Sand is the key raw material in concrete, asphalt and glass that built our infrastructure. It is also used for land reclamation as well as flood protection in coastal areas, part of the efforts to protect eroding coasts and address climate change impacts such as sea-level rise and increasingly severe storms.
The mining of marine sand and aggregates used for development and reclamation is also increasing and causing significant impacts to seabed flora and fauna. Millions of tonnes of sand has to be mined and rocks quarried to create new land. Dredging and extraction of aggregates from the benthic (sea bottom) zone destroys organisms,
This article attempts to interpret the role of sand in reclamation projects starting from below by monitoring the transformations of places and people from the …
While deep-sea mining remains a prospect for an uncertain future, many countries have been extracting sand and gravel from the sea for decades. These two loose aggregates are now among the most sought-after raw materials in the world.
The Hong Kong International Airport at Chek Lap Kok is an example of "dredged" reclamation in which three-quarters of the airport platform was reclaimed from the sea using a combination of dredging mud from the seabed, borrowing marine sand, excavation of islands, and construction of seawalls.
Land reclamation - Salt Affected Soils, Reclamation Techniques, Benefits: In the arid regions of the world, and along coastal areas subject to periodic inundation by sea water, soils may have such a high content of soluble salts that production of economic plants is not possible. The salts found in soils are generally the chlorides, carbonates, bicarbonates, …
Hydraulic fill reclamation has become more common in recent times and land reclamation sites can be found all over the world. Uses of land reclamation. Whatever method is used to reclaimed land, it is usually part of a comprehensive project such as the construction or expansion of a port, of an airport, or of residential or commercial complexes.

SINGAPORE - Incinerated ash and other waste materials from Semakau Landfill could be used for reclamation works in the third phase of Tuas Port's development.
In most cases, the land used in land reclamation is typically compacted sand dredged from the nearby ocean. Thanks to millennia of erosion, sand on land, too …
Land reclamation can also impact ecosystem types, such as sand dunes or freshwater bodies, of coastal and terrestrial origin. Subsidence can be a concern, both because of topsoil erosion on flooded land and when wetlands are surrounded by levees and drained to produce polders (i.e., low-lying land retrieved from the sea or a river and …
Cambodia has permanently banned the export of sand, an agricultural product that has been used in land reclamation since the 1970s, and has ended sales to Singapore, which has used it for several years.
