God has full control over nature. And can take back His blessings should He desire, or render them of no avail. 

A fruitful land into barrenness, for the wicked of them that dwell therein.

Should a nation not humble herself and pray and seek the face of the Lord and turn from her wicked ways, then her mountains, prairies, and oceans will become a land of barrenness. God will not withhold judgment from those who live wickedly before Him.

But should repentance come, He can just as easily turn the wilderness into a standing water, and dry ground into water-springs. The whole earth is at the mercy of the Lord. God who brings judgment on wickedness {Psa. 107: 31-35}.
