Down to Earth - - LETTERS -

It is hard to be­lieve that with four per cent of wa­ter re­sources in the world, In­dia has be­come a wa­ter- stressed na­tion (“Wa­ter stress”, March 16- 31, 2014). The graphs and ta­bles used in the story were a sim­ple yet pow­er­ful way of show­ing the rea­sons be­hind the wa­ter cri­sis in the coun­try. Ir­ri­ga­tion and do­mes­tic pur­poses usu­ally re­quire ground­wa­ter, which, ac­cord­ing to the Plan­ning Com­mis­sion, is fast de­plet­ing. We need to look for al­ter­na­tive sources of wa­ter, such as rain­wa­ter har­vest­ing. This is an easy and ef­fec­tive way of col­lect­ing, stor­ing and us­ing rain­wa­ter for ir­ri­ga­tion. On the other hand, the lack of clean drink­ing wa­ter can be at­trib­uted to wa­ter pol­lu­tion caused by house­hold and in­dus­trial waste. The wa­ter cri­sis is real and is star­ing us in the face. The time to act is now. MUKTIPADA DAS Kolkata
