Fixing hunger is as challenging as ever. Many food producers, including farmers, hunters and fishers are food-insecure; meaning they're not always sure where their next meal will come from. More than 50% of the roughly 600 million who are food insecure live in conflict zones. The risk that multiple misfortunes can cascade, such as a war in one region and crop failures in others, increase the stakes for the most vulnerable, who are generally hard-pressed to withstand a single hit to their food supplies, let alone several.
