Over-exploitation has led to the aggregate reserves in the Pankuruma river area in Sipe Sipe, Bolivia, running out. According to local reports, workers are now extracting sand and stone from new areas in Capinota and Santivanez, despite doubts over whether the correct environmental licences have been obtained.
The aggregates are being supplied to a giant railway project in Cochabamba, and authorities in the area are considering whether or not to halt all extraction rights in the Pankuruma are before the end of October.
Asociacion Mixta de Proveedores de Agregados del Valle Bajo (Amavab) has stated that it is looking for different options and that it wants to find new ways to continue supplying aggregates to the rail project, with Santivanez looking like the best alternative.
Five new areas for extraction including Viloma, Pirhuas, Siquia Siquia, Chahurani and Combuyo are being investigated.
