Representatives from 14 countries worldwide worked together on improving their monitoring and ultimately their water management to reach the Sustainable Development Goal (SDG) 6 goals by 2030, thereby testing the Information Strategy Model (ISM). This model is developed to support identifying the need for information for water management. In a workshop setting, participants were instructed and subsequently developed the ISM for their own situation. The results show that the ISM fulfils its task of structuring the development and improvement of a monitoring network, but can be enhanced by adding detailed information for specific elements and needs explanation and assistance to be of use.
