The Pallikaranai Wetland in Chennai: Part 2 – Now It Is a Concrete Jungle!

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.

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.

.

There is an incredible rate of development in the Pallikaranai wetland. The sanctioning of many IT parks has resulted in countless high-rise office and residential buildings.

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.

In 2007, to protect the remaining wetland from shrinking further, 317 hectares of the marsh were declared by notification as a reserve forest by the State of Tamilnadu.

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.

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.

Why am I interested in wetlands and writing about them?

Because 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 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.

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.

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:

GROUP NUMBER OF SPECIES
Birds 115
Plants 114
Fishes 46
Reptiles 21
Mammals 10
Amphibians 10
Molluscs 9
Butterflies 7
Crustaceans 5
Total 337

Birds, fishes and reptiles are the most prominent of the faunal groups.

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.

The Five Days of December 1952 When the Killer Smog Blanketed London.


.
Myself 

By T.V. Antony Raj

The modern fight against environmental pollution around the world owes much to the tragedy that befell Greater London, about 63 years ago. The haphazard use of coal brought the country to the brink of a frightening black disaster on December 5, 1952.

During the Industrial Revolution, from about 1760 to around 1840, there was a transition to new manufacturing processes. The main factor in this transition was the change from wood and other biofuels to coal.

Indiscriminate use of coal drove Britain, the most powerful empire in the world. Tall smokestacks became the symbols of the industrial age in Britain. The appalling use of coal in industries, for generating electricity, heating homes, for cooking, etc., was frightening. Trains, boats, iron, steel, everyday items used coal. In London, it was like millions of micro-volcanoes erupting all at once. It was as if London was eating coal to survive.

People were burning large quantities of poor quality coal and emitting pollution at low elevations. The pollution from home chimneys was double the amount of the industries.

In the Victorian era, London was well known for its romantic fog that covered the city for 90 days each year for decades. But as the years passed by, this romantic fog and the smoke and fog turned into a poisonous cloud of smog (smoky fog) during each winter. In his book “Reminiscences of Sherlock Holmes” Sir Arthur Conan Doyle (18591930) wrote:

In the third week of November, in the year 1895, a dense yellow fog settled down upon London. From the Monday to the Thursday I doubt whether it was ever possible from our windows in Baker Street to see the loom of the opposite houses. … But when, for the fourth time, after pushing back our chairs from breakfast we saw the greasy, heavy brown swirl still drifting past us and condensing in oily drops upon the windowpanes, my comrade’s impatient and active nature could endure this drab existence no longer. He paced restlessly about our sitting- room in a fever of suppressed energy, biting his nails, tapping the furniture, and chafing against inaction.

Construction of the first phase, the A Station of the Battersea Power Station, began in March 1929. It first generated electricity in 1933, but was not completed until 1935. The total cost of its construction was £2,141,550. It burned approximately 10,000 tons of coal each week to supply one fifth of the electricity for the entire city of London.

Slowly, with time, London became completely covered in soot.

In late 1952 an unusual cold cinch had gripped London for weeks. On December 5, 1952, the day the disaster began, Londoners awoke to find a clear sky, but coal fireplaces worked overtime to fight the chill in the air. As the day progressed, a light veil of fog began to blanket the city. In the afternoon, the fog mixed with the thousands of tons of soot being pumped into the skies of London by million or more coal stoves, home chimneys, from local factories and industrial smokestacks began to turn a sickly shade of yellow and settled in the London basin.

Smog was nothing new for Londoners, but on that day, this thick sulfurous yellow “pea souper” quickly thickened into a poisonous brew, unlike anything the city had ever experienced before. A high-pressure system parked over London caused a temperature inversion. The air about a thousand feet above the surface, warmer than that at ground level kept the smog under the clouds and prevented it from rising. And, there was no breeze to disperse and dissipate the soot-laden soup.

For five days from Friday, December 5 to Tuesday, December 9, 1952, the Great Smog paralyzed life in London. Poisonous smog closed down all establishments.  Day became as dark as night.

People found it difficult to breathe the murky air. The smog was so dense that residents of the Isle of Dogs section of the city reported they were unable to see their feet as they walked. It was as if they needed a blind person to lead them home.

The dense smog crippled all transportation. Boat traffic on the Thames came to a halt. Bus conductors holding flashlights and torches walked in front of the double-deckers to guide drivers. Flights were grounded, and trains canceled. Only the Underground was in service.

.

The ambulance drivers had to rely on the police and people holding live burning torches s to show them the way.

London was completely silent. Only sirens of ambulances which brought those whose lives were in danger to the hospitals was heard. The ambulance drivers had to rely on the police and people holding live burning torches to show them the way.

Even at mid-noon, automobile drivers and motorcyclists turned on their headlights. They hung their heads out the windows in a futile attempt to inch ahead through the yellow gloom. Many abandoned their vehicles.

All weekend soccer matches were canceled. However, Oxford and Cambridge carried on with their annual cross-country competition at Wimbledon Common. As runners materialized out of the thick haze, the track marshals shouted continually, “This way, this way, Oxford and Cambridge.”

Since the smog seeped even inside closed buildings, movie theaters closed down as the yellow haze made it impossible for the audience to see the screen. The opera houses too put up their shutters as the audience could no longer see the performers on the stage due to the acrid smog.

The unparalleled admissions to hospitals and the great number of pneumonia reports overwhelmed the medical authorities.

Sadly, the Great Smog was not only a nuisance, it was also lethal for those with respiratory and cardiovascular problems, the elderly, the babies and the infants. Amidst coughing and the wheezing, death came silently to London. The smog literally choked thousands to death. Deaths from bronchitis and pneumonia increased more than seven-fold and the death rate in the East End increased ninefold.

Eventually, the siege abated on December 9, 1952, when cold winds from the west swept the toxic smog away from London and carried out to the North Sea. Yet, the detrimental effects lingered on, and death rates remained above normal into the summer.

Initial reports estimated that upwards of 4,000 died prematurely in the first week of the Great Smog. The mortality rate remained high for a couple of months after the Great Smog. People realized the impact of the deadly Smog when the undertakers ran out of caskets and the florists out of flowers and bouquets.

There were 12,000 unexplained deaths and additional deaths during the episode and in the two months after the abatement of the peak smog.

A preliminary report not finalized yet attributed these later deaths to an influenza epidemic. New evidence shows that only a fraction of the deaths could be from influenza.

.

The lungs of the dead confirmed that they died due to prolonged exposure to black carbon.
The lungs of the dead confirmed that they died due to prolonged exposure to black carbon.

.

Thorough examinations of the lungs of the dead confirmed that they died due to prolonged exposure to black carbon, a byproduct of burning coal and a short-term overexposure to a high concentration of fine particulate matter containing heavy metals.

Initially, the British government was reluctant to act in the wake of the Great Smog.

The Coalition for Clean Air calculated the concentration of pollution in London at the time. They concluded that it might have surpassed the current pollution in China by a large margin even though PM2.5 was not measured at the time. During the Great Smog, the concentration of sulfur dioxide was 190 times higher than the WHO standard.

Following the investigation, the British Parliament passed the Clean Air Act of 1956, which restricted the burning of coal in urban areas. The Act authorized local councils to set up smoke-free zones.

The public received grants to convert from coal stoves to alternative heating systems.

It took years, for London to transit from its primary source of heating coal to gas, oil, and electricity. During the transition period, deadly smogs occurred periodically, such as one that killed 750 people in 1962. But none of them reached the scale of the Great Smog that descended upon London on December 5, 1952.

In the 1960s, after the Great Smog in London, other countries began to reduce and control their use of coal.

Now, India, a country suffering from severe air pollution is also on a similar footing. Soon, India will become the world’s second largest consumer of coal. Yet, as of today, India has not yet set standards for emissions of important pollutants in its industries.

Fatu Kekula: the Brave Ebola Lifesaver


.
Myself . By T.V. Antony Raj

.

The rampant spreading of the Ebola Virus Disease (EVD) in Liberia, has created a chaos in that country. As on October 18, 2014, out of the 4,665 patients diagnosed for Ebola in Liberia, 2,705 died. In the past week alone Monrovia reported 305 new EVD cases. Out of the 15 counties in Liberia 14 have reported cases of Ebola. Only Grand Gedeh county has yet to report an EVD case.

Even before the outbreak of the Ebola virus, Liberia faced a health crisis. It had only 50 physicians in the entire country – one for every 70,000 citizens. In September 2014, the US Centers for Disease Control and Prevention (CDC) reported that some hospitals in Liberia had been abandoned, and the hospitals which were still functioning lacked basic facilities. They did not have running water, rubber gloves, and sanitizing supplies.

At the end of August 2014, the World Health Organization (WHO) stated that Liberia fell short of 1,550 beds to treat EVD patients. In September, a new 150-bed treatment clinic opened in the capital, Monrovia. At the time of the opening ceremony six ambulances were already waiting with potential Ebola patients. More patients were waiting by the clinic after making their way on foot with the help of relatives.

The treatment of EVD in other parts of the country is more pathetic. To add to the woes, on October 12, 2014, Liberian nurses threatened a strike over wages.

Amidst this chaos comes the story of Fatu Kekula, a brave 22-year-old Liberian nursing student.  She took care of four relatives affected by the Ebola virus by herself. She managed to save three out of the four patients, she cared for. That is a whopping 25% death rate, far better than the estimated average Ebola death rate of 58% in Liberia. Now, her unique methods for survival are being taught all over West Africa.

In July 2014, Fatu’s father, Moses Kekula, experienced high blood pressure. She took him to the local hospital in Kakata. After admitting Moses, the crowded hospital provided a bed that had become free. At that time, none of Fatu’s family members knew that the previous occupant of the bed had died from EVD. Soon after, Moses showed symptoms of EVD. He developed a fever. He started vomiting and had diarrhoea. A few days later the authorities shut down the hospital because nurses started dying of EVD.

Fatu then took her father to Monrovia. Three hospitals turned him away because they were already filled over capacity. So, Fatu took her father back to Kakata and got him admitted in another hospital. There they said he had typhoid fever and did little for him. Frustrated, Fatu returned home with her father.

At home Moses infected three other family members: his wife Victoria (57), elder daughter Vivian (28), and nephew Alfred Winnie (14). Fatu was the only unaffected family member.

Fatu contacted their family doctor. But he refused to come to their home, fearing the possibility of getting infected. Taking the next best option, Fatu requested the doctor to for directions. She got the medicines and fluids prescribed by the doctor from a local clinic. Her training at the nursing school helped her create her own intravenous lines.

Fatu then began to take care of her father, mother, sister, and cousin, all by herself. She put her three patients – father, mother and cousin in makeshift isolation ward in a spare unfinished room at home.

She did not have personal protection equipment such as those white space suits and goggles used in Ebola treatment units. She invented her own protective gear. She came up with the trash bag method. She took all the precautions for avoiding contact by using layers of trash bags on her feet and hair. She wore rubber boots, four pairs of gloves, and a face mask.

She fed her patients, gave them medicines, and cleaned them, all by herself day in and day out. It is a miracle that Fatu herself was not infected in the two weeks she was taking care of her family though she was in close contact with them.

On August 17, 2014, space became available at John F. Kennedy Medical Center, the national medical center of Liberia, located in the Sinkor district of Monrovia. Fatu’s father, mother, and sister recovered, but her cousin Alfred Winnie succumbed to the disease at the hospital the following day.

Fatu Kekula’s father is trying to find a scholarship for her that so she can finish her final year of nursing school. He has no doubt his daughter will go on to save more lives in the future.

Scientists allege deadly diseases such as Ebola and AIDS are bio weapons being tested on Africans. Other reports have linked the Ebola virus outbreak to an attempt to reduce Africa’s population. Liberia happens to be the continents’s fastest growing population.

The Liberian Daily Observer, a newspaper based in Monrovia, published an article on September 9, 2014 titled “Ebola, AIDS Manufactured By Western Pharmaceuticals, US DoD?

This controversial article was authored by Dr. Cyril E. Broderick, a Liberian-born former professor of Plant Pathology at the University of Liberia’s College of Agriculture plant pathology and Forestry. He was also the former Observer Farmer in the 1980s. In the late 1980s, Firestone spotted him and offered him the position of Director of Research. Dr. Cyril Broderick was for many years an Associate Professor at the College of Agriculture and Related Sciences of the University of Delaware.

Dr. Cyril E. Broderick points an accusing finger at the United States for the outbreak of Ebola. The sprawling haemorrhagic virus has killed close to 3,000 and infected close to 6,000 in West Africa since March this year. The countries seriously affected are Liberia, Sierra Leone, Guinea, Nigeria, DR Congo and Senegal.

He says Ebola, a genetically modified organism (GMO), is a biological weapon of mass destruction, just like AIDS. Ebola, he says, was created in collaboration with Western transnational pharmaceutical firms, secret military bio-warfare bases of the US Department of Defence (DoD), as well as some Universities. He accuses the United States for testing the virus using Africans as guinea pigs for secret human trials.

He also imputed that the UN and the WHO have been tacitly complicit in the testing of Ebola and other viruses on human guinea pigs in Africa.

Professor Broderick said that he decided to publish the article in response to various Internet reports that implied that the African people are gullible and ignorant.

Here is Broderick’s full unedited article.

Ebola, AIDS Manufactured By Western Pharmaceuticals, US DoD?

By Dr. Cyril Broderick, Professor of Plant Pathology

Dear World Citizens:

I have read a number of articles from your Internet outreach as well as articles from other sources about the casualties in Liberia and other West African countries about the human devastation caused by the Ebola virus. About a week ago, I read an article published in the Internet news summary publication of the Friends of Liberia that said that there was an agreement that the initiation of the Ebola outbreak in West Africa was due to the contact of a two-year old child with bats that had flown in from the Congo. That report made me disconcerted with the reporting about Ebola, and it stimulated a response to the “Friends of Liberia,” saying that African people are not ignorant and gullible, as is being implicated. A response from Dr. Verlon Stone said that the article was not theirs, and that “Friends of Liberia” was simply providing a service. He then asked if he could publish my letter in their Internet forum. I gave my permission, but I have not seen it published. Because of the widespread loss of life, fear, physiological trauma, and despair among Liberians and other West African citizens, it is incumbent that I make a contribution to the resolution of this devastating situation, which may continue to recur, if it is not properly and adequately confronted. I will address the situation in five (5) points:

1. EBOLA IS A GENETICALLY MODIFIED ORGANISM (GMO)

Horowitz (1998) was deliberate and unambiguous when he explained the threat of new diseases in his text, Emerging Viruses: AIDS and Ebola – Nature, Accident or Intentional. In his interview with Dr. Robert Strecker in Chapter 7, the discussion, in the early 1970s, made it obvious that the war was between countries that hosted the KGB and the CIA, and the ‘manufacture’ of ‘AIDS-Like Viruses’ was clearly directed at the other. In passing during the Interview, mention was made of Fort Detrick, “the Ebola Building,” and ‘a lot of problems with strange illnesses’ in “Frederick [Maryland].” By Chapter 12 in his text, he had confirmed the existence of an American Military-Medical-Industry that conducts biological weapons tests under the guise of administering vaccinations to control diseases and improve the health of “black Africans overseas.” The book is an excellent text, and all leaders plus anyone who has interest in science, health, people, and intrigue should study it. I am amazed that African leaders are making no acknowledgements or reference to these documents.

2. EBOLA HAS A TERRIBLE HISTORY, AND TESTING HAS BEEN SECRETLY TAKING PLACE IN AFRICA

I am now reading The Hot Zone, a novel, by Richard Preston (copyrighted 1989 and 1994); it is heart-rending. The prolific and prominent writer, Steven King, is quoted as saying that the book is “One of the most horrifying things I have ever read. What a remarkable piece of work.” As a New York Times bestseller, The Hot Zone is presented as “A terrifying true story.” Terrifying, yes, because the pathological description of what was found in animals killed by the Ebola virus is what the virus has been doing to citizens of Guinea, Sierra Leone and Liberia in its most recent outbreak: Ebola virus destroys peoples’ internal organs and the body deteriorates rapidly after death. It softens and the tissues turn into jelly, even if it is refrigerated to keep it cold. Spontaneous liquefaction is what happens to the body of people killed by the Ebola virus! The author noted in Point 1, Dr. Horowitz, chides The Hot Zone for writing to be politically correct; I understand because his book makes every effort to be very factual. The 1976 Ebola incident in Zaire, during President Mobutu Sese Seko, was the introduction of the GMO Ebola to Africa.

3. SITES AROUND AFRICA, AND IN WEST AFRICA, HAVE OVER THE YEARS BEEN SET UP FOR TESTING EMERGING DISEASES, ESPECIALLY EBOLA

The World Health Organization (WHO) and several other UN Agencies have been implicated in selecting and enticing African countries to participate in the testing events, promoting vaccinations, but pursuing various testing regiments. The August 2, 2014 article, West Africa: What are US Biological Warfare Researchers Doing in the Ebola Zone? by Jon Rappoport of Global Research pinpoints the problem that is facing African governments.

Obvious in this and other reports are, among others:

(a) The US Army Medical Research Institute of Infectious Diseases (USAMRIID), a well-known centre for bio-war research, located at Fort Detrick, Maryland;

(b) Tulane University, in New Orleans, USA, winner of research grants, including a grant of more than $7 million the National Institute of Health (NIH) to fund research with the Lassa viral hemorrhagic fever;

(c) the US Center for Disease Control (CDC);

(d) Doctors Without Borders (also known by its French name, Medicins Sans Frontiers);

(e) Tekmira, a Canadian pharmaceutical company;

(f) The UK’s GlaxoSmithKline; and

(g) the Kenema Government Hospital in Kenema, Sierra Leone.

Reports narrate stories of the US Department of Defense (DoD) funding Ebola trials on humans, trials which started just weeks before the Ebola outbreak in Guinea and Sierra Leone. The reports continue and state that the DoD gave a contract worth $140 million dollars to Tekmira, a Canadian pharmaceutical company, to conduct Ebola research. This research work involved injecting and infusing healthy humans with the deadly Ebola virus. Hence, the DoD is listed as a collaborator in a “First in Human” Ebola clinical trial (NCT02041715, which started in January 2014 shortly before an Ebola epidemic was declared in West Africa in March. Disturbingly, many reports also conclude that the US government has a viral fever bioterrorism research laboratory in Kenema, a town at the epicentre of the Ebola outbreak in West Africa. The only relevant positive and ethical olive-branch seen in all of my reading is that Theguardian.com reported, “The US government funding of Ebola trials on healthy humans comes amid warnings by top scientists in Harvard and Yale that such virus experiments risk triggering a worldwide pandemic.” That threat still persists.

4. THE NEED FOR LEGAL ACTION TO OBTAIN REDRESS FOR DAMAGES INCURRED DUE TO THE PERPETUATION OF INJUSTICE IN THE DEATH, INJURY AND TRAUMA IMPOSED ON LIBERIANS AND OTHER AFRICANS BY THE EBOLA AND OTHER DISEASE AGENTS.

The U. S., Canada, France, and the U. K. are all implicated in the detestable and devilish deeds that these Ebola tests are. There is the need to pursue criminal and civil redress for damages, and African countries and people should secure legal representation to seek damages from these countries, some corporations, and the United Nations. Evidence seems abundant against Tulane University, and suits should start there. Yoichi Shimatsu’s article, The Ebola Breakout Coincided with UN Vaccine Campaigns, as published on August 18, 2014, in the Liberty Beacon.

5. AFRICAN LEADERS AND AFRICAN COUNTRIES NEED TO TAKE THE LEAD IN DEFENDING BABIES, CHILDREN, AFRICAN WOMEN, AFRICAN MEN, AND THE ELDERLY. THESE CITIZENS DO NOT DESERVE TO BE USED AS GUINEA PIGS!

Africa must not relegate the Continent to become the locality for disposal and the deposition of hazardous chemicals, dangerous drugs, and chemical or biological agents of emerging diseases. There is urgent need for affirmative action in protecting the less affluent of poorer countries, especially African citizens, whose countries are not as scientifically and industrially endowed as the United States and most Western countries, sources of most viral or bacterial GMOs that are strategically designed as biological weapons. It is most disturbing that the U. S. Government has been operating a viral hemorrhagic fever bioterrorism research laboratory in Sierra Leone. Are there others? Wherever they exist, it is time to terminate them. If any other sites exist, it is advisable to follow the delayed but essential step: Sierra Leone closed the US bioweapons lab and stopped Tulane University for further testing.

The world must be alarmed. All Africans, Americans, Europeans, Middle Easterners, Asians, and people from every conclave on Earth should be astonished. African people, notably citizens more particularly of Liberia, Guinea and Sierra Leone are victimized and are dying every day. Listen to the people who distrust the hospitals, who cannot shake hands, hug their relatives and friends. Innocent people are dying, and they need our help. The countries are poor and cannot afford the whole lot of personal protection equipment (PPE) that the situation requires. The threat is real, and it is larger than a few African countries. The challenge is global, and we request assistance from everywhere, including China, Japan, Australia, India, Germany, Italy, and even kind-hearted people in the U.S., France, the U.K., Russia, Korea, Saudi Arabia, and anywhere else whose desire is to help. The situation is bleaker than we on the outside can imagine, and we must provide assistance however we can. To ensure a future that has less of this kind of drama, it is important that we now demand that our leaders and governments be honest, transparent, fair, and productively engaged. They must answer to the people. Please stand up to stop Ebola testing and the spread of this dastardly disease.

Thank you very much.

Sincerely,

Dr. Cyril E. Broderick, Sr.

The Pallikaranai Wetland: Part 2 – The Once Pristine Idyllic Wetland Is Now a Wasteland cum Concrete Jungle!

Why am I interested in wetlands? Because I am concerned. My home in Jalladianpet is just 2.5 miles (4 km) from the Pallikaranai wetland in Chennai, Tamilnadu, India.

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). It serves as nature’s primary aquifer recharge system for Chennai city. It harvests rain water and the flood water during monsoons and thereby mitigates the desolation and suffering that floods could cause in low-lying areas in Chennai.

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

At present 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 marshby Shaju John. This article was augmented by 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.

Continual inhaling of the ever-present malodorous germ and virus bound air, the stifling smoke, polluted and poisoned ground water subject the people living miles around the Pallikaranai wetland to major wheezing and carcinogenic health hazards.

.

.

The incredible rate of development, such as the rampant construction of sanctioned IT parks, the National Institute of Ocean Technology (NIOT) campus, Hospitals, Colleges, high-rise office and residential buildings, the Velachery MRTS railway station, the flyovers, the road connecting old Mahabhalipuram Road (OMR) and Pallavaram, etc., in the midst of the marshland also have immensely contributed to the shrinking of the water spread.

In 2007, to protect the remaining wetland from shrinking further, 317 hectares of the marsh were declared by notification as a reserve forest by the State of Tamilnadu.

Nevertheless, 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 Mahabhalipuram Road (OMR) and Pallavaram that bisects the marsh should also be declared a forest reserve.

However, even now, dumping of garbage by the Chennai metropolitan authorities goes on unabated.

The Pallikaranai Wetland: Part 1 – Flora and Fauna


.
Myself By T.V. Antony Raj
.

Why am I interested in wetlands? Because I am concerned. My home in Jalladianpet is just 2.5 miles (4 km) from the Pallikaranai wetland in Chennai, Tamilnadu, India.

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.”

The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation that adapts to its unique soil conditions. Primarily, wetlands consist of hydric soil, which supports aquatic plants

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.

The Pallikaranai Wetland

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 sq Km). It is the Chennai city’s natural primary aquifer recharge system.

The original expanse of the marsh, estimated on the basis of the Survey of India toposheets (1972) and CORONA aerial photographs (1965) was about 5,500 hectares, which has now been reduced to about 600 hectares. Situated next to the Bay of Bengal, about 12.5 miles (20 Km) south of the city centre, it is bounded by Velachery (north), Kovilambakkam (west), Okkiyam Thuraipakkam (east), and Medavakkam (south). It is the only surviving wetland ecosystem of the city and is among the few and last remaining natural wetlands of South India. It is one of the three in the state of Tamilnadu, the other two being Point Calimere and Kazhuveli.

The Pallikaranai wetland is one of the 94 identified wetlands in India under the National Wetland Conservation and Management Programme (NWCMP) of the Government of India that came into operation in 1985–86.

The terrain consists of fresh/saline water bodies, reed beds, mud flats and floating vegetation.

Flora and Fauna

This wetland is literally a treasury of bio-diversity that is almost four times that of Vedanthangal bird sanctuary in the Kancheepuram District of the state of Tamil Nadu, India, 47 miles (75 km) from Chennai where more than 40,000 birds (including 26 rare species), from various parts of the world visit during the migratory season every year.

The Pallikaranai wetland contains several rare and endangered species of plants and animals. It 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 wetland is definitely more than 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 wetland ecology.

In 2003, the Tamilnadu State Pollution Control Board assigned her 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:

GROUP NUMBER OF SPECIES
Birds 115
Plants 114
Fishes 46
Reptiles 21
Mammals 10
Amphibians 10
Molluscs 9
Butterflies 7
Crustaceans 5
Total 337

Birds, fishes and reptiles are the most prominent of the faunal groups.

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.

The Pallikaranai wetland is also home to some of the most endangered reptiles such as the Russell’s viper.

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.
