As the majority of the Thai people depend on agriculture, Thailand needs a large amount of water for farming activities. Formerly, Thai farmers had to wait for seasonal rain to grow crops. As a result, the crop production usually suffered from drought as there was not enough rainfall during the long dry season. HM King Bhumibol Adulyadej learned about this problem by travelling to even the remotest corner of the country. Out of the purpose to help his people, the King devoted himself to studying and researching artificial rainmaking techniques and donated his private funds to launch the Royal Rainmaking Project.
