Climate Change and Its Impact on Crop Yields in Tibet, China

Researching climate variability and anomaly have become an important task for international researchers. The primary emphasis of this paper is to outline the Tibetan climate change and its impact on crop yields. Climate has great influence on agricultural productions in Tibet. The Tibetan plateau is unique both in climatical and agricultural respects. The results are highlighted by three main points: 1. From the 19th century, the most severe calamity is heavy snowstorm in Tibet, especially in the northern parts of Tibet. 2. The climate in Tibet has the trend of becoming dry and warm. 3. In a long period, the variation of crop yields corresponds with the long-period fluctuation of temperature. The change of crop yields in a short term corresponds to precipitation, particularly the one in May and June.
