Mark Swilling

synchronicity, synergy & energy

Mark’s research over the past three decades has addressed many issues, but the core focus has been transition. During the 1980s and early 1990s, his focus was on the transitions to democracy that swept across Latin America, Southern Europe, Eastern Europe and then Africa in the 1990s (including SA in 1994). During the 1990s his focus was urban transition, with special reference to the building of the Lynedoch EcoVillage from the late 1990s. From the early 2000s, his focus has been on sustainability transitions culminating in various publications including his co-authored book Just Transitions in an Unfair World (2012). Drawing on many different intellectual influences (Dutch transition theory, African philosophy, Roberto Unger’s theory of change, long-wave thinking, state theory (especially Jessop) and anticipatory thinking, Mark’s latest book (The Age of Sustainability) provides the basis for his work at GEJP. He intends to focus on energy transition and the collibratory governance of non-equilibrium economic dynamics.
