This blog by researchers Cedric Simon and Ha Truong from CSIRO Agriculture & Food discusses a method they have developed to reduce the amount of wild fish needed for prawn feed.
In this article, researchers from the UK and USA present their findings of a 2015 case study of Scottish salmon farming, their goal being to illuminate the economic and food security value that may be gained through improved management and use of aquaculture by-products.
This book, edited by Jessica Duncan and Megan Bailey, includes chapters on a wide range of topics such as cultured meat, aquaculture, land rights and Arctic food security initiatives.
After a 25 year wait for approval, approximately five tons of genetically modified (GM) salmon have been sold in Canada in the last few months. The fish, which contains genes from Chinook salmon and ocean pout, can grow twice as fast as an Atlantic salmon and requires 75% less feed to grow to the same size. These changes can ultimately reduce the carbon footprint of each genetically modified salmon by up to 25 times, the company claims.
This research calculates the carbon footprint of a meal to give a tangible example, aimed at the public in the US, about how daily food decisions can affect deforestation and greenhouse gas emissions (GHGe). The study uses a life-cycle assessment (LCA) approach that takes into account GHGe arising from the conversion of mangrove to cattle pastures and mangrove to shrimping ponds as well as from forests to pasture (cattle induced deforestation).
This paper, taken from an inaugural edition on planetary health in the Lancet, analyses global food and nutrient production and diversity by farm size, providing evidence on how smallholder farmers contribute to the quantity and quality of our global food supply and discussing the structural impacts of agriculture on nutrient availability.
This is the 2016 edition of the FAO’s State of World Fisheries and Aquaculture. The report estimates that fish now provide 6.7% of all protein consumed by humans globally, passing the 20kg per capita and year mark for the first time.
In this paper, researchers at the National University of Singapore identify the major land use changes associated with mangrove deforestation in Southeast Asia, with an aim of ultimately facilitating appropriately targeted policy interventions to manage the forests. Over a 12-year period, the researchers quantified LULCC in deforested patches, and classified the replacement land uses (e.g. aquaculture).
This report, Food Futures, by the UK’s waste agency WRAP, looks at a broad range of food sustainability challenges for the future and at possible solutions.
This paper finds that increasing global demand for fish (due to increasing incomes and worldwide population growth) and developments in fishing methods together threaten to further increase pressure on the most popular fish types. It considers improvements in two areas that may decrease this pressure; increasing the production of farmed fish (aquaculture) and improving the effectiveness of fisheries management.
The authors assess how various scenarios of change would affect future wild stock status and simulate the stock development until the year 2048. Through different scenarios they outline ways that the fishery and aquaculture sectors might develop in the coming decades for four popular types of edible fish that are the most important for the world market; sea bass, salmon, cod and tuna.
Over 50 expert presentations have been given on different aspects of climate change and agriculture in the MICCA Programme webinars during the past 3 years. Examples include recent webinars on conservation agriculture and climate-smart & gender-sensitive aquaculture.
This article reports that a new fish and animal feedstock product which uses methane gas may be released into the European feedstock markets from the beginning of 2018. The product, FeedKind, is currently in pre-production phase and it is described that the manufacturing process is very similar to the way in which Marmite and other yeast-extract sandwich spreads are produced.
In 2014, the FCRN released a major report entitled Appetite for change: social, economic and environmental transformations in China’s food system. This provided a detailed and integrative analysis of the dramatic changes in China’s food system over the last 35 years, explored emerging environmental, health, economic and cultural trends and challenges, and identified policy and research implications.
