Hosting mega-events can not only catalyse urban development, but also lead to an improvement of local planning systems and building planning capacity. Events can create knowledge transfer from one city to another, and be used as tools for experimenting new prototypes and urban templates but on a smaller scale. Within this context, this research aims at identifying strategies for leveraging mega-events to improve local planning capacity. Relevant best practices in the use of events as planning enhancers are derived from the literature, and then applied to a case study, the city of Doha. In fact, the capital of Qatar has all the characteristics for benefiting from events. Firstly, it is a city that has already and will host in the imminent future many international events. Secondly, Doha is managing with difficulties its rapid urban development, and needs to improve its planning system. Results show there is a potential for benefiting from events in two ways: they can assist knowledge transfer from international consultancy to local agencies, and vice versa. In addition, events can act as the glue for overcoming the fragmentation of Doha’s planning system, by facilitating the implementation of 2030 Qatar National Vision, the country’s comprehensive blueprint.
