Future demand for food and for land is set to grow. A key question is therefore: how can we most productively use land for food, in order balance the multiple competing demands for the ecosystem services it provides? One way this has been investigated previously is by looking at crop yields and how to increase them. Another way, focussing instead on the consumption side, has looked at the metric of dietary land footprint.

Taking as their starting point a hypothetical zero-deforestation for agricultural production, where people would refrain from clearing any further forests for agricultural purposes, the researchers behind this study look at both supply side and demand side measures to assess how changes in production and diet can assist in halting deforestation

This study, which quantifies at the global and regional level the health and environmental consequences of dietary change,  argues that there are substantial health and environmental gains to be made from switching to more plant based diets.  According to the research, food-related emissions could be cut by 29% if global dietary guidelines were adopted. 

This study examines how a shift to lower environmental impact diets (diets with less meat and dairy) might the affect nutrient intakes of young children in the Netherlands.  It is unusual in that it looks specifically at children, rather than adults or the general population.

The Swedish environment and sustainability magazine Miljöaktuellt has carried out a survey of municipalities in Sweden which show that 4 out of 10 schools have implemented either a meat-free day a week or undertaken other activities that reduce meat consumption to an equivalent degree.  This number of participating schools represents an increase of 35% from the previous year.

Germany has traditionally been a country with high meat consumption per capita, but a new study shows that young Germans are increasingly turning to vegetarian diets. The study market analyst company Mintel followed 1,000 people aged over 16 and their results show that nearly one in five (18%) Germans aged between 16 and 24 purchase meat-alternative products. This is comparable to the one in ten (11%) doing the same across all age groups.  A major challenge for this trend to consolidate however, is that only 14% of Germans say that they enjoy the taste of these products.

The launch of the new vegetarian alternative to the meatballs – grönsaksbullar - is what Ikea calls “the first step to include a wider variety of healthier and more sustainable food choices”.

This paper investigates the environmental impact of the diets of Australian households at different income quintiles. The paper looked at 2003 household consumption and argues that income affects the environmental impacts of household diet, with higher income corresponding to higher impacts. The higher the income bracket the more was spent on food and this translated through to a higher environmental impact (GHG CO2e, water, waste, energy) at higher incomes.
