Global Food Demand Is Predicted to Increase 70% by 2050 (FAO; 2009)

Dietary changes in developing countries

Presenter
Presentation Notes
FAO prediction from “How to feed the world in 2050 (2009)” Prediction based on expert opinions in population, urbanization, and income growth, excluding the food demand for biofuels Food production must increase by 70% Annual cereal production: rise to 3 billion tonnes from 2.1 billion (43%) Annual meat production: rise by over 200 million tonnes to reach 470 million tonnes (74%) Arable land will be expanded by 70 million hectares (5%) Key Points – left hand side— Red is growth from 1965 to 2000 Green is projected growth from 2000 to 2030 ----right hand side – changing diets From rice to wheat More veg oils More meat

2030 Food Demands Require About 200 Million More Hectares (McKinsey; 2011)

Reducing PHL and Increasing Yields Have High Potential (McKinsey; 2011)

Presentation Notes
More than 80% of ag productivity gains need to occur in developing countries

Why Reduce Post-harvest Loss: Some Hypotheses (or Hallucinations?)

• 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 is in limited supply – reducing PHL can lessen pressure on scarce resources

Rice in SE Asia (IRRI; 2011)

Consumption Crop

In SE Asia, physical losses range from 15-25%.

Quality losses range from 10-30% (loss in value)

PHL in China (some scattered observations)

• PHL in grains is 18% (2% - 5% in storage) (1992)

• PHL in storage in villages is 8% to 10% (farmer storage is primarily through traditional methods) (2006)

• PHL higher in fruits & vegetables (2003) – Fruits; 20% to 25% – Vegetables: 30%

• PHL of rice in total exceeds 14%
