This text looks at how climate change action affects farming and greenhouse gas emissions. It analyzes how producing food, bioenergy, or preserving nature compete for land, impacting food prices. The researchers studied different diets and farming methods and found that cutting out ruminant products could make reaching climate goals cheaper. They also created a model to understand how using land for bioenergy can impact prices. The study suggests that the total farmland available and bioenergy yields greatly influence food prices. Additionally, it highlights how limiting bioenergy production to less valuable land could be hard to put into practice. The researchers also investigated how high food prices can affect people in Sub-Saharan Africa, showing that most are net buyers of food and therefore susceptible to price changes.
