Aid workers in Mozambique's Sena area load family emergency kits into a boat on January 26, 2008. The cargo is to be delivered to people who have abandoned their homes and sought refuge in resettlement centers on the other side of the Zambezi River.

The flooded river has cut off many roads in the region.

Officials in Sena say that the floods have wiped out 35,000 acres (14,000 hectares) of cropland this year, up from 11,000 in 2007.

Food security has become one of the most pressing issues this year, though officials say the cyclical nature of the floods has taught them to be better prepared to handle the fallout.
