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.

Perth is on the frontier of extremes, isolated from all other major cities in Australia on the largely wild west coast. Perth’s declining water availability from both surface and groundwater sources is well recognised.

Yorkshire Water

Melbourne is the state capital of Victoria and Australia’s second biggest city. Facing a variable climate; the region is facing more periods of extreme heat and drought, reductions in annual rainfall and increases in intense rainfall events.

Skanderborg Forsyning

The Danish water utility Skanderborg Forsyning affirms that when it comes to water security in a changing climate, using nature-based solutions at the local level was never a question. Climate change projects are an opportunity to adapt using nature to deal with increased rainfalls and prevent the flooding of urban areas.
