Rewriting Water Management in Iran

Efficient management of demand and developing effective resource management techniques (compared to water transfer projects) would be more practical in addressing water crisis, but in practice have been largely neglected in Iran.
The experience in other countries like China shows that water diversion schemes normally impose prohibitive costs and their (ecological and social) harm far outweigh the anticipated help. So these are not necessarily optimal solutions to fight water paucity, in particular in the long term
For example, work on China’s South-North water transfer project (the biggest inter-basin transfer scheme in the world), started in 2002 and ended after 12 years.
