For the past two years, the rains have been poor in Somalia. What comes next is tragically familiar. Dry wells. Dying livestock. Failed harvests. Migration. Masses of people in dire need of humanitarian assistance. The same is happening in Yemen, Sudan, Kenya, Ethiopia, and Nigeria. However, poor rains are not the only water problem that creates havoc. Floods, water-borne diseases, and transboundary water conflicts can all cause severe human suffering and disruptions to political, economic, and environmental systems.
