Assessing China's ecological restoration programs: What's been done and what remains to be done?

Abstract

This article surveys the recent literature that assesses China's ecological restoration programs, including the Sloping Land Conversion Program (SLCP) and the Natural Forest Protection Program (NFPP). Our presumption is that the performance of these programs should be determined by their effectiveness of implementation and significance of impact. Implementation effectiveness can be measured with such indicators as land area converted or conserved, and survival and stocking rates of restored vegetation, while impact significance can be gauged by the induced changes in ecosystem productivity and stability, and socioeconomic conditions. Coupling this matrix with an exhaustive search of the publications, we find that: (1) the implementation effectiveness has not been examined as extensively as the impact significance; (2) efforts to assess the impact significance have concentrated on the SLCP, particularly its socioeconomic effects: growth of income, alternative industry, and employment, and likelihood of re-conversion; and (3) most of the socioeconomic studies are based on rural household surveys, and discrete choice and difference in differences models. Future work should pay more attention to the NFPP and other programs, and the environmental impacts and the implementation effectiveness of all of them. To these ends, analysts must gather more field data regarding the evolving ecosystem conditions and socioeconomic information of higher aggregation, and conduct their research across scales and disciplines, with better application of geospatial technology and more effective collaboration. © 2009 Springer Science+Business Media B.V.
