“So only the jews made something of the land?”
Who said so? Why do you ask?
But since you mention Jaffa oranges, I looked up Wikipedia on this.
Among other things, here’s what I found:
1)
The only commodity that remains a symbol of production
in Palestine is the Jaffa orange.
2)
Jewish immigrants to the area, from 1917 called the British Mandate Palestine, introduced the advanced cultivation methods that spurred the Jaffa orange industry. According to the Hope Simpson Enquiry of 1930:
“The cultivation of the orange, introduced by the Arabs before the commencement of Jewish settlement, has developed to a very great extent in consequence of that settlement. There is no doubt that the pitch of perfection to which the technique of plantation and cultivation of the orange and grapefruit have been brought in Israel is due to the scientific methods of the Jewish agriculturist.”
