The United Arab Emirates (UAE), famous for its skyscrapers and luxury, faces a big problem: water scarcity. The desert country has no permanent rivers or lakes and very little rainfall. It depends mainly on desalination to get fresh water. Around 42% of UAE's water comes from almost 70 desalination plants, which produce 14% of the world's desalinated water. These plants use techniques like Reverse Osmosis and Multiple-Effect Distillation. Groundwater from ancient aquifers is also used, but it is running out fast due to overuse. The UAE is also recycling wastewater for irrigation and industries, aiming to reuse 95% of treated water. It has built large reservoirs and emergency tanks, and is even exploring importing water from neighbors. Besides these, the UAE benefits from wadis—seasonal valleys that fill with water after rain, especially in the Hajar Mountains. These wadis form temporary pools and help refill underground aquifers, supporting agriculture and nature. To secure water for the future, the UAE launched the Water Security Strategy 2036. This plan targets a 21% cut in water demand, raising water productivity, reducing scarcity, and ensuring affordable safe drinking water for all. The national program also works to improve water use efficiency by 40% in key sectors like transport and industry. The UAE shows how a dry nation can lead the way in water management. Through smart planning, new technology, and strong policies, it turns water scarcity into a story of innovation and resilience.
