ABSTRACT: The main objectives of
this study were to detecting the land use and land cover change (LULC), using
remote sensing techniques, then identify the reasons for rangeland and tree
cover degradation in El Rawashda Forest, Gadarif State, Sudan. The study has
conducted field experiment developed on an area of 20 feddans that was affected
by deterioration in the forest and to assess the best method for rehabilitation
of the vegetation cover in the area of study. The experimental area was divided
into 5 blocks; each block consisted of 4 treatments: grass seeds and Talih
(Acacia seyal var. seyal); sowing seeds just before autumn, sowing seeds after
disc ploughing, sowing seeds using water harvesting technique and control (no
seeding). In the present study an attempt has been made to analyze and monitor
the LULC changes using multi‐temporal Landsat data
deterioration in the forest and to
assess the best method for restoration of the vegetation. In the present study,
an attempt has been made to analyze and monitor the LULC changes using multi‐temporal Landsat data for years
1984, 1994 and 2013. LULC grades in the classification scheme are: Trees, Mechanized Rain-fed Agriculture (MRA),
Grasses and Bare land. Individual classifications based on maximum likelihood
of algorithm were used and the results showed a significant that extensive
change of LULC patterns has occurred in all decades in the study area. The
results also show Trees class was decreased, while MRA, Grasses and Bare land
were increased. The seeding of the forage and Talih seeds after disc plowing
gave the best results compared to the other treatments, followed by forage and
Talih seed sowing under the water harvesting technique and broadcasting of
forage and Talih seeds and finally the control.
