1.
Interlinking of rivers as an adaption strategy to address the impact of climate change on water resources
Sustainable Lifestyle = Positive Climate Action

2.
Issues and Challenges
• Seasonal and Temporal variation in Water Availability
Most of the Rainfall taking place 3-4 months of monsoon
Wide variation in water availability among basins and regions.
• Recurring Floods in some areas and droughts in some
• Increase in water demands for various sectors for needs of ever rising population
Likely impacts of climate change

Inter-linking of Rivers
•Response to Climate Change
Increase in global temperature
With Expected increase in rainfall intensities and shorter durations, the Storages created for ILR will be useful in storing water in such an eventuality
Useful both for floods and drought management.
Will benefit all the inter-connected Basins including the donor basins

12. Inter-linking of Rivers
Inter-linking of Rivers
•Response to Climate Change
Decrease in global temperature
Transfer is being planned on huge monsoon surpluses and not on snowfed surpluses from Himalayan Rivers.
Flow during non-monsoon is adequate for the demands of the basin itself.
But if the snow contribution is reduced the storages created will be beneficial for the basin itself.
Based on water availability in connected basins, water can be judiciously utilized in both the basins.
