China supports nearly one quarter of the world's population with produce derived from only one 15th of the total land area of the earth. Furthermore, some 80% of the Chinese population is engaged in agriculture and related sectors. This massive scale of production, processing and distribution requires an extensive network of organizations concerned with research, education, administration, and extension. The research network operates at the national, provincial and prefectural levels and involves a workforce of some quarter of a million professional and technical personnel.
