So, what is the theme for the Jam?
Of course, the overarching theme of the Jam is Sustainability - but there will be a special Secret Theme for the weekend too. This Secret Theme will carefully chosen by representatives of the worldwide organising team, and kept Top Secret until it is announced on the Friday evening (local time) in each location.
We expect the Theme will be quite abstract, to allow a wide range of practical applications, depending on the participants' interests.
Here's an example from the Global Service Jam - a sister event to the Global Sustainability Jam, but one which creates only services. Last year, it had the theme: "(Super)HEROES". The participants interpreted it in many different ways, producing many different types of services based on sharing, helping, empowerment, or even super-powers.
The Global Sustainability Jam is more about tools, methods, people, ideas and exchange than any particular field of application.
