Go with the flow
The future is uncertain. It’s hard to know exactly how our climate will change. That means there is also deep uncertainty around its impacts on flooding, the most prevalent disaster worldwide. Floods account for 43% of all recorded disaster events in the past 20 years. Will climate change exacerbate flooding events? How much will sea level rise? How extreme will rainfall be?
What we do know is that the best way to cope with uncertainty is flexibility. While it may be difficult to predict impacts, we can – and must – take action. Growing uncertainty means preparation is even more urgent.
To meet future challenges, we need adaptable urban flood management today. Most flood management actions tend to be large, costly investments that have lasting consequences for society, such as the construction of enormous dams and dredging of drainage channels. Additionally, flood management plans are typically crafted to operate within a narrow range of conditions. — blog.wb.org/blogs
