Crona, B.I., X. Basurto, D. Squires, S. Gelcich, T.M. Daw, A. Khan, E. Havice, V. Chomo, M. Troell, E.A. Buchary, E.H. Allison. Towards a typology of interactions between small-scale fisheries and global seafood trade. Marine Policy doi:10.1016/j.marpol.2015.11.016

Fish and fish-related products are among the most highly traded commodities globally and the proportion of globally harvested fish that is internationally traded has steadily risen over time. Views on the benefits of international seafood trade diverge, partly as a result from adopting either an aggregate national focus or a focus on local market actors. However, both views generally assume that the trade in question is cha...

Sandström, A., Ö. Bodin, B. Crona. 2015. Network governance from the top: The case of ecosystem-based coastal and marine management. Marine Policy 55: 57–63.

Contemporary environmental policy incorporates a collaborative approach, and conservation management commonly denotes the formation of governance networks on the sub-national level. This trend toward networks implies a shift in the mode of public governance since state-centered top-down control is replaced by a primary focus on governing networks from the top. Previous research has studied the performance of collaborative ne...

Wamukota, A.W., B. Crona, K. Osuka, T.M. Daw. 2015. The importance of selected individual characteristics in determining market prices for fishers and traders in Kenyan small-scale fisheries. Society & Natural Resources 28: 959–974

This article examines how selected socioeconomic characteristics of fishers and traders shape market prices at five coastal communities in Kenya. Focus groups elicited perceived factors affecting market prices, which were then tested using quantitative analysis. Ownership of fishing gear by fishers negatively influenced the prices taken. Fish traders who bought larger quantities paid a higher price. There was no significant...

Keystone species have a disproportionate influence on the structure and function of ecosystems. Here we analyze whether a keystone-like pattern can be observed in the relationship between transnational corporations and marine ecosystems globally. We show how thirteen corporations control 11-16% of the global marine catch (9-13 million tons) and 19-40% of the largest and most valuable stocks, including species that play importa...

Marín, A., Bodin, Ö., Gelcich, S., & Crona, B. (2015). Social capital in post-disaster recovery trajectories: Insights from a longitudinal study of tsunami-impacted small-scale fisher organizations in Chile. Global Environmental Change, 35, 450-462

Increased likelihood and severity of coastal disasters in the 21st century represent major threats for coastal communities’ resource management capacity and livelihoods. Disaster research has frequently looked for singular factors explaining why some communities are more resilient and better equipped to cope with and recover from disasters. This study draws on Chile’s 2010 tsunami to evaluate the effects of both internal (soc...

Global seafood sourcing networks are expanding to meet demand. To describe contemporary fishery expansion patterns, we analyzed the worldwide exploitation of sea cucumber (Echinodermata: Holothuroidea) traded via Hong Kong for consumers in China. In just 15 years (1996–2011), the sea cucumber sourcing network expanded from 35 to 83 countries; sea cucumber fisheries serving the Chinese market now operate within countries cumu...

Borgström, S., Ö. Bodin, A. Sandström, B. Crona. 2015. Developing an analytical framework for assessing progress toward ecosystem-based management. Ambio 44: 357–369.

Ecosystem-based management (EBM) has become a key instrument of contemporary environmental policy and practice. Given the increasingly important role of EBM, there is an urgent need for improved analytical approaches to assess if and to what extent EBM has been accomplished in any given case. Drawing on the vast literature on EBM, we identify five key ecosystem aspects for assessment. By linking these aspects to four phases ...

Globalization has increased the speed and flow of people, information, and commodities across space, integrating markets and increasing interdependence of geographically dispersed places worldwide. Places historically driven by largely local forces and market demands are now increasingly affected by drivers at multiple scales. Trade is particularly important in driving these changes and more fish is now exported to internation...

Wamukota, A., T.D. Brewer, B. Crona. 2014. Market integration and its relation to income distribution and inequality among fishers and traders: The case of two small-scale Kenyan reef fisheries. Marine Policy 48: 93-101.

This study, carried out in five fishing communities along the Kenyan coast, examined fisheries-derived income of fishers and traders in two different invertebrate fisheries (octopus and sea cucumber) and tested if differences in global market integration of these two products could explain differences in income inequalities among actors involved in the two fisheries. The structure of the value chains was mapped, differences ...
