Ages ago, I had Vol. 2, _The Metal Lathe_ which was one of the 7 vol. "Gingery Books", a series on _Build Your Own Metal Working Shop from Scrap_ (Vol. 1 was _The Charcoal Foundry_) which used as its central conceit the fact that a lathe is the one tool in a machine shop suited to easily replicating itself (insert old machinist joke about how you can make anything with a shaper, except money).
Always regretted giving my original away, the typewritten text and hand-drawings had a certain charm which the updated single leatherbound hardcover lack.
The Gingery Book Store is shutting down this year, and not reprinting any books, so one wonders what will replace it:
Another effort along these lines was the "Multimachine" which attempted to create a metal-working equivalent to the woodworking shop's ShopSmith using an engine block, taking advantage of the fact that they are readily and inexpensively available from junked vehicles. I believe it was on the "Opensource Ecology" site linked elsethread.
Perhaps Chris Borge's series of machine tools made with 3D printed shells filled with concrete and arrayed with hardware store components?
That said, as various machinists have joked, I am still "shaper curious", and have been sketching up a hand-operated shaper --- debating on saving for a set of castings, making my own, or going the hardware store route....

Victor Papanek's Design for the Real World [0] is a foundational text in the area of Appropriate Technology (cited here by others).
Essential reading alongside the Illich (also linked by others), Pye's Nature and Art of Workmanship [1], and Winner's "Do Artifacts Have Politics?" [2] for those interested in.... Let's call it an ecology OF technology?
And also the Papanek was probably the book that felt most like a forbidden text in undergraduate architecture school...
I like the idea behind this. I feel like far too often, the solutions we build for poor communities involve specific materials that can't be manufactured locally, so it just creates more dependence rather than self-sufficiency.
It's one thing to build and ship 1000 bicycles to a poor village, but it's another to teach a village how to make bicycles with random spare pipes and materials they can find anywhere. That way if something breaks, they have the skillset to fix it.
If you go to villages in developing nations, you'll see these kinds of innovative solutions all over - things that don't seem like they should work but they just do after lots of trial and error.

I strongly agree that it's incomparably more important to teach a man/village how to fish/build a bike than to give them one. Unfortunately most people who focus on "helping" are grossly incompetent and have largely misaligned incentives (and oversight).
As for local innovation, it think it very much depends on where. I've visited and lived in many communities in developing nations in Latin America and there's a distinct dearth of not just innovative solutions, but even just basic and seemingly obvious ones. Upon seeing and feeling this 7 years ago, I decided to dedicate my life to it. I'm hopeful that in the coming year I'll finally be ready to share what I've been working on to facilitate it in a more scalable way...

When I went to South Africa last, we went through a few slums.
It was comical to see the celebrity "assistance" in the form of e.g., a music production studio + school set up by skrillex, neighboring areas where people lived in shipping crates with stolen electricity jumpered directly from main, and with water tapped off city lines and bucketted in.
They dont need djs, they need plubmbers, carpenters, and electricians first! Fires and water loss were endemic. Almost everyone lived off government assistance, stole / smuggled resources, and blocked traffic/protested when the illegal resource taps were shut down or a government job didn't manifest. The people who made money where they lived usually washed cars or sold trinkets to tourists or brewed bucket beer.

Music, much like sport, is seen by many working class people as a way to make some money, so not completely senseless. Art to a lesser extent.
Carpenters/joiners are a good half-way house, as they can provide both practical assistance to the community as well as selling collectibles/souvenirs or whatever.
The problem is the minute some of these people pick up skills or money, they leave the slums behind. The plumbers and electricians may make better money rigging up office blocks than from fitting out the slums.

It goes deeper than that if you ask me. It's rarely about "helping" in a lot of cases in the first place, and there's no incompetence at play either.
Just look at food aid to Africa. You know, the campaigns with banners of emaciated African children holding empty food bowls. These aren't primarily about helping African children, but about diverting European (or American) oversupply towards Africa to stabilize prices in the domestic markets - and they all but wiped out African food industry. Simbabwe was known as the "corn chamber of Africa" but lost that in a matter of decades as the cheap food from Europe was cheaper than they could produce. Or clothing donations, these ended up as "mitumba" in Africa, and wrecked local supply chains so hard that, by the time the Chinese came around, there was nothing left to fight.

In my fairly extensive experience, non-profit organizations are not just full of and run by grossly incompetent people, but deeply arrogant and/or deluded ones as well. I have NEVER found an organization that has a genuine desire to seek truth, efficacy etc. They often go with whatever their first (inevitably insufficient) idea was, and not only reject all criticism but respond with indignity, etc...
There's no meaningful/competent oversight. It's all just about feels and optics. And thus no real progress has or will be made.
Anyway, yes, I agree that competent and genuine people (who are extremely rare) ought to try to make a meaningful impact in the world. But there's generally more money in something else.

To some extent, one doesn't even see the competent non-profits. They don't market aggressively, they don't scale up rapidly, they just stick to their niche and quietly hammer away at it for decades on end (often on things that have no feasible exit, like schools that will need to be externally funded forever)
fragmede 19 hours ago [-]
That seems like a simple money regulations issue. If the school has a $100 million endowment, but doesn't spend into it, the school would exist forever. If we say 10% returns a year, that's $10 million to spend on students in the form of teachers and classrooms and housing and books and everything. Unfortunately, that only teaches N students per year. But it would last ~forever. If, however, you get greedy with wanting to teach more than N students per year, then you get into the treadmill of needing external funding forever, but on the face of it, I don't accept that external funding is required forever.
swiftcoder 19 hours ago [-]
A 100 million endowment is effectively "forever funding" from the perspective of a school that takes in maybe 200k/year of donations. You don't get 100 million endowments without the scale and marketing, unfortunately

Buying and shipping X amount of Y to <country> is easy to calculate the cost. And it's a fixed one time cost. Perfect for PR OP, and humanitarian operation with limited budget and/or available work hours.
Teaching takes the most valuable resources of all: Time. And it's harder to predict how long (and therefor how much $$) it will take before having sustainable results. And it requires on-premise staff and usually to setup some building for the staff, for the teaching grounds, etc.
Tl;DR teaching can easily be 10X the time and money budget of a quick 'send stuff' operation. This is why these are usually big operation handled by big non-profit.
OAF lends materials and teachers to farmers to make the more productive, by the end of the program they got productive enough to pay back the loan and OAF can lend the same money to someone else.
It's super capillary, with many boots on grounds and quality problems.
Embedded into this there's a good feedback channel: farmers who don't think are getting a good service stop paying back the loan. This allows OAF to go and audit what's failing there.
I think this extends to wealthy communities too. Basically every item in my home more complex than a spoon is beyond my capacity to manufacture or repair. A resource that teaches me how to build useful things without relying on a complex supply chain or prohibitively expensive tools would be pretty darn liberating.

Well, fundamentally, there are two different types of furniture:

What would be nice is setting up as much manufacturing as possible in Africa for making bikes designed for Africa.
Bike maintenance isn't a skill issue. It's an issue of specialised tools and hard to get spares. Talk to your own Grand parents. If they weren't rich they'd have had to fix their own bike, and they wouldn't have had Google helping them.

What would be different about a bike designed for Africa than one designed for anywhere else? What parts that require specialized tools should be redesigned to use standard tools?
The buffalo bike is one that was specifically made for developing nations and the project prioritizes local assembly and repair, while the bike is designed to sacrifice weight and aerodynamics, instead offering heavier-duty parts like thicker rims, puncture-proof tires, high-capacity racks, etc. This bike has two chains to reduce the likelihood of a critical failure and an internal coaster brake hub which is more robust to the elements.
Your average low-cost bike isn't intended to be used in environments with rough terrain and high contaminant concentrations without regular maintenance, and especially older bikes with things like cup and cone bearings which are more susceptible to dirt getting in, thinner tires which puncture more easily, and nonstandard bits and pieces like derailleur hangers which predate the UDH standard.

Buffalo bicycles cost around $150 at least. That's frankly way too expensive to be a good bike for developing countries no matter how well suited it is for rough terrain.

Off the top of my head. Steel frame, can be repaired / modified with any old welder. Designed so it can be taken apart with the minimum of generic tools. Standard bearings, brake blocks etc (probably brake blocks that you can shove some piece of old tyre in).
Front forks and the crank require special tools to remove. I assume the free wheel assembly would be the same. I don't know if it would be possible to modify these to be serviceable with basic tools, the point is an African could probably work out how to fix a bike, the issue would be affording tools and spares, and availability of those tools and spares.

Some parts of Africa are similar to elsewhere, but obvious things would be parts that can deal with either extreme dryness or humidity (both problems in different parts of the continent), good suspension (for areas with bad roads), bright colours (for visibility on shared roads), integration of bike locks and easy self-repair (for people in more remote areas).
And Illich (where the term "tool" is quite broad, including anything from a knife to a highway system):
Tools foster conviviality to the extent to which they can be easily used, by anybody, as often or as seldom as desired, for the accomplishment of a purpose chosen by the user. The use of such tools by one person does not restrain another from using them equally. They do not require previous certification of the user. Their existence does not impose any obligation to use them. They allow the user to express his meaning in action.
Industrial tools deny this possibility to those who use them and they allow their designers to determine the meaning and expectations of others. Most tools today cannot be used in a convivial fashion.

There's not actually all that many useful things that can be made in poor, underresourced countries and villages.

As other comments have implied, but not explicitly said, they do their own engineering already with what they have.
Since materials can be scarce and inconsistent, much of it is improvised. That in no way diminishes their efforts, results, or knowledge. If anything, that's way more impressive. Lots of engineers in the first world will throw a tantrum if they can't have things exactly their way and probably still make something that doesn't work as well. Entire businesses have shit their pants and gone bankrupt the moment a part is discontinued.
Trying to do better than the people who live there is not only arrogant, but it's own variation of Chesterton's Fence.
EDIT: I can't help myself and have to post an engineerguy video. It's too important of a topic to not drive this point home crystal clear by someone who is far more respected than me.
"Building a Cathedral without Science or Mathematics: The Engineering Method Explained"
As someone who has spent some time in sub-saharan Africa, I can tell you that there is lots that can be done if just seeing the possibilities.
Not everyone everywhere are "engineering oriented", and having people with the skills and eye for practical solutions based on available materials, can help tons, and also open up people's imagination for what can be done.
In fact, this goes for northern Europe too, just that more people can manage without home-built solutions and can "buy away the problem" here.
Also, people where immensely thankful e.g. when my quite clever and crafty father managed to repair a water tank tower that'd been broken for months and years, by sourcing some local material, coming up with a repair design, and having local welders create it, etc etc.
sublinear 21 hours ago [-]
I've never been to sub-saharan Africa, but I did grow up broke enough to be on the receiving end of people with good intentions.
I'm not saying you're necessarily wrong, but the realities of a situation guided by those who more deeply understand it can very quickly prune the possibilities that an engineer sees. Many engineers would just get frustrated and give up. Many leaders would become impatient with those engineers.
I think to get people's heads out of the clouds and produce real results requires a very special kind of engineer. That is most likely going to be someone local, not an outsider. One can definitely help on the education side of things for the locals, but I'm not convinced that's where the real problems are. It's more likely political and economic. Not even the best engineers in the world are going to solve that.

Which is a misunderstanding of the premise that locals know best.
No one thinks that going to someone and offering them ideas is bad. The thing people actually object to is imperialism, and they object to it because it's common. All over the place you see not just governments making rules from an ivory tower, but even well-meaning non-profits providing grants or resources with the requirement that things be done in a particular way with no regard for local conditions.
If you're trying to help someone then you shouldn't need to coerce them. Nobody was ever objecting to the cases where you don't.

Actually, plenty of people - including the person I was replying to - explicitly argue that locals know best and you're being imperialist by even suggesting that outsiders might have anything useful to contribute other than money.
And, yes, you do need to "coerce"/convince/persuade/retrain people across many dimensions - people are generally extremely resistant to change, and instead stick with whatever theyre already doing. Not all interventions are just immediately self-evidently beneficial. Eg. "Hey stop destroying your topsoil by every means imaginable - removing and burning all waste from the harvest, not planting in contours to prevent erosion" and much much more. That takes time to prove out and even then requires a leap of faith.
I do strongly agree, though, that "well meaning" non-profits are quite often completely clueless and, arguably, destructive. Often through the very gifts they give, which often don't even work, or at least go counter towards the necessary goal of developing self-sufficiency.

My wife came across the Jean Pain compost water heater recently, and I've been really intrigued by the idea. I haven't found a great compact design though, and most of the information I see online treats it more like a fun project than something that could be iterated on and refined. Would love to find somewhere to trade ideas on this and potentially replace some or all of gas water heater.
You might want to look at biogas digester design - I met farmers near Hanover who were running big biogas digesters, and using the excess heat to heat their homes and pools all winter…

That looks rather primitive. I wonder whether the difference between low-tech and high-tech isn’t simply an aesthetic one. If the designs were adapted so that they no longer looked as they’d been designed by an anarcho-primitivist, would we still regard them as low-tech at all?

It is not about aesthetics but functionality achieved with cheap avaiable material. That looks seldom beautiful.
I love this project. I often lament how narrowly focused on tech/software open source tends to be. It is the most powerful example of human altruism that I can think of but it tends not to address a lot of peoples basic needs.

See also Hugh Piggott's detailed recipe books for building wind turbines, e.g. https://scoraigwind.co.uk/all-of-the-books-by-hugh-how-to-ge... . They were originally printed paper books because they pre-date the internet, and have been popular, e.g. in Scottish island communities, for a long time. I see now they are available as paid eBooks, which seems reasonable to me because the price is very low and a lot of effort has gone into making them, but I wonder if that will be a problem nowadays with people expecting everything on the internet to be free.
Also lots and lots of manufacturing and repair work is like kept secret from the common people or at least that is the general vibe. So I'm happy for this initiative.

Yes, an air conditioner can be made as follows.
1. Identify a locally viable deciduous tree species.
2. Plant this species on the afternoon aspect of the sun in your location. So for northern hemisphere plant to the southwest. For southern hemisphere plant to the northwest.
3. Enjoy shade in summer and sun in winter, plus cleaner air.
Another option depending upon your architecture is to take advantage of forced air within a roof cavity. Buy a large diameter fan with an electronic control, install at apex, and set it to operate when the temperature exceeds a certain point. This will result in a house wide temperature drop with no need to expend $$$ setup plus dollars per hour per room on air conditioning.
Another option is simply shading. One of the simplest and most traditional approaches here is the drop awning. A drop awning consists of a retractable material expanse which can render a building surface in shade and thus promote rapid air movement and cooling in the hottest periods.
Two final options include internal forced air: passive variant (open all the windows and doors) or active variant (ceiling fan, solar works) and insulation or thermal mass.

I would argue that, for anything with value, there is value in having a decent open source option for that thing. I think farm equipment is valuable, so I think it's great that someone is working on an open source option. You are right though, it is an enormously uphill battle. To get off the ground, there would likely need to be a well funded non profit involved. Would be cool to see Futo or similar tackle something like this

I think it makes more sense if it's not viewed under the aspect of trying to be maximally productive in its output. If you look at it over they years, they've also tried to do a share of public outreach / education (though I'm not sure how successful), and I think they also sustain themselves in terms of labor with burnt out tech people that are looking for a change of scenery.
So similar to a good zoo, that does both active conservation work, and at the same time public education (e.g. in the form of guided tours for school trips).

Always regretted giving my original away, the typewritten text and hand-drawings had a certain charm which the updated single leatherbound hardcover lack.
The Gingery Book Store is shutting down this year, and not reprinting any books, so one wonders what will replace it:

Another effort along these lines was the "Multimachine" which attempted to create a metal-working equivalent to the woodworking shop's ShopSmith using an engine block, taking advantage of the fact that they are readily and inexpensively available from junked vehicles. I believe it was on the "Opensource Ecology" site linked elsethread.
Perhaps Chris Borge's series of machine tools made with 3D printed shells filled with concrete and arrayed with hardware store components?
https://hackaday.com/2025/04/13/3d-printed-milling-machine-i...
That said, as various machinists have joked, I am still "shaper curious", and have been sketching up a hand-operated shaper --- debating on saving for a set of castings, making my own, or going the hardware store route....

It's one thing to build and ship 1000 bicycles to a poor village, but it's another to teach a village how to make bicycles with random spare pipes and materials they can find anywhere. That way if something breaks, they have the skillset to fix it.
If you go to villages in developing nations, you'll see these kinds of innovative solutions all over - things that don't seem like they should work but they just do after lots of trial and error.
As for local innovation, it think it very much depends on where. I've visited and lived in many communities in developing nations in Latin America and there's a distinct dearth of not just innovative solutions, but even just basic and seemingly obvious ones. Upon seeing and feeling this 7 years ago, I decided to dedicate my life to it. I'm hopeful that in the coming year I'll finally be ready to share what I've been working on to facilitate it in a more scalable way...
It was comical to see the celebrity "assistance" in the form of e.g., a music production studio + school set up by skrillex, neighboring areas where people lived in shipping crates with stolen electricity jumpered directly from main, and with water tapped off city lines and bucketted in.
They dont need djs, they need plubmbers, carpenters, and electricians first! Fires and water loss were endemic. Almost everyone lived off government assistance, stole / smuggled resources, and blocked traffic/protested when the illegal resource taps were shut down or a government job didn't manifest. The people who made money where they lived usually washed cars or sold trinkets to tourists or brewed bucket beer.
Carpenters/joiners are a good half-way house, as they can provide both practical assistance to the community as well as selling collectibles/souvenirs or whatever.
The problem is the minute some of these people pick up skills or money, they leave the slums behind. The plumbers and electricians may make better money rigging up office blocks than from fitting out the slums.

It goes deeper than that if you ask me. It's rarely about "helping" in a lot of cases in the first place, and there's no incompetence at play either.
Just look at food aid to Africa. You know, the campaigns with banners of emaciated African children holding empty food bowls. These aren't primarily about helping African children, but about diverting European (or American) oversupply towards Africa to stabilize prices in the domestic markets - and they all but wiped out African food industry. Simbabwe was known as the "corn chamber of Africa" but lost that in a matter of decades as the cheap food from Europe was cheaper than they could produce. Or clothing donations, these ended up as "mitumba" in Africa, and wrecked local supply chains so hard that, by the time the Chinese came around, there was nothing left to fight.
Zimbabwe's agricultural sector was wrecked by handing farms to Mugabe loyalists who didn't know what to do with them. His government didn't just go for whites, but also some of the black farm workers who would have known how to use them.
Likewise, the famine in Ethiopia was not helped by either Mengistu's Marxist government (who used Live Aid money for arms) or the previous set up under Emperor Haile Selassie which was based on clientism.
Because no one is willing to pay them for it and they have bills to pay.
He's teaching proper engineering with commodity parts and accessible technologies.
There's no meaningful/competent oversight. It's all just about feels and optics. And thus no real progress has or will be made.
Anyway, yes, I agree that competent and genuine people (who are extremely rare) ought to try to make a meaningful impact in the world. But there's generally more money in something else.
(one rare exception that comes to mind, though i haven't visited them, is The Ocean Cleanup project. They seem to be experimenting and succeeding towards the worthwhile goal of making effective engineering interventions for cleaning up waterways and oceans)

I'm sure there's plenty of incompetent nonprofits out there, but there's plenty of incompetent for-profits as well.
Setting aside cynicism is one thing but what answers are there for skepticism besides the very common moralizing personal attacks?
When I see a lot of nonprofit leadership improving their own lot much more reliably than the people “they serve”, I wonder if the handouts are just being politically diverted to the best and most politically valuable promoters.
If UBI is off the table, competition for gatekeeping resources becomes a dark market.

Is there no gatekeeping of pools of money?
Im not going to put effort into turning those other people in another country into a new cash crop for billionaires.
Years ago I remember reading an article about Russians making a living in the USSR. A man in a town wanted to mow his lawn but could not afford a mower (or maybe he could not easily obtain one?)

Buying and shipping X amount of Y to <country> is easy to calculate the cost. And it's a fixed one time cost. Perfect for PR OP, and humanitarian operation with limited budget and/or available work hours.
Teaching takes the most valuable resources of all: Time. And it's harder to predict how long (and therefor how much $$) it will take before having sustainable results. And it requires on-premise staff and usually to setup some building for the staff, for the teaching grounds, etc.
Tl;DR teaching can easily be 10X the time and money budget of a quick 'send stuff' operation. This is why these are usually big operation handled by big non-profit.
See for example https://oneacrefund.org/ [0] where they have a revolving loan fund.
OAF lends materials and teachers to farmers to make the more productive, by the end of the program they got productive enough to pay back the loan and OAF can lend the same money to someone else.
It's super capillary, with many boots on grounds and quality problems.
Embedded into this there's a good feedback channel: farmers who don't think are getting a good service stop paying back the loan. This allows OAF to go and audit what's failing there.

These tools might be useful in war, weird remote situations or maybe when no capital/investors are willing to inject capital in some remote poor african village. But I can't see why any government that can borrow money should do that.

Any changes to the status quo will have to contend with powerful questions because why build bonds with people you distrust? Why bother including insignificant nations in your decision process? Why not be top dog and trample everyone under your righteous boots? Why not exploit and generally harvest the shit out of everything in sight and retrieve resources for the absolute minimum you can get away with? These sound annoying and they are, but they are really tough questions and they demand a good answer. Just "be a good person" is not cutting it. We need systemic solutions.
In case you're wondering I have the answer: sadly I do not, but I am convinced a couple of you do so please enlighten me.
What do we care more about? The present? The current generation? Or future generations? Our children, grandchildren, great grandchildren? The perpetuation of human civilization? The perpetuation of human civilization with a set of values that that supports the growth and happiness of all?
That's the first question, right? Alignment. Sustainable alignment.
From there, it's all about sustaining those shared values, and minimizing risk. Build bonds: keep your friends close and your enemies closer. Or establish trust. It works out better in the long run; people don't usually Like to stab each other in the back Trampling starts cycles of revenge, and that's no fun for anyone involved either Exploitation prioritizes short term gain and screws you in the long run, more often than not.
Bike maintenance isn't a skill issue. It's an issue of specialised tools and hard to get spares. Talk to your own Grand parents. If they weren't rich they'd have had to fix their own bike, and they wouldn't have had Google helping them.
The buffalo bike is one that was specifically made for developing nations and the project prioritizes local assembly and repair, while the bike is designed to sacrifice weight and aerodynamics, instead offering heavier-duty parts like thicker rims, puncture-proof tires, high-capacity racks, etc. This bike has two chains to reduce the likelihood of a critical failure and an internal coaster brake hub which is more robust to the elements.
Your average low-cost bike isn't intended to be used in environments with rough terrain and high contaminant concentrations without regular maintenance, and especially older bikes with things like cup and cone bearings which are more susceptible to dirt getting in, thinner tires which puncture more easily, and nonstandard bits and pieces like derailleur hangers which predate the UDH standard.
The best bikes I saw were ones that a kid from a family could buy for maybe $20 in local currency and the repairability comes from the cheap cost - if something breaks down, you can find the replacement part from a spare bike that broke down months ago.
The site shows all the telltale signs of self-important, low-impact NGO.
I'm thinking that in the west we either have very cheap bikes that aren't really designed for long term use, and more expensive bikes tend to use fancier parts.
Off the top of my head. Steel frame, can be repaired / modified with any old welder. Designed so it can be taken apart with the minimum of generic tools. Standard bearings, brake blocks etc (probably brake blocks that you can shove some piece of old tyre in).
Front forks and the crank require special tools to remove. I assume the free wheel assembly would be the same. I don't know if it would be possible to modify these to be serviceable with basic tools, the point is an African could probably work out how to fix a bike, the issue would be affording tools and spares, and availability of those tools and spares.
So basically just your average cheap crappy Halfords Bike-Shaped Object type "bike"?
"very cheap bikes that aren't really designed for long term use"
You want cheap and reliable, not cheap with a load of doodads to make it seem expensive.
You still have the problem that the bits that you cannot just knock up out of old Morris Minor steering columns or AK47 barrels are the bits that break.
I know one person who has legitimately worn out a bike frame, in 40-something years of cycling, and it wasn't me. It was a guy who rode his bike about 50 miles *every single day* and rode from Edinburgh to Glasgow and back a couple of times a week. Eventually it started cracking around the welds.

Tools foster conviviality to the extent to which they can be easily used, by anybody, as often or as seldom as desired, for the accomplishment of a purpose chosen by the user. The use of such tools by one person does not restrain another from using them equally. They do not require previous certification of the user. Their existence does not impose any obligation to use them. They allow the user to express his meaning in action.
Industrial tools deny this possibility to those who use them and they allow their designers to determine the meaning and expectations of others. Most tools today cannot be used in a convivial fashion.
Also I think OLPC was a misguided project, as most of these things are. Its out of stem with maslows hierarchy of needs. Folks who are subsistence farmers with drought, smoke filled homes and stomach parasites don't need a laptop and academic education. They need practical and actionable tools and techniques to better meet their basic needs, a state from which they could better pursue academics etc
Since materials can be scarce and inconsistent, much of it is improvised. That in no way diminishes their efforts, results, or knowledge. If anything, that's way more impressive. Lots of engineers in the first world will throw a tantrum if they can't have things exactly their way and probably still make something that doesn't work as well. Entire businesses have shit their pants and gone bankrupt the moment a part is discontinued.
Trying to do better than the people who live there is not only arrogant, but it's own variation of Chesterton's Fence.
EDIT: I can't help myself and have to post an engineerguy video. It's too important of a topic to not drive this point home crystal clear by someone who is far more respected than me.
"Building a Cathedral without Science or Mathematics: The Engineering Method Explained"
https://youtube.com/watch?v=_ivqWN4L3zU
In India there is a word for this kind of thing Jugaad
https://en.wikipedia.org/wiki/Jugaad
Not everyone everywhere are "engineering oriented", and having people with the skills and eye for practical solutions based on available materials, can help tons, and also open up people's imagination for what can be done.
In fact, this goes for northern Europe too, just that more people can manage without home-built solutions and can "buy away the problem" here.
Also, people where immensely thankful e.g. when my quite clever and crafty father managed to repair a water tank tower that'd been broken for months and years, by sourcing some local material, coming up with a repair design, and having local welders create it, etc etc.
I'm not saying you're necessarily wrong, but the realities of a situation guided by those who more deeply understand it can very quickly prune the possibilities that an engineer sees. Many engineers would just get frustrated and give up. Many leaders would become impatient with those engineers.
I think to get people's heads out of the clouds and produce real results requires a very special kind of engineer. That is most likely going to be someone local, not an outsider. One can definitely help on the education side of things for the locals, but I'm not convinced that's where the real problems are. It's more likely political and economic. Not even the best engineers in the world are going to solve that.
As I elaborated on in another comment, it is commonplace to find that people who have little to no education and resources are missing countless opportunities to implement simple improvements to almost everything.
This mindset of "locals know best" is, frankly, toxic. (just think about the locals wherever you live to see how incompetent they are as well)
What is needed is genuine collaboration and communication between people living in whatever situation and others who are fortunate to have more access to information, resources, education on critical thinking etc...
This is insane.
But local people at least have the benefit of knowing their own situations, which puts them ahead of some other rando who doesn't even have that and presumes to know better.
No one thinks that going to someone and offering them ideas is bad. The thing people actually object to is imperialism, and they object to it because it's common.

If you're trying to help someone then you shouldn't need to coerce them. Nobody was ever objecting to the cases where you don't.
And, yes, you do need to "coerce"/convince/persuade/retrain people across many dimensions - people are generally extremely resistant to change, and instead stick with whatever theyre already doing. Not all interventions are just immediately self-evidently beneficial. Eg. "Hey stop destroying your topsoil by every means imaginable - removing and burning all waste from the harvest, not planting in contours to prevent erosion" and much much more. That takes time to prove out and even then requires a leap of faith.
I do strongly agree, though, that "well meaning" non-profits are quite often completely clueless and, arguably, destructive. Often through the very gifts they give, which often don't even work, or at least go counter towards the necessary goal of developing self-sufficiency.
