There is a forest at the northern end of the Bay of Bengal. It is a forest like no other and spread over a vast area where two of South Asia greatest rivers meet the sea after their long journey from the high Himalaya. The Sunderban is this vast, 10,000 square mangrove forest and it’s a place that in the 21st Century still embodies wilderness in its rawest, most beautiful and sometimes terrifying form.  Political boundaries separate it between Bangladesh and India but once inside the maze of mangrove trees there are few signs of any human presence. The area hosts impressive plant and animal diversity and is well as one of the most secure locations for wild tigers to breed in.

For the last 40 years NASA satellite shave been imaging the Sunderban and the results have produced some of the most enigmatic images of the earth’s surface. With the Landsat data achieve now available for public use I have been exploring recent imagery from the Landsat 8 satellite. The data that I processed and displayed in the above image is very fresh- it was collected in late January and early February this year by Landsat 8. It’s given me a chance to virtually revisit a forest that was once a favorite place to go to for birding and photography expeditions.

This book is produced by the most authoritative people on the Bangladesh Sunderban. This include Rubaiyat and Elizabeth Mansur and their colleagues Dr. Gertrud Neumann-Denzau and Dr. Helmut Denzau. I had the privilege of interacting with them all on several memorable trips into the Sundarban.

The Guide Ltd. The best way to visit the Bangladesh Sunderban is with the family-run Guide Tours travel agency. Hasan Mansur and his family have been helping people to experience the Sunderban intimately for 20 or so years. I owe all of my best experiences there to them.

Note on etymology of Sundarban: there is some variation on the ways that Sunderban is spelt base on the source. The name can either be literally translated from Bengali as the “beautiful forest” or as a distinct name based on the dominant Sundari (Heritiera fomes) tree.

  1. There are now discussions around building multiple dams on the Bramhaputra (with one already built, AFAIK). How is it likely to impact the Sundarbans?
