The Three Key Messages for
World Food Day 16 October 2013
1. Good Nutrition depends on Healthy Diets
2. Healthy diets require Healthy Food Systems –
along with education, health, sanitation and
other factors
3. Healthy Food Systems are made possible by
appropriate policies, incentives and governance
Question: How to assess and monitor
Sustainable Healthy Food Systems?

or are some more equal than others...??

FAO Food Security Index – For the Future (1)

Data Collection
 Standardization of Methodology,
 High Frequency to capture seasonality and vulnerability
 GPS and Mobile Phone Technology
 Cost

Choice of Suite of Indicators
 Problem of Weightings and Evolution of the 4 elements of FS
 Appropriate to the Level – National, Household, Individual
and Target Populations
 At-risk groups: early life malnutrition, elderly, HIV, poor..
 To add Losses & Waste, Food Safety, Micronutrients
 Health Outcomes: BMI, NCDs...
 Coping Strategies – Cultural Dependency
 Sustainability

 Data Analysis and Presentation
 Ability to Aggregate & Disaggregate data
 Between Countries (Fixed) and Within countries (Flexible)
 Geo-spatial methodologies
 Monitoring & Evaluation


Validity (corresponds accurately) – problem of ‘gold standard’
Reproducibility (test-retest)
Cross-cultural comparability
Predictive Power
 Conclusion: FAO as the natural, “neutral broker” to lead &
coordinate a comprehensive Food Security Index along the
whole Sustainable Healthy Food System – from Farm to Fork

Some Questions for Sustainable Food Security / Systems (SFS)
At National Level
 Under what framework to integrate the many discipline - Agriculture,
Health, Environment – involved in Sustainability?
 How can Bio-Technology / Bio-Fortification help improve Food Security?
 How will external issues affect Food Security – such as a) Globalization; b)
Urbanization; c) Biodiversity; d) Climate change?
 What should be the criteria for incorporating & prioritizing short and longterm SFS in national policies
At Household Level
 How can communication and information technology be used to improve
data collection?
 What strategies can a) Increase and improve food production; b) Facilitate
access ; c) Reduce food losses and waste?
At Individual Level
 How to best assess SFS for different groups – farmers, rural women,
consumers, special needs vulnerable groups?
 Use of Mobile Phones for monitoring Food Security
 How to improve Behaviour change (education) and Coping skills in
culturally sensitive ways?
