Water scarcity in the Middle East and North Africa (MENA) region has moved from a long-standing structural challenge to an urgent existential concern. Rising temperatures, prolonged droughts, erratic rainfall, and rapid population growth are colliding in one of the world’s most water-stressed regions. Climate change has intensified these pressures, pushing governments to rethink how water is produced, managed, and sustained. Against this backdrop, MENA has emerged not merely as a victim of scarcity, but as a global laboratory for water innovation-particularly in desalination and related technologies.

This shift was prominently showcased at the Innovation-Driven Water Sustainability Conference held recently in Jeddah. The event underscored Saudi Arabia’s growing leadership in water innovation and its broader ambition to position the region as a global hub for water security solutions. With freshwater resources dwindling across the Arab world, governments are no longer experimenting at the margins. They are committing to bold investments, large-scale partnerships, and long-term strategies that seek to transform scarcity into resilience.

Water scarcity has always shaped political, economic, and social realities in MENA, but the scale of today’s challenge is unprecedented. Unpredictable weather patterns have disrupted traditional water cycles, while urbanization and industrial growth have driven demand sharply upward. In response, MENA governments are planning to nearly double their desalination capacity by 2030. Already, the region accounts for around 60 percent of global desalination capacity-a staggering figure that highlights both its dependence on the technology and its dominance in the sector.

Investment trends reflect the urgency of the moment. Regional spending on desalination and water infrastructure is expected to rise from approximately $39.3 billion in 2022 to nearly $100 billion by 2030. This expansion is not happening in isolation. Globally, freshwater demand is projected to increase by up to 25 percent by 2050, while the MENA population alone is expected to grow by roughly 30 percent between 2020 and 2050. These demographic and environmental realities are placing immense strain on already-limited natural water resources, making desalination not just an option, but a necessity.

Saudi Arabia stands at the center of this transformation. The Kingdom has announced plans to increase its desalination capacity by 10 percent, reaching 17.8 million cubic meters per day by 2030. Desalination is already a cornerstone of water supply across the Gulf. In Kuwait, nearly 90 percent of drinking water comes from desalination. Saudi Arabia relies on it for around 70 percent of its potable water, while Oman and the UAE depend on it for approximately 86 percent and 42 percent, respectively. These figures illustrate how deeply embedded desalination has become in everyday life, governance, and economic planning.

Beyond expanding capacity, Saudi Arabia is also focused on localizing technology and strengthening industrial self-sufficiency. A significant milestone came with the inauguration of the Toray Membrane Middle East Factory in Dammam by Eastern Province Governor Prince Saud bin Naif. The facility, the largest of its kind in the region, represents a joint venture between Saudi Arabia’s Abunayyan Holding and Japan’s Toray Industries. With an investment exceeding $267 million, the factory is expected to produce around 300,000 membranes annually. More than a manufacturing site, it symbolizes a strategic effort to localize critical components of the desalination supply chain and reduce dependence on imports.

Yet Saudi Arabia’s ambitions extend beyond conventional desalination. Recognizing the environmental costs of energy-intensive water production, the Kingdom has begun exploring ways to decarbonize the process. A pioneering partnership between the Saudi Water Authority and US-based Ebb Carbon aims to reduce carbon emissions associated with desalination operations. This initiative marks the world’s first large-scale effort to address desalination’s carbon footprint directly, aligning water security goals with broader climate commitments. As energy use becomes an increasingly sensitive issue, such innovations may determine whether desalination can remain viable in the long term.

Other MENA countries are also pushing the boundaries of sustainable water solutions. Oman, for example, inaugurated its first solar-powered desalination plant in Musandam in mid-2025. Powered entirely by renewable energy and using reverse osmosis technology, the facility converts seawater into potable water while significantly reducing carbon emissions. This project represents a critical step away from fossil fuel dependence and demonstrates how renewable energy can be integrated into water infrastructure without sacrificing reliability.

Technology lies at the heart of MENA’s water evolution. The region is not only leading in desalination capacity but also investing heavily in advanced processes such as reverse osmosis and multistage flash distillation. Saudi Arabia and the UAE host some of the largest desalination plants in the world. The Kingdom’s Riyadh Desalination Plant alone produces over one million cubic meters of water per day, while Qatar’s Ras Abu Fontas A plant generates more than 400,000 cubic meters daily using advanced reverse osmosis systems. These facilities are engineering marvels, reflecting decades of accumulated expertise and continuous innovation.

As desalination capacity expands, MENA’s influence in the global water market is growing. Countries across the region are increasingly sharing expertise, technology, and operational models with other water-stressed nations. In this sense, MENA is evolving from a regional consumer of water solutions into a global exporter of knowledge and innovation. For countries in Africa, South Asia, and parts of Latin America facing similar challenges, the MENA experience offers both inspiration and caution.

Despite these achievements, desalination is not without serious challenges. One of the most pressing is the cyclical relationship between water production and energy consumption. Desalination plants require vast amounts of energy, not only to process seawater but also to cool facilities and associated power infrastructure. As water demand rises, energy demand increases in parallel, which in turn drives higher water usage for cooling. This feedback loop places mounting pressure on both water and energy systems, raising questions about long-term sustainability-especially in a warming climate.

Cost remains another major obstacle. According to World Bank estimates, desalinated water in Saudi Arabia and the UAE costs roughly $1.50 per cubic meter. While governments often subsidize these costs, the financial burden ultimately filters down to consumers. In lower-income areas, high water prices can exacerbate inequality and strain household budgets. For governments seeking to balance economic growth, social stability, and environmental responsibility, managing the cost of desalination is an increasingly delicate task.

The future of water sustainability in MENA, therefore, cannot rely on capacity expansion alone. The region now faces a more complex challenge: how to integrate technological ambition with environmental stewardship and economic inclusivity. Desalination will remain indispensable, but it must be complemented by water conservation, demand management, wastewater recycling, and greater efficiency in agriculture and industry.

A truly sustainable water future for MENA will require holistic strategies that recognize the interdependence of water, energy, climate, and society. Innovation must go hand in hand with responsible governance, regional cooperation, and long-term planning. Only by balancing progress with prudence can the region transform its battle against water scarcity into a durable model of resilience-one capable of sustaining both people and ecosystems in an increasingly uncertain world.
