Environmental Aspects of Dredging, Port and Waterway Construction around Coastal Plant Habitats
Communities of Practice
PIANC’s Working Group 157 presents international best management practices in its guidelines to protect coastal plant habitats like mangroves, salt marshes, seagrass beds, and macroalgal communities during dredging and construction activities. These ecosystems play a crucial role in climate change mitigation, offering coastal protection and carbon storage. The guide emphasizes environmental monitoring, adaptive management, impact assessment, and techniques for minimizing, mitigating, or compensating damage. It also highlights habitat restoration and beneficial reuse of dredged materials. Crafted by a team of global experts, the guidelines incorporate case studies and aim to facilitate responsible environmental management in coastal plant habitats near dredging and construction sites worldwide, albeit without mandatory compliance.
