July 14, 2020 — Aquaculture, the relatively young but fast-growing industry of farming of fish and other marine life, now produces around half of all seafood consumed by humans.
A new paper from American University published today examines the economics of an aquaculture industry of the future that is simultaneously environmentally sustainable and nutritious for the nearly 1 billion people worldwide who depend on it for health and livelihoods.
Of the scenarios the paper discusses, included are two approaches that illustrate what aquaculture might look like if nations refocus inward for food and nutrition security in the COVID-19 era.
“Seafood is essential to meeting global food and nutrition security goals,” said Jessica Gephart, the paper’s primary author and an assistant professor of environmental science at American University. “Under what circumstances, and with what policies, can we maximize aquaculture for its nutrition benefits and sustainability for all who rely on seafood?”
This is a challenging question to answer, especially in the COVID-19 era. As the pandemic is still unfolding, the full scope of long-term damage to food systems is unknown, the paper notes. Yet, the aquaculture industry is suffering major setbacks, as some exports are being halted, workers are being laid off, demand has dramatically decreased, production units are incurring large losses and some countries are reconsidering their reliance on foreign seafood. The authors note that such setbacks “can be particularly long-lasting for a budding sector, with many young farms that potentially lack the capital to weather the storm and the political clout to secure sufficient recovery aid.”
The demand for seafood is expected to increase significantly by 2050, the paper notes, if historical trends in income and population growth, urbanization, and diets are maintained. This has prompted researchers to contemplate the future role of aquaculture in meeting demand and supporting nutrition needs. “Nutrition sensitivity” refers to the multiple benefits derived from diverse foods, including improving nutrition, valuing the social significance of food, and supporting livelihoods.
