The Nereus Program facilitated a side event on February 16 entitled: “Co-Benefits of Achieving SDG Goal 14 to Wider SDGs: Prioritizing Action Given Climate Change and Social Inequity”. The theme of the event was implications of changing oceans on the advancement of SDG’s, with an emphasis on the co-benefits of achieving ocean targets on other environmental, economic, and social equity goals.
Variations in climate lead to fluctuations and changes in fish stocks; they can have effects on such things as fish behaviour, distributions and growth. Because of this, fisheries management has to respond dynamically to these fluctuations. If management decisions are made primarily on past patterns, the negative impacts can be exacerbated, especially with climate change.
West Africa may be one of the most vulnerable regions to climate change. The region is highly dependent on fisheries for livelihoods and as an important food source. The marine resources of West Africa are currently threatened by overfishing and climate change-induced ocean warming could see fish stocks migrate away from the area and into cooler waters. If CO2 emissions continue at their current levels, the region could see a 50% decline in fisheries-related jobs and a total annual loss of US$311 million, found a study by Nereus Program researchers.
Phytoplankton are the foundation of ocean life, providing the energy that supports nearly all marine species. Levels of phytoplankton in an ocean area may seem like a good predictor for the amount of fish that can be caught there, but a new study by Nereus Program researchers finds that this relationship is not so straightforward
According to the FAO, anchovy and sardine made up 13% of global catch in 2012. These small fish are consumed by humans, marine mammals, seabirds, squid, and other fish. They are also used for aquaculture feed, industrial oil, and health supplements. “Climate, Anchovy, and Sardine” a new study in the Annual Review of Marine Science, co-authored by Nereus Alumni Rebecca Asch (Princeton University) and Ryan Rykaczewski (University of South Carolina), reviews the past, present, and future of anchovy and sardine.
A new Nereus Program study published in Science on meeting the Paris Agreement global warming target received media coverage in The Independent, The San Diego Union-Tribune, Gizmodo, CBC News, The Canadian Press, El Mundo, Sciences et Avenir, Hamburger Abendblatt, and more.
Meeting the Paris Agreement global warming target of 1.5°C will have large benefits to fisheries, finds a new Nippon Foundation-Nereus Program study published in Science. For every degree Celsius decrease in global warming, potential fish catches could increase by more than three million tonnes per year.
Coastal Indigenous people eat, on average, 15 times more seafood per person than non-Indigenous people in the same country, finds a Nippon Foundation-Nereus Program study published today in PLOS ONE. This highlights the need to consider food sovereignty and cultural identity as part of fisheries policy and Indigenous human rights.
Nereus Fellow at Princeton University Colleen Petrik won the Science Board Best Presentation Award at the North Pacific Marine Science Organization (PICES) annual meeting, held in San Diego, from November 2 to 11. She gave a plenary presentation on “The response of fisheries production to natural and anthropogenic forcing: past, present and future”, using the results of the model she developed with her Nereus research.
“Our energy choices have ramifications for many other types of pollutants,” said Elsie Sunderland, Associate Professor of Environmental Science and Engineering at Harvard University and Nereus Program collaborator. “Hydroelectric: when we flood our reservoirs we actually cause a dramatic pulse in methylmercury production, which is neurotoxic, and we also cause a pulse in CO2 and methane.”
