Message mapping for abrupt trans-boundary environmental risk communication in river basin

Message mapping is useful for communications which should be easy to understand and reflect the concerns of stakeholders when abrupt trans-boundary environmental pollution occurs in river basin. This paper describes the process undertaken to develop the message maps, and lessons learned thus far. The working group developed a message map for one part of east route of the South-to-North Water Diversion Project(from Yangtze River to Hongze Lake).The message map can help give clear and concise information for stakeholders communication in a crisis where emotions are high, and provides information support for information map visualization in the near future.
