China's urban population is wit- nessing a continuous increase, with the current number of regular urban resi- dents standing at 622,000,000, and the urbanization is still accelerated at an annual rate of 0.8%. Off-farm workers flooding into cities have turned from grain producers to consumers. When about 11 million people are squeezed into the urban population every year, it is a headache for anyone to consider how to satisfy the increasing demands for food by counting on the farming sector, propped up mainly by the el- derly and weak, females and children. Han Changfu, minister of the Minis- try of Agriculture, pointed the problem out in an interview.
