From 23^rd April to 28^th April, Prof. Kaiheng Hu from the Institute of Mountain Hazard and Environment led the delegation to participate in the  General Assembly 2017 of the European Geosciences Union. This conference has covered several disciplines and fields, including natural hazard, climatology, pedology, marine sciences, geochemistry, geophysics, hydrology sciences, energy resources with environment and space sciences, which attracted about 14000 experts and researchers from 107 countries all over the world. The participatingdelegationof IMHE was composed of scientific researchers from several departments and disciplines, including Key Laboratory of Mountain Hazards and Earth Surface Process, Key Laboratory of Mountain Surface Process and Ecological Regulation, Mountain Development Research CenterDigital Mountain and Remote Sensing Applications Center, and Editorial Office of Journal of Mountain Science. 

During the period of conference, researchers like Prof. Kaiheng Hu, Prof. Hong Xie, Prof. Jianrong Fan and ect. introduced  the prevention and treatment of mountainous torrents and debris flows, remote sensing in disasters, prediction of rainfall-induced landslide, soil physical features, natural disaster with mountainous area development and the research achievements about disaster prevention and treatment along the Belt and the Road in the form of parallel session report, oral presentation and poster ect. Also, they conducted extensive academic communication and interaction with international scientists from all over the world. The representative from editorial office of Journal of Mountain Sciences (English Edition) made some propaganda in the Springer Exhibition Area and had some interactions with editorial board members, authors and reader in the worldwide. The academic lecture and theme activities delivered and conducted by the delegation had a great effect and attracted much attention of the experts in relative discipline. 

On the sidelines of the conference, Prof. Hu visited the cooperation organization of the IMHE, the Institute of Risk Engineering in Mountainous Area in University of Natural Resources and Life Sciences, Vienna, by leading the members of delegation. Prof. Hu introduced the recent works of IMHE in monitoring and early warning of mountain hazards, prevention and treatment in engineering cases, international disaster and risk reduction about the Belt and the Road, to the general director of the institute, Prof. Hübl. Prof. Hübl thought highly of the recent research works of the IMHE and hoped that the cooperation between both sides could be strengthened in the aspects of applying for international cooperation projects, reducingdisastersin the Belt and the Road and academic exchanges. 

This visit and communication has promoted the international influences of the IMHE, and would help to establish a solid foundation for the deepening the cooperation  academic exchanges with the American and European developing countries in mountain hazard, mountain environment and mountainous area development.
