Iran’s climate varies from arid to semiarid, but the country’s use of groundwater is three times higher than the global average (1). In the past few decades, groundwater extraction through pumping has caused irreparable damage to Iran’s plains (2). The groundwater supply, which is decreasing by 6 billion cubic meters annually, is the source of about 55% of Iran’s water consumption (3). Iran must take steps to protect the quality and quantity of its groundwater.
