food price spike 08 09 highlights 2 critical issues
Food Price Spike 08/09 highlights 2 critical issues
  • High levels of hunger & malnutrition in developing world
      • 1,020M undernourished: 195M U5s stunted
      • aggravated by price spike & current economic problems
  • Future shocks & challenges for agriculture
four transitions facing agriculture
Four Transitions facing Agriculture
  • From oil & gas for energy & fertiliserto renewables
    • Cost of energy, N fertiliser set to rise
  • From wasteful to sparing use of copious & free irrigation water
    • Water is getting scarcer
  • From high emissions of greenhouse gases (GHG) to neutral or even negative net emissions
    • Agriculture emits 17 to 32% of GHG, incl. land use change
    • Scope to lock C into soil, biomass
transitions con d from current to altered climates
Transitions (con’d)From current to altered climates
  • Hotter, more frequent extreme events, altered rainfall
  • Raised sea levels, reduced & more variable river flows, changed incidence of pests & diseases
  • Few sectors more affected than farming.
  • Most projections see overall reduced yields to agriculture
future agricultures
Future Agricultures?
  • More efficient & economical use of water & fertiliser
    • Better information technology and pricing will help;
  • Timely agriculture: prompt response to more variable weather
    • Information technology can help
  • Much reduced emissions through:
    • Better management of N fertiliser, manure
    • Less tillage
    • Drain rice paddies
    • Reduced stocks of ruminant livestock [?!]
    • Store C in soil and biomass
  • What would farming look like with C taxes on food?
  • NB: Climate-friendly = Pollute, Degrade Less
local production food security
Local Production & Food Security
  • Trade helps! Why?
    • Produce where water, fertiliser use most economical, emitting less GHG ...
      • ... Not necessarily where consumers live
    • To cope with increased variability of harvests
  • Transitions ...
    • If not made, who suffers most? ...
    • Most important for poor & small farmers ... &
    • To reduce poverty & hunger
