Assessment of Drought Impact on Main Cereal Crops Using a Standardized Precipitation Evapotranspiration Index in Liaoning Province, China

Abstract: Abstract:Global warming has resulted in increasingly frequent and severe drought and/or precipitation events. Severe drought limits crop water availability and impacts agricultural productivity and socioeconomic development. To quantify drought-induced yield loss during the main crop stages in Liaoning province, China, aspects of drought episodes (magnitude, duration, and frequency) were investigated during the period 1960-2015 using the Standardized Precipitation Index (SPI) and the Standardized Precipitation… Show more

“…First, a comparison of the AD-SPEI crop with the average yields in Vojvodina was made, and then a comparison with the average yields at the municipal level in Vojvodina was made in order to obtain more detailed results on the local level. The comparison of the indices with the crop yields can be found in the studies of numerous other authors (e.g., [6,51,[96][97][98]).…”

“…The correlation between the AD-SPEI crop and the yields of the analyzed crops was estimated based on Pearson's correlation coefficient r at significance levels of α = 0.05 and α = 0.10. The aggregated index values (average values) and average crop yields for the region were used according to the [51][52][53]97,98]. The values of Pearson's correlation coefficient between the AD-SPEI crop and the detrended yields of the analyzed crops are presented in the Table 6.…”

“…As shown in Figure 1, Yunnan Province (21)(22)(23)(24)(25)(26)(27)(28)(29)(30) • N, 97-107 • E) is located in the southwest of China. The province includes eight cities (Kunming City, Yuxi City, Lijiang City, Lincang City, Baoshan City, Zhaotong City, Qujing City, and Puer City) and eight minority autonomous prefectures (Chuxiong Yi, Diqing Tibetan, Nujiang Lisu, Dali Bai, Dai-Jingpo of Dehong, Wenshan Zhuang and Miao, Xishuangbanna Dai, and Honghe Hani and Yi Autonomous Prefecture).…”
