The world's newest nation is both drying up and drowning

The worst floods in six decades have swallowed not only the very roads that people need to escape, but also their farms, homes and markets.

In this traffic, between the cities of Bentiu and Ding Ding, is a group of women, pushing to dislodge their makeshift raft that has become stuck in mud, weighed down by six children. The men in the family went back north to keep their cattle safe, and the women were left to push for four days in the hope of reaching higher ground. Along the way, their food ran out, said one of the women, named Nereka. Her 5-month-old baby wails as she talks.

"Of course, I'm worried about my children," she said. "That's why we keep moving."
