Qaliubiya governorate is located in the South East of Delta,east of the Damietta branch,stretching astronomically between latitudes 20 ”6’30 °, 26” 36 ’30 ° N,and longitudes 0 ”3’31 °, 20” 35 ’31 ° to the east, it is bounded to the north by the governorates of Dakahlia and Gharbia , and to the south by the of Cairo and Giza, and to the east by the governorate of Sharkia and to the West by Menoufia Governorate, and has an area of 1001.09 km 2 approximately. The study aims to monitor the change in land use patterns including: agricultural,residential,industrial, commercial and service, during the period from 1986 to
2012, and also the work of outlook during 2027 and 2050, and through the study, it proved the presence of some of the problems
caused by the misuse of the land.
Although Qaliubiya is one of the agricultural governorates and the agricultural use in it ranked first among other uses, but the
area has seen a clear decline during the study period, as it fell from 787.61 km 2 in 1968 to 688.19 km 2 in 2012, and is expected to reach the decline in 2027 to 645.37 km 2 and in 2050 to 589.33 km 2, and the main reason for the decline is the ongoing urban encroachment on agricultural land.
There is a change in the area of residential use, but in the increase, the area increased from 69.18 km 2 in 1986 to 131.38 km 2 in 2012 to, and is expected to continue to increase until it
reaches 184.75 km 2 in 2027, and 341.56 km 2 in 2050 to, because the main reason for this is the continuous increase in the
number of population, which requires the provision of spaces for housing, even if at the expense of other uses, including agricultural use. The area of industrial use and trade in 1986 reached about 29.69 km 2, and increased in 2012 to 52.22 km 2, and is expected to continue to increase in 2027 to 71.58 km 2, and also to 126.18
km 2 in 2050, and similarly in the case of the use of service,which recorded in 1986,about 9.42 km 2, and in 2012 about 22.29
km 2, and the area is expected to increase in 2027 to 34.66 km 2
and in 2050, about 77.23 km 2, is the use of the service, and continued for the rest of uses,because its increases depends on the increase of the other uses,and vice versa.
