According to the World Food Programme, ripple effects of the Covid-19 pandemic and the war in Ukraine have contributed to one of the worst food crises in decades, with acute food insecurity affecting 200 million more people globally than in 2019 due to rising costs of food, fuel and fertiliser.
As the global population passes 8 billion and is predicted to reach 10 billion by 2050, farmers, governments and scientists face the challenge of increasing food production without exacerbating environmental degradation and the climate crisis, which itself contributes to food insecurity in the global south.
The United Nations projects that food production from plants and animals will need to increase 70% by 2050, compared with 2009, to meet increasing food demand. But food production is already responsible for nearly a third of carbon emissions as well as 90% of deforestation around the world.
“We use half of the world’s vegetative land for agriculture,” said Tim Searchinger, a researcher at Princeton University. “That’s enormously bad for the environment. We can’t solve the current problem by moving
