تأثير التغيرات المناخية (درجات الحرارة و الرطوبة و الأمطار)‎ على بعض المحاصيل الاستراتيجية في مصر (1997-2020)‎

Abstract EN

Research aimed to measure the impact of climatic variables on the production of some strategic crops in Egypt (wheat-rice-maize) and the average per capita during (1997-2020), using descriptive and quantitative statistical analyzes and the general temporal trend.

wheat production was directly affected by the minimum temperature and area by about 0,86-92 million tons and inversely, with rainfall and time about 0,24-0,55 million tons.

for rice, was directly affected by the maximum temperature, area and time by about 57-99-0,44 million tons.

inversely, with minimum temperature and precipitation about 2,2-96,3 million tons.

for maize, it was directly affected by area and time about 57-0,64 million tons.

and inversely with maximum temperature by about 33,5 million tons.

for the average per capita share, the wheat has been directly affected by rainfall, area and production by about 6-31-47 million tons ; and inversely with maximum and minimum temperature, population and time, about 87-21-66-13 million tons.

for rice, was directly affected by production and minimum temperature by about 45-15 million tons ; and inversely with population number, maximum temperature, rainfall rate and time of about 19-17-1,14-4 million tons.

for maize, it was directly affected by production, population and rainfall by about 47-0,5-13 million tons ; and inversely, with the maximum and minimum temperature and time by about 43-61-10 million tons, which led to a reduction in the general trade balance deficit by about 46686 doller million as a result of increase in local production, and increase in the general trade balance deficit by about 7083 doller million as a result of increase in the average per capita share during the study period.
