Abstract: In order to conduct comprehensive analysis of “grazing ban” policy and its impacts, the authors applied NDVI data with MODIS satellite information to analyze the impacts of “grazing ban” policy on vegetation biomass with 8 years of NDVI data comparison between grazing and non-grazing pasturelands in New Barag Right Banner. At the same time, semi-structure interviews were conducted with herder families to reflect their reaction towards the policy impacts. The results indicate that even though there are relatively small differences in the biomass production between grazing and non-grazing pasturelands, the differences are not obvious enough to influence decisive policy implementation. In addition, the findings demonstrate that the level of rangeland biomass production has been highly fluctuated within 4 year duration after the “grazing ban” policy implementation. Therefore, it does necessarily approve that “grazing ban” policy has improved overall grassland quality. As matter of fact, the policy implementation has disturbed the original interaction between livestock and grassland ecosystem, and thus it may impose negative effects on the rangeland quality.
