FCRN member Dr Rosemary Green of the London School of Hygiene & Tropical Medicine has published a paper that calculates the greenhouse gas (GHG) emissions and water use associated with five dietary patterns in India. As shown below, GHG emissions per capita are highest for the “rice and meat” dietary pattern (at 1.2 tonnes CO2 eq. per year) and lowest for the “wheat, rice and oils” pattern (at 0.8 tonnes CO2 eq. per year). For comparison, per capita dietary GHG emissions in the UK have been estimated at 2.6 tonnes CO2 eq. per year for high meat eaters and 1.1 tonnes CO2 eq. per year for vegans (Scarborough et al., 2014). Water use is highest for the “wheat, rice and oils” pattern and lowest for the “rice and low diversity” pattern.

This paper reports on a systematic review of grocery store interventions undertaken to evaluate their effectiveness in changing food purchasing behaviours, and to examine whether this effectiveness varied with intervention components, setting, or socioeconomic status. This is the first paper to synthesise evidence from randomised controlled trials (RCTs) in grocery stores across a wide range of intervention types.

In this policy briefing “A Healthy and Sustainable Food Future Policy recommendations to embed sustainability in the Eatwell Guide and wider UK food policy” the Eating Better Alliance and Medact call on Public Health England (PHE), government more broadly and health professionals to do more to promote healthy and sustainable diets and to ensure that dietary recommendations underpin food and farming policy.

The authors of this paper compare the impact of intensification in the beef and dairy sectors via two pathways; either intensification within a system (e.g. a mixed crop-livestock system) or through transitioning to another more productive system (from pasture to mixed crop-livestock production) and assesses the mitigation potential that could arise.   It reviews the impacts of these forms of intensification on both GHG emissions, land occupation and land use change (LUC), the last of which has often been excluded in other similar analyses.  

Contemporary agriculture is often criticized for its industrial scale, adverse effects on nutrition, rural employment and the environment, and its disconnectedness from nature and culture. Yet there are many examples of traditional smaller scale systems that have survived the test of time and provide more sustainable solutions while still maintaining food security in an era of climate change. This book provides a unique compilation of this forgotten agricultural heritage and is based on objective scientific evaluation and evidence of the value of these systems for present and future generations.

In this Nature Comment article, Elena Bennett of the McGill School of Environment and the Department of Natural Resource Sciences, Québec, argues against the underlying premise of the ‘land-sparing’ vs ‘land-sharing’ debate that has dominated the agriculture-environment discourse for decades, and advocates a new and more holistic approach that focuses on maximising human well-being.

This new article published in Solutions, whose authorship includes several FCRN members, briefly outlines current food system issues. The work is based on discussions in the session ‘Sustainable nutrient management in the Anthropocene’ at the IARU Sustainability Science Congress 2014.

This report by the John Hopkins Center for a Livable Future presents itself as the ‘first international landscape assessment of industrial food animal production (IFAP) in low- and middle-income countries (LMICs) to focus on trends in food animal production, related domestic and international policies, environmental and public health impacts and animal welfare.’
