This research shows that global replacement of fish meal and fish oil in aquaculture feed with alternative feeds (including algae, bacteria, yeast and insects) could reduce aquaculture’s demand for forage fish while - depending on the specific mix of alternative feeds - maintaining feed efficiency and levels of omega 3 fatty acids in the farmed fish.
This report from UK food waste NGO Feedback and the Changing Markets Foundation assesses ten UK supermarkets on their aquaculture supply chain policies and practices, particularly regarding the use of wild fish as feed for farmed fish. Seven out of ten supermarkets scored less than 30%, with ALDI performing worst at 12% and Tesco performing best at 60%. The report finds that aquaculture operations for UK supermarkets consumed 2.5 times as much wild fish as the amount of farmed fish produced.
This report from the UK’s Eating Better alliance argues that replacing red meat with chicken is not a sustainable solution, and that growing consumption of poultry meat comes with costs to health, the environment, animal welfare and rural livelihoods. The report calls for reduced chicken consumption in the UK (to be replaced with plant proteins such as beans and nuts), and shifting away from intensive chicken farming towards “mixed and regenerative farming systems”.
This book addresses food waste from a variety of perspectives, including agriculture, food science, industrial ecology, history, economics, consumer behaviour, geography, theology, planning, sociology, and environmental policy.
This report from environmental campaign group Greenpeace UK examines how chicken consumption in the UK is linked to deforestation, through production of soy for animal feed. It sets out the “soya footprint” of supermarkets, fast food outlets and manufacturers, although figures are not available in all cases.
Will Nicholson of the FCRN has contributed to this report on the future of protein by Forum for the Future. The report asks whether the food industry is taking sufficient action on providing sustainable, healthy protein.
This brief from Trase (a partnership between the Stockholm Environment Institute and Global Canopy) examines soy grown on unregistered farms in Brazil. Legally, farms in Brazil should be registered with the Rural Environmental Registry as the first step of complying with the Forest Code, which stipulates how much native vegetation should be left intact on private properties.
This case study from UK sustainability consultancy 3Keel describes 3Keel’s work with seven European retailers to quantify the amount of soymeal used for animal feed in these supply chains, identify where the soy was produced and determine whether any of that soy was certified as being deforestation-free.
This report from the UK charity Waste and Resources Action Programme (WRAP) provides the latest estimates for food losses and food waste in primary production (i.e. on farms) in the UK. It finds that 3% of food harvested is wasted at the farm stage (sent to waste treatment such as composting without first being used for another purpose, or left in the field) and 4% is surplus (material intended for food uses that ends up being redistributed to people, fed to animals or used for other purposes), making a total of 7%.
This report by UK food waste campaigning organisation Feedback examines the use of wild fish and land by the Scottish farmed salmon industry. It finds that the industry, which is largely controlled by six companies, already uses the same amount of wild fish that the whole UK population purchases, and that it would need to use two-thirds as much again to meet its growth ambitions.
Wageningen University and Research has formed a consortium together with several private companies to research the use of co-products and residues from the food sector and industry as animal feed. A particular research focus will be on increasing Europe’s self-sufficiency in feed materials.
This paper, produced by the Centre for the Study of Existential Risk at the University of Cambridge, outlines a system that could produce animal feed with lower environmental impacts than conventional soybean production. The system combines LED lighting, indoor photobioreactors, atmospheric carbon capture and geothermal energy to produce an algae-based feed product.
This report from the US-based campaigning organisation Changing Markets Foundation examines the impacts of catching wild fish to feed to farmed fish in aquaculture operations, i.e. reduction fisheries.
This paper quantifies the resource use implications of replacing fishmeal with plant-based ingredients in the feed used to farm shrimp. It finds that increasing the proportion of plant-based ingredients in shrimp feed could reduce pressure on marine resources, at the cost of increased use of freshwater, land and fertiliser.
