The International Conference 2021 (INAFOR 2021 Stream 2) was held on 7-8 September 2021 in a virtual format via zoom meetings due to the COVID-19 pandemic situation. It was conducted virtually to align with the biannual agenda of The 6th International Conference of Indonesia Forestry and Environment Researchers (INAFOR), which previously was carried out by The Agency for Standardization of Environment and Forestry Instruments, Ministry of Environment of Forestry, Indonesia. This is the first international conference hosted by The Center for Standardization of Sustainable Forest Management Instruments, Bogor, West Java, Indonesia. This conference was an important medium for sharing information and experiences and encouraging collaboration in sustainable forest management.The theme “Managing Forest and Natural Resources, Meeting Sustainable and Friendly Use”, strategically supports Indonesia’s commitment to Net Sink Forestry and Land Use (FoLU) 2030. The INAFOR 2021 Stream 2 was attended by approximately 750 participants, invitees, keynote speakers, scientists, and academicians from Indonesia, South Korea, the Netherland and Australia. The conference took place with a plenary session featuring six Keynote Speakers that presented exciting and practical information relevant to the theme. Also, a parallel session was divided into 12 separate zoom spaces according to the topics and number of participants. The presenters had ten minutes to present their papers and followed by interactive and engaging discussion.This proceeding presents 78 papers of research results on various topics, including biodiversity conservation, livelihoods, climate resilience, timber, and non-timber forest products. Those valuable pieces of information and recommendations can be modalities and references for the preparation and development of standards for sustainable forest management instruments and the development of science, technology, and innovation.Thank you.Dr. Wening Sri WulandariActing Director of Center for Standardization of Sustainable Forest ManagementInstruments Scientific Committee Prof. (Ris.)
