Dubai has unveiled a plan to shield its iconic coastline from the effects of climate change, earmarking $96.7 million and a timeframe of 1.5 years to implement the project. The strategy entails utilizing over half a million cubic meters of sand to bolster the natural protective barriers of the shoreline. Experts believe this will help safeguard against rising sea levels, an issue that is bound to impact coastal cities worldwide.
According to Professor Gerd Masselink, a coastal geomorphologist from the University of Plymouth in the UK, there are two primary approaches to addressing shoreline problems caused by shifting weather patterns. One method involves employing "hard engineering" structures such as seawalls and groynes, which are rock barriers that prevent the movement of sand, rocks, and other components of the shoreline.
The alternative approach, which the Dubai government has opted for, falls under the umbrella of "soft engineering." A leading technique within this category is beach nourishment, or in this case, sand replenishment. "This is becoming increasingly popular because it's at the forefront of soft engineering and nature-based solutions," he explained. "You're trying to mimic nature by replenishing the sandy beach rather than pouring concrete on it."
In the Netherlands, this approach has proven particularly successful, with sand being dredged from the North Sea and added to the shoreline. The Maldives is another part of the world where this is practiced, with islands being raised for increased resilience. "This is widely used to combat coastal erosion, especially in the face of climate change and rising sea levels," he added. Masselink believes this method offers a long-term solution, spanning the next 50 years.
Beyond its environmental focus, the project also aims to enhance tourism offerings. Deira will be home to Dubai's first 300-meter beach dedicated to around-the-clock nighttime swimming. Additional features include a 5-kilometer pedestrian walkway connecting 11 kilometers of cycling and running paths lined with trees, and a 200-meter floating bridge linking both sides of Al Mamzar Beach.
A total of 1,400 parking spaces for cars and buses will be provided, including charging stations for eco-friendly vehicles,as well as integrated networks of potable water stations, irrigation systems, and sewage drains spanning 5 km. Beach lifeguards will be equipped with the latest AI-powered technology, while enhanced surveillance will be implemented through over 100 advanced cameras linked to the Dubai Municipality and Police central control rooms.
