Sustaining the Gradient Of Vegetation Growth In Any Desert Is Important. Grab The Chance. Sustain by manual watering?

I wonder.

I think the ?only way to get sustainable rain in the arid desert is to manually water those places which has gotten som rain recently. When the rain hits those places again you will have a ?secondary effect. Then a third.

The idea is that after this the weather ?network would have picked up on the vegetation changes in that place to direct more sustainable natural rain.
