A nation built on sand Nepali Times
Nepal produced 13.5 million metric tonnes of cement in the 2019/20, for which it needed 90 million tonnes of sand and gravel that year. Nepal’s self-sufficiency in cement production has meant that mining industries extract 13 million tonnes of limestone — for which the government collected royalty worth Rs790 million during the last fiscal year.But in Nepal exactly a week earlier, the government in its budget for the fiscal year 2021-22 that begins in mid-July said that it would allow the export of stones, pebbles and sand from across the country to decrease the trade deficit.

Sand mining: how it impacts the environment and solutions
Sand mining from rivers and marine ecosystems " can lead to erosion, salination of aquifers, loss of protection against storm surges and impacts on biodiversity, which pose a threat to livelihoods through, among other things, water supply, food production, fisheries, or to the tourism industry," says UNEP. In 2018, the World Wildlife Sand mining from coastal and marine areas is another source, although less preferred as it requires specialized equipment and the salt must be rinsed from the sand and gravel prior to use, thus increasing costs (Koehnken and Rintoul, 2018; Gronwald et al., 2020).This mass extraction has significant infrastructural impacts and social costs Sand mining: Stopping the grind of unregulated supply chains
