Panel Discussion: Multidisciplinary perspectives on Kalaallit Nunaat<\/strong>\/Greenland<\/h4>\n\n\n\n<\/figure>\n\n\n\n
Panelists: Louisa Bradtmiller, Mary Heskel, Marianne Milligan, Mindy Jewell Price and Tom Robertson<\/p>\n\n\n\n
Greenland has been in the news lately for both its geopolitical importance, as well as its importance to the climate system under climate change. Greenland also has a unique governance structure, and a thriving Indigenous population and culture that has taken an increasing role in self-governance. This panel discussion will feature brief prepared remarks by the four panelists, and then we will welcome discussion and questions from panelists and the audience. Please join us as we test out a new format option for EnviroThursday! <\/p>\n\n\n\n

“Man-Made Jungles: How Indigenous People Made Nepal\u2019s Famous Grassland National Parks<\/strong>“<\/h4>\n\n\n\n
Speaker: Prof. Tom Robertson, Environmental Studies, Macalester Colleg<\/strong>e<\/p>\n\n\n\n<\/figure>\n\n\n\n
Few places offer a better view onto the contradictions of the post-WWII wave of “fortress conservation” than Nepal\u2019s Chitwan National Park. Often called Asia\u2019s Serengeti, Chitwan is home to endangered one-horned rhinos and Bengal tigers, both of which thrive in the park\u2019s tall grasslands (which resemble some Midwest grasslands in some ways). Chitwan is also home to the Indigenous Tharu, who helped maintain the health of the grasslands for generations through yearly burning. In 1973, when international and Nepali conservationists joined forces with the Nepali monarchy to create the park, mostly to protect the grasslands and the charismatic animals who depended upon them, the Nepali army put an end to grazing and burning. The result: a lose-lose situation. Tharu livelihoods suffered, as did the grasslands. 50 years later, only half still exist. <\/p>\n\n\n\n

Learn About the New Geothermal System on Campus<\/h4>\n\n\n\n<\/figure>\n\n\n\n
Speakers: Bryant Johnson, Midwest Mechanical Solutions and Robert Ed<\/strong>, Darcy Solutions<\/strong><\/p>\n\n\n\n
Geothermal is coming to Macalester College, and we\u2019re excited to share what makes this project unique. Unlike traditional ground-loop systems, the Darcy Solutions system\u2014developed right here in Minnesota\u2014places a sealed heat exchanger directly within the aquifer. This approach allows the campus to leverage the stable temperature of groundwater without extracting or consuming it, improving efficiency while minimizing environmental impact. During our presentation, we\u2019ll explain how the system works, why it\u2019s different from conventional geothermal, and what it means for long-term campus sustainability and energy performance.<\/p>\n\n\n\n
March 6, 2026 – Special EnviroFriday<\/h3>\n\n\n\n
Indigenous Issues in Nepal: The Politics of the Environment in the Central Himalaya<\/strong><\/h4>\n\n\n\n<\/figure>\n\n\n\n
Speaker: Dr. Dhirendra Nalbo<\/strong><\/p>\n\n\n\n
The size of Tennessee, Nepal has over 100 languages and 30 million people, many of whom belong to historically marginalized Indigenous groups. <\/p>\n\n\n\n
In this talk, Dr. Nalbo will examine the complex intersections of state-led development, environmental governance, and Indigenous rights. He will examine “fortress” conservation in Nepal’s densely populated lowlands, including in Koshi Tappu Wildlife Reserve in southeastern Nepal. He will also discuss the Indigenous Limbu (Yakthung) nation’s resistance to a commercial cable car project on Mukkumlung, a sacred mountain in northeastern Nepal. Dr. Nalbo advocates for a paradigm shift that centers Indigenous methodologies and restorative justice.<\/p>\n\n\n\n
Dr. Dhirendra Nalbo is the Co-Founder of the Open Institute for Social Science, an independent academic cooperative based in Kathmandu, Nepal. His research focuses on peace and conflict studies, Indigenous people and the environment, natural resource governance, and climate change.<\/p>\n\n\n\n

Working Productively Across Differences in Values: Exploring the Siting of Data Centers <\/strong><\/h4>\n\n\n\n<\/figure>\n\n\n\n
Panelists: Prof. Takeo Kuwabara, Julian Hartland, Dylan Jeppe, Lukas Locks-Scamp (’25), Tessa Myatt, Zaki Numani (’24), and Seneca Wilson<\/strong><\/p>\n\n\n\n
Everyday we navigate conflict: from determining who will finally wash those dirty dishes in the sink to exploring how to work with a difficult co-worker on a shared project.<\/p>\n\n\n\n
But if you follow the news today, it can seem like the differences dividing us are increasing and our ability to come to shared understandings is decreasing. In this context, it might feel difficult to engage with disagreements.<\/p>\n\n\n\n
Join us to learn about the science behind a consensus building approach to conflict and practice the skills of leveraging differences to enhance outcomes. We will utilize a participatory experience examining how municipal governments are negotiating the siting of data centers.<\/p>\n\n\n\n
The event is supported by a Project Pericles grant, Macalester Environmental Studies, and the Dialogue Across Differences initiative. The case builds upon ongoing research on the environmental and social impacts of data centers being conducted at the University of Minnesota.<\/p>\n\n\n\n

Speakers: Zaryn Prussia ’23, Fern Naomi Renville, Roger Fernandes, Dr. Mary Heskel, Dr. Susan Green <\/strong><\/p>\n\n\n\n
We\u2019ve been collecting maple sap from trees on campus. Join us as we boil the sap down into syrup. Making syrup takes hours, so we\u2019ll be out in the Webers Rock Garden all day. We\u2019ll have a few guests join us for some storytelling.<\/p>\n\n\n\n

“An Integrated Above and Belowground Perspective of Carbon and Nutrient Cycling in Terrestrial Ecosystems: Insights to Advance Ecosystem Science and Land Management Practices”<\/h4>\n\n\n\n
Speaker: Dr. Adrienne Keller<\/strong><\/p>\n\n\n\n
Much of what we know and how we think about terrestrial ecosystems comes from aboveground observations and measurements. That\u2019s not to ignore the wealth of interest and scienti\ufb01c work focused on belowground properties and processes. However, above- and belowground processes are often considered in isolation. Consider how an integrated above- and belowground perspective of carbon and nutrient cycling can provide new insights to understanding plant-soil-microbial feedbacks. Consider the value of taking such an integrated perspective when managing natural and working lands, particularly in the face of climate change. I will highlight some of my recent work helping land managers think about how to manage their lands for both climate mitigation and climate adaptation goals. This event is hosted by Environmental Studies & Biology.<\/p>\n\n\n\n
Dr. Adrienne Keller is a Visiting Assistant Professor in the Environmental Studies Department. <\/p>\n\n\n\n

“Restoring Ecosystems from the Ground Up: The Importance of Soil Health and Biodiversity for Building Resilience on Tribal Lands”<\/h4>\n\n\n\n
Speaker: Dr. Danielle Ignace<\/strong> Co-Sponsored with Biology, Macalester Native and Indigenous (MNI) Initiative<\/p>\n\n\n\n<\/figure>\n\n\n\n
Projected changes in climate and disturbances will impact nearly every aspect of Indigenous community health, wellbeing, and lifeways. These outcomes increase the importance of understanding (1) how ecosystems may function as carbon sinks or sources in coming decades, and (2) how Indigenous communities are affected by these ecological impacts. The Coeur d\u2019Alene Tribe has long had a goal of restoring the prairie area around the Hangman watershed (northern Idaho), and more recently, seeks to regenerate healthy forests. I present how the Coeur d\u2019Alene Tribe is meeting this challenge by implementing nature-based climate solutions on the reservation. The Tribe\u2019s goal focuses on how to manage its lands to ensure that key culturally and ecologically significant species are protected, while also restoring Tribal first foods. This event is hosted by Environmental Studies & Biology. <\/p>\n\n\n\n
Dr. Danielle Ignace is an Indigenous (Coeur d\u2019Alene Tribe) Associate Professor in the Department of Forest Resources at the University of Minnesota and a Research Associate at Harvard Forest studying the impacts of climate change, fire, and introduced species on ecosystem health and Indigenous communities. She serves as the Chair of the Traditional Ecological Knowledge Section of the Ecological Society of America and is the chapter lead for the Drivers of Change of Nature chapter of the first-ever assessment of nature in the U.S (The Nature Record). Dr. Ignace is passionate about mentoring the next generation of scientists in transdisciplinary work while centering the values of communities most impacted by global change. <\/p>\n\n\n\n

\u201cThe Nuclear Past and the Nuclear Future”<\/strong><\/h4>\n\n\n\n<\/figure>\n\n\n\n
Speaker: Prof Jim Feldman, UW Madison<\/strong><\/p>\n\n\n\n
Nuclear energy plays a central role in American society\u2014but in ways that we often cannot see. After World War II, the U.S. built a powerful consumer society predicated on using nuclear energy to both fight communism and power the economy. In doing so, Americans embraced a set of assumptions about progress, citizenship, and the human relationships to nature that remain central to American life, even as our direct engagement with nuclear energy seems to have disappeared. We are still living in Nuclear America, and the nuclear past poses questions still relevant for the nuclear future. <\/p>\n\n\n\n
Environmental Studies Honors Presentations<\/strong> (listed in order of presentations)<\/h4>\n\n\n\n
“Sustainability Savvy: The Role of Competence and Efficacy in Promoting Pro-Environmental Behavior” <\/strong>by Lorenna Graham ’26<\/p>\n\n\n\n
Many understand personal pro-environmental behavior (PEB) to be necessary, yet fewer engage in it, prompting a need to investigate psychological factors responsible. The present research investigates the influence of cognitive dissonance, outcome efficacy, and self-efficacy on PEB. Study 1 investigates the relationship between cognitive dissonance and PEB with outcome efficacy and competence as potential moderators. In Study 2 we further examine competence and outcome efficacy, adding a self-efficacy manipulation dimension. Results indicate strong positive associations between both competence and self-efficacy and PEB, suggesting that feeling capable of behaving sustainably is significantly related to individuals\u2019 intention to do so.<\/p>\n\n\n\n
“Red Lines, Green Blooms: Assessing the Effects of Historical Environmental Disparity on Algal Communities in the Twin Cities, MN\u201d <\/strong>by Georgia Akins ’26<\/p>\n\n\n\n
Redlining, a race-based housing discrimination practice institutionalized in the 1930s through the Home Owners\u2019 Loan Corporation (HOLC), systematically restricted investment in predominantly non-white neighbourhoods and contributed to enduring patterns of urban inequality. Although outlawed in 1968, its legacy continues to shape disparities in environmental conditions across U.S. cities. While these effects are well documented in terrestrial systems, far less is known about how redlining influences freshwater ecosystems. This study investigates relationships between historical redlining and urban water quality in the Twin Cities metropolitan area (Minneapolis and Saint Paul, Minnesota) using algal community composition as a biological indicator. Across 28 water bodies sampled during the summers of 2022 and 2024, physical and chemical parameters\u2014including surface water temperature, soluble reactive phosphorus (SRP), and chlorophyll-\u03b1\u2014were analyzed alongside morphological and molecular assessments of algal communities. These data were compared across HOLC grades to evaluate potential ecological legacies of historical disinvestment. Results reveal limited and inconsistent relationships between HOLC grade and most water quality and biological metrics. Surface water temperature showed a significant association with HOLC grade, with higher temperatures observed in A and B-graded neighbourhoods compared to C and D-graded areas. In contrast, SRP and chlorophyll-\u03b1 concentrations exhibited no significant relationship with redlining classifications. Algal community composition was dominated by cyanobacteria across all sites, but neither relative biovolume nor overall diversity varied significantly with HOLC grade. Instead, algal diversity showed a stronger relationship with nutrient concentrations than with historical redlining patterns. These findings suggest that contemporary environmental conditions, rather than historical redlining alone, may play a more direct role in shaping urban freshwater ecosystems. By highlighting the complexity of socioecological interactions in aquatic systems, this study contributes to a growing body of environmental justice research and underscores the need for multifaceted approaches to understanding and managing urban water quality.<\/p>\n\n\n\n
“Urban Water Bodies & Redlining in the Twin Cities: A Study of the Water Cooling Effect Across Neighborhoods” <\/strong>by Lucia Zuvela ’26<\/p>\n\n\n\n
Urban heat exposure is unevenly distributed across U.S. cities, reflecting legacies of discriminatory housing policies. From the 1930s to 1960s, redlining maps graded neighborhoods from \u201cA\u201d (best) to \u201cD\u201d (hazardous), with \u201cD\u201d areas characterized by poorer environmental conditions and communities of color. Although banned in 1968, these patterns are argued to persist. While green infrastructure has been widely studied in this context, this thesis examines whether cooling from urban water bodies varies across historically graded neighborhoods in the Twin Cities, Minnesota. Using Landsat imagery and field measurements, results show stronger cooling in \u201cA\u201d-graded neighborhoods, highlighting enduring environmental inequalities.<\/p>\n\n\n\n
“Fossil Fuels in a Decarbonized Country? Modeling the Drivers of Icelandic Oil Sales” <\/strong>by Inbal Armony ’26<\/p>\n\n\n\n
Although 100% of Iceland\u2019s electricity comes from renewable energy sources, it still relies on fossil fuels for land transportation, marine transportation, aviation, and some industry. Understanding geographic nuances in oil use is critical to achieving Iceland\u2019s goals of carbon neutrality by 2040. As the island has one primary urban center with two thirds of the population, information is lacking about oil use in non-Capital areas and a gap between state and municipal climate plans. Using newly available data of oil sales at the municipality-level in a Small Area Estimation model, I analyze drivers of oil sales across Icelandic municipalities. I find municipal income and the use category of the oil sale to be significant predictors of high oil sales. High unstructured spatial variability in the model suggests that local climate action plans are necessary to address municipality-specific energy needs and transition barriers. As other countries focus their efforts on renewable electricity grids, Iceland presents useful lessons about persistent barriers to decarbonizing the land and marine transportation sectors. <\/p>\n\n\n\n
