Food Losses:
Losses in production (including PHL), distribution, and
processing.
- More prevalent in developing countries
- Representative samples of farmers, middlemen and
processors
Food
Waste
- More prevalent in
developed
countries
- Not covered
3. Evidence from China, Ecuador, Ethiopia,
Guatemala, Honduras and Peru
โข Food losses are substantial
(6% - 26% of production)
โข Especially when we account for
quality losses
โข Most of the losses occur at the farm
level (56% - 86% of losses)

In the field?
Post Harvest at farm?
Transportation and
storage?
Processing?
Most of the losses occur
at the farm level (56-86%)
5. Determinants vary by crop, context, and
production stage
Main determinants:
- weather
- poor knowledge of how to avoid pests & plagues
- poor technology (no mechanization, low quality seeds)
- poor infrastructure (storage, transportation, processing)
- low and volatile prices

6. Less food loss = higher farm income?
โข Yes:
- by definition if preventing food loss as quality loss (lower value)
- much, if not most of losses happen at the farm level
โข Depends:
- If โsavedโ food can be sold in market (without price loss)
- More likely if food loss prevention through
- improved handling, packaging on farm (sealed bags, crates, etc.)
- adequate storage (dry and cold chains)
- adequate transportation
- greater processing capacity
- certification of food quality/safety and contractual arrangements
- Even more so, above also helps reduce market price volatility
โข But:
- Cost of technologies/interventions should not be prohibitive
- Thinks need to work along the entire supply chain
7. Less food loss = crop substitution?
โข We do not know
- Little evidence about patterns of crop
substitution in response to reductions in food
loss
โข Depends on
- the extent of adoption of new technology and
demand elasticity of crop
- shift to higher value added crops (e.g. fruits
and vegetables) more likely if also cold chains
are also developed
8. Less food waste =
lower prices and farm
incomes?
โข We do not know
- Little evidence
โข YES
- If significant food waste reduction, prices would drop and farm incomes may
drop for that food product (ceteris paribus)
โข BUT
- Consumer purchasing power would rise and demand could shift to higher value
added foods
- Impacts on nutrition outcomes could be ambiguous
- Impacts on environmental pressures could be ambiguous
9. Reducing food
loss cannot be
sole focus
โข There are simple solutions reducing food
loss, but benefits not always around the
corner
โข Farm level benefits require full value
chain development and market access
โข Income and nutritional gains will
depend on broader food system
improvements
โข Environmental gains not achieved by
just reducing food loss; agriculture and
food systems at large need to be made
sustainable
Hinweis der Redaktion
Improvements to measurement:
Consider the agricultural process as a whole (pre-harvest, harvest, and post-harvest losses).
Value chain approach (farmer, middlemen, processor)
Not only lost quantities, but also gauge economic value of quality deterioration along different nodes of the value chain
Identify most frequent reasons of losses
Measure scrapped food both discarded and poor quality).
Howeverโฆ food is also scrapped due to:
- Management problems during pre-harvest (field fungal infections in beans / wheat, earworm affecting maize cobs, etc.)
- At harvest (split potatoes due to poor harvesting techniques)
- Unharvested production (low prices, high labor costs around harvest time)
