	Making cities resilient to floods
 About 44% of all disaster events around the world are flood-related.
 In our new explainer episode, we show how ‘sponging’ cities can help them overcome the challenge of flooding while strengthening the local ecology, and boosting the economic and social well-being of residents.
 In this episode, you will learn:
 1. What a sponge city is (and how it works)
 2. The benefits of ‘sponging’ cities (beyond flood-resilience)
 3. Projects that demonstrate the principles and benefits of a sponge city at various scales (and what we can learn from them)
 4. Why developers should be in favour of sponge city initiatives (they can save millions in costs)
