People throughout the world are now becoming conscious of their heritages. And heritage includes a large number of varied things. It may be a special dialect, a dance, a musical tradition or even a hill, a forest, a river. A community's history can be intertwined with a small local river; a river may represent a country's tradition. There is no Vedic India without the river Saraswati or a later India without the Ganga. There is no Kalidasa without the Shipra river, no Bhatiali song without the river Padma. Similarly Bengal's history is linked with Adi Ganga.SAVE OUR HERITAGE RIVER : ADI GANGA
As Ganga represents a spiritual, cultural and historical continuity for this country, Adi (Old) Ganga evokes similar feeling for the southern parts of Bengal. People still call it Adi Ganga, the old Ganga River though the official name is Tolly's Nullah. The river branches out from the Hugli River, the present main course of Ganga flowing on the western side of the city of Calcutta. Kalighat, the city’s religious hub and one of the most important pilgrimage centres in the country, stands on the bank of Adi Ganga. Kalighat predates the city of Calcutta. It had been the main stream of the Ganga flowing towards the Bay of Bengal. The present course of Hugli river was then a part of now defunct Saraswati river (not the vedic one). Adi Ganga flowed southwards to meet Bay of Bengal through the middle of today's south Twenty Parganas district. In a number of old historical text, a large civilisation near confluence of Ganga had been reported. Gangaridae civilisation has been reported in first century Greek travelogues. In relatively recent times, there were a number of rich towns and religious places on the banks of Adi Ganga. Shri Chaitanya Dev, one of the major religious preachers of eastern India, travelled from north to Orissa through this way. The lower tract of Saraswati was connected (or probably re excavated) with Ganga near Calcutta nearly three centuries ago, to ease the upstream journey of the European merchant ships. This seems to be a major reason of dying of the Adi Ganga stream.
It was revitalised in 1772 by a British Major named William Tolly. He
excavated the course to open up the river route connection of Calcutta
with the districts of East Bengal. He therefore excavated the old channel
towards east to connect it with the Bidydhari-Matla river system. The
channel acted as a major navigation route for next hundred and fifty years.
The neglect of waterways in general and other factors like population
pressure and unplanned urbanisation etc. caused the silting of Tolly's
Nullah. It ultimately turned into a sewer channel for the southwestern
part of Calcutta. The channel which once had a number of bathing ghats,
temples, sacred cremation grounds on its banks has now turned into a stinking
sewer and source of all kinds of water borne diseases. Unauthorised shanties
have been built on both the banks as the city spread southwards. A number
of small factories, eateries and residences all dispose their waste of
all kinds in to the channel. The waterway is already gasping for life
with the human usurpation of its flowing course. At some places the course
has totally dried up.
The major difference for this new 8.5 kilometer extension will be a totally overground stretch running on an elevated track, quite contrary to the existing underground one. The Tollygunge- Garia section will run over the Tolly's Nullah. It has been reported that the railway track will be laid over a row of concrete pillars on the bed of Tolly's Nullah. Six out of the seven stations on this new stretch will be elevated stations. This will save Metro Rail from the difficult task of evacuating the squatters and paying compensation. The project will be completed in a shorter time, without much hassles. But this will exterminate the river, robbing its role as a navigable river for good.
Adi Ganga or Tolly's Nullah has recently become the focus of a number of community environmental initiatives. Shri Rebati Ranjan Bhattacharya has been campaigning for a decade to clean up this river and its banks. He has been a resident along its bank for decades and has witnessed the transformation of a river into a sewer. Tollygunge Development Council, a local welfare organisation, has also raised the issue of cleaning the channel. Considering a letter written by Shri Bhattacharya as a Writ Petition, a case was started in the Green Bench of Calcutta High Court in 1996. The High Court ordered the government to clean the channel and evacuate the squatters along its bank so that the river can be kept clean. It made a powerful committee headed by Chief Secretary of the State for expediting the work. Other members of that committee are the Chief Engineer of Calcutta Metropolitan Development Authority, the Commissioner of Calcutta Municipal Corporation, the Secretary of Irrigation and Waterways Department, and people like them.
While the community initiatives to clean this waterway was on, a report "Management of East Calcutta Wetland and Canal Systems” was prepared in March,1997 under Calcutta Environmental Management Strategy Action Plan (CEMSAP). CEMSAP was a multi-crore environmental planning project of Government of West Bengal, funded by British donor agencies. This report was prepared by some eminent experts in ecology, geography and irrigation engineering. To improve the capacities of existing canals, the report suggested connecting Tolly's Nullah with the decaying Piyali River as well as the moribund southern part of Bidyadhari River. This will permit controlled release of flushing dose of water from Hugli River into these rivers with a view to improving their cross-sections as well as that of down stream course of Matla River. This means a rejuvenated Tolly's Nullah can help to make alive the decaying river systems of southern Bengal.
The other important observation of the report was to integrate eco-tourism
and economy. It found significant scope of developing the canals for transshipment
of both goods and passengers and suggested Tolly's Nullah to be developed
for this purpose. Calcutta has a near circular canal system encircling
the city and its neighbourhood. Keshtopur canal on the north which meets
Bhangar Kata Khal and flows towards east can be connected with the eastern
extension of Tolly's Nullah by just excavating 11 kilometer of new canal.
A girdle canal of 42 kilometer long can be created which can be used both
for transport and tourism.
Adi Ganga meets all the criteria for being a Heritage River. It has a historical past linked with local culture and tradition. People still revere it as the original river. There is a strong community effort to rejuvenate the river. The experts have specific plans for its economic and environmental future. But all these may go in vain.
It is now time to raise voice to save the remaining portion of Adi Ganga. If the river can be rejuvenated with Ganga water, this can save the river system of South Bengal also.
Throughout the last decade the authorities in Calcutta have ignored the environmental considerations in the name of developing this city. Eastern part of Calcutta has been opened to unplanned rampant development, brushing aside their own experts’ recommendations. After the destruction of the wetlands and open spaces now it is the turn of a river to face the music. Metro Rail authorities seem to follow the same path of bartering the future for a myopic solution of some present problems. And what a river! The Heritage River of the city will be made into a pillar-riddled sewer.
Should culture-savvy Calcuttans silently accept the death of their heritage river?
