.set_no_stored_food

source

.set_no_stored_food(
   constants_for_params
)

Sets the stored food at start of simulation to zero.

.set_baseline_stored_food

source

.set_baseline_stored_food(
   constants_for_params
)

Sets the stored food at start of simulation to the expected amount in the start month.

.set_stored_food_buffer_zero

source

.set_stored_food_buffer_zero(
   constants_for_params
)

Sets the stored food buffer as zero -- no stored food left at the end of the simulation.

However, in reality food in transit and food in grocery stores and warehouses means there would still likely be some food available at the end as a buffer.

.set_no_stored_food_between_years

source

.set_no_stored_food_between_years(
   constants_for_params
)

Sets the stored food between years as zero. No food is traded between the 12 month intervals seasons. Makes more sense if seasonality is assumed zero. All expected stored food at start is however available.

However, in reality food in transit and food in grocery stores and warehouses means there would still likely be some food available at the end as a buffer.

.set_stored_food_buffer_as_baseline

source

.set_stored_food_buffer_as_baseline(
   constants_for_params
)

Sets the stored food buffer as 100% -- the typical stored food buffer in ~2020 left at the end of the simulation.

.set_stored_food_buffer_as_baseline_and_no_stored_between_years

source

.set_stored_food_buffer_as_baseline_and_no_stored_between_years(

source

Set the fish percentages in every country (or globally) from baseline although this is a global number, we don't have the regional number, so we use the global instead.

This data comes from reading the graph off of this figure in the following paper: Global food insecurity and famine from reduced crop, marine fishery and livestock production due to climate disruption from nuclear war soot injection https://www.nature.com/articles/s43016-022-00573-0/figures/2 Specifically, plot b.
