Investigating The Mobility Of Arsenic In Subarctic Mining Pollution-Affected Peatlands Near Yellowknife, Northwest Territories, Jeremy Leathers

Theses and Dissertations (Comprehensive)

Arsenic (As) is a pollutant of global concern that is detrimental to human and environmental health. Between 1948 and 2004, mining operations near Yellowknife, NT released over 20,000 tonnes of As trioxide (As₂O₃) that continues to persist in the surrounding landscape. Although much effort has been put into studying the chemical forms, spatial distribution, ecological impacts, and environmental cycling of As in the area, more work is needed to determine the controls of As mobility between the terrestrial and aquatic components of the landscape. Soils are known reservoirs of legacy As that can release it downslope …

Assessing Stormwater Management Pond Water Quality, Function, And The Potential Biotic Effects To Receiving Waters, Mitchell Elstone

Theses and Dissertations (Comprehensive)

The use of stormwater management ponds (SWMPs) has been increasing over the past five decades. However, an in-depth understanding of the daily performance of SWMPs and functionality during cold periods is limited. This is in part because mandated monitoring is relatively infrequent, and the assumption that SWMPs are inactive between storm events and during the winter. The goals of this research were to better understand daily stormwater (SW) characteristics, the performance of SWMPs based on current forms of evaluation and assess the potential for SWMP effluent to impact downstream biota. Influent and effluent samples from two SWMPs were collected daily …

Mapping With The Land: Co-Developing A Cumulative Impact Monitoring And Land Stewardship Framework With Sambaa K’E First Nation, Northwest Territories, Canada, Michael S. Mcphee

Theses and Dissertations (Comprehensive)

Across the Northwest Territories (NWT), Canada, Indigenous populations are striving to achieve effective environmental protection, whilst navigating complex methods, policies, and research relationships within co-management contexts. This thesis seeks to identify how differing cultural systems, environmental change, and fractured partnerships may be unified to align with the needs of the Sambaa K’e First Nation (SKFN), a remote Dehcho Dene community. Indigenous methodologies guided co-development of research questions with SKFN leadership which yielded objectives a) develop a GIS-based method to manage, organize and mobilize cultural and environmental data; b) develop a new stewardship monitoring procedure so that users can apply the …

Winter Dynamics Of Storm Water Management Ponds And Winter Tolerance In Three Aquatic Plant Species, Patrick Strzalkowski

Theses and Dissertations (Comprehensive)

The vast majority of the research into the performance of stormwater management ponds (SWMPs) has been performed in warm regions or during the warmer seasons in temperate regions. It is presumed that SWMPs are inactive in the winter as any potential stormwater is trapped in snow and ice. The main goal of this thesis was to test this presumption and to study the dynamics and performance of three SWMPs during the winter. Remote water level loggers were installed into the three SWMPs and daily grab samples from the influents and effluents were taken and analyzed for total phosphorus (TP), chloride, …

Assessment Of Stream Metabolism And Associated Environmental Drivers In The Greiner Lake Watershed, Nunavut, Canada, Nicole Gotkowski

Theses and Dissertations (Comprehensive)

Stream metabolism is an ecological process that can be monitored to assess carbon cycling and productivity within a stream ecosystem. GPP (gross primary productivity) is measured as oxygen produced by autotrophs and ER (ecosystem respiration), which is measured by oxygen depleted by all living organisms. Complications arise when estimating GPP and ER in the Arctic because most methods require a period of darkness when GPP ceases, however, summer regimes of photosynthetically active radiation (PAR) do not reach zero. Furthermore, natural diffusion of oxygen from the atmosphere (k) must be accounted for but this requires extensive field work, thus posing problems …

Contrasting Seasonal Cycling Of Arsenic In A Series Of Subarctic Shield Lakes With Different Morphometric Properties, Jeremy Harbinson

Theses and Dissertations (Comprehensive)

The subarctic shield near Yellowknife, Northwest Territories (NWT), is populated with thousands of small lakes (<1.5 km²) and several large lakes. Historic mining activities in the region have left a legacy of environmental impacts and widespread arsenic (As) contamination in both aquatic and terrestrial environments. In particular, several small subarctic lakes near Yellowknife have been previously documented to be contaminated with high levels of As. Subarctic lakes are characterized by seasonal ice-cover that can persist for more than half of the year, yet little is known about the under-ice spatial and seasonal dynamics of As cycling. The objective of …

A Machine Learning Approach To Classify Open Water And Ice Cover On Slave River Delta, Ida Moalemi

Theses and Dissertations (Comprehensive)

Seasonal temperature trend and ice phenology in Great Slave lake (GSL), are strongly influenced by warmer inflow from Slave river. The Slave river flows to GSL through Slave river delta (SRD), bringing a rise in temperature that triggers the ice break-up process of the lake. Slave river discharge is subject to multiple stressors including climate warming and upstream water activities, which in turn, directly affects the GSL break-up process. Consequently, monitoring the break-up process at SRD, where the river connects to the lake, serves as an indicator to better understand the cascading effects on GSL ice break-up. This research aims …

Nitrogen: Both A Potential Stimulator And Suppressor Of Cyanobacterial Blooms In Temperate Lakes, Catherine Goltz

Theses and Dissertations (Comprehensive)

Cyanobacterial blooms are complex phenomenon that are impacted and controlled by various factors such as lake depth, air temperature, wind, and nutrient loading. Nutrients such as phosphorus, nitrogen and iron all have very differing effects on cyanobacterial blooms. While phosphorus and iron are known to drive cyanobacterial biomass, nitrogen has been observed to have a direct impact on toxin synthesis. Nitrogen exists in the environment in many different forms such as atmospheric N₂, in inorganic forms such as nitrate and ammonium as well as in organic forms such as urea which can all affect cyanobacterial bloom development differently. …

The Dynamic Relationship Between Permafrost And Landcover In Northwestern Canada’S Discontinuous Permafrost Zone, Olivia Carpino

Theses and Dissertations (Comprehensive)

Northwestern Canada’s subarctic is among the most impacted regions in the world as it is experiencing rapid climatic and environmental change. As a result, northwestern Canada has been experiencing region-wide permafrost thaw and disappearance, both of which are also occurring at unprecedented rates. Permafrost temperatures in the Taiga Plains have been warming steadily over the last several decades, which has been particularly detrimental across its lower latitudes of the discontinuous permafrost zone where the permafrost is already relatively thin and warm. These factors indicate that permafrost in the southern Taiga Plains may be in a state of disequilibrium with the …

Air Quality: Assessment Of Pollutant Levels And Chemistry In Kitchener, On Using Multisensor Pods, Wisam Mohammed

Theses and Dissertations (Comprehensive)

Air quality is a growing concern amongst governmental bodies worldwide. A large number of scientific studies accumulated over the past 25 years suggest that poor ambient air quality is attributed to adverse health effects, especially in vulnerable communities that exhibit pre-existing conditions. The United Nations Children’s Fund (UNICEF) reported around 600 000 deaths globally in children under the age of 5 as a result of acute lower respiratory infections caused by poor air quality. With the current statistics on air quality impacts, it is clear that more needs to be done. This MSc work aims to put into perspective the …

Coastal Landform Change Influences On Endangered Five-Lined Skink Distribution At Northwest Beach, Point Pelee National Park, Canada, Evan Fortushniok

Theses and Dissertations (Comprehensive)

As park visitation increased to Point Pelee National Park up until its peak in 1963, the installation of infrastructure for the purpose of supporting the recreational interest grew with it. At Northwest Beach, large parking lots were built into the coastal landscape and by the 1970s large areas of sand dunes continued to be heavily impacted by the installation of visitor associated infrastructure. The infrastructure resulted in the stabilization of sand on the beach side of the parking lot, resulting in an artificially stabilized and heavily vegetated dune. Over the last few decades, the park slowly reduced the size and …

Lake Huron Shoreline Analysis, Shubham Satish Nandanwar

Theses and Dissertations (Comprehensive)

Lake Huron is a popular tourist destination and is home to several businesses and residents. Since the shoreline is dynamic and is subject to change over the years due to several factors such as a change in water level, soil type, human encroachment, etc., these locations tend to encounter floods due to increased water levels and wind speed. This causes erosion and loss to the properties along the shoreline.

This study is based on two areas of interest named Pinery Provincial Park and Sauble Beach which are located on the shoreline of Lake Huron where Pinery Provincial Park is a …

Exploring Visitor Perceptions And Behaviours Related To Ticks And Lyme Disease Risk In An Ontario Protected Area, Ryan Brady

Theses and Dissertations (Comprehensive)

Lyme disease is the most common vector-borne zoonosis in North America and over the past decade, reported cases of the disease have been rapidly increasing in many regions throughout Canada. The relative novelty of this public health threat presents nature-based tourism and recreation organizations with a range of policy and management challenges. Currently, there is a limited understanding of public perceptions and behaviours associated with tick and Lyme disease risk, especially within a Canadian parks and protected areas visitation and visitor experience context. To address this practical and scholarly knowledge gap, this study utilized in-situ surveys to explore visitor perceptions, …

Change Detection And Landscape Similarity Comparison Using Computer Vision Methods, Karim Malik Wilfrid Laurier University

Theses and Dissertations (Comprehensive)

Human-induced disturbances of terrestrial and aquatic ecosystems continue at alarming rates. With the advent of both raw sensor and analysis-ready datasets, the need to monitor ecosystem disturbances is now more imperative than ever; yet the task is becoming increasingly complex with increasing sources and varieties of earth observation data. In this research, computer vision methods and tools are interrogated to understand their capability for comparing spatial patterns. A critical survey of literature provides evidence that computer vision methods are relatively robust to scale and highlights issues involved in parameterization of computer vision models for characterizing significant pattern information in a …

Fetishized Nature Or Life-Giving Breath? Religion As Skill In Climate Change, Sigurd Bergmann

Consensus

Anthropogenic climate change and unsustainable modes of production, consumption and lifestyles represent one of the most demanding challenges facing Earth, our home and humanity. Therefore religious belief, faith communities and spiritual commitment are highly needed to prepare the ground for what has been described as the necessary “great transformation”. To achieve this transformation, we need a new climate narrative and iconography, supported by a broad alliance of local and trans-local social forces. Religion has a significant role to play in this mobilization. This article begins by depicting several reasons that religion is a crucial driving force in the needed great …

Ecology And Christian Education: How Sustainability Discourse And Theological Anthropology Inform Teaching Methods, Chad Rimmer

Consensus

This paper will sketch theoretical synergies between sustainability discourse and a Christian ecotheological approach to religious education, and point to pedagogical possibilities for bridging the two disciplines. Theology and natural science operate with certain anthropological assumptions. Those underlying anthropologies inform the teaching methods of environmental and religious education. Anthropologies that conceive of human being outside of ecological relationships are a root problem of our current ecological crisis. Many economic, political and social discourses colonize people from the land, particularly children, exacerbating the root causes of sustainability. This paper affirms that linking sustainability discourse and religious education is a way to …

Women, Climate Change And Eco-Theology, Mary (Joy) Philip

Consensus

The impact of climate change is not proportionate to the ones that contribute to it. It is the world’s poorest and those in vulnerable situations, especially women and children, who bear the brunt of environmental, economic and social shocks. This paper highlights the fact that women are disproportionately affected by climate change, when they are primarily the ones that have been caring for and preserving the earth. This paper also argues for the need for eco-consciousness and the increased participation of women in climate initiatives, as women have a theology and spirituality undergirded by eco-consciousness.

Sustainability And Climate In Religion: A Case Of Study Of The Green Churches Network In Africa (Toile Des Églises Vertes En Afrique) Teva, Marcel Ngirinshuti

Consensus

Faced with the ecological crisis, many churches are involved in the search for concrete solutions. Since 2016, the Green Churches Network in Africa (TEVA), a network of churches, denominational structures and associations, which are committed to caring for the "common home" (planet-earth) in Africa. This organization currently has (as of 2019) 1,808 parishes grouped into 19 churches in 12 African countries. The vision of TEVA is to reach 2020 green parishes by the end of 2020. Starting with the fact that ecological questions are often perceived as utopian and very complex, TEVA aims to promote knowledge of African ecological issues …

Introducing A Comparative Ecotheology: Islamic Concept Of Basmalah And Luther’S Commentary On The Ten Commandments, Sayed Hassan Akhlaq

Consensus

In our trying time of the COVID-19 pandemic, this paper discusses current environmental concerns in light of critical questions about the relationship between God and Mother Earth. This paper addresses this question in an inter-religious context. In order to fulfil its original duty of inculcating spirituality, faith can build a bridge between God and people on a constructive understanding of the Earth. To this end, Christianity and Islam offer notions of divine grace and divine lutf to do this duty. In this paper, I examine two inspiring sources: the Islamic motto of Basmalah, and Luther’s commentary on the Ten Commandments …

Religious Environmental Stewardship, The Sabbath And Sustainable Futures In Africa: Implications For Sustainability Discourse, Ben-Willie Kwaku Golo

Consensus

In terms of goals and approaches, the potentials of religion and faith communities have had a prolonged marginalisation from the rather intense academic and political engagements in the suitability discourse with a consensus on the concept of sustainability as both an approach and a goal. In this paper, I argue that the highly religious African context would require a religiously inspired and phrased recourse towards a comprehensive sustainability, rather than a solely secular concept of environmental sustainability. This is much more so when environmental sustainability is largely a secular vision of a religious one – environmental stewardship. Ignoring the beliefs, …

Adam, Dust Of The Earth: A Paradise Received And Incomplete In The Biblical Accounts Of Creation. Some Philological Observations On The Creation Accounts, Jean Koulagna

Consensus

In Christian thinking about climate and environment issues, Dogmatic theology has often seemed to precede the exegesis of biblical texts. And when it is suggested, this exegesis is usually based on previously formulated theological conclusions. In other words, exegesis is there to support ethical stands that are no doubt laudable, but have been already established. Under these conditions, it becomes difficult to analyze those texts as they are and to understand them within the historical and anthropological contexts in which they were produced. This article attempts to break this trend by suggesting philological observations concerning the creation accounts in Genesis. …

When Environmental Obligations Collide With State Sovereignty: An International And Sharia Law Perspective, Seyed Masoud Noori, Soheila Ebrahimi Louyeh

Consensus

This article critically reviews the notion of State sovereignty under international law and argues that to achieve eco-justice as well as sustainable development goals, a restrictive and ecological approach needs to be taken toward the principle of states’ permanent sovereignty over natural resources. Environmental sustainability requires states’ environmental obligations to be identified as erga omnes so they can be addressed toward the international community as a whole and fall within the scope of article 48 of the ILC Articles on States Responsibility. Interestingly, in complete alignment with this progressive interpretation, sustainable utilization of natural resources has a longstanding foundation in …

Towards A Green Diapraxis: Experiences And Reflections From An Interfaith Journey, Einar Tjelle

Consensus

The article explores the increased cooperation and dynamic learning between religions during the last decades, on the themes of climate, environment and sustanability. Examples are given from a Norwegian interfaith context, but with global links as well. This cooperation has broadened the scope and perspectives of churches and religions. Contextual and holistic approaches have emerged as fruits of this mutual learning and exchange, the author claims. Pope Francis` encyclical Laudato Si` has captured important parts of this development with its strong message of interconnectedness and moral responsibility. It has also stimulated a wider religious and interfaith global commitment to Mother …

From Environmental Activism To Environmental Education A Historical Overview, Evaluations And A Suggestion For A Path Forward For The Religious Institutions As Partners For A Global Green Shift, Tom Sverre Tomren

Consensus

In this article, the author shows how all the major world religions have engaged in climate and environmental activism by developing theology and practical projects for more than fifty years. Using metadata from the European Social Survey, he shows that members of all religious traditions in Europe have become increasingly positive to the environment and nature. Especially noticeable is the increased engagement of Protestant Christians. Tomren uses a case study from the Lutheran Church in Norway to show how religious actors have a great influence on their own members. Against this background, the author argues that religious institutions should see …

Rockhounding, Seafaring, And Other Material Tales For The End Of The World, Noemie Fortin

The Goose

In the face of accelerated environmental degradation and climate instability, the future of the Earth and of all life on earth is difficult to visualize. Therefore, the different mediums through which we consider environmental issues are just as important as the actions we take to address them. Focusing on three projects combining art, science, and activism, this article suggests a compilation of material tales. They tell stories of plastic rocks and aluminum nuggets where the protagonists are partly finely crafted objects, partly waste materials, and sometimes both at once. Artists Kelly Jazvac, Yesenia Thibeault-Picazo, and the collective Studio Swine collaborate …
