Psst. Wrong thread 


How about we try to think it through from the distribution of the most basic renewable resource, solar energy?citydreams said:What's so complicated? It's a case of optimising the level of production to maximise the benefits to society.
Or, to put it another way:
If there is a scenario whereby the world can be sustainable then there must be an efficient allocation of those resources that minimizes the cost to each person.
Sure but here to move resources around takes energy. For example, the non-renewable energy cost of a tomato grown on my patio is negligable. A Kenyan mango from Sainsburys has a non-renewable energy cost of about 1,000 x (or maybe it's 10,000 x, can't remember) the food energy gain from eating it.citydreams said:I understand your reasoning. But what you describe above is a boundary constraint and can be overcome by allocating resources according to the overall need/cost distribution.
It was the search for the efficient allocation of resources in the use of electrical substations that gave birth to optomisation theory.

I don't see that. To me it looks like you create inefficiencies each time you move resources around.citydreams said:Which is why a planned pricing mechanism can derive the most efficient allocation of resources!![]()
The inefficiencies arise because it costs energy to move that stuff around, and when you move food and other biomass products around, you move soil nutrients with them. I keep talking about the eco-village model because that allows for the effective recycling of soil nutrients and encourages the effective prevention of soil erosion. Commercial agriculture effectively strip-mines the soil using large amounts of fossil energy to do so, then wastes more fossil energy transporting the results around. It only makes sense economically, not in sustainability terms. Furthermore we're running out of places to strip-mine. The last places left are rain forests in places like Brazil, Malaysia and Indonesia and those rain forests play an essential role in damping out the effects of climate change. So let's not cut them down eh?citydreams said:How can there be inefficiencies with a surplus?
I don't disagree that it is possible to transport goods within a sustainable scenario, I'm just arguing that you want to minimise it as a matter of principle.citydreams said:But what you describe is not necessarily true. It is possible to transport goods within a sustainable scenario.
This all misses the point that any community has to work together as a unit. And no community can be cordoned by any clear definition. Consequentially, any solution has to be globally orientated.
Bernie Gunther said:I don't understand the second paragraph.
How do you deal with it? Transport almost invariably involves using fossil fuel energy, rather than any kind that can be straightforwardly derived from solar energy. Significant evidence exists to show that the energy balance of biofuels is net negative, whatever the economics say. In addition, biofuels compete with food for the available land and we're very close to the limits of the Earth's capability to produce food already.citydreams said:I don't want to minimise transport. I want to maximise potential outputs. Minimizing the environmental cost of transport I can deal with.
Bernie Gunther said:we're very close to the limits of the Earth's capability to produce food already.
Bernie Gunther said:How do you deal with it?.
citydreams said:And we have 30 years to find a solution. I would suggest that a mathematical model has a better chance of allocating the resources needed to bring this about than would sitting on my patio growing tomatoes.
Within the 30 year time frame there is going to be huge migrations of peoples. I would say that transport is very much on the agenda.

any real economist would laugh in your face if you proposed creating a worldwide centrally planned economy
What does a planter full of toms achieve? Free food, carbon sinking, hundreds of thousands of food miles prevented and a sense of self-reliance and independence
poet said:What does your hypothetical mathematical model actually achieve? Naff all in the forseeable future.

citydreams said:I have no leanings towards Trotsky. I was merely pointing out that is was possible in communist Russia to be able to set the prices of two million goods using outdated methods of calculation. I could do it on my calculator in quicker time.
citydreams said:I think you'll find they were at war at the time and not able to import the grain they needed.
bugsy7 said:Right! Only everybody's backed away from them (even to the extent of the Frogs abandoning one midway through construction in the early 90s) because they can't get them to work properly.
Kalkar (the only fast breeder successfully constructed in Germany) didn't even manage to get on the net before it, too, was abandoned.
One of the main problems is the highly voaltile coolant used, but nobody to date has come up with a better solution (excuse the pun).

When you're feeding 2000 mouths and bankrolling an agricultural college, then we'll talk.
citydreams said:Where do you get that from?
Russia, at 12%, has one of the lowest % of agricultural land in Europe
The country is huge and so has low population density but to define it as arable is laughable.
