text: Research Council of Nigeria CMRCN), the Industrial Research Coun­ cil of Nigeria CIRCN> and the Natural Sciences Research Council of Nigeria CNSRCN>. After operating the 3-tler system for about six years, the entire machinery had to be restructured into a 2-tler system •. Therefore In 1977, a National Science and Technology Development Agency (NSTDA> was establ lshed to take over the functions hitherto performed by the NCST and the sectoral Research Councils. By that arrangement, the NSTDA had to combine both the advisory and executive as wei I as the sectoral research coordination functions of the defunct bodies. AI I the Research Institutes (22 In number) then came under the direct supervision of the NSTDA <Annex 1). REVIEW OF CURRENT DEVELOPMENT OF SCIENCE AND TECHNOLOGY IN NIGERIA In apparent recognition of the Importance of science and technology and the role they can play In the development of the economy, the NSTDA was transformed In 1979, Into a Ministry with similar responslblltles and authority to formulate science and technology pol lcles: direct, coordinate and monitor the Implemen­ tation of science and technology activities. Thse S&T activities however Include basic and appl led research, technological Innova­ tion and discoveries. scientific and technology services, and scientific/technical manpower training and development. Currentlyc these activities are performed by the following establ lshments: I) Public-funded research Institutes and centres II) Universities, polytechnics and other tertiary educational Institutions Ill) Scientific and professional societies lv) Manufacturing and services Industries; and 192 v) Technical/engineering design and consulting organizations. The Research Institutes and Centres undertake research In specific areas of agriculture (Including fisheries. livestock and forestry) processing of local raw materials for Industrial isatlon, medicine, etc., and the existing univtrlfTits concentrate on basic discipline-oriented research to facll ITttt the production of scientific manpower in order to tnhtnee Nigeria's capability to fully use science in her developllltnt.
