Reuben Fellow Fredi Otto and her co-author, DPhil student Jasper Verschuur, wrote an opinion piece in The Conversation to explain their analysis of the case of the 2007 food crisis in Lesotho and explore its connection to climate change.
"Food security is a growing concern globally, with two billion people being subject to moderate to severe food insecurity in 2019 according to the United Nation’s Food and Agriculture Organisation. Food security consists of four interconnected pillars: food availability (how much is produced), food access (can people afford food), food use (how is food prepared and consumed) and stability (how stable is the food supply and consumption)...
...So far, scientists have mainly focused on estimating how climate change has affected droughts and agriculture yields. It’s less well known if and how climate change is influencing the other three pillars of food security."
