Sand Extraction: 1. Introduction GreenFacts

IntroductionWhere and How Much Sand and Gravel Are mined?What Are The Main Issues with Sand Mining?What Is The Specific Negative Impact from Marine Sand Mining?What Is The Impact on Coastal and Inland Erosion?What Is The Impact of Sand Mining on Inland Biodiversity and Rivers?Are There Economic Impacts Related to Sand Mining?What Can Be Done to Reduce The Problems?Which Regulatory Initiatives Should Be Applied to Manage The Issues?Sand and gravel are used extensively in construction. 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...
