Realizing the problem of soil degradation affecting the
region, His Majesty the King came up with an idea of setting
up the first royal development study centre, the Khao Hin Sorn
Royal Development Study Centre, on 8 August 1979 in Phanom
Sarakham District, Chachoengsao Province. This has set the
idea for establishing other royal development study centres.
It can be said that the history of the royal development study
centres began at Khao Hin Sorn.
