No part of the world is nowadays sufficient rain. Because they are not performing yajna. Sometimes it is seen that over-rain, overflood, not systematic. But if you perform yajna, there will be systematic rainfall, which you can utilize properly. Yajnad bhavati parjanyah. [Bg. 3.14]: "Rains are produced by performance of yajna {sacrifice}."
