    General Descriptioneffect/impact onCase Studies Where This Pressure Is PresentPossible Restoration, Rehabilitation and Mitigation MeasuresSand and gravel are crucial resources for economic development activities, such as road building and concrete production. As a result, sand and gravel mining is a major economic activity that is often carried out within river channels and floodplains. Because annual extraction rates often greatly exceed fluvial transport, these activities lead to river bed incision, disconnection of the river from its floodplain, depression of water table levels in the alluvial aquifer, and sometimes a comple...

In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world’s use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone. This production represents enough concrete to build a wall 27 metres high by 27 metres wide around the equator. Aggregates also contribute to 90% of asphalt p...
