The document discusses the development of an M&E (monitoring and evaluation) framework for evaluating transboundary collaboration in marine spatial planning. It provides an overview of the framework, which is based on a literature review and project interviews/observations. The framework focuses on cross-border MSP collaboration and provides guidance on evaluating such processes. It introduces a theory-based evaluation approach using a logic model to understand how MSP plans and policies produce change through activities, actions, outputs and outcomes. The document is being updated based on additional analysis and comments are requested by the end of August to further improve the framework.
