Water Crisis in Gulf Countries in the Context of a Continuing Iran War

Dr. PK CHHETRI

Introduction

The Gulf region is widely recognized for its immense hydrocarbon wealth and strategic importance in global energy markets. Countries such as Saudi Arabia, the United Arab Emirates, Kuwait, Qatar, Bahrain, Iran and Oman have achieved remarkable economic development due to oil and natural gas resources. However, beneath this prosperity lies a profound environmental and strategic vulnerability: the scarcity of freshwater. The Gulf region is one of the most water-stressed areas in the world due to its arid climate, extremely low rainfall, and absence of major freshwater rivers. As a result, Gulf countries depend heavily on desalination technology to convert seawater into potable water for domestic, industrial, and agricultural use.

In a hypothetical future scenario involving an expanded war with Iran, the Gulf region could face not only military and economic disruption but also a severe water crisis. Desalination plants, energy infrastructure, and maritime routes could become strategic targets or indirect casualties of warfare. Because most Gulf countries rely on desalination for the majority of their freshwater supply, any disruption to these systems could rapidly lead to shortages affecting millions of people. The potential consequences would extend beyond humanitarian concerns to economic stability, regional security, and global energy markets.

Structural Water Scarcity in the Gulf Region

Water scarcity is a defining environmental challenge in the Gulf region. The natural geography of the Arabian Peninsula is dominated by desert landscapes, where annual rainfall is extremely limited and evaporation rates are among the highest in the world. Unlike many other regions, the Gulf States lack permanent rivers and rely primarily on groundwater reserves and desalination technologies to meet their water needs.

Historically, groundwater aquifers served as an important source of freshwater. However, decades of overexploitation have significantly depleted these reserves. In many cases, groundwater extraction exceeds natural recharge rates, leading to declining water tables and increasing salinity. Consequently, groundwater is no longer a sustainable long-term solution for meeting the water demands of rapidly growing urban populations.

To address this problem, Gulf countries have invested heavily in desalination technology. Desalination involves removing salts and minerals from seawater through processes such as thermal distillation and reverse osmosis. Today, the Gulf region hosts some of the largest desalination plants in the world. Countries like Saudi Arabia and the United Arab Emirates produce millions of cubic meters of desalinated water every day.

The reliance on desalination is extremely high. In several Gulf countries, desalinated water provides the majority of drinking water supplies. This technological dependence has allowed the region to support large urban centres, industrial development, and tourism despite severe natural water scarcity. However, it has also created a structural vulnerability: water security is closely tied to the uninterrupted operation of desalination facilities.

Strategic Importance of Desalination Infrastructure

Desalination plants are critical components of the Gulf’s water infrastructure. These facilities are typically located along coastlines to allow direct access to seawater, which is the primary input for the desalination process. The plants are connected to large distribution networks that transport freshwater to cities, industrial zones, and agricultural areas.

The importance of these plants cannot be overstated. In many Gulf cities, desalination provides nearly all of the drinking water consumed by residents. Without these facilities, urban centres would struggle to sustain their populations even for short periods.

However, desalination plants are also energy-intensive systems that rely heavily on electricity. Many of them are integrated with power generation facilities in so-called “cogeneration plants,” where electricity production and desalination occur simultaneously. This interdependence means that damage to energy infrastructure could also disrupt water production.

Another challenge is the limited storage capacity for freshwater in the Gulf region. Because desalination plants produce water continuously, most cities maintain only a few days’ worth of stored water. If desalination plants were to stop functioning, water shortages could emerge very quickly.Thus, desalination plants represent both the foundation of water security in the Gulf and one of its most critical vulnerabilities.

Geopolitical Tensions and the Risk of Conflict

The Persian Gulf has long been a region of geopolitical tension due to competing strategic interests, ideological rivalries, and the presence of major global energy resources. Iran, a major regional power, has had strained relations with several Gulf Cooperation Council (GCC) countries, particularly Saudi Arabia and the United Arab Emirates.

      In a future scenario of persistent direct military conflict in view of escalating tensions involving Iran, critical infrastructure in the Gulf could also become vulnerable to attack. Military strategies in modern warfare increasingly involve targeting economic and logistical assets rather than solely engaging in battlefield confrontations.

Energy facilities, ports, and shipping lanes would likely be primary targets as it is happening today. However, desalination plants could also become strategically significant due to their importance for civilian survival. Disrupting water supplies could exert pressure on governments and populations, potentially influencing the course of a conflict.

The Strait of Hormuz further complicates the situation. This narrow maritime passage connects the Persian Gulf with the Gulf of Oman and is one of the world’s most important shipping routes for oil and gas exports. Continuing military activity in this area could threaten both energy shipments and coastal infrastructure, including desalination plants located nearby.

Additionally, modern conflicts often involve cyber warfare. Many desalination plants operate using advanced digital control systems and automated processes. Cyberattacks targeting these systems could disrupt water production without physical destruction of the facilities.

Humanitarian Consequences of a Water Crisis

The humanitarian implications of a water crisis in the Gulf region would be severe. Large metropolitan areas such as Riyadh, Dubai, Abu Dhabi, Doha, and Kuwait City depend almost entirely on desalinated water. If desalination plants were damaged or forced to shut down, millions of residents could face water shortages within a short period.

Water is essential not only for drinking but also for sanitation, hygiene, and healthcare services. Hospitals, schools, and public institutions rely on stable water supplies to function effectively. A sudden disruption could compromise public health systems and increase the risk of disease outbreaks.

Furthermore, the Gulf region hosts a large expatriate workforce that supports various sectors of the economy. Many of these workers live in densely populated urban environments where access to clean water is critical. A prolonged water shortage could create humanitarian emergencies, particularly among vulnerable populations.Governments might attempt to implement emergency measures such as water rationing or importing bottled water. However, these solutions would be temporary and difficult to sustain for large populations.In extreme circumstances, water shortages could lead to social unrest, migration, or political instability. Citizens might lose confidence in the ability of governments to provide essential services during crises.

Economic and Global Implications

A water crisis in the Gulf region would also have far-reaching economic consequences. The Gulf economies are heavily integrated into global markets, particularly through energy exports, financial services, aviation, and tourism.Industrial sectors such as petrochemicals, manufacturing, and power generation require significant amounts of water. If desalination plants were disrupted, these industries might be forced to reduce operations or shut down temporarily.Tourism, a major economic sector in cities like Dubai and Abu Dhabi, would also suffer. Visitors are unlikely to travel to regions facing severe water shortages or infrastructure disruptions.

The global economy could also be affected. The Gulf region supplies a substantial portion of the world’s oil and liquefied natural gas. A major regional crisis affecting infrastructure could disrupt global energy markets, leading to price volatility and supply shortages.

International trade routes have been affected simultaneously continuing conflict in the Gulf disrupts maritime shipping through the Strait of Hormuz.Thus, the economic implications of a water crisis would extend far beyond the Middle East, potentially affecting global markets and geopolitical stability.

Environmental Risks

Another dimension of the crisis involves environmental risks. Desalination plants use various chemicals during the purification process, including chlorine and anti-scaling agents. If these facilities were damaged during military strikes, chemical leaks could occur, contaminating surrounding marine ecosystems.

The Persian Gulf is already environmentally fragile due to heavy industrial activity, oil extraction, and shipping traffic. Pollution resulting from damaged desalination plants could harm marine life, fisheries, and coastal ecosystems.Additionally, large-scale disruption of desalination operations could lead to increased reliance on groundwater extraction, further accelerating the depletion of already stressed aquifers.

Strategies for Mitigation and Resilience

Given the seriousness of these risks, Gulf countries must consider strategies to strengthen water security and resilience against potential disruption in water supply. One approach is diversifying water sources. Governments could invest in wastewater recycling and reuse technologies, which allow treated wastewater to be used for agriculture or industrial purposes. This would reduce pressure on desalinated water supplies.

Another strategy involves expanding water storage capacity. By constructing large underground reservoirs or storage facilities, countries could maintain emergency reserves capable of sustaining cities for longer periods during crises.Technological innovation also offers potential solutions. Smaller, decentralized desalination plants powered by renewable energy sources such as solar power could reduce dependence on large centralized facilities.

In addition, improving cyber security and physical protection of critical infrastructure is essential. Governments in future may invest more in air defence systems, surveillance technologies, and cyber security measures to protect desalination plants from attacks.

Finally, diplomatic efforts and regional cooperation are crucial. International law prohibits attacks on civilian infrastructure essential for survival, including water facilities. Diplomatic initiatives could reinforce norms protecting such infrastructure during conflicts.

Conclusion

The prospect of a water crisis in Gulf countries arising from a persistent Iran war highlights the complex relationship between environmental vulnerability and geopolitical conflict. Despite their immense wealth and technological capabilities, Gulf States remain highly dependent on desalination plants for their freshwater supply. This dependence creates a critical strategic vulnerability during times of conflict.If desalination infrastructure were disrupted due to military attacks, cyber warfare, or energy shortages, the consequences could be immediate and severe. Millions of people could face water shortages, public health crises could emerge, and economic activity could be severely disrupted. Furthermore, the global economy could experience significant repercussions due to the Gulf’s central role in energy production and international trade.

Addressing this challenge requires long-term planning and proactive strategies. Diversifying water sources, investing in infrastructure protection, expanding storage capacity, and promoting technological innovation can help reduce vulnerability. Equally important is the need for diplomatic engagement and international cooperation to prevent attacks on critical civilian infrastructure.

Ultimately, water security may become one of the most important dimensions of national security in the Gulf region. As geopolitical tensions evolve, ensuring access to safe and reliable water supplies will be essential not only for the survival of populations but also for maintaining regional stability and global economic balance.
