Water Sensitive Urban Planning in times of Climate Change

2023 - UCLG Peer Learning Note #33




Heavy rain and storm water events such as those in the Ahr Valley in Germany in 2021, or in Pakistan, Australia and South Africa in 2022, cause streams to swell to raging torrents, flood roads, destroy houses and bridges and lead to loss of life as well as damage worth billions. They occur suddenly and can only be predicted in the short term. According to a study supported by the World Bank, flood risk already affects 1.81 billion people, more than 20% of the global population, most of them in poor and middle income countries.

In consequence, local governments and municipal leaders, planners and service providers look for more integrated and inclusive solutions to avoid human, environmental and financial losses related to flood.

This Peer Learning Note (PLN) documents the practices and discussions shared between cities and partners during the Connective Cities Dialogue Event “The Role of Rain and Storm Water Management in Water Sensitive Urban Planning”, which took place from December 6-8, 2022 in Cologne, Germany.
