And if that doesn't convince you, there are a number of accounts to the barren nature of the Land of Israel without the Jews.
The 7 Wonders of Jewish History
6) The Interdependency of the Jewish People and the Land of Israel

It has been prophesied in the Torah that the land of Israel was rich and fertile while the Jews were living there:
I have come down to rescue them from Egypts power. I will bring them out of that land, to a good, spacious land, to a land flowing with milk and honey
(Exodus 3:8)
Even up until the time of Josephus (i.e. approximately 1300 years later), it was still very prosperous and fertile.
For the whole area is excellent for crops or pasturage and rich in trees of every kind, so that by its fertility it invites even those least inclined to work on the land. In fact, every inch of it has been cultivated by the inhabitants and not a parcel goes to waste. It is thickly covered with towns, and thanks to the natural abundance of the soil, the many villages are so densely populated that the smallest of them has more than fifteen thousand inhabitants.
(Josephus, The Jewish Wars; Book III 3:2 Penguin edition, p. 192)
And when they were exiled, it would become barren and desolate:
So devastated will I leave the land that your enemies who live there will be astonished
Your land will remain desolate, and your cities in ruins.
(Leviticus 26:32-33)
During the two thousand years of Israels exile from its Land, numerous empires have conquered the Land and countless wars were fought for its possession. And yet, astonishingly, no conqueror ever succeeded in permanently settling the Land or causing the deserts to blossom.
Mark Twain, who visited Israel in 1867, describes the Land of Israel:
We traversed some miles of desolate country whose soil is rich enough but is given wholly to weeds - A silent, mournful expanse
A desolation is here that not even imagination can grace with the pomp of life and action . The further we went the hotter the sun got and the more rocky and bare, repulsive and dreary the landscape became.
(The Innocents Abroad Vol. II)
Others make similar observations:
Outside the walls of Jerusalem however we saw no living being, heard no living voice. We encountered that desolation and that deadly silence which we would have expected to find at the ruined gates of Pompey
A total eternal dread spell envelopes the city, the highways and the villages
the burial grounds of an entire people.
Alfons de Lamartine, Recollections of the East Volume I London (1845) pg. 238 (Hebrew-French)
Until today no people has succeeded in establishing national dominion in the land of Israel
No national unity or spirit of nationalism has acquired any hold there. The mixed multitude of itinerant tribes that managed to settle there did so on lease, as temporary residents. It seems that they await the return of the permanent residents of the land.
Professor Sir John William Dosson in Modern Science in Bible Lands London (1888) Pp. 449-450
The Ramban comments on Leviticus 26:32
Similarly, that which He stated here, and your enemies that shall dwell therein shall be desolate in it, constitutes a good tiding, proclaiming that during all our exiles, our Land will not accept our enemies. This also is a great proof and assurance to us, for in the whole inhabited part of the world one cannot find such a good and large Land which was always lived in and yet is as ruined as it is [today], for since the time that we left it, it has not accepted any nation or people, they all try to settle it, but to no avail.
The land of milk and honey turning into a desert, is a phenomenon unique in the annals of history.
