Riverbed Mining• It is a practice that is used to extract sand,

mainly through an open pit made in the river beds

• Reasons:– Used as an abrasive– Construction activities– Replace eroded coastlines– Extraction of minerals such as rutile and zircon

which contains industrially useful elements such as titanium and zirconium

– Glass making

Page 3: Riverbed mining - Rajasthan

Problems Associated

• Erosion• Impact on local wildlife– Example : Near extinction of Gharials

• Disturbance of underwater sand causes turbidity in the water, which is harmful for such organisms that need sunlight.

• Destroys Fisheries: – causing problems for people relying on fishing for a

living

Page 4: Riverbed mining - Rajasthan

Terms Of Reference (TOR)

• TOR for Environmental Management Plan (EMP) for “Mining of Minerals” as per the EIA Notification 14th September 2006 are prerequisites for obtaining Environmental clearance

• Terms of Reference provide guidance and direction to the project proponent for planning and designing of EIA
