As Greenland’s Ice Melts, Glacial Sand Deposits May Offer a Welcome Economic Opportunity – Columbia Climate School

Greenland’s glaciers grind rock into a fine powder that discolors meltwater and often makes beautiful patterns as it mixes with seawater.(courtesy of NASA Earth Observatory, by Joshua Stevens, using Landsat data from the U.S. Geological Survey. Public Domain).

Greenland’s ice sheet is losing 280 billion tons of mass per year, and some models suggest that its glaciers may be melting up to 100 times faster than expected. But flowing off those glaciers comes a potential economic boom: sand. Each season, millions of tons of sediment flow from melting glaciers into the ocean, adding landmass to the largest island in the world. According to a research paper published in Nature last fall, three out of four Greenlanders support extracting and exporting sand — so long as they’re the ones in charge of managing the resource…

Lost Lands: Mining the Mekong – the South China Morning Post Films

Cambodia’s appetite for sand has exploded as construction continues to fuel economic growth in the capital Phnom Penh. But as the thirst for sand grows, so does the uncertainty over the future of the river. Two families who rely on the river for a living share their stories of how sand dredging is causing pain and concerns for the future.

Beaches on Scotland’s ‘Hawaii of the North’ at risk after sand stolen – The Telegraph

With its stunning white crystal sands, it is known as “Hawaii of the North”. But beachcombers are said to be removing the famous sands of Tiree in the Hebrides on an industrial scale. Landowner Argyll Estates suspects sand is being “stolen” by “greedy” islanders under cover of darkness. Reports also suggest that it is “the more affluent residents” who are involved “so the reasons for this may not always be hardship but perhaps greed…”

The global impact of sand mining on beaches and dunes – Ocean & Coastal Management

Beaches and coastal dunes have always supplied sand for a wide range of uses, and initially the extracted volumes were limited to buckets, wheelbarrows, or small pickup truck loads. However, starting in the late twentieth century, and thanks to urban development, especially for coastal tourism, coastal and river sand has been extracted at an accelerated pace, and on a much grander scale…

Diamonds, zircon and other minerals have long been extracted in the sandy coastline near the Olifants river, which flows into the Atlantic about 300 kilometres (180 miles) north of Cape Town.

But plans to expand the mining have angered surfers, animal lovers and residents in this remote, sparsely populated region—and they are pushing back with lawsuits and petitions.

Mining the Mekong: Land and livelihoods lost to Cambodia’s thirst for sand – MONGABAY

“We would argue that sand mining is having as big, if not a bigger impact on the delta and Cambodian reaches. It’s been shown to be the biggest driver of saline intrusion in the delta, and resulting in enhanced bank erosion more so than hydropower,”

– Chris Hackney (University of Newcastle), Julian Leyland and Steve Darby (University of Southampton)

Why beach sand mining is so dangerous – Times of India

Beach sand mining has been illegal since 1991 when the Coastal Regulation Zone Rules were first notified thirty years ago. Although illegal mining on beaches has continued nevertheless, the scale has been comparatively lesser than in rivers, where it has devasted entire swathes of land and water. Major Indian rivers like the Ganga, Yamuna, Godavari and Kaveri face existential threat…

Illegal sand mining eroding Morocco’s coastline and tourism

Tourism is essential to Morocco’s economy, and its beautiful beaches are a vital part of the attraction for visitors. In an ironic Catch-22 situation, however, meeting the demands of this industry is indirectly destroying the very coastline that tourists are coming to enjoy.
