The Sunderban spanning both in India and Bangladesh contains the world's largest region of mangrove forests. The Indian side of Sunderban, is covering about 9,630 sq. km. The area is rich in marine as well as fresh water flora and fauna.
Sundarban is also the largest tiger reserve and home of famous Royal Bengal Tiger. The area is part of the world’s largest delta (26,000 sq. km.) formed from the sedimentation of three large rivers, the Ganges, Brahmaputra and Meghna. These three rivers converge on the Bengal Basin. Looking at its rich biodiversity, Sunderban was recognized as a biosphere reserve and awarded the status of a World Heritage Site in 1997 by the UNESCO. .
Sahara India group signed a Memorandum of Agreement (MoA) with the West Bengal government in November 2003 for jointly implementing a tourism project in the Sundarbans. This MoA was signed to make Sundarban as the global tourism hub, accommodating about 75% on the floating Boat houses and 25% on-shore cottages, huts and tents.
The complex would equipped all modern recreation facilities to explore the creeks of the deltaic estuary .
According to the then Chief Minister of West Bengal Mr Buddhadeb Bhattacharjee the State cabinet had taken a decision to provide the Sahara group with land necessary for the project. The initial estimated cost of the project was about Rs 500 crore. The Sahara project is proposed to be located mostly in the buffer area of the Sundarban Tiger Reserve . The company assured direct and indirect employment of thousands of people. Besides, the project is said to bring about overall development in surrounding areas."  The proposed project will affect the livelihood of local fisherman community who are dependent on the fishing for the generations in the areas. As an initiative to give land to Sahara Group, over 10,000 Sunderbans fishermen were evicted from Jambudwip Island by the West Bengal government in 2003-2004. Also, government put a ban on fishing in the area. As a result fishermen had been unable to fish because of the ban. Even the fish drying activities on the sea shore had been stopped, while the government had claimed these activities were going on in alternative sites .
Because of the protest from the various groups as well as local farmers, fishermen and villagers the Sahara Project was shelved. However, the project was not been officially discarded. Many other big investors also shown their interest in Eco tourism project in Sundarban. Government had also shown its interest to such kinds of Mega Tourism in Sundarban .
