The Andes mountain range extends through seven countries in South America. The cultural, political and economic aspects vary widely, and so do the impacts and responses to hydroclimatic events. Against this background, the Bern University of Applied Sciences, through the projects ENANDES “Enhancing Adaptive Capacity of Andean Communities through Climate Services” and ENANDES+ “Building Regional Adaptive Capacity and Resilience to Climate Variability and Change in Vulnerable Sectors in the Andes”, examines the flow of climate information in different contexts the countries and assesses how socio-political-economic aspects might lead to different cooperation possibilities and user responses. One of the biggest challenges is to get the information to the users in such a way that they can use it effectively Some National Meteorological and Hydrological Services (NMHS) deliver information directly to the users other NMHS rely on a complex network of institutions that evaluate and modify the CS before it gets to the users. This results in a final product that differs in content, frequency, and channel from the NMHS These different approaches make it necessary to analyze the structures of the information flows in addition to the production of the service and the co-production spaces between CS and end users. Knowing the potentials and limitations of the flow could allow can contribute to the adaptation of the service and the configuration of the User Interface Platform (UIP) to the local conditions. It gives insights on how to accelerate institutional linkages and changes in the CS, which is crucial particularly considering EWS.
