Food Biomass Requirements

CanESS > Food Production > Food Biomass Requirements

Food Biomass Requirements calculates the mass of crops produced for human and animal consumption, quantities required for resource production and energy use calculations in other sections of the model. It comprises 3 procedures:

(1) Crop Use for Human Consumption

InputsOutputs
Canada total population (person) from Population crop for person food (tonnes/year)
crop food per capita (tonnes/(person*year))

Crop Use for Human Consumption takes Canada total population (person) from Population and crop food per capita (tonnes/(person*year)) to calculate crop for person food (tonnes/year). This is passed on to the calculators Recycled Vegetable Oil Available and Agriculture Land Biomass Disposition.

(2) Animals Fed

InputsOutputs
animals per capita (animals/(person*year))animal stock fed (animals/year) passed to Animal Fat Available
Canada total population from Population

Animals Fed uses animals per capita (animals/(person*year)) as well as Canada total population from Population to calculate the number of animals that require feeding. This is saved in the variable animal stock fed (animals/year) and is passed on to the calculator Animal Fat Available.

(3) Animal Feed Required

InputsOutputs
animal stock fed (animals/yearcrop feed for animals required (tonnes/year) passed to Animal Feed Byproduct Substitution
food per animal per year (tonnes/animal)pasture feed for animals required (tonnes/year) passed to Animal Feed Byproduct Substitution
total animal feed required (tonnes/year) passed to Fertilizer Production Energy Use and Animal Based Emissions

Animal Feed Required uses animal stock fed (animals/year) from (2) Animals Fed along with the required food per animal per year (tonnes/animal) to calculate the required amount of animal feed. This information is saved in 3 variables:
