"China faces severe resource and environmental constraints. For example, population pressure, urbanization and rising prosperity have resulted in the loss of some of China's best farmland. Since the mid-1990s, China has suffered a loss of about 8.3 million hectares of arable land, or about 6.5 percent of the country's total arable area. The implied loss of output is even greater than this contraction implies, since the process of net land contraction conceals the disappearance of disproportionately large amounts of land in the most fertile regions of coastal China, where economic growth and structural change have been most marked. Land degradation, through desertification and the creation of enormous dust bowls, has also become a major problem."..................full story here:
