Nature-based Solutions

Nature-based Solutions combining hard engineering with ecosystem creation, from beach nourishment to reef, wetland, mangrove, seagrass and coral restoration.

Description

DEME’s Nature-based Solutions (NbS) strategy builds ecological principles into engineering, balancing grey (hard) structures with green solutions.

Key features

  • Sandy solutions such as beach nourishment and dunes
  • Seabed landscaping at borrow pits
  • Beneficial use of soft sediments
  • Ecologically enhanced hard engineering
  • Biogenic or artificial reefs
  • Wetland, mangrove, seagrass and coral restoration
  • Habitat creation inside offshore wind lease areas
