Global Food Demand Is Predicted to Increase 70% by 2050 (FAO; 2009) Per capita food consumption
3500 3000 2500 2000 1500 1000 500 0 1964/66 World Industrialized countries 1964/66-1997/99 Growth Developing countries 1997/99-2030 Growth
Dietary changes in developing countries
2030 Food Demands Require About 200 Million More Hectares (McKinsey; 2011)

PHL Varies Between States Within One Country (ADM Institute; 2012) Estimated post-harvest loss of black gram in India
25,28% 22,68% grading & repacking transport storage threshing drying harvesting Maharashtra Madhya Pradesh
A More Specific Perspective: Rice in SE Asia (IRRI; 2011) Crop
In SE Asia, physical losses range from 15-25%. Quality losses range from 10-30% (loss in value)
Consumption
Reducing PHL and Increasing Yields Have High Potential (McKinsey; 2011)
Little Attention Is Devoted to PHL and Yields (McKinsey; 2011)
Why Reduce Post-harvest Loss?
Some 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

Timeline of the ADM Institute
Fall, 2010 Jan 19, 2011 Feb, 2011 Initial conversations Official announcement & celebration $10 Million gift India/Brazil emphasis Staple crops Seed research efforts initiated $0.4 million in funding allocated Visioning processes Mar /Jul, 2011 Fall, 2011 RFP issued $2.1 million in funding allocated Throughout 2011 – Prospecting for collaborating entities
The ADM Institute for the Prevention of Postharvest Loss Vision Statement Key elements include:
•
To be an international information and technology hub
•
To encompass technologies, practices and systems
•
To focus on staple crops in key agricultural domains
Research Themes
Measurement & technology development Systems informatics & analysis Policy analysis Education, training, & information transfer
