Water Shortage: Lack of Water Storage Facilities is the Real Problem

Apr 20, 2016


Every week the Central Water Commission (CWC) puts out the total volume of water that it has in 91 storage reservoirs all over the country. These reservoirs have a total storage capacity of around 157.8 billion cubic metres(BCM). This amounts to around 62% of the total storage capacity of 253.4 BCM in the country.

Hence, the data put out by CWC is a good representation of the total water stored in the reservoirs across the country. For the week ending April 13, 2016, the total amount of water stored in these reservoirs stood at 35.8 BCM. Given that the total storage capacity of these reservoirs is around 157.8 BCM, the total amount of water currently available amounts to around 23.3%. This is less than one-fourths of the total storage capacity.

How does the situation look if we were to compare it with the same time last year? As on April 16, 2015, the total amount of water in these 91 reservoirs had stood at 50.9 BCM. This amounted to around 33% of the total capacity of these reservoirs.

Further, the total amount of water currently available is around 70.3% of that was available last year. Hence, the situation has deteriorated since then. This can be explained by the fact that the country has had two bad monsoons.

In 2015, the monsoon rains had stood at 86% of the long period average (LPA). In 2014, the monsoon rains had stood at 88% of the long period average(LPA). Two bad monsoons have essentially ensured that the total amount of water available in the CWC reservoirs is currently very low.

The good news is that this time around the monsoon rains have been predicted to be at 106% of the long period average. Unless, the India Meteorological Department goes badly wrong, the monsoon rainfall is going to be much better than the previous two years. This should help building up the water levels in the CWC reservoirs.

But that is just the short-term solution. The per capita water availability in India has been falling over the years. The average per capita availability of water as per the 2001 census was 1816 cubic meters. This fell to 1545 cubic metres as per the 2011 census. The number must have fallen further by now.

In fact, data from World Bank suggests that in 2014, the renewable internal freshwater resources per capita in India stood at 1,116 cubic metres. This had stood at 1,226 cubic metres in 2007.

As the Economic Survey of 2015-2016 points out: "India has much lower levels of water per capita than Brazil, one of the world's leading agricultural countries. This constraint is exacerbated because, while Brazil and China use approximately 60 per cent of their renewable fresh water resources for agriculture, India uses a little over 90 per cent."

So what is the way out of this? The simple answer is creation of more water storage capacity to start with. As Akhilesh Tilotia of Kotak Institutional Equities and author of The Making of India writes in a recent research note titled Dam It: "India's consumption of water was estimated to be 1,030 BCM per year in 2010 and is expected to rise to 1,498 BCM by 2030E. The current consumption of water would hence be around 1,100 BCM (of which ~80% of the water is used for agriculture and rest is split between housing and industry). For a country that even in a failed monsoon gets 2,640 BCM of rain, servicing a requirement of 1,100 BCM should not ideally be a challenge - so what gives?"

Further, there are rains, other than the monsoon, and then parts of India get snow as well. This leads Tilotia to conclude that India "receives a precipitation of ~4,000 BCM of rains (and snow) every year."

So the consumption of water stands at 1100 BCM. Even a bad monsoon gets 2640 BCM of rain, so where does the real problem lie? As Tilotia writes: "It should be obvious that if the bulk of rains fall in a few months of the year, the only way to get water through the year is to bank it. There are two ways in which water can be banked: a natural process of water seeping underground which is then pulled out over the course of the year or by holding back the water in artificially created storage areas or dams. As we have noted above, India has the capacity to store only 253 BCM of water (or less than 10% of normal monsoon rains). It is no surprise that we annually find ourselves without water in summers!"

The point being that if India's water problem needs to be solved, then first and foremost we need to create more water storage capacity to start with.

Further, efficiency of water usage in agriculture also needs to improve. As the Economic Survey points out: "Although water is one of India's most scarce natural resources, India uses 2 to 4 times more water to produce a unit of major food crop than does China and Brazil (Hoekstra and Chapagain [2008]). Hence, it is imperative that the country focus on improving the efficiency of water use in agriculture."

 Modi 2016: An Agenda For Revival
 The Modi Report The landslide victory of 2014 handed Modi more than just a clear mandate...It handed him immense responsibility of a nation dreaming of great progress.

From the euphoria of Achche Din the mood in India has swung to cautious disappointment and now we are in 2016...

Who will answer the question how Modi can turn this ship around and get India back on track?

Vivek Kaul has the answer and he has put it all down, along with his deepest thoughts on the challenges India faces, in our latest special report titled - Modi 2016 - An Agenda For Revival.

This will start to happen once state governments price power for agriculture at the right price, instead of selling it cheap or giving it away free. As the Economic Survey points out: "It has long been recognized that a key factor undermining the efficient use of water is subsidies on power for agriculture that, apart from its benefits towards farmers, incentivises wasteful use of water and hasten the decline of water tables."

The solutions to the water problem are well known. The question is do the government(s) [state governments as well as the central government] have the political will and the necessary money to go ahead and implement them.

In India we have large number of primary schools, then secondary and colleges, both private and public. At present they depend on government supply done through different sources or their own tube/bore wells. The water requirement of these units are limited. we should develop storage tanks sufficient to hold yearly requirement of water for collecting rain water and reuse. This will reduce the strain on ground water and leads to increased efficiency of water utilization.

Vivek. I am an ardent reader of your diary. It is a sad truth that India lacks the political will to implement measures that will really benefit farmers.
I would like to read more about how can we create a distribution system and infrastructure,by which the farmer gets the benefit of price rise in commodities and crop produce, rather than traders.

The one who toils in the heat in farms gets only a fraction of income, while political Kings of APMCs are revving their Mercedes.

Please a column on this problem, it's cause and the solution.

This obviously common sense solution shouldve occured to many indians long ago. But basically we dont have will for self improvememnt.our youth prefer wasting time in bollywood movies celebrity worship cricket and lots of other unproductive activities.the goos one smigrate who cares. Bharat has to build massive water tanks underground if not on surface.overhead tanks lay corss country piplines li nking underground water diffiicent areas with excess water areas. For this special task force involve youth motivate them.gwt funds from the big shots it affects them also indirectly create awareness though has to be on war footing.all encompassive

After reading this article one realizes the real issues . I wonder if the ministry for water resources knows these things and takes corrective action to combat it. Sheer incompetency may be one of the issues plaguing this country.
I have always felt that free anything results in misuse and neglect. Even a nominal charge if levied will bring in a semblance of responsible usage. This is where the political will has failed.
When we do have such experts , what stops the power that be from appointing a Committee of experts - a la Neeti Aayog-and iron out a solution rather than continue to lament about the situation year after year.
Hope wisdom dawns on the concerned authorities to get into action mode.

When a whole lot of Per capita figures are deteriorating , the focus shifts always on to the numerator and never on the denominator ( the population in this case ) . Should not some policy move be made in this direction of controlling the population?? If the control is not implemented in time , at some stage India may have to enforce one child policy , as in china, with the same self defeating results. Can you shed some light on this line of thinking ( controlling population )

The Graph relating to per capita availability of water is confusing. You remarked that India's per capita availability of water is less than Brazil. But if you see the Graph, the India's position (represented by red line) is better than Brazil (represented by green line) by 2010. Am I missing something here?
