Writing in the Guardian, Isabella Tree of Knepp Castle Estate argues that vegan diets ignore the potential of wildlife-friendly livestock grazing methods. Tree claims that not using anti-worming agents or antibiotics allows cow dung to feed various soil organisms, contributing to soil restoration and wildlife diversity.
The FCRN’s Tara Garnett is featured in this video by UK climate website Carbon Brief, which discusses how farmers could reduce the carbon footprint of beef production. Tara points out that production-side measures only go so far, and that consumption changes are needed as well.
FCRN member Erasmus zu Ermgassen of the University of Cambridge has surveyed six NGO initiatives that are promoting sustainable cattle ranching in the Brazilian Amazon by using intensified pasture production to avoid deforestation. He finds that high-productivity cattle ranching is possible, requiring investment of US$410–2180/ha with payback times of 2.5–8.5 years. However, several barriers exist, including knowledge transfer, financial support and transparency in cattle supply chains.
Researchers from the University of Edinburgh have sequenced the genomes of 913 types of microbes found inside cows’ digestive systems, hoping to discover more about the types of enzymes that the microbes use to break down the food.
This study, undertaken by researchers at Michigan State University and the Union of Concerned Scientists, compares the net greenhouse gas (GHG) balance of two different beef finishing systems in the Upper Midwest, of the United States: a feedlot system; and a grazing system based on adaptive multi-paddock (AMP) grazing principles.
This paper by researchers from the USA, UK and Mexico examines the biodiversity conservation and carbon storage implications of a number of land-use scenarios related to cattle ranching in Yucatán, Mexico.
This study by researchers in the US used a theoretical approach to work out how much beef could be produced in the US if the cows were raised solely on pasturelands and by-products, and what the environmental and nutritional ramifications of repurposing the freed up cropland would be.
This new paper by FCRN member Elin Röös , the FCRN’s Tara Garnett and colleagues explores the following questions: What would be the implications, for land use and greenhouse gas emissions, if our global population moved away from eating beef and other ruminant meats and switched mostly to chicken? What if we all went vegan? What if all our meat demand were met by artificial meat? Or what if, in an attempt to avoid ‘feed-food’ competition, we limited our consumption of animal products to what we could obtain by rearing animals on grasslands and feeding them byproducts and food waste?
The WCRF has released a report on colorectal cancer as part of its Continuous Update Project (CUP) – an ongoing programme to analyse global research on how diet, nutrition, physical activity and weight affect cancer risk and survival. The report confirms that, along with other risk factors, consuming red and processed meat increase the risk of colorectal cancer.
This study by FCRN member Helen Harwatt and colleagues seeks to determine whether simple dietary changes can make a meaningful contribution to greenhouse gas (GHG) mitigation efforts, by considering a very simple example of US consumers substituting beans for beef in their diets. The study uses available life cycle assessment (LCA; see Chapter 2 of foodsource) data to predict the change in GHG emissions that would be associated with a substitution of beans for beef (substitution on the basis of calories, and on the basis of protein content). They place these projected changes in the context of US 2020 GHG reduction targets.
The world’s largest agricultural commodities supplier, Cargill, obtained its highest profit in six years based on an increasing demand for meat. Animal nutrition and protein were the largest contributor to quarterly earnings for the company.
This report, by the US based NRDC (The Natural Resources Defense Council) finds that the per capita diet related carbon footprint of the average US citizen decreased by 10% between 2005 and 2014, driven by a 19% decrease in beef consumption.
In this paper, using three scenarios for food demand, the researchers model and highlight the indirect relationship between greenhouse gas (GHG) emission abatement within the food supply system and the energy system, globally.
The Global Roundtable for Sustainable Beef (GRSB), a global, multi-stakeholder initiative developed to advance improvement in sustainability of the global beef value chain, held a conference in October 2016.
An academic debate on the controversial possibility of decreasing greenhouse gas emissions via increased beef production in the Brazilian Cerrado finds a new set of commentators, who have responded to an original paper by de Oliveira Silva et al. earlier in 2016 in the same journal, Nature Climate Change.
