IntroductionIn an era dominated by plastics (i.e., The 'Plasticene' Haram et al., 2020), where synthetic plastic materials and chemicals are pervasive in our daily lives, industries, natural environments, it is crucial to focus on addressing the underlying structural causes of marine pollution, particularly those affecting remote islands coastal communities global ocean. Conversely, within context Blue Economy transition, which emphasizes sustainable use ocean resources, integrating equity sustainability into development policies presents a key opportunity address systemic root pollution (Bennett 2023; Cisneros-Montemayor 2019; 2021; Simon 2021). Plastic production deeply intertwined with legacies colonialism persistence inequities, have shaped production, consumption, disposal (Liboiron, Fuller 2022). unchecked proliferation toxic wasteful plastics, driven monopoly capitalism influence powerful multinational corporations (Jacques, Mah, 2022), drives these disproportionately low-income historically marginalized (Vandenberg Ota, 2022; Vandenberg 2024). Ineffective inequitable waste management systems further entrench disparities. Thus, developing truly equitable just circular economy for necessitates critically examining institutional historical issues, ensuring that new do not perpetuate same inequities they seek resolve. An requires bold solutions eradicate while championing management, environmental justice, social equity.The governance literature increasingly recognizes as multidimensional concept includes distributional, procedural, recognitional, contextual dimensions, defined elsewhere (Croft 2024; Crosman Friedman 2018; Law Pascual 2014, McDermott 2013, Ota This call advancing approach emerges need challenge how approaches change often been developed alignment Eurocentric scientific academic theories methodologies. These lack direct meaningful engagement diverse plural forms knowledge, values, actions, practices other cultural groups, especially Global South, apply solve everyday socio-ecological challenges. Hegemonic research-to-action strategies tend be based partial limited design frameworks marginalize varied range knowledges on-the-ground actors essential advance partnerships collaborations more effective innovative knowledge-action initiatives change. In this context, role - aimed dismantle inequity inequality through oceans paramount importance (Crosman Ocean Nexus, doing so, interventions should recognize issues cause such colonial oppressions, racism, exploitative benefit already wealthy worsening poor, building up plans monitoring programs reverse (Ocean diversity heterogeneity knowledge value across different resource users require recognition existence both ontological plurality (diversity ways existing world) epistemic knowing world). collaborative must able accommodate representation provide spaces inclusive dialogue seats equal voices at table rightsholders representing all facets (Kovacs Pataki, 2016; Ludwig MacNaghten, 2020). important ensures perspectives stakeholders, rightsholders, holders, including directly affected it, included can tackle issue.A specific showcase study local foster socially equitable, environmentally sustainable, economically viable Galápagos Islands, crossroads facing changes because emerging cumulative multiple-anthropogenic stressors, complex Marine Reserve National Park (Alava Among human-made stressors impacting islands, contamination macro- microplastics) tandem (e.g., persistent organic pollutants mercury) unique marine-coastal ecosystems, endemic species, fishing heavily reliant seafood 2014; Alava Ross, Jones McMullen Muñoz-Abril Muñoz-Pérez Schofield A transition from traditional linear 'cradle-to-grave' system reduces leakage, embracing reduction, reusing, recycling, recovering via has suggested (Jones 2023); however, consequences social-ecological impacts implementing yet evaluated, introduction plastic— material locally sourced their communities' land.Aiming problem question identify potential resulting model resembles complicated challenge. only objectives better understand structure functions human communities), but also explore gaps implementation plastics' (Figure 1).
