Bahrain recently reported that an Iranian drone struck a water desalination plant, marking a significant escalation in the ongoing tensions between Iran and a coalition that includes the U.S. and Israel. This unique attack highlights the vulnerability of Gulf nations, which depend heavily on such facilities for their water supply.
Desalination plants convert seawater into potable water, essential for drinking, agriculture, and industry. This process can be done through thermal methods or membrane technologies, with reverse osmosis being the most popular method in the Gulf region. The U.S. Department of Energy explains that desalination involves heating water to create steam, which leaves impurities behind, or using semi-permeable membranes that allow water to pass through but block salts and other contaminants.
In the Gulf, where natural freshwater is limited due to dry climates, desalination plays a crucial role. A 2020 report from the Gulf Research Center stated that groundwater and desalinated water account for about 90% of the area’s water resources. More than 400 desalination plants dot the Arabian Gulf coast, providing the majority of the water supply.
As of 2023, Gulf Cooperation Council (GCC) countries contribute to around 60% of global desalination capacity, producing nearly 40% of the world’s desalinated water. For example, in Kuwait, 90% of drinking water comes from desalination, while Saudi Arabia leads globally in desalinated output.
The historical context is alarming. During the Gulf War, Iraq targeted Kuwait’s desalination capabilities, which severely affected Kuwait’s water supply. A hydrologist, Raha Hakimdavar, points out that attacking these plants can disrupt food production and create additional challenges for a region that heavily relies on food imports.
Experts like Naser Alsayed stress that any damage to desalination facilities poses risks not only to water supply but also to economic stability. In smaller GCC countries like Bahrain and Qatar, where reliance on desalination is higher, the impacts can be particularly severe.
Hakimdavar emphasizes the psychological toll of such attacks. Water is vital for life, and fears of supply disruptions can lead to panic among populations.
To enhance water security in the Gulf, Alsayed argues for better regional collaboration. The GCC has frameworks like the Unified Water Strategy 2035, but more efforts are needed to implement integrated plans. Developing shared water reserves and diversifying sources—like smaller, renewable energy-powered desalination plants—could reduce the risks associated with relying on a few large facilities.
As geopolitical tensions rise, the focus on water security must evolve. Experts agree there’s no immediate replacement for desalination in the GCC, making it crucial to strengthen and diversify water resources now and for the future.
