For trees from seeds try moringa oliefera, leucania leucocephala, gliricidia sepium, mesquites and acacias. These are all drought tolerant nitrogen fixers available cheap on ebay, and with good germination rates in our climate. Soak the seeds for 36 hrs in warm water (very hot to boiling for acacia) Get a clear plastic sandwich box from the Chinese shop. Place the lid upside down and put damp kitchen towel on it, seeds on that, then click the box onto the lid so u've got a "greenhouse" and stick it in the sun. Change the paper towel every day or two to avoid mouldy seeds. Any that sprout, stick em in soil in a pot in full sun. Any not sprouted after ten days, soak them another 24 hrs and repeat.
Also put some aloe veras and prickly pears in the patch of desert you are working with, these help add organic material to the ground, and protect against wind erosion.
I've put a couple of palms and yuccas in too, they look nice but they're not as efficient users of water, or fast growers, or as good for the "soil" as the other plants I've mentioned.

We've had 3 rainfalls in the last month, which is our first series of summer rains since I got here 5 years ago. It's been enough to irrigate our trees for another 4.5 years, so I may actually consider planting more in the winter and adding to our water budget.
