Abstract
This work examined effects of anthropogenic activities on vegetation changes in Guinea
savanna region of Edu Local Government Kwara State, Nigeria. There are various economic
activities going on in the region and these activities have significantly contributed to the changes
in the vegetation cover of the study area. Erdas Imagine 2015 was for computerizing NDVI, ArcMap
version10.5 for images extraction; mapping of study area and NDVI mapping; ArcMap 10.5 for the
conversion of the images (vector) to raster and excel for the calculation percentages and graphs.
Normalized Difference Vegetation Index (NDVI) were used as method for detecting any form of
changes in Edu local government open forest. NDVI result shows (-0.26) which indicates a decrease
in vegetation cover in the study area. The vegetation index Map of 1990, 2005-2018 also shows
that there is further decrease in vegetation (0.58) (0.48) in 1990 and 2005 respectively. NDVI
values of (0.35) indicated a decline in the vegetation of 2005 -2018(0.48) (0.35) respectively. The
patches of thick green colour of 1990, 2005 and 2018 images show continual decreased of forest
from 1990-2018.The shrubs continue to expand from 1990-2018.This means that, there is sharp
decline in the Forests cover between the intervals of another fifteen years. Tree planting campaign
should be undertaken through print and electronic media, public and private owned radio stations.
The campaign should educate recent flood events that ravaged the region.
Description

enormous pressure on the forest’s resources in
Nigeria, the desire to get foods, cloths and
shelters keep growing with the increase in
population and these trends is persistence. This
is not only through subsistence farming system
but also commercial Agriculture. Agricultural
practices have done a lot of damages to the
forest cover the world over.
