Question

what happens when there is no rainfall for a year

Answer 1

human and plants will die due to femininity

Answer 2

Rivers would dry up, crops would fail and our green and pleasant land would start to look pretty desperate. In fact after just a year without rain, desert conditions would start to occur. Land could be irrigated, but that would mean tapping precious underground reserves. Water companies will start rationing drinking water . If there will be no rain for few decades, all water will keep vaporizing, and ultimately, there will be no water left on earth.
