Southern States Clash Over Long-Running Water Disputes
Southern Indian states met to discuss problems involving shared rivers and dams.
Amit Shah asked the states to cooperate more closely.
However, the state leaders mainly repeated their long-standing demands.
Kerala wants the Mullaiperiyar dam removed, while Tamil Nadu depends on water from it.
Karnataka wants to build a dam at Mekedatu on the Cauvery River.
Tamil Nadu fears that the project could reduce the water reaching its territory.
The states have also disagreed for years about following court and tribunal decisions.
The meeting showed that solving these water disputes remains difficult.
Amit Shah urged greater cooperation among southern state governments at the Southern Zonal Council meeting.
Kerala renewed its demand to demolish the more than 120-year-old Mullaiperiyar dam supplying water to Tamil Nadu.
Karnataka continued backing a new Mekedatu dam on the Cauvery, while Tamil Nadu opposed the project.
Tamil Nadu called for compliance with court rulings and tribunal decisions on interstate water sharing.
Shah said the Council had resolved 1,445 of 1,869 interstate disputes raised since 2014.
