Since food production is also geared to supply and demand, production volume and consumption always adapt to each other.
Another basis for answering the question is the profit from the production of food.
If no profit can be made, it is not produced.
If the profit is too low, i.e. the farmer or large-scale farm cannot feed itself, the amount of food produced will be small or completely absent, as the producers will then have to come up with other productions for their own survival.
It becomes more complicated when the place of production and consumption are far apart.
Then there are high transport costs, which some consumers cannot bear, and if so, only in predominantly equivalent economic zones (Spain – Sweden, D. – Brazil, etc.).
It becomes even more difficult when the economic zones involved are unequal, i.e. rational production of high quality, and, on the other hand, customers from areas with little effective economic output, which then also have little economic resources there (money, machines, etc.) available.
As a rule, producers of rational economic performance have their own market for customers, consisting of equivalent productions and qualities, so they always have the chance to sell their products.
However, if their decrease falls for whatever reason, it is sometimes worthwhile to sell surpluses below price, see europ.dairy products in Africa, etc.
This also sometimes creates a market for political and economic elites, e.g. in Africa, which can lead to a lasting but low demand there.
To answer the question, there are still climate effects that lead to economic areas shifting, disappearing or, for example, becoming smaller.
If production follows the needs, it is pointless to assume that others can eat more if you are less yourself.
In real terms, the regional marketing area, which can be reached through demand, information and means of transport, decides how much is produced.
The!apparent! meaningful global view, if in A more, then in B less, is thus an illusion, since any kind of production is based on:
1.any kind of product must be paid for with the cost factors at the production site.
2.only at the production site can the demand be estimated in order to be able to produce a product rationally and in line with the market.
3.In principle, the efficiency gaps between the human parties prevent the product produced from being sold universally at any place, which is why any kind of calculation of global food distribution is absolutely unreal.
4.It is indeed possible to finance state-supported overproduction, whatever the reasons for it, just as dairy products have been/are supported in the EU. But if there is not enough monie to come in from less efficient states, then this money is always missing in the end, which is why such social productions cannot last in the end.
