摘要

气候变化对地球生态系统造成严重破坏，影响天气模式，破坏粮食安全。本文研究了气候变化对印度农业的影响，以及东部地区粮食产量的气候敏感性。该研究使用一组实物作物产量并分析1990年至2017年的地区级数据，估计了具有外部季节性天气变量的特定粮食的农业生产函数。这些参数包括平均温度、降雨量、蒸散量和风速。按空间分列的地区一级数据提供了来自较低行政单位的信息，形成了有待审查的更广泛的情况。研究表明，气候变化显著影响东印度农业，其结果与在印度进行的其他邦和区级研究一致。一年中不断变化的天气模式极大地影响了作物生产，扰乱了粮食供应和质量。因此，该研究进一步扩大了结果对区域间不平等的影响，并建议了纠正措施。

HOW CHANGES IN CLIMATE AFFECT CROP YIELDS IN EASTERN INDIA

Climate change wreaks havoc on the planet’s ecosystem, affects weather patterns and undermines food security. This paper investigates the effect of changing climate on Indian agriculture, and the climate sensitivity of food grain yield in the eastern region. Using a panel set of physical crop yields and analyzing district-level data from 1990 to 2017, the study estimates agricultural production functions for specific food grains with extrinsic seasonal weather variables. These include average temperature, rainfall, evapotranspiration and wind speed. Spatially disaggregated district-level data provides information from low administrative units, creating a broader picture to be examined. The research indicates that climate change significantly affects east Indian agriculture, and its outcomes are consistent with other state and district-level studies conducted in India. Changing weather patterns over the year considerably influence crop production and disrupt food availability and quality. Hence, the study further expands the implications of results for inter-region inequality and recommends corrective measures.

期刊介绍： Climate Change Economics (CCE) publishes theoretical and empirical papers devoted to analyses of mitigation, adaptation, impacts, and other issues related to the policy and management of greenhouse gases. CCE is specifically devoted to papers in economics although it is understood that authors may need to rely on other fields for important insights. The journal is interested in papers examining the issue at every scale from local to global and papers from around the world are encouraged. CCE is also interested in both original research and review papers and welcomes comments discussing previous articles.
