"Here in Marseille, aid groups like Action Contre La Faim (Action Against Hunger - ACF) are patting themselves on the back for pushing the issue of water-related humanitarian emergencies higher up the political agenda, saying they've made it to the heart of World Water Forum discussions for the first time...ACF President Benoît Miribel agreed that 'disasters are happening where there is already a disaster', whether it's a scarcity of water or bad sanitation, leaving some countries and communities in 'a permanent state of disaster'. Another issue that is often neglected in crisis situations is the disposal and treatment of wastewater, Miribel said."
