Retired director of medico-social, sociologist and geographer disability practitioner, Serge Alain Bernard, compares the spaces of disability with a dual approach - interdisciplinary and multi-scalar. His work focuses on the status and role of territorial margins and discriminated against in socio-spatial recompositions. The paradigm of spatial justice and injustice largely overlaps with the question of the social-and-spatial margins through which people with disabilities pass. The author shows in what way and how these individuals and these minority groups confronted with social inequalities and spatial injustices, often caught up in processes of marginalization, demonstrate resilience, innovation and creativity which rebound afterwards to the benefit of the whole territory.
