Why it's essential to feeding the world sustainably

  • Prevents food waste - explain how: it smooths out temporal mismatches of supply and demand.
  • Provides food security by having something available always
  • Consider how crop harvest productivity varies from year to year. Food preservation harnesses the long-term trend.

How it can be done

  • Dehydration
    • requires some energy input and/or land.[QUANTIFICATION needed]
  • Freezing
    • probably higher energy requirements[QUANTIFICATION needed] - depends how long it stays frozen for on average.[RESEARCH needed]
  • Canning
    • more packaging per unit food - might have a unreasonably higher resource footprint.[RESEARCH needed]
  • Pickling
    • not suited for the bulk of the diet (too much sodium).
