Diagram
- National perspective plan - Interlinking of 30 Rivers - 16 Himalayan - 14 Peninsular - Formation of monitoring committee

Benefits (1) Provide water to water scare region eg Bundelkhand through Ken - Betwa → Benefit 6 mn people (2) Helps in disaster management (2) Transfer of water from ken to Betwa reduces flooding (3) Hydroelectric potential - estimated at 36,000 MW by NRLP. (4) Agriculture Benefit → Increases irrigated area → canal = cheap source of irrigation (5) Helps in water connectivity and development of waterways. (6) Storage capacity ensures less flow to Ocean and less wastage

Social Concern (1) Displacement of 1 lakh people (80% Tribal) due to Ken - Betwa project (2) Disproportionate impact on vulnerable section (3) Rural areas more affected while urban are insulated

Economic Concern (4) High cost - As per NRLP, 30 rivers would cost Rs 5.6 lakh crore. (5) unviability of energy → due to high cost of extraction

Environmental Concern (6) faulting & Blasting → seismic risk (7) Submergence of critical habitat eg Panna Tiger Reserve (8) Wildlife habitat fragmentation eg Tigers.

Thus, proper EIA and Social Impact Assessment (SIA) needs to be done to ensure feasibility.
