The scale of post-harvest food loss is tragic. Nearly one-third of global agricultural production never makes it to the consumer or arrives in poor condition. Beyond the threat to food security, post-harvest losses adversely affect farmers and consumers in the lowest income groups. And, post-harvest food losses are a waste of valuable farming inputs, such as water, energy, land, labor, and capital. Having lived in East Africa earlier in my life, I saw the magnitude of post-harvest food losses in that region, and the tragic repercussions for human hunger, loss of farmer income, and harm to economic growth.
