| Research Abstract |
In semi-arid region, Northeast Asia, the livestock population has rapidly increased in recent years. Excessive grazing due to large numbers of livestock causes severe degradation of natural grassland. Furthermore, the vegetation cover of grassland has been reduced by extensive droughts caused by recent climatic changes in continental East Asia. These changes are likely to result in severe soil degradation and the release of large quantities of soil dust into the atmosphere. This study clarified the degradation of grassland and its influence on Asian dust phenomena.
