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.

In their latest dietary guidelines, the Chinese government recommends a slightly lower meat intake than it did in its previous 2007 guidance.

The World Resources Institute (WRI) has formed a partnership with major companies including Google, Sainsbury’s, Hilton Worldwide and other leaders in the food industry aimed at finding ways to encourage consumers to buy more plant-based foods.

The OneHealth project, launched in 2015, explores the relationship between infectious diseases, biodiversity and ecosystems, the economics of disease and disease drivers, and the impacts of climate change and demography on health.

In a digital studio at Harvard sixty people from 30 countries join Michael Sandel in this Radio 4 show, to discuss the philosophical issues underlying the world's response to climate change.

The newly elected Australian conservative government makes a clear break from the previous government – led by climate skeptic Prime Minister Tony Abott – after announcing more funding for climate science.
