Impacts on Food Security and Adaptation Options

  1. 1. Food security and adaptation Prof Mark Howden Vice Chair Working Group II Australian National University
  2. 2. Climate changes affecting crops differently IPCC 2014
  3. 3. More negative and less positive over time IPCC 2014 Climate changes affecting crops differently
  4. 4. Climate change impacts on Pacific crops Bell and Taylor 2015
  5. 5. Yield variability likely to increase IPCC 2014
  6. 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. 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 IPCC 2014
  8. 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” IPCC 2014
