Food security…
... exists when all people, at all times, have physical, economic and social access to sufficient, safe, and nutritious food to meet their dietary needs and food preferences for an active and healthy life.
(UN-FAO World Food Summit 1996, 2012)
… is universally applicable
… is more than food production
… is underpinned by food systems

Food System challenges are interconnected
against a background of stresses and shocks
natural resource depletion
and
many stagnating rural economies
and
changing climate
and
social and socio-cultural changes
To achieve food security for a growing, wealthier, urbanising population while minimising further environmental degradation
![Page 27: Enhancing Food Systems Resilience ANU 2018.pdf · •Soil degradation ... => Final Cals/Nutrient Quantity and Price at shop Productivity Diversity & Quality ... wealthy nations consuming](https://reader036.fdocuments.us/reader036/viewer/2022070801/5f029cc27e708231d40521e4/html5/thumbnails/27.jpg)
“The capacity over time of a food system and its units at multiple levels, to provide sufficient, adequate and accessible food to all, in the face of various and even unforeseen disturbances.” – just relates to Food Security
So what is
‘Food System Resilience’?
Enhanced understanding needed to:
accommodate different perspectives looking at a common problem (esp. concerning multiple societal goals)
be based on use of evidence in a value-laden debate

4. Over what time period?
• Short-term interruptions (usually due to shocks) to eg:
• Fishing or agricultural activities (due to e.g. extreme weather)
• Critical ingredient shortfall (due to e.g. disease outbreak)
• Just in time groceries delivery (due to e.g. IT malfunction)
• Consumer shopping patterns (due to e.g. food scares)
• Longer-term disruptions (usually due to stresses) to eg:
• Natural resource degradation
• Energy price
• Low-carbon emission regulations
• Change in dietary preferences

Growing volatility from stressors and shocks needs enhanced resilience
3 Resilience notions
1. Robustness Aim to resist disruption to current outcome
2. Recovery Aim to return to current outcome after disruption
3. Re-orientation Accept alternative outcome after disruption(transformation)
All involve
Re-organisation Make changes to the system(adaptation)

Providing a healthy, affordable,

for all people will require a
radical transformation of the
system.
This will depend on:
better farming methods,
wealthy nations consuming
less meat and
countries valuing food which is
nutritious rather than cheap.
