Camp managers and other local officials overseeing Rohingya refugee camps in Bangladesh are now incorporating NASA satellite observations into their decision making in order to reduce the risk to refugees from landslides and other natural hazards. Information like daily rain totals can help inform how to lay out refugee camps and store supplies. More than 740,000 Rohingya refugees have fled to Bangladesh since August 2017. Many of them have sought shelter in camps located in the hilly countryside, where landslide risk may be the greatest. Increasing this danger is Bangladesh’s intense monsoon season. Approximately 80 percent of Bangladesh's yearly rain falls in just five months, from June to October, bringing with it an increased risk of flash flooding and landslides.

Rainfall was scarce across much of the country in the month of September, pushing the eastern and southern thirds of the country into drought conditions.
