The Italian National Group for the Prevention of Hydrogeological Disasters has been created under both multidisciplinary and interdisciplinary frameworks, necessary for advancing research activities in the sphere of hydrogeological hazards. The Group collaborates with relevant institutions abroad not only in its research activities but also in organizing seminars and summer schools. In this paper, the activities of the Group carried out in preparation towards the United Nations declaration of the IDNDR and subsequent ones under the Decade are presented. The paper concludes with proposals for integrated data collection activities on hydrogeological hazards and a drought monitoring observatory within the context of an impending climate change.
