The land-sea interface area (LSI) faces rising pressures, including increased pollution and biodiversity loss, carbon cycle dynamics, and climate change threats. Diverse efforts are currently being made to observe those crucial areas of the world, including through in-situ and satellite observations, modelling, and citizen science activities. But to fully unlock the potential of these efforts to understand and protect the land-sea interface area from these challenges, further cooperation is needed.

Brought to you by LandSeaLot, the Land-Sea 2026 conference assessed the progress that has been made so far to improve observations and invited scientists, decision makers, and regional stakeholders to contribute to a robust Common Observation Strategy for the future of the LSI. With sessions that introduced LandSeaLot’s mission, explored novel methods such as the use of cost-effective observation technology, and shared success stories emerging from regional and local actions and citizen science collaborations, Land-Sea 2026 showcased achievements to date and gave the opportunity for input to the  Common Observation Strategy for understanding and addressing challenges at the LSI.
