Abstract
PurposeThe purpose of this paper is to assess the impacts on production of five fruit crops from 1961 to 2018 of energy use, CO2 emissions, farming areas and the labor force in China.Design/methodology/approachThis analysis applied the autoregressive distributed lag-bound testing (ARDL) approach, Granger causality method and Johansen co-integration test to predict long-term co-integration and relation between variables. Four machine learning methods are used for prediction of the accuracy of climate effect on fruit production.FindingsThe Johansen test findings have shown that the fruit crop growth, energy use, CO2 emissions, harvested land and labor force have a long-term co-integration relation. The outcome of the long-term use of CO2 emission and rural population has a negative influence on fruit crops. The energy consumption, harvested area, total fruit yield and agriculture labor force have a positive influence on six fruit crops. The long-run relationships reveal that a 1% increase in rural population and CO2 will decrease fruit crop production by −0.59 and −1.97. The energy consumption, fruit harvested area, total fruit yield and agriculture labor force will increase fruit crop production by 0.17%, 1.52%, 1.80% and 4.33%, respectively. Furthermore, uni-directional causality is correlated with the growth of fruit crops and energy consumption. Also, the results indicate that the bi-directional causality impact varies from CO2 emissions to agricultural areas to fruit crops.Originality/valueThis study also fills the literature gap in implementing ARDL for agricultural fruits of China, used machine learning methods to examine the impact of climate change and to explore this important issue.

Effect ofThe magnitude of impacts on agricultural systems typically fluctuates according to climate change geographic factors
3.5 Results of Granger causality test This analysis has used Granger’s pairwise causality test to examine the causal direction of the variables; the causal links were analyzed between an FHA, lnTFY, ln CO2, lnRP, lnEC, lnALF and lnTFP
The null hypothesis of energy consumption does not increase the quality of fruit crops which is rejected at 5%
Summary
The magnitude of impacts on agricultural systems typically fluctuates according to climate change geographic factors. China is one of the largest centers of farmed plant origin in the world. Today China is inherent in several deciduous fruits, such as apples, bananas, citrus, pears on fruit and grapes. The impacts of climate change on-farm yields in various parts of the world have been explored in economic literature (Chandio et al, 2020). There have been several previous studies on agriculture. Liu et al (2015) describe the importance of vegetation, the effects of climate changes on vegetation growth There have been several previous studies on agriculture.
