I've been binging a lot of videos on things like rewilding and other approaches that can be used to restore landscapes. The Chinese have successfully executed a number of large scale projects over the decades. They started this early. Where other countries talked about doing things, the Chinese went ahead and did those things.
One of their projects is allowing them to undertake infrastructure projects in the desert. They simply stick bales of straw into ditches to stop soil being blown away by wind. The straw traps soil, water, and breaks down over a few years allowing plants to take hold. It's a simple approach that works. Very pramatic, dig a ditch, stick in some straw. Done. Repeat.
Outside of China, the green wall in Africa is a very pragmatic approach that involves digging a lot of half moon shaped ditches to trap rain water. Simple and effective.
Other approaches involve using fences to stop sheep and other grazers from preventing anything vaguely green tinted shoots from being eaten and giving them a chance to actually turn into trees.
What I like about these approaches is that some relatively simple measures can have big effects. People spend a lot of time hand wringing over seemingly insurmountable problems. The Chinese are showing that in addition to the power to destroy landscapes, we also have the power to remake them. It works. They aren't tree huggers. Better landscapes also mean local economies benefit. Deserts don't feed people. Water retention means agriculture gets a second chance.
What I admire in the Chinese is the pragmatic can do attitude. Their motivations are of course self serving. They value having clean air in their cities, clean drinking water, and a landscape that can support agriculture and infrastructure. And in the end that's the best kind of motivation you can get. It's something worth copying. Whenever economy, science, and environment align, everybody wins.
A lot of areas in the rest of the world that are subject to desertification, pollution, etc. are fixable. And there's value in fixing them that needs more attention. I don't see this as a green/left topic. If you exist on this planet, why wouldn't you want something to be done to clean up the mess we've all created in the last centuries? Breaking out this topic from the usual left/right day to day politics is key. The rest is just work. The Chinese put the rest of us to shame with hard work.
Do you know why the mounds with half-moon shapes? Why is it more effective than simply digging a circular hole in the ground?
The idea is that rain flows downhill, you dig the half moon shape to capture the water on the end without a ditch and then it sinks into the ditch instead of flowing unobstructed to the river and taking all soil with it.
It's an ancient practice that was forgotten and rediscovered. The beauty of this approach is that it shows results within a few short years. Basically in Africa if there's water, nature shows up and consumes it. So you get lush growth and rapid soil restoration. Trees, vegetables, etc. on what was a heavily eroded flood plain before.
It's easy to explain, the locals get why it works. And they get a very fast response from nature and all the produce and riches that come with that. And all they need is shovels and some elbow grease.
Same effect for half the work. Look up the videos on youtube, it's manual labor on very hard ground.
Why is it manual? If I had a mission to plant millions of trees, I am going to invest in a ditch witch.
assuming you're not joking, construction equipment is incredibly expensive for countries to whom profiting from importing it is not a "sure thing", doubly so if their roads are not developed. This is why a 2000s hummer in central America still costs as much as a nice modern car.
A basic trencher is little more than a push lawnmower frame with a chain saw attached. Not enormous industrial equipment, but still a large boost to productivity vs a shovel.
I think the basic trencher would almost certainly still count as manual labor? Nobody is expecting that they are out there digging with bare hands.
> Nobody is expecting that they are out there digging with bare hands.
Most of these ditches are dug out by the locals with shovels. We're talking subsistence farmers here in areas where people are more or less trying to live off the land. Their hands and some primitive tools is all that's there.
I confess that is a little surprising to me. Such that I can agree it would be a worthwhile endeavor to get them better equipment.
I would still call people using bigger stuff to be doing manual labor. For the same reason that using a lawn mower is still a manual labor job.
>Such that I can agree it would be a worthwhile endeavor to get them better equipment.
I imagine they /want/ it, it would just be a massive issue because they do not have equal supply chains to more developed nations, and them having to pay to make up the difference makes the cost-to-benefit ratio not make sense
again this is in a country that may have little to no debt infrastructure, so no way to take out a proper loan to buy the equipment, and many hoops to import it. The fact that it's small isn't the matter, it's that it's specialized. A used/legacy backhoe or skid steer maybe, but even if you can afford it, there's no tractor supply co or home depot, you are likely handling lading the thing yourself
local labour is cheaper
Any YouTube playlist that you can share?
Just search for things like "green wall", "china straw landscape", etc.
A few good ones that I watched:
- Inside Africa's Food Forest Mega-Project https://www.youtube.com/watch?v=xbBdIG--b58
- China Buried Tons of Dead Plants Under the Desert Sand https://www.youtube.com/watch?v=Ev8DsPH_82Y
- Green Gold: Regreening the Desert | John D. Liu https://www.youtube.com/watch?v=E3nR3G9jboc
There are way more. One channel that I might call https://www.youtube.com/@MossyEarth. They basically use donations to take on projects to do smalls scale nature restoration. I am actually considering making a donation to them because I like what they do. There are more examples of such channels.
Not everything on this front is without controversy of course and I'm not blind to that. But I like the positive, constructive nature of these approaches. Just the simple notion that it's fixable with a bit of cleverness and lots of hard work. China is of course an autocracy that you can criticize for a lot of things. But they are doing a few things right as well. And it's worth calling that out and learning from them.
This video https://www.youtube.com/watch?v=3qwshdtijFY and his whole channel are a great binge for this topic.
No nonsense, an actual practitioner, and not very "YouTubey"
