It was when the body of a long-dead friend surfaced near her front door that Bulu Haldar knew her house was as good as gone.
For weeks, the embankment shielding East Dhangmari, in the Khulna district of southwestern Bangladesh, had been threatening to sink into the Pusur River. First, a ferocious storm had ripped into the outer layer of concrete. Then, at the end of 2017, the river had begun eating into the porous earthen wall itself. Locals rushed in sandbags, but that bought only a few days' respite. When the river finally surged into the cemetery across from Haldar's garden, disinterring skeletons and contaminating the village's drinking pools, it filled her one-room hut waist-deep in muddy brown water.
