Abstract

Given that nearly half of the Indian labor force is employed in agriculture, extreme weather events may harm most of the country’s population. By exploiting annual variation within Indian districts, I test whether greater temperature fluctuations significantly decrease the output value of 13 major crops. I find that a 1°C deviation above the annual mean temperature leads to a 21.3 percentage point decline in output value for a given year, indicating substantial losses from large fluctuations in temperature. I also find evidence that proportion of crop area irrigated and fertilizer usage mitigates the negative impacts of temperature shocks.
气候冲击对农作物产量的影响:来自印度的证据
鉴于印度近一半的劳动力从事农业,极端天气事件可能会损害该国大部分人口。通过利用印度各区的年变化,我测试了较大的温度波动是否会显著降低13种主要作物的产值。我发现,高于年平均温度1°C的偏差会导致给定年份的产值下降21.3个百分点,这表明温度的大幅波动造成了重大损失。我还发现有证据表明,作物灌溉面积的比例和肥料的使用减轻了温度冲击的负面影响。

期刊介绍: The purpose of the Review is to foster and disseminate professional thought and literature relating to the economics of agriculture, natural resources, and community development. It is published twice a year in April and October. In addition to normal refereed articles, it also publishes invited papers presented at the annual meetings of the NAREA as well as abstracts of selected papers presented at those meetings. The Review was formerly known as the Northeastern Journal of Agricultural and Resource Economics
