Abstract
The report focuses on two dimensions of the energy issue in small farm rice production systems. The energy requirements of three alternative rice production systems used by most small Asian farmers are identified by task and energy source and the energy levels and components of each system compared. Human energy contributes a small portion of total energy input into most traditional Asian rice farming systems. As food production systems modernize, they become less energy efficient and more dependent on commercial energy.ADDITIONAL ABSTRACT:The energy requirements of traditional, mechanical and transitional rice production farming systems used by the majority of Asian farmers were analysed. The human, animal, machine, seed, fertilizer, insecticide and herbicide inputs for each stage of land preparation, sowing, crop care, harvesting, threshing and drying were considered. As the production systems modernized they became less energy efficient and more dependent on commercial energy
