Abstract
This study identified land use/cover in Omotosho Forest Reserve, Ondo State, Nigeria,
and analysed changing pattern of land use/cover in the forest reserve. It also measured the extent
of forest loss to different land uses, and examined the drivers of land use change in the forest
reserve. These are with the view to determining the extent of forest degradation in the forest
reserve.
The study adopted descriptive survey research design and used primary and secondary
datasets. The primary data included the coordinates of selected features (settlements, rivers and
rocks) in the forest reserve, and these were obtained using a handheld Global Positioning System
(GPS). They also included the responses of 36 Key Informants (six purposively selected adults
(aged > 30 years) persons from six settlements around forest reserve). The secondary data were
Landsat ETM+ 2000, Landsat OLI 2010, Sentinel 2015 and Sentinel 2020 satellite images of the
study area. The satellite imageries were first processed and georeferenced using the coordinate
values of the selected features, before they were analysed using remote sensing and Geographical
Information Science procedures in ArcGIS (10.4 version). Derived values from the analysis were
analysed using frequency and percentage distribution techniques. Responses of the key
informants were analysed using content analysis.
The results showed that the identified dominant land use/cover in the study area were
dense forest (29,727 ha), shrubs (14,348 ha), farmland (13,462 ha), settlements (8,252 ha), open
spaces (3,014 ha) and water bodies (699 ha). Results also showed that while farmland increased
in area cover between the period of study (from 9,247 ha – 13,462 ha), areas covered by
settlements also increased (from 4,718 ha – 8,252 ha), open spaces increased in area covered
from (984 ha – 3,014 ha) and scrubs increased from 10,108 ha – 14,348 ha), amount of
