INDIA: Diseases Follow Environmental DegradationArchna Devrajhttp://www.ipsnews.net/news.asp?idnews=35695 CHERTHALA,

Kerala, Dec 4 (IPS) - Lulled by social indices that compare with the

developed world's and tourist brochures that gush over ¡God's Own

Country', the deaths of 125 people from an outbreak of the

mosquito-borne disease, chikungunya, has come as a reality check for

people in this southern state.

Authorities and experts, starting with federal health

minister Anbumani Ramadoss, were quick to point out that the outbreak,

which raged through September and October, was linked to insanitary

conditions fostered by creeping environmental degradation in Kerala,

known for its lush, spice-growing hills, riverine valleys and serene

backwaters that empty into the Arabian sea.

Nowhere did the epidemic strike harder than in the state's prime

tourist destination of Alappuzha district, whose population of two

million people suddenly found suddenly itself at the mercy of aedes

aegypti mosquito and the virus it carried.

As tens of thousands of people went down with fever, joint pains,

nausea and diarrhoea, the typical symptoms, the state health delivery

system found itself overwhelmed. By Oct. 12, officials had admitted

that at least 125 deaths were attributable to chikungunya, with the

majority of casualties reported from Alappuzha's sub-district of

Cherthala.

For Kerala, this was a first encounter with chikungunya. Touring

Cherthala, Ramadoss, a medical doctor, admitted that the outbreak had

caught health officials unawares, but added that no hospital in the

country was equipped to respond to an epidemic outbreak of this nature.

 

It was left to a team of federal experts, and representatives of the

World Health Organisation, the National Institute of Communicable

Diseases (NICD) and the Vector Control Research Bureau to prescribe

remedial measures, a key component being the re-introduction of natural

predators of the mosquito.

Apparently, a decline in traditional agriculture, combined

with a rise in industries related to the export of marine and coir

products had upset the delicate ecology of the backwaters and turned

Cherthala into a vast cesspool of industrial and other effluents.

"It is not surprising that chikungunya has hit Cherthala. The pollution

level in the canals is very high. In fact, a report of the State

Pollution Control Board in 2002-03 had described Aroor in Cherthala as

the most polluted ¡panchayat' (village) in the state. Similarly, the

Chandiroor canal flowing through the area had been described as the

most contaminated,'' says journalist C Radhakrishnan, who lives in

Cherthala, and was among the first to report the chikungunya outbreak.

There were more recent warnings. The renowned Santhigiri

Siddha and Ayurveda Vaidyasala (SSAV), which is at the forefront of

reviving and popularising traditional healthcare systems of India had,

in a medical survey conducted in August, reported that the water

sources in Cherthala had become severely contaminated with industrial

waste and sewage.

"People do not have safe and wholesome water to drink.

Stagnation of contaminated water in the premises of each house is a

good medium for the multiplication of infective organisms and breed

mosquitoes,'' the survey warned.

The SSAV, a unit of Santhigiri Ashram, a charitable

non-government organisation, had adopted Chandiroor village in

Cherthala for a three-year medical programme aimed at making it disease

free, noted a rise in the incidence of filariasis (another

mosquito-borne malady), respiratory problems, skin disorders and

thyroid dysfunction.

According to the local residents, nearly 100 big and small

marine products exporting units dot the northern parts of Cherthala.

The waste from the processing units and the peeling sheds is dumped

into the canals leading to a choking of the water flow.

"Foul smell and slimy water are the bane of this area. Yet,

the authorities have shut their eyes to the problem. The local people,

being poor, have also not been able to organise themselves to raise

their voice against this menace,'' said Radhakrishnan.

More contamination comes from the 1,000-odd coir industries.

Every other house in the area is involved in producing coir from

coconut husk. The husks are kept underwater for months for retting, a

rotting process which exposes the fibre that is used in making ropes

and mattresses. "The large amounts of husks that lie rotting deplete

the oxygen in the water,'' says Dr V. Rajamani Amma, course coordinator

for an undergraduate programme on Environment and Water Management at

the local Nair Service Society college.

''The dye used to colour the coir also finds its way into the water.

Studies carried out a few years ago found a disturbingly high incidence

of cancer in the area,'' says Rajamani.

While the government accepted the findings of the report, precious

little was done by way of follow-up action said Rajamani, who is also a

University Grants Commission project researcher specialising in water

pollution. Pollution, she says, is ''rampant in water bodies all over

Cherthala. As the underground water runs merely three feet below the

surface, the contamination has spread to underground reservoirs, which

are the main source of drinking water''.

The high level of organic, chemical and sanitary waste has led to a

marked decrease in the oxygen levels, which in turn resulted has in the

extermination of fish and toads, natural predators which keep

mosquitoes under control.

According to local residents, an early indication of the increasing

contamination of the waterways was the large number of dead fish found

floating in the nearby Vembanad lake, a few years ago. This was a

direct consequence of the contamination of the lake water by the coir

and other industrial units situated close to it, they alleged.

However, no action was taken to clean up the canals, which are

linked to the Vembanad lake. ''If it were fish which died first, now it

is human beings. We are all paying the price for the increasing

pollution levels in this area,'' says Radhakrishnan.

Local farmers have another explanation for the rising levels of

mosquito infestation. A steady decline in the prices of the paddy

produced locally had resulted in most of the farmers giving up rice

cultivation, they say.

''The earlier farming activity kept mosquito breeding under

check. Farmers used to regularly clean the vacant plots and also

periodically clean up the ponds in the area. There was thus no scope

for mosquitoes to breed. Now, with the ponds and the vacant lots lying

unused, they provide an ideal breeding ground for mosquitoes,'' says T.

Gopalan, who gave up farming his paddy fields, unable to match cheaper

imports.

The State Pollution Control Board which has come in for flak from

locals for not doing enough to check the rising pollution levels in

Cherthala, claims that it has not been sitting idle. Board chairman G.

Rajamohan admits that ''a lot remains to be done..'' Recently the Board

issued closure notices to the polluting fish processing units in

Cherthala. ''We have given them three months time to clean up their act

or face closure.''

As for the coir units, Rajamohan said the Board will shortly introduce

new technology, developed by the Coir Board, the apex body for the

development of the coir sector in India, to avoid the oxygen-depleting

'retting' process.

Rajamohan said the problem of dyes leaching into the water was

already being tackled by treatment plants set up by the larger

export-oriented units, while the smaller ones are being encouraged to

go in for common effluent treatment plants.

Coir Board chairman A. C. Jose says that the completion of the

Rs 560 million (12.5 million US dollars) centrally-aided Alappuzha Coir

Cluster Development Project complete with common effluent treatment

facilities is expected to help reduce pollution levels in Cherthala.
