PHL Varies Between States Within One Country (ADM Institute; 2012)
A More Specific Perspective:Rice in SE Asia (IRRI; 2011)
ConsumptionCrop
In SE Asia, physical losses range from 15-25%.
Quality losses range from 10-30% (loss in value)
Reducing PHL and Increasing YieldsHave 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
AGENDA
• Future food security challenges
• Several “views” of post-harvest loss

Measured harvest losses (3 Brazilian states)
Gathering information on storage conditions
Gathering information on tracking trucks
Identified farm for our silo bag feasibility test in June
Instituto Nacional de Pesquisas Espaciais
Gathering climate data for storability risk calculations
Measurement, Documentation and Postharvest Processing for the Prevention of Postharvest Losses of Soybeans and Corn (Danao, Gates, Eckhoff, Paulsen, Rausch)
Measuring pre-harvest, combine header, and threshing/cleaning losses
UFVUIUC UFGUFMT
Measurements from soybean harvest (February 2012) and corn harvest (July 2012) completed.
Using a standard method for measuring harvest losses developed by EMBRAPA,
faculty and students traveled from Jataí, Goaís to Sinop, Mato Grosso (1,034 km) to
conduct field measurements.

Quantity and quality loss assessments in graneleiros & trucks; exploring use of silo bags.
How can we increase efficiency in graneleiros?
Can silo bags serve as temporary storage?
How can we minimize losses during transport?
