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
- 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).
