The government is moving away from traditional and expensive rock revetments to combat coastal erosion, instead championing innovative, nature-based solutions and the use of construction waste, the Minister of Climate Change, Environment and Energy, Ali Shareef has revealed.
Speaking during a press conference held at the President’s Office, Minister Ali Shareef highlighted that while laying large boulders has been the long-standing method to tackle erosion, it is an exceptionally costly endeavour.
He revealed that just seven years ago, the installation cost for a single linear metre of rock protection could reach between USD 6,000 to USD 7,000, including project mobilisation fees. Faced with these exorbitant expenses, the Ministry is actively seeking more sustainable and economically viable alternatives.
"We are looking at finding a solution for coastal protection using nature-based solutions as well as construction waste. There are some projects in the ministry targeting nature-based solutions; I think some projects are already underway. Some designs have nature-based solutions in them,” he explained.
This new approach involves rigorous research to ensure that materials and methods successful in other nations are suitable for the unique environmental conditions of the Maldives.
In consultation with the Cabinet, President Dr Mohamed Muizzu recently directed the Ministry of Finance and Public Enterprises to arrange financial assistance, such as a research grant, to conduct a formal study into finding a cost-effective, resilient, and environmentally friendly solution.
This study will specifically explore using construction and demolition waste or other materials to replace the boulders primarily required for shore protection and harbour construction. Additionally, the Ministry plans to consult with international companies that specialise in modern, technologically advanced equipment for coastal protection, signaling a comprehensive move towards a more sustainable future for the nation's vulnerable shores.
