By the summer of 2001, most of Iranhad been suffering a three-year drought, theworst in recent history. Water rationing was inplace in Tehran and other cities, and largeproportions of the country's crops andlivestock were perishing. Yet many academicsand other experts in Iran insist that the watercrisis is only partly drought-related, andclaim that mismanagement of water resources isthe more significant cause. Underlying thisdiscussion is a complex of overlapping yetoften conflicting ethical systems – Iranian,Islamic, and modernist/industrialist – whichare available to inform water policy in Iran. Areview of the various arguments about thenature of the crisis and the range of solutionsthat have been proposed, including precedentsfrom traditional Iranian water management andthe ethics of water use in Islamic law,suggests that Iran's own cultural heritageprovides alternatives to wholesale adoption ofWestern models.
