'This is a valuable guide for policy makers, lobbyists, researchers and students wishing to stay current on the vast array of organisations and individuals involved in the global environmental movement. In this age of increasing globalisation, the ability to network and lobby effectively is greatly facilitated by the existence of such a comprehensive guide. Congratulations on this important and timely work of reference: MAURICE STRONG Chairman, Earth Council Senior Adviser to the President of the World Bank Secretary-General, UNCHE (Stockholm, 1972) and UNCED (Rio, 1992) 'Environment and conservation have become so important today that a guide such as this, edited by someone with the credibility of Nicholas Polunin, will play a very useful role.' Professor JOSE GOLDEMBERG Rector, University of Silo Paulo Former Minister of Education and of Environment, Brazil 'Environmentalists come in all shapes, sizes and disciplines, and this diversity makes them hard to locate in standard works of reference (in which relatively few are represented). This unique volume fills a major gap and will be an invaluable handbook both for people like myself, working in the field, and others who need to find out about various varieties of 'green people'.' Sir MARTIN W HOLDGATE President, Zoological Society of London Former Director-General, IUCN 'This will be a unique and invaluable aid for any person concerned with environmental action in the international arena. The editor has himself exercised a highly productive leadership there over many years: GILBERT F WHITE Gustavson Distinguished Professor of Geography Emeritus, University of Colorado at Boulder.
