Large volumes of environmental data are collected today, but much of it remains unused. Now, Arka Ghosh at Umeå University has developed an AI solution that makes complex data from satellite images and weather maps directly usable for decision-makers.

The system, called Ontoraster, links each pixel in images to an intelligent network where data gains clear meaning and can be analysed together with other information. By combining knowledge graphs and AI, users can ask advanced questions and receive fast, comprehensible answers.

"It is an advanced AI solution that could be highly valuable for urban planners as well as crisis and emergency coordinators, says Arka Ghosh," PhD student at Umeå University.

The technology can, for example, identify risk areas during heatwaves or floods and thereby support faster and more accurate decisions. It also enables people without a technical background to use advanced data analysis.

"What previously required extensive manual analysis can now be done in seconds," says Arka Ghosh.

Continuous cover forestry favour hair lichens1.6.2026 08:00:00 CEST | Press Release

Industrial forestry has through clearcutting caused a large-scale decline of hair lichens in Sweden’s forests. Researchers in Umeå University, University of Northern British Columbia, Canada, and Norwegian University of Life Sciences have in a large-scaled field-experiment shown that partial cutting can increase abundance of hair lichens. The study is published in Forest Ecology and Management which publishes original research in forest ecology.

Ice may release more iron than climate models predict26.5.2026 10:00:00 CEST | Press Release

Most people think of ice as frozen and lifeless, but research at Umeå University shows the opposite. A new study published in PNAS demonstrates that ice actively speeds up the breakdown of iron minerals and may release more iron than current environmental models account for. This is crucial for predicting how nutrient cycles, carbon storage, and water quality will change in polar and mountain regions as the planet warms.
