The edge is the meeting point between the known and the unknown, between something being too well known, which makes it boring to us, and too unknown, which makes it confusing. The edge is a zone of high intensity, instability, creativity and innovation. Just as it is possible, through the design of ecologically sustainable systems, to increase diversity and life by maximising the edges between neighboring biological communities, so it is possible to create a larger edge effect in community development, thereby maximising its benefit to the society as a whole. This module will position Gaia Trainers as maximisers of edges between different communities with differing modes of operation, power structures, cultures, physical environments and worldviews. It will equip trainers with the skilful means to adapt to multiple scenarios and situations and ultimately thrive and help others thrive through creativity and playing for collaborative advantage.
