Abstract
Nitrogen flow associated with food production and consumption was estimated for China and India and dietary changes during 45 years from 1961 to 2005 were compared. Per capita protein intake has rapidly increased, especially due to the increase of meat and egg consumption in China since the economic reforms around 1980. In India, per capita intake increased slowly in the 1980s while it tended to decrease after the 1990s. Population increased by 2 times in China and 2.5 times in India in this period of 45 years and there has been a greater demand for food. In order to produce enough food, increasing amounts of chemical fertilizer are being used recently and the nitrogen surplus in farmland is considered to cause an environmental burden. The spatial distribution of nitrogen concentration in river water was estimated by taking the nitrogen leaching from farmland, human waste and atmospheric deposition into consideration for India and eastward Asian countries. It was predicted that wide areas close to the east coast of Northern and Central China were highly polluted with nitrogen and that rivers in the Gangetic Plain and southern part of India had high concentrations.
