HOW ANCIENT INDIA COPED WITH WATER ISSUES
Is it not ironic that with an
estimated 400 million hectare meters (MHM) of rain, India’s annual
requirement at the turn of the century was a quarter of that at 100 MHM?
With a billion plus to cater for
today, corresponding demands for agriculture etc. may have gone up, but still nowhere
near what is available and allowed to flow off for want of conservation.
The saddest part:
This is a monsoon dependent country
with a Hoary Experience in saving up to 66% of precipitation, on an “as is
where is” basis; the antithesis of the 20 odd % in magnificently humongous dams
inherited from an Occidental culture, showing off its power over Nature.
That famed 66% happened in
pre-British India, testified by Major R H Sankey in 1866 when taking charge in
Mysore (remember the administration of
Tipu Sultan?). He wrote:
“…… to such an extent has the
principle of storage been followed that it would now require some ingenuity to
discover a site …suitable for a new tank….”.
That then was the dictum of ancient
India water conservation:
Store water where it rained.
Since Time Immemorial, hundreds of
thousands of reservoirs known by different names testifying their universality,
dotted the countryside, from the hilltop sources down to the sea, overflow of
one flowing down to the next, in natural catchment areas.
The water bodies allowed percolation,
supplemented soil moisture,
reduced soil / land erosion and maintained
atmospheric humidity. No long canals to make for seepage,
siltation, salinity and evaporation that plague our modern dam canals.
Anyone or everyone could sponsor a
tank: king, commoner, even the philanthropic village prostitute. The Arthashastra is still a mine of information. Water
bodies varied in size and depth to irrigate command areas, from ten lowly acres
to tens of thousands.
The creation of such massive numbers
of water conservation bodies threw up an amazing range of specialized Castes,
each expert in different aspects, from stone and earthworks, to reservoir and
well construction, weirs, canals and channels, even distribution --- usually
entrusted to traditionally landless Nirkuttis who had no stake in the
water. To this day, descendants of those
castes remain the backbone of irrigation and R&B labor gangs.
Maintenance was communal before the monsoon
onset. Tanks were drained and cleared; silt removed, distributed as fertilizer
within the community. Every household
participated, personally or nominees … more like a village mela with all those
accouterments too.
Today surveys bemoan the poor
penetration of piped water in Kerala – totally overlooking their rich heritage
of wells for drinking and irrigation purposes;
Bengal’s legendary prosperity was drowned
in malaria and poverty, after the destruction of the 2000+ year old overflow
irrigation canals (similar to those of the Nile, no one knows who learnt from
whom.) Those broad shallow canals
irrigated and fertilized the soil and bred millions of fish feeding off
mosquitoes’ larvae: a unique combo of health and plentitude that bred
generations of Bengali artists and scientists.
It was these developments from all
over the country that powered
The India Fable.
Desi Jugaad, (Innovation) anyone?
