Africa still does not realise the potential and opportunity that science and innovation hold for its development and the time has come for the continent to be serious about investing more in research, development and innovation, International Relations and Cooperation Minister Naledi Pandor said on Wednesday. “It is from this continent that we must develop the response to HIV/Aids and new drugs against tuberculosis. It is also on this continent that we are building the largest radio telescope in the world, so we should wake up to the opportunities of science and innovation,” she noted during the Science and Technology Showcase at the 2019 South Africa Investment Conference.
