The history of the European Grassland Federation (EGF) from its founding in 1963 to 2003 is described. The origins and constitution are described together with its membership. How the structure and functions of the EGF have changed in 40 years are outlined and the management and financial arrangements of the EGF explained. The background to Grass and Forage Science becoming the official journal of the EGF in 1996 is described. The developments that have take place in the content and size of the General Meetings and Symposia, and in their publication as Proceedings, are highlighted. The links to other organizations in grassland research and the future direction of the EGF are explored. 相似文献

For many centuries, human activities have become progressively more significant forces in the biogeochemical circulation of matter in the earth. In recent decades, the phenomena and effects of acidification have played a central role in scientific and social learning about both human impacts on ecosystems and the importance of regional, international, and global strategies in environmental protection.The history of acidification research and policy analysis in Europe and North America is reviewed in an attempt to discover lessons that can be learned from past successes and shortcomings in environmental research and policy. 相似文献
