Performing full life cycle assessment on foods and diets is a data- and resource-intensive undertaking and as a result many studies tend to adopt a simplified approach, for example by limiting the number of food studied (in the case of diets), using proxy data, or limiting the system boundaries (cradle to farm gate; cradle to retailer – ie. not the full cradle to the consumer’s mouth).

Do you have 10 minutes to help Dr Arianna Psichas with a survey exploring people's views on the purchase and consumption of high-protein foods?

Researchers from Conservation International have found a small island near Timor-Leste with staggering species richness. Atauro Island, home to about 8,000 people sits in the middle of the so-called Coral Triangle, known for its biodiverse marine environments.

This report commissioned by the Committee on World Food Security (CFS) and written by its High Level Panel of Experts for Food Security and Nutrition (HLPE) focuses on sustainable agricultural development for food security and nutrition, specifically in relation to livestock.

As agricultural production of high-yielding cereals has increased over the past half-century, production of more nutrient-rich cereals has declined. Access to food of high nutritional quality is profoundly important, especially for the 2 to 3 billion people who are undernourished, overweight, or obese or deficient in micronutrients.

These two studies discuss afforestation projects in relation to 1) land availability and sheep farming in Scotland, and 2) the biodiversity losses that may be associated with such projects.

A new study published in the journal Nature Communications provides additional evidence that a specific group of controversial pesticides, neonicotinoids, affects wild bees negatively. The work was funded by the UK government and related data of wild bee distributions over time to the introduction of the pesticides in British fields. It is the first to link the pesticides to the decline of many bee species in real-world conditions.

The Global BMI Mortality Collaboration presents results in the Lancet from the largest pooled dataset on the relationship between weight and mortality rates. The analysis shows that both overweight and obesity in otherwise healthy participants were associated with increased mortality from all causes.

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.
