This paper presents an overview of the current conditions of livestock-related environmental problems in Japan. The former Basic Agriculture Act, which was effective between 1961 and 1999, promoted single cropping, the use of chemicals in agricultural methods, and the use of large-sized machines, which caused problems such as soil impoverishment, replant failure, chemical residue accumulation, ground water pollution, and productivity reduction. Many of these livestock-related environmental problems are closely linked to substances in livestock excreta and excessive nitrogen, which is the prime cause of concern. These problems are related to externality and can be attributed to the overuse of natural resources.
