Successful Implementation of Environmental Policy and Governance: Understanding and Modeling Micro Governance

Environmental Policy and Governance, EarlyView.
ABSTRACT Successful implementation of environmental policy and governance highly depends on the capacity to know about, build new and utilize existing governance structures. However, the theoretical tools and available methods to assess the complexity of emerging or existing structures are rather limited.
