I felt that something is not correct in this debate then i understood the options provided are not directly linked to the question asked.
Well we can meet the land and water needs in the future,its is possible,and will be done in time.We guys think that our brilliant,intellectual fellowmen are not working on this?Yes some strong regulations will be brought ahead to serve the sole purpose of making survival possible for our future generation.Five year plans,and government policies....we were,we are and (i dont hope) we will be dependent on the civic bodies....We take government for granted....we think provision of basic necessities by government bodies is our birth right....we are wrong.
There are so many water resources privately held...wells ,tube wells...make them semi private.
Promote joint family culture this will save unwanted use of land...only one residence per family should be mandatory...no one should be allowed to purchase more than one.this sounds rude.....but is a necessity.
make rain water harvesting mandatory,and when practised shud be given some relaxation in water tax.
Club water and electricity bills together,and all taxes including water electricity in one paper.This will avoid non-payment of water n electricity bills,especially in rural areas and that too the sahukars...the rich farmers,politicians they are the culprits.
Save water and land now and u will have it for future.
