We Are Running Out of Sand

HughPickens.com writes John R. Gillis writes in the NYT that to those of us who visit beaches only in summer, beaches seem as permanent a part of our natural heritage as the Rocky Mountains but shore dwellers know that beaches are the most transitory of landscapes, and sand beaches the most vulnerable of all. Today, 75 to 90 percent of the world's natural sand beaches are disappearing, due partly to rising sea levels and increased storm action, but also to massive erosion caused by the human development of shores. The extent of this global crisis is obscured because so-called beach nourishment projects attempt to hold sand in place (PDF) and repair the damage by the time summer people return, creating the illusion of an eternal shore. But the market for mined sand in the U.S. has become a billion-dollar annual business, growing at 10 percent a year since 2008. Interior mining operations use huge machines working in open pits to dig down under the earth's surface to get sand left behind by ancient glaciers.

One might think that desert sand would be a ready substitute, but its grains are finer and smoother; they don't adhere to rougher sand grains, and tend to blow away. As a result, the desert state of Dubai brings sand for its beaches all the way from Australia. Huge sand mining operations are emerging worldwide, many of them illegal, happening out of sight and out of mind, as far as the developed world is concerned. "We need to stop taking sand for granted and think of it as an endangered natural resource," concludes Gillis. "Beach replenishment — the mining and trucking and dredging of sand to meet tourist expectations — must be evaluated on a case-by-case basis, with environmental considerations taking top priority. Only this will ensure that the story of the earth will still have subsequent chapters told in grains of sand."

      Beach restoration very rarely works on a timescale longer than a few years. Beaches are very dynamic environments, with sand flowing into them, along them and then off them. Most losses of beaches are not because (directly) of sea-level changes, but because the supply of sand has been interrupted somewhere upstream (and that can take decades to become visible, and decades to correct). whether that is because of dredging of the sand upstream for some industrial purpose, or re-alignment of a river (there are huge problems around the Mississippi delta, for example, because they're being sediment-starved because of the building of levees to protect New Orleans. Make a choice : New Orleans, or stable shore lines?), or changes in agricultural practice in the feeding rivers, or dams that trap the sand hundreds of kilometres from the coast.

      That's why (shock, horror) government agencies try to insist upon environmental impact assessments of developments before they happen, and is also why business people who want to make those developments without paying the costs of the changes they make resist those regulations.

      Actually, it's not just businesses that cause the problems. In the mid-1950s there were significant mileages of coastal defences built along parts of the East Coast of England and the coasts of the Low Countries, by governmental agencies, in response to a flood/ storm surge in 1953 which was comparable to the Katrina hurricane in New Orleans. Over the subsequent decades it has been realised that many of these schemes have been poorly designed (because rushed into construction, because "do something!") and are causing further erosion and often retreat of the sea front, because of changes to sediment movement. It took less than two decades to realise and understand the problems, but more than four decades to even partly repair the consequences. That's while also dealing with around 3.5mm/yr of isostatic sea-level rise and another ~2mm/year of eustatic (global) sea-level rise.

      There are genuine and real issues in managing coastal change - and coasts are changing, all the time. Regardless of the arguments about the reality of global warming (as a geologist, we've no doubt that it's happening, and little doubt about the rates and medium-term consequences), in large parts of the world there is continuing isostatic re-adjustment to the melting of the glaciers, even out to around a thousand kilometres from the ice front, because the rock for the uplift of glaciated areas has to come from somewhere. Moving further from the glaciers, to for example the Mediterranean, the whole area is tectonically active enough to have many metres of vertical movement within recorded history (see, for example, Lyell, 1832-6 describing the "Temple of Seraphis" near Naples, https://en.wikipedia.org/wiki/...). I don't know the geology of southern America well enough to know what;s happening there, but anywhere north of one or other Carolina you're going to be getting into isostatic effects.

      Regardless of which, the premise of the author - that only beach sand matters and only beach sand is measured is pure bullshit. The amounts moved around for beach restoration and other cosmetic purposes is vanishingly small compared to the (mega-)tonnages used in the building industry as aggregate for making concrete. Just because people see it, doesn't mean that it's particularly important. Would you prefer to have no concrete, anywhere, and a nice beach?

    Studied some oceanography. The problem is not that beaches are transient. The problem is our idea of property. The problem is ports, seawalls, jetties. We want beach front property we can have a house on, a hotel on, a strip mall by. You can repair a beach. Just quit building within a few miles of it. It's a moving object. It will show back up once you give it the proper habitat. If you build houses and seawalls up the entire coast you will not have beaches. That means the beach disappears. The natural mechanisms that make beaches cannot do their jobs.

  32. Ecological Dangers? by decibel.places · · Score: 2

    Are we going to disrupt global ecology further for tourism and industry?
    1. Beach erosion is a natural effect from rising sea levels. We can only interrupt this process for a limited time, until sea levels make it impossible to replenish the sand. And what are the ecological consequences of interfering with this porcess?
    2. Exporting large amounts of sand from one place to another disrupts the ecology of the location being mined. It can interfere with the way water and light are handled by the landscape. Certainly it has an impact on the local flora and fauna.
    3. If Silicon Valley needs more sand, let them get it from the moon. Don't further damage our global ecology for industry.
