Indigenous Wisdom for Indonesia’s Sustainable Ocean Economy

Indonesia is integrating centuries-old Indigenous fishing practices into its national Blue Economy Roadmap, a strategy designed to balance maritime economic growth with ocean health. The initiative focuses on incorporating traditional methods of marine resource management, particularly the “Sasi Laut” system practiced by coastal communities in the Maluku and Papua islands.

Sasi Laut, meaning “sea customs,” involves temporary, community-determined fishing closures – typically lasting six to twelve months – to allow marine species like sea cucumbers and shellfish to replenish their populations. Unlike conventional, top-down conservation efforts, Sasi Laut operates through collective decision-making within local customary institutions, which determine closure periods, protected species, and harvest timing. This community control serves as a barrier against large-scale commercial exploitation, effectively preventing the privatization and industrialization of marine resources.

A recent study published in Marine Policy found a strong alignment between these Indigenous practices and Indonesia’s Blue Economy Roadmap 2023. The roadmap aims to harness the potential of ocean resources although ensuring the long-term sustainability of marine environments. By integrating Indigenous knowledge, Indonesia hopes to promote responsible fishing practices and enhance the resilience of its marine ecosystems.

The integration of Indigenous practices is seen as crucial for fostering a sense of ownership and stewardship over marine resources, according to stakeholders. The approach prioritizes the conservation of fish stocks, the protection of critical habitats, and sustainable harvesting techniques. However, researchers caution that temporary closures alone may not be sufficient to address all modern fishing pressures.

Indonesia adopted its Blue Economy Roadmap in recent years, but faces challenges in implementation, particularly concerning modest-scale fisheries and the recognition of Indigenous knowledge. The success of Sasi Laut demonstrates the potential for traditional ecological knowledge to complement contemporary conservation strategies, offering a sustainable alternative to purely commercial approaches to ocean resource management. The system’s effectiveness relies on established communities with recognized control rights over their waters.
