The decimation of the Sundarbans has resulted from attempts to satisfy short-term demands by exhausting the chances of satisfying future demands. The forest cannot be preserved by a policy that under-valorizes the urgency of the short-term needs or by a policy that is imposed from above, but it may be by social forestry. Social forestry augments the supply of forest products from non-forest lands, and, most significantly, includes the users in developing appropriate forest policies.
