6. Food value chains: storage
• Increased need for postharvest drying,
refrigeration etc
• Potential shorter shelf life of perishable products
due to changes in product composition
• Local level: Farmers individual and collective
storage infrastructures
– flexible and cost-effective storage systems
• Global level: ongoing consideration of governance
options for food reserves
Rivera-Ferre (2014)
7. Value chain: distribution and exchange
• Damage to infrastructures (heat stress on roads,
increased frequency of floods)
• Ports damaged by flooding, extreme events:
fisheries, trade
• Decline in local production (or increased variability
in this) may reduce household capacity to engage
in traditional forms of exchange
• At the regional, national, global level, trade remains
a major factor in managing projected food security
issues
– institutional issues will continue to need attention
through WTO and other mechanisms
– shipping

8. Impacts, adaptation and barriers
“Barriers include access to
financial, technological, and
human resources; cultural and
social acceptability; political
and legal frameworks; the
emphasis on island
development as opposed to
sustainability; a focus on short-
term climate variability rather
than long-term climate change;
and community preferences for
‘hard’ adaptation measures
rather than ‘soft’ ones”

10. Dimensions of food security
FOOD SECURITY
Accessibility
Availability
Utilisation
Stability
FAO, GECAFS
Food availability is determined by the physical quantities of
food produced, stored, processed, distributed, and exchanged
