Dubai: The Middle East is confronting an intensifying water crisis, with rising temperatures, frequent droughts, and population growth compounding long-standing scarcity. Governments across the region are turning to desalination and water innovation to secure their future, positioning the Middle East as a global leader in water technology.
According to Anadolu Agency, the region holds only 2% of the world's renewable freshwater, and 83% of the territory faces severe water scarcity, with projections from the World Resources Institute estimating that 100% of the population will face acute scarcity by 2050.
A study published in the Nature journal in January noted that the MENA region accounts for 41.8% of global operational desalination capacity, with approximately 5,000 plants producing 28.96 million cubic meters of water per day. Governments are planning to nearly double this capacity between 2024 and 2028, having already contracted an additional 20.9 million cubic meters per day of new output, according to the National.
Investment in desalination infrastructure has seen a massive surge. Between 2006 and 2024, the region invested $53.4 billion in capital expenditure, representing 47.5% of total global spending during that period. Total investment is now projected to rise to $100 billion by 2030, reflecting both regional demand and the global imperative for freshwater resources, which is expected to rise by up to 25% by 2050.
Desalination has become critical for domestic water supply across the Gulf states, which rank among the five most water-stressed countries globally, according to the World Resources Institute's Aqueduct Water Risk Atlas. Kuwait, for instance, sources 90% of its drinking water from desalination, supported by major plants providing a cumulative capacity of over 2.2 million cubic meters per day. Oman relies on desalination for 86% of its water needs, supported by solar-powered plants such as the Musandam facility. In Saudi Arabia, 70% of water needs are met through desalination, with plans to significantly increase output by 2030.
The UAE, Qatar, and Bahrain are also heavily invested in desalination technologies, with the UAE operating approximately 70 major plants. Meanwhile, Israel has emerged as a global pioneer in water reuse and desalination, with significant capacity to meet urban demand.
The region is witnessing a technological shift from older thermal methods to Sea Water Reverse Osmosis (SWRO), which is less energy-intensive. Saudi Arabia has been a focal point for water innovation, with investments in facilities like the Toray Membrane Middle East Factory in Dammam. The region is also exploring sustainable desalination solutions, such as Oman's solar-powered Musandam plant and Saudi Arabia's collaboration with Ebb Carbon to decarbonize desalination at scale.
Despite these advancements, the region faces challenges in cost and energy demands. Desalinated water in Saudi Arabia and the UAE costs around $1.50 per cubic meter. Experts warn that balancing technological growth with sustainable resource management will be key to addressing the crisis.
Strategically, the reliance on a few dozen 'Mega-Plants' has heightened security stakes. These facilities are viewed as 'critical infrastructure' at extreme risk during regional conflicts. Recent conflicts have already seen direct hits on water infrastructure, raising concerns over the vulnerability of such critical facilities. Geopolitical analysts warn that strikes on water infrastructure are designed to pressure governments, although this restraint has limits.
The current situation highlights the urgent need for the Middle East to balance expanding desalination capacity with responsible management of environmental and economic resources to address the intensifying water crisis effectively.
