    Polder 32

    Polder 32 is one of the many inland islands in Bangladesh that was enclosed by an embankment to protect it from flooding. When that embankment failed during Cyclone Aila in 2009, the island was flooded for almost 2 years. Subsidence of the ground inside the embankment with no sedimentation to compensate made it worse. We…
