The Hanging Gardens of Babylon
12 Dec 2014
The Hanging Gardens Of Babylon was why the city was built . A huge , fortified , vertical farm . The whole city was the garden . And that was the wonder of it . They actually were in advance of anything existing today .
The closest image I can find on the web . A far cry from today .
1.A quick calculation :
Size of Babylon : 900 hectares . http://en.wikipedia.org/wiki/Babylon
This is 3000 m x 3000 m.
2.The walls at every 10 m and 20 m high .
This gives surface area of walls of
A=(3000/10)^2 x2x2x20 sq m
= 540 000 000 sqm
=133 437 acres .
3.One person requires
The minimum amount of arable land required to sustainably support one person is 0.07 of a hectare. This assumes a largely vegetarian diet, no farmland degradation or water shortages, virtually no post- harvest waste, and farmers who know precisely when and how to plant, fertilize, irrigate, etc.
Thus , Babylon could support 133437/0.17 = 784 923 persons from it’s vertical farms alone .
4.Babylon’s population :
Babylon about 200 000 .
This leaves a huge surplus , used in projection of power throughout the region .
5.Babylon exported food . Amazing !
The rural areas did not feed the city !
But it had to keep control of the waterworks . Hence the continual large military presence .
Empire in self-defense .
They did it better .
No wonder the cities never recovered .
The walls and irrigation works were deliberately destroyed , and with it the foundation of the power of Babylon and Niniveh
See how the Persians retained some remnants of the city-wide air-conditioning and intensive agriculture .
8.How on earth did this develop ?
After the collapse of the Bronze age and really bad droughts in the region and volkewanderung reivers
Former agricultural societies depopulated , and was forced to grow food inside fortified compounds .
This naturally evolved into vertical farms and some very good farmers .
The Hanging Gardens of Babylon .
The whole city was one big ,air-conditioned hanging garden , with aerosols of water cascading from above .
Eat your hearts out , greens .
9. Something similar is happening today in the Greening of Inner Cities . A sure sign of collapse .
10. The Tower of Babel.
An extravagance of learning , enabling large trees in terraces .
The trees came first , then , because it was elitist , the academics followed .
Scholars from everywhere , all talking different languages .
The original inspiration for Plato’s Academe of trees .
11. Vertical farming in the middle East was deliberately destroyed by local powers for short term gain , as was the quanat system later by the Mongols .
The result is the desert of today .
Typical of the Tragedy of The Commons .
Grow up or die .
