KNOW4DRR explores how knowledge on mitigation and adaptation is produced, shared, maintained, and used (or not used ) by a variety of stakeholders. It aims at identifying barriers to knowledge use and sharing as well as potential bridges among experts and professionals with different disciplinary backgrounds and different roles. The creation of tools to enhance societal capacity to learn from past successes and mistakes and update its knowledge on natural extremes and climate change potential consequences is part of the project’s effort through workshops, seminars, and living labs.
