Land is a natural resource which is a scare commodity. It is
therefore important to classify land and
Land Use. The city of Port Harcourt has experienced a
lot of changes on Land Uses and Land Cover
which has had an impact on the spatial pattern of the
city. This study hopes to identify how the varying climatic changes and elements have affected the spatial
pattern of Port Harcourt and to ensure that there
is sustainable development. The methodology used was Geographic Information
Systems (GIS) and remote sensing which provided
a cost effective and accurate alternative to understanding landscape dynamics. Digital change detection techniques based
on multi-temporal and multi-spectral remotely
sensed data was also used. Objectives of the Study are to examine the spatial
pattern of Port Harcourt between the periods of
1984 –2014. To ascertain how climatic factors have affected the spatial pattern in Port Harcourt. To determine the present
state of Land Use and Land Cover in Port Harcourt
and how it has been affected by climatic elements. The result of the study
showed that there have been climatic deviations
in rainfall and temperature values and very obvious changes in the spatial pattern of Land Use and Land Cover between 1984 to
2014. The Built – Up area showed an increase
from 16.50% in 1984 to 51.38% in 2014. A lot of development has taken place using
up most of the Gallery Forest, Vegetation area
and the Water Bodies. Development of Built – Up area needs to be controlled so that all of the vegetation is not used up
because the city needs some vegetation to allow
the city breath.
