The author discusses how institutions adapt to changing social and environmental conditions. Based on case study evidence, I argue that community-based natural resource management works best in a context of institutional collaboration and shared learning. The author identifies three requirements for collaboration: the need for effective facilitation of experimental learning, equal power in learning process and the willingness to engage in multi-stage process that can be costly.
