This is the 2nd Call for applications for Short-Term Scientific Missions (STSMs) funded by the COST Action CA20138 “Network on water-energy-food nexus for a low-carbon economy in Europe and beyond-NEXUSNET”. STSMs allow scientists to conduct short research and study visits to a research institution or laboratory in another COST Country to strengthen the existing networks and foster collaboration, learn a new technique, or use equipment, data, and/or methods not available in their own institution and contribute to the scientific objectives of the Action.
