Assessment of changes of land use/land cover of a command areae in Nile delta, Egypt, using remote sensing and Geographic information system techniques [electronic resource]

Includes bibliographic reference

This study aimed to detect the changes of land use of Meet
Yazid commend area, in Kafr Al-Shikh and Al-Gharbia
governorates during the period from summer 2013 to winter
2015 using remote sensing and GIS techniques. In this study,
RapidEye images, dynamic GPS and IMAGINE objective feature
extraction module were used. The results showed an increase of
cultivated areas of rice from 30.06 % to 31.57 %, while wheat
increased in the year 2014 and 2015 from 27.3 % to 37.9 % of the
total area respectively. On the other hand, there was a decrease of
cultivated areas of maize and cotton in years 2013 and 2014 from
24.64 % to 23.29 % and from 15.26 % to 14.68 % of the total area,
respectively. Clover cultivated areas decreased in years 2014 and
2015 from 21.5 % to 18.5 % of the total area, respectively. The
changes of the crops in these areas may be due to the change in the
social and agricultural economics. The results also showed that the
rate of urban encroachment increased during the study periods
where results recorded increasing in urban areas from 13.64 % of
total areas in summer 2013 to 14.85 % of total area in winter 2015.
The study cleared that increasing in total cultivated area of crops
throughout the period from summer 2013 to winter 2015 except the
period summer 2014 where occurred decreasing in total cultivated
areas of crops for the previous sessions. The changes in cultivated
area was accompanied by changes in the areas of fish ponds in the
same period, which is due to transformation in the pattern of land
use from crop cultivation to aquaculture, in some areas. The results
also show the ability of RapidEye images of high differentiation for
land use classes as well as obtained results with high accuracy more
than 90 % for all studied seasons.
