MALIN FALKENMARK, an extraordinary thinker and water scientist, died on 3 December 2023, aged 98. I first met Malin in 1976 when she was the Executive Secretary of the Swedish National Committee for UNESCO’s International Hydrological Decade. She impressed me very much during this first meeting with her razor-sharp analytical ability, objectivity and excellent conceptualization. All her opinions were based on facts and evidence. For nearly the next five decades, our professional lives remained intertwined.
