Unsustainable agriculture is one of the reasons for desertification. Deforestation, sedentary cultivation of lands that normally only support pastoralism, groundwater depletion, these can trigger desertification. The most affected are indeed the areas that have a more precarious balance like drylands. But this comprises almost half of the Earth's freely accessible land surface. Being in a rainy region covers up for the issue, gives you a wider margin for error.

That's not a good reason to screw with it wherever and whenever we can. This is more appropriate to say in the context of humans being gone because otherwise we have so many ways to let life only find the way to extinction.
