The Gulf region's reliance on desalination plants for potable water has long been a critical vulnerability, as highlighted by a CIA assessment from 1983. This vulnerability was thrust into the spotlight recently when Iran accused the US of attacking a desalination plant on Qeshm Island, followed by Bahrain's announcement of a similar attack on its own plant, allegedly by Iran. The potential for a devastating chain reaction of attacks on these crucial water sources was averted, but why?
The Water Crisis in the Gulf
The Gulf's water scarcity is a result of low and unpredictable rainfall, coupled with a lack of large, permanent rivers. Historically, the region managed with limited groundwater, but the growth of the oil industry post-1950s led to a surge in demand, depleting aquifers and forcing countries to turn to desalination. Today, countries like Saudi Arabia, Oman, the UAE, and Kuwait heavily rely on desalination, with Saudi Arabia sourcing 70% of its drinking water this way. Even Israel, with access to the Jordan River, relies on coastal desalination plants for half its potable water supply.
A Strategic Weakness
The region's dependence on a few large coastal desalination plants makes them vulnerable to attacks. As Nima Shokri, director of the Institute of Geo-Hydroinformatics, points out, "Many cities depend on a small number of large coastal plants, meaning a successful strike could disrupt drinking water supplies within days." This vulnerability is not lost on observers, who note that targeting these plants could quickly create water shortages and potentially lead to civil unrest.
Environmental and Humanitarian Concerns
Attacks on desalination plants not only disrupt water supplies but also have environmental repercussions. The release of chemicals like sodium hypochlorite, ferric chloride, and sulfuric acid could have severe ecological impacts. Additionally, the potential for humanitarian crises is high, as these plants are critical civilian infrastructure. Escalating attacks on water systems could invite international condemnation and widen the conflict.
Iran's Water Woes
While Iran is less reliant on desalination, it faces its own water challenges, including a severe drought exacerbated by climate breakdown and over-extraction of groundwater. Retaliatory attacks on Iran's water infrastructure could further compound these issues, damaging reservoirs, pumping stations, or treatment plants and worsening existing water shortages.
A Promise Uncertain
In 1983, Tehran promised its Arab neighbors it would not attack their desalination plants. However, with the recent threats of "eye for an eye" warfare from Iran's parliament speaker, the future of this promise is uncertain. The potential for a devastating cycle of attacks on critical water infrastructure remains a very real concern.
What makes this situation particularly fascinating is the delicate balance between strategic vulnerabilities and the potential for widespread humanitarian crises. From my perspective, it's a stark reminder of the interconnectedness of infrastructure, the environment, and human well-being, especially in regions facing water scarcity.
