Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have ...
Sand mining risks and associated impacts. Most sand mining impacts are associated with the removal of substratum material, alteration of the bottom topography, sediment composition, changes in depth and current strength, and the modification of hydrologic conditions (Allsopp et al. 2013; Uscinowicz et al. 2014).Rapid removal of sand reduces groundwater recharge and may result in premature ...
The most important effects of instream sand mining on aquatic habitats are bed degradation and sedimentation, which can have substantial negative effects on aquatic life. The stability of sand-bed and gravel-bed streams depends on a delicate balance between streamflow, sediment supplied from the watershed, and channel form.

Sand and gravel are mined on a huge scale around the world. But few global data are collected on this activity.
suspended sediments from sand mining sites, but the long term, indirect and cumulative effects of mining upon the food chain are harder to study, and have not really been tackled. To study site-specific effects of instream mining would require careful measurement of mining-induced changes to baseline conditions (Kondolf et al., 2002).
Sand mining has led to deepening and widening of the Lake Poyang channel, the largest freshwater lake in China and a biodiversity reserve of exceptional importance, and to an increase in water discharge into the Yangtze River.
