Description

We distinguish between “sand and gravel extraction” and “dredging” for MSP Challenge purposes. We define the first as the extraction of materials for coastal defence or construction, while dredging is defined as having the purpose of maintaining navigability.

Sedimentation may occur due to river influx and tides. Dredging sites are locations where sediment needs to be removed to enable or improve navigation. Dredging can occur periodically or sporadically.

MSP Challenge

Dredging sites can be edited and contribute to the following pressures on the ecosystem:

• Noise
• Bottom Disturbance

General Edition

Not applicable.

This layer is not available in the North Sea Edition.

Sand Extraction Edition

In the Sand Extraction Edition this layer is called 'Dredging Disposal Areas'. It is a combination on two types of disposal sites; Dump and Quay sites (stort en loswal) and dredging disposal areas (baggerstortgebied).

Dredging areas 2011-2016

Description

"Data set represents dredging activities around the Baltic Sea. The dataset contains information about the dredging activity and for some the type (capital, maintenance) and the year of activity as reported by HELCOM Contracting Parties in response to data request.

The dredging data is missing from Denmark."

Description

"The dataset on dredging in the European seas was created in 2014 by AZTI for the European Marine Observation and Data Network (EMODnet) and it is the result of the aggregation and harmonization of data provided by several sources from all across the Europe. It is available for viewing and download on EMODnet web portal (Human Activities, https://emodnet.ec.europa.eu/en/human-activities). The dataset contains points representing dredging sites in the following countries: Belgium, Bulgaria, Cyprus, Denmark, Estonia, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Latvia, Lithuania, Malta, Norway, Poland, Portugal, Spain, Sweden, The Netherlands and United Kingdom. Where available, each point has the following attributes: Id (Identifier), Position Information (e.g.: Estimated, Original, Polygon centroid of dredging area, Polygon centroid of dredging polygon), Country, Sea basin, Sea, Extraction Area, Year (when data is for a time period, the first year of the period is indicated), Permitted Amount (m3), Permitted Amount (t), Extracted Amount (m3), Extracted Amount (t), Extraction Type (e.g.: Harbour dredging, Estuary dredging, Sea lane), Purpose (e.g.: Maintenance dredging, Capital dredging, Others), End Use (e.g.: Beach nourishment, Commercialization, Confined deposit, Construction material, Embankment, Filling material, Land deposit, Reuse, Sea disposal, Wetland restoration), Material type (e.g.: silt, sand, gravel), Notes, Link to Web Sources. In the 2024 update, extraction data until 2023 has been included."
