EXTRACTION and lifting of sand from river banks are quite common in our country. But in recent years sand mining from different rivers has become a matter for concern as this is causing collapse of banks. In the rainy season, the situation becomes worse as river banks become more vulnerable. Sand can be profitably extracted under a plan that is based on study of river flow dynamics. According to experts, sand mining from river beds can be very dangerous without carrying out prior studies. Unplanned and excessive sand mining causes degradation of rivers. Mining lowers the bed below normal levels, which may lead to bank erosion. Depletion of sand causes deepening of rivers, and enlargement of river mouths. Despite repeated warnings by the media, the government is yet to take any effective step to stop sand lifting.
Rivers are our national resources. It is imperative for us to protect them and bring the unauthorized sand traders under law and award them exemplary punishment so that nobody dares to do the same in future.
