''Multi-purpose projects and large dams have been the cause of many new social movements.''Highlight the concerns related to such movements.

Hint: Multi-purpose dams are typically used to combine hydropower through water turbines and storage of water for irrigation or water supply.

Complete answer: The development of multi-purpose projects and large dams cause the removal of large areas of forests and lands that is promoting deforestation and in turn global warming. That is why it has been the cause of many new social movements. Due to the lack of rehabilitation centers for people who have been displaced due to these reasons is becoming a reason of concern for the society. Displaced families have to adapt to a lot of different situations with no help at all. The financial cost that comes with the development of such projects, if used judiciously, can do alot of good to the needy people of the country and states.
Multi-purpose dams are typically used to combine hydropower through water turbines and storage of water for irrigation or water supply. A feature with a flood-control function to prevent rise in the level of rivers is also common in flood-prone areas.
Beas Project is a joint venture by the governments of Punjab, Haryana and Rajasthan to create a multi-purpose dam for the development of their states. It consists of two main units: Beas-Sutlej Link and the Beast Dam at Pong. The project links the Beas river and the Sutlej rivers in Punjab along a 38.4 km long valley of hills.

Note: Chambal Valley Project is also a joint venture undertaking by the governments of Rajasthan and Madhya Pradesh. It is made on the Rana Pratap Dam at Bhata which is 48 km from Kotah. It was inaugurated on Feb 9 in 1970. The project comprises construction of two more dams that are: the Gandhi Sagar Dam present in Madhya Pradesh and the Jawahar Sagar dam present in Rajasthan.
