Wasn't it Khrushchev who wanted to plant maize in Kazakhstan, and it turned out to be the worst crop imaginable, and the USSR went from being an exporter to an importer of food?Quote:

As a child, I had thought that the desertification of North Africa was thanks to the romans, that hunted and catched all the lions and predators in the area. As a result, herbivores proliferated without any natural control, and went on a rampage eating all the green in the area. The resulting lack of vegetation only eased the wind erosion...
I don't know if that theory stands, though, but it's a nice story nonetheless. :grin:
In Australia we've experienced some changes in soil fertility in the 200+ years since Europeans invaded. The trends seem to be deforestation, climate fluctuation and salination.
We have an educated scientific culture and we have measured how tree-cutting leads directly to poorer soils, but the logging industry is so powerful they literally buy governments (eg Tasmanian State Governments) and push on regardless. I believe the West Australian state government had a policy to clear a million acres a year to put the "wheat belt" under cultivation, a truly disasterous (although well meant) policy.
Part of the problem is industrial scale intervention: wherever we irrigate on a big scale we get major salination problems (although the exact mechanism is debated, the result is clear). We also have water disputes where states up-river have built rice and cotton industries (great money spinners) in semi-arid regions (d'oh): states down stream are literally drying off the map (eg South Australia).
I imagine the middle east has experienced all these trends in spades.
I doubt that Middle Eastern desertification is due to a single factor (Genghis' goat policy or whatever), but in some ways they have been victims of their own success. The "Fertile Crescent" has supported millions of people from the dawn of agriculture. For much of its history it was the most civilised region on the planet, with sophisticated urban cultures shedding light on us all. I think they used up their environmental bikkies, albeit slower than my country is doing on our rather fragile soils.
Irrigation is a big deal in Mesopotamia. There's a theory civilization formed under the impetus of hydraulic engneering, the need to organise enough bodies to dig enough channels to grow crops in a rainless plain. So long as the people were in charge of their own destinies they looked after their water.
I guess the fragmentation of Islam under the Turkic and Mongol invasions didn't help keep up the infrastructure. I understand there are some quite succesful cultivation programs (eg in Israel and the Emirates) where there's expertise, capital and central authority to run modern industrial farms. Whether these projects are sustainable over centuries is another matter: maybe its not really about water, and the soils are spent .
Of course if I was to put up the "one guy" that might have made a difference (and frankly thats what I really want to do, even though I know its wrong), I'll blame Alexander. The Achaemenid love of gardens and qanats would surely have led to a greener future than the imperialist Macos with their pyromaniac drinking parties.
Also I want to blame Cromwell or Longstreet, somehow they're involved.
Bactria was fabled for its "1000 gilded cities". A map of the excavations of the area I have seen, tells of cities and Hellenistic colonies built almost exclusively on river sides and when possible on more than one... It was VERY productive. If you like lemons and oranges, it is here they came from. Also, it is noted that a lot of Greeks went over and settled there, as the climate was almost exactly as it was in Greece.Quote:

Iraq, due to the grand engineering works, it truely was one of the most productive regions of the ancient world, so far as agriculture was concerned. All that came to an end when the Mongolians razed and burned Baghdad in the 12th century. They destroyed those engineering works utterly and ever since then, the most productive farmland of the world is underutilised.
Eastern Spain, I don't know. Others could speak about it. What we know of the Greek colonies in the region, Hemeroskopeion (that was its name in 272 BCE, NOT Arse), Kallipolis (Barcelona) and Emprorion (Ampurias) is that they were presumed to have a small but fruitful food cultivation zone around them -so was speculated, according to other colonies we know of.

Again, seems counter-intuitive. Can you back up your claims with sources? Specifically that the mongols targeted hydraulic engineers. While you're at it, prove to me that the Mongol-hydraulic engineer-ocaust specifically led to desertification and/or the more-or-less complete elimination of this knowledge for (?) years.Quote:

We also invented a proto 3-meals a day concept (some Arab living in spain). we wrote beautiful poetry (even before Islam), transfered ancient knowlege to europeans from main sources, made androids, wrote sociology books (Ibn Khaldun), and put Alexander the great to shame....so I'd shut my mouth up if I were you..Quote:

@lobf: the Mongols do represent a religious movement/upheaval (sort of). they were known to play religions against one another, and often used their conquests to justify that the judeo-christian/ Muslim god was either non-existant, or that the losers deserved "divine wrath" (toppling the Khalifah, wiping out those eastern europeans, etc). Even Tamerlane, a muslim, attacked other muslims, saying they deserved divine retribution by himself. If you find a good book on the sack of baghdad, you'll see a gruesome example being made of the khalifah...not a pretty thing.
they also killed everybody save artists (for buildings), scribes, and siege engineers. they did in fact kill all other technicians (the ones for agriculture included). It was Mongol Policy to do that, so as to terrify all neighbors into submission, which backfired at the battle of 3ain jallut in 1260-something.
second, here's is my message to you Barry soteiro : *throws the rigid digit salute*. http://en.wikipedia.org/wiki/Flipping_the_bird
Yes this would be Khrushchev's idea of using the Aral Sea to irrigate the surrounding regions of the Soviet Union so that they could produce corn. If you take a look at modern pictures of the Aral Sea, 1, 2, 3, you can tell exactly how that turned out.Quote:

From what I have read so far, I do not believe there will be any examples from the EB world but many of you may still find it an interesting read.

I'm not a fanboy. Its just that that is still a lot more land, at a similar rate-I'm well aware of the exaustion of of the two empires, especially Persia.Quote:

Bad language, off topic, and intractable arguments. Time to close.
