The Mullaperiyar agreement, signed between the governments of Tamil Nadu and Kerala in 1886, has been a contentious issue between the two states for several decades. The agreement allows the Tamil Nadu government to operate the Mullaperiyar dam in Kerala, which supplies water to the state of Tamil Nadu.

In recent years, the issue has gained significant attention, with both states demanding a renewal of the agreement. The Kerala government has been raising concerns about the safety of the dam and has been demanding a new agreement that addresses these concerns.

The Mullaperiyar dam is located in the Periyar National Park in Kerala and is one of the oldest dams in India. Kerala has been advocating for the construction of a new dam, citing safety concerns regarding the current structure. The state has also raised concerns about the water-sharing agreement, which it claims is unfair and should be revised.

On the other hand, Tamil Nadu argues that the dam is safe and that the water-sharing agreement should not be altered. The state relies heavily on the water supplied by the Mullaperiyar dam and has been unwilling to compromise on the issue.

The Mullaperiyar agreement renewal has become a highly politicized issue, with both states accusing each other of acting in bad faith. The two states have been unable to reach a consensus on the issue, which has led to several rounds of litigation in the Supreme Court.

Despite the legal battles, the issue remains unresolved, and the two states are yet to come to a mutually agreeable solution. The central government has also been involved in the matter, attempting to mediate between the two states to find a resolution that is acceptable to both parties.

In conclusion, the Mullaperiyar agreement renewal remains an unresolved issue between the states of Tamil Nadu and Kerala. The safety concerns of the dam and the water-sharing agreement continue to be contentious issues, and it remains to be seen if the two states can come to a mutually agreeable solution. The issue highlights the need for effective cooperation and communication between states to address shared resources and resolve conflicts.
