translate English to French: Draughts are the biggest killers – both in absolute and relative terms - even though a smaller proportion of population is exposed to them than to earthquakes; and even though they are not much more frequent than floods.
Les sécheresses sont les catastrophes qui font le plus de victimes – en termes absolus et relatifs – alors qu’une fraction de la population plus importante est exposée aux tremblements de terre et que les inondations ne sont pas beaucoup moins fréquentes.
