Royal Rainmaking Project

The Thailand Royal Rainmaking Project (Thai: โครงการฝนหลวง, RTGS: khrongkan fon luang) was initiated in November 1955 by King Bhumibol Adulyadej. Thai farmers repeatedly suffered the effects of drought. The king resolved to do something about it and proposed a solution to the dearth of rain: artificial rainmaking, or cloud seeding. The program is run by the Department of Royal Rainmaking and Agricultural Aviation. There is no impact evaluation or effectiveness reported.
