This study presents the first assessment of how an approach based on meeting fundamental human needs can assist regional planning. It uses the Human-scale Development methodology, based on fundamental human needs as a theoretical and methodological framework for scenario building. It offers a structured approach on how non-monetary values and practices (i.e. satisfiers or ways to satisfy needs) can help to open up the planning process, highlighting a regional conflict. The study presents three dimensions of needs to address planning challenges. (...) The data is taken from a case study of a deliberative process for regional planning in Western Europe. The relevance lies in the ways we can learn from individual values and practices, that when shared with others, (1) help to diagnose behaviours and trends toward environmentalism; (2) foster listening and understanding of people's sameness and differences that reduce conflict; and (3) provide a structured tool which predicts society dynamics and develops integrated solutions that facilitate sustainable regional development.
