The given statements about the Compensatory Afforestation Fund Management and Planning Authority and the Compensatory Afforestation Fund Act, 2016 are as follows:

As per law, the Compensatory Afforestation Fund Management and Planning Authority exists at both National and State levels.

This statement is correct. The Compensatory Afforestation Fund Management and Planning Authority (CAMPA) exists at both National and State levels. At the National level, it is called the National Compensatory Afforestation Fund Management and Planning Authority (NCAFMPA) and at the State level, it is called the State Compensatory Afforestation Fund Management and Planning Authority (SCAFMPA).

People’s participation is mandatory in the compensatory afforestation programmes carried out under the Compensatory Afforestation Fund Act, 2016.

This statement is incorrect. The Compensatory Afforestation Fund Act, 2016 does not mandate people`s participation in the compensatory afforestation programmes. However, the Act does provide for the involvement of local people in planning and execution of afforestation and related activities, and also for sharing of benefits arising out of these activities with them.

Therefore, the correct answer is option A - 1 only.
