University of Vermont Celebrates its First World Water Day, co-sponsored by Lake Champlain Sea Grant
On Friday, March 21, the University of Vermont’s first-ever World Water Day celebration was hosted by Lake Champlain Sea Grant, the UVM Water Resources Institute, and the Vermont Water Resources and Lake Studies Center. Recognized around the globe, World Water Day is an annual United Nations Observance that raises awareness about the importance of freshwater and the need to protect this vital resource. Since 1993, this observance aims to tackle the global water crisis and raise awareness of the 2.2 billion people living without access to safe water.
This year’s theme, designated by the United Nations the role of glaciers in maintaining global freshwater supplies. While glaciers aren’t found in the Lake Champlain Basin, the event used the opportunity to share a more local concern: warming winters in the Northeast.
Dr. Alix Contosta, an ecosystem ecologist from the University of New Hampshire, spoke to an engaged audience of around 50 people, and explained what exactly scientists mean when they reference “warming winters”. Contosta’s talk focused on the vernal window—the short period between when snow has melted but before trees have fully leafed out. This window is important for many understory plants, which take advantage of full sunlight to begin growing before the forest canopy returns.
Despite the sunny afternoon, Contosta reminded the audience that snow passed through the Champlain Valley just the night before but melted with the strong spring sunshine—a familiar sign of the shifting seasons and an indicator that we were in the vernal window. Dr. Contosta’s research shows that this window is lengthening as the region experiences warmer, less snowy winters. These changes may significantly impact plant growth patterns, forest dynamics, and broader ecological processes like water flow, carbon uptake, and nutrient cycling.
After the keynote, attendees enjoyed a lively Q&A session, followed by networking and tabling with regional partners. Representatives from the Rubenstein Laboratory, Northern Woodlands Magazine, Adirondack Watershed Institute, Vermont Rural Water, Lake Champlain Committee, and the UVM Spatial Analysis Lab were on hand to share how their work supports clean water and healthy ecosystems across the Lake Champlain Basin and beyond.
“As an inaugural World Water Day celebration, this event did a great job of connecting global issues to our local context. Our speaker and partners really engaged the audience and showcased the myriad connections between water, the environment, and local communities. Overall, this event was a great way to start a new tradition at UVM,” said Anne Jefferson, Lake Champlain Sea Grant director.
