Ahead of monsoon season, the UN World Food Programme in late April and early May helped Rohingya refugees in Cox’s Bazar, Bangladesh, prepare their camps for potential flooding.

The preparations included efforts to secure food distribution points, e-voucher shops, and roads, and to stabilize slopes in high-risk areas and clear drainage canals, the WFP said.

The organization also said it urgently needed $213 million “to feed more than 800,000 Rohingya refugees in Cox’s Bazar for the rest of 2018.” A quarter of those 800,000 refugees were at serious risk of flooding and mudslides and an estimated 30,000 refugees would be relocated to hills, valleys and steep slopes, the WFP said.

This footage, provided by the WFP, first shows children playing and walking through an area the organization said became flooded after just a few hours of rain. Also shown are Rohingya refugees, paid by WFP, clearing high ground, fields, and building a logistics base the WFP said would “help respond to the upcoming heavy rains and storms.”

“Hundreds of Rohingya workers are involved every day in Food Assistance for Assets (FFA) activities in exchange for a cash transfer that also improves the food needs of their families,” the WFP said. Credit: World Food Programme (WFP) via Storyful
