While the global rush to control land resources is well established, ‘power-grabs’ in relation to marine and coastal resources are less well researched. Under the banner of ‘blue growth’, such power-grabs are taking shape through global policy processes that purportedly align the needs of the poor with profit interests and climate change concerns. This contribution critically interrogates these policy proposals and situates them within broader neoliberalization of nature debates. It is argued that the policy proposals fail on their own terms and are a form of ‘antipolitics’ that precludes more radical visions of addressing environmental and climate change issues. In an attempt to challenge this, small-scale fishers’ movements are increasingly framing their opposition in terms of the broader struggle for ‘food sovereignty’.
