Learning from Other Places and Their Plans: Comparative Learning in and for Planning Systems

In this thematic issue we pursue the idea that comparative studies of planning systems are utterly useful for gaining a deeper understanding of learning processes and learning capacity in spatial planning systems. In contemporary planning systems the pressures towards learning and continuous self-transformation are high. On the one hand more and more planning is needed in terms of integration of expertise, policy, local knowledge, and response to long term environmental challenges, while on the other hand the value of planning systems is increasingly questioned and many places witness an erosion of planning institutions. The issue brings together a diversity of contributions that explore different forms of comparative learning and their value for any attempt at reorganization, adaptation and improvement of planning systems
