Economic Impacts of Climatic Changes on Some Vegetable Crops in Egypt

This study was carried out to assess the economic impacts of climate change on some major vegetable crops (potato, tomato and green bean) in Egypt and to predict the production, intended cultivated area and water requirements under increasing population annual growth rate of 2.07% with and without climate change during the period of 2025s2100s according to SRES A and B scenarios. The statistical and economical 2 2 analyses were used to analyze the data, such as regression analysis and paired t-test.The results showed that increase of consumption gap for studied crops (potato, tomato and green bean) as a result of population growth as well as climate change impacts. The consumption gap will be increased from 1396.6, 3415.7 and 103.8 to 8658.7, 21177.5 and 630.3 thousand tons for potato, tomato and green bean, respectively, through the period of 2025s-2100s compared to the year of 2011. The cultivated area should be increased in order to decrease these consumption gaps by 1128.9, 1790.8 and 209.2 thousand feddan for the three crops, respectively. The results indicated that total water requirements will be increased to reach about 1450.0, 4404.2 and 413.9 Mm for potato, 3 tomato and green bean, respectively, in the year of 2050s as a result of increase ET by 9.0% and the target 0 cultivated area for the three crops in order to decrease the consumption gap.
