The ocean plays a critical role in supporting human well-being, from providing food, livelihoods and recreational opportunities to regulating the global climate. Sustainable management aimed at maintaining the flow of a broad range of benefits from the ocean requires a comprehensive and quantitative method to measure and monitor the health of coupled human–ocean systems. We created an index comprising ten diverse public goals for a healthy coupled human–ocean system and calculated the index for every coastal country. Globally, the overall index score was 60 out of 100 (range 36–86), with developed countries generally performing better than developing countries, but with notable exceptions. Only 5% of countries scored higher than 70, whereas 32% scored lower than 50. The index provides a powerful tool to raise public awareness, direct resource management, improve policy and prioritize scientific research.

The dominant discourse of fisheries science and management, bioeconomics, places the behavior of individual fishermen operating on an open-access commons at the center of its understanding of fisheries resources and the fishing industry. Within this discourse, fishermen are the sole actors and the fishery is the fixed stage for an inevitable "tragedy of the commons." Starting from these particular assumptions of both subject and space, bioeconomics proposes solutions to fisheries crisis that differ sharply from fishers' perceptions of the resource and their desires for management. These divergent understandings of both the natural and social environments are reflected in the maps produced by fisheries scientists/managers and those produced by fishers themselves. Remapping fisheries in terms of fishers' perceptions and scales of operation reveals diverse natural landscapes and communities in which the dominant discourse charted only quantities of fish and individual fishermen. The landscape of fishing communities, once made visible, suggests an opportunity for forms of area-based management that might facilitate community development rather than just individual prosperity.
In this period of environmental change, understanding how resource users respond to such changes is critical for effective resource management and adaptation planning. Extensive work has focused on natural resource responses to environmental changes, but less has examined the response of resource users to such changes. We used an interdisciplinary approach to analyse changes in resource use among commercial trawl fishing communities in the northwest Atlantic, a region that has shown poleward shifts in harvested fish species. We found substantial community-level changes in fishing patterns since 1996: southern trawl fleets of larger vessels with low catch diversity fished up to 400 km further north, while trawl fleets of smaller vessels with low catch diversity shrank or disappeared from the data set over time. In contrast, trawl fleets (of both large and small vessels) with higher catch diversity neither changed fishing location dramatically or nor disappeared as often from the data set. This analysis suggests that catch diversity and high mobility may buffer fishing communities from effects of environmental change. Particularly in times of rapid and uncertain change, constructing diverse portfolios and allowing for fleet mobility may represent effective adaptation strategies.
While acknowledging this trajectory, however, we also respond affirmatively to Ferguson's (2009, 169) question about whether we can engage with "new configurations of governmental power in a way that goes beyond the politics of denunciation, the politics of the 'anti.'" Rooted in our ethical concern for the well-
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
