KOCHI: The All-Kerala River Protection Council has demanded the Constitution of River Protection Authority to save the rivers and water resources in the state where different lobbies were engaged in activities causing harm to most of the rivers. The council alleged that most of the rivers in the state were being misused by the agents of building industry, sand mafia and river encroachers. It was high time for the government to act for protecting the rivers, the council said in a meeting. The Council welcomed the Centre's Kuttanand package, but expressed concern over the state government's slow pedaling over the implementation of it. The council in its meeting decided to celebrate the river day on the banks of Chalakkudi River on October 3.
