The Effect of Climate Change on Wheat and Maize Crops in Egypt

: The research aimed to identify the development of each of the maximum and minimum temperature and relative humidity of the winter and summer seasons in Egypt and their stability during the period (2000-2021), and the extent of the impact of this development on the feddan productivity of wheat and maize crops in Egypt, and the consequent economic effects. Among the results, the productivity of a feddan of wheat crop decreased by 0.05 tons, with an increase in the maximum temperature in the winter season by one degree Celsius, The productivity of a feddan of the wheat crop decreased by 0.06 tons, with an increase in the minimum temperature in the winter season by one degree Celsius, It also showed a decrease in productivity, The feddan of the wheat crop increased by 0.02 tons, with an increase in relative humidity in the winter season by 1%. The results also showed a decrease in the productivity of the feddan of the maize crop by 0.06 tons, with an increase in the maximum temperature in the summer season by one degree Celsius
