In 2019, the UNEP noted existing solutions that could be implemented to reduce damage to ecosystems, as well as risks to communities and workers around sand extraction sites. The report called for an overhaul of how we design and construct buildings and infrastructure to reduce sand and gravel demand to responsible levels.
13.6.3.3.3. Sand and gravel-mining landscapes: Rivers and floodplains Because it is needed for so many construction purposes in such large volumes, sand and gravel extraction is a widespread activity along river channels throughout the world, especially close to growing urban areas.
11/95 Sand And Gravel Processing 11.19.1-1 11.19.1 Sand And Gravel Processing 11.19.1.1 Process Description1-6 Deposits of sand and gravel, the unconsolidated granular materials resulting from the natural disintegration of rock or stone, are generally found in near-surface alluvial deposits and in subterranean and subaqueous beds.
Since both contain sand and gravel, it is assumed that the material is consistent between the two pits. Two other test pits, C and D, are dug. The new pits are 300 feet apart. If all the test pits show sand and gravel, it is assumed that the entire area, 300 feet by 300 feet contains sand and gravel.

"If extraction is below the riverbed level, groundwater recharge from rivers to floodplain aquifers may be severely reduced. This will impact adversely on bores and wells in the area." (Sec. 6.1.6. Page 20.) "Extraction of river sand and gravel often involves direct clearing of vegetation (that stabilizes soil). … Construction of access ...
States remained a net exporter of industrial sand and gravel, although U.S. exports of industrial sand and gravel decreased by 34% in 2020 compared with those of 2019, also a result of the global pandemic. The United States was the world's leading producer and consumer of industrial sand and gravel based on estimated world production figures.

6 SAND AND GRAVEL EXTRACTION 6.1 DESCRIPTION Today there is a growing demand for sand and gravel. Aggregate extraction of sand from the seabed provides an alternative source to existing sand quarries on land. While permits have been issued for sand extraction to date no permits have been issued for gravel extraction.

A Mining Plan describes how the gravel pit will affect the area and must include the detailed information listed in Rule 6.3.3. Prepare a Reclamation Plan to describe the timing, procedure, and criteria and materials that will be used to reclaim the affected land to the proposed future land use in accordance with Rules 6.3.4(1) and 3.1.
A Sand and Gravel Extraction Policy for Non Tidal Rivers in NSW Executive Summary . Evidence of environmental problems associated with river sand and gravel extraction is increasing. So also is the community's expectation of river systems. Future management decisions must be based on the principle of sustainable development
Qatar imports over $6 billion worth of sand annually. The immense growth of human infrastructure — booming cities, roads, concrete, glass, electronics, and shale gas fracking — now requires such a massive extraction of sand and gravel, that we are now destroying rivers, lakes and ocean ecosystems just to dredge up billions of tonnes annually.

Advanced economies use a lot of aggregate, about 6 to 12 tonnes per person per year.. Most aggregate comes from hard rock quarries but some is sourced from river gravels. It is well know that mining gravel from rivers can cause a lot of problems.. Moving gravel miners out of the river and onto the floodplain is often seen as a safer option but there are substantial risks.

Sand mining concessions in national parks and internationally recognized wetlands were killing mangroves and sea grasses that were home to Irrawaddy dolphins, green turtles, and hairy-nosed otters, one of the world's rarest mammals. Sand and gravel are mined on a huge scale around the world. But few global data are collected on this activity.
