World Water Week is hosted and organised by the Stockholm International Water Institute (SIWI) and takes place each year in Stockholm. The World Water Week has been the annual focal point for the globe's water issues since 1991. Every year, over 200 collaborating organisations convene events at the World Water Week. In addition, individuals from around the globe present their findings at the scientific workshops.
Each year the World Water Week addresses a particular theme to enable a deeper examination of a specific water-related topic. While not all events during the week relate to the overall theme, the workshops driven by the Scientific Programme Committee and many seminars and side events do focus on various aspects of the theme. 2013 theme is Water Cooperation - Building Partnerships.
