This article by FoodPrint discusses the tension between the purported environmental benefits of kelp farming and consumers’ lack of familiarity with kelp as a food, and describes “regenerative” kelp farming systems that also produce oysters, clams and mussels. It sets out several ways in which kelp can be used, including in foods such as pesto or lasagne, as well as other uses such as bioplastics, fertiliser, biofuel and animal feed.
This report from US charity The Nature Conservancy explores how private investors can help to meet the demand for sustainable seafood by investing in new forms of aquaculture that have lower negative environmental impacts than conventional aquaculture.
The World Bank has released a short working paper arguing that the expansion of seaweed farming in tropical developing countries could have large positive impacts on local poverty, ecosystem management and climate change mitigation. The report goes through different benefits and uses of seaweed production and briefly discusses current and potential markets for the crop.
Drawing on the expertise of 21 institutions worldwide, the UN University's Canadian-based Institute for Water, Environment and Health, and the Scottish Association for Marine Science, a UNU associate institute, have published guidelines for the burgeoning seaweed industry.
A chance discovery was made in Canada 11 years ago, when it was observed that cattle in a paddock near the sea are more productive. This led to research showing that feeding cows seaweed not only helped improve their health and growth, but also reduced their enteric methane emissions by about 20%.
This Dutch study looks at consumers’ potential preferences for snacks made from a range proteins with lower environmental impact and segments according to their values and attitudes to food. In this hypothetical experiment, people could choose between written descriptions of a range of snacks containing lentils or beans, seaweed, insects or a combination of meat and a non-specified meat substance. The study found that a hybrid meat product may be preferred by many consumers before insects or seaweed. The researchers found that, overall, people who tended to eat more meat were less likely to choose the lentils and seaweed snacks while those who ate more fish were more likely to choose the seaweed snack.
John Forster, an FCRN mailing list member, has written two very interesting articles on aquaculture for the UK Research Councils’ Food Security website www.foodsecurity.ac.uk
