Capture fisheries are constituted through historically specific environmental conditions and social and economic relations of production. Fisheries, whether saltwater or freshwater, are an important source of animal protein, livelihoods and exchange value in international trade, and are presently undergoing rapid socio‐ecological change. To explore the political economy and ecology of capture fisheries around the world, this paper synthesizes the insights of 11 empirical studies and places fisheries in the broader context of the capitalist relations of production through which they operate. The competitive market dynamics of fisheries production and consumption are examined, as well as the forms of social‐property relations, social differentiation, labour exploitation and resistance that occur within them. This paper highlights some of the ways in which the unique combination of characteristics associated with fish and fisheries complement and complicate familiar questions in agrarian political economy. It concludes by identifying future research directions.

Globally, and nationally in Australia, bushfires are expected to increase in frequency and intensity due to climate change. To date, protection of human health from fire smoke has largely relied on individual-level actions. Recent bushfires experienced during the Australian summer of 2019–2020 occurred over a prolonged period and encompassed far larger geographical areas than previously experienced, resulting in extreme levels of smoke for extended periods of time. This particular bushfire season resulted in highly challenging conditions, where many people were unable to protect themselves from smoke exposures. The Centre for Air pollution, energy and health Research (CAR), an Australian research centre, hosted a two-day symposium, Landscape Fire Smoke: Protecting health in an era of escalating fire risk, on 8 and 9 October 2020. One component of the symposium was a dedicated panel discussion where invited experts were asked to examine alternative policy settings for protecting health from fire smoke hazards with specific reference to interventions to minimise exposure, protection of outdoor workers, and current systems for communicating health risk. This paper documents the proceedings of the expert panel and participant discussion held during the workshop.

Fishing share systems that distribute ‘fishing surplus’ among crew are widespread in global fisheries. One recent analysis identifies the New England ‘lay’ share system as a form of ‘non‐capitalism’ because of the way that surpluses are shared (St Martin 2007). Through ethnographic, historical and economic analysis of Scottish commercial nephrops trawler fisheries, this paper demonstrates that fishing share systems are adaptable to the exploitation of labour. While share systems seem to have their origins in shared ownership of fishing boats and gear, it is the present lack of this link in Scotland that has created the conditions for labour itself to become a commodity and share systems to function as a variable and casual wage. This paper argues that the dependence of the fishery on commodity production and its reliance on labour as a commodity makes it fully capitalist, even in the presence of a share system, and explores the social and ecological consequences of the development of these more conventionally capitalist class relations.

What are Marxists to make of the new wave of materialism that has become influential in anthropology and across the social sciences and humanities? An ethnography of fishing in coastal Scotland and an analysis of Tim Ingold’s ecological anthropology demonstrates both the usefulness and gaps in contemporary ecological and materialist anthropology. It finds that the reduced role for political economy, human intentionality, and material results in this literature significantly reduces their explanatory power. Efforts to unite analysis of humans and nonhumans have led to a lack of attention to the divisions within human societies, particularly the alienation of labor and therefore of ecological relations in capitalism. Understanding these dynamics is essential to contending with the current planetary ecological crisis.
