It is estimated that, by 2050, the human population will jump to a
whopping 9.8 billion
[1]!

To house all of these people tons and tons of concrete, sand and other
aggregates will be needed. Currently for construction riverbed sand,
marine sand and manufacturing sand are used.

Dredging of riverbeds causes huge damage to the habitat, distorting aquatic ecosystems, leading to loss of biodiversity and soil erosion.

Once thriving sand beds, now stripped bare. Illegal sand mining has become the new deforestation.

Karnataka, a southern state in India, recorded over 1000 illegal sand mining cases in the last three years, with 20,779 cases registered between 2015 and 2018 [2][3].

Illegal sand mining cases in North Karnataka, which have devastated rivers, have gone up from 4,402 in 2022-23 to 5,441 in 2023-24.
In the state of Tamil Nadu alone, the loss of revenue from illegal riverine sand mining is estimated at around $2.7 billion, highlighting the economic implications of unregulated extraction practices [4].
The illegal sand mining sector is worth $126 billion annually, employing 35 million people in India alone, with a global trade value of $70 billion driven by construction demand [4].
