In East and Central Africa considerable investment in physical capital is now being made. This must be matched by investment in human capital, if the full benefit is to be gained. Professor John Lewis, of the University of London, stressed ‘The Place of Adult Education in Education Development Planning’ in his contribution to this conference.

But at present the effort to educate adults, such as it is, is spread over many agencies. For significant results adult education must be integrated into a country's general development plan.
