We saw in this chapter that there are four main stakeholders when it comes to forests and wildlife. Which among these should have the authority to decide the management of forest produce? Why do you think so?SOLUTION:
Ans.: The people who live in and around forests should be given the authority to decide the management of forest produce because these people are living in forest areas from centuries.
