IWA Thought Leadership

Recognised for their unique and significant long-term contributions to advancing water science and management


Responding to global water challenges, IWA progressive agendas support sustainable urban and basin-related water solutions.

Berlin’s goal is to create a city-wide network of landscaped streets, and linear parks which link the city’s neighborhoods to one another and to the major parks (about 18 %) to ventilate and absorb extreme storm weather (e.g. Gleisdreieck).
