The impact of climate change on the production of some field crops

The study of the factors affecting the agricultural production of the most important crops under study, whether economic or environmental variables and then to identify the fluctuation of agricultural production of the most important strategic crops, whose production is affected by climate variability, where the problem of the study was the negative impact of the phenomenon of climate change and environmental pollution on agricultural production, especially In light of contemporary environmental and economic variables. The objective of the research was to identify the most important environmental and economic factors responsible for bringing about changes in agricultural production. Reviewing the most important productive activities constituting plant production in the Arab Republic of Egypt and the importance of each activity for the average monetary value of both agricultural and plant production during the period (2013-2017). Field crops were ranked first with an average value of LE 107.15 billion representing about 38.34% of the total average value of agricultural production, representing about 65.3% of the value of plant production during the period (2013-2017). The second, where the average value of about 30.51 billion LE, representing about 30.51% of the total average value of agricultural production and represents about 18.9% of the average value of plant production. The most important factors affecting Egyptian wheat production during the period (2003-2017) are the cultivated area of wheat crop, average minimum temperature and average bone temperature. The model showed a direct correlation between the amount of wheat production and the cultivated area of the wheat crop. Results An increase of 90% in total wheat production by increasing the cultivated area of wheat by 10%. The model also showed a positive correlation between the quantity of wheat production and the average temperature of the smallest, where the results show an increase in total wheat crop production by about 10.4%, with an increase in the average small temperature by 10%. The model also showed an inverse relationship between the quantity of wheat crop production and the average bone temperature, where the results indicate a decrease in total wheat production, as the increase of bone temperatures by 10% leads to a decrease of agricultural production by 27% during the study period.
