    Academia-industry interactions in Nigeria pharmaceutical innovation system
    (Elsevier, 2012-01-01) Siyanbola, W. O.; Oladipo, O. G.; Oyewole, A. A.; Famurewa, Akindele J.; Ogundari, I. O.
    This study examined the types, nature and intensity of academia-industry interactions in Nigeria’s pharmaceutical innovation system. Eight (8) top-ranked universities offering Pharmacy as a course of study, 2 Pharmaceutical Research Institutes and 25 pharmaceutical firms were sampled for the study. Interactions are predominantly in the form of knowledge flow and consultancy, staff exchange/fellowship programmes as well as sponsored workshop participations. Intensity of interactions is limited as only 20% of pharmaceutical researchers from Universities and 7% from Research Institutes had strong interactions with Pharmaceutical firms, while only 4 firms have strong interactions with the researchers.

    Analysis of Sustainable Cassava Biofuel Production in Nigeria
    (SAGE Publications, 2012-06) Ogundari, I. O.; Momodu, A. S.; Famurewa, Akindele J.; Akarakiri, J. B.; Siyanbola, W. O.
    Nigeria's biofuels policy advocates the adoption of cassava as feedstock for a 10%-biofuel substitution option in Nigerian transport fuel demand. This policy option is expected to address energy security and environmental consequences of using fossil fuels as the sole source of transport energy in the country. This paper appraised the technological and economic factors necessary for achieving Nigeria's cassava-based biofuel initiative at different substitution levels of 5, 10, and 15% by the Year 2020. A multi-stage energy forecasting and project analysis framework adapted from Coate's structure for technology assessment, as well as engineering economy methodology was used for the study. Technological analysis entailed determining petrol consumption projection, R&D capability, input feedstock requirements, environmental considerations and land requirement for feedstock crop production while engineering economy analysis evaluated the economic viability of the project. The results showed that petrol consumption in Nigeria and bioethanol substitution requirements were in the range of 18,285.7 – 19,142.84 thousand tons and 914.28 (5% low demand) – 2871.43 (15% high demand) thousand tons, respectively by 2020. Cassava feedstock and landmass requirements for bioethanol production were in the range of 4.64 – 14.53 million tons and 4.08 – 12.80 thousand sq. km, respectively while carbon dioxide savings were between 1.87 – 5.89 million tons by 2020. The recovery price for cassava bioethanol was estimated to be US$ 0.74/litre . Petrol being subsidised presently is harmful to the environment though it ‘oils’ the economy. Nigeria currently subsidizes petroleum products to the tune of 28% of 2011 budget. The government plans to remove this by 2012. Thus we conclude that weighing both economic and environmental benefits of bioethanol substitution in petrol consumption in Nigeria, the study showed that bioethanol production from cassava feedstock would be both technically and economically viable, provided subsidy, which depends on political will on the side of the government, is introduced for the first ten years of its implementation.

    Risk mitigation strategies and policy implications for carbon dioxide (CO 2) emission in organically-amended soils in Nigeria
    (Academic Journals, 2010) Gbemisola, O. O.; Akin, O.; Aladesanmi, O. T.; Maruf, S.; Famurewa, Akindele J.; Siyanbola, W. O.
    Global food security has been a challenge, especially in Africa. This has attracted the adoption of strategies to improve soil productivity and crop yield. One of such strategies is the use of solid wastes as soil organic matter amendments. An investigation of the effects of soil amendment using poultry manure, sawdust and their mixtures on carbon dioxide (CO 2) emission, maize (Zea mays L.) growth and dry matter yield were assessed under laboratory and greenhouse conditions. Top soil obtained from unfertilized plots at the Obafemi Awolowo University Teaching and Research farm, Ile-Ife, Nigeria was used for the experiments. The organic amendments were added at the rate of 10 g/kg, treatments were in triplicates and treatment means were separated using Duncan’s Multiple Range Test at 95% level of significance. Results obtained revealed that CO 2 emission decreased while maize heights and dry matter yields significantly (P> 0.05) increased with increasing ratios of poultry manure in the poultry manure-sawdust mixtures. The CO 2 emission from poultry manure amended soil was about 61% that from sawdust amended soil while the mean height and dry matter yield in sawdust-amended soils were 84% and 52% respectively those obtained in poultry manure amended soil. This paper concludes that it is essential to design and implement policies that will guide and encourage the use of organic amendments at ratios that can enhance crop yield and mitigate CO 2 emission to the environment.

    Strategic issues in jatropha biofuel enterprise development in Nigeria
    (IEEE, 2010-07-18) Ogundari, I. O.; Oladipo, O. G.; Famurewa, Akindele J.; Ali, G. A.; Aladesanmi, O. T.; Ogunkanmbi, D. A.; Siyanbola, W. O.
    In Nigeria today, fossil fuels constitute the major source of energy for the economy with consumption costs in excess of N 654 billion for petrol, N 303.2 billion for diesel and N 194 billion for Kerosene. The global debate on Climate Change/CO 2 emissions and domestic concerns on economic, environmental and energy security implications have necessitated alterative energy options and created opportunities for sustainable biofuel enterprise in Nigeria. Jatropha curcas (known as Lapalapa in Yoruba-speaking parts of Nigeria) is an uncultivated non-food wild-species plant with great potential for bioenergy development in the country. The seeds are resistant to a high degree of aridity and contain 27-40% oil that can be processed to produce a high-quality biodiesel fuel, usable in a standard diesel engine. With estimated diesel demands in Nigeria being 3600-4200 thousand metric tonnes by 2020, there is an expansive opportunity for jatropha biofuel enterprise in the country. This study examines the strategic issues (technological, economic, environmental, and socio-cultural) governing its development and proposes policy recommendations for its successful exploitation.
