  • Chapter One Introduction
    CHAPTER ONE INTRODUCTION 1.1 Project Overview The lubricant sub-sector of the downstream industry is one with so many potential that is capable of being a major source of revenue earner for the country, and has grown over the years with increase in the number of second hand passenger and commercial vehicles in the country calling for more frequent lubricant changes. Though Nigeria has an installed lubricant capacity of 600, 000 metric tonnes the current demand is 700 million litres which is about 1% of global demand. The lubricants market is driven by various steps being taken by government such as initiatives to increase the ease of doing business to boost manufacturing sector activities and the Nigeria Economic Recovery and Growth Plan (ERGP) to emphasize investment in infrastructure. With the increase of import duty on finished lubricants to 30% and the recent 7.5 percent VAT on finished lubes in the country, the sectors have been opened up for further investment and the proposed project considered in this study is set to explore the given opportunity. Though there are presently 34 lube blending plants in Nigeria, only two of these (5.9%) are located in the south- south region of the country (DPR, 2020). This proposed lubricating oil blending plant project by Eraskon Nigeria Ltd is thus a private effort to support the government of Nigeria on how local production of lubricant can be increased to boost its domestic availability especially in the south-south region of the country. 1.2 Project Proponent Eraskon Nigeria Limited is a lubricant oil manufacturing company incorporated in Nigeria by the Corporate Affairs Commission (CAC) with RC No.

Received: 27 December 2013; in revised form: 13 May 2014 / Accepted: 30 May 2014 / Published: 10 June 2014 Abstract: Two genetically improved tilapia strains (GIFT and Akosombo) have been created with Oreochromis niloticus (Nile tilapia), which is native to Africa. In particular, GIFT has been shown to be significantly superior to local African tilapia strains in terms of growth rate. While development economists see the potential for food security and poverty reduction in Africa from culture of these new strains of tilapia, conservationists are wary of potential ecological and genetic impacts on receiving ecosystems and native stocks of tilapia. This study reviews the history of the GIFT technology, and identifies potential environmental and genetic risks of improved and farmed strains and tilapia in general. We also estimate the potential economic gains from the introduction of genetically improved strains in Africa, using Ghana as a case country.

N. Kenge*, M.S. Abdullahi and K. A.

Fish with scale and fins are equipped with digestive system that prevents the absorption of poisons and toxins into their flesh from the waters they come from. Collagen derived from fish scales could be used to heal wounds and for various biomedical applications. If you would like to live a healthy vibrant life, at least consider replacing some of those red meat meals, with some delicious fish. Reduce or eliminate shellfish from your diet and be sure that your fish has scales and fins. Heterotis (Heterotis niloticus) is one of the indigenous fishes with fins and scales. Its ability to survive in deoxygenated waters together with its great growth rate makes it a candidate for aquaculture.

    Governance of Oil and Gas Sector in Nigeria: Implications for Biodiversity and Ecosystem Services in the Niger Delta Region A Thesis Submitted for the Degree of Doctor of Philosophy Felix Olufemi Ogele Faculty of Humanities and Social Sciences School of Architecture, Planning and Landscape December 2016 i Dedication To the Almighty God, the only Impartial Potentiate that commenced, sponsored, supported, and perfected everything regarding the PhD programme. He alone is the Unchangeable Changer that transforms nobody to somebody. To my wife, My Only Queen (MOQ) as she is fondly called, Oluwayinka that gave me the best children in the whole world in the persons of Yomadeoluwa, Yomolaoluwa and Yosoreoluwa that came shortly after the commencement of this research. To the memory of my late father, Pa Shadrach Elaboma Ogele and my beloved mother, Mrs. Marian Abiodun Ogele for given me the privilege to discover the mysteries of books and taught me to work while it is day, for night comes when no man can work. To the unprotected people in the coastal communities of the Niger Delta Region who for no cause of their own continue to suffer and bear the impacts of oil and gas activities in Nigeria. ii Abstract Given the persistence of environmental problems that characterise the oil producing communities (OPC) of Nigeria, often referred to as the Niger Delta region (NDR), this thesis examines the implication of the governance of oil and gas sector on the biodiversity and ecosystem services (BES) in the region. The NDR is a coastal area that is most endowed in terms of BES and hosts exploration and production of oil and gas activities.
