This article in the Guardian explores the links between food production and COVID-19. It points out that, while the virus is likely to have been transmitted to humans via a pangolin at a “wet” market in Wuhan, China, the virus may have come to pangolins from wild bats. Some smallholder farmers, the article suggests, began to rear “wild” animals (such as pangolins) for income when their previous livestock farming was undercut economically by industrial farming methods, and may also have been pushed onto marginal land (nearer to forests, bats and the viruses hosted by bats) by industrial agriculture’s expansion.
This paper sets out how far different sources of methane (both agricultural and non-agricultural) can be reduced by 2050, via technical changes. It argues that since methane accounts for about 40% of the warming effect of all greenhouse gases in the short term (because of its high Global Warming Potential but short atmospheric lifetime), reducing methane emissions is therefore useful for mitigating climate change between now and 2050.
This blog post by Joe Herbert, PhD student in Human Geography at Newcastle University and editor for Degrowth.info, argues that the degrowth movement (which advocates for shrinking economic activity) has not sufficiently considered the role of animals in its vision of a “just and redistributive downscaling of material and energetic throughput in wealthy countries as a means to achieve ecological sustainability”.
The University of Oxford’s Livestock, Environment and People project has published a new series of blog posts exploring controversies in the food system. The series aims to explore and clarify areas where evidence is unclear.
FCRN member ffinlo Costain has published a response to the paper Climate change: ‘no get out of jail free card’ (summarised on the FCRN website here). Costain argues that biological methane emissions - such as those from grazing livestock - can be “warming neutral” as long as they fall by 10% by 2050. Citing Oxford climate scientist Myles Allen, Costain argues that sharply cutting ruminant numbers would only deliver a warming reduction of 0.1ºC at most, which would be outweighed within a few years by continuing carbon dioxide emissions.
In this debate piece, authors Pete Smith and Andrew Balmford argue that the recent development of the GWP* method of measuring the climate impact of short-lived greenhouse gases (notably methane), as opposed to the conventional GWP method, should not be used as an excuse to avoid reducing methane emissions. Read more about the differences between GWP* and GWP in the article New way to evaluate short-lived greenhouse gas emissions.
FCRN member Helen Harwatt has co-authored a letter calling for high- and middle-income countries to incorporate four commitments on livestock, emissions and land use into their commitments for meeting the emissions reductions of the Paris Agreement.
The FCRN’s Tara Garnett appeared on The Food Programme by BBC Radio 4 in the episode “Eating Animals Part 2: A Meat Q&A”. The programme also featured Patrick Holden of The Sustainable Food Trust and writer and environmental campaigner George Monbiot.
This book addresses sustainability problems in modern animal agriculture and proposes solutions on topics such as biotechnology, feed production techniques and disease management.
This book discusses how networks of wireless sensors could be used in African agriculture, e.g. to minimise conflicts between wildlife, people and livestock, or to monitor livestock health.
This book questions whether the rising demand for meat is indeed driven mainly by wealth and argues that the consumption of cheap meat is linked to economic insecurity. It also questions the view that the modern human brain evolved because of the consumption of meat.
This report by US think tank ReThinkX examines the implications of ongoing disruptions to livestock industries. It predicts that current livestock production will be replaced to a large extent by a “Food-as-Software” model, where food can be engineered on the molecular level and produced using “precision fermentation”, e.g. using engineered microorganisms to produce proteins that mimic milk proteins.
This report from environmental NGO Friends of the Earth US outlines the health, environmental, ethical and consumer concerns associated with research into genetically engineered livestock. It notes that gene editing can lead to unintended effects, such as unintended modification of portions of DNA, enlarged tongues in rabbits, extra vertebrae in pigs, and novel proteins produced in error (which could result in allergic reactions).
