Sand dunes and border roads in northwest Nasiriyah - Al-Kataia area as an example

Abstract

Climate change is a disturbance in the Earth's climate with an increase in the temperature of the gasosphere, a change in natural phenomena, a continuous deterioration of vegetation and environmental diversity, and the emergence of new climate patterns. Which affects the regularity of the earth’s temperature and the succession and balance of phenomena. As a result of these changes, we find that the Al-Kati’ah area, located northwest of Al-Batha district, was completely affected in such conditions, which led to the spread of the phenomenon of desertification. It is located astronomically between two latitudes (23-31 AH - 47-30 AH) to the north. And two arcs of length (40-45 AH - 10-46 AH) to the east. Administratively, it is located in the northwest of Al-Bathaa district and is administratively affiliated with Al-Nasiriyah District, one of the districts of Dhi Qar Governorate. It is bordered to the east by the Al-Gharraf River, to the north it is bordered by Wasit Governorate, and to the west it is bordered by Al-Khader District and South is the Euphrates River, and its area is estimated at (789 km2), which represents (6.11%) of the area of Dhi Qar Governorate, which is (12,900) km2. Which led to the encroachment of sand dunes on the international road, in addition to its impact on agricultural lands, human health, and vital facilities.
