Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin
Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin

Land use land cover change (LULCC) is the result of
the long time process of natural and anthropogenic activities that has
been practiced on the land. GIS and remote sensing are the best tools
that support to generate the relevant land use/cover change in the
basin. This study was conducted in the Akaki River basin to detect land
use land cover changes within the 30 years period (1985-2015) by using
landsat imagery data acquired from the GCF. Supervised maximum
likelihood algorithm classification were deployed to classify land
use/cover into four prominent land use groups and data’s were processed
by using ERDAS imagine 2014 and ArcGIS10.1 software. In the basin
dominant LULC was agricultural land use which accounts around 56.28% and
the second largest is built-up area by 31.51% and the rest,
forest(11.9%) and water body(0.31%) coverage were takes third and fourth
position(as 2015 data). The rapid expansion of Addis Ababa city
consumes more fertile land near to the city. According to the projected
LULCC for 2030 the proportion of agricultural and built-up area near to
each other, i.e., agricultural land reduced to 42.33% and urban or
built-up area increased to 41.63%. One good thing observed in the basin
was an increment of the forest land in between 2011 and 2015 by 23.85%
whereas in between 1985 and 2015 the annual rate of change was by 4.2.
This may be due to the implementation of green-economy building strategy
of the government and other stakeholders to rehabilitate the degraded
lands in order to achieve MDG and SDG goals. Urbanization,
industrialization, commercial center enlargement and population
explosion in the main city Addis Ababa grabs more fertile and productive
lands which supports more semi-urban communities. Hence, the government
should consider the dramatic and drastic horizontal expansion of the
urbanization which resulted due to lack of appropriate master plan for
the city and towns in the basin to protect the loss agricultural
productive lands.
