CLIMADA Climate Risk Analysis Urban flood resilience against riverine floods in Uganda and Nigeria

With increasing intensity and frequency of extreme weather events, climate change translates into unprecedented damages. This is especially true for communities in Africa. Detailed analysis of climate risks can help these communities to mitigate the risks and better prepare for the future.

This report discusses how applying climate risk analysis for Kampala/Uganda and Lagos/Nigeria demonstrates the useful information of the methodology applied. Investment and development decisions faced by governments, companies and households benefit by learning about:

• Expected damages and losses these districts will face due to riverine flood today
• How these risks will change over the coming decades and
• The cost-effectiveness of different adaptation measures to prevent and reduce these risks in order to strengthen their resilience against climate change.

Given the geographical similarities of the two African districts, climate risks will increase drastically for both by 2050. However, the results also reveal some interesting differences pointing once more to the importance to take the local context into account and break down national adaptation strategies to regional measures.
