We fully agree that there is not a single path or model for building public governance that favors sustainability. In this regard, we have stressed, on several occasions, that social contract formation takes place in polycentric ways at different levels (always context-specific and path-dependent). Challenges related to sustainability, social inequalities, or public governance, regardless of whether it takes place in the North or South, call for transformation-oriented forms of governance which are capable of dealing with complexity, ambiguity, and uncertainty.
The line-up moves from high abstraction level (figure 2), towards a tool for identifying options for co-evolutionary steering (figure 3), to an example of leverage points for a specific transition path (figure 4).
