“…It may be tempting to view the 'winners' as gaining access to new production. However, it is essential to recall that perceived increases come at a cost to other regions [68]. Additionally, while OA effects may appear to be locally overwhelmed by temperature driven increases this should be considered in context and interpreted as limiting potential gains, and exacerbating declines.…”

Potential socioeconomic impacts from ocean acidification and climate change effects on Atlantic Canadian fisheries

et al. 2020

Ocean acidification is an emerging consequence of anthropogenic carbon dioxide emissions. The full extent of the biological impacts are currently not entirely defined. However, it is expected that invertebrate species that rely on the mineral calcium carbonate will be directly affected. Despite the limited understanding of the full extent of potential impacts and responses there is a need to identify potential pathways for human societies to be affected by ocean acidification. Research on these social implications is a small but developing field. This research contributes to this field by using an impact assessment framework, informed by a biophysical model of future species distributions, to investigate potential impacts facing Atlantic Canadian society from potential changes in shellfish fisheries driven by ocean acidification and climate change. New Brunswick and Nova Scotia are expected to see declines in resource accessibility but are relatively socially insulated from these changes. Conversely, Prince Edward Island, along with Newfoundland and Labrador are more socially vulnerable to potential losses in fisheries, but are expected to experience relatively minor net changes in access.

“…Reduced Arctic sea ice presents new opportunities for shipping (Mumby et al, 2017) and the poleward migration of various fishery stocks, such as pelagic shelf fishes and Humboldt squid along the west coast of North America will allow some jurisdictions to increase their access to stocks or lead to the emergence of entirely new fisheries.…”

Global warming has created potential opportunities, one of which is the opening of new shorter shipping routes as a result of melting Arctic polar ice. It is expected that by the end of the 21st century, vast areas of the Arctic will be icefree. In view of these emerging developments, this extended literature review as part of a doctoral study attempts to anticipate the economic impact of emerging Arctic routes on developing countries such as South Africa, whose foreign trade rely heavily on viable coastal sea routes. The author firstly aims to demonstrate the limited studies conducted on the economic impact of the emerging route on developing countries and secondly the potential geopolitical challenges that could be faced. This review concludes with recommendations for further studies.

“…There is a mounting acknowledgement from researchers, managers and policymakers that anthropogenic stressors, such as elevated CO 2 and marine noise, are not reversible but are inevitable [55][56][57]. Management is now turning towards the prediction of a future in which degraded natural resources must sustain existing and new forms of exploitation.…”

Effect of elevated CO₂and small boat noise on the kinematics of predator–prey interactions

et al. 2018

Oceans of the future are predicted to be more acidic and noisier, particularly along the productive coastal fringe. This study examined the independent and combined effects of short-term exposure to elevated CO and boat noise on the predator-prey interactions of a pair of common coral reef fishes ( and its predator, ). Successful capture of prey by predators was the same regardless of whether the pairs had been exposed to ambient control conditions, the addition of either playback of boat noise, elevated CO (925 µatm) or both stressors simultaneously. The kinematics of the interaction were the same for all stressor combinations and differed from the controls. The effects of CO or boat noise were the same, suggesting that their effects were substitutive in this situation. Prey reduced their perception of threat under both stressors individually and when combined, and this coincided with reduced predator attack distances and attack speeds. The lack of an additive or multiplicative effect when both stressors co-occurred was notable given the different mechanisms involved in sensory disruptions and highlights the importance of determining the combined effects of key drivers to aid in predicting community dynamics under future environmental scenarios.
