New research projects fisheries and freshwater aquaculture will experience the highest cumulative climate hazards for the rest of this century with SIDS and countries in Africa, South Asia and Southeast Asia at a relatively higher risk from climate change.
PENANG, November, 18, 2021 – New research indicates critical aquatic food systems such as fisheries and freshwater aquaculture will experience the highest cumulative climate hazards in the twenty-first century if carbon emissions are not substantially and rapidly reduced.
Aquatic foods -- diverse animals, plants, and microorganisms grown and harvested from water -- are central to the livelihoods, food and nutrition security of more than 800 million people in developing countries.
Rich in bioavailable micronutrients and essential fatty acids, aquatic foods are considered superfoods that are healthy, not just for people but also the planet. Small fish, shellfish and seaweeds in particular have enormous nutritional value with a lower environmental footprint than land-based animals. Sustainable management of aquatic animals and plants means stored carbon dioxide that would have otherwise been released to the atmosphere.
By 2100, aquatic food production in all countries is expected to face high levels of climate threat, with a disproportionate impact felt by the world’s poorest countries. At the same time, the global population is expected to surpass 11 billion, many of whom will rely on aquatic foods for their incomes and nutrition.
Small island developing states (SIDS) and countries in Africa, South Asia and Southeast Asia are particularly at high risk and urgent climate action and investment in aquatic food systems is necessary to ensure the food, nutrition security and livelihoods of people living in these regions are not gravely compromised.
In Compound climate risks threaten aquatic food system benefits, one of five initial scientific papers published as part of the Blue Food Assessment, 22 authors cautioned that the lack of data and modelling tools especially for countries and systems most at risk of climate hazards if left unaddressed, will result in resilience investments going elsewhere where data is available, perpetuating current inequities.
Using an integrative food system approach that the authors developed, they compared the risk that climate change poses to the potential for aquatic foods to contribute to sustainable development. From the analysis, four distinct risk profiles namely low, medium, high and very high were identified and corresponding policies and management actions to enhance the climate resilience of aquatic food systems were proposed.
The authors projected that climate mitigation efforts to keep global warming well below two degrees Celsius will be able to limit the climate hazards faced by most aquatic food systems to either medium or low. Although climate mitigation activities will result in substantially reduced climate hazards, some negative impacts will still be felt by aquatic food systems as some climate risks will take a longer time to be reversed.
Elaborating on the significance of the findings, WorldFish Global Lead for Climate Resilience and Environmental Sustainability Dr. Essam Yassin Mohammed said:
“This latest scientific evidence must be instrumental in shaping investments and policy intervention to mitigate the impacts of climate change and ensure aquatic food systems can continue to make significant contributions to food and nutritional security and overall sustainable development objectives.”
Considering the high levels of climate risk for multiple outcomes across much of the developing world, action to support the long-term sustainability, resilience and equity of aquatic food systems is urgently needed. With countries and regions exhibiting different risk profiles, region-specific and context-specific risk reduction interventions that are guided by principles of equity and fairness is needed.
While the research paper focused on countries with high climate risk, countries with low to medium risk will also be facing increased climate hazards domestically as well as transboundary climate risk due to species movement and trade of aquatic foods and feeds. There is a need for justice-informed collaboration towards climate-proofing of aquatic food systems that transcends national and regional boundaries.
WorldFish Director of Aquaculture and Fisheries Sciencefor CGIAR Research Program on Fish Agri-Food Systems (FISH) Dr. Mike Philips noted:
“The impacts of climate change are more pronounced in developing countries in Africa, Asia, Latin America and the Pacific. Failure to make sufficient investments to build the resilience of aquatic food systems in these regions means risking failure to achieve key sustainable development objectives.”
Developing countries, including SIDS, generally experience higher consumption of aquatic foods from marine and freshwater sources, higher dependence on production trade and supply chain revenue and higher numbers of aquatic food-dependent livelihoods. Coupled with the reality that climate hazards are concentrated in the tropics and subtropics, these countries are faced with a double jeopardy in exposure to climate hazards impacting nutrition and health, and economic and social outcomes.
WorldFish Executive Director for Science and Research Prof. Edward Allison elaborated:
“Aquatic foods are the closest we have to a ‘nature-based solution’ to the challenge of transforming our current food system to one that is healthier, more sustainable and more fairly distributed. Aquatic foods are also often harvested from waters that are ‘commons’ – not restricted to private ownership – so even the landless poor have access to nutrient-rich aquatic foods.”
The Blue Food Assessment is an international joint initiative bringing together over 100 scientists from more than 25 institutions. Led by the Stockholm Resilience Centre at Stockholm University, Stanford University, and EAT, the Blue Food Assessment supports decision-makers in evaluating trade-offs and implementing solutions to build healthy, equitable and sustainable food systems.
WorldFish has been a key research contributor to the Blue Food Assessment, with seven of its scientists among the authors of the papers released. WorldFish has guided the direction of the study through representation on the Blue Food Assessment Scientific Leadership Team by Eddie Allison, director of science and research, Shakuntala Thilsted, global lead for nutrition and public health, and Mike Phillips, director of aquaculture and fisheries science for CGIAR Research Program on Fish Agri-Food Systems (FISH).
A strategic brief elaborating ways to accelerate climate resilience of aquatic food systems was recently published by the CGIAR Research Program on Fish Agri-Food Systems (FISH), led by WorldFish in partnership with the International Water Management Institute, Wageningen University & Research, James Cook University and the University of Greenwich.
In the recently concluded United Nations Climate Change Conference (COP26), WorldFish highlighted the urgent need for action and investments to realize the triple wins aquatic foods offer for nature, climate and people through a shared blue prosperity.
Read the research paper to learn more about why urgent measures are required to mitigate climate hazards that may affect the nutritional, health, livelihoods, economic and cultural benefits aquatic foods bring to billions of people around the world.
