Abstract
The purpose of this research is to analyse Land Use/Cover Changes in Dutse, Jigawa
State, Nigeria. The following objectives of the study were achieved, which are to;
establish the extent of land use/land cover coverage in the area in 1986, 2000 and 2014,
determine the rate and magnitude of land use/land cover changes in the area between
1986-2000, 2000-2014 and 1986-2014, and analyze the extent to which urban growth
influences land use/land cover changes in the area. Landsat TM and ETM+ satellite
imageries of 1986, 2000 and 2014 were used respectively. The imageries were processed
using ERDAS IMAGINE 9.2 software. A supervised classification approach using
maximum likelihood classifier and Transition Change Analysis were carried out using
IDRISSI 17.0 Selva Edition version. Results from the analysis revealed changes in land
use/cover categories between 1986 and 2014. Built up area was 20.4% in 1986 and
increased to 28.4% in 2000. Further increase was witnessed in built up area to about
38.2% in 2014. Cultivated land was 29.0% in 1986 and to about 31.0% in 2000, but a
decrease was observed to about 26.2% in 2014. It further revealed that bare surfaces was
23.3% in 1986 and decreased to about 18.8% in 2000. A slight increase in bare surfaces
was witnessed to about 20.0% in 2014. While other land use land cover categories
decreased or slightly increased over the study period. The most dramatic increase
experienced in built-up area is shown from 2000 to 2014. The results further revealed
that about 7.2% bare surfaces changed into built-up from 1986-2014. About 14.8% of
cultivated land changed into built-up from 1986-2014. Vegetation witnessed a
remarkable changed into built-up of about 4.5% from 1986-2014. It was concluded from
the study that there are various transformations in land use land cover of the area during
the study period. There is need for Jigawa State Government to equip the planning
authorities and other ministries involved in decision making with adequate spatial data
to ensure broad based decisions. Land use suitability analysis of the study area is also
recommended.
