1.6.6 Socio-economics activities
Port
Harcourt is the heart of Nigeria’s Oil industry with virtually all
major multi-national oil companies being represented there until
recently owing to security threats from Niger Delta militants and
Cultists. The economic activities of Port Harcourt include manufacturing
such as food processing, car assembly, manufacture of paper products,
paints, petroleum products refinery and road construction, metal works
and cement making, enamelware, bicycles, furniture, and soap making.
Services include legal services, hospitality, medical, Educational and
engineering services. Extractive industries also exist such as mining of
coal, tin and petroleum, oil and gas liquefaction. Also agricultural
and agro based businesses exist in the city some of which are logging
and timber processing, tobacco processing and cigarette making, plastic
moulding and the manufacture of rubber based products like tyres, bands
and tube and glass making. Imports are mainly automobiles, electronics,
textiles and processed food. Sometimes rice, millet and meat and other
agricultural produce are imported as well. Then numerous small scale
enterprises like consumer retailing, artisanship and transportation
businesses also thrive in the city. Various government organs such as
the Nigerian Ports Authority, NNPC and the customs play various
regulatory roles in the local economy. The main industrial area of the
city is Trans Amadi. Residential areas include Port Harcourt Township
known locally as "Town", G.R.A phases 1-5, Abuloma, Amadi-ama, Amadi
Flats, and Borokiri.
Crime rate in Port Harcourt Nigeria is one of
the highest. The worst cases so far have been crimes committed by
criminal gangs disguising their illegality as freedom struggles for the
marginalized locals of the oil rich Niger Delta Region. Other than these
and congestion, Port Harcourt Nigeria is largely a peaceful and
sociable city. With many recreational and fun spots, Port Harcourt can
boast of a number of 5 star hotels such as the Meridien Hotel,
Presidential Hotel among others. Also newly open entertainment centres
with cinemas, night clubs, bars and restaurants can be found in the
city.
1.7 Limitations of the Study
This research work was
not without some limitations. The major limitations of this study was
that the study area was very wide and so difficult to get all the
attributes for roads and buildings with available map not providing all
the names of the roads and rivers; and the usage of buildings.
These
limitations however were overcame by proper digitization of the
satellite imagery, giving code names to roads and rivers were the names
were not known and generalizing buildings.
