the radial and concentric arterials and peripherial 
nucleation of industries. By and large, the present 
land use pattern in Benin City is "polymeric": partly 
responding to the sectorial process and partly to the 
forces of concentric formations. The sectorial forces 
include the social identification of people of the 
same status, while the concentric pattern is mainly 
a product of geographic inertial. And, the polynuclea- 
tion of outlying and peripheral commerce and industry 
is partly due to economic and accessibility forces 
(Ikhuoria, forthcoming, January 1987). 
3. The internal structure of Warri reflects admix 
ture nucleations of residential neighbourhoods based 
on ethnic, social and economic considerations in 
different parts of the city, agglomeration of comme 
rce and industry due to accessibility forces, well 
planned and highly developed middle class and high 
class residential estates. 
4. The indigenous cores of Lagos Island, Benin City 
and Warri exhibit serious indications of urban blight. 
5. The diversity of land use patterns manifested 
on the landscape can be inventorized and mapped from 
remotely sensed imagery and the data serve as posi 
tive explanations of urban spatial structure. 
6. In creating an effective environmental resource 
management and monitoring systems in third world cou 
ntries, the utilization of remote sensing (particu 
larly aerial photography) to acquire the necessary 
data should be encouraged.
