Two U.N. agencies say food production in Syria has shrunk to "an all-time low," threatening to drive more people from their homes after 5-1/2 years of war.

The World Food Program and the Food and Agricultural Organization say factors like rising prices, poor weather, general instability and the lack of fertilizer and seeds could force some farmers to stop producing.

A joint report released Tuesday says the planting area in the 2015-2016 season was the smallest ever in zones controlled by the government, ethnic Kurds and the armed opposition. WFP spokeswoman Bettina Luescher said information was lacking about areas controlled by the radical Islamic State group.

FAO regional representative Abdessalam Ould Ahmed said 80 percent of households lack food or money to buy it.
