Too much sugarcane
The editorial 'Rivers of discord' (DTE, Vol 11, No 11; October 31, 2002) was very interesting. I liked the way kuruvai and sambha crops were explained, so even a reader who knew nothing about it to begin with would understand the situation. The solution suggested for optimum utilisation of water is also fascinating. The suggestions on growing less water-consuming crops and diversification in cropping pattern in the lower reaches of Cauvery command were particularly commendable.
I would, however, like to stress that any solution for optimum utilisation of water in agriculture must necessarily include discouragement of sugarcane farming, or at least a significant reduction in the area utilised for growing sugarcane. Sugarcane has become a popular crop, and is grown by the politically powerful, as indicated in your editorial. Sugarcane is a perennial crop and, therefore, consumes more water during its growth. Its water requirement is more than that of most other crops. Keeping this in view, the area suggested for sugarcane crop in the cropping pattern of a proposed irrigation project should not be more than 15-20 per cent, except in fields specifically devoted to sugarcane.
The leader 'Power 'em' is also well-written. Speaking from my experience of visiting various rural areas in India -- in Orissa, Bihar, Rajasthan, Kerala, Tamil Nadu, Karnataka, West Bengal, Madhya Pradesh and Uttar Pradesh -- I fully endorse the view on empowering people. I say this especially with regard to farmers and villagers, who are the real backbone of the Indian economy. However, the administration should set out on this task prepared with the knowledge that there could be tremendous hurdles on the way.

Crisis management
I refer to the special report 'Shut and dried' by Binayak Das (DTE, Vol 11, No 8; September 15, 2002). dte has rightly targeted the serious issue of privatisation of water and the economics behind it. Since the issue of privatisation is at present confined to some individuals in the field of water management, the working of this system needs to be clearly explained. This will enable everyone to understand it better. The article is highly commendable in this regard. More so in the face of the reality that privatisation of water distribution is unavoidable in the near future.
In this context, I also stress on the importance of treatment of sewage water. This could make enormous quantities of recycled water available for our domestic needs. In fact, 90 per cent of the water supplied by the local administration is misused for non-drinking purposes. Such water is then quickly disposed as sewage water. If this water is treated and recycled, the problem of water scarcity could be solved to a large extent.

Two news items in dte (Vol 11, No 11; October 31, 2002) caught my attention: both on water. When I was in Singapore recently, I came to know about a dispute between Malaysia, the supplier of drinking water, and Singapore, the consumer. Half the requirements of water in Singapore are met with imports from Malaysia. Hence the tension.
The use of recycled water is a welcome step towards reducing dependence on imports of water. Conservation and recycling are the answers to water conservation, whether in India or elsewhere.
The decision by industries in Bangalore to use recycled water is good news. With each failing monsoon, drought-like conditions are forcing people to conserve water and harvest rainwater when the rain god smiles. The worth of water can be seen only in times of acute shortage. The time has come to see water as a valuable natural resource that may be in short supply, and is certainly not going to be cheap or free. The emphasis should be on using available water with care and not waste it.

Healthy alternatives
Plastic is one of the major threats to our environment. The most prominent contributors to this menace are plastic carry bags, disposable cups and plates, packaging material used to pack chocolates and store cool drinks. These cannot be recycled more than once. Moreover, the process of recycling these toxic substances is terribly dangerous to the people handling it.
Plastic carry bags are mostly used for carrying fruits and vegetables. Using cloth bags can quite easily cut this down. Vendors often try to display their generosity by offering plastic carry bags to reluctant customers. People resort to these as they are convenient.
These days, most ceremonies or public functions also use plastic cups and plates. One understands that these articles are convenient and easily disposed. However, a possible alternative would be plates and cups made out of natural materials, like the outer skin of the arecanut tree and dried banana leaves. These small acts of concern can bring about considerable transition in our filthy urban environs.
One should also avoid drinks that are fashionably packed in plastic containers. Tea, coffee and tender coconut are healthy and clean substitutes. By doing this we are also discouraging multinational companies. Packaged food and chocolates are equally dangerous, as they need a lot of plastic for packaging. Indigenous and nutritious foods would be the most appropriate substitutes. Foods like mudde (ragi ball) and uppsaru (a simple curry that retains nutrition) have the additional advantage of guarding us from ill-health.
I hope my fellow citizens will consider this humble plea and avoid using plastics.

Quick note
We received this response to a query from I M Prabhu Kumar of Bharat Earth Movers Limited (DTE, Vol 11, No 10; October 15, 2002), asking readers for suggestions on an environmentally healthy manner of discharging coolants.
If you discharge coolants in the fields, you contravene the hazardous waste management rules under the Environment Protection Act, 1986. The rules stipulate that these must be issued to authorised recyclers of pollution control boards and the ministry of environment and forests. One such agency in Karnataka is Sri Durga Chemicals Corporation, and you may contact them for disposal on a regular basis. The address is given below:
Administration office
99/5, Laxman Rao lane,
B V K Iyengar Road Cross
Bangalore - 560 053
Phone: 080-2872421, 2871755, 2875716, 2383482
Mobile: 98451 79512
As regards your concern about smell and bacterial growth inside the coolant, an effective method of preventing this is to introduce a small amount of air inside the coolant, either through compressed air (which is expensive) or through a blower, whenever you go on shutdown like weekends. The bubbles will prevent bacteria formation.
In Lucas-TVS, we have also initiated an action for reconditioning the coolant. This increases the life of the coolant three times, i.e. if we are discharging once a month now, we could discharge once in three months. This reduces the effluent by one-third, and coolant oil consumption by 70 per cent.
Compact equipment, with filters (for cleaning the coolant) and ultraviolet lamps (for removing bacteria) are available. The equipment is not expensive, and is easy to handle. We had carried out trials with this equipment and are satisfied with its performance. One such unit is already functioning in Bharat Heavy Electricals Limited, Trichy, for the past two years and they say that its performance is very satisfactory. I give below the address of a supplier of such equipment:

This is with reference to the quick note by Mr. P.S. Srinivasan, Vice-president, Projects and environmental management representative, Lucas-TVS, Chennai, Tamilnadu, in your magazine issue dated November 30, 2002. We thank him for giving us a good feedback on our product "Emulsion Coolant Recovery Systems". Our system removes the contaminants like tramp oil, suspended solids and bacteria from coolants making it completely re-usable. We are available online at www.ncsassociates.com. Click on "Products -> Emulsion Coolant Recovery Systems". The product page has a presentation on our system and a FAQ section, which answers all queries regarding our system. We hope that this information is useful to engineering industries that are facing this problem and we would like to help them in recycling coolants and reducing costs by upto 85%.
