Dredge mining environmental impact9/8/2023 Now Chinese dredgers are scooping up sand from Poyang Lake. But so damaging was the dredging that it has been banned. In the past, it has mainly been dredged up from the Yangtze River. Studies of the environmental impact caused by lake and river dredging in other parts of Asia unquestionably prove this point.Ĭhina’s growth is based on its ability to get large quantities of construction sand, and this building sand must come from somewhere. While it claims that it will stop dredging operations should it become clear that environmental damage is in fact being done, our river eco-systems cannot avoid this kind of devastating damage because by definition to dredge is to damage. ![]() The government will also be making a hefty profit by selling the dredged sand to Maldives and Singapore. The purpose is to clear river channels for shipping lanes. This is what will be happening soon in Bangladesh, now that the government has decided to undertake long-term dredging operations in the Jamuna River. But as these cities go up, the natural environment around them suffers. Sand – a necessary part of making concrete used extensively in the construction industry – helps build the cities of tomorrow. Vulnerable riverbeds, shorelines and even fresh water lakes are being damaged by sand dredgers across the world.
