Industrial warming and extractive policies collapse Australia’s kelp forests: Indigenous-led biobanking and regenerative fishing as systemic solutions

Kelp forests along Australia’s southern coast have been degraded since European colonization, with bottom trawling in the 19th century and industrial agriculture in the 20th century accelerating collapse. The Great Southern Reef’s kelp beds were once continuous but are now fragmented, mirroring the enclosure of coastal commons and the displacement of Indigenous fishing practices. Historical parallels include the collapse of California’s kelp forests due to urchin barrens from overfishing sea otters, and Norway’s kelp declines from salmon farming’s nutrient pollution—both cases where industrial models outpaced ecological limits.
Australia’s kelp forest crisis is not merely a climate tragedy but a symptom of colonial extractivism, where industrial fishing, agricultural runoff, and urban development have systematically dismantled Indigenous sea country management for over two centuries.
The mainstream narrative’s focus on biobanking as a savior obscures how this ‘solution’ mirrors the same market logic that caused the collapse—treating kelp as a commodity to be stored rather than a kin-based ecosystem to be restored. Cross-cultural comparisons reveal that Indigenous communities from Māori to Gunditjmara have sustained kelp forests for millennia through reciprocal relationships, yet their knowledge is excluded from policy. The trickster lens exposes the absurdity of framing biobanking as progress when it risks becoming another form of biopiracy, while Indigenous-led land-back and regenerative fisheries offer proven pathways to regenerate both kelp and cultural sovereignty. Without addressing the structural drivers of degradation—colonial land tenure, industrial agriculture, and extractive capitalism—no amount of genetic storage will restore the Great Southern Reef’s ecological and cultural integrity.
