CHINA’S OUTWARD INFRASTRUCTURE INVESTMENT IN AFRICA: A CASE STUDY OF NIGERIA’S RAILWAY CONSTRUCTION

Scholars and policymakers continue to debate the ramifications of Chinese foreign direct investment (FDI) and infrastructure development in Africa. Some argue that China’s activities in Africa create mutual economic opportunities, while others postulate that Chinese presence on the continent simply advances Chinese Communist Party (CCP) interests. More granular research into specific countries is crucial to better assess this debate. Using a qualitative methodology, this thesis examines the financing and construction of Nigeria’s railways by Chinese companies in the 21st century. More broadly, it evaluates the regional context of Sino-African economic cooperation on infrastructure development. Through a close analysis of press and official reports as well as a review of scholarly work, this study establishes the ways, means, and consequences of China’s investment in Africa. Chinese FDIs have helped to strengthen infrastructure, power generation, and resource extraction industries in many African countries, though not without costs such as huge debt burdens and disadvantageous trade imbalances. This study documents that Chinese financing and construction of Nigeria’s railway system has generated local revenue and employment and has facilitated technology transfer in the country, but the engagement benefits China even more because it expands the CCP’s economic influence and reinforces the Sino-Nigerian political connection.Commander, Nigerian NavyApproved for public release.

Graded level inclusion of melon shell in the diet of hybrid catfish (Heteroclarias) as energy source

Utilization of agricultural waste- melon shell by hybrid catfish (heteroclarias) 3.92 ~c 0.05g was investigated in this research. Five isonitrogenous diets containing 40% crude protein with inclusion levels of melon shell meal (MSM) at 0%,25%,50%, 75% and 100% in replacement of maize meal was fed to heteroclarias species for 56.days. The results indicated significant differences (P<0.05) in the growth parameters and body compositions. Diet containing 50% melon shell meal gave a significantly high mean weight gain, specific growth rate, protein efficiency ratio, apparent protein utilization and low feed conversion ratio respectively. The experiment supported the inclusion of melon shell meal up to 50% without detrimental effects on the growth of the fish

Development of 2.14 M one sheet canoe (SAMPAN) for pond activities

A 2.14 M length overall (LOA) flat bottom modern canoe (Sampan), was designed and constructed using locally available materials. The canoe features include easy construction, portability, least cost, light weight, shallow draft, and easy maneuverability. The light displacement (weight empty) was 25kg, which was less than local canoe of same size. When placed on water a draft of 5.5cm. The capacity of the canoe was 200kg, and the total production cost of N10, 000.00, ($67) which was not beyond the reach of an average fisher folks, or any fish farmer. The canoe was easily maneuvered when propelled by paddling as it floated at a shallow draft; this makes the canoe adequate for use on shallow water bodies such as ponds and reservoirs. The craft, because of its easy maneuverability, can also be used on shallow water bodies for recreational activities such as, sport fishing and canoeing
