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.

Dakar’s urban population is exploding with an annual growth rate of 2.5% and urbanisation rate of 97.2%. ONAS, the National Sewerage Company, is improving faecal sludge management (FSM) services in urban and peri-urban areas.

City of Kunshan

Kunshan, a city in the north-west of Shanghai, China, that inhabits more than 1.6 million people, is one of the most economically successful county-level administrations in the Jiangsu Province. Kunshan with its complex landscape is a “Water city” that has more than 100 polders and over 1000 km of waterways connected via pumps and gates.

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.
