Disentangling global market drivers for cephalopods to foster transformations towards sustainable seafood systems

[摘要] 1. Aquatic food systems are important contributors to global food security to satisfy an intensifying demand for protein-based diets, but global economic growththreatens marine systems. Cephalopod (octopus, squid and cuttlefish) fisheriescan contribute to food security; however, their sustainable exploitation requiresunderstanding connections between nature's contributions to people (NCP), foodsystem policies and human wellbeing.2. Our global literature review methodology examined what is known about cephalopod food systems, value chains and supply chains, and associated market drivers. For analysis, we followed the IPBES conceptual framework to build a map ofthe links between cephalopod market drivers, NCP and good quality of life (GQL).Then we mapped cephalopod food system dynamics onto IPBES (in)direct driversof change relating to catch, trade and consumption.3. This research contributes knowledge about key factors relating to cephalopodsthat can support transitions towards increased food security: the value of newaquatic food species; food safety and authenticity systems; place-based innovations and empowerment of communities; and consumer behaviour, lifestyle andmotivations for better health and environmental sustainability along the foodvalue chain. We outline requirements for a sustainable, equitable cephalopod foodsystem policy landscape that values nature's contributions to people, considersUN Sustainable Development Goals and emphasises the role of seven overlapping IPBES (in)direct drivers of change: Economic, Governance, Sociocultural andSocio-psychological, Technological, Direct Exploitation, Natural Processes andPollution. We present a novel market-based adaptation of the IPBES conceptual framework—our ‘cephalopod food system framework’, to represent how thecephalopod food system functions and how it can inform processes to improvesustainability and equity of the cephalopod food system.4. This synthesised knowledge provides the basis for diagnosing opportunities (e.g.high demand for products) and constraints (e.g. lack of data about how supplychain drivers link to cephalopod NCP) to be considered regarding the role ofcephalopods in transformations towards a resilient and more diversified seafoodproduction system. This social–ecological systems approach could apply to otherwild harvest commodities with implications for diverse marine species and ecosystems and can inform those working to deliver marine and terrestrial food security while preserving biodiversity.
