Key takeaways

  • Around the globe, an estimated 900 million people face hunger daily, more than 1.4 billion additional people lack vital micronutrients, and almost 40% of the population can't afford a healthy diet.
  • However, this issue is not evenly dispersed. When the price of food is raised, it largely hits lower-income countries the hardest and can lead to lower food security, acute shortages and, ultimately, social unrest.
  • Yet food is both a victim and a cause of climate change. Food systems need to adapt to a warming world; they need to be more resilient, feed more people, and also be sustainable.
  • Wide-ranging solutions are needed, from increasing consumer education about healthy foods to making healthy foods more affordable and accessible. Longer term, poverty and inequality need to be addressed, as does a scaling up of climate resilience.
