Inefficient irrigation wastes water

Description
Today, 70% more water is withdrawn for irrigation than in 1960
The amount of irrigated land has doubled
Crop yields can double
Only 45% of water is absorbed by crops via “flood and furrow” irrigation
Overirrigation leads to waterlogging, salinization, and lost farming income
Most national governments subsidize irrigation
Water mining = withdrawing water faster than it can be replenished
