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?
The four-main stakeholders have been discussed in this chapter- 1. People who live in the forest are dependent on the forest produce for various aspects of their life. 2. The forest department of the government which owns the land and controls the resources from the forest. 3. The industrialists- from those who use ‘tendu’ leaves to make bidis to the ones with the paper mills- use various forest produces, but are not dependent on the forests in any one area. 4. The wildlife and the nature enthusiasts who want to conserve nature in its pristine form.
Among all four stakeholders, the forest department of the government should have the authority to decide the management of forest produces because the forest department is the caretaker of the land used in forest, controls the resources from the forest and this forest department is responsible for any damage to the forest.
