主要内容
Rural farmers face numerous environmental challenges in their agricultural livelihood. This study examines the impact of particulate matter (PM) pollution on agricultural productivity and evaluates farmers’ adaptive strategies. Using longitudinal representative rural household surveys from China, we find that elevated PM2.5 levels have a large adverse impact on agricultural productivity, yet a mitigated impact on total yield. This mitigation is achieved by a critical but understudied adaptive strategy: reallocating agricultural resources—labor, capital, and land—from labor-intensive to capital-intensive crops. This adaptive strategy reduces at least two-thirds of the original revenue losses caused by air pollution increases. For each 10-μg/m3 increase in PM2.5 levels, we estimate that farmer’s adaptive strategies save 486 billion RMB (USD 75 billion) in revenue losses annually. Policies that support farmers’ adaptions can significantly enhance rural welfare and food security.
