.TH Concept Food
.s3
In Empire, as in the "real" world, everyone must eat to survive,
(see SPECIAL NOTE below for the exception).
Each civilian or military eats 0.0005\"eatrate
units of food per time unit,
(i.e. 0.024 units of food a "day" in non-Blitz Empire).\"eatrate*86400/s_p_etu
.s3
The ability of a sector to grow food is indicated by its "fertility".
Fertility values range from 0 to 100.
.s3
Food can be grown in any kind of sector although agribusinesses
are able to grow more food with fewer workers.

.s1
Every sector produces a base level of food according to the following:
.in +0.2i
.s1
The amount of food that the sector can grow in one time unit is:
.s3
.ti +0.3i
fertility * 0.002\"ofgrate
.s1
The amount of food that can be harvested in one time unit is:
.s3
.ti +0.3i
(civilians + military / 5) * 0.002\"ofcrate
.s3
i.e. one civilian can harvest four times\"ofcrate/eatrate
the amount that he/she eats while
one military can harvest 4/5\"0.2*ofcrate/eatrate
of the amount that she/he eats.
.s3
Note that this means that although a sector with a fertility of 40
can grow enough food to support 160 people\"40*ofcrate/eatrate
at least 10 of them must be civilians.
In fact, any combination of civilians and military that meets the following
two criteria will be self-sustaining:
.s1
.ti +0.3i
civilians + military \(<= 4 * fertility\"ofgrate/eatrate
(amount that grows)
.s3
.ti +0.3i
military \(<= 15 * civilians\"(ofcrate/eatrate-1)*5
(amount that gets harvested)
.in \\n(in

.s1
In an agribusiness an \fIadditional\fR amount of food can be grown.
That amount is calculated by the following:
.in +0.2i
.s1
An efficiency factor (effact) takes into account the state of repair
of the agribusiness itself (sector efficiency, effic) and
the educational level of your farmers (the national education level, elev):
.s3
.ti +0.3i
effact = (effic * (elev + 10)) / (100 * (elev + 20))
.s3
The amount of additional food that the sector produces in one time unit is:
.s3
.ti +0.3i
(civilians + military / 5) * effact * fertility / 1000.
.s1
e.g. in a 100% agribusiness with a fertility of 50 and an educational level
of 10 the efficiency factor is 2/3; one civilian can harvest 0.033
units of food per time unit beyond the food produced normally in that sector
which is enough to support thirty-three other
people while one military can harvest 0.0066,
enough to feed thirteen other people.
.s1
The amounts of food cultivated by 10 civilians in 10 time units in a 100%
agribusiness are:

SPECIAL NOTE:  Residents of a sanctuary are verrry spiritual and are so
in tune with the universe, spacetime, and left-brain* that they need
no food to survive; thus no one ever starves in a sanctuary.

.s1
On a ship the following applies:
.in +0.2i
.s1
The amount of food that can be produced on a fishing boat in one time unit is:
.s3
.ti +0.3i
civil / 100. * fertil / 100.
.s3
The amount of food that can be produced on any other ship in one time unit is:
.s3
.ti +0.3i
0

.s1
The presence of food also affects the birthrate in Empire; if there is no
food in a sector no babies will be born.  A baby consumes 0.3\"babyeat
units of food in growing to adulthood.  But babies are only allowed to eat
half the food in a sector.
Thus if a sector could produce 25 new
civilians but only has 2 spare units of food, (after the current population
has eaten), three babies will be born and one unit of food will be left.
