I thought the March Puzzler would be an easy one, but it turned out to be one of the more difficult we’ve posted. As explained in our March 29, 2014, Image of the Day, the image shows Nalabana Bird Sanctuary in India’s Chilika Lake. Despite more than 50 guesses on Earth Matters and 500 on Facebook, nobody came up with the exact location. However, many readers (including Steve Martin and Wendy Spiteri) did recognize the shrimp farms or that it was somewhere in India.

I kept the caption to a  few paragraphs, but there’s a lot more that could be written about Chilika Lake. It’s a beautiful and fascinating place that faces environmental, economic, and political challenges that are as complicated as anywhere in the world. In 2002, for instance, authorities dredged a new connection with the Bay of Bengal after silt narrowed the existing mouth and made it more difficult for salty water to enter the lake. While the new mouth increased salinity levels, it did little to resolve the pitched debate between shrimp farmers and traditional fishing communities that has simmered for years. In 1996, the Supreme Court of India banned aquaculture within 1,000 meters (3,300 feet) of Chilika Lake because of environmental concerns, yet enclosures known as “gheries” (which are even visible to satellites…see page 50 of this Powerpoint) remain widespread. You can read more about the ongoing debate about aquaculture in Chilika Lake from Infochange, Economic Times, Radio Netherlands, and the Times of India.

Flickr user Adita Pany took the photograph of flamingos at Nalabana shown above in 2007. The QuickBird satellite caught a glimpse of a stand of flamingos near Nalabana in 2005.
