Frontiers in Sustainability (FinS) is an edited book series by MDPI. It serves as a transdisciplinary and multistakeholder platform for regional and global sustainability issues. Here, we understand transdisciplinarity as a collaboration between researchers from different disciplines to conceptualize, study, and derive solutions to sustainability-relevant problems that may be relevant to stakeholder practices and outcomes beyond academia. FinS promotes debates within and between academic disciplines, especially the natural sciences, engineering and technology, and the social sciences, and it seeks to publish academically relevant exchanges between academia, intergovernmental and non-governmental organizations, politics, and business.
