Resilience is more than income – lessons from Accra’s 2015 floods

Stéphane Hallegatte and Alvina Erman (WORLD BANK)


In June 2015, after two days of heavy rain, flood water washed away Sarah’s small store in Accra, which provided for her family of three. The flood that hit the city in June 2015 affected around 53,000 people in the city and caused an estimated US$100 million in damages. Slum areas in the Odaw basin were among the worst hit.


The informal settlement of Sabon Zongo was among these areas, and this is where Sarah’s house and business were located. It took Sarah 3 months to rebuild her business. During this time, she had to repair the shop and replace the produce, although she wasn’t making any money. With no savings, Sarah was lucky to get a loan to cover these costs.






Her neighbor Mohammed, a single man in his early 40s, was also affected. Being relatively better-off, he was better prepared to respond to the shock. His business selling cool beverages out of his home came to a halt when the flood water damaged his industrial fridge. By tapping into his savings, he quickly bought a new fridge and could reopen his business after one week. Replacing Mohammed’s fridge cost much more than fixing Sarah’s small convenience store, but the impact of his loss was much smaller.

What do these stories tell us about the relationship between poverty and flood risk in Accra? They confirm the main message of our Unbreakable report, namely that the direct impact of the flood on an individual is a poor predictor of the real effect on her or his well-being and livelihood.

They also suggest that managing flood risks requires a better understanding of how floods affect poor households and the coping mechanisms they use to deal with floods. To be able to efficiently target post-disaster support and design policies to strengthen vulnerable populations, we need information about those who suffered the most.

To go beyond individual cases and anecdotal evidence, we recently performed a large household survey in several slum areas located in the Odaw basin in Accra, asking people about their experience of the 2015 floods.

Today, we publish the results of this analysis, in a paper that assesses the role of poverty in exposure to flood risk (“Who is affected by the flood?”), the vulnerability of the population and assets (“How much did the affected people lose? What type of losses did they experience”), and the socio-economic resilience of the population (“Was the affected population capable of coping with and recovering from the losses?”).
