Flexibility through bundles of capital: The capabilities of Indonesian small-scale handline tuna fishers under voluntary sustainability certification

As key tuna producers and exporters globally, developing countries are exposed to voluntary sustainability certification to respond to market and consumer demands. Only recently, small-scale fisheries have received attention in this respect. Despite small volumes traded, fishing activities are essential for maintaining the livelihoods of small-scale fishers. Their environmental footprint is lower than large-scale fisheries, yet lack of capital, capabilities, and conflicting interests along the value chain have hindered their participation in certification schemes. This study employs Sen 's capability approach to understand the extent to which a voluntary standard develops the capabilities of small-scale tuna fishers. We use a case study of the Fair Trade USA Capture Fisheries Standard (CFS) in the province of Maluku, Indonesia, established in collaboration with an Indonesian nongovernmental organization, Yayasan Masyarakat dan Perikanan Indonesia . We show that fishers use a bundle of different kinds of capitals to develop their capabilities for compliance with the certification standard. This bundle of capitals consists of a combination of prescribed capitals (the capitals necessary to comply with the certification standard) and alternative capitals that fishers use to develop their abilities for their compliance. Instead of using human capital as emphasized by the certification standard, in this study, we found that fishers use social capital as their main capital to comply with the standard, which makes it the primary source for improving their capabilities. In conclusion, we found support for the need to strengthen flexibility in the implementation of sustainability standards to increase their effectiveness as a sustainability governance mechanism.
