Consequences of climate change for large cities in deltas
What are the threats affecting large cities in the most important estuaries of the world?
To answer this question, the Dutch research institute Deltares has conducted an extensive study of eight delta regions, the results of which will be discussed at Aquaterra 2009. The study focuses especially on climate change, which will affect coastal cities disproportionately.
Three types of water-related problems
There will be increased pressure related to water from three different directions:
- from above – heavier rainfall will cause more flooding
- from the hinterland – rivers will carry more water downstream through the cities
- from the sea – water levels will rise and violent weather will cause more and more storm surges.
Large cities in deltas
The Dutch research institute Deltares has carried out a unique study in partnership with Aquaterra into eight of the world’s key estuaries. The results will provide plenty of subject matter for various discussions during Aquaterra 2009. While the relevant deltas may be different in various ways, each is characterised by dense habitation, and some include very large cities. The Deltares study covers:
- Rotterdam, Rhine delta
- New Orleans, Mississippi delta
- Sacramento, California Bay
- Alexandria, Nile delta
- Ho Chi Minh, Mekong delta
- Djakarta, Ciliwung delta
- Jinan, Yellow River delta
- Dhaka, Ganges/Brahmaputra delta
