I suppose if global warming did happen, which it has been shown to do in the past, in cycles; then many bodies of water would overflow and spill over into dry areas of land in many parts of the world. As a result, these formerly dry areas would produce vegetation and become green.

In a dry land , maybe the water can stay but do not drain coz of non-porous rocks underneath, thereby no process of filtration and no pure water for any living creatures , perhaps the only way to make a dry land porous is by digging away the heavy layers of non-porous rocks for any other purpose for the mankind then water can go in and deep, then the sand and infertile soil must be made fertile with artificial fertilisers, then probably we can make green revolution.

Their are special variety of trees that sustain in low rainfall areas and arid lands these can and should be used to plant them in arid/dry lands and make thse lands green.
Jatropha is a plant that grows in arid areas and used for bio-diesel, there are many other plants which have usage as food too.
