Over 50% of the world population lives in cities. More than two thirds of the world's largest cities are vulnerable to rising sea levels as a result of climate change. Millions of people are being exposed to the risk of extreme floods and storms.

The goal of Connecting Delta Cities is to develop a network of delta cities that are active in the field of climate change related spatial development, water management, and adaptation, in order to exchange knowledge on climate adaptation and share best practices that can support cities in developing their adaptation strategies.
