EXIT aims at providing an in-depth analysis of ‘left-behindness’ as a concept used for characterising territorial inequalities faced by certain areas and, grounded on this, identify strategies to address it. This means not only building knowledge on drivers of inequalities in areas that are characterised as ‘left-behind’, but also on what drives perceptions of these areas as ‘left-behind’. To do so, EXIT proposes bottom-up, interdisciplinary and mixed-methods research with a community-based and intersectional approach from the analysis to the transferability of practices.
