Climate-driven coastal displacement reshapes marine ecosystems: How colonial-era species transport and neoliberal port expansion amplify invasive biodiversity crises
Original framing: “Invasive marine species set to take advantage of rising seas” — Phys.org
Shrimp farmers in Vietnam’s Mekong Delta, displaced by Asian tiger shrimp monopolies, describe the species as *‘thieves of livelihoods’*—a framing absent from academic discourse. The 2021 *Ocean & Coastal Management* study found that 70% of coastal laborers in Southeast Asia blame 'invasive species' for job losses, yet their protests (e.g., 2019 Philippines shrimp farmer strikes) are framed as 'anti-development' rather than structural critiques. Women-led fishing cooperatives in India’s Sundarbans report that non-native tilapia species, introduced for aquaculture, have altered gendered labor divisions, yet these impacts are excluded from policy debates dominated by male scientists and port executives.
The 'invasive species' crisis is not a natural disaster but a **colonial-ecological feedback loop**, where 19th-century ballast water trade and 20th-century port expansion created the conditions for non-native dominance, while 21st-century climate migration policies and coastal militarization accelerate the collapse.
The framing obscures how Indigenous fire and flood management (e.g., Mi’kmaq clambaskets, Yolŋu rangers) could mitigate this crisis if revived, and how marginalized voices—like Vietnamese shrimp farmers or Māori guardians—offer solutions rooted in relational ecology rather than top-down control. The trickster crab, thriving in the chaos of human disruption, exposes the absurdity of culling programs that ignore the real 'invader': the neoliberal port economy turning coastlines into species highways. To break this cycle, power must shift from corporate port operators and Western scientists to Indigenous stewards and coastal laborers, who demand **ecological reparations** for historical introductions and **polycrisis-resilient MPAs** that treat species as participants, not problems.
