Organized by Institute of Tibetan Plateau Research, Chinese Academy of Sciences, Research Center of Water and Soil Conservation and Ecological Environment, CAS &Ministry of Education, Institute of Soil and Water Conservation, Northwest A&F University, International Research and Training Center on Erosion and Sedimentation, State Key Laboratory of Tibetan Plateau Earth System, Environment and Resources, State Key Laboratory of Soil Erosion and Dryland Farming on the Loess Plateau, and the World Association of Soil and Water Conservation, the International Workshop on Soil Erosion and Riverine Sediment in Mountainous Regions was held successfully on line during November 17-18th, 2022.

The goal of this workshop is to invite well-known experts in related fields to exchange the latest research results, identify the current opportunities and challenges, and discuss the strategies to deal with climate change through online and offline means.

In the opening ceremony, Prof. Fahu Chen, from Institute of Tibetan Plateau Research, CAS, Prof. Hao Feng, from Research Center of Water and Soil Conservation and Ecological Environment, CAS & MOE, and Prof. Qingbin Pan, from the International Research and Training Center on Erosion and Sedimentation were invited to give opening speech.

Totally 24 experts from Italy, Germany, Singapore, USA, Canada, China provide wonderful academic presentations, attracting about 200 researchers to participate online. Finally, Prof. Fan Zhang from Institute of Tibetan Plateau Research, Chinese Academy of Sciences and Prof. Shaoshan An from CAS &Ministry of Education, Institute of Soil and Water Conservation co-chaired the discussion session of the conference, in which they drafted the " Declaration of opportunities and challenges for the study of soil erosion and river sediment in mountainous regions around the world" and discussed new research directions and goals for the future, expecting to make more contributions to basic science research and provide more opportunities for sustainable. We expect to make more contributions to basic scientific research and provide more scientific wisdom to improve the ecological environment and enhance human welfare.
