For the record, back of a napkin calculation says: 500000km2 of medium density forest of medium water requirement trees needs ~100MW of energy just for desalination. Then the construction of the irrigation grid, maintaining it, pumping the water, staffing the initial works, machinery, etc. goes on top of that.
