Importing & Exporting Food

The important part of having food and shields in a central trade area is that, when you enter into diplomacy, you can trade food and shields in much the same way as you trade luxuries and strategic resources.

I like that :)
The central trading area could be some sort of Small Wonder too!
 
Something not mentioned here and something I forgot to mention in my own redundant thread:

Food trading should not be allowed to increase a city's size. If you wanted to increase the size of a city in the mountains, you would need to use workers (or my own suggested unit, migrants) to up the city's size - food trading should only be usable for maintaining a city's size.

That seems reasonable, but how then are new citizens produced?
 
Good question Teabeard. Cities would grow the same way they grow now - the city with the surplus food production would thus have to balance between exporting food to other cities or civs, and have enough left over to increase its pop for new workers, etc.

What I meant was that a city importing food should not be allowed to use that food to increase its own population. And obviously, the city exporting food will not grow as quickly - that is the trade-off for food trading, as is the shields you'll need to build workers/migrants for your cities in the hills.

Since your civ overall should be producing the same amount of food, with careful management you should be able to support the same population overall, and the population should grow at about the same rate.
 
I think food trade should be automated. This is how.

Players can assign a percentage of each city's food surplus to the national pool. This is controlled on a nationwide basis as a slider ("each city assigns X% of surplus food to the pool"). Pool assigned food is first reduced based on city corruption and efficiency of transport technology. Until you have rails and hermetically sealed transportable grain silos, transporting food just isn't going to be particularly efficient.

Next, surplus food is assigned to any cities that have a food shortage. If there is not enough to cover all the food shortages, it is assigned to cities according to culture. The higher culture cities get their shortage met before the lower culture cities.

If any food from the pool is left over after all cities have their shortages met, it is assigned to all cities proportionately according to the total culture in each city. Say you have 1000 total culture, 500 in your capital, and 30 surplus pool food, 15 of that pool will be sent to your capital. This reflects that the breadbasket plains 'cities' of the midwest don't grow, but the cultural centres on the coast are massive. It also prevents a serious MM problem.
 
Truth be known, I think that the whole model for population growth needs to be totally overhauled. Food should still have a role in determining population growth, but should be subsumed into other, more important factors. Happiness, terrain, wealth and access to manufactured goods and luxuries should all play a role in population growth-with food more a factor in whether you people are well fed or starving (which ties into happiness and, therefore, population growth ;)!)

Yours,
