摘要： The use of controlled burning to clear agricultural land is a common practice in many parts of the world. This practice constitutes an important source of air pollution from agriculture. By exploring crop production cycles in China, this paper examines the impact of air pollution from agricultural fires on human cognitive health by linking household health survey data with fire points from remote sensing. The analysis shows a significant negative impact of fire points on cognitive health: respondents (aged 55 and above) in counties with high frequencies of fire points have scores 5.1% lower in a general cognition test, and recall 11.8% fewer objects in the delayed memory test. This impact is detected among respondents living in downwind counties but not the upwind counties. The cognitive impact from agricultural fires implies additional health costs from climate change that increases wildfire risks.
