land stewards.

A review of the history of the nomenclature of the Medina Formation and of the previous studies of its members, particularly those studies dealing with the source of the Whirlpool sandstone. This is an attempt to show the direction of origin of the detrital materials of the Whirlpool sandstone by a study of the lateral variation of its grain size along the Niagara Escarpment. It is illustrated with maps and with photographs taken by the writer. / Thesis / Master of Science (MSc)

The stability of the Niagara Escarpment is of critical importance to residents of Hamilton, Ontario as it bisects and divides the lower downtown core from upper residential and commercial areas. The frequency of large rockfalls and debris slides from the exposed escarpment face has resulted in reoccurring road closures that connect these two areas and has prompted the city to seek information on the processes affecting escarpment erosion and slope stability. The research reported here examines the relationship between tree and plant growth on bedrock stability by investigating relationships between species abundance and slope profile, and the potential movement of tree roots growing in rock fractures. The contributing factors of tree growth to physical weathering processes on highly fractured bedrock remain largely unknown; however, plants are suggested to play a key role in weathering processes in the critical zone. Bedrock structure and lithology influence the establishment of vegetation, and vegetation in turn exploits bedrock joints, fractures, and bedding planes, exacerbating physical and biomechanical weathering processes. In this study, vegetation characteristics observed on different parts of the escarpment face were documented and categorized into three distinct biophysical zones: upper and intermediary plateau, bedrock face, and sloping talus. Tree growth, with the potential to enhance bedrock disaggregation through the transfer of tree bole movement to roots exploiting bedrock fractures, was particularly prevalent on areas of sloping talus. To document the potential for bedrock disaggregation through tree bole movement, triaxial accelerometers were mounted on the boles of three different tree species growing along the escarpment in Hamilton. Sampled trees varied in geographic location to allow identification of the relationship between tree bole movement, wind speed, and dominant wind direction. Both deciduous and coniferous species were monitored to determine the impacts of canopy architecture on tree sway in response to wind. Monitoring took place over several days in the months of March, May, September, and November. Recorded tree bole movement (tilt) varied between deciduous and coniferous tree species; wind speed was strongly correlated to tilt of the coniferous tree, and wind direction was strongly correlated to tilt of the deciduous trees. Overall tree bole movement was strongly influenced by diurnal cycles of air movement and was greatest in the hours around mid-day. The outcomes of this research will form an integral component of an erosion-risk assessment study conducted, in part, for the City of Hamilton and will facilitate the design and development of vegetation management strategies for the Niagara Escarpment that may reduce erosion processes and potential damages to impacted citizens and businesses. / Thesis / Master of Science (MSc) / This research examines the impact of vegetation growth on erosion processes on the Niagara Escarpment in Hamilton, Ontario. The slope of the escarpment face exerts an important control on vegetation growth which in turn affects slope stability. Documentation of the dominant vegetation species at two research sites allows the identification of three distinct vegetation zones on the upper plateau, bedrock face, and sloping talus. The movement of tree trunks in response to air movement was also measured for several days in the months of March, May, October and November. Results show that the movement of two monitored deciduous trees was most strongly correlated to wind direction, while the movement of a coniferous tree was strongly correlated to changes in wind speed. All monitored trees were strongly influenced by daily cycles of air movement which were greatest around noon. This research identifies factors that influence both vegetation growth and slope stability on the Niagara Escarpment and may be used to develop effective erosion protection and mitigation strategies.
