By using county-level cross-sectional data on agricultural net revenue, climate, and other economic and geographical data for 1275 agriculture-dominated counties in the period of 1985-1991, we find that both higher temperature and more precipitation will have overall positive impact on China's agriculture. However, the impacts vary seasonally and regionally. Higher temperature in all seasons except spring increases agricultural net revenue while more precipitation is beneficial in winter but is harmful in summer. Applying the model to five climate scenarios in the 2020s and 2050s shows that the North, the Northeast, the Northwest, and the Qinghai-Tibet Plateau would always benefit from climate change while the South and the Southwest may be negatively affected. For the East and the Central China, most scenarios show that they may benefit from climate change. In conclusion, climate change would be beneficial to the whole China.展开更多

It is of great importance to estimate the effects of carbon sequestration measures taken to mitigate or adapt to impacts of climate change with proper economic outcome models. This paper aims to measure the effects of the most commonly used carbon sequestration measures, fertilization and irrigation, on agricultural production in the North China Plain.展开更多

文摘For thousands of years, the North China Plain has been one of the most productive agricultural regions of the country, and the future of this region will be determined in large part by how global climatic change impact regional conditions and by actions taken to mitigate or adapt to impacts of climate change. It is of great importance to estimate the effects of carbon sequestration measures taken to mitigate or adapt to impacts of climate change with proper economic outcome models. This paper aims to measure the effects of the most commonly used carbon sequestration measures, fertilization and irrigation, on agricultural production in the North China Plain.
