Special Section of Leonardo Transactions Water Is in the Air Annick Bureaud and Roger F. Malina, Guest Editors We are pleased to present a selection of papers presented at the Water Is in the Air workshop, held 25–26 June 2012 in Marseille, France. Recognizing that water is at the core of many eco- nomic, social and political issues as well as cultural and symbolic ones, the workshop presented and discussed trans-disciplinary topics, using artistic and scientific projects about water as case studies. The workshop was organized by Annick Bureaud, Roger F. Malina and Pascale Hurtado under the auspices of the European StudioLab consortium led by the Science Gallery in Dublin, and was hosted by IMéRA, the Institut Méditerranéen de Recherches Avancées at the Aix Marseille University. Video documentation of all the talks is available online at <www.olats.org/studiolab/eau.php?in=acte>. ————————————————————— Transactions publishes short refereed papers, providing a fast track to publishing key new results, ideas and developments in practice.
