Hungary and Serbia: when a shared river demands shared solutionsFloods, droughts and pollution are reshaping the behaviour of the Tisza River — the largest tributary of the Danube and a lifeline for communities across five countries.Through the ADAPTisa project, Hungary and Serbia are working together to better understand and anticipate these changes. Researchers, universities, water authorities and citizens are pooling data to build a shared digital platform for integrated river basin management. The goal is simple but ambitious: improve flood and drought forecasting and support faster, better-informed responses.On the ground, this cooperation takes many forms. Volunteers clean riverbanks, researchers collect water samples, and local memories of past floods are recorded — all feeding into models that combine historical data, real-time measurements and AI-based simulations.When climate risks don’t stop at borders, cooperation can’t either — with EU support.
