This practical guide provides a step-by-step approach to implementing the Climagine methodology for Integrated Coastal Zone Management (ICZM) practitioners. Co-developed by Plan Bleu, Climagine is a systemic and participatory foresight methodology that brings together stakeholders to explore sustainable futures, identify key sustainability challenges and indicators, develop alternative scenarios, and translate shared visions into actionable coastal management and climate adaptation strategies. Drawing on more than a decade of field experience across Mediterranean coastal areas, the guide offers practical tools, templates and lessons learned to help practitioners adapt and implement the methodology in different territorial, governance and data contexts.
