How far apart and away are the education institutions?

IV. Educational objectives and policies
10. At all appropriate stages of their national planning in general, and of their planning for higher education in particular, Member States should take all necessary measures to ensure that:
(a) higher education is directed to human development and to the progress of society;
(b) higher education contributes to the achievement of the goals of lifelong learning and to the development of other forms and levels of education;
(c) where public funds are appropriated for higher education institutions, such funds are treated as a public investment, subject to effective public accountability;
(d) the funding of higher education is treated as a form of public investment the returns on which are, for the most part, necessarily long term, subject to government and public priorities;
(e) the justification for public funding is held constantly before public opinion.11. Higher-education teaching personnel should have access to libraries which have up-to-date collections reflecting diverse sides of an issue, and whose holdings are not subject to censorship or other forms of intellectual interference. They should also have access, without censorship, to international computer systems, satellite programmes and databases required for their teaching, scholarship or research.

15. Member States and higher education institutions should, nevertheless, be conscious of the exodus of higher-education teaching personnel from the developing countries and, in particular, the least developed ones. They should, therefore, encourage aid programmes to the developing countries to help sustain an academic environment which offers satisfactory conditions of work for higher-education teaching personnel in those countries, so that this exodus may be contained and ultimately reversed.
