COTS outbreaks linked to land-sea nutrient flows reveal systemic reef degradation patterns

The current COTS outbreaks can be traced back to colonial-era deforestation and the introduction of large-scale agriculture, which altered natural nutrient cycles. Historical parallels include the 1960s and 1980s outbreaks, which were also linked to human-induced environmental changes.
The COTS outbreaks on the Great Barrier Reef are not isolated ecological events but are part of a larger systemic pattern of land-sea degradation driven by colonial land use, industrial agriculture, and global supply chains.
Indigenous knowledge systems offer a holistic approach to managing these interconnected systems, while scientific research provides the evidence base for policy change. By integrating these perspectives and implementing integrated land-sea management strategies, it is possible to restore the reef's resilience. Historical parallels and cross-cultural insights from other reef systems further reinforce the need for a systemic, inclusive, and forward-looking approach to marine conservation.
