2.3 Why we value play

Play is notoriously difficult to define, but this in itself is not problematic. What is important is that practitioners, parents and children within a setting share their ideas about what constitutes play and that we, as adults, are clear about why we value play. In order to do this, you need to take a step back and think about what you think play does and, from there, consider why it is valuable.

Uncertainty, Lags and Nonlinearity: Challenges to Governance in a Turbulent World
Prof. Homer-Dixon looks at systems displaying high levels of uncertainty. Using the example of climate change, he asks whether standard "management" approaches used by policymakers are enough or if we must find new approaches in times of uncertainty. Global financial, climate, energy, and food challenges exhibit similar characteristics - all emerge from systems exhibiting high levels of uncertainty, countless unknown unknowns, time lags, threshold effects, occasional chaotic behavior, and someti
