At work, I have been part of a team working on a project aiming to support second year university students enhance their interdisciplinary learning, thinking and working skills.  We have designed this process to enable students to do this through a central theme:  Living in a world of 10bn.  In addition to online and off line learning, one of the elements of the learning journey involves their participation in what we are calling the Festival of 10bn.  Toward that end, I contributed by hosting, in collaboration with three organisations, a meal derived out of food that is
surplus.  Here is the storify of that event.
