Sand mining (extraction) is defined as the removal of primary () natural sand and sand resources (mineral sands and aggregates) from the natural environment (terrestrial, riverine, coastal, or marine) for extracting valuable minerals, metals, crushed stone, sand and gravel for subsequent processing (UNEP, 2019).
Mining of coastal sand bodies has gone on for as long as humans have lived near the shore. Initially it occurred on a bucketful scale and at a local level. Now it occurs on the scale of long lines of large dump trucks containing more than 10 cubic meters of sand each. As humans have devised more efficient ways to remove large volumes of sand ...

In recent years, large scale sand-mining, which is banned in St. Eustatius, has taken place at Zeelandia beach. Although efforts were made to block vehicle access to the beach, individuals have, through the removal of vegetation, created a path in between the sea grapes to drive onto the beach.
However, the process of sand mining has accelerated coastal environmental degradation to an alarming rate in many areas. As a result the government has been compelled to spend millions of dollars to combat sea erosion. This paper examines the causes and effects of coastal sand mining in three communities in the Ahanta West District of Ghana.

The effects of river sand mining can also be seen at the coast where the lack of sand replenishment can cause beaches and dunes to erode faster and therewith offer less protection against storm surges, tsunamis and sea level rise (Shaghude et al., 2012). 5. Effects on the biological environment
