The share of population that is flood-exposed and living under $5.50 per day
The share of population that is flood-exposed and living under $5.50 per day.

Among these people, 170 million are currently living in extreme poverty (less than $1.90 per day), and almost 780 million belong to some level of poverty (less than $5.50 per day). This study describes the magnitude of the issue and underscores the importance of having adequate flood mitigation strategies to prevent the impacts on livelihoods and the setbacks of development progress.

A few of the key findings:

  • Exposure to flood risk is substantial, particularly in low and middle-income countries.
  • Flood risk is global, but the most flood-exposed people live in South and East Asia.
  • When flood exposure and poverty coincide, the risk to livelihoods is most severe.
  • Relying on monetary risk estimates risks overlooking the areas most in need of protection.

Systematic risk mitigation measures are crucial to prevent the loss of lives and livelihoods and reversal of development progress.
