内容简介
Which is the real tragedy for grasslands, the Commons or Privatization?
The ‘tragedy’ of commons grassland has sparked a wide debate in which one view contends that private ownership of grasslands does not mitigate the tragedy, but rather it has exacerbated their degradation. 200 kilometers on both sides of the border between China and Mongolia provided a valuable opportunity for examining the tragedy. Along this border there are similar natural conditions, but the grassland use institutions (GLUIs) are quite different on either side. We employed 9957 samples from panel data to identify the impact of GLUIs on grassland, further controlling for the influences of natural factors and human activity. The results show that private ownership of grassland significantly mitigated the tragedy. In Mongolia, with commons grassland, those areas with higher quality pastures degraded the most quickly. However, degradation did not occur in Inner-Mongolia (in China), where grassland and livestock are controlled by individual households
