Over the next years we are likely to experience global changes at a rate and scale that is unprecedented in human history. Many people are concerned about the future – and frustrated because there is currently so little evidence of actions at the scale and magnitude considered to be necessary to meet complex challenges like climate change. We often hear talk about leverage points for large-scale systems changes, or about the role of “trim tabs,” whose small moves can make a powerful difference. But how do we actually make change happen? Do we ourselves need to change? To more effectively contribute to collective change, we need to have more hands on knowledge about change mechanisms and how to get around the blind spots – and experience it first-hand so that we can work better with others.
