“Hawaii’s famed Waikiki Beach started to erode again, less than a year after the completion of a $2.2 million project to replenish the sand on about 1,730 feet of shoreline that had been suffering from chronic erosion.”Captions.
“Development is absolutely responsible for the majority of the beach nourishment,” Andrew Coburn, assistant director of The Program for the Study of Developed Shorelines at Western Carolina University, said. “Well over 99 percent of the shorelines that are nourished are developed so there is some economic value placed behind them.”

Excerpts;

While sand mining is not illegal here, some community members are concerned about the resource being depleted and shipped off-island and archaeological damage.

Mayor Alan Arakawa is among the concerned, saying the sand is needed for Maui projects and replenishing beaches.

He asked the council to revisit a 2006 study, which showed a five- to seven-year lifespan on inland dune sand if mining continued at the 2006 pace. It is time to consider a moratorium on sand exports because it is not a renewable resource..

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 Wars” film documentary by Denis Delestrac – first broadcasted on the european Arte Channel, May 28th, 2013, where it became the highest rated documentary for 2013 – expressly inspired the United Nations Environment Programme (UNEP) to publish this 2014-Global Environmental Alert.

    Quick sand, dirty Money; South Africa

    December 6th, 2017

    Mining has already cut coastal sand supply by as much as 70 percent in the municipality of Ethekwini, which includes Durban. Each year, miners dig up more than 400,000 cubic meters of sand from Durban’s rivers, enough to fill 160 Olympic swimming pools. This sand would normally be deposited on beaches and help offset coastal erosion. At current mining rates, Durban’s beaches are predicted to contract, on average, by more than a meter each year.
