Food is the basis for Population growth. A unit of food represents enough production/import to feed 10,000 people or 1 Population unit. Rural Pops produce food while Urban and Upper Class Pops consume it.
Food Production Edit
At a Glance:
- Rural Pops produce 1 Food plus the Farming Efficiency of the province
- Local Food is pooled at the regional level
- Rural Production of Food trade goods sells Food to the Continental Market, generating wealth
Rural Pops produce food at a base rate of 1 per pop, then the Farming Efficiency of the province is added to give the amount excess. For example, total food for a province with 1 rural pop and a FE of 45% would be:
Total Food = 1 + 0.45 = 1.45The Farming Efficiency of a region is increased through wealth investment that represents procurement of better tools at an early level all the way to large scale irrigation and advanced techniques. A portion of Rural, and to a lesser extent Urban, wealth is invested into improving FE rather than the state, meaning the best way to increase FE is by increasing the amount of wealth available at a local level. Besides a generally healthy economy, a healthy rural production and an influx of loot are two main ways rural wealth can be improved, an thus FE.
The Scottish Highlands will have a much lower base FE than the Nile River Valley, so every 1 Scottish Rural Pop will produce less excess food than their Nile counterparts.
Consumption and Distribution Edit
At a Glance:
- Each Pop consumes 1 Food
- The more Food available, the faster populations grow
- Local Food production pooled at Regional level
Food is first consumed by Rural Pops with the excess then going to feed urban centers. In game this is modeled by pooling the food production of all provinces in a region and subtracting out the food consumed by Rural Pops. Then the remainder is left for Urban Pops located in the region's cities. It is allocated based on Urban Gravity, or how strongly the city pulls food compared to its competitors.
With the exception of famines, there will usually be a surplus of food in a region. The amount of excess food as a percentage of total food [???] will be multiplied into the growth rate for all populations. What this means is if there is a lot of extra food compared to how much was consumed, populations will grow faster. So if there is 90% excess (very high), and the growth rate is 1.01, then the real rate will be .909 per year. However, if the region is mature and uses nearly all the excess food, a 20% excess margin would mean a growth rate of .202 per year. The result of this is that regions will not out strip their food supplies, and if damaged, Urban Pops will rebound comparatively quickly.
Because the Scottish Rural Pops only produce 1.05 units of food compared to 1.4 in the Nile , 200,000 Scottish farmers (20 pops) could only support 10,000 city dwellers (1 pop), while 200,000 Nile farmers support 80,000. The excess food in the Nile will be split between major cities such as Cairo, with its [insert correct CoP, CoT and Capital modifiers] giving it an Urban Gravity of [ ### ] and Alexandria [ Same ]
Continental Market Edit
Lastly, through Rural Production, Nobles can set a portion of the food produced in a province to be exported to the Continental Market for use by bustling cities of more than 50,000 (5 Urban Pops). The Wharf District building chain increases the amount of food accessible to a city
Every 1 Rural Production from a Farm Estate exports 1 Food from the local pool to the Continental Market. This means there is less food in the local pool, stifling growth in the long term, but taxable rural wealth is accruing, helping to both finance the state, province and local estates. However, it is not always a simple short term long term balance, for example, the extra local wealth could help jumpstart the local economy in a particularly poor province, improving FE and infrastructure and resulting in a net gain in food over the long term. This could also be achieved through ample plunder returning home, but it is important to realize each situation distorts the factors differently.
