Key facts
- The sasi system, a traditional Indonesian method of ocean management, has been practiced for over 400 years.
- Sasi involves temporarily closing specific marine areas to fishing to allow ecosystems to recover.
- This practice aligns with modern conservation principles by including timed fishing bans and community enforcement.
- Scientists are increasingly recognizing the effectiveness of sasi in rebuilding marine life and protecting coral reefs.
- The revival of sasi highlights the importance of local community involvement in successful conservation efforts.
For over four centuries, coastal communities in eastern Indonesia have employed a traditional system known as sasi to manage their marine resources. This practice, predating modern conservation efforts, involves temporarily closing off specific areas of the sea, including coral reefs and shellfish zones, to fishing and harvesting. After a designated rest period, these areas are reopened for controlled collection, allowing marine life to recover and populations to rebuild.
Researchers like Ingvild Harkes and Irene Novaczek have documented sasi as a customary rule system deeply embedded in local culture and governance, particularly in regions like Maluku and Papua. The system naturally incorporates principles such as seasonal fishing bans, community-led enforcement, and the protection of breeding cycles, which closely mirror contemporary marine conservation strategies. This indigenous approach, developed through lived experience and observation of natural patterns, provides marine ecosystems with crucial recovery time.
