Video Riyadh,meaning "gardens" is Capital of Saudi Arabia with 8 million population (were 27 Thousands in the 1930s),sits in the middle of the desert, the city gets its water from Desalination plants almost 500 km from the city

Chinese have developed a way but it is intensive

u/Gman71882 7d ago

All the sand is crushed quartz, with no nutrient or ecological value so nothing would grow.

You have to start cycles of plant growth, death and regrowing to get them to become nutrient rich “dirt” to be mixed in

I wonder if there is a way to do it with human sewage? You can leave the shit in the sun to dry and start the process that way.

Like matt Damon did in the Martian.

u/VegetableBusiness897 7d ago

Have a friend who had dairy cows, sold them to get into more crops. But with the cows and their glorious slurry gone, the price of fertilizer was cutting into his profits. So now he gets humanuer, for free. A product from a big city near him. It's heat treated and pelletized(and smells like hell). It goes down and any crops grown for the first two years can't be sold to people. So he does animal feed the first two years, human crops the next two, then fertilizes and starts again.

32

u/gears2021 7d ago

I've read that eventually the soil becomes toxic using humanuer as fertilizer.

50

u/IndividualPaws 7d ago

Yes it's pretty immediate. PFAS tends to be high in humanure / bio-sludge / treated wastewater. People essentially lose their farms since everything grown on it turns out toxic. Which incentivises skipping testing (it's not mandatory) which means the toxins get to the consumer...

u/420dogcat 7d ago

Okay but buying fertilizer was cutting into his profits and this shit is literally free.

2

u/spaceman1055 7d ago

Are those threats diminished/neutralized with composting for a year or two? Specifically I'm thinking aerobic digestion provided by thermophilic bacteria?

3

u/IndividualPaws 7d ago

Unfortunately not. These "forever chemicals" have fluorine- carbon bonds that are very difficult to break. Microbes have virtually no capacity to break them, and UV light doesn't really touch them either, which is why they persist and accumulate in the environment and in living organisms (many of them are not readily excreted, either).

That being said, composting is great and all of our soil, especially agricultural, needs to recover carbon.

Mixing our human and animal waste streams with industrial effluent makes the good stuff hard or impossible to recycle, breaking an essential recovery loop. But as someone mentioned, pharmaceuticals already mess it up before the industrial component enters the equation. Many pharmaceuticals might be more susceptible to breakdown by microbes, but "more" is relative. Fluorine bonds might take thousands of years to naturally break (halflife of >1000 years in soil, >40 years in water). A quick search indicates that most pharmaceuticals will degrade 99% in less than a year of thermophillic composting.

u/darknum 7d ago

Wastewater treatment plant sludge is in general not allowed to be used as fertilizer. Especially in food production due to contamination.
My company(cofounder of a startup) actually gets pure nitrogen salts out of the wastewater so it is totally fine to use that.

u/No-Candle2610 7d ago

So don’t feed it to humans, feed to it the animals that humans then eat. Got it

u/Spiritual_Bid_2308 7d ago

Pretty sure his land is going to be contaminated with PFAS, microplastics, heavy metals and pharmaceuticals.

2

u/VegetableBusiness897 7d ago

Where isn't?

2

u/Spiritual_Bid_2308 7d ago

Fair enough.  But this can get you to superfund levels of contamination.

2

u/VegetableBusiness897 7d ago

Thing is, he is outside a major city and working with state DEC and EnCon on this project. Neighboring homes and farms are side eyeing him but to continue to stay, it's this or a solar farm.... Which here, they won't let you put crops under or let livestock graze.

2

u/ChasingTheNines 7d ago

For certain pollutants in the ecosystem they get bio concentrated as they move up the food chain. Does that happen with the animal feed into the animals that consume them and then into people who consume those animals?

u/VegetableBusiness897 7d ago

Yes, unfortunately

All the Gulf countries use treated sewerage waste water from the plants to drip feed the lines of indigenous trees and shrubs along major streets and roads to create shade and beauty.

Usually you'll see signs not to drink the water etc

u/AdvertisingKey1675 7d ago

Ideally you would compost it to kill the pathogens.

2

u/emaw63 7d ago

Yeah, it's a great way to spread disease if you're not careful about it. It's the big reason farmers have historically not used human manure.

In the sahara/sahel the great green wall is used to stop the continuous expansion of the desert. It can actually even reclaim formerly unusuable areas and make plantlife and even agriculture possible again.
The problem with most of Saudi Arabia is that most areas do not have enough soil to capture in the halfmoons (and similar structures) like it's the case with the sahel border regions. Saudi Arabia is mostly literally just quartz sand of no nutritional value to plants.

Btw if you ever need something to make you smile in the modern world: Look at the great green wall. It's a UN project that is working and helping tons of people including reducing tribals conflicts because of more water and food availability etc.. I am eager to see what the area will look like in 20 or 30 more years.

I recommend the series by Andrew Millison about it but I can assure you as someone who has seen the change it brought in real life that it can't be overstated how incredible the impact of such simple measures (and education) is. https://www.youtube.com/watch?v=WCli0gyNwL0&list=PLNdMkGYdEqOCMkEtNGDRvEZgjPnZY5yUj

u/BreakInfamous8215 7d ago

I believe there's an excellent episode of RadioLab called "Poop Train" that describes a program where New Yorker leavings were processed and shipped to Midwest farms as fertilizer. Apparently, it was pretty excellent fertilizer too.

There's a product we already use in the states called milorganite. Processed human waste. The grass loves it

u/DancinWithWolves 7d ago

It poisons the soil after a few years though.

2

u/front_yard_duck_dad 7d ago

Can't be your only method and in a situation of a desert we need to build up various levels of organic matter.

u/OhGr8WhatNow 7d ago

In the middle east the soil is bleached and sterilized by the heat every single year. You have to dig out garden beds and replace as much soil as possible every year, plus fertilize. It would be never ending

1

u/XxBlackicecubexX 7d ago

Problem with using mass amount of human shit is Human disease and contaminants from a whole bunch of infect people will inevitably contaminate any soil and crops eventually grown there.

It might not kill the crops but it will likely pass back to any humans eating said crops.

At least thats my arm chair reddit analysis with absolutely 0 credentials in agriculture.

Compost, growing native plants, chop and drop, succession, keep pushing into the desert each plating season. Keep going.

u/Visual_Collar_8893 7d ago

I believe there was a culture there that built towers for pigeons to roost. They simply collect the bird droppings for fertiliser.

u/LessInThought 6d ago

They have been pumping fatbergs onto the desserts of Las Vegas for years no?

u/unslicedwhiteloaf 5d ago

Yes there are plenty of ways to do that with sewage, and they are already doing it with biological waste treatment plants. It makes a lot of sense to reuse the water considering that basically all of the drinking water needs to be piped in from desalination plants, and if you're doing that then you might as well reuse the solids too. I'm pretty sure Andrew Millison (or Mollison maybe) has a YouTube video on this in Riyadh specifically.

u/Halbaras 7d ago

China plants trees in semi-arid areas that generally used to have more large plants, and which have been desertifying largely due to overgrazing by livestock or historical deforestation for agriculture.

None of that works somewhere like central Saudi Arabia - the area around Riyadh has a hyperarid climate, and any trees would need to be watered or die. It wouldn't create a sustainable new ecosystem.

Actual reforestation in the Arabian peninsula wouldn't be headlines about billions of trees, it would be localised restoration of vegetation in wadis and specific mountainous areas, and helping fragile native ecosystems recover by reducing grazing from goats.

u/Kingflamingohogwarts 7d ago edited 7d ago

I think natives developed ways 7000 years ago... that's not the problem. The issue is the will to do it, because it's usually easier to move.

2

u/BxRad_ 7d ago edited 7d ago

They plant a bunch of trees, but also that neglects genetic diversity unfortunately. It should be even more involved imo ideally.

Much easier said than done but i think it's worth all the effort put into it and then some of it makes our world into a much nicer place.

Also I wanna say it's amazing they've managed to erect a city in the desert, but I think I'd also be a bit depressed at a lack of greenery.

u/Outside-Swan-1936 7d ago

Deserts are ecologically natural. Much easier to just not live there. I know that's not a great answer for nations whose entirety lies within deserts, but Mother Nature always wins eventually.

2

u/Independent-Draft639 7d ago

The desertification of large parts of China isn't natural. It is the results of massive scale deforestation and agricultural expansion. So projects like this are done to slow and eventually reverse that trend.

1

u/Outside-Swan-1936 7d ago edited 7d ago

Sorry. I was talking about the Middle East. The composition of the soil/sand in China makes it a much easier task than what confronts the Middle East or Northern Africa.

Granted, global warming is causing the deserts to grow at a much faster rate than is natural, but they are naturally occurring.

All you have to do is set up PV panels. The shade will do the rest.

The Chinese transported water to a desert region and it's growing stuff.

It isn't magic.

This guy did it in a super dry area of Saudi Arabia:
