  • CRC Spotlight: Brock researcher examining ways to foster water resilience


    The federal government’s 
    Canada Research Chairs program invests up to $311 million per year to attract and retain some of the world’s most accomplished and promising minds. Chairholders are recognized to be national and international experts in the fields of engineering and the natural sciences, health sciences, humanities and social sciences. Brock University has 10 active Canada Research Chairs, with more to be announced. This monthly series profiles the work, and lives, of Brock’s Chairholders.

    When she wants to take a break in her busy schedule, Julia Baird heads out to a lake or river.

    “I’ve always found water to be a source of calm in my life,” says the Associate Professor in Brock’s Environmental Sustainability Research Centre (ESRC) and the Department of Geography and Tourism.

    “Water is critical to life; it’s inherent in us that we’re connected to water,” she says. “I think of the well-being of future generations and how important it is to support sustainability.”

    As Tier 2 Canada Research Chair in Human Dimensions of Water Resources and Water Resilience, Baird investigates activities that have an impact on water. She studies how decisions regarding water use are made at the government, community and individual levels through her Water Resilience Lab.

    “The diversity of voices, and how those voices are included and connected, is critical for creating the right conditions for water sustainability,” she says.

    Central to her work is the concept of water resilience, which Baird says involves “being able to continue to support the well-being of the system despite whatever disturbances may arise.”

    Baird says there are three ways to respond to disturbances in the environment, such as floods or droughts brought about by climate change: persist where possible in spite of disturbances, adapt to situation or transform the way society operates to mitigate or avoid disastrous impacts.

    Ideally, decision-making processes related to water, as well as related areas such as land-use planning, agricultural operations, coastline protection and erosion control, are guided by water resilience principles and practices.

    Baird has long been fascinated by how people make decisions and how individuals influence decisions carried out at the political level. Her research looks at how psychological traits, such as empathy and self-efficacy at the individual level, can motivate the public to support decisions that lead to water sustainability.

    Empathy is associated with attitudes that reflect stronger support for resilience-based approaches for the environment.

    In a study led by Baird, participants in six countries who read three scenarios describing situations of flooding, drought and depleted fish stocks gave moderate to strong support for governance taking a resilience-based approach.

    “We know that empathy is malleable, it can change in people,” says Baird. “The question is, how can we build empathy broadly so that the public will influence changes that can have positive impacts down the line?”

    Baird earned her PhD in Environment and Sustainability from the University of Saskatchewan in 2012 and came to Brock as a post-doctoral fellow. She became Associate Professor in the ESRC and the Department of Geography and Tourism Studies in 2021.

    In that same year, Baird was granted her Canada Research Chair position, which was renewed in 2022.

    Baird has had a number of accomplishments during her terms, including:

    In her second term, Baird plans to test interventions to build empathy broadly in society and examine the long-term impacts of empathy interventions on behaviour.

    “Ultimately, our work is centered on finding solutions to some of today’s most pressing water issues,” says Baird. “I’m motivated by that every day.”

  • New research finds evidence of climate-driven changes to northern lakes

    Across the Old Crow Flats in the northern Yukon, lakes are telling a story of climate-driven change.

    The traditional territory of the Vuntut Gwitchin First Nation (VGFN), the Old Crow Flats is recognized as a Ramsar Wetland of International Importance thanks to its more than 8,000 thermokarst lakes (up to 15 square kilometres) and ponds. Thermokarst lakes are formed by thawed permafrost and can be prone to drainage if they expand into low-lying areas.

    Kevin Turner, an Associate Professor in Brock’s Department of Geography and Tourism Studies and Fulbright Canada Research Chair in Arctic Studies at the University of Washington, has studied the area since 2007, and he says that warmer temperatures, longer summers and more rain are “priming this important landscape for continued climate-driven landscape change.”

    In a new paper with Lauren A. MacDonald, who was a post-doctoral research fellow at Brock in fall 2020, as well as researchers from Wilfrid Laurier University, University of Waterloo and Parks Canada, Turner and his team share an analysis of water samples suggesting significant trends toward increased rainfall in the area, which could affect drainage in the shallow lakes and cause changes to soil stability along shorelines.

    The research, conducted under the direction of the Vuntut Gwitchin Government and the North Yukon Renewable Resources Council, saw sampling take place from 14 lakes in the Old Crow Flats two to three times per year from 2007 to 2019.

    The samples produced a 13-year record that the research team has analyzed using water isotope tracers to distinguish between input sources, such as rainfall and snow melt, and also to track water losses due to evaporation.

    “There is more than meets the eye with these results, as they represent a status indicator of the increasing vulnerability of this area to drastic change,” says Turner. “For example, permafrost, which holds the landscape intact, degrades more during warmer and wetter conditions, which can lead to more shoreline slumping and rapid drainage of lakes into the river network.”

    These changes to the landscape can disrupt ecosystems, affecting plants and wildlife and interfering with traditional ways of life — a trend already recognized by the VGFN.

    “Findings complement the traditional knowledge of the VGFN, who have observed changes in climate and landscape characteristics during recent decades and have recently declared a climate emergency,” says Turner.

    Isotopic evidence of increasing water abundance and lake hydrological change in Old Crow Flats, Yukon, Canada” was published in Environmental Research Letters in late November. Turner says that its findings demonstrate why collaboration and co-operation in research is so important.

    “This research showcases the value of innovative and collaborative long-term monitoring programs in these important and remote areas of the North where the impacts of climate change are heightened,” he says.

  • Five Brock courses with a focus on climate change

    As the COP26 climate summit continues with world leaders talking climate change in Glasgow, Scotland, the topic is also at the forefront of both research and courses at Brock University. Climate change and its effects is discussed in various Faculties and from a variety of angles at Brock. Here are five examples of how students are learning about climate change.

    Contemporary Environmental Issues

    ENSU 3P90 is an Environmental Sustainability capstone course for Brock students who share an interest in sustainability and a concern for improving the relationships between people and the planet. Students engage in a wide range of sustainability issues, including climate change and biodiversity loss as well as displacement and environmental racism.

    The course’s instructor, Jessica Blythe, Assistant Professor in Brock’s Environmental Sustainability Research Centre, says it resonates with students who are seeking to make a positive change in the world.

    “Many members of Gen Z feel overwhelmed by the state of the world and are responding by devoting their professional careers to finding solutions,” she said. “This course is designed to help students develop core competencies in sustainability science, including systems thinking, anticipatory and strategic skills, so they can thrive in sustainability careers and contribute to addressing the climate crisis.”

    Watershed Study and Assessment

    ERSC 4P31 is an Earth Sciences course that looks at the environmental health of two branches of the upper Twelve Mile Creek. Students in the course measure water quality parameters under different ambient conditions. They then get to compare their results with historical ones obtained in 1978 and 2001.

    Professor of Earth Sciences and course instructor Uwe Brand said the exercise encourages participants to re-evaluate their perceptions of clean water and its availability.

    “The course should show them that water is not only important to the fauna of the creek but also speaks to our water security,” he said. “In light of increasing CO2 emissions and global warming, don’t take anything for granted, including access to ‘clean’ water.”

    Environmental Economics

    ECON/TOUR 2P28 is a course that provides Economic perspectives on environmental and natural resource issues. Economics Instructor Geoff Black, who leads the course, said it is often an eye-opening experience for students.

    “We look at ways in which this shortcoming can be modelled and investigate policy that can bridge the gap,” he said. “It’s important for students to understand the market failures that occur regarding both common resources and public goods.”

    Ecocinema: History, Theory, Practices

    COMM/FILM/PCUL 4P58 is a Film Studies course that explores the proliferation of both fiction and nonfiction films that deal with the climate change, species extinction, resource extraction and other industrial practices.

    Course instructor Christie Milliken, Associate Professor of Film Studies, said the topic of climate change has been more prevalent in recent years, but it was also common in science fiction films in earlier decades.

    “The course invites students to consider the various rhetorical strategies deployed across a range of films as they invite us to rethink our relationship to the planet,” she said.

    Climate Crisis

    GEOG/ERSC 2P08 is a Geography course that provides an Introduction to the Earth’s atmosphere and the natural and anthropogenic drivers that change the Earth’s climate system. These include the Greenhouse effect, human activities that alter the climate system, climate models, climates of the past and projections of future climate.

  • Brock students find alarming amounts of plastic in sand at St. Catharines beach

    A day at the beach doesn’t often involve lab work, but for a group of Brock University fourth-year Geography students tasked with assessing plastic waste on the shores of Lake Ontario last fall, it was just that.

    Back in October, students from Professor of Geography and Tourism Studies Michael Pisaric’s GEOG 4P26 class visited Sunset Beach in north St. Catharines to measure the quantity of plastics turning up in the sand.

    Students measured out plots on the beach and sifted through the sand to collect as many tiny pieces of plastic as they could. They compiled their findings in lab reports for the end of the Fall Term.

    The results are now in, and they’re alarming.

    In one sample alone, one square metre of the beach yielded 665 individual pieces of plastic material.

    Pisaric called the amount and variety of plastics collected in the samples “striking.”

    “I think much of the discussion concerning plastics in the environment has been focused on the oceans and we are quickly understanding that plastic pollution is also an important issue closer to home in the Great Lakes,” said Pisaric, who is also Chair of the Geography and Tourism Studies Department. “This small study of a single beach on Lake Ontario clearly shows the prevalence of plastic pollution in our own backyard is a serious problem.”

    Emily Bowyer, a third-year student from Mississauga majoring in Geography and Biology who participated in the field collection, described it as “an opportunity to see the magnitude of the problems in the environment first-hand.”

    Another surprise to the team was the prevalence of nurdles — small plastic pellets used in the manufacture of many different goods.

    Investigation during the course uncovered a 2013 Toronto Star article that suggested nurdles may have made their way into Lake Ontario via the Humber River during a factory fire.

    “It is interesting to speculate that the prevalence of nurdles we noted in our samples may have originated on the other side of Lake Ontario,” Pisaric said.

    The professor plans to run a similar investigation when the course is offered again next fall to address some of the questions that cropped up in light of the results of the students’ labs.

    “Perhaps next time around I will have the students compare the beaches on Lake Ontario with a beach on Lake Erie,” he said. “Are similar quantities of plastics occurring in both areas? Do the types of plastic differ between the two lake environments?”

    Carolyn Finlayson, Experiential Education Co-ordinator for the Faculty of Social Sciences, attended the field trip and witnessed how interested casual beach visitors were in the students’ activities.

    “It’s a wonderful example of the larger impact experiential learning can have on our Niagara community and our students,” she said. “By working at the beach that day for their lab, students were able to start conversations with beachgoers about their use of plastic and its impact on the shorelines they enjoy.”

    Cara Krezek, Director of Co-op, Career and Experiential Education, said these were exactly the types of courses the University envisioned when it committed to expanding experiential learning so all students had access to meaningful experiences in their programs.

    “Courses like these take our students into a real-world setting and allow them to apply their knowledge, learn new skills and reflect on how they can take these experiences forward to a future career path,” Krezek said. “I am certain these students will never forget their findings and it will change the way they interact with plastics.”

    Emily Bowyer, Pravin Rajayagam and Dakota Schnierle, students in a fourth-year Geography course at Brock, sift through sand on Sunset Beach in St. Catharines to find out how many plastics are washing up on the beach.

    Other Media Coverage

    Brock students find alarming amounts of plastic at St. Catharines beach: Extensive media coverage was given to an experiential learning exercise led by Professor of Geography and Tourism Studies Michael Pisaric that saw Brock students uncover more than 2,000 pieces of plastic on St. Catharines’ Sunset Beach. The story was featured in the St. Catharines Standard, CBC, CHCH, Newstalk 610 CKTB and Coastal News Today.

  • Film crew joins Crawford Lake research efforts

    When a group of researchers returned to Crawford Lake to continue the search for evidence of a possible new geological era, they came with a film crew to document the occasion.

    Toronto-based Mercury Films joined the team of scientists, led by Brock’s Department of Earth Sciences, shooting footage during last month’s trip to the Milton site to collect samples.

    The team is studying the lake as a possible location to define a new geologic epoch called the Anthropocene. It is one of 10 sites being captured by Mercury Films.

    The production company’s most recent film,Anthropocene: The Human Epoch, premiered at the Toronto International Film Festival this past September and is part of a multimedia project that includes a major travelling museum exhibition of photographs, short films and augmented reality. It has been featured at the Art Gallery of Ontario and National Gallery of Canada, and will be on display in Bologna, Italy, in April.

    In addition to the field work, Mercury Films will visit Brock to obtain footage of the laboratory analysis component of this research effort. As part of a project, contracted through the German government, they will highlight each site’s candidacy for type section — a location where evidence of a time period shift can be seen — and cover all the steps leading to the formal proposal of the Anthropocene epoch.

    In order to receive this ‘golden spike’ designation, a proposal must be submitted to the Anthropocene Working Group (AWG) for evaluation. If the AWG approves of this proposal, it will then be evaluated by the International Subcommission on Quaternary Stratigraphy, chaired by Brock University Professor of Earth Sciences Martin Head.

    While the world is technically in the Holocene epoch, the group researching Crawford Lake, which also includes researchers from Carleton and McMaster universities as well as Conservation Halton, hopes their findings can convince fellow scientists around the globe to establish the start of the latest geological age.

    Researchers suggest the Anthropocene began around 1950. While it hasn’t been officially adopted as a geological epoch, Brock Professor of Earth Sciences Francine McCarthy and her team are attempting to build a case for Crawford Lake.

    To get a better understanding of the history that exists within Crawford, annually laminated sediments called varves are recovered through freeze-coring — a process that involves dropping a dry ice and ethanol filled-metal sampler into the lake.

    “Over the next year or so, various types of analysis of the varves and the overlying water will be conducted, including radionuclide analysis to look for the ‘bomb spike’ and evidence of the Great Acceleration since the Second World War,” McCarthy said. “If a good radionuclide signature, including plutonium, is present in the sediments of Crawford Lake, the site will be a strong contender as the type section, with a ‘golden spike’ at around 1950.”

    Faculty of Math and Science Dean Ejaz Ahmed commended team members for their efforts.

    “I would like to send my congratulations to the team for their work on this matter,” he said. “They should be both proud of their research and excited by the attention it is receiving.”

    There is still plenty of work to be done before the Anthropocene is recognized as a geological era. Progress reports from 10 candidate sites will be presented in April at the upcoming European Geophysical Union Meeting in Vienna. Additionally, supporters from each site will travel to Berlin in May to discuss the next steps that need to be taken to establish the Anthropocene epoch.

  • Professor Noella Gray hosts marine conservation seminar

    REPOSTED FROM THE BROCK PRESS
     | January 29, 2019

    Brock’s Geography and Tourism studies hosted a two-hour long seminar entitled Global Marine Conservation: Science, Policy and Territory. The seminar was hosted by Dr. Noella Gray from the Department of Geography, Environment and Geomatics at Guelph University.

    The seminar held on January 24, 2019, saw Gray expounding on the impact of marine protected areas (MPAs) and the increasing prevalence of ocean nationalism. Gray researches the politics of conservation and environmental governance.

    “I consider how science is incorporated into environmental policy, the politics of scale in marine conservation, and how resource management policies are negotiated under co-management arrangements,” said Gray. “I have studied both ecotourism and [MPAs] as examples of conservation interventions and how they contribute to political ecology, common property and science and technology studies.”

    MPAs refer to areas of the ocean that are legally protected and managed with the intent being to achieve the long-term conservation and sustainable use of aquatic flora and fauna. The total ocean area under protected status has increased almost tenfold since recent times, and a number of global commitments have further encouraged new territories to establish MPAs.

    “The overwhelming response by conservation scientists to the issues that plague the ocean such as dumping of waste and overfishing has been to establish [MPAs],” said Gray.

    The entirety of the seminar was focused on factors that are driving the territorialisation process, and what the consequences of this process are by looking at the increase of very large exclusive economic sea zones in countries and the effort to increase the number of protected areas in areas beyond national jurisdiction — the so-called high seas.

    Gray presented information based on the findings of two of her recent research projects: a long-term collaborative study of international conservation governance, focused on the evolution of high seas conservation; and a multi-site study of five large-scale MPAs. Gray considered the role of science and technology, as well as both state and non-state actors, in producing conservation territories, and highlighted both the possibilities and limits of territorial thinking in the oceans.

    According to the Convention on Biological Diversity, the long-term goal for the protection of the territorial oceans is that by 2020, 10 per cent of coastal and marine areas, especially areas of particular importance for biodiversity and ecosystem services, will be conserved through effectively and equitably managed marine protected areas.

    Gray’s presentation drew on examples of three of the five territories that she studied: Palau, Kiribati and Bermuda. Both Palau and Kiribati have hit their 10 per cent goal prior to 2020 and have large MPAs bursting with aquatic life. Bermuda, on the other hand, does not have any MPAs despite ongoing debates to create one, however, their oceans are still teeming with aquatic life. Through the use of those examples, Dr. Gray highlighted some of the common arguments for and against the establishment of MPAs.

    “We’re at a really striking moment historically in terms of this increase in territorialisation of the ocean space. There’s a lot at stake in all of this line-drawing that’s happening, both for oceans and for the people who depend on them. As we race towards these international targets, I encourage [individuals] not to get lost in the rapid climb to meet an arbitrary target,” said Gray. “Instead, think about what is driving this effort and what the benefits and underlying drawbacks are when we employ certain conservation methods.”

    The seminar hosted was the first of a four-part series put on by the Department of Geography and Tourism Studies. Interested students are encouraged to attend the second presentation to be held on February 7 in MCC405 by Dr. Hasan Karrar on 50 years of Pakistan-China Connectivity Across the Karakoram.

    Students interested in the work that Dr. Gray is doing can connect with her via email at grayn@uoguelph.ca and on social media @NoellaJGray.

  • The meaning of environmental words matters in the age of ‘fake news’

    Reposted from The Conversation | January 10, 2019 5.34pm EST
    Authors: Jessica Blythe, Christine Diagle, and Julia Baird (GEOTOUR, ESRC)

    This week, U.S. President Donald Trump gave a live address on prime-time television where he repeatedly used the words “violent,” “illegal aliens” and “crisis” to arouse public fear. While Trump’s speech was based largely on fallacies, his fear-mongering shapes the national tone and can generate real-world impacts.

    Words matter because they wield power. Words shape our thinking about the world and, in turn, the actions we take. The meaning of words has never been more relevant than now — in the era of “fake news” — when so-called alternative facts abound.

    Environmental words can also be misinterpreted or misused. In the most sinister cases, language can be put to work to promote particular agendas and silence others.

    Remember “beautiful clean coal?” The Trump administration used the term as the backbone for the continued development of the fossil fuel industry. At the same time, it systematically removed the words “climate change” from federal websites, a measure aimed at undermining climate action.

    Power can be expressed through environmental buzzwords. They are used to influence policy direction, funding and produce norms that become entrenched in their meaning around the world. Motivated by this idea, our recent research explores the meaning of three environmental buzzwords — resilience, sustainability and transformation. Meaning influences the way we understand environmental problems and shapes the solutions we prioritize — or don’t.

    The rise of resilience

    Let’s begin with “resilience.” Over the past decade, resilience has increasingly become a rallying cry in the face of climatic change. Resilience has many meanings, from the time it takes to bounce back from a disturbance to more complex interpretations that consider the capacity to persist, adapt or transform in the face of change.

    Evidence shows that individuals, even those who share demographic characteristics or professions, interpret resilience in very different ways. These differences matter and can have implications on real-world actions.

    Flooding of Lake Champlain (seen here) and the Richelieu River in 1991 caused tens of millions of dollars in damage in Vermont, New York and Québec.(AP Photo/Toby Talbot)

    When considering policy and planning related to flooding, for example, understanding resilience as bouncing back can lead to decisions to focus solely on infrastructure investments, while a more complex interpretation may lead to a decision to relocate a vulnerable subdivision away from a floodplain.

    The rise of resilience as a buzzword has also led to its prominence in agendas put forward by organizations looking for funding often without a clear intention or accountability.

    Sustainability for whom?

    The concept of “sustainability” has dominated environmental thinking since the publication of the influential essay “A Blueprint for Survival” in 1972. The notion of sustainability rests upon the idea that we are obligated to future generations and ought to live in a way that preserves natural resources and environments so that our children and grandchildren can enjoy them.

    The underlying idea is that we have the technological and scientific know-how and power to achieve this goal. And this definition of sustainability centres on humans. Asking “what is sustainability and who is it for?” may lead to a surprising shift in this thinking.

    An alternative perspective on sustainability raises new questions: Must we work toward preserving natural environments for ourselves? Is it justified to work toward preserving a species that is harmful to itself and others — like we have been?

    Privileging the well-being of other species over our own — by significantly reducing our use of highly polluting natural resources — may help to slow climate change, for example. This requires, however, a radical shift in our thinking, displacing the human from the centre of our preoccupations.

    Clearly our know-how has not prevented the acceleration of the environmental crisis. Rethinking ourselves as beings that are deeply interconnected with our habitats and those we share it with, as post-humanist thinkers do, could lead to redefining the notion of sustainability and what constitutes an appropriate course of action. Significantly, this new vision of sustainability may not always favour the human…

  • New research by Tourism and Environment alumna published in Ecological Restoration

    New research by Tourism and Environment alumna, Katrina Krievins (’12), was published last month in Ecological Restoration. Read more below.

    Abstract

    Ecological restoration is a means of addressing the ongoing and pervasive degradation of ecological systems. Although the aim of ecological restoration is ecosystem recovery, efforts based on an oversimplified understanding of how complex adaptive systems behave often fail to produce intended outcomes. We explore how advancements made in understanding properties of complex adaptive systems, specifically social-ecological systems, may be incorporated into ecological restoration. We present a conceptual framework informed by tracing the evolution of perspectives in ecological restoration and synthesizing developments in social-ecological resilience. We then employ the framework in the context of freshwater systems to assess Trout Unlimited Canada’s stream rehabilitation training program and evaluate associated restoration initiatives in terms of social-ecological resilience. Findings from this case study indicate that the approach to restoration taught in the training program, along with the initiatives informed by the program, reflect principles for building resilience and were found to be positive. These findings provide encouraging evidence in support of a new approach to restoration informed by social-ecological resilience and initial confirmation of the usefulness of the framework. Valuable insights on the extent to which social-ecological resilience is currently reflected in restoration practices more broadly will come from future research exploring the application of the conceptual framework in a variety of restoration contexts and at a larger scale.
