The UK’s Countryfile TV programme has featured research by the Centre for Agroecology, Water and Resilience (CAWR) at Coventry University, which is using farm-based trials to study whether feeding biochar (a form of charcoal) to cattle can reduce their emissions of methane and ammonia.

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.

This paper provides an assessment of the environmental impacts of converting waste streams from the food industry into products such as fertiliser, pet food, livestock feed or feed additives using the larvae of Hermetia illucens, the black soldier fly.

FCRN member Samuel Smith of international non-profit Forum for the Future has created a three-part blog series exploring sustainability issues linked to animal feed. The blog posts round up the findings of Forum for the Future’s project Feed Compass: acting on animal feed.

This article on the environmental impacts of different types of animal feed (including fishmeal, soy, fava beans, algae and various forage crops) features commentary from FCRN member Sam Smith, who has contributed to the Feed Compass work by Forum for the Future.

71% of European Union farmland is used to feed livestock and 18% to 20% of the EU’s total budget goes to livestock farms, according to this report by NGO Greenpeace.

FCRN member Christopher Schlottmann and Jeff Sebo, both of New York University, have written a book discussing empirical, ethical, and social dimensions of food, animals, and the environment, providing both big picture and more detailed analysis, including updated statistics.

Farmed fish are often fed on forage fish (such as anchovies and sardines) caught from the wild. A new paper points out that demand for forage fish to support aquaculture production is forecast to grow beyond the maximum sustainable supply level. The authors calculate that demand for forage fish could be reduced to below the maximum supply limit by combining a number of measures: reducing use of forage fish in land-based agriculture, replacing some forage fish with fish trimmings from processing, and reducing the proportion of forage fish in the diets of non-carnivorous farmed fish.

Environmental campaigning organisation Feedback have released a new report in which, having examined environmental, economic and safety factors, it lays out the case for lifting the ban on feeding surplus food to pigs in the UK. The report finds that up to 2.5 million tonnes of food waste from the UK manufacturing, retail and catering sectors could be fed safely to pigs, if legalised. The report draws on the work of an expert panel convened by EU REFRESH, who concluded that food waste can be safely fed to pigs if it is heat-treated and processed properly, and conducted in a limited number of well-regulated off-farm processing facilities. The report was featured on BBC1’s Countryfile and in the Times.
