Abstract
The work used geospatial techniques (Geographic Information System, and Remote Sensing)
to assess Land Use/Cover in River Ominla Catchment. Digital Elevation Model of the area
from Shuttle Radar Thematic Mapper (SRTM) wasused to delineate the study area. The
multi-date satellite imageries, Landsat TM 1986, Enhanced TM + of 2000 and 2015 were
subjected to supervised classification to detect spatial temporal change. Results showed
significant change since 1986 to 2015. Built-up increased by 3.70% in 1986-2000 and 6.32% in
2000-2015. Undisturbed forest decreased by 32.08% in 1986-2000 and 19.26% in 2000-2015.
Shrub land increased by 3.30% in 1986-2000 and 9.25% in 2000-2015. Disturbed forest
increased by 25.54% in 1986-2000 and decreased 2.05% in 2000-2015. Bare surface reduced
by 1.13% in 1986-2000 and increased 2.91% in 2000-2015. Cultivation increased by 67% in
1986-2000 and 2.84% in 2000-2015.Built-up was negatively correlated with undisturbed
vegetation with r = -0.957 and p = 0.095; positively correlation with shrub land with r =
0.993 and p = 0.037; positively correlated with disturbed vegetation with r = 0.735 and p =
0.237;positivelycorrelated with cultivation with r = 0.98 and p = 0.062 all at α = 0.05

respectively. Therefore, the study concluded that there was significant change in River
Ominla catchment and that this requires urgent attention.

Introduction
Land use/cover dynamic for centuries has
been a determinant of river catchment
condition.
Loss of indigenous forests and their
subsequent conversion to agricultural use
in East Africa, for example, is one of the
major threats to surface water quality
(FAO, 2010).Temporal mapping develops
a historical perspective of urban
development by combining a variety of
datasources into an integrated, multi-scale,
and multi-resolution database (Nasreen,
2014). This is technique is usually adapted
to change as a result of natural and
artificial on phenomena in question.
Spatial temporal mapping has variety of
applications to include vegetation, soil,
and population land use/cover change
detection. This could have taken its origin
from manual land survey as far back as
time immemorial. There is now paradigm
shift from bare-footed approach method of
spatio-temporal mapping since the
invention of space satellites. Oyeniyi,
(2000) opined, the traditional method of
presenting geographic information has
proved to be quite slowTherefore, the
adoption of remotesensing and geographic
information system (GIS) technique is
considered indispensable in furthering our
understanding of the spatial and temporal
pattern of urban expansion (Aguda et at.
2011).This has been applied by many
authors.Remote sensing data and GIS help
in analyzing the pattern, growth and extent
of urban sprawl pattern (Sudhiraet al
2004).GIS and remote sensing (RS) were
used to compile and create database that
provided a visual and historical

Study Area
Ore is one of the towns in Odigbo Local
Government Area, Ondo State,
Southwestern Nigerian (see fig 1.). Ore
Township is headquartering of Odigbo
Local Government Area. It lies between
Lat. 6o
42’ and 6° 56’ North and Long.
4
o
49’ and 4o
56’ East. According to Aguda
et al. (2011), it was found that Ore
Township occupied an area of 1.2 km2
in
1964, expanded to 11.3 km2
in 1986 and
13.2 km2
in 2002 respectively. He also
predicted that it would expand to 55.33
km2
by 2027. The whole landscape is
located in tropical rain forest vegetation
and form part of the catchment of River
Ominla. It is a nodal settlement that covers
the region where Lagos –Benin and Akure- Okitipupa roads intercept.

The river takes its source from the western highland in Nigeria. Specifically, it sourced from
Igurowo settlement and its tributaries are from many locations within the catchment. And it
flows southward traversing many settlements like Ashewele, Odigbo, Ore Township (and
