Water supply will see a 40% increase in demand in the coming decade and the topic of increasing the supply is at the heart of the issue. Agriculture uses 70% of the world's water and the water problem can be solved by disciplined agricultural techniques such as reduction of over irrigation, use of drip irrigation, sprinklers, fertilizers, Genetically Modified crops. Usage of better irrigation techniques will also boost the underground water levels. Along with these proper cold storage and transportation of agricultural produce is important as their loss should be seen as use of more water or more drop per crop. Other methods such as river linking, creating huge dams for water storage, treating sea water, bore wells are expensive and take a long time to implement.
