Parvin Begum, who saw her home on a secluded island in northern Bangladesh steadily devoured by floods this month, feels lucky.

She received some money before the disaster hit under a new form of aid, used for the first time in Bangladesh by the government and humanitarian agencies.

It gives funding to vulnerable people in advance of extreme weather, based on forecasts, so they are better prepared. With her cash, Begum bought food, rented a boat, and took her belongings to a government shelter on a nearby island before the rising water crossed the danger level.
