THE International Council on Social Welfare (ICSW) has prepared this Summary of Principal Commitments as part of our extensive efforts to promote implementation of the agreements made at the World Summit for Social Development.    ICSW is a global non-governmental organisation which represents organisations in more than 70 countries that are especially concerned with improving social development, social welfare and social justice. Most of our members are from developing countries, where rapid progress in these areas is especially crucial.        ICSW gave a very high priority to preparation for the Summit and, amongst other activities, was closely involved in drafting extensive passages of the documents which were agreed in Copenhagen. We were always aware, however, that the length and diversity of the agreements could be a deterrent to people who were not familiar with them.        We hope that this brief Summary will be a useful introduction to the structure and scope of the Copenhagen agreements, and an overview of the key priorities and actions to which the world leaders committed themselves and their countries.         Since the Summit in 1995, ICSW has commenced publication of a quarterly  magazine, Social Development Review, which disseminates information, analysis and ideas about issues relating to implementation of the Copenhagen agreements. We have also organized global, regional and national forums of non-governmental organisations to assess and promote Summit implementation. A further extensive series of forums is being conducted in preparation for the UN’s Special Session on the review of the Summit in the year 2000.        We wish to acknowledge the invaluable financial support provided for these activities by a number of principal donors including the governments of Canada, Denmark and the United Kingdom, as well as the United Nations Development Programme and the Friedrich Ebert Stiftung.         ICSW firmly believes that the World Summit for Social Development is of great global significance. We invite others to join in the struggle to achieve its implementation. We would especially welcome participation in our series of forums, and information or suggestions about other action to promote implementation of the Copenhagen commitments.   Julian Disney President International Council on Social Welfare
