• The New Theory is a production system based on Sufficiency Economy by which farmers can subsist at an economical level first, provided that the community must unite and cooperate in helping one another along the line of long khaek or mutual-help tradition to cut down on labor expenses.
• Since rice is the staple food consumed by every household, it is estimated that each family must grow rice on approximately 5 rai (8,000 square meters) of land to have enough rice for year-round consumption without having to buy it at an expensive price, thus enabling them to be self-reliant.
• There must be a sufficient reserve of water to be used for cultivation in the dry season or during the dry spell. Therefore, it is necessary to set aside a part of the land to dig a pond on the principle that there must be enough water for cultivation the whole year round. According to His Majesty the King’s calculation, to cultivate 1 rai (1,600 square meters) of land requires about 1,000 cubic meters of water. So, for growing 5 rai of rice and 5 rai of field crops or fruit trees (10 rai in all) there must be about 10,000 cubic meters of water per year.
