RATIONAL SCALING IN AQUACULTURE DEVELOPMENT: SCALING OUT, NOT ONLY UP

Aquaculture facilities of high capital intensity and large demands for space have a risk of disconnection from communities, especially in rural areas. Here, scale becomes not merely technical and economic variables but social-political ones, as all the impacts of scaling are not comprehensively addressed. Scaling requires recognizing the complexities (time, different investment types, etc.) involved in facilitating a transition to a new normal, and aquaculture, as a "new" intervention in most of the world outside of Asia, requires systemic, not simplistic, scaling strategies. Overhyped scaling-up narratives can attract capital prematurely, ignore ecosystem and social limits, and undermine credibility if failures occur.

Conventional scaling up assumes that a successful pilot can be replicated elsewhere, that increasing size equals success, and that technical solutions can simply be transferred. Controlled, pilot project environments don't always scale up. Pilot projects often rely on external funding, high-level technical, often-imported, leadership, and temporary incentives/subsidies. Such conditions do not represent real-world complexity. Many pilots fail because markets are not ready, governance is not aligned, and producers lose sustained incentives/subsidies. Smaller, economically viable aquaculture farms located in rural areas are more manageable, involve less risk, and produce less wastes, allowing integrated landscape designs for wastes as additional income sources in circular bioeconomies in contrast to mega-farms. Scaling up production without scaling value chains is unstable. Improper planning for scaling up can increase ecological impacts, concentrate economic power leading to even greater income disparities, marginalize small-scale producers, outpace governance capacity, and create social opposition. We suggest that aquaculture development not only consider scaling up growth in size or production output but also consider all scaling options to move toward strategies that embed ecological limits, social legitimacy, participatory governance, capacity building and institutional learning as the core tenants of sectoral expansion.

Scaling Out Strategies: Aquaculture Ecotourism

There is a path of rational scaling rarely considered in aquaculture development by governance systems or investors - scaling out - not only scaling up (Figure). Scaling out strategies emphasize partnerships for well developed models at scale, replication, institutional diffusion, stakeholder and governance alignment rather than simple size and production expansion. Scaling out requires inter-sectoral partnerships who develop economically viable, smaller scale aquaculture models that can be distributed widely over diversified ecologies and networks. Tourism contributes ~10% of global GNP. Aquaculture ecotourism is one practical way to add value to aquaculture without necessarily scaling production volume, as it has similar network diversity, attention to value addition, and branding. Aquaculture ecotourism is most compatible with experiential, nature-based tourism. Aquaculture ecotourism (farm visits, participatory monitoring, food experiences, place-based narratives) creates new interfaces among producers, communities, scientists, educators, policymakers, conservation NGOs, and consumers. Its main benefits are: (1) Income diversification and creation of local, mostly rural, jobs via farm tours, tastings, festivals, snorkeling/diving, and education experiences that diversify and create new revenue streams and employment that can buffer farmers from commodity price swings and create multiplier economies for communities; (2) Strengthened local food systems (shorter value chains) by creating "eat local" demands and premium pricing for traceable seafood, helping farmers and communities capture more value locally rather than exporting it. Culinary/food tourism strengthens inter-sector linkages, learning, and local economic development; (3) Increased social license and environmental stewardship in rural areas by making production visible and accessible, improving understanding and acceptance when farms are well-managed, and providing an educational and partnership platform for monitoring (citizen science), biodiversity, and conservation practices. Research has shown that increasing and diversifying stakeholder engagement is central to aquaculture's social acceptability. Partnerships with local academia and technology providers to develop transparent, accessible monitoring platforms can turn farms into living labs and field classrooms, another way to scale out benefits beyond production.
