In December 2006, Indian researchers made an announcement that ricocheted through newsrooms worldwide: an inhabited island in the Sundarbans had disappeared beneath the water. Lohachara, a small islet in the Hooghly River's delta in West Bengal, had been home to hundreds of people -- media reports at the time cited inflated figures of 6,000 to 10,000 residents, but the actual 1991 census counted 374 inhabitants. Now it was gone. Headlines declared it the first inhabited territory claimed by rising seas, a harbinger of what awaited low-lying communities across the globe. Then, in April 2009, local newspapers reported something nobody expected. Lohachara had resurfaced. The island that was supposed to illustrate the irreversible consequences of climate change had, at least partially, risen from the water again -- turning a clean narrative into something far more complicated and, ultimately, more instructive about the forces reshaping the Sundarbans.

Understanding Lohachara requires understanding the plumbing of the Ganges Delta. In 1974, the Farakka Barrage began diverting water into the Hooghly River during the dry season, altering sediment flows across the delta's labyrinthine channels. During each monsoon, the lower delta...

No specific study was ever conducted to prove that Lohachara's submersion was caused by sea level rise rather than ordinary erosion -- a distinction that matters enormously for the climate debate but less for the families who lost their homes regardless of the mechanism. When the...

From above, the Sundarbans look like a green maze dissolving into brown water, the boundary between land and sea less a line than a negotiation. Lohachara's coordinates mark a spot in this liminal zone within the Sundarban National Park, where tidal channels branch and rebranch t...
