Though forests burn, trees retake farmland globally as agroforestry advances

What are the "obvious limitations"? There are many problems with today's industrialized agriculture, but I wouldn't call the limitations obvious. The article says it doesn't work well in Africa for instance, and I believe it, but isn't it just because we don't have the proper GMOs/fertilizers/pesticides for this kind of soil due to a lack of interest? Is there some "obvious limitation" that makes it impossible.
I am not criticizing agroforestry. It is not like I want pesticides, artificial fertilizers and lifeless fields. But they cite 1920 as the starting year for the beginning of modern agriculture. During that time, the world population went from 2 to 7 billion. If we want do bring back ancient techniques, we have to do it in that context.
I often see the forest treated as an example of an efficient for of agriculture, and sure, forests are really dense with life. However, they are like closed systems, everything that is produced by the forest is used by the forest. Now, what we want is a patch of land from which we can pull as much as possible in order to feed our cities. There may be trees, but it won't be like a natural forest.
To make things clear again, I don't view agroforestry as a bad thing. If it allows good yields on previously unexploited land and does it so while preserving biodiversity, what's not to love. I am just skeptical when considered as a substitute for modern industrial agriculture.
No, they are not. It depends on the type of forest of course, but in general forests produces excess. We get oxygen out of them. Wood. Meat. Mushrooms. Berries. Herbs .. and recreation.
Also forests grow with the right conditions and they can even create the right conditions to grow, if not bulldozed down, or dried up, or set on fire.
But I agree very much with the point, that it is a very annoying idea, to suddenly be able to feed all the people of the earth with ancient methods, that were not at all able to feed so much people.
(my bet is on highly automated intensive greenhouses, btw.)
Sure thing. I just debated the "closed system" point. Forests are mostly a cycle in themself (called ecosystem), but not enclosed.
Note that both of these are political problems at the core. The first will be solved (or not) as people decide living in a city is better leaving more land for the rest to get rich from. Education is a major factor here, and things have improved a lot in many countries. However political problems threaten to take this away.
Political problems are hard. I don't know how to get stable governments and rules so that farmers can trust some investment in better farming is worth making. Nobody else does either, but you will see lots of people proposing something.
It's not revolutions. If you as an ordinary not politically connected person are doing well, one of the government's henchmen will just take your property off you, and you (or your surviving family members) have no recourse.
It's easy to see how this dis-incentivizes investment in improvements.
Secure property tenure is probably the key problem to crack.
Basically pollution, resource destruction, and expense; from the OP:
> But today, the downsides of that kind of farming are becoming all too painful. Excess nitrogen fertilizer runs down watersheds to create vast dead zones in the Gulf of Mexico and elsewhere around the world. The rich soils of the U.S. Midwest or Ukraine, grown over thousands of years by billions of grazing animals, are almost gone, damaged by relentless plowing, blown away by the wind or washed away by storms.
> Everywhere, farmland is becoming increasingly acidic, demanding additional liming. Vast monoculture plantations act like an open bar to pests and diseases, forcing farmers to spend more and more on pesticides. Aquifers are being sucked dry, raising the cost of irrigation as new wells must be dug ever deeper. Industrial farming is engaged in a vicious circle of ever more inputs at ever greater expense to try to keep up with the challenges it creates.
> And often, it fails. About a third of the planet’s farmland has already been abandoned because of soil degradation.
How much of our agricultural bounty is sent as food aid, and serves to create only more hungry mouths?
Disabling all food aid, and requiring (/forcing) recipient populations to develop self-sufficiency, is a necessary step to fundamentally improving our agricultural systems. We can assist by providing education and family planning to Women in poverty-stricken countries.

> How much of our agricultural bounty is sent as food aid, and serves to create only more hungry mouths?
Also, I've read that such aid basically kneecaps the local economies. A large fraction of the local population is employed in food or clothing production, and the aid ends up just undercutting them and increasing unemployment (and even more dependence on aid).
One also can't just hand-wave over the negative externalities of modern farming. Pesticides, soil-carbon loss, and the energy requirements are completely unsustainable.
It is true that there's an enormous difference between a 'food forest' and a natural one. A lot of the research suggests that to adequately address climate change, we can't simply convert farmland to food-forests and call it a day. We actually need to return a significant portion of land back into natural forests.
There are problems but to deny the merits is delusional and dooms failure any insane strategy where a small shepard and veteran slinger believes himself the strongest and tries to wrestle Goliath instead of just slinging a rock at his head.
Japan had a government policy of only reforesting with two types of trees for economic purposes, in some cases replacing natural forest, and as a result there's a lack of biodiversity and Japan now has allergy seasons that are estimated to cost $2B a year: https://ensia.com/features/japan-reforestation-deforestation...
To add insult to injury, the economic rationale for planting lots of fast-growing wood never really panned out, because it turned out with even Japanese oversupply of timber that it was cheaper to import it from SEA.
Sustainable forestry would only take out some of the trees, leave the stumps and replant. The forest would still look like a forest but only a little sparser for a while. there are studies proving this leads to greater yields.
Already a lot of fields in Europe are not active due too over production of crops. We should probably mix trees and farmland and open up some of those closed fields. Trees will take some capacity of the land but that can be replaced by opening up closed areas.
“ Roots take in water, and nutrients, from the soil. Without help from fungus for better uptake of nutrients, trees would be small or would die. Most trees have a favorite species of fungus that they associate with for this purpose.” Source: https://simple.m.wikipedia.org/wiki/Tree
Now say that you mix crops and trees then you probably can find trees and crops which mix well together. The crop will side load get a boost of nutrients from the trees fungus.
Furthermore, since the amount of photosynthesis is dependent on the amount of sunlight, it is likely that your staple crops would be the ones that required a lot of sunlight, since those are usually calorie dense.
I just don't see any benefits beyond companion planting with a groundcover crop like cucurbits, which would be far easier to mechanize.
We have similar processes going on in industrial farming in North America and Europe where we have been slowly depleting and giving up on what used to be healthy farm land. E.g. large parts of Spain are very arid but that wasn't always the case. Likewise parts of Italy and France are drying out because of intensive farming. It's less of an issue in more Northern parts of Europe but even there, decades of monoculture have created problems.
The message here is simple: it's a revertible process and it's a relatively quick process that doesn't necessarily involve much more than a bit of pruning, nurturing, and being mindful of the way nature works locally. It seems most of the complexity and cost is related to creating the right incentives, removing bureaucratic obstacles, and educating people a bit. Scaling this up seems like it's worthwhile. In most places where this could work, people have very little left to lose and a lot to gain.
If Africans in the middle of nowhere, far away from modern infrastructure can pull this off in some of the harshest environments in the world with little or no means, others can do that too. E.g. the Mid west and Texas come to mind in the US. Or the plains of Spain, which used to have forest and now looks more like the Sahara.
For example, a farm in the UK may follow the Wakelyns approach: https://vimeo.com/256082580 Alleys oriented to maximise the sun for the crops they're intending to grow. With tree species selected for various reasons, e.g. their size and if they fix nitrogen.
In the Sahara, maybe you want shade. Many growers intentionally use shade nets to reduce evaporation and heat stress. It depends on your context and your aims.
I expect there's some degree of trade off. Lose a portion of productivity of your annual staple crops, in exchange for the benefits of mixing perennial crops with annuals. Depending on your situation you may be able to control much of this when designing the farm.
Crop diversity is a pretty key part of that, as is appropriate fungal and insect management.
Avoiding chemical pesticides is hard by the way -- in my current (tiny) garden, it's been the only way I was able to keep the aphids and mites from absolutely destroying my jalapeños. Ladybugs would be preferable, but are incredibly hard to come by here.
Home and/or municipal composting adds another level to this, and it'd be great to get to the point where a large percentage of packaging was directly compostable. That'll be tricky -- you don't want the packaging to break down until after the lifetime of the food inside it -- but likely doable as manufacturing advances.
I think we should change our expectations for food shopping/packaging and shelf life. If we move away from an expectation for year-round availability, and crazy long shelf life, we can do away with all of the shipping, warehousing and packaging that is derived from that demand. In regards to carbon, packaging is non-trivial, but I think it is second to the shipping involved.
So, here's a question: do you think you could convince people to give up smartphones?
Because I think it'd be about the same level of difficulty.
People really, really, really don't like to surrender convenience or comfort.
I realize you aren't advocating this -- you have great intentions -- but crazy long shelf lives keep a lot of people from starving.
I'm interested in the micro-farming idea primarily because (a) I like the idea of adding more redundancy into the food supply; (b) because fresh food tastes amazing; and (c) because it's an interesting problem to solve. But I'd rather see that we roll the clock forward, and develop better technology to enable both year-round availability and healthy ultra-long-life foods, while at the same time deploying indefinitely sustainable agricultural practices.
In practice however, you may see carbon taxes change the way people consume international goods as prices on food would most certainly go up. Bananas in Australia are a good example, occasionally they fluctuate in price and you can see consumers aren't willing to wear the higer costs. Maybe it wouldn't be a disaster if Australians could only eat local fruits for example, I think it would ruffle the status quo but pretty quickly people would adapt.
I feel like a carbon tax on shipping would level the playing field toward local microfarming as well, and I would love to see agrofarming become a part of big country landscapes. Both the US and Australia are characterized by a vast majority of land being a patchwork quilt of cleared fields. I would love to see that change in my life time.
I think I wouldn't have this opinion if shipping were carbon nuetral mind you.
The abstract seems to validate both the parent comment's claims and your experience:
> The studies show that the integration of trees and crops can increase resource use efficiency, but careful management and a system design tailored to local climatic and soil conditions are required if competition and consequent reduction in crop yields are to be avoided.
I love to support - but ultimately I am volunteering my money for their profit margin.
That being said, recently I have been feeling that all my efforts are for not, sure I might be making the world a better place in my own small way but for what purpose?
Every day I watch as the people around me exploit the environment to enrich themselves while I get left behind. So lately the little voice in my head has been whispering "You own this land, why not clear cut the trees, make a couple hundred grand off the raw logs, buy a tractor to disc the land that's left and grow out a few years of annual grains then sell off the spent pesticide laiden land and live the rest of my life in a condo with a big bank account."
I know this sound selfish but why should I just scrape by working my fingers to the bone, whilst the rest of my community sells out? I feel like someone shit in the pool and I'm going to be the last one to get out.
I guess my point is every inch of soil I build and every tree I protect is like money in the bank, I can cash in at any time I want. The truth is every day I get more tired and feel the pull to cash it all in for my own selfish gains.
Making money by destroying your own property is in general not doable.
It might not make sense but it is what it is, I guess.
As such, nature areas - especially when they have a protected status - will be worth less than areas where the trees can be harvested commercially.
A piece of land will have value proportional to how much (say) timber it can produce in the future. OP talked about turning it into "spent pesticide laden land", which to me sounds like nothing will ever grow there again.
And commercially, dead land like that has no value.
Truth is I was having a weak moment when I wrote that comment, I dont think there is a homesteader that hasn't share my thoughts at some point.
Sorry for the whining rant!! Chin up!
Just trying to provide a middle pathway that compromises between "cash it all out" and "leave it pristine & don't touch anything" :)
First, it is not against you personally but I have seen this remarks and suggestions too much that I need to scratch an the itch. When the idea of the necessity to market oneself and go get a patreon had raised so much? I get it, it is a way to be the patron of some person doing art, good, whatever in the world as an alternative to grant, funding and old-school benefactors. But why do we have to create a content in response to that, act like we have to create a community around oneself or the project to get the money?
It make me really awkward every time I see a reach like that. I perceive it like a call to create a cult-ish of personality and to enforce the exposure of all in the world through a tiny window made by the different communities you are being part of. And for those people be upfront, they have to stay always the same to keep being the reflection of every member of their communities or it backlashes against them. I always feel awkward that the first response to funding finish to be : put yourself out there and market yourself to get a community and money to create your project. Do not forget to create daily vlog/insta/youtube/whatever so everyone can see that your are here making what we give you money for.
Sorry for the rant.
I basically try to plant something for everything I take out, and to replace non-natives with natives. A coffee table from the Norway maple that a storm took down, and an eastern black cherry growing next to its rotting stump. Feels good.
Are you planning on making water skis? I normally just cut a few each year for my runner beans, I have heard that the larger trees mill into good floor boards in barns as they are easy on animals feet. I do know they don't make very good firewood as they produce insane amounts of ash.
I had a number of exceedingly huge poplars taken down 5 years ago as they were threatening the house. I had some of it milled and had a dining room table made, and have a bunch for my own hobbying as well. It's a great wood, really should be used more simply because it's very renewable; cut it down and it comes right back Obi-Wan.
Yes, it's soft but it's easy to work, is lightweight but has good tensile strength (great for skis!), and has a beautiful tone -- mine had sat in the field for a year and had developed some beautiful spalting, rainbow toned. Mostly that goes away after it is sanded and so on and sits inside but there's still some there.
So my goal now is to see how long it will take for poplars to grow with the minimum diameter to make ski cores. I might not even need to hire a mill, might be sufficient to just get them to a minimum diameter, peel and dry them, and then plane them -- they grow pretty straight. Even not growing wide, ski cores are usually a composite of laminated strips, I could probably glue a number of narrower ones together just fine.
> That being said, recently I have been feeling that all my efforts are for not, sure I might be making the world a better place in my own small way but for what purpose?
There's two things there to unpack.
First, making our part of the world better is really all we can do.
I'm a big fan of "be the change you want to see in the world". Be a role model. Show others why doing this is a good thing.
If that proves unworkable, then, well, as the saying goes, "there's your problem."
Educate others, but when they push back -- listen. Don't shout over them, or insult them. Understand why they push back, and either learn to address their concerns, or adapt your world-view to encompass them.
The second part -- what's the purpose? -- is something only you can answer.
I love nature. Especially trees. Living in Tokyo, you really start to miss trees and green spaces.
The Tokyo mindset seems to be, "oh, look, there's a bit of dirt, we could pour concrete on that."
That's why I want some land. I'm not trying to change the world, or score points from other people. My motivation is purely intrinsic -- I want that for me. And because I believe it makes the world nicer, but since I live in the world, that's also something for me.
Probably also for my future kids. I want them to be at home anywhere, whether it's rural nowhere, or a dense urban core. Far too many people have only one perspective, and it limits them.
Figure out why things matter to you. If it's because you want something from other people, validation or what-have-you -- and I am not saying that is the case -- then you're just going to be disappointed.
> I guess my point is every inch of soil I build and every tree I protect is like money in the bank, I can cash in at any time I want. The truth is every day I get more tired and feel the pull to cash it all in for my own selfish gains.
Well, which would make you happier? More money in the bank, or having your own personal forest?
Interesting fact, it was a Japanese farmers book that started me off on my path towards owning this property.
I too was living in a big city and felt the pull back to nature, then I read a tiny book called "One Straw Revolution" and I was sold on the simpler life.
I guess it's kind of a grass is greener situation as I have recently been missing living in the city with all the services offered there but when I was there I wanted to live in the country.
I think I will take the day off tomorrow (after my chores) and go for a couple hour walk through the bush, maybe it will refresh my attitude if I take a break from the grind.
Emotions matter. You're feeling that way for a reason, and should probably dig a bit into that.
Maybe it might help to sit down and list out what it is you miss, and why?
That'd give you a good starting point to see if you can't fix some of those things.
You can also book an AirBnB in a city and go spend some time there, which might help you gain a better sense of perspective.
Good book, I have read it. Check out Krishna McKenzie of Solitude Farm, Auroville, India. An Englishman who studied at a J. Krishnamurti school in England, read that One Straw book by Masanobu Fukuoka while still in school, was so influenced by it that he went to Auroville and started a farm there (with a few others), based on Fukuoka's natural farming and permaculture's principles - all this, 25 years ago, and he is still going strong there. He has many videos on his Youtube channel about his farm work, edible weeds of the area, their farm cafe where they sell/serve healthy organic food made from their farm products, food and medicinal values of the 140-odd species they grow there, making permaculture circle gardens, hedgerows, mulch trenches, growing with high biodiversity, etc.
The incredible values of edible weeds. https://youtu.be/Ne39EwOffOU

We’ll be in an area that gets a fair amount of precip (typical afternoon t storms) but could go a week or two with rain.
I've modified my driveway to pull water off the road and into my system.
I also use grey water; I have a sink in the garden where I wash produce and it drains into a mini-swale to feed strawberries, onions, and a couple plum trees.
I'm also considering rigging up an outside shower for the same reason to water another area.
My goal is to eventually get some IBC totes to hold roof runoff. I'm also considering purchasing a small pump since I have access to a fast flowing 15 foot deep stream.
One other thing to note, you'd be surprised just how resilient trees, srubs, and plants are to water stresses, if you use enough mulch. The soil life will thank you as well.
Additionally, once you establish a system it tends toward self-renewal, planting perennial trees, shrubs, vines, and ground cover resolves water issues in most contexts. The biomass (both alive and dead) will accumulate and help with water retention.
We do have a ton of trees and shrubs and bushes and I'm going to be making some gardens with native wildflowers that should be able to resist the local weather machinations but I'd like to find some drought tolerant vegetables.
It works by using a slow dripping wick to make a connection with the capillary water deep below for the roots to follow. [2]

We are an animal species literally growing on fossil fuels.
Two potential solutions are a)
Create the ammonia from green hydrogen i.e. made from water with renewavle electricity
b)
Theres a process that turns natural gas (ideally from food waste) into hydrogen plus graphite do the carbon becomes a usable resource ratger than being vented as CO2.
Of course, manure and compost have their own set of CO2 (and methane) emission problems. At least it's carbon neutral I guess.
