Knowledge for better food systems

Showing results for: Global

While some of the food system challenges facing humanity are local, in an interconnected world, adopting a global perspective is essential. Many environmental issues, such as climate change, need supranational commitments and action to be addressed effectively. Due to ever increasing global trade flows, prices of commodities are connected through space; a drought in Romania may thus increase the price of wheat in Zimbabwe.

This paper analyses the Twitter reactions to the diet proposed by the EAT-Lancet Commission on healthy diets from sustainable food systems, focusing on the #yes2meat hashtag as well as the official #EATLancet hashtag. The study found a sizable countermovement that was sceptical of the EAT-Lancet dietary recommendations, with the #yes2meat term becoming prominent around one week before the EAT-Lancet report was launched.

This commentary reviews the evidence on climate tipping points - i.e. irreversible (on a human timescale) and abrupt shifts from one climate state to another - and concludes that several interlinked tipping points could be already active or very near to being triggered. Cutting emissions could still slow down the rate at which the tipping points operate, the authors argue.

In this blog post, Asaf Tzachor of the Centre for the Study of Existential Risk at the University of Cambridge describes four pathways by which the global food system could collapse. He calls for greater awareness that interactions between different processes (such as ocean acidification, climate change, wildfires and plant diseases) could lead to vicious cycles, and argues that policymakers should seek leverage points in the food system.
