Although China's economic reform began in agriculture, its early success has not been sustained by continuing efforts to promote agricultural development, according to a professor of agricultural and resource economics at UC Davis."Rather, the agricultural sector has supported the industrial sector's high rate of growth, but this situation cannot continue," says Colin Carter, co-author of the new book "China's Ongoing Agricultural Reform." "There needs to be fundamental changes in China's agricultural policy in order for the nation to feed its 1.2 billion people," he says.China is still predominantly an agricultural country. Sixty percent of its labor force is engaged in farming and three-fourths of its population lives in rural areas, Carter notes. In the book, Carter and co-authors Funing Zhong and Cai Fang present a systematic study of China's agricultural policy including the causes of the slowdown in that country's agricultural output in the last decade.
