Abstract

Climate change is a major threat to food security. The determination of policy actions requires accurate estimates of climatic impacts on both crop yields (intensive margin) and cropland area (extensive margin). However, the analysis on the latter has been limited, especially in developing countries. This paper assesses the impact of temperature on land use in China by matching high-resolution satellite data of land use with daily weather data from 1980 to 2010. We find extremely hot weather (daily average temperature above 30 °C) has a long-lasting effect on reducing cropland in China. In addition, we find that non-irrigated land is more susceptible to rising temperatures in the short term; however, irrigated land is subject to a similar impact in the long term. This result suggests that the adaptive effect of irrigation could be limited under persistent rising in temperature.
