Sand mining is conducted mainly at open pits, beaches, inland dunes or from the dredging of ocean and river beds.
Sand is mined primarily to produce concrete for use in construction but this little-noticed and largely unregulated activity has serious costs because it damages rivers and wreaks havoc on coastal ecosystems and has even wiped away entire islands.
The growing demand for sand is driven by rapid urbanisation, including the ongoing building boom in Cambodia. and global population growth.
