This collection of papers addresses the issues surrounding communication of environmental geoscience. Geologists whose research deals with environmental problems such as landslides, floods, earthquakes and other natural hazards that affect people's health and safety, must communicate their results effectively to the public, policy makers and politicians. There are many examples of geological studies being ignored in policy and public action; this is in due in part to geoscientists being poor communicators. These papers document issues in communicating environmental geoscience, outline successes and failures through case studies, describes ways in which geoscientists can improve communication skills and show how new methods can make communication more effective.
