Abstract
This study examined the land use and land cover (LULC) changes in Karu Local Government
Area of Nasarawa State. Landsat data of 2000, 2005, 2010 and 2015 were utilized for this
study. Theimage classification of the study area was conducted using Maximum Likelihood
Classification and five (5) LULC classes were identified. In addition, land use and land cover
change matrix and the annual rate of land use and land cover for the study periods were
calculated. The results of the LULC classification revealed that built up increased from
928.7Ha in 2000 to 4098.8Ha in 2015 while vegetation decreased from 179187.7Ha in 2000
to 144764.8Ha in 2015. The LULC change matrix revealed that from 2000to 2015 about
161287.8Ha (61.2%) of the study area remained unchanged. From 2000 to 2015 built up was
growing at an annual rate of 22.8% while vegetation decreasing at an annual rate of 1.3%.
Therefore,NasarawaUbarn Development Board and other agencies responsible for the land
use planning of the LGA should also stand up to their responsibilities to ensure proper
sustainable use of the land.
