ABSTRACT
Nigeria, which is more than three times the geographical size of Britain, has been described as “the giant of Africa” (Fagbadebo, 2007). The country has a population of approximately 165 million people, representing about a quarter of the total African population (Nations of the World, 2014). It is bordered to the west by Benin, to the north by Niger, to the northeast by Chad, to the east by Cameroon, and to the south by the Atlantic Ocean. The main rivers, the Niger and Benue, merge in the centre of the country, dividing it into three major regions of north, south, and east. The north consists of dry savannah, the south of jungle with mangrove swamps nearer the coast, and the east of a plateau leading into the country's only major mountain range along the Cameroon border.
