3. Professor Tim Lang,
who developed the idea
of ‘food miles’ has called
this a POLYCRISIS: a
combination of many
individual crises.
What are these
individual factors?
Which are short-term
and which will be longer
term problems?
4. 1. Climate change
• Caused unpredictable
weather including last
summer’s drought
• Affecting crop yields
around the world, leading
to food insecurity
• Increasing risk of plant
diseases in warmer
weather
5. 2. War in Ukraine
• Increased price of
fertiliser
• Increased price of grain
and oils which are fed
to animals
• Increased price of oil
and gas
6. 3. Last summer’s
drought
• Crop yields were lower
than usual
• Some crops damaged
by fire
• Grass was affected
meaning higher food
costs
7. 4. Recent bad weather
in Africa and Spain
• Bad weather damaged
salad crops including
tomatoes, peppers and
cucumbers.
• Due to high energy
costs these are not
being grown in the UK.
8. 5. Panic-buying
• When people start to
hear of shortages they
go out and buy more
than they need which
leads to shortages and
gaps on shelves –
rationing by shops
feeds this fear.
9. 6. Increased wage
costs / strikes
• Workers are asking for
more money: this will add
to costs for retailers.
• Strikes by lorry drivers and
train drivers affected the
distribution of food and
also led to closures by
cafes which served
commuters and office
workers.
10. 7. Some hangovers
from COVID19
• Increased demand for
cardboard due to rapid rise in
home deliveries of clothes,
books etc. as shops were
closed
• Global shipping affected
causing disruption to supply
chains
• Demand for resources around
sanitiser, masks, vaccines
etc. diverted from food
11. 8. Brexit
• Workers who provided labour
on farms returned home
(many during COVID) and
were not tempted back by
contracts available.
• Food rotted in fields for lack
of workers
• Increased paperwork
increased the cost of
importing food from the EU
12. 9. Avian Flu (HPAI /
H5N1)
• Millions of birds have been
culled due to bird flu
• Increased need for antibiotics
as a preventative measure (and
suggestions of a vaccine)
• Increased costs as free-range
flocks had to be kept indoors
and eggs sold as barn eggs.
13. 10. Supermarket
culture
• Supermarket contracts lead
to a lack of flexibility and little
competition (which would
lower costs) e.g. lettuce
prices stay the same so no
incentive to produce more in
a shortage
• If UK doesn’t increase price,
then available stock goes to
the EU instead
• No government intervention
14. 11. Energy & fuel
costs
• Increased costs of transport
• Increased costs of
refrigeration / lighting in
shops and distribution
centres.
• Increased costs for farmers
• Fertiliser manufacture is
energy-intensive.
15. 12. Timing
• This is a period when there
are few crops ready for
harvesting in the UK and
we have lost the habit of
keeping food by means
such as pickling, preserving
etc. due to year-round
availability
16. 13. Rural crime
• Cost-of-living problems
leads to thefts of food
crops from fields
• Farmers see increased
problems with crime when
people are desperate (also
thefts from supermarkets
rise).
