The 2022 RATIC/T-MOSAiC community meeting in Tromsø featured presentations and dialog exploring cross-disciplinary approaches to understanding the impacts of infrastructure and climate change in the Arctic. This half-day hybrid meeting will focus on topics prioritized at past RATIC events: 1) Approaches and recent progress in Arctic infrastructure mapping and monitoring; 2) Arctic community perspectives on infrastructure research and policy needs; and 3) Updates from national and international research initiatives addressing Arctic change, resilience and adaptation in natural, built and social systems.
The meeting was in a hybrid format with options for in-person and online attendance. The meeting is organized by the T-MOSAiC Arctic Infrastructure Action Group as a cross-cutting activity funded by the International Arctic Science Committee. Conveners: Olga Povoroznyuk and Peter Schweitzer (University of Vienna, Austria), Jana Peirce and Skip Walker (University of Alaska Fairbanks, Alaska, USA)

Keynote Presentation: Arctic Community Perspectives
Gunn-Britt Retter, Saami Council, Norway
The Arctic climate has been warming three times faster than the global average the last 50 years. Among other things bringing the winter temperatures to fluctuate around zero for more days during the winter and expanding the growing season at both ends of Summer with several weeks. These are among environmental changes challenging the cultures depending on living resources and nature. Flexibility is among the keys in the toolbox to cope with the climate crises. The society at large need to mitigate climate change and look for alternative energy sources, often sought placed on land already in use by traditional Sámi economies, adding burden to already stressed livelihoods. The supreme court in Norway recently ruled that licences for wind power development on Fosen invalid as the construction violates Sámi reindeer herders' right to enjoy their own culture. The wind turbines were, however, already set up while the complaint was still ongoing and the harm done. The Sámi people is recognized, have its parliaments, organisations, institutions, and consultation agreements and invited to share their views in media and conferences.
The keynote presentation will present the Arctic Indigenous Peoples challenges from a Sámi perspective and raise the question what more is needed to be heard? Why is the society at large still not listening and taking action?
Keynote Presentation: Arctic Infrastructure Mapping and Monitoring
Annett Bartsch, b.geos & Austrian Polar Research Institute
Recent progress in satellite data availability allows for automatised identification of infrastructure in the Arctic. Compared to Landsat with 30 m, Sentinel-1/2 provides with 10 m spatial resolution significant improvement. Roads as well as buildings can be identified. Infrastructure expansion can be monitored by combination with vegetation related observations. Only specific types of infrastructure can be identified, but at sufficient detail to monitor recent expansion consistently across the Arctic. Geographic differences impact on the one hand detection accuracy and on the other hand are reflected in the mapped patterns of human impact.
We derived a first panarctic satellite-based record of expanding infrastructure and anthropogenic impacts along all permafrost affected coasts (100 km buffer) within the H2020 project Nunataryuk based on Sentinel-1/2 satellite imagery. C-band synthetic aperture radar and multi-spectral information is combined through a machine learning framework. Depending on region, we identified up to 50% more information (human presence) than in OpenStreetMap. The combination with satellite records on vegetation change (specifically NDVI from Landsat since 2000) allowed quantification of recent expansion of infrastructure. Most of the expanded human presence occurred in Russia related predominantly to oil/gas industry.
