Why Reduce Post-harvest Loss?Why Reduce Post-harvest Loss?Some HypothesesSome Hypotheses
• Estimates suggest 1/3 of agricultural production is “wasted” and doesn’t reach food consumer
• Investment required to reduce PHL could be modest
• Technology advances should make reduction more feasible and less expensive
• Arable land, water, energy are in limited supply – reducing PHL can lessen pressure on scarce resources

??How?? Did Change Occur???How?? Did Change Occur?
• Parents never took the Econ 101 class
• But changes to reduce loss did occur
– Availability of effective technologies/Financial capability --- necessary, not sufficient
– Local experience w/ adaptation– Multiple, credible, confirming sources of info– Assurance of technical support – Organizational innovation

Summary ThoughtsSummary Thoughts
• The art of loss-free agriculture begins with understanding the farmer’s & manager’s perspective
• of “loss” that can be converted to gain
versus
• “loss” which is a cost of doing business.
• Urgent need is research & engagement focused on:
Why farmers don’t employ the proven and relatively simple technologies and practices that are known to reduce loss?
