A perspective paper published by Environmental Research Letters revisits the 2004 study by Pacala and Socolow that deployed seven wedges of different existing energy technologies to address climate change. At the time of that paper’s publication, each wedge would avoid one billion tons of carbon (1 GtC) emissions per year after 50 years. In this new perspective paper, its authors show that as a result of increased emissions, merely achieving what was considered "business-as-usual" in 2004 would require the development and deployment of 12 wedges; stabilizing emissions at current levels would require another 9 wedges; decreasing emissions to the level needed to prevent climate change would need an additional 10 wedges. Altogether, 31 wedges would be required to stabilize the Earth's climate.

A new study from the Swedish University of Agricultural Sciences (SLU) and Future Forests shows that mixed forests, in comparison with monocultures, have positive effects on several different areas, including production. The study, which was published in the journal Nature Communications, is based on material from the Swedish National Forest Inventory and the Swedish Forest Soil Inventory and examined the relationships between multiple ecosystem services and both tree species richness and tree biomass in boreal and temperate forest. By examining the role played by the occurrence of diverse tree species for six different ecosystem services (tree growth, carbon storage, berry production, food for wildlife, occurrence of dead wood, and biological diversity), the study demonstrates that all six services were positively related to the number of tree species.

The UK Energy Research Centre (UKERC), in collaboration with the Glasgow University Media Group and Chatham House has released findings from a qualitative study of audience beliefs and behaviours in relation to climate change and energy security. 

The latest issue of the journal Proceedings of the Nutrition Society features a number of articles related to food, nutrition, and sustainability (including one by the FCRN’s founder, Tara Garnett).

A new book entitled “Principles of Sustainable Aquaculture: Promoting Social, Economic and Environmental Resilience” by Stuart W. Bunting of the Centre for Environment and Society at the University of Essex serves as an advanced level textbook focusing on developing more sustainable aquaculture practices. 

In this systematic review published in the journal PLOS Medicine, researchers investigated the association between food pricing strategies and food consumption and non-communicable diseases by analyzing the results of published mathematical modeling studies of food pricing interventions.

A study regarding the efficiency of beetle larvae (mealworms) as a potential protein source was published in the journal PLOS ONE by researchers at the University of Wageningen in Netherlands. The researchers compared the environmental impact of meat production on a mealworm farm to traditional animal farms using three parameters: land usage, energy needs, and greenhouse gas emissions. From the start of the process to the point that the meat left the farm, they found that mealworms scored better than the other foods. Per unit of edible protein produced, mealworm farms required less land and similar amounts of energy.
