Water, energy and food are closely connected sectors which interact in a complex manner. Complex problems which need to be addressed in these sectors require informed decisions. The key to this information are data which need to be easily available to the decision maker. In the context of the Sustainability in the W-E-F Nexus conference May 19-20, 2014, the session on ‘Earth Observations, Monitoring and Modelling for the Sustainable Implementation of the Nexus Approach’ revealed institutional shortcomings and general problems in data provisioning for the water-energy- food (WEF) nexus. Key Findings of the session were that (1) integrative thinking of collaborating institutions is required to address problems in the water-energy-food nexus, (2) comprehensive and coherent data need to be made readily available, potentially through the Global Earth Observation System of Systems (GEOSS) and (3) that nexus education needs to be promoted in basic and higher education in order to ensure efficient use of coherent and comprehensive datasets.
