The Living Planet Symposium 2025 (LPS25), one of the world’s leading events on Earth observation, took place in Vienna from 23 to 27 June. Organised by the European Space Agency (ESA), the symposium once again brought together scientists, policymakers, businesses, and space enthusiasts from across the globe.

Held every three years, the event has continued to grow in scale and influence. With the climate crisis intensifying, this year’s theme focused on “From observation to climate action and sustainability for Earth.”

Over the five days, participants presented and discussed the latest scientific findings and applications of satellite data, reviewing the vital role Earth observation technologies play in addressing environmental and societal challenges. The symposium also showcased innovative missions, products, and services, highlighting how science, policy-making, and the economy can all benefit from insights gained from space.

OBSGESSION was featured through both oral and poster presentations, highlighting the diverse approaches taken by project partners. Key contributions included the use of the Airborne Visible/Infrared Imaging Spectrometer-4 (AVIRIS-4) for monitoring grassland biodiversity and the integration of environmental DNA (eDNA) with high-resolution satellite spectroscopy to map bacterial diversity in Germany’s Bavarian Forest National Park.

Bringing together a diverse community united by a shared interest in Earth observation, the symposium provided a unique opportunity to network and advance collaboration towards climate resilience and sustainability.
