Siyanbola, W, Adesina F, Pelemo DA, Oketola F, Ojo L, Adegbulugbe AO.  2002.  Towards global climate change mitigation: Assessment of an afforestation option for Nigeria, 2002/03/01. 22:83-92. Abstract

This paper assesses the potential of an intensive afforestation program as a measure of reducing the atmospheric concentration of carbon in Nigeria. The results presented are based on the recently completed Nigerian Country Studies Program on Climate Change Mitigation. A comprehensive mitigation analysis process (COMAP) model was employed to carry out detailed cost/benefit evaluation of the mitigation option. The end-use based scenario adopted was considered the most appropriate strategy to sustainably implement the mitigation option in Nigeria.The analyses showed that the country could significantly reduce net carbon emission while at the same time meet all her essential domestic wood needs, if approximately 7.5×106 ha of wasteland could be committed to an afforestation program over the 40 year period of projection. The initial cost of establishing such forest plantations, taking cognisance of the opportunity cost of land averaged at about US$500/ha, or in carbon terms, a unit cost of about $13 per tonne of carbon. In terms of carbon flow, if all the end-product based plantations considered (i.e. fuelwood, poles, pulpwood, sawlogs and veneer) were fully established and maintained, it was estimated that by the year 2030, the total carbon stored in the afforested land would be about 638.0×106 t of carbon with an annual incremental rate of 16.0×106 t of carbon. Other economic indicators (i.e. net present value of benefits, present value of costs and benefit for reduced atmospheric carbon) when evaluated showed that the afforestation option could be economically viable even when the investment capital was discounted at rates ranging from 9 to 33 percent for different wood products. It should be noted, however that implementation of such a program would require huge sums of money and a high degree of commitment on the part of Federal, State and Local governments if the associated financial, social and environmental benefits were to be derived.

Research and development (R&D) is a significant component of quality higher education. This is quite understandable and appreciable because R&D, most especially in Science and Technology (S&T), has become the most enduring and effective means of improving sustainable economic growth, development and re-enforcing competitiveness in industries in a rapidly changing world. Universities are widely regarded not only as teaching establishments but also as organisations that create new knowledge and innovation through research. Many academics are of the opinion that doing research improves their teaching (Colbeck, 1998, 2002; Gamson, 1995; Stevans and Reingold, 2000; Robertson and Bond, 2001; Wenzel, 2001; Winkler, 1992a, b; Woolcock, 1997; Zamorski, 2002; in Begum, 2006). In recent times, universities often use evidence of research excellenceto employ or promote staff. The main claim of the teachers and administrators are that research activity can and does serve as an important mode of teaching and a valuable means of learning and thus research is a strong condition for teaching.R&D is one of the main thrusts of activities of western universities. The developed nations have clearly demonstrated that one of the most potent means of achieving developmental goals is effective building of capability in Research and Development. They have also demonstrated the relevance of effective collaboration to sustainable scientific and technological advancement (Boozeman and Lee, 2003). To corroborate this, Ehikhamenor (2003) opined that scientific productivity, in the form of intellectual contributions to the advancement of S&T, is a fundamental consideration in the scientific enterprise. A crucial requirement for
productivity and development in S&T is a system of communication among scientists and the dissemination of scientific information. Productive R&D is expected to lead to new product(s) development or improvement of existing product(s), new process development or improvement of existing process, patents, copyrights and publications. Scientific publication is a sign of good quality of invention and research outputs. Patents, copyrights, and funds from companies are signs that those inventions have market potentials (Carneiro, 2000; Werner and Souder, 1997; in Numprasertchai and Igel, 2005). Tangible R&D outcomes should promote the link between academia and the industry. However, many private and public organizations in Nigeria are skeptical about R&D outcomes from the universities and in many cases the needs of these organisations are not met. These invariably have further widened the gap between universities and industries (Oyebisi et al., 1996).
Many studies on research productivity and collaborations include an underlining assumption that collaborative activities increase research productivity (Duque et al., 2005). However, there is a dearth of information on the validity of this proposition in Nigeria. Are Nigerian researchers collaborating for R&D among themselves and with others outside their institutions? What factors inhibit collaboration activities of researchers? What influence do researchers’ collaborations have on their R&D productivity? These are some of the pertinent questions addressed in this study. For the survey, 457 copies of questionnaire were randomly distributed among lecturers. 274 of these were returned and found useful (60% response rate). The field respondents were from Faculties of Agriculture (30.8%), Science (38.8%) and Engineering/Technology (30.4%). In assessing R&D productivity of researchers we adopt the partial productivity approach. Researchers’ publications were used as output and the number of years spent to produce the publications as input (in this study 5 years, (2004 – 2008)). The normal count (of output), which is the most frequently used approach, is adopted. The outcome of the study indicated a positive relationship between R&D productivity and collaboration. This is in agreement with some previous studies on the subject of research productivity and collaboration (Lee and Bozeman, 2005; Landry et al., 1996; Harman, 1999; in Rijnsoever et al., 2008, Walsh and Maloney, 2003; in Duque et. al., (2005)

Medicinal plants have been used in healthcare since time immemorial. Studies have been carried out globally to verify their efficacy and some of the findings have led to the production of plant-based medicines. The global market value of medicinal plant products exceeds $100 billion per annum. This paper discusses the role, contributions and usefulness of medicinal plants in tackling the diseases of public health importance, with particular emphasis on the current strategic approaches to disease prevention. A comparison is drawn between the 'whole population' and 'high-risk' strategies. The usefulness of the common-factor approach as a method of engaging other health promoters in propagating the ideals of medicinal plants is highlighted. The place of medicinal plants in preventing common diseases is further examined under the five core principles of the Primary Health Care (PHC) approach. Medicinal plants play vital roles in disease prevention and their promotion and use fit into all existing prevention strategies. However, conscious efforts need to be made to properly identify, recognise and position medicinal plants in the design and implementation of these strategies. These approaches present interesting and emerging perspectives in the field of medicinal plants. Recommendations are proposed for strategising the future role and place for medicinal plants in disease prevention.
