AquaForest: A nature-based solution for dredged sediments

AquaForest is a demonstration project led by Jan De Nul showcasing a green-grey approach, where dredged sediments are being reused to create 50 hectares of mangrove habitat in the Guayas Delta, Ecuador. The project aimed to advance knowledge on the conceptual design and eco-engineering approaches of mangrove habitats, while strengthening local engagement and generating diversified income opportunities for local communities. A new mangrove island was built in the end of 2024 and is currently being monitored to quantify the provision of ecosystem services over time with the aim of future upscaling of this type of nature-based solutions.

RESTORING OYSTER REEFS with nature inclusive marine infrastructure

While essential to coastal development and maritime industries, dredging and marine construction activities can unintentionally disrupt marine ecosystems. At Van Oord, we aim to deliver solutions for marine infrastructural developments that protect and enhance habitats and biodiversity. Over the past few years, we have explored how nature-inclusive designs can transform traditional marine infrastructure into ecosystem-supporting assets. The reintroduction of the European flat oyster to the North Sea is a key example.

Seminars & Courses

To optimise the chances of the successful completion of a project, contracting parties should, from the start, fully understand the requirements of a dredging project. IADC’s seminar strives to provide an understanding of the basics of dredging through lectures and workshops which are given by industry experts in a classroom setting for a hands-on experience.

IADC has over a hundred main and associated members.
