Measuring the Expected Economic Effect of Climate Change on the Sugar Beet Crop Using the Ricardo Model

Climate change affects many of the main sectors in Egypt, especially the agricultural sector. Accordingly, the research problem is to identify these climatic changes in Egypt and its impact on the productivity of the sugar beet crop at the study and thus its impact on the net yield of the crop, which prompted the researcher to make future scenarios for the impact of the crop at the study of these climatic changes in the future. That is why the research aims to measure the expected economic impact of climate change on the sugar beet crop using the Ricardo curriculum, by studying the economic developments of the sugar beet crop, and simulating the effects of climate change in order to reach the sensitivity of this crop of climate change, and the procedures that are facing these climate fluctuations. And its negative impact on the net revenue of the sugar beet crop. The research has reached some important results for the period (2012-2021):
- Increasing the net revenue of the sugar beet crop, which amounted to about 3.8 thousand pounds.
- Small and greatest temperatures fluctuate during the cultivation, growth and harvesting of the study crop.
- Increased relative humidity during agriculture and growth periods (except for the harvesting period).
- The low temperature decrease 0.5: 1 °C  leads to an increase in the net return of the study crop of about 8.8%, 21.9%, respectively.
- The increase in the maximum temperature 0.5 °C  leads to an increase in a net sugar beet yield of about 0.11%, while increasing the maximum temperature of 1 °C  leads to a decrease in the net return of about 1.36%.
- The lack of relative humidity 10% leads to an increase in the net return of about 61%, and on the contrary, the increase in humidity 10% leads to a reduction in the net about 10%.
Therefore, it was necessary to choose the appropriate items for the sugar beet crop and determine the dates of agriculture in a manner consistent with climate changes within each governorate.
