    International trade flow analysis using the gravity model - The Nigerian conondrum
    (MNK Publications, 2014) Onyemachi, Chinedum; Igboanusi, Chinemerem C.; Ezenwa, Anthony Ekene
    he work surveyed several international trade flow models applied to transportation and spatial interaction analysis. The connectivity between international trade flow, port development and hinterland acquisition were analyzed based on evolving market demands.The relevance of the gravity model both to the international trade and port hinterland analysis were identified. Methods for the estimation of trade flows using natural logarithms applied to the gravity model were developed. Furthermore, the work assessed the rising influence of both hub and dry ports in the world of international trade. While the later is situated in the hinterland, the former is situated at few major world ports. The relevance of the gravity model in determining the location of these port types was emphasized. The strategic roles of rising hub ports to world trade were also discussed. Relevant data were picked from the Nigerian Import and Export environment.

    Sustainable transport development options for Nigerian lakes
    (Ijournals, 2014) Onyemechi, Chinedum; Igboanusi, Chinemerem C.; Ezenwa, Anthony Ekene
    The work assessed development options in general and transport development options in particular, open to governments and states surrounding lakes. The methodology applied in the study includes random sampling through interviews of major companies in the region. For lakes situated in a desert environment the sustainable development pathway would be the avoidance and prevention of desertification through policies that favour lake expansivity. Processes that favour the expansivity of lake volume through dredging and channeling of rivers to the lake environment should be sought. The work suggested that installation of boundaries or moles to prevent building of sand dunes by lake boundaries be applied where possible. States utilizing such lakes should develop sustainable development policies to be applied in the process of utilizing the marine resources existing in the lakes. In the area ofrenewable resources like fishes, the commodity should be designed to be harvested to an optimum sustainable level. For non-renewable resources, like under water minerals the number of contractors accepted into the region should be limited to an optimum sustainable level approved by the states concerned. Other lakes not suffering from desertification as well as all lakes should be made to adopt the new environment standards of the oceans that emphasize prevention of oil spills such as MARPOL 73/78 (International Convention on Marine Pollution Prevention from Ships 1973 and the protocol thereto 1978) etc. Furthermore, the renewable energy resources of the lakes where it is made open to interested firms should be made to be tapped in a sustainable manner. Major Nigerian lakes such as the Oguta lake of Nigeria, Lake Chad situated between Nigeria, Niger and Cameron were made the major focus of this study. Sustainable transportation strategies necessary for the future development of these lakes were identified and recommended.
