                                Concept : Food

In  Empire,  as  in the real world, everyone must eat to survive, (see SPECIAL
NOTE below for the exception).  All of these  numbers  below  are  subject  to
change.  Execute the version command to get some of this information.  Ask the
deity for the rest.

Each civilian or military eats 0.0005 units of food per time unit, (i.e. 0.024
units of food a day in non-Blitz Empire).

The ability of a sector to grow food is indicated by its fertility.  Fertility
values range from 0 to 100.

Food can be grown in any kind of sector although agribusinesses  are  able  to
grow more food with fewer workers.

Every sector produces a base level of food according to the following:

                                Concept : Food

  The amount of food that the sector can grow in one time unit is:

     fertility * 0.002

  The amount of food that can be harvested in one time unit is:

     (civilians + military / 5) * 0.002

  i.e.  one  civilian can harvest four times the amount that he/she eats while
  one military can harvest 4/5 of the amount that she/he eats.

  Note that this means that although a sector with a fertility of 40 can  grow
  enough food to support 160 people 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-sufficient:

     civilians + military <= 4 * fertility (amount that grows)

     military <= 15 * civilians (amount that gets harvested)

                                Concept : Food

  In  an  agribusiness an additional amount of food can be grown.  That amount
  is calculated by the following:

    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):

       effact = (effic * (elev + 10)) / (100 * (elev + 20))

    The amount of additional food that the sector produces in  one  time  unit
    is:

       (civilians + military / 5) * effact * fertility / 1000.

    Thus,  a 100% agribusiness with a fertility of 50 and an educational level
    of 10 has an efficiency factor is 2/3;  one  civilian  can  harvest  0.033
    units of food per time unit beyond the food normally produced in that sec-
    tor.  This extra amount is enough to support 33-three other  people  while
    one military can harvest 0.0066, enough to feed 13 other people.

                                Concept : Food

    The  amount  of food cultivated by 10 civilians in 10 time units in a 100%
    agribusiness are:

                  |  EDUCATION LEVEL  |
                  |  0  |  10  |  100 |
            ------+-----+------+------+
            F  10 | 0.5 | 0.67 | 0.92 |
            E  ---+-----+------+------+
            R  50 | 2.5 | 3.33 | 4.58 |
            T  ---+-----+------+------+
            . 100 | 5.0 | 6.67 | 9.17 |
            ------+-----+------+------+

    SPECIAL NOTE: Residents of a sanctuary need no food to  survive;  thus  no
    one ever starves in a sanctuary.

                                Concept : Food

    On a ship the following applies:

      The  amount  of  food that can be produced on a fishing boat in one time
      unit is:

         civil / 100. * fertil / 100.

      The amount of food that can be produced on any other ship  in  one  time
      unit is:

         0

      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  units
      of  food  in  growing to adulthood.  However, 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 popula-
      tion has eaten), only three babies will be born and  one  unit  of  food
      will be left.
