Value chain
Production quantity and estimated postharvest losses in % per value chain step. Please note that once loss has occurred at harvesting, the percentage loss in the next stage is a percentage of what remained, not of the original amount.

Nutrition
Number of people whose annual dietary requirements (in terms of energy, kcal) could have been met by consuming the maize that was lost postharvest, and what % of the focal group of the population this number equates to.
