Summary

The 2008-2011 food price spikes brought the issue of postharvest losses (PHL) back to the forefront of policy debate, and observers are again calling for a reduction in PHL as a tool to feed the expanding global population. Food losses due to improper postharvest handling, lack of appropriate infrastructure, and poor management techniques, have once again become a matter of serious concern. Food losses, defined as “any decrease in food mass throughout the edible food supply chain,” can occur in any point of the marketing stages–from production (e.g., crop damage, spillage), postharvest and processing stages (e.g., attacks from insect or microorganisms during storage), distribution, and retail sale until home consumption (e.g., spoilage, table waste) (Rosegrant et al. 2013). Kummu et al. (2012) suggest an additional 1 billion people could be fed if food crop losses were halved, which could potentially relieve some of the pressure on the significant increase in production that would be required. Achieving lower levels of food losses, however requires both investments in technologies that help prevent losses as well as in overall infrastructure. Understanding the magnitude of these investments and their impact is key to establish that a reduction in PHL has in fact an impact on food security.
