This study compared the impact that a 20 per cent sales tax and a 20 cents per litre excise tax on beverages such as carbonated non-diet soft drinks, cordials and fruit drinks would have on moderate and high consumers. It found that although high consumers of sugar-sweetened beverages have the least elastic demand, they drink so much that they are up against household budget limits, and therefore adding tax would bring down their consumption.

Volume 57.2 of Development - the quarterly journal of the Society for International Development - was produced in the lead-up to the Second International Conference on Nutrition (ICN2). It explores the relationship between nutrition, food security and sustainable agriculture.

Although not specifically focusing on food sustainability this paper is of relevance for the larger debate on alternative models of sustainable development. The paper concludes that our modern material lifestyles are failing to make us happier, are damaging our health, are no longer sustainable and cost the overall economy tens of billions of pounds every year.

Author summary This article provides a synopsis of the main research findings from the book “Environmental protection with knife and fork – the ecological rucksack of nutrition in Germany”, various peer-reviewed publications and as well as the underlying dissertation of the author. The first part of the article presents an overview of current challenges in the transdisciplinary field of nutrition, environment and public health. After a brief presentation of the methods, in the results section life cycle assessment results are presented on product and consumption levels and possible courses of action are derived – with a special focus on different diets and reduced food losses.

This special issue focuses on the implications of climate change for food safety. The introductory paper to the series briefly summarizes the current state of knowledge.   It states that:

This systematic review evaluates the environmental impact of 49 dietary scenarios and shows that shifts in consumption could reduce diet-related GHG emissions and land use demand by up to 50%. The paper states that the amount and type of meat in the diet mainly affects the improvement potential. The research also identifies and addresses research gaps and key methodological aspects influencing outcomes.

Due to the large share of non-CO2 GHGs in emissions from livestock production, the choice of GHG metric used to compare emissions of different GHGs is crucial, both in order to assess the aggregate contribution of the livestock sector to climate change and for highlighting hot-spots in the animal food chain where emission reductions can be most cost-effectively made.

A question that emerged from FCRN's previous discussions with various experts on animal farming was whether breeding for productivity and animal welfare can be aligned.

This paper, entitled Dietary quality among men and women in 187 countries in 1990 and 2010: a systematic assessment argues that although worldwide, consumption of healthy foods such as fruit and vegetables has improved during the past two decades, it has been outpaced in most regions by the increased intake of unhealthy foods such as processed meat and sweetened drinks.
