As of 2011-2012, when investigative filmmaker Denis Delestrac and team, were first collecting and unveiling sand mining datas and information from the professionals involved, they found and reported that “the Sand business was estimated to be a $70 billion industry, worldwide…! Sand is the second most consumed natural resource, after water. The construction-building industry is by far the largest consumer of this finite resource.” .

Excerpts;

We are astounded to discover there are more stars in the universe than grains of sand on our beaches.

Sand is in short supply and scientists have discovered the way we keep track of this resource has given us misleading information.

“Not all sand is the same,” said Associate Professor Ana Vila-Concejo from the University of Sydney School of Geosciences. “Yet the models for assessing sand and how it moves mostly rely on one type. This means we have an inaccurate picture of what is happening, especially in coastal areas that are vulnerable to climate change…”

Rising demand for sand calls for resource governance, UNEP; (05-07-2019)
With the global demand for sand and gravel standing at 40 to 50 billion tonnes per year, a new report by UN Environment reveals that aggregate extraction in rivers has led to pollution, flooding, lowering of water aquifers and worsening drought occurrence.

Demand for sand: the largest mining industry no one talks about; Inhabitat (05-23-2019)
The world’s largest and perhaps most destructive mining industry is rarely discussed. Approximately 85 percent of all material mined from the earth is a simple and widely available resource: sand. Because it is so cheap and readily available, it is mined by everyone from guy with a shovel, to multi-million dollar machine operations.

A looming tragedy of the sand commons; Science (09-08-2017)
Because of the difficulty in regulating their consumption, common-pool resources are prone to tragedies of the commons as people may selfishly extract them without considering long-term consequences, eventually leading to overexploitation or degradation. Even when sand mining is regulated, it is often subject to rampant illegal extraction and trade…

Sand, Rarer Than One Thinks: A UNEP report (GEA-March 2014)
Despite the colossal quantities of sand and gravel being used, our increasing dependence on them and the significant impact that their extraction has on the environment, this issue has been mostly ignored by policy makers and remains largely unknown by the general public.
In March 2014 The United Nations released its first Report about Sand Mining: “Sand, Rarer Than One Thinks.”
“Sand Wars” film documentary by Denis Delestrac – first broadcasted on the european Arte Channel, May 28th, 2013 in its french version: “Le Sable: enquête sur une disparition”, where it became the highest rated documentary for 2013 – expressly inspired the United Nations Environment Programme (UNEP) to publish this 2014-Global Environmental Alert.

Sand Is in Such High Demand, People Are Stealing Tons of It, By Dave Roos; HowStuffWorks (03-06-2017)
As strange as it may sound, sand is one of the world’s hottest commodities. The global construction boom has created an insatiable appetite for sand, the chief ingredient for making concrete. The problem is that sand isn’t as abundant as it used to be. And when high demand and high value meets scarcity, you open the doors to smuggling…
