The Effect of Sloping Land Conversion Program on Soil Erosion in Shaanxi Province, China: A Spatial Panel Approach

Soil erosion is a land degradation process that may threaten the sustainability of ecosystem as well cause severe social and economic problems. The studies on effect ecological restoration policies soil have been documented, while spatial relationships spillover effects rarely scrutinized, though it great policy implications in control. Based analysis spatio-temporal evolution 107 counties Shaanxi Province with Revised Universal Loss Equation, this study employs panel Durbin model (SDM) multi-source data for from 2000 to 2015 investigate Sloping Land Conversion Program (SLCP) control investment SLCP. results show during 2000–2015, average amount exhibited significant downtrend contributed by continuous demonstrate own effect, control, positive. A 0.1 billion CNY increase county will result reduction total 288.69 thousand t/a, which 63% direct local 37% neighbors. Moreover, rainfall has positive moderating mitigation SLCP at scale; marginal contribution less greater than more rainfall. These findings contribute further our understanding long-term transboundary governance.
