Local sustainability

Some time ago, shortly after I started this blog, I created a whole list of topics that I wanted to do posts on. Today, I realized that I still had a few that were not done, so I am finishing all the posts I had sitting in my backlog. Then I can move on with some other ideas that I have.

One of the ideas I wanted to write about is what I call local sustainability. The idea of local sustainability is that a locality, whether a city or a town or a county or what ever distinction it might have, should be able to provide for its own needs, and not depend on outside resources for the necessities of life. It has been a long time since this sort of thing actually was common, but I don't know that it is necessarily a bad idea. Lets evaluate why.

First, lets look at what our current situation is. We mostly live in large cities. Our cities mostly provide services, with a few very large concentrations of finished goods manufacturing. Our cities certainly, with very few exceptions, do not provide raw materials. In some degree, they do process raw materials into finished goods (or some form of intermediate goods). People in cities mostly consume, and produce little. Our raw materials and even most of our finished goods come from elsewhere. Lately, most of it seems to be coming from China, but there have been other sources at other times. Our food doesn't come from where people live either. We have an estimated 3 days of food on shelves in most American and Industrialized cities. Our energy is generally not locally produced either. Some power plants are thousands of miles from the cities where the energy produced is used. Much of our oil and finished products now comes from overseas. Even most of the oil and finished products that are produced domestically still has to be shipped thousands of miles.

There are benefits to our current situation which unless maintained, would not make a switch to local sustainability an acceptable choice to most people. In our current system, we have very low cost, high end or high tech goods that are available from a large variety of sources. We can get almost anything we want nearly instantaneously if we have the means to pay for them, and even for those with smaller means, the amount of goods in their economic reach far exceed anything available in past eras.

In order to make a switch to local sustainability one of two things has to happen. The most likely and least desirable of these is some form of economic collapse affecting infrastructure, and lowering the availability of goods to crisis levels. The variety of goods would shrink 100 fold, and the costs would out pace all but the wealthiest of people for anything but the most basic goods. Famine and death would be rampant and most of us would die or wish we were dead.

The other option would be a new set of technology, business, and regulatory developments which when functioning jointly, would enable localities, or at least city sized regions to become able to produce 95% of what is consumed in those cities, using either directly produced or recycled raw materials or at the very least, with raw materials being primarily the goods being shipped into the cities from multi-regional or semi local supply sources. These developments would have to be able to produce almost anything on demand. The one thing that would be truly global would be the designs and manufacturing blueprints use by flexible micro manufacturing facilities which would need to be able to produce anything within a very large range of materials. For instance, there would need to be a electronics manufacturing facility that could use designs and blueprints from any developer to produce whatever the local consumer wanted, and produce it on demand.

In order for this to work, there would also have to be certain green space requirements primarily concerned with organic food production. The food production would have to have a much greater level of automation in its production, but instead of the mammoth machines currently being used by agricorps, these would require smart, possibly robotic, cultivators which would be able to produce higher quality and healthier crops in relatively small spaces. They would also need to be able to cultivate a wide variety of crops simultaneously, and with a minimum of pesticides and other chemicals. Larger green zones would also be needed for the raising of animal crops, with other more novel approaches facilitating the raising of the animals. Energy would have to be a local product, but with photovoltaic, wind power, and other systems becoming more efficient and less expensive all the time, this is become a real possibility today.

Of course, this kind of development would take a huge effort, but it would also have huge payoffs for just about everyone, from rich to poor, government, business, and just the lay consumer. The question is, who is willing to devote time, effort, and resources to the development of such a system.
