Factors of Soil Formation by Hans Jenny is a classic. In addition to purely geological factors, it also touches on topics relevant to sustainable food production. Figure 123 is pretty damning for monoculture cereal (grass) production, particularly the maize used for "livestock" feed.
But if you don't plant trees, there will continue to be droughts, as trees help to regulate humidity and precipitation. Farmers in drought-prone areas actually plant trees (agroforestry) in order to reduce crop losses due to drought. Even in urban areas, planting trees (especially natives) can have many benefits for reducing the impact of drought. Of course, a diverse forest ecosystem would be most resilient.
