First published in 1991. The European Association of Development Research and Training Institutes (EADI) organised its 6th General Conference in Oslo, 27-30 June 1990. The general theme was 'New Challenges for European Development Research', with particular reference to the changes taking place in Europe, East and West, and to sustainable development. More than 200 papers were presented - in the plenary sessions, in two parallel, special sessions on the two main themes, and in the sessions of 23 working groups and five ad hoc panels. It is from this harvest that the editors of the previous and the present issues of the EJDR have selected contributions. No.2 (1990) focused on the changes in Europe and their effects. The present issue focuses on the other main theme of the conference, sustainable development.
