After cyclone AILA ripped the south-western part of Bangladesh two years ago, sea water keeps Koyra inundated twice a day as the major embankments remain broken. The continuous inflow of sea water has led hundreds of acres arable land into arid pasture where the bio-diversity is under threat. According to the agricultural scientists, it will take more than three to five years for the fallow lands to become cultivable again even after the embankments get fixed. Khulna, Bangladesh.
