According to a new study in the Proceedings of the National Academy of Sciences, global warming-fueled droughts could reverse recent gains made against child malnutrition by stoking food insecurity. Researchers used data on more than 580,000 children in 53 countries, as well as satellite images of drought conditions since 1990, which revealed that countries like Chad, Sudan, Somalia and Yemen are being hit hardest. Malnutrition is responsible for nearly half the deaths of children under the age of 5.
What could be done? Besides basics like improving local governance and boosting irrigation, experts say promoting nutritionally diverse farming methods would also go a long way.
