Abstract

The response of agricultural productivity anomalies to drought stress plays a crucial role in the carbon cycle within terrestrial ecosystems and in ensuring food security. However, detailed analysis of how global agricultural productivity anomalies response to drought stress, particularly within irrigated and rainfed agricultural systems, remains insufficient. In this study, the impact of drought stress on agricultural productivity anomalies during the growing season (zcNDVIS), across both irrigated and rainfed agriculture, were analyzed using a suite of hydro-climatic variables. Specifically, the investigation utilized the multi-scalar Standardized Precipitation Evapotranspiration Index (SPEI), the Multivariate ENSO Index (MEI), and the Madden-Julian Oscillation (MJO). Meanwhile, the relationships between hydroclimatic variables and zcNDVIS were analyzed at one, two, three and four months before the ending of growing season (EOS). Results showed that (1) the percentages of significant (p<0.1) drying trends varied across the globe from 8.30% to 13.42%, 6.50% to 14.63%, 6.52% to 14.23%, and 6.47% to 14.95% at one-, two-, three-, and four-month lead times before EOS, respectively, during 2001–2020, which represented by the multiscalar SPEI. This observation highlights that most regions across the globe tend to be arid, which could significantly impact agricultural productivity; (2) the global mean correlation coefficients (rmax) for SPEI-1, SPEI-3, SPEI-6, SPEI-12 (indicating SPEI at 1-, 3-, 6-, and 12-month lags), MEI, and MJO with zcNDVIS ranged between 0.24–0.25, 0.27–0.28, 0.25–0.26, 0.21–0.22, −0.02–0.01 and 0.06–0.11, respectively, across both irrigated and rainfed agriculture system from 2001 to 2020. Agricultural productivity anomalies demonstrated a significant correlation with drought stress. The strongest correlations were noted for SPEI-3 and SPEI-6, suggesting a delayed response of crops to drought conditions. This indicates that agriculture ecosystem experiences prolonged disturbances due to abiotic drought stress; and (3) the percentages of regions that showed significant correlations (p<0.1) between zcNDVIS and drought indices (SPEI-1, SPEI-3, SPEI-6, and SPEI-12), as well as climate indices (MEI and MJO) ranged as follows: 14.77%–20.27%, 21.51%–32.55%, 22.60%–35.68%, 21.89%–35.16%, 7.93%–11.20% and 9.44%–17.94%. Quantitatively identifying how zcNDVIS spatially responds to hydro-climatic variables can help us better understand the impact of drought on agricultural productivity anomalies worldwide.

全球农业生产力异常对灌溉和雨水灌溉农业干旱压力的响应
农业生产力异常对干旱胁迫的响应在陆地生态系统的碳循环和确保粮食安全方面发挥着至关重要的作用。然而,对于全球农业生产力异常如何响应干旱胁迫,特别是在灌溉和雨水灌溉农业系统中,详细分析仍然不足。本研究利用一系列水文气候变量,分析了干旱胁迫对灌溉农业和雨养农业生长季节(zcNDVIS)农业生产力异常的影响。具体而言,研究利用了多尺度标准化降水蒸散指数(SPEI)、多变量厄尔尼诺/南方涛动指数(MEI)和马登-朱利安涛动(MJO)。同时,分析了生长季结束前 1 个月、2 个月、3 个月和 4 个月水文气候变量与 zcNDVIS 之间的关系。结果表明:(1) 2001-2020 年间,在 EOS 结束前 1 个月、2 个月、3 个月和 4 个月,全球显著(p<0.1)的干旱趋势百分比分别为 8.30% 至 13.42%、6.50% 至 14.63%、6.52% 至 14.23% 和 6.47% 至 14.95%,这是由多尺度 SPEI 所代表的。这一观测结果表明,全球大部分地区趋于干旱,这可能会严重影响农业生产力;(2)SPEI-1、SPEI-3、SPEI-6、SPEI-12(表示滞后 1、3、6 和 12 个月的 SPEI)、MEI 和 MJO 与 zcNDVIS 的全球平均相关系数(rmax)介于 0.从 2001 年到 2020 年,在灌溉和雨水灌溉农业系统中,农业生产率异常分别介于 0.24-0.25, 0.27-0.28, 0.25-0.26, 0.21-0.22, -0.02-0.01 和 0.06-0.11 之间。农业生产力异常与干旱胁迫有显著相关性。SPEI-3和SPEI-6的相关性最强,表明作物对干旱条件的反应延迟。(3) zcNDVIS 与干旱指数(SPEI-1、SPEI-3、SPEI-6 和 SPEI-12)以及气候指数(MEI 和 MJO)之间存在显著相关性(p<0.1)的地区比例如下:14.77%-20.27%、21.51%-32.55%、22.60%-35.68%、21.89%-35.16%、7.93%-11.20% 和 9.44%-17.94%。定量识别 zcNDVIS 如何在空间上响应水文气候变量,有助于我们更好地理解干旱对全球农业生产力异常的影响。
