A new U.N. report says 34 countries, nearly 80 percent of them in Africa, don't have enough food for their people because of conflicts, drought and flooding.

The Food and Agriculture Organization's Crop Prospects and Food Situation report released Wednesday says drought associated with El Nino has "sharply reduced" 2016 crop production prospects in southern Africa.

In areas of Central America and the Caribbean, the report says dry conditions linked to El Nino may affect the planting of crops for the main growing season for the third consecutive year.

The report says expectations for harvests in Morocco and Algeria have also been lowered due to dry conditions.

FAO's first forecast for wheat production in 2016 is 723 million tons. That's 10 million tons below the record output in 2015.
