Over the past decades, there has been a growing interest in exploring innovative ways to minimise the environmental footprint of coastal developments and in nature-based approaches for shoreline protection. At Mubarraz Island near Abu Dhabi (UAE), an international oil company beneficially reused ~12 million m³ of dredged material to protect pipelines, construct a causeway and create mangrove habitat to manage coastal erosion. This ‘Working with Nature’ approach has provided a cost-effective nature-based solution for shoreline protection, with added benefits for biodiversity conservation.
A contribution by Polite Laboyrie, President of CEDA, to the Paving the Waves 2020 conference is linked to the IADC-CEDA book Dredging for Sustainable Infrastructure. The book and also Mr Laboyrie’s presentation presents guidance to achieve dredging projects that fulﬁl their primary functional requirement, while adding value to the (natural and socio-economic) system.
Can nature-based solutions be mainstream solutions? Nature-based solutions have obvious advantages but have not been embraced at wider scale. The barriers which can hinder wide-scale application and the topic’s relevance to the dredging community are discussed.
The Bacton Sandscaping scheme is a large-scale beach nourishment designed to protect the Bacton Gas Terminal from cliff and beach erosion while also reducing flood and erosion risk to the communities of Bacton and Walcott, buying the time they need for adaptation to coastal change.
This study examines which and, if possible, how much more ecosystem services are provided by the most recent nature inspired coastal protection project Prins Hendrik Zanddijk, in comparison with a traditional concrete and asphalt construction.
