The humanitarian impact of the 2015-2016 El Niño remains deeply alarming, now affecting over 60 million people. Central America, East Africa (particularly Ethiopia), the Pacific and Southern Africa remain the most affected regions. The El Niño phenomenon is now in decline, but projections indicate the situation will worsen throughout at least the end of the year, with food insecurity caused primarily by drought not likely to peak before December. Therefore, the humanitarian impacts will last well into 2017 .

AFRICA: In eastern Africa, heavy rains and floods have caused loss of life and destroyed crops and infrastructure in several countries. However, prospects for current crops have improved. In southern Africa, cereal import requirements in 2005/06 (excluding South Africa) are estimated about 30 percent higher than last year due to substantially reduced harvests in Malawi, Zambia and Zimbabwe. South Africa, on the other hand, is estimated to have more than enough exportable surplus of maize to meet the import needs of the subregion.
