How the exam will ask it
ପ୍ରିଲିମ୍ସ
- Bihar has announced India's first comprehensive State-level silt management policy.
- The National Highways Authority of India (NHAI) plans to use river silt as highway construction material.
- Using river silt can reduce dependence on mined earth for embankments and road formation.
ମେନ୍ସ
GS3 (Environment, Disaster Management): Siltation in rivers such as the Kosi and Ganga reduces channel capacity and worsens floods in Bihar. A State silt management policy combined with NHAI's reuse of silt in highways turns a hazard into a resource and cuts earth mining. The way forward lies in scientific desilting, ecological safeguards, and basin-level coordination with upstream States and Nepal.
