Keywords:Land use/land cover, Change detection, Transition, Urban expansion.
The purpose of this research is to analyse the effect of Urban Expansion on Land Use/Cover Change in Dutse, Jigawa State, Nigeria. Landsat TM and ETM+ satellite imageries of 1986, 2000 and 2014 respectively, were used. 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 that increase in built-up area resulted to changes in other 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. 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 changes into built-up of about 4.5% from 1986-2014. 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.
