Psalms 107:33-36

Whenever he chooses he can dry up a river and turn the land into a desert. Or he can take a fruitful land and make it into a saltwater swamp, all because of the wickedness of those who dwell there. But he also can turn a barren wilderness into an oasis with water! He can make springs flow into desert lands and turn them into fertile valleys so that cities spring up, and he gives it all to those who are hungry.
