Managing e-waste without harming environment (April Week 1 (2006))
e-Parisara recycles old computers, other e-waste
· Bangalore generates 8,000 to 10,000 tonnes of e-waste a year
· e-waste is partly recycled, the left over is burnt or thrown away
· e-Parisara functions from an industrial estate in Dobbspet
· It has equipment to recycle up to three tonnes of waste a day
As the information technology hub of the region, Bangalore generates thousands of tonnes of electronic waste.
To this can be added almost an equal quantity of imported electronic scrap and computer parts. They are partly recycled, and
what is left is burned or thrown away causing pollution and health hazards.
A pilot project to manage e-waste without causing ecological damage has been set up close to the city by P. Parthasarathy, a
postgraduate from IIT-Madras and now a Bangalore-based entrepreneur.
e-Parisara functions from an industrial estate in Dobbspet, about 40 km from here, and has been encouraged by the Central
and State Pollution Control Boards who would like it replicated in all major cities in the country.
This initiative, the first of its kind, attempts to carefully recycle old computers, their components and other e-waste,
generated by both IT companies and electronic manufacturers into social and economically useful raw material than can be
The technology used is indigenous, according to Mr. Parthasarathy.
At e-Parisara the more hazardous components such as chromium, arsenic, mercury, nickel, cadmium, lead and zinc sulphate are
separated from the material they are contained in. Plastic and glass waste is sold to recyclers authorised by the Karnataka
State Pollutuion Control Board.
The metal content that can be safely reused is separated and the rest carefully buried without contaminating the soil or
e-Parisara has equipment to recycle up to three tonnes of waste a day, but is dealing with around one tonne right now. Many
corporates such as IBM, Tate Elxsi, ABB and Phillips are among its clients. But many major IT firms are yet to send their
e-waste or stipulate difficult conditions, Mr. Parthasarathy said.
According to industry surveys, 8,000 to 10,000 tonnes of e-waste is generated each year by IT firms and electronics
manufacturers in and around Bangalore.
While the larger companies have warehouses for storing the waste, others sell them to small-time scrap dealers.
The dealers, many concentrated around Mysore Road, often employ women and children to deal with the scrap and remove usable
What cannot be used at all is thrown into fields and channels or burned under unsafe conditions. Apart affecting the health
of the employees of the scrap dealers, air, soil and ground water get polluted.
The e-Parisara example may be one workable solution.

All about wetland birds (April Week 1 (2006))
A two-day workshop on `Wetland Birds', organised by the Kozhikode-based Malabar Natural History Society (MNHS) here on April
1 and 2, gave an opportunity to bird lovers to get an overview of the diversity and census methods adopted by ornithologists
to monitor their population, breeding patterns and the like.
Through slide shows, the participants learnt about varied aspects relating to wetland birds of Kerala. Though the State does
not have large wetlands, there are diverse species of water birds in the State, including ducks, terns, herons and egrets,
besides migratory species.
C. Sashikumar spoke about the techniques and tips on conducting a bird census. Details of recording the vast species of
water birds of Kerala, identification methods, the ideal season for conducting census, and the like were highlighted.
Satyan Meppayur spoke on `Cormorants, egrets, herons and ducks', while Mohammed Jaffer Pallot's slide show was on `Gulls and
terns'. Babu Kambrath dealt with `Photographing wetland birds' and O. Jayarajan on `Wetland Bird census — an overview.'
The participants were taken on a field trip to the Kadalundi Bird Sanctuary on Sunday.
Forest Minister A. Sujanapal, who inaugurated the workshop, emphasised on the need for a specific environment policy. "Just
as there is an IT Mission, there should be an Environment Mission too so that bureaucratic red-tape can be a avoided. He
said creating awareness about the environment through organisations such as MNHS, and people-participatory movements was
vital to preserve natural resources.
The environmentalist John C. Jacob delivered the keynote address.
A book `Mammals of Kerala' authored by Dineshan Cheruvat, C. Radhakrishnan and Mohammed Jaffer Pallot was released by Mr.Sujanapal.

Vacate prod to save wetlands (April Week 1 (2006))
Waking up to the threat posed to the East Calcutta Wetlands by several realty projects, the Buddhadeb Bhattacharjee
government has finally decided to initiate action against the offenders.
The process of clearing up the 12,500-hectare sprawl and restoring it to its original form has begun, with the first step
being relocation of the proposed Dhapa water pumping station of the Calcutta Municipal Corporation (CMC).
The government is also drawing up a list of buildings on the wetlands, declared a “no-development” zone by Calcutta High
Court. The owners will be asked to vacate and the structures will be demolished.
Prodded by chief secretary Amit Kiran Deb, the CMC has agreed to shift the proposed 30-million-gallon water pumping station
from the periphery of the wetlands.
“We have chosen another site that is a km away, on Calcutta-Basanti Road. There is no risk of filling up any waterbody
there. We have approached the East Calcutta Wetlands Authority for clearance,” civic commissioner Alapan Bandyopadhyay said
“The CMC project was to have come up on 20 acres off the wetlands. We have relocated it. As for other violators, we’ll not
allow them to encroach on the wetlands, which is a Ramsar site,” asserted chief secretary Deb, who also chairs the
The panel is compiling a list of unauthorised structures that have come up on the watery sprawl over the past two decades.
“We’re especially concerned about the structures that have come up after 2002, since these violate the Ramsar norms,” Deb
An environment department official said a survey had identified 700 constructions that have come up after the site won the
Ramsar tag in 2002.
As many as 4,500 settlements have come since 1992, the year Justice Umesh Chandra Banerjee of the high court declared the
area a wastewater recycling region.
According to officials, the owners of the post-2002 structures will be issued eviction notices after the Assembly elections.
“Most of the violators are first-time offenders. If they fail to relocate within the specified time, the structures will be
demolished,” a member of the wetlands authority said.
With the Wetland Management Authority coming into being, the right to grant clearances for all projects in the area rests
solely with it.
“From now, project promoters will have to first approach the Authority, which will forward the proposal to the department
concerned for its perusal,” said an official.
“There is no need for separate clearances from the fisheries department, land and land reforms department and the state
pollution board, as the Wetlands Authority is the single window for issuing the final okay,” the official added.

Navaratra night halt in Gir Sanctuary? (Issue of the week, March Week 3 (2006))
Wildlife activists in Gujarat have sought Prime Minister Manmohan Singh's intervention to withdraw permission given to pilgrims to stay overnight at Kankai temple, located in the Gir forest, during the nine-day Navratri festival beginning March 30.
In a letter to Singh, a copy of which was marked to President Abdul Kalam and UPA chairperson Sonia Gandhi, Gir Nature Club chairman Amit Jethwa and other activists have stated that the concerned forest staff had illegally granted permission to the pilgrims
to enter the Gir sanctuary and national park during Navratri without any timing restrictions.
However, conservator of forest Bharat Pathak, says, "We would be permitting entry of pilgrims as per rules. There has been no relaxation during Navratri.
Also, except for the trustees and the temple priest, no one would be permitted to stay in the temple at night." The activists, however, question the building of rooms near the temple for night halts.
Jethwa says Navratri is celebrated twice a year in Kankai. He claims as per rules, pilgrims are allowed to enter the sanctuary from sunrise to sunset. He claims that such ‘illegal' permission would prove to be disastrous for wildlife.
In the letter, the environmentalists also state that Gujarat High Court has banned stay and entry in Gir after sunset. But the temple authorities have compelled the government of Gujarat to cancel the entry fee and this has increased the flow of visitors.
He alleged that over one lakh visitors are expected to stay in the sanctuary during the nine-day festival. The activists have stated that Gir is the only and last home of the Asiatic lion. Kankai is situated in the protected area.
Manish Vaidya, chairman of Ahmedabad-based nature club Sabar, said the temple authorities have started creating a concrete jungle. The authorities have also made arrangements for night halt in the temple premises, which disturbs the wildlife.

River-link cloud on monsoon ‘engine’ (March Week 3 (2006))
Interlinking India’s rivers on a massive scale might raise salt concentration in the Bay of Bengal and tinker with the “engine” that drives the monsoon, atmospheric and environmental scientists have said.
Freshwater from the Ganga, Brahmaputra and the Mahanadi flowing into the Bay of Bengal plays a critical role in intensifying monsoon activity by maintaining low salt levels in the layer of water in the top 20 metres of the bay.
Canals between rivers might reduce freshwater discharge into the bay, raise salinity (salt level) and affect monsoon rainfall, said Vedharaman Rajamani, professor at the school of environmental sciences at Jawaharlal Nehru University.
“The low salinity in the Bay of Bengal sustains convection, which is the engine for the monsoon,” Rajamani said. The low salinity leads to relatively higher temperatures at the sea surface, which stimulates convection and cloud formation. Increased salinity
would mean lower sea surface temperatures and lower potential for cloud formation, which might mean less rain.
“We can’t say with 100 per cent certainty that this will happen. Nor can we say it won’t happen,” he said. “Physics tells us some impact is likely. We need to simulate in computer models how river links will change rainfall.”
Since the 1960s, successive governments have been evaluating proposals for connecting rivers through a complex network of canals that would transfer water across river basins and reduce the flow of river water into the sea.
The ministry of water resources has been engaged in preparing feasibility reports on proposed links between several rivers — Mahanadi-Godavari, Ganga-Gandak and Ganga-Damodar, among more than a dozen others. Last year, Uttar Pradesh and Madhya Pradesh signed
an agreement for preparation of a detailed project report on the Ken-Betwa link.
Scientists, however, caution that not enough is known about the monsoon to predict its behaviour under reduced freshwater flow into the Bay of Bengal.
“Less freshwater discharge could indeed increase salt concentration and lower temperature. But to assume that this will also reduce the rainfall is a huge jump with a hypothesis,” said Debasis Sengupta, an atmospheric scientist at the Indian Institute of Science
Sengupta said “common-sense physics” does suggest that the lower the sea surface temperature, the lower the convection and the lower potential for clouds and rain.
“However, the region with the deepest and most persistent cloud is not always the region with the highest sea surface temperatures, he added. “In a system as complex as the monsoon, common sense may not apply.”

Farmers turning to organic farming (March Week 3 (2006))
In recent years human health has been affected by chemically contaminated food items, hence developed countries have started encouraging organic farming.
Today organic agricultural products market exceeds 35 million dollars. In our country also many NGOs and progressive farmers have taken up organic farming and have registered a profit of Rs 71.23 crore during last year through export. Organic farming is being
taken up in 38,000 hectares. As people are becoming more health conscious, the demand for chemical-free organic products is increasing. Organic produce fetch higher prices than chemically grown products.
More than 7,000 members have registered in Organic Agriculture Producers Co-operative Association. The organic market will be developed in Bangalore’s JP Nagar and Indira Nagar and government has allocated RS 2.5 crore.
In north India many NGOs are providing training on organic farming to farmers. In Rajasthan Morarka foundation a NGO has created a revolution as more than 10,000 farmers have taken up organic farming.
In Shekavathi district alone, more than a thousand farmers have registered with Morarka foundation, and in Badavasi village of Junjhunu district, it is mainly the women who have taken up organic farming.
Vasanth, an organic farmer from Bangalore, had made a trench to prevent chemicals from entering into his land from nearby farms during rain. He said he is getting good returns despite deep price fall of agri-products. He said Bangalore-based ‘Phalada Foundation’
is helping farmers to interact with foreign buyers from European countries including the Netherlands.
Many foreign buyers have visited Vasanth’s estate. He said that organic turmeric is helpful for digestion, blood circulation and has disease resistance power.
It is also being used to treat cancer. He said he produces organic manure by farm wastes. He has also prepared pesticide out of 32 herbs and panchagavya. He said by using this he has controlled many pests. He said he has planned to make turmeric powder packets
and to sell it locally.
For more details about organic farming call Vasanth on 944822028.
