Environmental Protection in China

Land-Use Management

Edited by Jeff Bennett, Xuehong Wang and Lei Zhang

Faced with intensified environmental degradation and decreased agricultural land productivity, the Chinese government has sought policy interventions to reverse both of these negative trends. Among the policy instruments is the Conversion of Cropland to Forest and Grassland Program (CCFGP) that aims to change the pattern of agricultural land use in 25 provinces and autonomous regions across China. This book provides the most comprehensive assessment of the CCFGP undertaken to date. It allows the consideration of fundamental questions pertaining to the sustainability of the land use changes brought about by the CCFGP, its cost effectiveness and the prospects for policy evolution. Contributions from a wide range of economists and scientists in the book provide policymakers in the Chinese government with relevant information with which to pursue more effectively agro-environmental goals.

Chapter 6: Valuing Run-off Reductions

Jeff Bennett, Lei Zhang, Yangwen Jia, Yaqin Qiu and Xuehong Wang


Jeff Bennett, Lei Zhang, Yangwen Jia, Zuhao Zhou, Yaqin Qiu, Xuehong Wang and Zhitao Zhang INTRODUCTION The Conversion of Cropland to Forest and Grassland Program (CCFGP) was initiated primarily as an ecological restoration programme to tackle the environmental degradation in Western China through increasing vegetation along the Upper Reach of the Yangtze River and the Upper and Middle Reaches of the Yellow River (SFA and SDPC 2000). Since its implementation in 2000, the land-use change induced by the Program in the Northwest Provinces has brought about observable biophysical changes both on-site and off-site. Increased vegetative cover has changed the appearance of the countryside. Wind erosion has decreased with consequential reductions in sandstorm severity and frequency. Biodiversity enhancement in the revegetated areas has been evidenced (Du and Guo 2001; Ge et al. 2001; Li et al. 2001; Shen, Ma and Li 2001; Zhao 2001). However, along with these impacts, research conducted by the China Institute of Water Resources and Hydropower Research (Jia, Zhou and Qiu 2006) has found reductions in run-off resulting from the CCFGP. Projections of further run-off reductions have been made for a time period extending to year 2020. The reduced run-off is expected to have impacts on both water availability and flooding risks in the Yellow River Basin. Reduced run-off can have both positive and negative effects. On one hand, decreased run-off can reduce soil erosion and sediment loads in the Yellow River, consequently reducing flooding risks. On the other hand, however, decreased run-off can have important repercussions...
