Abstract
The primary objective of this research is to provide todate
data on the extent changes in land use in East Delta of
Egypt and study the agriculture expansion over non arable lands
versus urbanization over arable lands.
15 soil profiles were dug and soil samples were collected
in 2 major areas. 10 in old agricultural area (collected as surface
layers) and 5 in new reclaimed area (collected as complete
profile). The soil profiles were described and soil samples were
analyzed. Maps of urban areas were prepared.
The soils were mainly Nile alluvium. CaC03 ranged from
0.39 to 3.70%. Gypsum ranged form 0.19 to 0.82%. Organic
matter ranged from 0.59 to 1.74% and high contents were in the
top layers. EC (of paste-extract) ranged from 0.75 to 8.48 dS/m.
The current study data was compared with data collected
on the same area in 60s by the Soil Survey Department of the
Ministry of Agriculture (SWRI, 60s). Multitempral images were
processed using topographic maps. Comparative assessment of
12 urban expansion area during the 48 years (from 1952 to 2000)
show the nature of this expansion up to year 2000 and its
direction in the studied areas. The study concern maps in 1952,
and recent Landsat TM images in 1989, 1995 and 2000.
Manipulation and processing were done using Imagine Software
program version 8.4. There were considerable urban expansion
between 1952 and 2000. In 1952 the urban area of selected
settlements (little and medium size towns) varied between 27 fed
(in El-Tell El-Kebir) to 2009 fed (in Ismailia). In 2000 urban
area increased, ranging from 228 fed (in El-Tell El-Kebir) to as
high as 7286 fed (in Ismailia). The magnitude of increase in
2000 compared with 1952 was 2.6 to as high as 11.1 folds.
Urban area for each urban location in 1952 and 2000 (area in
fedans and times of increase since 1952)were as follows:

The areas in the new reclamation desert land had
categories obtained by supervised classification in year 2000.
These categories were: (1) densely cultivated land ”150948 fed”,
(2) sparsely cultivated land ”43149 fed”, (3) bare land ”110386
fed”, and (4) water bodies and submerged land ”27637 fed”.
The changes in land use in a pilot area were designated as
area loss to urbanization within the old agricultural Delta land to
about 22400 fed and the area gain within the new reclamation
desert land to about 63700 fed. Thus the net result is on the side
of area-gain, a gain of about 41300 fed. However, the quality of
lost land exceeds and is far superior than that of the gained land
from the agricultural view point.
