Researchers at the Johns Hopkins Center for a Livable Future (CLF) have developed an Excel spreadsheet that can assist in calculating the nutrient value of food that is wasted. 

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.

This collection of papers in the journal Global Food Security assesses the situation of food security and the implications of food security governance on people’s lives in several Latin American countries, using experience-based food security scales questionnaires (EBFSSs). Ultimately these papers seek to address deficiencies in food security governance and put forward the case for more empirical research into the subject. The authors argue that improving food security governance in the region is complex but of the utmost importance. This would require improved cross-sector coordination and household (in)security monitoring through empirical measures such as EBFSSs.

This book contains six chapters on food security and sustainability in the Middle East. The book can be purchased in its entirety or by chapter online.

In this opinion piece, Edward Parson of the Emmett Institute on Climate Change and the Environment, UCLA, argues that Climate Engineering (CE) must urgently be given greater and more serious consideration within climate change research and policy, and calls upon the IPCC to take responsibility for this.

This paper describes an online choice experiment to understand consumer preferences around best-before dates, appearance, and packaging of food products; the paper specifically studies the demand for discounted ‘suboptimal’ products in the supermarket, and consumers’ willingness to use them in the home. 

Eating Better, an alliance of British organisations working together to help people move towards eating less meat and dairy, has published a policy report entitled ‘Beyond the CAP: policies to support better UK meat and dairy production post-Brexit’.

After a 25 year wait for approval, approximately five tons of genetically modified (GM) salmon have been sold in Canada in the last few months. The fish, which contains genes from Chinook salmon and ocean pout, can grow twice as fast as an Atlantic salmon and requires 75% less feed to grow to the same size. These changes can ultimately reduce the carbon footprint of each genetically modified salmon by up to 25 times, the company claims.

Maple Leaf Foods, one of Canada’s largest food manufacturers, has declared that it wants to become “the most sustainable protein company on earth”. With aims to improve nutrition, environmental sustainability, animal care and corporate responsibility, CEO Michael M. McCain released a statement saying that “Our food system has drifted from its roots, to nourish wellbeing, to farm sustainably, to view food as a universal good for all. We must serve the world better.”
