BECOMMENOATIO~: The Yemen Arab Republ lc real !zed the crucial Importance of science end technology and Its role In national progress. Much effort Is directed by several of the concerned governmental Institutions In applying science and technology In development programs that are currently underway. However. more effort Is required In this direction to bridge the gap created during the pre-revolutions regime. Solution or el lmlnatlon of the aforemen­ tioned constraints Is Indispensable tor science and technology advancement and appl !cation to national development. The estab­ lishment of a National Centre for Science and Technology in the Yemen Arab Republic with Its goals mentioned In the proposal presented by the President of Sana1a University to UNESCO In 1980 certainly will Influence the promotion of scientific and techno­ logical development programs In the country. Establ lshment of this centre may lead to subsequent creation of a policy-making body responsible for promoting scientific and technological researches In various fields In the Yemen Arab Republic. Obviously, International and regional cooperation In sclentltlc and technological Issues Is strongly recommended. 24 REFERENCES (1) NATIONAL PAPER OF THE YEMEN ARAB REPUBLIC E/ECWA/NR/CONF. 2/CP.7.
