Landmark IPCC Report

Global Warming Likely to Continue

By Dhurjati Mukherjee

The UN Inter-governmental Panel on Climate Change (IPCC), a 2500-member strong group of scientists, in its fourth report issued in Paris recently, has presented overwhelming scientific consensus on greenhouse gas emissions and put the onus on these human-induced gases since the Industrial Revolution. In the past, climate scientists had made strides in pinpointing useful information and generating powerful computer models. In the new report prepared by scientists from 113 countries, researchers have gone one step ahead in using nearly two dozen models to produce projections of temperature and sea-level rises, all anchored with multiple lines of scientific evidence.

“Warning of the climate system is unequivocal as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global mean sea level”, the report said. As expected, most of the increase in global averaged temperatures since the mid 20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations. That is an advance since the Third Assessment Report’s conclusion that “most of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations”.  Discernible human influences now extend top other aspects of climate, including ocean warming, continental-average temperatures, temperature extremes and wind patterns.

Continued greenhouse gas emissions at or above current rates would cause further warming and induce many changes in the global climate system during the 21st century that would very likely be larger than those observed during the 20th century. It is indeed significant to note that global temperatures are predicted to rise by 1.1 to 6.40C with a rise of 40C most likely by the year 2100, which would have disastrous consequences for the human race.

At Continental, regional and ocean basin scales, numerous long-term changes in climate have been observed. These include changes in Arctic temperatures and ice, widespread changes in precipitation amounts, ocean salinity, wind patterns and aspects of extreme weather, including droughts, heavy precipitation, heat waves and the intensity of tropical cyclones. Indian scientists, who were part of the IPCC exercise, said that most computer-based models predict an increase in monsoon rainfall when the rise in only atmospheric carbon dioxide is taken into account. 

The obvious effects may be summarized as follows: loss of food production with global levels expected to fall by 10 per cent while African crops slumping between 15 and 35 per cent; increased flooding with sea levels rising up to 59 cm. and Bangladesh and Vietnam to be the worst hit countries along with coastal cities such as London, New York, Tokyo, Hong Kong, Kolkata and Karachi; upward trend is very likely in hot extremes and heat waves will continue; melting ice of West Antarctica and Greenland; more diseases exposing 80 million additional people; 25 to 50 per cent land species threatened with extinction; and water shortages affecting southern Africa and the Mediterranean severely. 

In fact, the situation today has reached a critical stage. It has been clearly stated in the report that even if concentrations could be held at the current levels, the effects of global warming would continue for centuries because it takes very long to remove the gases from the atmosphere. There is need to seriously ponder what needs to be done at this juncture as it goes without saying that eliminating the threat of global warming would require radical action.

The report has pointed out that a concerted action could stave off the direct consequences of global warming such as widespread flooding, drought and extreme weather conditions. Stabilizing atmospheric levels of carbon dioxide, the primary contributor to global warming, would require reducing carbon dioxide emissions by 70 to 80 per cent. Such a reduction would bring equilibrium with the planner’s natural ability to absorb carbon dioxide. It may be worthwhile to recall here that the last time the planet was in balance was more than 150 years ago before the widespread use of coal and steam engines. 

Scrapping all fossil fuel powered electricity plants worldwide and replacing them with wind mills, solar panels and nuclear power plants would make a serious dent in the problem but the question remains whether this will become possible in the immediate future. Compounding the problem is the fast pace of industrial development that has been taking place in the Third World countries, especially in China and India.

The impact of climate change on food production has been an area of great concern. The effect of high temperatures may affect India’s rice production. Temperature is a major determinant of crop development and growth and studies reveal that rice yields would dip by 10 per cent for each degree increase in minimum temperature during the growing season. Climatologists expect that global mean air temperature may go up between 1.4 to 5.8 0C by the end of the century, depending on changes in greenhouse gas concentrations.

With rapid population growth, rice production in the country has to be enhanced to about 122 million tonnes by the year 2020 to meet the increasing demand. But scientific studies presented at a recent conference of the International Rice Research Institute (in October 2006) have contended that the results of climate change impact may adversely affect rice yields not just in Northwest India but all over the country.

Even an impact assessment of climate change carried out on behalf of the Indian Council for Agricultural Research (ICAR) indicated that though in the short-term, rice production may not be affected significantly; in the long-term climate change would have serious impacts. In another study on Northwest India by the ICAR, researchers pegged the range of yield reduction from the technological determined level from 7 per cent in 2020 to 25 per cent in 2080.  

The Executive Director of the UN Environment Programme, Achim Steiner, stated and very rightly: “Anyone who would continue to risk inaction on the basis of the evidence presented will one day in the history books be considered irresponsible”. Another report by the Panel is expected later this year that would address the most effective measures for slowing global warming.

The Kyoto Protocol has so far been the main plan for capping greenhouse gases until 2012 but it has been severely weakened since the US pulled out in 2001. Though talks are under way for its post-2012 commitments, the participation on America and China is an urgent necessity. By some estimates, today’s emissions must be reduced by half globally by 2050 to peg the temperature rise by 2100 to 20 C compared with post-industrial levels. However, at this juncture scientists the world over would eagerly await the measures, preferably country-specific and time bound, that are expected to be announced by the IPCC to control the pace of climate change and reduce global warming to the extent humanly possible.---INFA

Growing Drug Addiction:Holi Hola Party: Oh Boy is this India? by Dr. Syed Ali Mujtaba, 17 March 07 Print E-mail

Growing Drug Addiction

Holi Hola Party: Oh Boy is this India?

By Dr. Syed Ali Mujtaba

The news flashed on the front pages of the major dailies on Monday, March 5, about the arrest of some 280 Holi party revellers at a Farm House on the outskirts of Pune city for drug abuse is an eye-opener to many Indians accustomed to reading about starvation deaths, farmer suicides, and female feticides in their newspapers.   

The revelations though a freak incident, undoubtedly point at three significant societal changes taking place in our country. One, India is moving on the path of high-end economic model. Two, drug abuse and alcoholism is on the rise among the youth. Three, certain sections of the youth, especially the yuppie crowd, is looking for promiscuous life style.

All these things come out glaringly if we recap the happenings at the rave party on the Sunday night. The participants had contacted the organizers through a website, www.isratrance.com that  was promoting the event from February 27.  They had received invitations via SMS, e-mails and through Orkut chat, paying hefty sums through credit cards. Some of them travelled from far off places like Kolkatta, Chennai, Bangalore and Ahmedabad to attend the party.

Allegedly organized by suspected international drug peddlers from Pune and Mumbai, the party had the guests served some 3000 `California drops, an acid that is put on a stamp and chewed. Each drop costs between Rs. 350 and 500. The party peaked at about 2 a.m and the crowd was in high spirits dancing to high voltage music, when a team of 100 policemen in plain clothes swooped on the venue and rounded up the revellers on charges of drug abuse and other crimes.

This was the first incident of such a high number of persons rounded up for such offences in the country. Those arrested were mostly youth aged between 22 and 30, including 29 girls. There were ten foreigners---three Africans, three Palestinians; two each from Germany and Iran. The girls ranged from students to air hostesses to Naval officers' daughters.

The items recovered from the spot included 2.5 kg of marijuana (ganja), 100 grams of hashish (charas), seven bottles of phenylfine hydrochloride, 15 crates of beer, 17 cheelams, cigarettes and condoms, all valued around Rs. 5 lakh. The police also seized a Dolby Music System, 45 four wheelers and 29 two-wheelers from the venue.

The big picture about the Sunday’s party is that too much money is going into the hands of a very small section of our people. This symptom has been evident since the liberalization of our economy some 15 years ago. The trickle down impact of the economy that was much touted really has not taken place. Instead, a small section of people has cornered a large portion of our wealth and resources. The kith and kin of such neuve riches are loaded with money and they look for spending opportunities. Such rave parties to them are tempting propositions no matter what these may cost.

The second noticeable trend is the mushrooming of IT offices, BPOs, and call centres in urban India. These places mostly thrive on outsourcing of jobs from abroad and provide tremendous opportunities for the urban youth. Young persons working in such offices are taking home hefty pay packets. With little expenses to bear, they have plenty of money to spare. Such people look for non-traditional source of entertainment. The rave parties are one hell of a place to spend the money and satiate one’s various desires. 

Such parties are also in demand for breaking the boredom of the insipid jobs that these flashy call centres, BPOs and IT offices offer. The jobs get on the nerves of the youth that are stuck there in the lure of big money. Many are forced to work for long hours and some even find themselves reduced to being slaves of their key boards and the monitor screens. Such persons, at the first opportunity, want to break their monotony and look for outings to unwind themselves.

The other fall out of the high-end economy is growing drug addiction among certain sections of the youth. Recently, we had the high profile case of Rahul Mahajan, son of the BJP’s late leader Promod Mahajan, who had to battle for his life after taking drugs. The incident took place at a private party in his home where his father's secretary lost his life due to overdose of the drugs.

The Sunday Holi party confirms that Rahul Mahajan’s case was not an isolated event to be brushed under the carpet. Such parties for drug consumption are regularly taking place in some urban centres among select circles of friends without anyone knowing about it.

The other offshoot of the high-end economy is that youth is increasingly getting attracted towards alcoholism. It is common to see youth these days revelling in the company of friends with alcohol and drugs. Come any festival, Diwali, Dusherra, Holi or New Year, such activities are fashionable among the urban youths. 

The high-end economy is also triggering promiscuity among sexes, particularly among the neuve riches. Recently, there was the high profile case of teenagers making pornographic video through the cell phone camera and sending it on the SMS to their circles of friends. This, in turn, made rounds of many handsets in the country and even hogged the limelight of the media. The public was shocked and asked: “Oh Boy is this India?”

In the mad and reckless race to catch up with the West, the things that are least admirable are being aped by our young generation. The movies, the TV serials, the pictures on the dailies and the tabloids are all pushing the youth towards  promiscuity.

Even though the Holi party was a freak incident of some adventurous people caught off guard seeking fun, it certainly hints at the societal changes taking place in our country. It is also indication of the fact that Indian values that hold high moral ground are losing their sheen due to the onslaught of the Western influences. This underlined the need to cultivate the right family values among our young so that when they become adult they don’t go wayward like the Holi Hola revellers at Pune.---INFA

Power Generation Target:TOWARDS PROMOTING SOLAR ENERGY, by Radhakrishna Rao,10 March 2007 Print E-mail

Power Generation Target

TOWARDS PROMOTING SOLAR ENERGY

By  Radhakrishna Rao

Though India has an enormous renewable energy potential, the current installed capacity of around 8100-MW derived from renewable energy sources including sun, wind and biomass constitute abut 7% of the total installed power generation capacity in the country, even though India is one of the pioneers in utilizing a part of its huge reserve of renewable energy sources.

Against this backdrop, India’s Ministry of Non-Conventional Energy Sources has set an objective of achieving an installed power generation capacity of 10,000 MW from renewable energy sources by 2012.  Of course, the non-polluting and abundantly available solar energy constitutes an important component of the strategy aimed at boosting the popularity of renewable energy sources in India, which are considered both cost effective, local specific and non-polluting.

Meanwhile, the Ministry has decided to install 10- million metres of solar collectors during the Eleventh Plan period. As it is, the Plan would involve installing solar heaters in about 3.5 million individual houses in the country. In addition, industrial units and commercial establishments spread across the country would also be covered under the solar energy popularization programme.

As envisaged now, this ambitious programme, when implemented in full, is expected to result in peak saving about 5,000 MW in addition to abatement of 7.5 million tonnes of highly polluting carbon di oxide emissions annually.

Union Minister for Non-Conventional Energy Sources, Vilas Muttemwar points out that the availability of solar energy for upto 300 days a year in various parts of India is a major positive factor for going ahead with the popularization of solar energy devices in the country. He drives home the point that India has a total potential for generating about 200,000 MW energy from non-conventional energy sources.

Meanwhile, there is growing conviction that inexpensive and flexible solar cells could help avert the looming energy crisis haunting the humanity. For right at the moment, the technology for designing and developing solar energy gadgets continues to be far from economically viable and as such the current thrust is on refining and upgrading the technology to the level at which it would be possible to develop inexpensive solar cells.

For decades, solar cell researchers have tried to develop cheaper alternatives to silicon. For instance the US-based Konark Technologies has come out with a technology appropriate for developing inexpensive and easy to carry solar energy devices. Konark plans to join hands with the multi-national Siemens for taking some critical steps towards changing how we think about harvesting energy from the sun who has been glorified in the Hindu spiritual literature as a “powerhouse of inexhaustible energy”.

Interestingly, a couple of years ago, Indian President Dr. A.P.J. Abdul Kalam became the first global citizen to get two refrigerator-cum-vaccine coolers, totally powered by the sun. This solar chill uses a breakthrough technology aimed at making the process of refrigeration accessible even to the remotest parts of the world and hence help several social causes such as vaccination projects for polio eradication.

This device was developed by Rajendra Shinde who as the head of the Ozone Action Unit of the Nairobi-based United Nations Environment Programme (UNEP) was keen on engineering a solar power driven chilling device with a view to reduce the emission of green house gases responsible for global warming. In fact, the idea of developing such an innovative cooling system struck him during a bus ride in the poverty stricken African country of Burkina Faso in 2000.

Looking out of the bus window at the children of the rural poor and thinking about their fragile health, it occurred to me that the plenty of sunshine does not mean plenty of health. I thought that if we could develop vaccine cooler that uses solar energy abundantly available there, it will be an environmentally perfect product” quipped Shinde.

All said and done, the energy efficiency of the currently available solar photovoltaic system which convert sun light into electricity is rather low at around 7-17%. If the efficiency of the solar photovoltaic could be pushed up further, it could lead to a drastic fall in the cost of energy generation.  As such efforts are on to use materials like thin films and gallium arsenide in place of silicon for solar energy devices.

Of course, some experimental solar photo voltaic cells now convert nearly 40% of the solar energy into electricity. The cost of production is quite high due to the high price of silicon crystals. Of course, research efforts are underway for engineering new and cost effective fabrication techniques. In India state owned Bharat Heavy Electricals Ltd (BHEL) and Central Electronics Ltd. (CEL) are in the forefront of engineering and producing devices meant for exploiting the solar energy.

As it is, the solar photovoltaic power system developed by BHEL have been pressed into service in various locations of India---from 30 KWP supply to data collection platform at Leh in Jammu and Kashmir to 10 KWP hybrid power plant at Lakshadweep island in the Arabian sea to photovoltaic system for offshore platforms and for railway signaling panel interlocking and microwave repeater stations.

A recent success story of the BHEL’s solar energy system was in Mousuni island in West Bengal where the country’s largest solar power plant is in operation. Designed, manufactured and commissioned by BHEL, the 105 KWP plant has changed in many ways the lives of the islander who had for long been deprived of the benefits of electricity. This solar energy plant caters to individual houses, schools, street lights and waterpumps.

Interestingly, the BHEL has also supplied space grade solar cells for the satellites designed and developed by the Indian Space Research Organisation (ISRO) The Bangalore-based TATA BP Solar is a major player in the solar water heater systems.

Meanwhile, the New Delhi-based The Energy and Resources Institute (TERI) has warned that if India fails to speed up and augment the use of renewable energy sources, India’s import of costly and highly polluting fossil fuels would continue as usual. “The country needs to undertake all possible options on the demand and supply side simultaneously to reduce total energy requirements as well as diversity its fuel resources mix”, says the TERI study. ---INFA

Coal Vision-2025:CENTRAL PLAN TO BOOST PRODUCTION, Dhurjati Mukherjee,3 March 2007 Print E-mail

       Coal Vision-2025

CENTRAL PLAN TO BOOST PRODUCTION

By Dhurjati Mukherjee

The coal sector is destined to receive lot of attention in the coming years and Coal India Ltd. (CIL) would invest Rs. 15,600 crores to increase production to 521 million from the present 363 million during the Eleventh Plan period (2007-12). An additional Rs. 8,000 crores would also be invested under the Coal Vision-2025 for coal beneficiation up to 2025 while the investment during the Eleventh Plan would also be quite substantial, according to Dasari Narayan Rao, Union Minister of State for Coal.

In the Integrated Energy Policy, the demand projection made for coal for the year 2031-32 was about 2500 million tonnes as against the expected demand of 473 million tonnes during 2006-07. The Government has decided to increase production from underground mines and the production target has been increased to 75 million tonnes by 2011-12 (from the earlier projection 54 million tonnes) through induction of latest technology and collaborative ventures. Moreover, coal production from captive mines would also increase from 15 million tonnes to 105 million tonnes during the Eleventh Plan.

The demand for washed coal has inspired CIL to set up washeries under the Build & Operate (B&O) concept where private companies with core competence in state-of-the-art coal washing would be encouraged to set up such units. Only washed coal would be supplied to various categories of consumers other than the pithead power plants. A time frame and a detailed plan in this regard would be formulated by CIL. 

As is well known, India ranks third amongst the coal-producing countries of the world. Through a sustained programme of investment and greater thrust on application of modern technologies, it has been possible to raise production of coal from a mere 70 million tonnes at the time of nationalization in the early 70s to over 400 million tonnes presently. Most of the coal produced in India comes from open-pit mines, contributing over 80 per cent of the total production.

It is a well-known fact the country has rich coal reserves and extensive exploration carried out by the Geological Survey of India and other agencies down to a depth of 1200m have estimated 245.69 billion tonnes of coal resources. The coal resources are available in sedimentary rocks of older Gondwana formations of peninsular India and younger tertiary formations of the Northern/North-Eastern hilly region. The States with high coal resources (including proved, indicated and inferred) are Jharkhand, Orissa and Chattisgarh.  

With increasing trend towards industrialization, power requirement has gone up considerably and is likely to increase further in the coming years. Coal is obviously the most important source of energy though in recent times alternatives are being explored. About 70 per cent of coal is consumed in the power sector and the rest in industries such as steel, cement, fertilizers paper etc.

In the transport sector, however, direct consumption of coal by Railways is going down on account of phasing out of steam locomotives. To cope with the increasing demand for coal, there is an imperative need to gear up production and productivity.

The present demand of 445 million tonnes of coal per annum is expected to go up to 1260 million tonnes by 2025. And the Government is poised to take necessary steps to increase coal production to meet the demands in steel, power and cement industries with an expected increase of 150 million tonnes per annum.

It is a well known fact that coal will continue to be the leader in meeting the energy needs of the country and obviously is the focus of attention as the power sector has been growing at the rate of 5 per cent per year. To keep up this momentum, the Coal India has been stressing the need for adoption of modern technology, as open cast reserves may not last for more than 50-60 years.

According to CIL sources, the following areas of research are being given major thrust for advancement of technology: CBM resource assessment and recovery techniques suitable for Indian conditions, including technology for commercial utilization; underground coal and lignite gasification of deposits, which are not techno-economically amenable to conventional mining methods; hard roof management for underground mines by establishing technologies like hydro-fracturing or safe blasting with explosives or non-explosive materials; trials of suitable mining methods for sleep and thick seams; detection and mapping of old and unapproachable workings; wireless multimedia communication for underground mines; and dry beneficiation of coal and improvement in fine coal recovery techniques.

Apart from this, modern IT tools as also R&D efforts to achieve technology adoption, adaptation and assimilation, particularly to suit Indian conditions, and achieve process efficiency and consistency are also being implemented. In tune with the Vision Statement-2020, prepared by the Union Ministry of Mines, already some positive developments have taken place, but safer and more conformable automation of increasing number of tasks and application of computer technology would become necessary in the foreseeable future.  

Technological innovations in the mining industry, and especially in the coal sector is indeed vital for achieving the production growth and meeting the demands of the country. At the first Asian Mining Congress held in 2005, the efficacy of longwall mining and its success in major coal producing countries like China, USA, Australia and South Africa made experts acclaim this technology. In a remarkable presentation, the authors (Dr S.K. Sarkar and Prof. A. K. Ghosh) had rightly pointed out that in spite of the failure of longwall mining in India, the ground realities have changed over time and this would be the preferred option in many locales.

Mention may be made of factors such as locales being at high depth where open casting is not possible and any variant of bord and pillar mining is not feasible, steady rise in labour rates over the years and lack of interaction between foreign agencies instrumental in executing the longwall programme and Indian scientific institutes. However, recently the Longwall Powered Supports have been introduced in a limited scale 

At such a juncture, many developing countries like China, India, Mongolia and Iran who greatly benefited from technological innovations in the mining industry have the potential to further surge ahead in the coming years through tie-ups with the advanced countries and also among themselves.

As regards coal is concerned, the Government has expressed its intention for 100 per cent foreign direct investment in the sector to meet the increasing needs. Moreover, experts are also examining the existing bottlenecks and obstacles to tap resources to advanced technological means, which are vital for increasing coal output.

India is endowed with rich mineral deposits but the pace of industrial growth has necessitated development of modern mining technology to explore more yields of iron ore, bauxite, copper and chromites apart from coal and lignite. It is expected that sustained research would yield better results, leading to higher production and productivity of coal, so as to keep pace with the projected 9 per cent growth this year.---INFA

Global Warming Worries:Dimension Of Water Crisis,Radhakrishna Rao,24 February 2007 Print E-mail

Global Warming Worries

Dimension Of Water Crisis

By Radhakrishna Rao

A recent report of the Inter-Governmental Panel on Climate Change (IPCC) points out the possibility of progressively declining rainfall and fast depleting snow in the mountain ranges by 2030.  India is worried that the water crisis arising out of the global warming could adversely affect the food yield in the country.  According to researchers, a two degree increase in surface air temperature would mean a fall in yields between 4% and 34% by mid-21st century.

The well-documented report highlights the fact that small land holders and subsistence farmers are likely to suffer complex, localized impact of climate change. In the ultimate analysis crops like sorghum and millet could be at the greatest risk, both from drop in productivity and loss in crop genetic diversity.

As experts point out, agriculture irrigation demand in arid and-semi arid regions of Asia is expected to increase by 10% for a temperature increase by one degree centigrade.  Whether the affected countries could be able to meet the growing demand for water for the farm sector, none is sure as yet.

Meanwhile, a recent report compiled by the Stockholm-based International Water Management Institute (IWMI) states that the growing demand for irrigation to produce food and bio-fuels is likely to aggravate scarcity of water. “One in three people is enduring one form or another form of water scarcity” says IWMI.  Going ahead the report observed, “conquering hunger and coping with an estimated 3-billion extra people by 2050 will result in about 80% increase in water use for agriculture on rain-fed and irrigated land”.

Interestingly, water resources management expertise opine that solutions for such a problem include helping poor countries in Africa and Asia to grow more food with available fresh water via simple, low cost measures in a shift from past policies that favoured expensive dams or canals. Prof. C.H. Hanumantha Rao, a well-known agriculture economist drives home the point that there is an immediate need to regulate water usage by involving local communities in the water management. He advocated immediate, stringent measures to conserve water in order to avoid a major water crisis in the future.

According to Food and Agriculture Organisation (FAO), progress in meeting the water needs of the world in the years ahead would depend on a shift from what the FAO calls, “a culture of supply management”. Says the FAO: “While the specific objective is to provide a more reliable and adequate water supply for crops, proper management of water resources will always have significant impact on economic activities, environmental processes and people’s health”. 

Indeed, the FAO stresses that the environmental concerns must be a part of the modernization in water use and management. Clearly and apparently, extraction from rivers and the construction of irrigation infrastructure invariably displaces natural wetlands, which are highly productive components of agro-ecological systems.

Abundant and sustained availability of fresh water is vital for industrial and economic growth, as well as for the well-being of the community. However, uneven distribution of water resources due to a combination of climatic and geological factors makes for water deficient and water surplus areas within a country.  Indeed, as water resources experts point out, transfer of water from surplus zones to deficit zones in an environmentally-sustainable and economically-viable manner holds the key to ending the cycle of droughts and famines haunting many parts of the country with recurring regularity.

Studies carried out by various agencies show that in the past 35 years, water table has come down to as much as 30-60 metres in several parts of India.  In particular, the green revolution Punjab has witnessed the decline in water table by around 30 metres on account of the sinking of around a million tubewells. At this rate, the Washington-based think tank, World Health Institute warns that underground aquifers in India could go dry by 2025.

On the other hand, in the coastal State of Gujarat, sea water incursion and increase in salinity level in several areas have made water unfit for human consumption. Indeed, studies by the IWMI point out that a large part of the western and peninsular India is all set to face a serious water crisis in the coming 25 years. According to the IWMI studies, marginal and small farmers operate only 15% of India’s total farmland but are saddled with 73% of the abandoned tube wells due to lower water tables and higher energy costs.

As it is, ground water continues to support more than half of the country’s irrigated farmland. Inefficient use of irrigated water leads to low water productivity even in crops that have higher water use efficiency.  Sunita Narain, Director of the New Delhi-based Centre for Science and Environment (CSE) advocates water harvesting as an important tool to manage water scarcity. The thesis of the World Bank is that tubewells play an important role in preventing social conflicts and political upheavals over water in India.

A study by John Briscose, a water resources expert with the World Bank, observes that urbanization and changing patterns of cropping are putting severe pressure on the fast declining ground water table in the country. He is of the view that investment in water infrastructure will provide some respite to the excessive exploitation of the ground water resources.

The water usage trend, Briscose said, suggests that while irrigation from underground aquifers has gone up, canal irrigation has not made much headway. The future, he observes, will also witness major transformation in the way public water services are provided to the farmers, households and industries.  Briscose also points out that issues concerning water entitlement, financial sustainability, accounts and regulation will assume importance in the days ahead.

Clearly and apparently, the World Bank report forecasts that India might face a turbulent future in so far as water availability is concerned.  Unless drastic changes are made and made soon, the way in which the Government manages water, India will have neither the cash to maintain and build a new infrastructure nor the water required for the economy and the people” says the World Bank study. The study highlights in a very clear cut manner that failure of India to build sufficient water storage capacity will prove to be undoing of the country.

While the rich countries have built over 5000 cubic metres per capita storage capacity, the middle income countries like Mexico and China have a per capita capacity to store 100 cubic metres of water. In contrast, the Indian water storage capacity per capita is at a low of 200 cubic metres. As such the World Bank argues that the role of the State must change from that of a builder and controller to the creator of enabling environment for the water supply system. ---INFA
