....growing Chinese population, land reclamation for agricultural purposes increased in the last decades. In the less densely populated areas, large areas of non agricultural land have been converted into rainfed and irrigated farmland, mainly in marginal zones between cropping and non cropping areas (Sun and Li, 1997). During the 1950 s, the area of cultivated land increased rapidly due to largescale reclamation and economic development (Fischer et al. 1998) Due also partly to extended irrigation practices, between 1960 and 1984, the area of cultivated land expanded from the range of 104 to 111 million ha to ....
.... However, the impressive growth in agricultural output was paid for in terms of soil erosion, water quality degradation, and water scarcity (Fischer et al. 1996) The present decline in the area of arable land can only be counteracted by intensified use of agricultural inputs and technology (Sun and Li, 1997). This increases the risk for land degradation and water pollution. In the last four decades, the Chinese government, used to distort agricultural input and product markets to the point that unnecessary and costly environmental degradation undermines future food production. In fact, increased use ....

....with land data from State Statistical Bureau of China Land data published by the State and Provincial Statistical Bureaus (SSB) are the traditional source of land data in China. In general, SSB data are regarded as the official and most authoritative statistical estimates. Some authors, such as Li and Sun (1997), used the data from the China Statistical Yearbook edited by SSB to model the driving forces of cultivated land conversion in China. Due to different division of labor between SSB and SLA, land data communicated by SLA typically contain more detail. Also, there are obvious 4 differences in ....
