Niger's government needs another 45 billion CFA francs ($85.24 million) in food aid after a new survey found 500,000 more people than previously thought will face severe food shortages this year, the government said. The new survey, carried out in April and published on Thursday, showed that 3.3 million people, or 22.2 percent of Niger's population, are facing severe food insecurity. Previous estimates put the figure at 2.7 million.
