Studies have shown that there are still growing concerns
about global population growth and the direction of the growth. Latest
population figures show that India has overtaken China presently as the most
populated country in the world. Malthus's theory of population growth even
though food production is becoming true in all aspects of human existence. The
suggested measures of Malthus's critics – new lands, international trade, and
industrialization are among the attractions of the new population direction –
the urban centers with massive accommodation pressure and subsequently
unplanned urban growth especially in developing countries. The study aimed at
carrying out geostatistical and geotechnical analyses of the terrain of Onitsha
Metropolis and its environs in Anambra State, Southeastern Nigeria and to
determine if the terrain can support the growth and expansion of the city
occasioned by the influx of people in recent years. The study used both primary
and secondary data. The primary data comprises physical observation,
measurements, soil sample extraction, and photographs. The secondary data
include satellite images from USGS - SRTM for image analysis of the geology,
and geomorphology of the area. The soil results for the geotechnical parameters
were analyzed using multiple linear regression analysis in Statistical Package
for the Social Sciences (SPSS) version 25.0 and Microsoft Excel, 2007. The
study identified areas of strong and weak geology and concluded that Onitsha
Metropolis requires executable plans for the Metropolis to attain the status of
a sustainable city.
