Abstract: The study analyzed
changes in land use and land cover overtime in Port-Harcourt metropolis using
remote sensing techniques from 1984-2013.The Geo-referencing properties of 1984,
1999, 2003 and 2013 include; universal Transverse Mercator (UTM) projection, and
datum WGS 84, zone 32, ERDAS Imagine (2014).These were used for displaying
processing, enhancement, classification of the imageries and also used for the
delineation of the study area imagery. IDRIS SELVA was used for the development
of land use land cover classes. ArcGIS 10.1
was used in developing,
display and processing of the location maps. Total percentage change and total
rate of change for the entire trend after conversion are thus: Saltwater Wetland
23.44 %, to- 2.17, Freshwater Wetland
-26.44%to- 11.49 Fallow
land- 47.13%to- 5.41 Built-up Area 43.33% to 7.41Water bodies 43.36% to 3.06.
The study recommended that activities shrinking wetlands size should be
thoroughly put to check by the government and better efforts should be focused
on those activities that inspire wetland conservation.
