Droughts are among the natural hazards with the highest adverse impacts on human populations . Although droughts represented just 4% of hazard events, their impacts amounted to 31% of affected people  . Drought exposure relates to a higher risk of undernutrition , among vulnerable populations , particularly children  for whom the impacts can lead to lifelong consequences through stunted growth, impaired cognitive ability and reduced future educational and work performance . The corresponding costs of children stunting in terms of lost economic growth can be of the order of 7% of per capita income in developing countries .
