Oil spill on the shores of Chennai (Source: indiatimes.com)
.
A large quantum of thick and dark oil washed ashore from Bharathiyar Nagar beach in Ernavur to Marina Light House in Chennai. Tonnes of tar-like thick black oil has polluted several square kilometres of sea in the Bay of Bengal.
According to fishermen, tar-like thick oil started to collect near the shore from Saturday evening. Fishermen around Marina complained that they found it difficult to navigate their boats in the sea because of the thick oil deposits. The fishermen are demanding compensation for loss of livelihood.
The Tamil Nadu Pollution Control Board officials said the spill could be the result of the accidental collision of two ships, the inbound vessel MT Dawn Kanchipuram and the outbound vessel LPG/CBW Maple in the wee hours on Saturday at Ennore port’s anchorage.
“There was a collision between a LPG tanker vessel, BW Maple, Isle of Man flagship, and vessel MT Kancheepuram, an oil and chemicals tanker, on the outskirts of Ennore at 4 am (on Saturday). So, this could be a result of that. As it is so thick, we are not able to find out what type of oil it is. We are conducting an investigation,” said a senior official.
While a statement from Kamarajar Port claims that there was no damage to the environment, or casualty or injury, the Times of India reported that the Tamil Nadu Pollution Control Board, Darya Ship Management and Kamarajar Port have been held responsible for damage to the environment.
The New Indian Express reports:
“The biggest challenge was that both Kamarajar Port and the vessel that caused the disaster remained in denial, leaving the official machinery clueless about what they were dealing with. Minister of State (Shipping) Pon Radhakrishnan visited the port and observed that ‘there were no spills/sheens in the area’, claims a release from the port.”
By Sunday morning the dark thick stagnant oil spread southward about 25km from the outskirts of Ennore where the accident occurred polluting several beaches, including the iconic Marina Beach in Chennai and beyond.
Now, the oil has converted sandy beaches, including the Marina, into a slushy ground, making it inaccessible to the public. Oily sludge. coats the rocks on the coast.
The mild smell of salt and fish that wafted in the air in the neighbourhoods along the beach has been replaced with a heavy, pungent emanation of petroleum and tar.
Hordes of fish and many turtles and hatchlings covered with thick oil were found dead near Ernavour and some were found washed ashore at Marina Beach.
According to environmental experts, the spill could have a long-lasting adverse impact on marine life. The shoreline is known for Olive Ridley turtles which nest on local beaches between January and April every year.

Now, the ill-equipped pollution response teams of the Indian Coast Guard are carrying out an impossible mopping operation. As the Indian Coast Guard lacks the technical expertise, the authorities have invited private companies to bid for the cleanup work.
Why am I interested in wetlands and writing about them?
Because I am concerned.
My home in Jalladianpet in Chennai, Tamilnadu, India is just 2.5 miles (4 km) from the Pallikaranai wetland. Now, this once pristine idyllic wetland and many other smaller wetlands, pasture lands and patches of dry forest in Chennai are being transformed into concrete jungles!
That is why I am concerned.
I am not an environmentalist per se. I am just a layman. I seek protection of our natural environment from changes made by harmful human activities. I yearn for improvement in the quality of our surroundings worldwide for the benefit of our present and future generations.
.
My home in Jalladianpet is just 2.5 miles (4 km) from the Pallikaranai marsh.
.
The Pallikarani wetland serves as nature’s primary aquifer recharge system for Chennai city. It harvests rainwater and the flood water during monsoons and thereby mitigates the desolation and suffering that floods could cause in low-lying areas in Chennai.
Four decades ago, this pristine idyllic wetland had a water spread of approximately 5,500 hectares estimated on the basis of the Survey of India toposheets (1972) and CORONA aerial photographs (1965).

.
Lamentably, over the years, the Chennai Metropolitan authorities without giving any thought to the future recklessly chose to dump almost 2,600 tonnes of garbage per day, which is over one-third of the garbage of the ever-growing metropolis, here in this climatic marshland.
.

Now, the water spread has shrunk to one-tenth its size due to indiscriminate dumping of city refuse; discharging of sewage; disgorging toxic waste products, etc.
Many nature lovers have photographed the current palpable and saddening state of the Pallikaranai wetland. On June 8, 2013, The Hindu published the article “The mired marsh” by Shaju John. He has augmented his article with photographs captured by him in the post-Photo file: The mired marsh.

While traveling along the roads around the Velachery wetland one encounters the unbearable stench emanating from the decaying garbage hillock. Despite the widespread clamour to stop burning rubbish in the dump yard that stifles the air and impairs visibility of commuters, the incessant burning goes on.

Air samples from the Perungudi garbage dumping yard registered the highest number of chemicals found in any Indian sample. The air contained cancer-causing and other harmful chemicals.
People living miles around the Pallikaranai wetland continually inhale the omnipresent malodorous virulent air. They suffer the stifling smoke. They have no other alternative than to use the polluted and poisoned ground water. These factors subject them to major wheezing and carcinogenic health hazards.
On June 15, 2012, a concerned Jaison Jeeva uploaded the following video on YouTube. It shows the fire accident that happened at the garbage dumps in Pallikaranai. The incident caused physical and mental disturbance to the people in the vicinity.

All these encroachments have led to building infrastructures such as the Velachery MRTS railway station, the flyovers, the road connecting old Mahabalipuram Road (OMR) and Pallavaram, etc., in the midst of the marshland.
Sadly, all these rampant developments have shrunk the water spread.
With policies in place to crack down on encroachment, illegal waste disposal, and poaching, there is still hope for saving the Pallikaranai wetland.

Even so, it is the opinion of the scientists and researchers involved in the study of the wetland that an additional 150 hectares of undeveloped region located on both sides of the road connecting old Mahabalipuram Road (OMR) and Pallavaram that bisects the marsh should also be declared a forest reserve.
An official release on Friday, June 9, 2006 the Tamil Nadu Pollution Control Board (TNPCB) underscores the need to protect the rare species of fauna and flora in the ecologically important wetland of Chennai.
.
Dumping sewage into the Pallikaranai marshland.
.
To retain the groundwater recharging potential the TNPCB banned the dumping of garbage and discharge of sewage and industrial effluents into the Pallikaranai marshland. The TNPCB directive states that untreated sewage should be discharged only into the sewage treatment plant operated by Metrowater at Perungudi. The TNPCB warned that violators of its directions would be Penalized without prior notice under section 15 (1) of the Environment (Protection) Act, 1986.
On June 10, 2006, The Hindu in an article titled “Dumping banned in Pallikaranai marsh” said:
The punishment under this section involves imprisonment for a term, which may extend to five years or with fine, which may extend to Rs.1 lakh, or both. In cases of repeated violation, the penalty involves additional fine, which may extend to Rs. 5,000 for every day during which the contravention occurs, after the conviction for the first violation.
Further, if the violation continues beyond a period of one year after the date of first conviction, the offender is liable to be imprisoned for a term that may extend to seven years. According to the press note, the basis of the directive is a routine inspection of the Perungudi dump site and the marsh zone by the TNPCB, which found that unsegregated garbage along with other wastes emptied into the marshland by the Chennai Corporation and other local bodies as well as private agencies. This garbage is burnt by ragpickers, causing nuisance to the residential areas and setting off air-pollution. The inspection also observed that untreated sewage collected from nearby areas in tanker lorries was being discharged into the marshland.
The TNPCB has also constituted a Local Area Environment Committee to protect the marsh. The public can refer any complaint on discharge of sewage or solid wastes into the marsh area by any agencies to this committee through the District Environmental Engineer, TNPCB, Tambaram (Phone 22266239). The Pollution Control Board’s announcement comes just days after a non-governmental initiative released the results of a recent study on air quality.
In April 2008, the Madras High Court directed the State Government of Tamilnadu to remove all encroachments on the Pallikaranai marshlands. The Madras High Court also directed the Chennai Corporation not to allow the four municipalities – Pallavaram, Madipakkam, Kottivakkam and Valasaravakkam – to dump garbage at Perungudi after April 30, 2008.
On April 3, 2008, The Hindu in an article titled “Court directive on Perungudi garbage dump” said:
Passing interim orders on two writ petitions, the Bench said the State Government should not permit any construction activity on the marshlands. The court appointed a six-member expert committee, with Sheela Rani Chunkath, Chairperson, TIIC, as its convener to inspect the Perungudi Municipal Solid Waste Yard, CMWSSB treatment plant and the surrounding areas and submit a report regarding the suitability of the present site for usage and the continuance as a municipal solid waste ground and sewage treatment plant; to review compliance of various legislations, guidelines, rules and regulations in relation to dumping of solid waste and discharge of sewage; to review the earlier studies done by various agencies, and the measures taken and proposed to protect the Pallikaranai marsh and render suggestions for restoration and protection of the marsh.
The committee would also suggest measures for remediation of the land, ground water, flora and fauna in the marsh and Seevaram, Pallikaranai, Thoraipakkam and Perungudi villages. It would also consider the cumulative aspects of dumping of garbage, discharge of sewage and conversion of the marshlands to other use and suggest scientific alternative methods of dumping of garbage and discharge of sewage in the light of the methods in other countries.
The committee would conduct public hearing to ascertain the views of the residents of the four villages. The report should be made within six months, the Bench said.
Pending receipt of the report, the Chennai Corporation was directed not to permit their trucks to dump garbage on either side of the road and to remove the garbage already dumped on either side of 60 Feet Road abutting the residential areas and also the 200 feet road, within four weeks. It should demarcate the area of 200 acres which had been allotted to it by CMWSSB and further demarcate 106 acres which was actually used for dumping waste. Security at the dumping site should be increased to prevent incidents of fire. Appropriate scheme for segregating biodegradable and non-biodegradable wastes should be evolved and submitted to the court within three months.
…
The Tamil Nadu Pollution Control Board in its report in respect of the landfill at Perungudi submitted that the Chennai Corporation had not complied with the Municipal Solid Wastes (Management and Handling) Rules, 2000.
Seven years have passed since then, but even now, dumping of garbage and sewage in the Pallikaranai marshland by the Chennai metropolitan authorities goes on unabated.

What is a wetland?
A wetland is technically defined as:
“An ecosystem that arises when inundation by water produces soils dominated by anaerobic processes, which, in turn, forces the biota, particularly rooted plants, to adapt to flooding.“
Wetlands consist of hydric soil, which supports aquatic plants. The primary factor that distinguishes wetlands from other landforms or water bodies is the characteristic vegetation that adapts to its unique soil conditions and the fauna that inhabit it
There are four main kinds of wetlands: marsh, swamp, bog and fen. Sub-types include mangrove, carr, pocosin, and varzea. Some experts also include wet meadows and aquatic ecosystems as additional wetland types. (Read my article: Save the Wetlands)
Wetlands of Tamilnadu, India
There are three wetlands in the state of Tamilnadu, in India: Point Calimere, Kazhuveli, and Pallikaranai.
In 1985-86, the National Wetland Conservation and Management Programme (NWCMP) of the Government of India listed Point Calimere, Kazhuveli Wetland, and the Pallikaranai Marsh among the 94 identified wetlands in India.
Point Calimere, Kazhuveli wetland, and the Pallikaranai wetland are three of the 94 identified wetlands under
The forests of Point Calimere
Point Calimere, also called Cape Calimere (Tamil: கோடியக்கரை Kodiakkarai), is a low headland on the Coromandel Coast, in the Nagapattinam district of the state of Tamil Nadu, India.
The forests of Point Calimere are also known as the Vedaranyam forests. They are the last remnants of the East Deccan dry evergreen forests.
.

.
On June 13, 1967, the Point Calimere Wildlife Sanctuary with an area of 24.17 square km was created. The sanctuary includes the cape with its three natural habitat types: dry evergreen forests, mangrove forests, and wetlands.
The Kazhuveli wetland
Kazhuveli the second largest brackish water lake in South India lies adjacent to the Bay of Bengal along the East Coast Road. It is located about 18 km north of Pondicherry in the Tindivanam Taluk of Villupuram district in Tamil Nadu.
Once a mangrove forest, Kazhuveli, has degraded over a period of time. It encompasses about 15 villages with a catchment area of 4,722 hectares. A total of 196 minor irrigation tanks and ponds drains into the Kazhuveli wetlands.
Now, the entire ecosystem of Kazhuveli wetland is completely destroyed and denuded by human inference, chiefly, due the growth of salt pans and aggressive fishing. It is one of the prioritized wetlands of Tamil Nadu.

The Pallikaranai wetland is among the few and last remaining natural wetlands of South India.
Historically, a large part of South Chennai was a flood plain composed of the large Pallikaranai wetland, smaller satellite wetlands, large tracts of pasture land and patches of dry forest.
The Pallikaranai wetland is a freshwater marshland spanning 31 square miles (80 square km). It is the natural primary aquifer recharge system for Chennai city.

The Pallikaranai wetland situated adjacent to the Bay of Bengal, is about 12.5 miles (20 Km) south of the city centre. Bounded by Velachery (north), Okkiyam Thuraipakkam (east), Medavakkam (south) and Kovilambakkam (west), the Pallikaranai wetland is the only surviving wetland ecosystem of the city.

The terrain consists of fresh/saline water bodies, reed beds, mud flats and floating vegetation.
The original expanse of the Pallikaranai wetland, estimated on the basis of the Survey of India toposheets (1972) and CORONA aerial photographs (1965) was about 5,500 hectares. This vast area has now been reduced to about 600 hectares.
Flora and Fauna
Vedanthangal bird sanctuary in the Kancheepuram District in Tamil Nadu, India, is 47 miles (75 km) from Chennai. It hosts more than 40,000 birds (including 26 rare species), from various parts of the world during the migratory season every year.
Now, Pallikaranai wetland is almost four times the size of the Vedanthangal bird sanctuary and is literally a treasury of bio-diversity.
The Pallikaranai wetland has several rare and endangered species of flora and fauna. The marsh acts as a forage and breeding ground for thousands of migratory birds from various places within and outside the country. Bird watchers opine that the number of bird species sighted in the Pallikaranai wetland is definitely more than what they get to see in the Vedanthangal bird sanctuary.
Figures of the number of fauna and flora found in the Pallikaranai wetland differ among scholars conducting research here.
Among the many quiet contributors to the mapping of India’s natural treasures is Dr. Jayashree Vencatesan, Smithsonian Fellow and researcher, and managing trustee of Care Earth Trust. She obtained a Ph.D. in Biodiversity and Biotechnology from the University of Madras. She is best-known for her research work on biodiversity and studies in wetland ecology.
Dr. Jayashree Vencatesan
In 2003, the Tamilnadu State Pollution Control Board assigned to Dr. Jayashree Vencatesan the task of conducting a detailed study of Chennai’s last remaining wetland – the Pallikaranai marsh, which is suffering from degradation caused by human impact. The study had two components – to document the biodiversity and to map the extent of the marsh to define or identify a viable unit of management.
In her work “Protecting wetlands” published on August 10, 2007, Current Science 93 (3): 288–290, she states that the heterogeneous ecosystem of the Pallikaranai marshland supports about 337 species of floras and faunas:
Birds, fishes and reptiles are the most prominent of the faunal groups.
Dr. K. Venkataraman
However, on August 9, 2013, P. Oppili reported in The Hindu that Dr. K. Venkataraman, Director of Zoological Survey of India (ZSI) while discussing the diversity of species in the marshland, as nine species of amphibians, 21 species of reptiles, 72 species of birds, five species of mammals, 38 species of fish, nine species of shells and 59 species of aquatic and terrestrial insects had been recorded, besides a good number of plankton.
The Pallikaranai wetland is the home to some of the most endangered birds such as the glossy ibis, gray-headed Lapwings and pheasant-tailed Jacana.

About 114 species of plants are found in the wetland, including 29 species of grass. These plant species include some exotic floating vegetation such as water hyacinth and water lettuce.
Since 2002, presence of new plants and reptiles have been recorded.

Since 2002, presence of new plants and reptiles have been recorded.
Heaven is here. Keeping your surrounding clean is a sin.

Dear Uncle Raj,
Greetings from Joe!
This morning around 6 a.m., the train stopped at Katpadi station for a long halt. My hunger kicked me out to buy something to eat to break my fast.
I walked on the platform towards the engine and found a stall where I bought a bottle of mango juice and a pack of breakfast neatly packed in a paper carton box with silver foiled coating. It had 3 idlis and 1 small vada, accompanied by sambar and a mint chutney.
I rushed to my coach, closed the screens on my coupé and started gobbling them, unsure of the taste, but to tackle my growling tummy. The sambar although sucked, the mint chutney definitely needs a great mention.
When I was done, it was time to trash it.
I searched thro’ the compartment for a trash-can or a bin, but failed in vain.
I went into the toilet and there was no bin.
I got down on the platform, walked around like a vagabond searching for a bin/trash-can.
Walked thro’ front and back along-side the train in-search of a trash-can, but failed again in vain.
At last, I was forced to throw my trash on the adjoining track, which was already a trash-dump.
I felt awkward and humiliated. I had no other option. I returned to my seat.
Now, people in India are bent on globalization. They are emulating US and the European countries, by changing their culture and habits. Indians now eat at KFCs & McD’s, wear Hugo Boss & Gucci, drive Mercedes, BMW, Porsche & Maserati; but are not worried about their civic responsibilities, and do not have to the inclination to keep their environment clean and hygienic.
Is the enforcement needed to tell us not to spit, shit, and litter anywhere we like, especially in public places?
When I look around here in India – be it a village, a town, a city, or a metro – I see nothing but heaps and mountains of trash. Here, one is free to throw whatever garbage wherever and when. It is the done thing. To many, keeping one’s surrounding clean seems to be a sin.
I’m honestly doubtful if India could attract tourists from other countries with such a slovenly begrimed environment. If US was dumped like a dumpster (as India is portrayed here by me), will our NRI folks stay for long over there?
I’m feeling more stressed-out in the last couple of days after coming here with all these happening around me.
If only there is a sense of civic duty in everyone’s mind and if basic amenities as simple as a trash can be provided in public places then we can truthfully say, “Heaven is here… in India.”

Dear Uncle Raj,
Greetings from Joe!
I’m writing this email to share my experiences with you on how one’s hands are clamped from being more responsible towards one’s civic duty and feel ashamed about the same.
Last night after having checked-out from the hotel in Singasandra, Bengaluru, I was on a cab towards Yevantpur station to board my train back to Chennai.
A few km after we left the hotel on the road, there was an accident scene. A motorist hit and run by some vehicle.
People surrounded, watching and gazing as to how the fellow-human being is gonna pass-away. I could hardly make out the age of the victim, but I could see the nerves from his hands and body throwing his entire body from the ground to a li’l above seeking help.
I asked the cab driver if he could call the ambulance or do something, who in turn responded, “Sir, these things happen quite normal every day. so nothing to worry, someone will take care of him”.
I was shocked on one hand but felt more shameful on the other hand that I felt so helpless in the situation. I couldn’t walk out of my comfort zone to hop off the carand help him too, as I was on the rush to the train station to board the train.
The car had to take a detour (basically a long u-turn after a mile and a half), whilst still, I looked-out thro’ the window to see if the victim sought some help, but couldn’t make out what happened.
If only there was civic sense, that poor victim of the accident would have immediately been taken by medical services.

I am now in Elkridge, Maryland, USA. I received this mail 9 days ago and I have reproduced it here after relieving it of certain personal messages. Here it is:
Dear Uncle Raj,
Greetings from Joe.
At the outset, let me convey the fact that I miss you all. There has never been a day or moment that I felt away from my family when I was there with you all.
I’ve tried to have face time with you all to see and talk to you folks, but haven’t been much successful. It’s either the internet connection or my pre-occupation with things that need be taken care over here.
How”s Aunty doing?…. you both make a great pair and have always been a great role model for us all. I’ll wait to receive you both in Chennai. Please share with Aunty that I’m reminded of her “Achaar” and let her know that Grills and Kababs are waiting for her in Chennai.
Uncle, Chennai’s heat wasn’t a piece of cake for me. The amount of pollution and dust and especially the nasty foul pungent odour which I sailed thro‘ in Chennai Central railway station to board Shatabdi to Bengaluru … People are still the same.
Spitting, shitting and littering all around.
No traffic sense, no civic sense, no respect for a fellow human.
I’m getting boiled going thro‘ all these, however, I’m trying to turn my ears a li’l deaf and my eyes a li’l blind to keep myself off from all these.
I’m unable to read your articles these days, coz scarce internet connectivity. I have an Airtel 3G data card with which I’m writing this email while on the train to Bengaluru.
