Description

Sand and gravel are used for coastal protection and construction. Sand and gravel extraction can occur inland but is more common at sea. Generally, sand extraction is more common than gravel extraction.

MSP Challenge

Sand & Gravel Extraction contribute to the following pressures on the ecosystem:

Return to shipping.

According to the "Noordzeeloket", organisations with a permit can extract sand and gravel seawards from -20m depth isoline. About 12 million m3 sand per year is used to maintain the coast and 13 million m3 per year as filling material onshore (Noordzeeloket, accessed on 2022/04/25).

Data Source

HELCOM HOLAS II Dataset: Extraction of sand and gravel (2017)

Original Title

Extraction of sand and gravel

Description

"The dataset contains sand and gravel extraction activity during 2011–2015. The dataset is based on data submission by HELCOM Contacting Parties in response to data request. The dataset is quality assured and contains data from all the Baltic Sea countries. Common extraction sites with information on volume of extraction was included in the dataset. The other extraction sites (building sites, exclusive sites) had only summed data for all the sites, as volumes of extraction in specific sites was classified as confidential information. For these sites the volumes was calculated from reported sum of "other extraction areas". The amount was equally divided between corresponding extraction areas. For some common extraction sites a shared amount was reported."
