Main Causes of Present Water crisis in India
Rising demands of increasing population
Over extraction of easily available surface and Over extraction of easily available surface and groundwater resources
Increasing human impact on the environment and Increasing human impact on the environment and contamination of available water sources
Changing climate Changing climate
Excessive environmental degradation in catchment areas.
Pollution of river water, ground water
Gross mismanagement of the land and water resources : gdroughts, floods, landslides, etc
Blind following of unsustainable materialistic western life gstyles in the name of modernity
Inhumanistic Education System
Why have we failed to address this problem ?
Inhumanistic Education System Wrong Philosophy of Human Life No reverence for Mother Nature Blind following of Western model of development Soulless Science and Technology E f N t l Excess uses of Natural resources Damage that people inadvertently inflict on the environment Lack of understanding of Core Problems by pseudo- Lack of understanding of Core Problems by pseudo-intellectuals. Lack of responses to water crisis by the societyp y y Sleeping and Senile Society
What do you mean Sustainable Development ?y p
Sustainable development is the development thatSustainable development is the development thatmeets the need of the people without jeopardisingthe ability of future generation to meet their ownneeds.
SustainabilitySustainability requires that human activity only uses nature's resources at a rate at which they can be replenishedcan be replenished naturally.
Accelerated development Slow but sustainable development

Origin of water(Ancient western views)
Cause of ground water: Sea water is driven into rocks by Cause of ground water: Sea water is driven into rocks by wind. (Thales 624-546 BC )
Water of seas rivers springs etc come from a large Water of seas, rivers, springs etc. come from a large underground reservoir and go back to the same. (Plato 427-347 BC)
Water of springs etc. is derived from the underground water through system of openings. (Aristotle 384-322 BC).
f ll b h f d d d Rainfall cannot be the source of springs and underground water, because it penetrates only a few feet into the earth. (Annacus Sencca 6BC-65 AD)

today.
Water bodies : Talabs (ponds), kunds (wells), and baories (stepwells), etc .
All the talabs have a natural catchment. The kunds and baories are located below the talabs, so that even the seepage from the latter is not lost.

Grand Anikut : Kallanai

( f ) h h5.4 m (18 ft.) high, across the main stream of the Kaveri.
This Grand Anicut (Kallanai), built by the Chola King Karikala around the first century AD, is one of the oldest water diversion or water regulator structures in the world, which is still in use.
Introduction to Grand Anicut
The peculiar slope of 1:2000 ~ facilitates long channels to be created without silting, irrigating the THANJAVUR DELTA
R. Kollidam
R .Cauvery Grand Anicut
Grand anicut was built at just downstream of the confluence of river Kollidam and Cauvery.
This oddly shaped Grand Anicut was designed to increase the sediment transport to the distributary unlike modern dam.
The area irrigated by the ancient irrigation network is about 69,000 acres (28,000 ha). By the early 20th century, the

69,000 acres (28,000 ha). By the early 20th century, the irrigated area had been increased to about one million acres.
The Grand Anicut was renovated in 1838 and this measure immediately proved to be a great success. Later Cotton [1874: 23-26] id thi t ib t26] paid this tribute:
... it was from them (the native Indians) we learnt how to secure a foundation in loose sand of unmeasured depth. In fact, what we learnt from them made the difference between financial success and failure, for the Madras river irrigations executed by our engineers have been from g y gthe first the greatest financial successes of any engineering works in the world, solely because we learnt from them ... With this lesson about foundations, we built bridges, weirs, aqueducts , and every kind offoundations, we built bridges, weirs, aqueducts , and every kind of hydraulic work ... we are thus deeply indebted to the native engineers.
The ancient Indian engineers have created irrigation system with innumerable small reservoirs with networkssystem with innumerable small reservoirs with networks of irrigation channels.

Bamboo Drip Irrigation in Meghalaya
Used by tribal farmers of Khasi and Jaintia hills
Bamboos divert water from perennial springs on hilltops to the lower reaches by gravity
18-20 litres of water entering the gbamboo pipe system per minute gets transported over several hundred meters and finally gets reduced to 20-meters and finally gets reduced to 2080 drops per minute at the site of the plant.

Inundation channel Bengal Flood Plains
According to Sir William Willcocks, a British irrigation expert;
Floodwater enters the fields through the inundation canals The waters brings in rich silt and fish The fish fed on mosquito larva and helped check malaria in this region.It was prevalent just before 300 years back and got destroyed during British Rule.
Lessons from ancient Wisdom ? Solve the water problem in integrated manner. Adopt proper life style respecting Mother Nature. Adopt proper life style respecting Mother Nature. The meaning of sustainability in modern times should be re-evaluated in light of ancient public works and management practices. Technological developments based on sound engineering principles integrated with local culture and traditionalprinciples integrated with local culture and traditional knowledge system that can have extended useful lives. Active participation of community in solving water problems.p p y g pIn water-stress areas, development of an effective water resources management program is essential.
