AbstractManagement of forest resources is a major problem area in developing countries. Basing discussion of the problem on the situation in India this article recognizes the importance of a rational pricing policy but also argues that forest administration has to be strengthened. Regeneration of forest resources has to be stimulated by price improvements and encouraging investment but regeneration and rural development involving social and agro forestry are also required. Forest administration has to be developed to cope with these different requirements. The article questions the argument concerning institution building for development forestry advanced by Guess (1982).
