Which is easier to control, saline-alkali land or desert?

1, because at least some oases and water sources can appear in the desert, and even cacti can't survive in saline-alkali land.

2. The harm of saline-alkali land is more serious than that of desert, and it is more difficult to control. Animals and plants can not survive in saline-alkali land, and it is even more difficult to control in the later stage. The salt content is too high to be directly introduced into desert for sand control.
