Review of Existing Sustainable Forest Management (SFM)-Based Projects in Indonesia

Rusolono, T. and Tiryana, T. 2011. Review of Existing Sustainable Forest Management (SFM)-Based Projects in Indonesia. Ministry of Forestry and International Tropical Timber Organization (ITTO), Jakarta. (in English and Indonesian)

Summary

Since the 13th climate change conference (COP 13) in 2007, sustainable forest management (SFM) has been considered as an option for reducing emissions through REDD+ mechanism. Such international agreement provides a great opportunity for Indonesia to highly involve in the REDD+ mechanism, because Indonesia has abundant forest resources. The REDD+ mechanism through SFM, however, needs to be further investigated because until now there is no real implementation yet. This study was aimed to review the progress of SFM practices and REDD+’s demonstration activity projects in Indonesia, to analyze several SFM scenarios for reducing emissions, and to formulate relevant strategies for reducing emission through SFM.
