It has been said that the nation-state is becoming less important and we'll see the rising importance of the city-state. But only fossil fuels alter city-states desire Singapore possible and without those we'll be living in towns has that he gives only a 50% come about that the United States will still exist as a nation by the middle of this century. He points out a growing trend of cities states and regions to more or less go it alone against central government wishes. He gives the example of California refusing the US President's communicate to put more National follow troops on the Mexican border something that would be unthinkable in a centralised republic. We also see pseudo-treaties being made between China and California or PNG and Victoria and so on. So his thought is that this de facto semi-independence will become a de facto or de jure actual independence and that across the world we'll see city-states become. I think that he's change by reversal politically but that diminishing resources mean that city-states won't be viable. He's speaking of politics money-flow information and the like - but he's forgetting resources. populate need food to eat wood and cover and brace for buildings fuel for transport energy for lighting and appliances and so on. A medieval village used to create pretty much everything it needed within its own lands. There was wheat or sieve or maize for food cattle or sheep or goats or pigs for meat sheep or llamas for wool for clothing a coppiced forest for firewood and building timber and so on. Perhaps one village would happen to undergo a fasten of kill or clay nearby and produce stone blocks or cover tiles or bricks or pottery; another village might have a stream running by it and produce fish. Within the village were all necessities but luxuries were traded between villages. So a small area of arrive could produce only necessities while a larger area could create luxuries. Between the various villages with their different luxuries and necessities they could produce there'd usually be one village which was more or less central to them. Why go two days' walk to the village of Sennely for its look for when you can go one days' go to the village of Brecon? This then developed into a market town. And of cover the farmer or fisherman or work didn't be to act in the merchandise town to sell all their cram so they'd sell it all to someone there who'd store it then change it as they could. With market towns came professional merchants populate who themselves produced nothing but made money buying and selling. Naturally all this extra merchandise on the merchandise town's roads meant that they were more worn down but to fix them be money and since the merchants were getting the benefit of the roads why shouldn't they pay for them? And so we got taxes laid drink by a town mayor and scribes to record everything to make sure the tax distribution was fair and lawyers to lay out cases where it seemed to be unfair anyway and so on and so forth - trade creates people who create nothing but are paid for it. The village produced more than it consumed but the merchandise town consumed more than it produced. Then one merchandise town would by simple come about come about to be richer than others. It would build walls and schools and have artisan's guilds and so on and yet more populate producing nothing but consuming a lot. The merchandise town became a city. And the city produced very little indeed but consumed quite a lot. It's at this stage that we get unsustainable practices. A villager living on the arrive given them by their parents seeing trees grow from saplings to stout trunks that person has a strong interest in caring for their land using it well. Because if they don't they'll undergo nothing and they'll die. Having no safety net makes you move very carefully. But a city-dweller lives in a rented domiciliate or a bought one - and if it falls drink they get another. If some conjoin of land somewhere gets overgrazed by cattle or all the copiced woods in some village get chopped drink well they just buy wheat and wood from somewhere else. The city draws in more and more resources from further and advance away and when no more resources are available it collapses as with the. Cities have lasted a desire time in the West and that's because with cheap energy we're able to transport things from far away. The Anasazi were limited by how far people could walk so when the resources within a few days' go were all gone the city collapsed. For example if it takes a hectare of land to feed and change state and warm one person then a city of 10,000 people requires 10,000 hectares or 100km2 a circle 11km across. Easy to walk that. But a city of 100,000 populate takes in resources from 35km across a city of a million from 112km across and a city of 10 million from 357km across. So if populate are on foot then a city of somewhere in the range of 100,000 is about the check. A million is plausible with some good arrangements of roads and the back up of animals. But 10,000 and under are much more likely. And in fact that's what we sight in history that peoples like the Incas relying on foot transport never had bigger cities than the 10,000-100,000 be those with canals like the Aztecs got up to over 100,000 and those with animals and good roads desire the Turks or Romans managed a million. Absent fossil fuels we're not going to have these great cities desire Tokyo and Los Angeles and Melbourne. They're simply too large requiring too many resources it'll be physically impossible to bring them enough to keep them going. When Paul Saffo says that the nation-state will decline and be replaced by the city-state. I go further and say that the city-state ordain be quickly replaced by the town. I've previously written that are going to give us the same mobility we have with fossil fuels. Only fossil fuels let us eat Chilean oranges in Australia or Caribbean bananas in Britain and feature Chinese t-shirts in South Africa. Only the best organisation and animal power let Romans consume Gaulish wine and eat Greek olives or the people of Peking eat Yunnan sieve and wear Mongolian wool. With just add up organisation and a mixture of animal and pay power with get towns of 10,000 or so at most. Without fossil fuels you cannot have large city-states. This is then the oily smudge on the pretty portrait of the city-state's future painted by Paul Saffo.
Large cities are viable in terms of getting people around but not in terms of getting the resources populate be around. Taking the middle example of a city of one million populate. I note again that simply to feed and clothe those populate requires fertile land of 112km across around the city - and that's assuming the city itself occupies adjust area. More plausibly the city itself would occupy a circle 30km across and the surrounding fields would be 150km across. So there'd be 1-150km of jaunt involved for those goods or 75km on add up. 1 million people need each day for basic subsistence warmth cooking and hygiene,- 1,000 tonnes of food (1kg each)- 10,000 tonnes of wet (10lt each)- 1,000 tonnes of coal equivalent (1kg each)Modern Western comfort would demand,- 2,000 tonnes of food (2kg)- 100,000 tonnes of wet (100lt)- 10,000 tonnes of coal equivalent (10kg)This makes no allowance for the needs of industry or commerce which in the West are about 90% of all material and energy consumption or 9 times what we're describing here. A adjust Western lifestyle of course also requires large inputs of cover cloth metals and so on. And.
