Impact of the Kenow wildfire on the form and mobility of particulate phosphorus in gravel-bed rivers at large basin scales: Implications for downstream propagation
(University of Waterloo, 2022-05-25)Landscape disturbance by wildfire in forested source water regions can significantly accelerate fine sediment transport from hillslopes to receiving streams. The mobilization of fine sediment and associated nutrients, such ... -
The impacts of cash transfer programs on rural livelihoods: a study of Caboclos in the Brazilian Amazon estuary region
(University of Waterloo, 2016-08-25)Rural households that rely on agricultural and natural resources for their livelihoods have been exposed to increasing socio-economic and climatic challenges over the past few decades, which requires urgent scientific ... -
Impacts of Climate Change and Controlled Tile Drainage on Water Quality and Quantity in Southern Ontario, Canada
(University of Waterloo, 2018-09-06)Within the Great Lakes region, agricultural non-point source nitrogen (N) and phosphorus (P) contamination contribute to algal blooms and decreased water quality, particularly from tile-drained landscapes. These water ... -
The Impacts of Diamond Mining to Peatlands in the James Bay Lowlands
(University of Waterloo, 2013-02-21)Approximately 7000 to 8000 years ago when Hudson Bay became ice-free the Tyrrell Sea flooded the Hudson basin and deposited fine grained marine sediments overlaying the previous glacial tills. Coincident with the ablation ... -
Impacts of freeze-thaw processes on phosphorus release from a variety of cover crop species in a temperate climate
(University of Waterloo, 2018-04-30)Cover crops (CC) are grown by farmers as an agricultural best management practice (BMP) to improve soil health during the non-growing season (NGS), and potentially reduce soil erosion. Some managers have cautioned against ... -
Impacts of historical and projected climate changes on ice surfaces of the Tibbitt to Contwoyto Winter Road, Northwest Territories, Canada
(University of Waterloo, 2014-10-27)Seasonal ice and winter roads are a historically important part of the Canadian arctic transportation network. Constructed over frozen lakes, rivers, permafrost zones, and seasonally frozen ground, the roads service rural ... -
Impacts of resource access road crossings on ecohydrology and carbon dynamics of boreal peatlands
(University of Waterloo, 2019-09-04)Resource access road crossings are expected to alter peatland ecohydrological properties by obstructing surface and sub-surface water flows, providing favorable conditions to stimulate microbial activity, and ultimately ... -
Impacts of seismic line restoration on CO2, CH4, and biomass
(University of Waterloo, 2021-10-21)Oil and gas exploration has resulted in over 300,000 km of linear disturbances, known as seismic lines, throughout boreal peatlands across Canada. Sites are left with altered hydrologic and topographic conditions that ... -
Impacts Of Seismic Line Restoration Techniques On Nutrient Biogeochemical Processes In A Boreal Fen
(University of Waterloo, 2021-12-23)Peatlands contain 40 cm or more of partially-decomposed plant matter and sequester carbon and nutrients. The disturbance of peatlands alters these ecological functions. Seismic lines, long cutlines in the forest created ... -
Implementation of a GIS to Assess the Effects of Water Level Fluctuations on the Wetland Complex at Long Point, Ontario
(University of Waterloo, 2003)The Long Point wetland complex is one of the most significant coastal wetland systems in the Great Lakes, containing a diverse mosaic of wetland vegetation communities that have developed in response to water level ... -
Implications of Low Water Levels for Canadian Lake Huron Marina Operations
(University of Waterloo, 2010-01-06)Recreational boating in the Great Lakes is suggested to fuel tourism and the Ontario economy. Like many other tourism sectors, boating-tourism is a highly climate-sensitive economic sector which significantly relies upon ... -
The Implications of Sea-level Rise for Tourism in St. Lucia
(University of Waterloo, 2013-06-21)Sea-level rise is one of the most certain impacts of climate change that will have major long-term implications for tourism in the Caribbean. Sea-level rise will impact coastal tourism through inundation and erosion, damage ... -
The Importance of Institutional Arrangements for Sustainable Livelihoods: The Case of Tun Sakaran Marine Park, Sabah, Malaysia
(University of Waterloo, 2015-09-11)Although there has been growing research examining ecotourism from a livelihoods perspective, there is still lack of explicit and critical analysis of how people relate to the institutional environment, where power lies, ... -
Improving estimates of net ecosystem CO2 exchange between the Arctic land surface and the atmosphere
(University of Waterloo, 2013-05-24)Feedbacks between the climate system and the high-latitude carbon cycle will substantially influence the intensity of future climate change. It is therefore crucial that the net ecosystem exchange of CO2 (NEE) between ... -
In Debt to the State: Lived Experiences of Indebtedness in State-led Housing Projects in Istanbul
(University of Waterloo, 2022-06-17)Over the last couple of decades, global debt has soared. Withdrawal of state welfare provision, expansion of financial markets, and dependency of people on credit for basic needs have led to increased indebtedness. Household ... -
Inequalities in Health and Wellbeing Among Elderly Populations: A Case Study of Central Uganda
(University of Waterloo, 2019-09-23)Sub-Saharan Africa (SSA) has the fastest aging population in the world. Yet its older population has the lowest life expectancy, lowest ratings of subjective wellbeing, and greatest burdens of disease in old age globally. ... -
Influence of Antecedent Soil Moisture and Rainfall Rate on the Leaching of Nitrate and Phosphate from Intact Monoliths of Agricultural Soil
(University of Waterloo, 2010-05-18)The export of nitrogen (N) and phosphorus (P) from agricultural catchments is a major problem worldwide. The export of these nutrients is largely driven by storm events, and the hydrologic response of catchments varies ... -
Influence of graminoid species identity on carbon exchange in a restored peatland in central Alberta, Canada
(University of Waterloo, 2017-09-27)Peatlands are globally important ecosystems for carbon sequestration. Commercial extraction of peat layers alters the ecosystem services provided by pristine peatlands. One metric of peatland restoration is recovery of ... -
The influence of peat volume change and vegetation on the hydrology of a kettle-hole wetland in Southern Ontario, Canada
(International Mire Conservation Group and International Peat Society, 2007-12)Links between local hydrology and vegetation type exist in wetlands, yet it is unclear what role peat volume change plays in these interactions. We measured peat volume change and hydraulic conductivity (Kfield) at three ... -
