A small amount of single-cell protein has been produced using electricity and carbon dioxide alone. The researchers working on this believe the protein produced in this way could be further developed for use as food and animal feed. The protein can be produced anywhere that renewable energy, such as solar energy, is available.
This paper proposes a solution to the problems associated with the high inefficiencies and indirect detrimental environmental impacts caused by reactive nitrogen use in agriculture.The researchers suggest that land-based agriculture could be bypassed and that Haber Bosch derived nitrogen could be used directly for reactor based microbial protein production. The advantages of microbial protein production are summarised, as are the opportunities and technical challenges for large-scale production. The authors emphasise that, aside from the scientific innovation required, the main challenge to address is obtaining acceptability from regulators and consumers.
This paper shows that a huge amount of nutrients is wasted each day in the US food supply, and that much of this waste includes important nutrients that are currently under-consumed in the US. It is one of the first studies to calculate the nutritional value of food wasted in the US at the retail and consumer levels, shining a light on just how much protein, fibre and other important nutrients end up in the landfill in a single year.
This paper compares stylised, hypothetical dietary scenarios to assess the potential for reducing agricultural land requirements. It suggests that a combination of smaller shifts in consumer diet behaviour – such as reducing beef consumption by replacing with chicken, introducing insects into mainstream diets and reducing consumer waste – could reduce agricultural land requirements.
A Global Meat News survey of top industry professionals analysing trading trends and impacts on the meat industry globally shows that most respondents (24%) stated that the pressure to limit meat consumption was the factor that hit the industry as a whole the hardest in 2016.
The report Redefining Protein: Adjusting Diets to Protect Public Health and Conserve Resources distils current research looking at the social and environmental impacts of producing high-protein foods other than meat (legumes: pulses and soy, nuts and seeds, eggs and dairy). It aims to provide hospitals with key information to design healthier meals.
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.
In this paper, the authors present an analysis of the nitrogen cycle in the agricultural production system of 12 world regions. From these results, they go on to suggest improvements in nitrogen use by changing the role of human diet, international trade and local production.
Over the past half-century, the paradigm for agricultural development has been to maximize yields through intensifying production, especially for cereal crops. But achieving food security and building a healthy, resilient global food supply is about more than just the quantity of calories provided. New metrics of success and methods of evaluation are needed in order to measure progress towards meeting the world’s nutritional needs within environmental limits.
A group of investors, worth $1.25 trillion, has contributed to a report calling for food companies to change the way in which they include protein in their products to reduce environmental risk. The FAIRR initiative’s report – The Future of Food: The Investment Case for a Protein Shake Up – argues that forward-looking investors and businesses should act now to help shape a new market in sustainable protein, with less of this macronutrient coming from animals, and more from plants (and perhaps from insects and algae).
