This is Present ! Imagine the Future...
Water scarcity is becoming an inflammable issue day by day. If we do not act early we might make an irrecoverable damage.
Lets peak into the future to see what it holds for us...
The population of India is expected to stabilize around 1640 million by the year 2050.
In year 2001 gross per capita water availability was 1820 m3 / yr (today it has gone down further)
In year 2050 it will decline as low as 1140 m3 / yr
Total water requirement of the country for various activities around the year 2050 has been assessed to 1450 km3 / yr.
This is 3 times of present availability of ~500 BCM / yr ( 1 BCM = 1 cu kilometer) |
Viewed in the international perspective –
Country with water < 1700 m3/person/yr is tagged as water-stressed And < 1000 m3/person/yr as water scarce
India is water stressed today and is likely to be water-scarce by 2050. Already, many parts of the country are water-scarce
Water Usage
 Irrigation : 82 %
 Industrial : 12 %
 Drinking : 6 %
and today we are facing Drinking Water Shortage !
Do We Actually Face Water Scarcity?
Geographically India has been gifted in abundance by nature. Nature provides enough rainfall which is sufficient for our needs. But today, global Warming is resulting in unpredictable monsoon which causes less number of rainy days with high intensity.
The problem thus is not low rainfall but erratic rainfall.
The Root Cause
What happens to the abundant rainwater we receive each year?
As per Groundwater Survey & Development Agency (GSDA) of Maharashtra state.
55% Rainwater is wasted as run off
35% Rainwater is wasted as evaporation
and Only 10% Rainwater is harvested
(Very few are aware of the fact that water evaporates even in rainy season. It was observed that 800mm rainwater evaporated from a tank out of 807 mm rainfall during year 2009.)
This is because only 3% of the rainwater percolates in the ground naturally, rest just flows away i.e. run off. Existing Rainwater harvesting system manage to use only 10% of rainwater.
Thus the real cause of water scarcity is sheer mismanagement of valuable rainwater.
Food Crisis is directly related to water crisis. There would be a sharp decline in agricultural production, which will negate all of the previous efforts at food security. India will become a net importer of grain, which will have a huge effect on global food prices, as well as the global supply of food. A rise in food prices will aggravate poverty because people will have to spend larger portions of their income on food.
In addition to devastating the agricultural sector of India’s economy, the water crisis will have a big effect on India’s industrial sector, possibly stagnating many industries.
Solution to Water scarcity
The solution thus remains, is to capture the runoff water and saving of evaporation losses, i.e. converting this 80% non-productive water into productive water by percolating it in the ground. But Rainwater does not percolate automatically; it has to be recharged i.e. directed to ground. This is exactly what Kedia Farm Pattern - KFP does.
KFP can harvest 80% of rainwater i.e. 80% of rainwater is percolated in the ground.
Out of which 40 - 50% is stored as soil moisture compared to the usual 10% and the rest further infiltrates to increase ground water level.
If implemented on a large scale KFP can also revive drying rivers and wells and prevent drought and floods.
Due to its percolation ability and innovative technology, KFP is an outright solution to Water Crisis.
