Abstract

Agricultural production is affected by climatic changes that may affect agricultural production negatively through decreased productivity of some agricultural crops and some positive effects through increasing the productivity of some crops, which calls for studying the economic effects of climate changes to identify the most important climatic factors that affect the production of olive crops in Matrouh Governorate.




The results of the simple regression analysis of the impact of climate change on the total production of the olive crop in Matrouh Governorate during the period (2000-2018) showed that the increase in the maximum temperature in June by one degree leads to an increase in the total production of the olive crop by 22.139 thousand tons, as it was found. That the rise in the minimum temperature in May by one degree leads to an increase in total production by 23.756 thousand tons, and that an increase in the rate of rainfall in February by one millimetre leads to a decrease in total production by 1.399 thousand tons.
 
 
The results of the statistical assessment of the effect of climatic factors on the total production of the olive crop showed that an increase in the average minimum temperature by one degree leads to an increase in the total production of olives by 35.24 thousand tons as well as an increase in the relative humidity by one degree leading to an increase in the total production of olives in Matrouh governorate Subtracted by 5,742 thousand tons.
In light of the research results, it recommends the following:
- Taking care to improve and develop varieties that are resistant to difficult environmental conditions such as salinity and drought and have the ability to with stand pests and diseases.
- The appropriate annual pruning from average to semi-invasive to reduce the phenomenon of light or overload.
- Attention to irrigation and nitrogen fertilization during periods of exposure and flowering transformation from December to March.
