Abstract

Abstract To achieve responsible consumption and production under UN Sustainable Development Goal (SDG) 12, national agri-food consumption and production need to be assessed against environmental limits. We downscaled the Land-System Change planetary boundary and allocated national-scale environmental limits for cropland for agri-food consumption via fairshare allocation based on population, and for production via biophysical allocation based on available arable land. We assessed country-level utilisation of Land-System Change planetary boundary for cropland due to their cropland footprints. We quantified national consumption and production-based cropland footprints (including imports/exports) using an environmentally extended multi-regional input-output model and calculated the percentage utilisation of national environmental limits for cropland. Most countries' agri-food consumption footprints exceeded their fair-share cropland limit, but production utilisation of biophysical limits was less pronounced. For example, China and India were within their safe limit of consumption-based environmental limit for cropland with utilisation ratio of 80% and 74% respectively, but their utilisation ratio for production-based environmental ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
