Investigation of the effects of dust storms caused by wind speed on the migration of rural population in the Sistan region

Abstract

Migration is a form of geographical or spatial mobility of a population that takes place between two geographical units. Research shows that environmental hazards such as wind speed, drought, and floods affect regional migration. The average annual wind speed in the Sistan region shows that from 1989 to the end of 2018, the wind speed increased by approximately 4.7 meters per second. The results of the data prediction showed that wind speed has a significant effect on rural population migration in the Sistan region. According to the census of 1335, the rural population increased from 92% to 56% in 1395, The calculation of the coefficient of determination shows that 85% of the decrease in rural population was related to wind speed and its results، Predicted values show that from 1398 the rural population will reach 55.39%, in 1399 to 54.88% and in 1400 and 1401 to 54.32% and 53.22%, respectively. Also, during the predicted years, i.e. from 1398 to 1401, 96% of the cause of rural migration was related to wind speed and its destructive effects, and 4% of it was related to other migration factors, the output shows that the coefficient of variable t statistic is equal to 2.507 in the positive model. This indicates that with increasing wind speed, rural migration also increases, which indicates the criticality of the region. Therefore, in the coming years, we have to wait for the evacuation of a larger percentage of the rural population in the Sistan region, and to solve this problem, control measures must be taken regarding the consequences of wind speeds and population stabilization.
