[1] The supply and control of water is crucial to the productivity of rice land, especially when planted with high-yield seed varieties.
Evidence for the earliest cultivation, however, comes from eighth century stone inscriptions from the central island of Java, which show kings levied taxes in rice.
Divisions of labour between men, women, and animals that are still in place in Indonesian rice cultivation, were carved into relief friezes on the ninth century Prambanan temples in Central Java: a water buffalo attached to a plough; women planting seedlings and pounding grain; and a man carrying sheaves of rice on each end of a pole across his shoulders (pikulan).
In the sixteenth century, Europeans visiting the Indonesian islands saw rice as a new prestige food served to the aristocracy during ceremonies and feasts.
Once covered in dense forest, much of the Indonesian landscape has been gradually cleared for permanent fields and settlements as rice cultivation developed over the last fifteen hundred years.
[1] Various governmental policies included the dissemination of high-yield seed varieties through government-sponsored extension programs, direct investment in irrigation facilities, and control of the domestic price of rice through the National Logistical Supply Organization (Bulog), the government rice-trading monopoly.
[1] High-yield varieties were promoted together with subsidized fertilizer, pesticides, and credit through the "mass guidance" or Bimas rice intensification program.
Bulog influenced the domestic rice price by operating a buffer stock on the order of 2 million tons during the 1980s.
