| Summary: | The Working Group on the Effects of Extraction of Marine Sediments on the Marine Ecosystem (WGEXT) develops the understanding to ensure that marine sand and gravel extraction is sustainably managed and in order to adopt mitigative measures.WGEXT has been monitoring the rate of marine sediment extraction in the North Atlantic, including the Baltic and North Sea for almost 40 years. The group is developing a database and associated ‘WGEXT Dredging Dashboard’ to document current extractions by end use, leased areas and, where possible, the footprint of dredged areas, all in the perspective of the long-term trends since 1993. The Dashboard can be found at https://rconnect.cefas.co.uk/content/26. Although not all member countries provide annual data, the WGEXT inventories are representative of activity in the ICES region. Volumes extracted have shown a spectacular increase from a few hundred thousand m³ per year in the early 1970s to millions m³ in the 1990s and tens of millions m³ in recent years. Over the last ... |
