The shortage of sand from riverbeds is going to grow, warns the natural resources development corporation (NRDC). This alarm comes when construction owners are already facing an acute shortage of riverbed sans, which is considered better in quality. NRDC believes that, with the increase in construction activities and Punatsangchhu I taking off, the shortage will be felt more acutely. According to NRDC officials, the shortage of sand was created because customers stopped using sand from Phuentsholing because of the drastic reduction in sand price at depots in Punakha and Wangduephodrang.
