Equipping The Aquifers

The cities of modern India, the concrete jungles, are on the brink of severe water crisis. One city is competing with another as to which will dry up first.

A recent National Geophysical Research Institute (NGRI) finding states that the ground water in cities like Hyderabad, Chennai, Delhi and Mumbai along with several other cities of North India is declining at a rapid pace.

The graph accompanying the report shows that most of the cities in the north of India, in a short span of next 3 years would have no ground water beneath.

The report goes on to state,

“History shows that civilizations have vanished once water is gone. Water carries people and we need to do something before it is too late.”

This alarming situation has been primarily created because the cities have become concrete jungles. The channels to the local aquifers through which the rain water seeped in, have all been sealed. They have become places for public utility, thus depriving the land below the cities of their water. Consequently, the ground water that comes up through bore wells has got high levels of chloride and nitrates which in excess are harmful to our health.

What is the way out?

We have to first become alive to the situation, recognize that we have a problem on hand and act constructively before it is too late.

First what is an aquifer?

Underneath the hard rock on the surface of the earth, are layers of different types of rock. Some layers such as sandstone, conglomerate, fractured limestone, unconsolidated sand and gravel, basalt etc. have some amount of porosity and therefore allow water to seep and flow through them. Each type of rock allows the water to flow faster or slower depending on the size of its pores.

Water seeps in and exists within each rocky layer. Depending on the pattern in which these rocky layers are formed in the earth, water chooses to flow faster or slower in certain paths.

Thus if we can see through the rocks, we will see a slowly moving water body. This body of rock through which water is moving, is called an aquifer.

Slide1

An aquifer should not be mistaken for an underground river. An underground river is one that has a clear cut channel for water to move under the ground. Water does not have to seep through the rocks to move. It flows freely in the channel. It is just that the channel is buried and not seen from above ground.

Since in an aquifer, the water travels through tiny pores of the rocks, the water that comes out of an aquifer is usually clean.

Aquifers have natural recharge zones where water enters the rocky layer and they have a natural discharge zone where the water comes out of the rocks and collects as a pool or well. In between, man can intervene and drill into these rocks and tap into the aquifers. These are the bore wells of today.

It is because of these aquifers and plenty of recharge zones which allowed rain water to seep in, that we had wells, springs and tanks overflowing with water right through the year in India, across all seasons, even in times of failed monsoon.

In present times the situation is quite different.

  • Aquifer recharge zones have been blocked with unmindful construction.

  • Aquifer discharge zones have also been blocked with unmindful construction.

  • Aquifers have been tapped into indiscriminately with powerful bore wells.

  • Aquifers are being drained at a rate faster than that at which they are getting recharged.

  • Aquifer recharge zones are contaminated with chemicals and bacteria which enter the acquifer.

As a result, aquifers which are the main source of clean, ground water have all dried up and the result is water shortage everywhere.

Much of this is happening in cities since there are more people trying to live off the limited number of aquifers under the city.

When we construct any building, the first thing we need to do is build a foundation which goes to a depth that is calculated in proportion to the height of the building we want to construct.

Then why is it that when we come to cities, we do not make such fundamental calculations to build and populate in a regulated manner?

We think that a building is supported only by the concrete foundation below. We fail to think of the amount of ground water that will be available to support all the inhabitants of the building once it is completed.

Today’s buildings stand much beyond what their foundations can support – not the concrete ones but the rocky aquifers. The height of buildings in cities has far exceeded the depth of the aquifers available. The cities have literally sucked all the water out of the aquifers. To keep life in the cities going, water from aquifers in nearby areas too have been extracted and supplied to the cities.

The red zone in the graph is the most densely populated region of India as well as the world. No wonder we are seeing the graph as published by the NGRI.

Can our aquifers give us water once again?

Let us first look at what our ancestors had followed.

We may laugh at them for revering water as Punya Theertha, holy water. But they were wise enough to build percolation tanks for every small area of inhabitation. Typically these were built near temples and at outskirts of the village alongside slopes to catch the rainwater. These percolation tanks kept the aquifers recharged. The collection of water from these aquifers was also from natural wells, springs etc. which ensure that only as much as the aquifer could discharge was collected. They did not indiscriminately use powerful motors to suck up the waters from the aquifer faster than it could accumulate.

All this also meant that the population of any settlement was automatically regulated so that there was no undue burden on the aquifer and natural water resources.

Z To A

People are usually in the habit of using a phrase “A to Z”. But here we will talk about “Z to A”. Lets see what it means.

We have water harnessing practices which are local to the topography and climate of the region, across the length and breadth of India.

The water harnessing system in Ladakh in the North, is called the Zing, where they collect the waters as the snow melts, and channelize them for their agriculture and residential needs.

Kutch in the west, has its own system called Vradha.

It is Apatani in Arunachal Pradesh in the east.

In South India, it is the Eri, large tanks, Oorani, the smaller ponds and Annaicut, which are the water diversionary bunds.

In this land, through the years, the people have devised their own water harnessing practices from Zing in Ladakh to Annaicut of Kanyakumari, i.e. from Z to A. The people of this land have thereby harnessed the water for their prosperity through the ages.

Uniform observation

The observations of Megasthenes in 320 BCE , by Al Beruni in 1030 BCE and later by Sir Arthur Cotton show that the land as a whole was prosperous across ages because it employed sustainable water harnessing techniques generation after generation, to harness the monsoon waters  and use it through the year for the prosperity of the society, of the civilization.

Equipping our Aquifers

There are hundreds of lakes and other water systems dotting this land. These lakes and tanks have existed since time immemorial, much before the cities engulfed them. These water bodies are situated where they are, considering the topography, the gradient of the land.

Within each city there are not just a few, but a few hundred water bodies which were maintained by our ancestors through the ages for their benefit during their times.

 For our benefit in our times, we need to take the lead from our noble ancestors and maintain our aquifers so that our cities do not dry up and remain as sustainable places of living for our children and grandchildren.

 What needs to be done as a self-interest, local effort, is to ensure that each of these tanks, lakes which find themselves in the midst of every burgeoning city, are properly freed up from blockages, cleaned up to receive and store rainwater and thus used as recharge zones for the aquifers, the purpose for which they originally came to be.

 Next is an introspection on how one can decongest cities or certain regions, to put lesser demand on the limited aquifers under a city.

It is the month of May, when we are all feeling the brunt of the lack of water in our ground water sources. It is the right time to act, to ready ourselves to start gathering the rain water when the monsoon starts in June/July so that we can equip our aquifers atleast for the coming year and years to come.

 Where there is a will there is a way – for water – for an aquifer.

 May our efforts bear fruit.

Water And Food

June to September are the months when South and South East Asia get their monsoon rains.

The word “monsoon” comes from the Arabic word, “Mawsin”, meaning weather, which is why we have the word “Mausam” in Hindi for weather.  Here, the weather turns to rainy season.

It is the rain that gives us Pushkaram, fertility which is why every temple tank is called as Pushkarni, that land which gives us fertility.

The purpose of this rain, the harnessing of these waters and creating fertility is to make food for humans, for animals, for plants and for the earth as a whole. For food, is the basic platform, annamaya kosha, on which life is built for all living beings. Different beings take to different foods based on availability, biological needs, suitability, taste and other such factors. Producing this food also needs water. Foods cannot be grown without enormous quantity of water. When we think of our needs of water, we think of only our daily ablutions and our drinking water needs.

We normally think of the few litres of water that we drink in a day. Have we ever thought how much water is required to make the fruit that is served in our plate?

Water Consumption

We hardly think of the quantum of water that is needed which goes behind food production. Infact over 80% of the water that is used on the surface of this earth is for agriculture and other type of food production. Only about 10% is needed for industry and the balance 10% is for domestic and other uses. Infact domestic usage is a very small quantity.

Water consumption

The average consumption of direct water per person, per day is 3 litres.

Food Consumption

To grow the amount of food that an average person consumes for lunch or dinner, 700 litres is required per meal. The chart here gives us the water needed to grow our food.

Water for food1

Here we see that the real consumption of water is in food production, agriculture. We see that for agriculture itself it is so much.

In the case of livestock, meat production, the need of water is manifolds times more because these animals also have to consume water, air, food for all their lives. At, the end of it, they offer only few kilos of meat.

Veg vs Non Veg

Daily average consumption of water by a vegetarian eater is 2500 litres where as for a non vegetarian eater is 8000 litres per day.

This insight into how much water is needed for a vegetarian meal as opposed to a non vegetarian meal clearly highlights to us as to which is more eco friendly.

With the world facing increasing water shortage that has come about due to the unsustainable practices of man rather than reduced rainfall, the only sustainable way of sharing the available limited quantum of water, the prudent option and a scientific one, is to be a vegetarian by choice.

That is the only way we can reduce our ecological footprint and leave the planet more sustainable for generations to come.

Consumerism to Conservation

Ecological footprint is what we use up, consume from our environment around us during our brief stay on this earth. It is the strain that we put forth on the resources of mother earth.

Ecological footprint

The generation next is talking about ecological footprint as the new buzz word but do their eating habits show their concern for the ecology?

For eating is what we do 3-4 times a day and that is by far the  largest foot print that we leave or rather erase from this earth.

If we and our generation next have to survive, then the planet has to survive this phase of consumerism. This can happen only with a mind shift from consumerism to conservation. Conservation of Foodprints, Conservation of Footprints; it is saving water, conserving water, minimal usage of water. Moving from non- vegetarianism to vegetarianism is one of the key ways that we can contribute to this effort, four times a day, every day of our lives.

Taxing Time – The Way forward?

Smoking

In the last couple of decades we have come to realize that smoking is injurious to health not just to the smoker’s health but as well as to friends colleagues and family around who have been termed as passive smokers. So, to reduce the habit of smoking, governments now levy additional tax on cigarettes and tobacco product to dissuade people from smoking, to make the environment cleaner and healthier.

Liquor

Consumption of liquor is also a problem the world over. Excess liquor not only damages the liver of a person but also their lives. It affects the family as a whole and causes other collateral damages like road accidents, improper behavior towards woman, being uncouth. Recognizing this, the governments the world over have started levying additional taxes on liquor to put liquor out of reach for many. There are states where there is prohibition on liquor consumption.

Non Vegetarian Food

Through this article and by a series of others by other writers, it is becoming more apparent that consumption of non vegetarian food is making our environment unsustainable. It is evident that non vegetarian food eaters consume more of the ecological resources and leave behind a larger footprint than their vegetarian fellow beings.

Recognizing the extra strain that non vegetarianism is placing on the environment, the next step that the government should do is to impose additional tax on non vegetarian food so that vegetarians don’t have to bear the folly of others.

The additional tax could well be used to rejuvenate the environment and restore it to a sustainable state. Also, it would educate and motivate people to migrate from non vegetarianism to vegetarianism to make this world , our home, a sustainable one in the long run.

Eat Right & Be Merry

After taxing times come celebrations. Celebrations invoke the image of Carnivals.

Carnivals

A Carnival is a festival where all enjoy with merriment. The very word “carnival” conjures up images of rides, pageants, colorful decorations, unending food and flowing liquor.

Let us step back and look at the context in which this word “carnival” came to be. Its origins could be “Carne Vale” or “Carne Levare” which means “the act of abstaining from consumption of meat”. The word “Carne” is the root for words such as “carnal” denoting flesh and “carnivorous” for meat eating animals.

Such a practice does exist in many societies of Europe during the annual Lent period, a period when meat is strictly abstained from.

The Merry Goes Round

From then, to now, Carnival has become a festival where meat consumption is very high. What an interesting turnaround? A 180 degree turn from “Carne Vale”, “abstaining from meat” to becoming “Carnivorous”!

This shift has occurred between the medieval period to present times.

Is it not time now for another 180 degrees shift from the present to the future? From Non vegetarianism to Vegetarianism?

A shift to celebrating, living without meat, for, life is a celebration – a sustained celebration if we know how to celebrate it responsibly.
