Mike Osborne and Kasia Borokowska were very pleased to be able to represent the SUEUAA project at the second meeting in London on 19 June of projects funded with the British Academy's Cities and Infrastructure Programme with the Global Challenges Research Programme. We were joined by representatives of other projects, each reporting on their progress. It became very evident that much synergy exists within the programme, and we were very pleased to be approached by colleagues from Mexico interested in joining our project.
