Modern agriculture in Taiwan depends mostly on high inputs of chemical fertilizers and chemical pesticides for pest control and tends towards monoculture of crop varieties. These practices have increased overall productivity, but they have also led to overproduction of certain crops in Taiwan, which has reduced farmers' profit because of inevitable drop in farm's product prices. Intensive production also has to accelerate air pollution and soil erosion and to result in contaminating ground water as well as underground water.The history of the long walk of organic farming in Taiwan in the past 100 years has been reviewed in this paper. Our old ancestors began with a looting-type farming without fertilizer application→doing-nothing-type farming→natural-farming→use of chemical fertilizer+chemical pesticides farming→organic farming. In the past 100 years, the people in Taiwan, mostly dependent on chemical based farming and only recent 20 years scientific organic farming has been emphasized. As the results of efforts made by research units, government agencies and farmers as well as consumers, organic farming is now on the right track same as that of developed countries such as USA, Europe and Japan.In addition to development of technology of organic farming by the researchers, various regulations and laws governing organic farming have been promulgated by the authority of Taiwan in recent years. They include: Standard of organic production; Regulation governing the unit of organic certification; Standard of organic production - Crops; Standard of organic production - Livestock Production; Regulation governing certification of organic food processing. Eleven organizations have been certified to be eligible to assume duties of organic product certification. Due to the above mentioned measures, the number of organic shops increased rapidly including many chain stores (such as Li-Jen, Little Green Town and Santa Cruz, cotton field etc.) around Taiwan. This indicated that the business of organic farming is successfully carried out in Taiwan today.
