By many a projections, it is described that 'Water is going to be the Oil of 21st century.'
But what makes the situation more grim is that there can be an alternative for oil, but not for water.
Water wars are already not unimaginable. We have had states fighting for Water from inter-state rivers. It is only a matter of time that this goes international. Water and food-scarcity are far more urgent issues than the importance they are given.
Environmental refugees due to the lack of availability of natural resources are going to be huge challenge for policy-makers the world over in the not-so-distant future. For a billion plus population like India Roti, Kapda, Makaan, mobile can take a back-seat.
Potable water will be an alarming issue. No amount of distillation processes of sea-water will be able to replace fresh water resources.
To start with, rain-water harvesting facilities could be made a compulsion for new constructions along with earthquake resistant designs. In a country with a large experience of earthquakes and water scarcity, these things do not need Einsteins to give a thought. Ah! I wish the people who heed only to 'phoren babas' information get such a solution from them, our netadom & babudom will then grab it with both hands.
