摘要

本研究探讨了气候变化对泰米尔纳德邦西部地区(WZ)高粱可能产生的影响,西部地区包括哥印拜陀地区、提鲁布尔地区和埃罗德地区。DSSAT 作物模拟模型用于模拟高粱产量,其中考虑了不同的播种日期和施肥量。缩小尺度的 CCSM4 气候模型数据用于 1991 年至 2020 年的历史基线期,以及 RCP 4.5 情景下 2021 年至 2099 年的未来预测数据。主要研究结果表明,预计近本世纪(2021-2040 年)的产量下降幅度为-1.3%至 12.5%,本世纪中期(2041-2070 年)为-6.2%至-23.7%,本世纪末(2071-2099 年)为-12.6%至-30.5%。本世纪末(276.83 千克/公顷-1)、本世纪中叶(178.16 千克/公顷-1)和本世纪末(89.4 千克/公顷-1)的高粱产量降幅较大。研究结果表明,增加施肥量对高粱的生产率略有积极影响。这项研究强调了气候变化对泰米尔纳德邦粮食安全构成的重大威胁,并强调需要采取适应战略来保护农业生产力。

Assessment of climate change impact on sorghum (Sorghum bicolor) production and adaptation strategies in the western zone of Tamil Nadu
This study examines the possible effects of climate change on sorghum in the western zone (WZ) comprising Coimbatore, Tirupur, and Erode districts of Tamil Nadu. The DSSAT crop simulation model was used to simulate sorghum yields with considering various planting dates and amounts of fertilizer application. The downscaled CCSM4 climate model data was utilized for the historical baseline period spanning from 1991 to 2020, as well as for future projected data from 2021 to 2099, under the RCP 4.5 scenarios. The key findings indicate that there is a projected yield decline range of -1.3% to 12.5% for the near century (2021-2040), -6.2% to -23.7% for the mid-century (2041-2070), and -12.6% to -30.5% for the end century (2071-2099). The sorghum yield experiences a high decrease at the end of the century (276.83 kg ha-1), mid-century (178.16 kg ha-1), and lastly in the near century (89.4 kg ha-1). The study revealed that a enhanced fertilizer application can have a minor positive effect on sorghum productivity. The study underscores the significant threat that climate change poses to food security in Tamil Nadu and emphasizes the need for adaptation strategies to protect agricultural productivity.
