Objectives

Igbiloba O. Enoch (URP/08/4352)

1. Spatially map out the sub-urban area using remotely sensed data and GIS

techniques;

2. Identification of various land cover and land use classes in remotely sensed

data sources of the sub-urban;

3. Analyze the acquired remotely sensed imageries of the study area so as to

establish the rate and trend of growth of the sub-urban in relation to the

physical and demographic growth of the campus;

4. Calculation and quantification of the basic land use and cover data in the

sub-urban area in relation to the population growth of the university

campus from 1986, 2002 and to 2013;

RECOMMENDATIONS


This study have revealed the

decline in forest resources

in the suburban,

The built up area is increasing

with the institution’s

population , hence demand for

off campus accommodation

This study has shown the

increasing growth of the sub-

urban towards the Akure City

metropolis
