The multi-level governance imperative.

Governments are facing increasingly complex policy challenges, ranging from climate change, demographic pressures, rising inequalities and discontent, to the global health crisis that countries are presently confronting. Successful responses require more integrated approaches to policy making at all levels of government, so that economic, social and environmental actions reinforce each other rather than compete. They also require effective coordination across levels of government to manage shared responsibilities, mutual dependence and common challenges. This commentary highlights the progress in the multi-level governance concept since its first use, and focuses on some current dynamics driving multi-level governance, in particular the trend towards differentiated subnational governance. It then highlights that the way multi-level governance systems are designed has a direct impact on policy outcomes, hence the imperative to strengthen multi-level governance systems. The commentary offers insight into how the Organisation for Economic Co-operation and Development is tacking this imperative to best support countries in their development processes.
