It is well known that, on average, poorer people live in places that are more exposed to flooding compared to richer people; this is known as ‘exposure bias’. The paper by Moulds et al.  is a collaboration between scientists at Imperial College London and the University of Sierra Leone. They have adapted a socio-hydrological model to simulate the effects that flood risk management interventions have on poverty and inequality. Besides showing that in general it matters a lot how flood risk management is targeted in urban areas, they explore the impacts on inequality demonstrating how pro-poor policies can reduce inequality as well as reducing flood risk overall. This is a significant step towards introducing social heterogeneity in socio-hydrological models.
