The Beginning of the “Chang-Hua-Mun ” Royal Initiative Project It all began with a yam when villagers took it to offering His Majesty King Bhumibol Adulyadej during the King royally staying at the Klai Kangwon Palace. Before the King royally returned to Bangkok, he placed the yam on an antique scale. After he royally came back to the Klai Kangwon Palace again, he found that the yam had roots and leaves. Thus he stated “yam can grow everywhere,” and graciously commanded to plant separately it into pots. This is an initial point of the “Chang-Hua-Mun” Royal Initiative Project . By the end of 2008, His Majesty the King graciously donated his own treasury to buy land about 120 rais at the Nong Sua reservoir in Baan Nong Kho Kai, Kaokrapook Sub-District, Tayang District, Petchaburi Province, after that he bought about 130 rais. This land was totally about 250 rais. The area was used for experimenting the plantation of yam and other local plants in Petchaburi Province. At that time, no one knew that this area was belong by the king. After that, agencies from the Ministry of Agriculture and Cooperatives, the Ministry of the Interior, and other have involved in the development of this area. There were improvement of the routes to the project location, electricity, and agriculture. Agricultural aspect was improved such as Nong Sua reservoir, soil, and cropping system of economical plants before this the originally economical plants in Petchaburi province were only turtle lime and eucalyptus. His Majesty the King royally granted a name of the project “Chang-Hua-Mun”Royal Initiative Project. On August 1, 2009, the King performed an inaugural ceremony for the “Chang-Hua-Mun” Royal Initiative Project.
