In the documentary Apocalypse Cow, environmentalist and writer George Monbiot argues that much of the current farming system (except for fruit and vegetable production) will be replaced by food from microbes, freeing up large areas of land for rewilding and carbon sequestration. He also calls for fruit and vegetable farming to be reformed, e.g. by using deep-rooted cover crops to build soil fertility.
This commentary argues that there is scientific consensus on the need to build soil organic carbon because of benefits such as resistance to soil erosion, higher fertility and resilience to drought. The authors note that these benefits of building soil carbon are being obscured by high-profile disagreements on the separate question of whether or not building soil carbon may help to mitigate climate change.
This paper, co-authored by FCRN member Alexandra Sexton (who is part of Oxford’s Livestock, Environment and People project), identifies key moments in the field of cellular agriculture from the past two decades. The first wave of largely university-based research lasted until the 2013 presentation of the cultured burger created at Maastricht University, while the second wave has seen the emergence of a start-up culture.
This narrative review paper explores how understanding of nutrition and public health have changed over time, influenced by developments in science, social changes and policy-making. The paper identifies some major paradigm shifts, such as the identification of vitamins in the early 20th century, and the recognition of the link between dietary patterns and some chronic diseases in the late 20th century.
This opinion article suggests that microbial biomass from bacteria, yeasts, or fungi could be used as human food and animal feed, with the advantage of using less land compared to conventional crop production, particularly if feedstocks were derived directly from atmospheric carbon dioxide.
This free e-book, by Ahmed Khan of CellAgri, gives an overview of the field of cellular agriculture, including the basics of the concept, key terms, challenges in scaling up the technology, cellular agriculture products and regulatory aspects.
This report by the World Health Organisation calls for urgent action on the global and growing antimicrobial resistance crisis. It reports that “[a]larming levels of resistance have been reported in countries of all income levels, with the result that common diseases are becoming untreatable, and lifesaving medical procedures riskier to perform.”
This paper explores the possibility of producing food by growing insect cells in the laboratory using cell culture techniques. It suggests that it may be easier to overcome certain technical challenges to cell culture by using insect cells rather than (say) beef, pork or chicken cells.
This book by David McClements discusses scientific and technological advances (such as gene editing, nanotechnology, and artificial intelligence) in the food system, and outlines both potential benefits to people and the environment and concerns over how the technologies might be used.
A new lab-grown meat startup, Meatable, claims that it has overcome a key technical barrier - the use of serum from unborn animals to grow cells. Meatable’s meat-growing process allegedly does not need serum, because it uses pluripotent stem cells (avoided by other startups because they are hard to control). Meatable also claims their process only needs to take one cell from an animal (as opposed to a larger piece of tissue).
A traditional variety of corn grown by people from Sierra Mixe in southern Mexico can thrive in poor soils without needing much extra fertiliser. A group of researchers have shown that the plant is able to draw nitrogen from the air through mucus-laden aerial roots on its stems. It’s hoped that the trait can eventually be bred into commercial corn strains.
Startup New Age Meats has served the world’s first lab-grown pork sausages to journalists. The fat and muscle cells were allegedly grown from pork cells extracted from a live pig - in contrast to the world’s first lab-grown burger, showcased in 2013, where the initial cell samples came from slaughtered cattle.
This book, edited by Ramesh Namedo Pudake, Nidhi Chauhan, and Chittaranjan Kole, highlights ways in which nanomaterials can be used in agriculture. The book covers both social and environmental aspects.
Several companies are using microbes to improve crop performance. One of them is Indigo, which uses machine learning to identify the microbes associated with healthy plants and then coats seedlings with these microbes. Indigo’s method has increased wheat yields by 15% and cotton yields by 14% in trials.
The Intergovernmental Panel on Climate Change (IPCC) has brought out a handbook to help its scientists communicate climate change issues effectively.
This article in the European Molecular Biology Organisation (EMBO) journal examines NGOs’ opposition to agricultural biotechnologies. It finds that opposition to genome editing cannot be dismissed as being solely emotional or dogmatic, as is often asserted by the scientific molecular biology community (see for example this 2016 letter by 107 Nobel Laureates calling NGO action against GM a "crime against humanity”). Instead, opposition to genome editing among research participants was rooted in three areas of scepticism around the framing of food security problems and the proposed solutions.
