How far can a community push self-sufficiency before the complexity becomes another dependency?

I've been working on a long-term pre-land project called Melondra, and one of the questions I keep coming back to is where practical self-sufficiency stops helping and starts creating a different kind of fragility.

The aim isn't to disconnect completely from the outside world.

It's more to ask how much of the infrastructure needed for a comfortable modern life could sensibly be brought closer to the people using it.

For example:

producing a meaningful proportion of food locally;
preserving and storing seasonal surpluses;
collecting, storing and reusing water;
generating and storing energy;
recovering useful heat rather than simply throwing it away;
composting and nutrient recovery;
workshops and local repair;
shared tools and equipment;
some local manufacturing/fabrication;
keeping useful stocks of parts and materials;
designing systems so that they degrade gracefully when something fails.

Where I'm particularly interested is the interaction between all those systems.

A greenhouse isn't only a greenhouse if waste heat from another process can warm it.

Food waste isn't necessarily waste if it becomes feedstock for another system.

Stored rainwater, treated wastewater and potable water don't necessarily need to be treated as one interchangeable resource.

A workshop can be much more valuable if it also allows the community to maintain the machinery that its food, water and energy systems depend upon.

But there's an obvious danger.

Every additional pump, controller, sensor, treatment process or automated system creates something else that needs maintaining.

A supposedly "self-sufficient" settlement that can't function because one proprietary controller has failed isn't very self-sufficient at all.

So the direction we're currently exploring is:

use technology and automation where they genuinely reduce labour or resource use, but keep essential systems understandable, repairable and capable of useful degraded/manual operation.

That balance is one of the things I'd particularly value the experience of people here on.

For those who have actually built homesteads, permaculture systems, off-grid infrastructure or intentional communities:

which systems have genuinely made you more independent over time, and which ones turned out to create more maintenance and dependency than they were worth?

And at community scale, are there things that you think become dramatically more practical with 50–100 households than they ever could be for one homestead?

The wider project is here for context: https://melondra.org

It's still pre-land and very much a developing design rather than something I'm presenting as a finished solution.

I haven't absorbed and contemplated this whole post thoroughly yet, but my initial thought is that in some situations you can create fragility by having complicated systems that become reliant on a single individual - if that individual becomes unavailable for any reason, something critical may fail and there will be no back-up plan.

If you look even several hundred years back - before the industrial revolution - parents started teaching their children those complicated systems by the age of 5. They were essentially training their replacement.

Yes, keeping things simple and repairable is important. Our old washing machine had mechanical switches. It died (it was 30+ years old). The replacement has all electronic switches which not only can't be repaired, they likely aren't standard enough to be easily replaced even 5 years from now. My neighbor's son recently bought a really old Ford car - (like Model T era. ) Why? Because between him and his dad, they can fix it.

Consider basing the essential infrastructure of the community on technology from around 1890. That allows gravity-fed water, wells and hand pumps, wood and masonry construction, passive heating/cooling, root cellars, canning and fermentation, animal and human power, belt-driven machinery, blacksmithing, woodworking, mechanical workshops, sewing, bicycles, railways, windmills, simple electrical generation, and sophisticated agriculture.

Base it on systems that people can understand, maintain, repair, and reproduce locally.

Then layer modern technology on top wherever it helps. Solar panels, electronics, automation, power tools, computers, modern materials—all wonderful. But when possible, let their failure result in inconvenience or more human labor rather than failure of the essential system.

If an irrigation controller fails, open a valve by hand. If a pump fails, perhaps gravity still moves some water. If refrigeration fails, some of the food supply still stores by other means.

Plan for graceful degradation: modern technology makes the community easier to operate, rather than making the community possible to operate.

I would list five:
-Bison shallow well pump, paid $500 12 years ago, now it's close to $2000, but would buy again in a heartbeat; never let me down except one year when due to drought the water level dropped below my 6 m pipe and then I thought the pump broke and purchased set of new seals, but it was completely fine
-direct solar fridge: works with one panel, does not work at night but improves quality of life by 1000%
-irrigation system, no electronics, just hoses, valves and emitters: without it, it was impossible to establish any trees, as watering 300 plants by hand in 40 C and scorching sun will kill and why to have a homestead if it feels like penal colony?
-tractor: cultivated hostile land, moved tens of tons of building materials, trees cut for firewood, lifted logs to the mill, perimeter discing for fire break, pulling stuck vehicles in muddy winter; it has to be older model with proven technology
-direct solar small device charging, with no charge controllers, batteries, inverters, breakers, etc: I directly charge my laptops, phones and Makita batteries (which I use for one power tool and two lights); before I was using cheaply made small generators that were breaking after 3 months beyond repair

In general I do not feel like I ever purchased any tool that I would not be happy with, as I do a lot of research and try to buy quality things, made of thick metal with minimal electronics. Because of that I'm able to repair them - a process that I hate, as I do not like repairing things, but somehow I always succeed.
I have a lot of tools that I use once or twice per year - like rock coring drill or large stone saw, but when I use them, I'm always glad I have them as the rental would quickly surpass the tools' initial purchase price.

I don't have much practical experience with this yet, but I have thought about it.

Like the post above me said, if you want TRUE self sufficiency you probably have to go pre 1900 tech like the Amish (partly, I know it's complicated).

Most of us probably aren't willing to give up cars and electricity and electronics and the internet. How would we post on this forum?!

So there will always be a certain percentage you have to import from the outside world, and you have to pay with cash so you need to somehow make money either from a job or selling your products/produce/services to the outside world.

How big is that percentage? I think it depends a bit on your personality, comfort level, and how you measure it, but I think for me it's likely around 30%? I probably won't be giving up my truck, my phone, my laptop, or my internet access.

But in terms of food, I think getting to 98% or even 100% is much easier. Buildings, it depends on the materials and techniques you use. I'm not skilled (yet?) in natural building, and so I'm importing screws and nails and power tools and plywood. But the labor can mostly be internalized. The further you move towards natural building methods, the closer to independence you can get here. Still, windows will probably always be outside your wheelhouse, and will you blacksmith all your own nails?

Hello Gabe!

Welcome to permies!

I think a lot of your questions will be answered through doing.  

As you build the systems, you will see how they work together.

What region are you in?  I would go to other intentional communities and see what they have built and what is working well.

Wheaton Labs in Montana, built and run by Paul Wheaton, is an excellent example of  technology, innovation and simple living.  
https://wheaton-labs.com/

I would encourage you to spent a few days or a week there to get to know how it feels to live in a place like you want to build.   I believe you will come home with tons of great ideas for you new project.  


If you cannot travel to Montana, invest in a personal consultation with Paul.  He has personal experience with many communities and their founders.

I really like the underlying principle here.

I probably wouldn't set 1890 as a literal technology ceiling for the essential layer, but the idea of asking “what is the simplest version of this capability that can still function locally?” feels extremely useful.

Then modern technology can sit above that and reduce labour, improve efficiency, optimise things and make life much more comfortable — without becoming the single thing that makes the underlying system possible.

Your irrigation example is exactly the sort of behaviour I've been trying to describe: if the controller fails, watering becomes less convenient rather than impossible.

I think that gives me a much clearer test for future systems:

**when the clever layer disappears, what useful capability is still left underneath?**

That probably applies to food storage, water, heating, transport, communications and quite a lot else.

This is exactly the kind of real-world list I was hoping people would contribute.

What strikes me is that several of your biggest quality-of-life improvements aren't necessarily the most technologically complicated ones.

The irrigation system is a great example. Even without electronics, removing the need to hand-water hundreds of plants in extreme heat transforms what is practical.

And the direct-solar examples are making me think harder about how many unnecessary conversion/storage/control stages we sometimes add simply because that's the conventional architecture.

If something can sensibly use the resource directly, every intermediate box is another cost, efficiency loss and potential failure point.

The old tractor point makes sense in the same way too — sophisticated enough to remove enormous amounts of physical labour, but still understandable and repairable.

That feels like a much better test than simply asking whether something is “high tech” or “low tech”: **how much useful capability and labour saving does it give you for the complexity it introduces?**

As a bit of a Luddite, and using an outhouse in my early years, I am not convinced that modern technology necessarily reduces labor, improves efficiency, or makes life more comfortable.

Joseph,

Please elaborate what you consider to be modern as I'm also used to extremely Spartan lifestyle.
