Abstract

We examine the effects of the federal crop insurance program on crop production under extreme heat using farm-level data from Kansas. We find that insured dryland corn is 38% more sensitive to extreme heat than uninsured dryland corn. Results also suggest that a uniform $+ 1 °$ C warming scenario leads to yield reductions of 16.7% (11.8%) for insured (uninsured) corn production; and 6.0% (4.4%) for insured (uninsured) wheat production. Warming had a stronger impact with reduced rainfall, especially on insured farms compared with uninsured farms, while altered growing seasons showed potential benefits for wheat but limited improvements for corn.

农作物保险会影响气温变暖对农作物产量的影响吗？农场层面的分析

我们使用来自堪萨斯州的农场数据来检验联邦作物保险计划对极端高温下作物生产的影响。我们发现，有保险的旱地玉米对极端高温的敏感性比没有保险的旱地玉米高38%。结果还表明，统一的升温情景导致投保(未投保)玉米产量下降16.7% (11.8%);投保(未投保)小麦产量为6.0%(4.4%)。气候变暖对降雨量减少的影响更大，特别是对有保险的农场，而对没有保险的农场，而改变生长季节对小麦有潜在的好处，但对玉米的改善有限。
