This book on international harmonisation and equivalence in organic agriculture, is but one of the many outcomes from The Conference on International Harmonisation and Equivalence in Organic Agriculture organised in February 2002 by the International Federation of Organic Agriculture Movements (IFOAM), in cooperation with the Food and Agriculture Organization of the United Nations (FAO) and the United Nations Conference on Trade and Development (UNCTAD). This publication includes many contributions from the original Conference Reader (edited by Willie Lockeretz and Gunnar Rundgren) as well as a considerable amount of new material from presentations made at the conference. It shows the wide spectrum of topics involved in the process of harmonising organic guarantee systems as well as different approaches to the subject. The result is a comprehensive publication for all stakeholders in the various fields connected with organic guarantee systems. As most articles are based on the Conference respectively the Conference Reader, it is important to note that they are updated as of February 2002
