We distinguish between “sand and gravel extraction” and “[[Dredging Sites|dredging]]” for MSP Challenge purposes. We define the first as the extraction of materials for coastal protection or construction, while dredging is defined as having the purpose of maintaining navigability. | |||
Sand and gravel extraction can occur inland but is more common at sea. Generally, sand extraction is more common than gravel extraction. | |||

According to the "Noordzeeloket", organisations with a permit can extract sand and gravel seawards from -20m depth isoline. About 12 million m<sup>3</sup> sand per year is used to maintain the coast and 13 million m<sup>3</sup> per year as filling material onshore ([https://www.noordzeeloket.nl/en/functions-and-use/artikel-baseline/ Noordzeeloket], accessed on 2022/04/25). | |||

===Description=== | ===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." | |||

Italy: "The Adriatic studied sand deposits map with two layers: a)The potentially sand resources(offhore sand deposits); b) the dredged areas already expoited (offshore sand dredged). During the last decades the increasing amount of data acquired by ISMAR CNR provides unique opportunities to summarize knowledge of geology and shelf geomorphology with existing geotechnical and geophysical data that facilitate identification of sand resources. The volume of the entire potental fine sand available reservoir outcropping in the italian portion of the adriatic shelf seafloor has been extimated in ca. 270 x106 cubic metres. The amount of dredged material used costal nourishment in Adriatic since 1996 is 9.9 x106 cubic metres." | |||
