Kadalundi, on the south-west coast in Kerala, had about 8 hectares of nutrient-rich inter-tidal mudflats in the early 2000s.
Now, the expanse of mudflats in the estuary of the Kadalundipuzha river has reduced to just about 1 hectare.
This too is gradually being covered with sand, depriving prey to thousands of shorebirds that migrate from colder climes in winter to Kadalundi village in Kozhikode district.
Kadalundi is in the global map as a prominent destination of migrant shorebirds.
