Iran Faces Severe Water Crisis: Rainfall Plummets 45% and Dam Inflows Decline by 29%

Iran is currently facing a severe water crisis exacerbated by a staggering 45% decline in rainfall since last year. This alarming situation is compounded by a 29% reduction in water inflow to dams compared to the five-year average, placing immense pressure on the nation amid ongoing economic challenges and soaring inflation.

The crisis is most acute in Tehran, where dam levels have plummeted to a mere 17% of their total capacity, as stated by Firouz Ghasemzadeh, the spokesperson for Iran’s water sector. He noted that since the start of the current water year, which began in late September/early October, cumulative rainfall has decreased by 45% compared to the same timeframe last year. Analysis of a 57-year rainfall record positions this year as the 53rd driest, indicating that only four years in the past 57 have experienced lower rainfall levels.

Currently, Iran is grappling with one of its most severe droughts in over half a century. This persistent water scarcity has led to widespread criticism of the Iranian government’s management of environmental resources.

• The volume of water flowing into Iranian dams since the beginning of the current water year until January 18th has decreased by 5% compared to the previous year and by 29% relative to the five-year average, Ghasemzadeh reported.
• Many regions across the country have been suffering from water shortages for over a decade, prompting farmers to stage protests urging for policy changes.
• Outflows from dams have also diminished by 9% compared to the five-year average since the onset of the water year.
• Current reservoir levels stand at 44% of total capacity, showing a slight increase from last year.

Ghasemzadeh expressed particular concern regarding the state of dams in various provinces, especially in Tehran. The five primary dams in the region are currently only 17% full, reflecting a 21% drop compared to the five-year average. This water shortage poses serious implications for agriculture and food prices, particularly in light of the inflation rate averaging around 40% over the last five years.

One of the most critical cases is the Zayandeh Rud dam in central Iran, which is alarmingly low at 13% capacity—a 28% decline compared to the five-year average. Significant reductions in reservoir levels and inflow are also evident in provinces such as Khorasan Razavi, Hormozgan, Zanjan, Markazi, and Golestan, highlighting the urgent necessity for effective water conservation strategies.

The water crisis in Iran is further complicated by regional political tensions. For instance, Afghanistan’s construction of the Pashdan Dam on the Harirud River has severely restricted water flow into Iran’s eastern provinces, endangering over two million residents in Razavi Khorasan Province who depend on this river for their drinking water supply.

This ongoing drought marks the fourth consecutive year of significant water scarcity, representing one of the most severe drought periods in over fifty years. The persistent crisis has intensified public criticism of the Iranian government’s environmental policies. Despite the government’s denials of any mismanagement, the governor of Tehran has recently acknowledged the country is “confronting a significant challenge in the water sector,” recognizing the diminishing rainfall and drained dam reserves.

Additionally, the United Nations Water (UN-Water) has classified Iran as experiencing “extremely high-water stress” in its latest annual world water development report. This report underlines that Iran, in conjunction with other countries in the Asia-Pacific region, is facing critical challenges related to water scarcity.

In conclusion, the combination of reduced rainfall, declining dam levels, and ongoing political tensions have created a perfect storm for Iran’s water crisis. Urgent action and comprehensive strategies are necessary to address the water shortages and ensure sustainable management of this vital resource for future generations.
